Problems solved by technology

[0002] Due to the particularity of the production environment of pharmaceutical companies, the staff in the clean area need to clean, sterilize and disinfect protective goggles every time they wear them. This method is likely to cause a chemical reaction to the goggles, resulting in deformation or even damage to the goggles. Production areas present safety risks
At present, most of the main protective goggles on the market are made of ordinary plastic materials that cannot be cleaned and sterilized by high temperature. In addition, after the materials used in some protective goggles on the market are subjected to high-temperature cleaning and damp heat sterilization, the service life is severely shortened, resulting in frequent replacement of scrapped goggles. Waste of resources and manpower and material resources, but also increased environmental pollution

Abstract

The invention provides a protective eyeshade with a cleaning-resistant, high-temperature-resistant, damp-heat-resistant and sterilizing composition. The protective eyeshade comprises a protective lens, an eyeshade frame and a fixing part. The protective lens is embedded into the eyeshade frame, the eyeshade frame and a woven tape are fixed together through the fixing part, the protective lens is composed of a modified polycarbonate composition, and the modified polycarbonate composition comprises polycarbonate, high-temperature-resistant resin, a compatilizer, an antioxidant, a flame retardantand an antibacterial agent. The eyeshade frame and the fixing part are both composed of a modified thermoplastic vulcanized rubber composition. The modified thermoplastic vulcanized rubber composition comprises thermoplastic vulcanized rubber, a flexibilizer, a vulcanizing agent and an anti-aging agent. The protective eyeshade is prepared from the modified polycarbonate composition and the modified thermoplastic vulcanized rubber composition so that the protective eyeshade has the characteristics of high temperature resistance, cleaning resistance, good impact resistance, high strength, goodantibacterial property, good flame retardant property, aging resistance and the like, has good elasticity and compression deformation resistance and can be repeatedly used.
