Filter lens for electric welding and method for manufacturing filter lens for electric welding

Abstract

The invention discloses a filter lens for electric welding and a method for manufacturing the filter lens for electric welding. The lens is made of resin lens materials, iron oxide particles of core-shell structures, titanium oxide particles of core-shell structures, and copper oxide nano particles of core-shell structures, wherein the iron oxide particles, the titanium oxide particles and the copper oxide nano particles are scattered in the resin lens materials, the overall weight of the nano particles is 0.5%-3.5% of the overall weight of the resin lens materials, the weight ratio of the iron oxide particles to the titanium oxide particles and the copper oxide nano particles is 1.8-2.1:1.8-2.1:0.9-1.1, the inner cores of the nano particles are made of iron oxide, titanium oxide and copper oxide, the particle sizes of the nano particles are 10 nm-50 nm, a shell is a surface finishing agent or a surface modification agent, and the thickness of the shell is 3 nm-10 nm. By the adoption of the filter lens, a workpiece can be clearly seen before arcing, harmful hard light can be filtered out after arcing, and eyes are protected.

Description

technical field [0001] The invention relates to an eye protection filter lens for electric welding, in particular to a functional resin filter produced by compounding polymer resin and nano particles. Background technique [0002] Optical filter is an optical material, which is an optical device used to intercept or selectively filter certain wavelength bands of light. It can attenuate light intensity and change light composition. It is usually made of plastic sheet or glass sheet and added with special dyes. As a window material for various equipment or equipment. Most of the welding protective filter lenses used in daily use are glass crystal structure lenses. Due to the low transmittance of the glass lens, the welding operator cannot see the welded workpiece at all before starting welding. During the welding process, the vision is also blurred, which affects welding Quality and speed, especially in special workplaces with weak light or workpieces with high welding precis...

Problems solved by technology

Most of the welding protective filter lenses used in daily use are glass crystal structure lenses. Due to the low transmittance of the glass lens, the welding operator cannot see the welded workpiece at all before starting welding. During the welding process, the vision is also blurred, which affects welding Quality and speed, especially in special workplaces with weak light or workpieces with high welding precision requirements, have a greater impact

The main reason is that the existing electric welding protective lens also affects the passage of harmless light while filtering harmful strong light, especially in special places with weak light, because the transmittance of the lens in the visible light area is too low, resulting in visual loss.
