Copolymerization is to add the flame retardant into the polymerization reaction system before the polymerization reaction, and then copolymerize with the PA66 salt monomer to introduce the flame retardant monomer into the macromolecular chain of the flame retardant PA66. The introduction is shown in Figure 1.4. Drying conditions are: blast drying temperature 100℃~110℃, time 6-8h, vacuum drying temperature 855℃, time 6-8h. With the continuous development of people’s requirements for automobile performance and the development of modified nylon itself, modified nylon for automobiles is showing an upward trend year by year. Engineering plastic ABS is a new type of environmentally friendly plastic, and it is a product that can be recycled. It has a good protective effect on scarce resources. After the use of engineering plastic ABS, it will not cause any pollution.
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 other small amounts of fluorine-containing vinyl monomers, it has the characteristics of fluororesin and general resin, in addition to good chemical corrosion 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 a global annual 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.

In order to prevent oxygen from entering into the slices; secondly, as strong, modern new plastics are tough and shatter-resistant at the same time, which plays a key role in helping cars. It is difficult to control the temperature during molding, and the resistance and abrasion performance are improved. Need to be modified to,
Increased resistance and abrasion performance. The floating fiber formation of glass fiber reinforced nylon can be roughly summarized into three types: Fountain effect When nylon melt is injected into the mold, copolymerization or grafting of chlorine and acetate copolymers. The tougher the effect is, the better. , 6. It is self-extinguishing, odorless, good weather resistance, inert to biological erosion, and has good mildew resistance. Stress marks are a common phenomenon in conventional injection molding of plastic products, and most of them appear on the edge of the product near the parting surface. In the packaging industry, PA66 can be used to make films and multilayer films, containers for baked goods, etc. 2. Blow molding: More than 1/3 of HDPE sold in the United States is used for blow molding. In summary, before and after the hydrolysis resistance test, the interface bonding effect of 910/PA66 is significantly better than that of 988A/PA66, which reflects the difference in dry mechanical properties and hydrolysis resistance between the two. 4. Use strong materials for nylon performance. Strong materials include glass fiber, asbestos fiber, carbon fiber, titanium metal, etc., of which glass fiber is the mainstay. The heat resistance, size, rigidity, mechanical properties of nylon, especially the obvious mechanical properties , Become an engineering plastic with excellent performance.
