(Summary description)Characteristics

Ortho-phenylphenol, a white flake crystal, is an important new fine chemical product and organic intermediate. It is widely used in sterilization, anti-corrosion, printing and dyeing auxiliaries and surfactants, as well as stabilizers for the synthesis of new plastics, resins and polymer materials. Its specific uses are as follows:

Antiseptic and antiseptic
Because o-phenylphenol and its sodium salt have high herbicidal activity, broad-spectrum bactericidal and mildew-removing capabilities, and are non-toxic and tasteless, they are good preservatives and can be used for anti-mildew and fresh-keeping of fruits and vegetables, especially for Anti-mold citrus, can also be used to treat lemons, pineapples, melons, fruits, pears, peaches, tomatoes and cucumbers, etc., to minimize decay.

Dyeing vector
Ortho-phenylphenol and its water-soluble sodium salt can be used as a dye carrier for polyester fibers, and can also be used as a carrier when dyeing hydrophobic synthetic fibers such as chlorinated fiber and polyester.

Flame retardant material
When the polymer material containing organic phosphorus compounds is burned, a graphite-like carbonized film will be formed on the surface of the material to isolate the polymer from the air. It has good flame-retardant properties, high flame-retardant efficiency, low volatility, oil and hydrolysis resistance It has good performance and is more and more widely used, and will gradually replace the inorganic and halogen-containing flame-retardant materials used today. Using o-phenylphenol as a raw material, a new type of phosphorus-containing flame-retardant intermediate DOPO can be synthesized, mainly for the following applications:

(1) Flame retardant polyester
DOP0 is a raw material that reacts with itaconic acid to produce intermediate ODOP-BDA, which can partially replace ethylene glycol to obtain a new type of phosphorus-containing flame-retardant polyester. Studies have shown that when the phosphorus content in PET and PEN reaches 0.75% and 0.5%, respectively, polyester exhibits a good flame-retardant effect. The world's annual production of polyester has reached more than 30 million tons. If 5% of it is phosphorus-containing flame-retardant polyester, more than 50,000 t/a of o-phenylphenol is required.

(2) Epoxy resin
Epoxy resin has excellent bonding properties, electrical insulation properties and other advantages. It is widely used in adhesives, electronic instruments, aerospace, coatings and advanced composite materials. In 2004, the consumption of epoxy resin in the world reached more than 200,000 tons. /year. DOPO reacts with benzoquinone to form ODOPB, which partially replaces bisphenol A and forms a new flame-retardant epoxy resin. Studies have shown that the newly synthesized phosphorus-containing flame-retardant epoxy resin has a better flame-retardant effect than the Br flame-retardant epoxy resin containing 17.26% when the P content is 2.1%, and does not produce smoke, and has excellent thermal stability. For epoxy resin without added flame retardant.

(3) Organic dissolution
Using DOPO as raw material, the synthesis of 2DOPO-A partially replaces the synthetic polyamide monomer DABP. The resulting new polyamide is soluble in solvents such as NMP, DMAc, DMF and DMSO. At the same time, it has thermal stability and flame retardancy at high temperatures. Sex has also improved significantly.

(4) Antioxidant
The Taiwan patent reported the use of DOPO to synthesize phosphorus-containing antioxidants, antioxidants for unsaturated polyesters, phenols and greases, and Formosa Plastics Group for copper-based sheets for computers, and it has good thermal stability.

(5) Stabilizer
The Japanese patent reported the stabilizer of polymer materials synthesized by DOPO. Adding this compound during the processing of polyethylene, polypropylene, and polyvinyl chloride can improve the stability of polymer compounds during thermal processing.

(6) Luminous matrix
Organic light-emitting diodes are important optoelectronic materials. Sun et al. used DOPO derivatives as monomers to synthesize polymers with light-emitting properties. DOPO derivatives act as emission groups and can emit blue light with a wavelength of 325-350nm, which can be applied to Organic light-emitting diodes.

