Basalt reinforced LCP composite material and preparation process thereof

Abstract

The invention relates to the field of novel plastic materials, in particular to a basalt reinforced LCP (liquid crystal polymer) composite material and a preparation method thereof. The basalt reinforced LCP composite material comprises the following component in parts by weight: 40-80 parts of LCP, 12-30 parts of basalt fiber, 0.3-0.9 part of a heat-resistant agent, 3-9 parts of a coupling agent, 3-6 parts of a main antioxidant, 1-3 parts of an auxiliary antioxidant, 1-5 parts of a compatilizer, 0.5-2 parts of a lubricant, 2-6 parts of a flame retardant, and 1-3 parts of a flame retardant synergist, wherein the heat-resistant agent is N,N'-4,4'-diphenylmethane dimalephthalamide. The basalt reinforced LCP composite material provided by the invention is high in mechanical strength, good in heat resistance and wide in application range.

Description

technical field [0001] The invention relates to the field of new plastic materials, in particular to a basalt reinforced LCP composite material and a preparation process thereof. Background technique [0002] Liquid Crystal Polymer (LCP for short) is a class of polymers with special properties discovered in the 1950s. LCP is an intermediate state polymer between solid crystal and liquid. Although its molecular arrangement is not as three-dimensional as solid crystal, it is not as disordered as liquid, but has a certain (one-dimensional or two-dimensional) Orderliness. It is a new type of polymer material, which generally exhibits liquid crystallinity in the molten state. [0003] Due to the excellent mechanical properties, heat resistance and chemical stability of LCP, it has very broad application prospects. Although the period from development to application of LCP is very short, it has already played an important role as a class of structural materials in electrical co...

Problems solved by technology

[0004] However, in the field of automobiles, due to the high requirements of heat resistance, thermal conductivity and mechanical strength of materials for auto parts, the performance of the unmodified LCP materials in the prior art still needs to be further improved, such as thermal The deformation temperature is as high as 350°C, which is significantly higher than most thermoplastics, but the temperature of some precision parts in the car is as high as 400°C, which limits the application of LCP materials in the automotive field
