Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a special super-tough nylon for blow molding. Background technique [0002] Nylon (PA), the scientific name is polyamide, has many types, such as PA6, PA66, PA9, PA1010 and so on. Nylon has become the most widely used type of engineering plastics due to its high strength, good wear resistance, and good processing fluidity. Among them, nylon 6 is a common engineering plastic with good performance and can be widely used in the fields of automobiles, machinery, construction, electronic appliances and weapons and equipment. Nylon materials have a series of advantages such as high strength, good wear resistance, and good impact performance, but nylon materials have shortcomings such as poor low temperature toughness, poor acid and alkali corrosion resistance, high water absorption, and poor oxidation resistance. These shortcomings are serious. Limits the use of...

Problems solved by technology

Nylon material has a series of advantages such as high strength, good wear resistance, and good impact performance, but nylon material has shortcomings such as poor low-temperature toughness, acid and alkali corrosion resistance, high water absorption rate, and poor oxidation resistance. These shortcomings are serious. Limits the use of nylon materials

[0003] In the prior art, there are many methods for modifying nylon to improve its performance. CN108329686A discloses a preparation method of a high-performance nylon nanocomposite material, which uses polyamino acid modified nanoparticles to modify nylon to improve the mechanical properties of nylon. performance, dimensional stability, but its modification process is complicated, and it is difficult to carry out large-scale production; CN102382452A discloses a preparation method of nano-modified nylon composite material, and the nano-modifier described in it is polyhedral oligomeric siloxane (POSS), its made nano material has higher toughness and strength; CN109836813B discloses nylon 6 composite material and preparation method thereof, and it passes through the nano SiO of adipic acid graft modification 2 As one of the formulations, nylon has good compatibility after processing, and the obtained nylon 6 composite material has excellent mechanical properties and flame retardancy, but the above-mentioned nano-modification process cannot really solve the problem of nano-particle dispersion , and the preparation process of blow-molded nylon is complicated in actual production, and various additives need to be added to meet different needs
