High-refractive-index methacryloyloxy-containing organic silicon tackifier as well as preparation method and application thereof

The invention discloses a methacryloyloxy-containing organic silicon tackifier with a high refractive index as well as a preparation method and application of the methacryloyloxy-containing organic silicon tackifier. The characteristics that polar groups such as hydroxyl on the surface of the copper base material can chemically react with methacryloyloxy, and the methacryloyloxy can react with silicon hydrogen groups in the liquid silicone rubber are utilized; the organic silicon tackifier capable of effectively enhancing the bonding strength of silicon rubber and a copper base material is prepared by taking hydroxyl-terminated silicone oil with active groups, alkoxy silane containing vinyl and alkoxy silane containing methacryloyloxy as raw materials. The tackifier can be used for addition type organic silicon rubber with high refractive index, has good compatibility with silicon rubber, has little influence on the light transmittance and mechanical properties of the silicon rubber, and does not have a catal
