Abstract

Disclosed is a method of producing organic glass with high wear resistance and high impact resistance by film transferring. Methyl methacrylate prepolymer, pentaerythritol tris-acrylate, dipentaerythritol acrylate, trimethylolpropane tris-acrylate, noepentyl glycol diacrylate, polyethylene glycol (200, 400, 600) diacrylate, hexanediol diacrylate, photosensitizer, flow agent and defoaming agent are sprayed on a toughened glass template to be uv-cured to functional film. The toughened glass with the functional film is used as a template to make the organic glass with wear resistance and impact resistance according to the conventional preparation process with polymethyl methacrylate being injected into the template. The organic glass sheet has the advantages of enough surface hardness and surface resistance, fine impact resistance, antistatic effect and light transmittance, and obvious wear absorption and low moisture resistance compared with the common organic glass.

Description

technical field [0001] The present invention relates to a method for preparing organic glass plates, in particular to a method for preparing high wear-resistant and high-impact organic glass by film transfer method, which includes the transfer of wear-resistant layer functional film, the formula of wear-resistant coating, Spraying technology for UV curing and wear-resistant layers. Background technique [0002] The preparation method of ordinary plexiglass is: use two pieces of inorganic toughened glass as a template, add a prepolymer of methyl methacrylate to the film plate, polymerize for about several hours at 45-50 °C water temperature, and then pass through 100-125 °C Ordinary plexiglass is obtained after left and right high temperature for about several hours. The surface hardness of this ordinary plexiglass is only 2 to 3H (pencil hardness), and the surface resistance is very large, which is easy to generate static electricity. The surface hardness of the wear-resis...
