Description

technical field [0001] The invention relates to peripheral products of LED lamps, in particular to a silica gel composition used for LED glass explosion-proof lampshades. Background technique [0002] LED light bulbs have the advantages of energy saving, environmental protection, and long life, so they have become a major trend in the lighting industry and are widely used in my country. At present, explosion-proof lampshades are used for explosion-proof LED bulbs. The material of explosion-proof lampshades for LED bulbs is generally PC or acrylic materials, but these two materials are expensive, and manufacturers need to bear higher cost pressures. The traditional glass lampshade is easy to break, and the splash of broken glass will cause unsafe factors. Therefore, the technology of coating a layer of silicone film on the outside of the glass lampshade was adopted to solve the problem of glass bursting. [0003] There are two types of silica gel commonly used for LED glass ...
