Nylon composite material with stable and compatible glass fibers and preparation method of nylon composite material

The invention provides a nylon composite material with stable and compatible glass fibers and a preparation method of the nylon composite material. The silane coupling agent and the acrylate are polymerized to modify the glass fiber, the surface of the glass fiber is coated with the modified organic silicon layer, and the organic silicon layer is beneficial to increasing the compatibility of the glass fiber in a nylon system; the glass fiber with higher specific gravity can be added into the nylon composite material without influencing the mechanical property of the composite material, and meanwhile, the heat resistance is improved. The modified glass fibers are compounded with various commercially available nylon materials, semi-aromatic nylon polymers, antioxidants, silicone plastic additives and the like, and the obtained nylon composite material has the characteristics of more excellent thermal deformation temperature, tensile strength, bending strength and the like, and has a wide application prospect. 本
