Description
Technical Field
The invention relates to the technical field of high molecular materials, in particular to a preparation method of a high-impact-resistance liquid crystal polymer composite material.
Background
Liquid Crystal Polymers (LCP) are intermediate polymers between solid and liquid crystals, and their molecular arrangement is not three-dimensionally ordered as in solid crystals, but rather is not disordered as in liquid crystals, but rather has some ordering. It is a novel polymer material which generally exhibits liquid crystallinity in a molten state. LCP has good high-temperature performance, good radiation resistance, hydrolysis resistance, weather resistance, chemical resistance, inherent flame retardance and the like, so that the LCP has wide application prospect in the fields of electronics, electricity, optical fibers, automobiles, aerospace and the like. However, LCP is also very defective, and because of its unique properties, its crystal formation is oriented along the weld line, resulting in brittleness of thin-walled molded articles, and thus modification of LCP is the main means for obtaining high-performance and multifunctional materials.
Currently, there are generally two methods to modify polymers: chemical modification and physical modification, wherein the chemical modification mainly changes the molecular structure by chemical means such as copolymerization, grafting, crosslinking and the like so as to improve the strength, toughness and other properties of the material; the physical modification is to improve the performance of the material by melt blending and filling; compared with the chemical modification method, the physical modification method is simple to operate, economical and feasible, and therefore has attracted extensive attention. At present, physical modification methods for improving impact strength are mainly divided into elastomer modification, rigid particle modification, core-shell structure polymer modification, liquid modification and the like. However, these modification methods usually cannot improve the impact strength of the composite material while ensuring the flame retardant property of the composite material, so that the modified composite material still cannot meet the application requirements of higher requirements.
