Abstract

The invention discloses a preparation method of a nylon composite material. The preparation method of the nylon composite material comprises the following steps: adding nylon PA66, epoxy resin E-51, maleic anhydride elastomer and polyvinyl alcohol in a high-speed mixing machine; and dropwise adding dibutyltin dilaurate and chlorinated paraffin, mixing, adding a succinic anhydride compound and a coupling agent KH550, continuing stirring, adding medium-alkali glass fibers, magnesium hydroxide, aluminium hydroxide, ammonium polyphosphate, oxidation inhibitor and a lubricant, continuing stirring, then adding the material in a double-screw extruder, mixing evenly, carrying out melt extrusion, and cooling to obtain the nylon composite material. By the preparation method of the nylon composite material, the obtained nylon composite material has strengthened rigidity and hardness, the heat resistance, the size stability and the ageing property are excellent, and the nylon composite material is suitable for blow molding, and can meet requirements of various structural components such as automobiles, instruments and apparatuses and electronic and electrical products to high performance.

Description

technical field [0001] The invention relates to the technical field of nylon, in particular to a preparation method of a nylon composite material. Background technique [0002] As the largest and most important variety of engineering plastics, nylon has strong vitality, mainly because it has excellent mechanical properties, high strength, high rigidity, wear resistance, and excellent chemical resistance, oil resistance, and alkali resistance. After modification, it can achieve high performance, so it is widely used in automobiles, electrical equipment, mechanical parts, transportation equipment, textiles, and papermaking machinery. But it also has some disadvantages, such as poor thermal stability and impact resistance needs to be improved. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a method for preparing a nylon composite material. The obtained nylon composite material has enhanced rigid...
