High-strength wear-resistant high-transmission polycarbonate film

Abstract

The invention relates to the field of polycarbonate resin, in particular relates to a high-strength wear-resistant high-transmission polycarbonate film. The high-strength wear-resistant high-transmission polycarbonate film comprises a base material made from polycarbonate, wherein the base material is a sheet or a film with the thickness of 0.025-25mm, a layer of nano silicon dioxide dried and cured by ultraviolet rays is sprayed on at least one of an upper surface and a lower surface of the sheet or film, the average spraying thickness of the single surface is 1-100mum, the viscosity of the nano silicon dioxide is 18-38MPa.s, the split particles with particle size distribution of 0.1-0.5mum are more than 99%, and the specific surface area is 25-100m<2> / g. According to invention, the high-strength wear-resistant high-transmission polycarbonate film is sprayed on the surface of the polycarbonate, and one layer of nano silicon dioxide is dried and cured by ultraviolet rays, so that on the premise that the transmission of the film is not influenced, the strength and tensile ductility of the film can be improved, the wear resistance and finishing can be enhanced, the applications of the film are wide. Thus, the high-strength wear-resistant high-transmission polycarbonate film is a novel environment-friendly multifunctional film.

Description

technical field [0001] The invention relates to the field of polycarbonate resins, in particular to a high-strength wear-resistant polycarbonate resin. Background technique [0002] Polycarbonate PC is one of the five widely used engineering plastics. It has comprehensive and balanced mechanical, electrical and heat resistance properties. It is especially famous for its excellent impact strength and creep resistance. It has high light transmittance and good mechanical properties. Impact toughness is the best among engineering plastics. Due to the excellent performance of PC, its products and its blended materials have been widely used in industries such as electronics, electrical appliances, machinery, automobiles, textiles, light industry and construction. [0003] Ordinary polycarbonate films have insufficient hydrolytic stability, are sensitive to notches, have poor resistance to organic chemicals, and have poor scratch resistance, which limits their application range. ...

Problems solved by technology

[0003] Ordinary polycarbonate film is not high enough in hydrolysis stability, sensitive to notch, organic chemical resistance, poor scratch resistance, which limits its application range

Nowadays, various additives and modification methods are usually added to the film to improve the above properties of the film. Although this can improve the hydrolytic stability and scratch resistance of the film to a certain extent, it often reduces the optical properties of the film. The light transmittance of the film is very low, which affects the normal use of the film

[0004] Japan Asahi Glass Co., Ltd. has designed a film made of glass fiber, which has the characteristics of both transparency and high strength. However, due to the actual process technology and cost, this film has not yet been mass-produced; Polycarbonate films with high strength, hydrolytic stability, abrasion resistance and transparency have not been practically used at home and abroad so far.
