Antistatic waterproof modified nylon 12 material for automobile plastic part

Abstract

The invention belongs to the field of high polymer materials, and particularly relates to an antistatic waterproof modified nylon 12 material for an automobile plastic part. The material is prepared from the following raw materials in parts by weight: 100 parts of nylon 12, 7-9 parts of diethyl terephthalate, 15-18 parts of high-density polyethylene, 7-9 parts of ultrafine talcum powder, 3-4 parts of diaminodiphenylmethane, 2-3 parts of diammonium hydrogen phosphate, 6-8 parts of borax, 5-8 parts of rutile titanium white, 1-2 parts of hydrophobic silicon dioxide, 1.6-1.8 parts of antioxidant DSTP, 2-3 parts of stearic acid, 4-6 parts of dibutyl phthalate and 12-15 parts of assistant. According to the invention, the modified nylon 12 material combines the advantages of the raw materials such as the nylon 12, the high-density polyethylene and the like, and improves the performance of the traditional nylon 12 material. Besides, the raw materials such as the rutile titanium white, the hydrophobic silicon dioxide and the like are added, so that the prepared material is high in hardness, waterproof, dampproof, favorable in electric property, antistatic, heat-resistant, light-resistant and long in service life, and can be widely used in manufacturing of various automobile plastic parts.

[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
