Nowadays, automotive, home furnishing, electronics and other industries are more and more widely used. Jawed uses phosphorus-containing carboxylic acid and hexamethylene diamine to synthesize a salt, and then uses adipic acid and hexamethylene diamine to synthesize a PA66 salt. The two salts are co-condensed according to a certain ratio to prepare phosphorus-containing flame-retardant copolymer PA66. Because the benzene segment in SMA has good compatibility with ABS, the compatibility of PC/ABS is improved. Although the effect of inorganic materials on nylon toughness may not be as good as the effect of elastomers, it can also achieve the tensile strength of nylon when it is resistant to the edge of Niutto. It is more reasonable to choose polyolefin for toughness,
Polyvinylidene fluoride
Poly (vinylidene fluoride), the English abbreviation PVDF, mainly refers to vinylidene fluoride
Pvdf molecular formula ethylene homopolymer or copolymer of vinylidene fluoride and a small amount of fluorine-containing vinyl monomers, it has the characteristics of fluororesin and general resin, in addition to good chemical resistance, high temperature resistance, and oxidation resistance In addition to weather resistance and radiation resistance, it also has special properties such as piezoelectricity, dielectric properties, and thermoelectric properties. It is the second largest product among fluorine-containing plastics, with an annual global production capacity of more than 53,000 tons.
In the chemical structure, a fluorine-carbon bond is used. This structure with short bond properties forms the most stable and strongest bond with hydrogen ions. Therefore, fluorocarbon coatings have specific physical and chemical properties, not only have strong wear resistance and impact resistance, but also have high fading resistance and UV resistance in extremely harsh and harsh environments.

The main types of modified plastic products include flame-retardant resins, tough resins, plastic alloys, and functional masterbatches. The selection of electrical equipment materials is very important. When the same product is used differently, the materials should also be selected according to specific requirements. The smoke, toxic, and corrosive gases produced at times are harmful. The main component is that, in response to this problem, halogen-containing flame-retardant nylon will gradually be eliminated. Cao Minqian et al. adjusted the blending ratio of PC and ABS resins to produce various PC/ABS alloys with different characteristics. 1. PC/ABS alloy ABS plastic currently on the market has good surface hardness and gloss, but it is used in LED TV frames, digital product housings, etc., in terms of gloss, brightness, surface hardness, scratch resistance and abrasion resistance. Sex and other aspects are slightly insufficient.
Third, the content of strong nylon glass fiber is still a choice. With the rapid economic development and rapid living standards, the domestic market for home appliances is expanding rapidly. We have done two kinds of toughener grafting EPDM and grafting POE. From the perspective of subdivided species, good injection molding performance and appearance. If antioxidant 1098 and imide antioxidant 626 are used in combination, they will have a synergistic effect in the PA6 system. ④ Process control. For example, plastic nets used in marine aquaculture, later, plastic recycling and recycling provide opportunities for circular economy, and conform to the ever-growing market development agenda.
