Abstract

The invention discloses a wear-resistant resin lens and a preparation method thereof. The lens comprises a PMMA chip and wear-resistant layers adhered to two surfaces of the PMMA chip directly or indirectly, wherein the PMMA chip comprises the following raw materials in parts by weight: 100 parts of PMMA resin, 10-20 parts of polycarbonate, 10-15 parts of polystyrene resin, 3-8 parts of polypropylene glycol, 0.5-5 parts of initiator, 0.5-1.5 parts of sodium cocoly lactate and 1-3 parts of ultraviolet light absorber. The preparation method comprises the following steps: (1) weighing raw materials for preparing the PMMA chip in parts by weight, adding into a mixing kettle, thermally stirring for 30-40 minutes, cooling to room temperature, extruding the chip in a twin-screw extruder; and (2)putting the PMMA chip into a vacuum evaporator, and vacuumizing; uniformly bombarding a nano-material by utilizing an electronic gun when the vacuum degree is reached until the material is evaporatedat the melting point, and coating to form a nano-film; and evaporating again to complete two sides of evaporation. According to the wear-resistant resin lens, the lens chip surface is coated, the wearresistance of glasses can be improved, and the service life of the glasses can be prolonged.

Description

technical field [0001] The invention relates to the technical field of glasses, in particular to a wear-resistant resin lens and a preparation method thereof. Background technique [0002] Glasses have greatly improved and improved human life. At first, inorganic substances were used as materials for eyeglass lenses. Later, people developed transparent plastics with light weight and good optical properties. However, the existence of transparent plastics is prone to stress cracking and fatigue resistance. The disadvantages of poor chemical stability and low surface hardness affect its wide application. The main means used to solve this problem is to add a hard film on the lens to improve the wear resistance of the surface, solve the damage caused by scratches and prolong the service life of the lens. During use, the wearer of the glasses will wear them for a long time except for special circumstances such as sleeping and bathing. They often use glasses cloth or paper towels ...
