▎ 摘 要
NOVELTY - Spectacle frame comprises 50-70 pts. wt. graphene, 40-60 pts. wt. styrene-butadiene block copolymer resin,10-20 pts. wt. silver chloride,10-15 pts. wt. plasticizer, 5-10 pts. wt. coupling agent, 1-5 pts. wt. inorganic pigment and 1-5 pts. wt. mint essential oil embedded in sodium alginate. The preparation of mint essential oil embedded in sodium alginate comprises taking sodium alginate, placing in a reactor, adding distilled water, heating to 40-50 degrees C in a water bath to obtain 15% sodium alginate solution in water with a constant temperature of 50 degrees C, slowly adding ethanol solution of mint essential oil to the sodium alginate aqueous solution while stirring , continuously stirring for 10-30 minutes, refrigerating suspension of formed inclusion complex for 24 hours, filtering, washing the inclusion with distilled water and freeze-drying to obtain dried mint essential oil embedded in white sodium alginate, where the ratio of the sodium alginate to the mint essential oil is (5-10): 1. USE - Used as spectacle frame comprising e.g. grapheme. ADVANTAGE - The spectacle frame has good mechanical property and flexibility.The method enhances the flame retardant ability and corrosion-proof antibacterial ability of the material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing spectacle frame comprising (a) mixing graphene, styrene-butadiene block copolymer resin, silver chloride, plasticizer, coupling agent and inorganic pigments, heating at 90-120 degrees C for 10-20 Hours, cooling to 60 degrees C, adding the essential oil embedded in sodium alginate to the mixture, stirring to obtain frame rubber material and (b) controlling the injection molding machine nozzle between 70-85 degrees C, adjusting the extrusion pressure to 1.5-2.0MPa, performing injection-molded of frame rubber obtained in step (a) into spectacle legs, spectacle frame and connector molds, heat preserving for 10-30 minutes, vulcanizing the rubber material, releasing the pressure to normal pressure after vulcanization, reducing the temperature to 10-20 degrees C for 2-5 hours to obtain perform, solidifying the perform after cooling and demolding to obtain a the finished products of the spectacle legs, spectacle frames and connector silicone products, where they are connected and assembled by metal screws and nuts to obtain a spectacle frame.
