Abstract

The invention discloses a high-strength multifunctional composite electric control tube for a sedan and a preparation method of the electric control tube. The high-strength multifunctional composite electric control tube raw material is prepared from engineering plastics as a main raw material by addition of reasonable materials and melt mixing, and solves the problems of low strength and poor toughness of the high-strength multifunctional composite electric control tube material for the existing sedan. By adding an additive, the compatibility of high-performance resin cyanate ester and bismaleimide resin with alkene is improved, a material system reacts step by step by means of design of a forming process, and the problem of material defects caused by too fast local reaction is solved; the high-strength multifunctional composite electric control tube for the sedan has excellent extensibility, high strength and good heat resistance, has higher toughness than the high-strength multifunctional composite electric control tube for the existing sedan and is beneficial to industrialized application.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a high-strength multifunctional composite electrical control tube for cars and a preparation method thereof. Background technique [0002] In recent years, engineering plastics have been widely used in electronics, automobiles and other industries. Substituting plastic for steel and plastic for wood has become an international trend. These engineering plastic parts are used as automotive interior pipes, which need to have high strength and impact resistance. While plastics increase in strength, their flexibility and impact resistance decrease. Although some people have used the method of material modification to solve this problem, it is not easy to coordinate due to the contradictions between some physical and chemical properties. Contents of the invention [0003] The object of the present invention is to provide a high-strength multifunctional composite elect...
