Special composite material for nylon composite plastic automobile and preparation method of special composite material

The invention relates to the technical field of nylon composite materials, in particular to a special composite material for a nylon composite plastic automobile and a preparation method of the special composite material. The composite material comprises the following raw materials in parts by weight: 40-60 parts of a nylon material, 15-19 parts of a modified material, 5-20 parts of a fiber material, 12-17 parts of a filler and 1-5 parts of a silane coupling agent, according to the invention, the added modified material is blended with the nylon material, so that the high-temperature performance and strength of the composite material can be provided; when an automobile runs at a high temperature or has a traffic accident, the high-strength high-temperature resistance of the composite material can well protect internal elements, and damage caused by heat or further dangerous conditions are prevented; and secondly, when the automobile is subjected to emergency situations such as collision, the composite materia
