Description

technical field [0001] The invention relates to a goggle lens and a preparation method thereof, in particular to a heat-resistant and wear-resistant propylene glycol carbonate resin flat goggle lens (CR-39 resin goggle lens) and a preparation method. Background technique [0002] For the welding shield, the commonly used lens is made of glass, and the protective ability of the lens is acceptable, but when the operator observes the welding condition with his eyes, he must remove the welding shield from the line of sight, which is very inconvenient. After being used for a period of time, the glass lens will stick to slag, which affects the line of sight and causes the cost of changing the lens. In addition, glass lenses have low hardness and are easily broken. Later, liquid crystal lenses appeared. When there was no welding arc, the lens was transparent, and when there was arc, the lens turned black, and the response time was 0.1-0.2 seconds. However, due to the limited prom...
