Problems solved by technology

[0002] The existing welding protective lenses used on welding masks have always used transparent colorless glass as the preferred manufacturing material, which has the defects of low product safety performance, poor high temperature resistance and transmittance performance, and short service life, which brings great difficulties to electric welders. very serious bodily harm
In recent years, all parts of the world are gradually trying to replace glass with resin and other materials, and a large number of resin lenses have appeared. However, due to the defects of material selection, there are poor product safety, low light transmittance, no anti-oxidation and high temperature, no anti-static , poor wear resistance and other defects

Abstract

The invention relates to a CR-39 electric welding protective lens with the function of high wearing quality, good transmittance and high shock resistance used on a welding mask, which is prepared by the following material according to parts by weight: 70-90 parts of polydiene propyl diglycol dicarbamate, 10-15 parts of methyl propyl methyl acetate, 0.5-1 part of ultraviolet absorbent UV-531, 0.03-0.05 part of polyurethane parting medium and 0.5-1.5 parts of IPP evocating agent. The lens has the advantages of high wearing quality, good transmittance and high shock resistance, high temperature resistance, uvioresistant, anti-infrared and electrostatic prevention.

Description

Technical field: [0001] The invention relates to a CR-39 electric welding protective lens used on an electric welding mask with strong wear resistance, good light transmittance and strong impact resistance. Background technique: [0002] The existing welding protective lenses used on welding masks have always used transparent colorless glass as the preferred manufacturing material, which has the defects of low product safety performance, poor high temperature resistance and transmittance performance, and short service life, which brings great difficulties to electric welders. There came a very great bodily injury. In recent years, all parts of the world are gradually trying to replace glass with resin and other materials, and a large number of resin lenses have appeared. However, due to the defects of material selection, there are poor product safety, low light transmittance, no anti-oxidation and high temperature, no anti-static , poor wear resistance and other defects.
