Abstract: The present disclosure relates to the field of silica gel, and discloses a liquid optical silica gel composition, optical silica gel, a double-glazed photovoltaic assembly and a fabrication method of the optical silica gel. The present disclosure discloses a liquid optical silica gel composition. The composition contains vinyl silicone oil, hydrogen-containing silicone oil, hydrogen-containing MQ silicone resin, a catalyst, an inhibitor and a tackifier. The weight ratio between the vinyl silicone oil, the hydrogen-containing silicone oil, the hydrogen-containing MQ silicone resin and the tackifier is 1:(0.001-0.1):(0.0001-0.08):(0.001-0.05). The hydrogen-containing silicone oil contains first hydrogen-containing silicone oil and second hydrogen-containing silicone oil. The first hydrogen-containing silicone oil has a hydrogen content of 0.1 to 1 percent by weight. The second hydrogen-containing silicone oil has a hydrogen content of 0.01 to 0.1 percent by weight.

Abstract: The present disclosure discloses an anti-yellowing composition comprising at least a phosphorus-containing compound and at least a pentaerythritol ester, wherein the phosphorus-containing compound is selected from a phosphate salt, and a concentration of the phosphorus-containing compound is 100-1600 parts by weight, relative to 100 parts by weight of the pentaerythritol ester. The present disclosure also discloses a resin composition containing the anti-yellowing composition, and a metal-resin composite formed with the resin composition and a metal substrate, and a preparation method and use thereof. The present disclosure further discloses an electronic product shell formed with the resin composition and a metal shell body.