Agglomerate
Phenolic resin has the advantages of high mechanical strength, good electrical insulation performance, excellent heat resistance, and flame retardancy. It is widely used in the preparation of glass fiber reinforced plastics, molding compounds, coatings, adhesives, etc. However, phenolic resins also have disadvantages, such as heat resistance. Poor performance, etc. Replace phenol with o-phenylphenol to synthesize a new phenolic resin, which has high thermal stability and low water absorption.

New drugs
According to related reports, o-phenylphenol is used to synthesize cholesteryl ester hydrolysis inhibitors, antispasmodic drugs, anti-inflammatory drugs and analgesics,

The envelope bag has a tongue like an envelope. A strip of glue is attached to the tongue, which can be folded to seal the bag. General clothing is used more. There is also a courier bag which is actually a kind of envelope bag. 　　5. The punching tote bag is to punch a hole at the top of the flat pocket to facilitate the lifting of the bag. 　　6. ​​The handle bag is to add a plastic film strip on the top of the bag to facilitate the lifting of the bag. This process consumes labor and is relatively expensive. 　　7. The zipper bag is to install a zipper strip and a zipper cap on the sealing part of the bag. 　　 8. PE film is the film that is not made into a bag after being blown out by the machine. It is also divided into stretch film and shrink film. Commonly used in the market are counted by one and counted by length (roll). (A) The small bag is mainly used for the packaging of small accessories, electronic products Most of the accessory bags of the products have anti-static effect, and the mouth of the bag is divided into flat mouth and self-sealing structure. The latter is also called bone bag (PE bone bag) or compact bag; (Roll) bags need to be cut by themselves (for material packaging) and printed cuts (for supermarkets). In addition, the cling film made of PE material can also be called a PE bag. Note that the cling film directly in contact with food must be made of PE material (the other is generally PVC), which is safer for the human body. Resolution method: The transparency, stretchability and viscosity of PVC cling film are stronger than PE cling film. When the PVC cling film is burned with fire, the flame will turn black, emit black smoke, have a pungent smell, will not drip oil, and will automatically go out after leaving the fire source. When the PE cling film burns, the flame is yellow, odorless, dripping oil, and can continue to burn after leaving the fire source.

Heat shrinkable film is mainly used for labels, heat shrinkable packaging or stretch film. The polymer resins suitable for preparing heat shrinkable film mainly include PVC, PE, PS, PET, etc. After the film is preheated, it is stretched, cooled and shaped (as long as it is not subjected to heat-setting treatment) to obtain a heat shrinkable film. Under the Tf close to the resin, the resin cast sheet is stretched in the transverse and longitudinal directions, and then quenched, so that the resin molecular chains are frozen in an oriented state, forming a heat shrinkable film. It is a process of entropy reduction from the raw material to the production of heat shrinkable film. The thermodynamic state of heat shrinkable film is unstable. When the shrinkable film is heat-treated, the oriented molecular chains will quickly return to random coils (curved state). , The film shrinks. This feature of the heat shrinkable film can be used to prepare labels for special-shaped bottles. From the perspective of functional requirements, heat-shrinkable sleeve labels have the characteristics of moisture-proof, anti-corrosion, impact-resistant, tear-resistant, odorless and non-toxic; they can play a role in anti-counterfeiting; protect consumers from damage or rupture of the container. accidental damage. The most important thing is that this label can be recycled, which has significant advantages in saving costs and protecting the environment. However, there are also many difficulties in the design process of heat shrinkable sleeve labels. When producing heat-shrinkable sleeve labels, the most widely used film material in the market is PVC heat-shrinkable film. This kind of film has many advantages such as waterproof, fire resistance, high transparency, high gloss, high shrinkage rate, etc., but the material is prone to produce toxic gas when burned, which is not conducive to environmental protection. As a new material, OPS heat shrinkable film is a kind of skin packaging material that meets environmental protection requirements. It has many advantages such as high strength, high rigidity, good gloss, high shrinkage, and compliance with food hygiene standards. However, due to the current market There are not many companies that produce this film in Shanghai, and they cannot fully meet the market demand for this film. For the ink, the quality of the ink directly affects the printing effect of the heat shrinkable sleeve label. Practice has proved that UV flexo printing ink is a very good choice, and its biggest advantage is that it can achieve higher color strength through curing and drying, which also brings great challenges to traditional gravure inks.
