[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

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 CrystalPolymer (LCP for short) is a class of polymers with special properties discovered in the 1950s. LCP is an intermediate statepolymer between solidcrystal and liquid. Although its molecular arrangement is not as three-dimensional as solidcrystal, 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...
