Toughening oil-resistant modified nylon material for automobile plastic members

Abstract

The invention belongs to the field of high-molecular materials, and specifically relates to a toughening oil-resistant modified nylon material for automobile plastic members. The material is prepared from the following raw materials in parts by weight: 100 parts of nylon 12, 30-34 parts of high density polyethylene, 12-14 parts of maleic anhydride grafted polyethylene, 9-12 parts of aluminium hydroxide, 4-6 parts of magnesium hydroxide, 8-10 parts of kaolin, 4-5 parts of Brazilian palm wax, 3-4 parts of zinc oxide, 1-2 parts of alga polysaccharide, 1-2 parts of carboxymethyl cellulose, 2-3 parts of ferrous sulphate, 4-6 aprts of polyacrylamide, 8-10 parts of triolein, 1-2 parts of sodium laurylsulfate and 12-15 parts of an auxiliary agent. The material combines the advantages of the raw materials such as nylon 12, high density polyethylene, maleic anhydride grafted polyethylene and the like; and the prepared material is pliable, tough, resistant to high-temperature and low-temperature ageing, resistant to oil penetration, resistant to corrosion, flame-retardant, firm and durable, is widely applicable to prepare various automobile plastic members, and is especially applicable to prepare plastic members for automobile fuel tank shells, petroleum pipes and the like.

[0002] With the development of the automobile industry, people have higher and higher requirements for the performance of automobiles such as comfort, safety, aesthetics, and energy saving. The improvement of traditional automobile materials is the fundamental way to improve the performance of automobiles. Polymer Compared with traditional automotive materials, automotive plastic materials have many outstanding advantages, such as light weight, superior mechanical properties, easy processing and molding, reusable materials, and excellent aesthetic and decorative effects. However, these polymer materials also have some disadvantages, such as rigidity. Poor, easy to burn, not resistant to high temperature and low temperature aging, etc. Therefore, in order to improve the performance of traditional polymer materials and broaden the scope of use of materials, it is necessary to improve the original automotive plastic formula and modify the material so that it can be widely used Applied to various parts of the car
