Waterproof temperature-resistant modified nylon material for automobile plastic members

Abstract

The invention belongs to the field of high-molecular materials, and specifically relates to a waterproof temperature-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, 12-14 parts of chopped glass fibre, 5-6 parts of octadecanamide, 5-6 parts of ammonium polyphosphate, 12-14 parts of bentonite, 10-20 parts of dimethyl trimethylsilylmethylphosphonate, 30-50 parts of melamine cyanurate, 10-12 parts of antimonony oxide, 23-25 parts of polystyrene, 8-10 parts of montmorillonite, 5-6 parts of ricinoleic acid and 12-15 parts of an auxiliary agent. The material combines the advantages of the raw materials such as nylon 12, polystyrene and the like; and the prepared material is tough, pliable, high in hardness, ling in mass, low in water absorption rate, waterproof, moistureproof, resistant to low-temperature and high-temperature ageing, and safe and reliable to use, and is widely applicable to prepare various automobile plastic members, and is especially applicable to automobile members in environment with relatively high temperature or relatively high humidity.

[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
