The invention discloses a strong elastic phenyl silicone resin for LED lenses and a preparation method thereof. The strong elastic phenyl silicone resin for LED lenses comprises, by weight percentage, 100-120 parts of vinyl phenyl silicone resin, 100-150 parts of vinyl phenyl silicone oil, 30-60 parts of hydrogen-containing methyl phenyl silicone resin, 0.05-0.3 part of a catalyst, 0.05-0.3 part of an inhibitor, and 0.1-1.0 part of a reinforcing agent. The preparation method comprises vinyl phenyl silicone resin preparation, hydrogen-containing silicone resin preparation and preparation of the strong elastic phenyl silicone resin for LED lenses. The obtained final curing product of the strong elastic phenyl silicone resin for LED lens has high transparency. Resin with Linear and network crosslinking structure and reinforcing agent endow the wallpaper with good hardness, tensile strength and elongation at break. The preparation method of the invention is simple, and the strong elastic phenyl silicone resin for LED lenses has good mechanical properties. |
