Abstract

The invention relates to a hollow micro-sphere reinforced nylon plate material and a preparation process thereof. The hollow micro-sphere reinforced nylon plate material comprises a plate material body which is made of nylon resin, wherein anti-abrasion layers which are made of hollow micro-spheres respectively cover the upper and lower surfaces of the plate material body; and the plate material body and the anti-abrasion layers have an integrated structure. The preparation process comprises 1) hollow micro-sphere modification, 2) heating and melting, 3) dehydration, 4) charging and 5) rolling. The hollow micro-sphere reinforced nylon plate material is reasonable in structural design; the anti-abrasion layers which are made of the hollow micro-spheres respectively cover the upper and lower surfaces of the plate material body, so floating fibers can be prevented from being exposed, the surface smoothness of a product is improved, and flowing performance is improved; the hollow micro-sphere reinforced nylon plate material is convenient to process; and shrinkage deformation rate can be effectively reduced, the phenomenon of back warping of the product is eliminated, and the high temperature resistance, abrasion resistance and scratching resistance of the product are improved.

Description

technical field [0001] The invention relates to a nylon plate and its preparation process, in particular to a hollow microbead reinforced nylon plate and its preparation process. Background technique [0002] Hollow microspheres are a loose, fluid powder material. The characteristics of hollow glass microspheres are: sound insulation, flame retardancy, good electrical insulation, low density, low oil absorption, and high strength. They are widely used in inks, adhesives, engineering plastics, modified rubber, and electrical insulation. Because of its stable performance, good weather resistance and low price, it has been widely used. [0003] Nylon resin has a low melting point, strong impact resistance, solubility resistance, and strong hygroscopicity. It is widely used in machine tools, automobiles, machinery, and chemical industries, and is suitable for making various types of parts. [0004] At present, there is no material combining hollow microspheres and nylon resin,...
