Abstract

The invention relates to a high polymer material, particularly a silica gel liquid crystal display adhesive and an application method thereof. The silica gel liquid crystal display adhesive is a double-component liquid silica gel comprising a component A sizing material and a component B sizing material. The component A sizing material is composed of the following components in parts by weight: 60-80 parts of phenylpropenyl silicon resin containing M and Q chain links, 20-40 parts of phenylpropenyl silicon oil containing M and Q chain links and 0.06-0.1 part of catalyst. The component B sizing material is composed of the following components in parts by weight: 60-80 parts of phenylpropenyl silicon resin containing M and Q chain links, 20-40 parts of phenylpropenyl silicon oil containing M and Q chain links, 2-3 parts of hydrogen-containing silicon oil containing M and Q chain links, 0.3-0.5 part of epoxy tackifier and 0.1-0.5 part of addition reaction inhibitor. The silica gel liquid crystal display adhesive has the characteristics of high temperature resistance, acid / alkali resistance, high adhesion property, high mechanical strength of elastomer and high light transmittance, and can firmly bond liquid crystal displays and glass.

Description

technical field [0001] The invention relates to a polymer material, in particular to a silicone liquid crystal screen adhesive and a using method thereof. Background technique [0002] Since most of the high-tech fields such as electronic components, power circuit modules, and large integrated circuit boards of modern LCD devices have further achieved high performance and high reliability, the quality requirements for silicone LCD screen adhesives are very high, such as thin coating , good light transmission, strong adhesion, good stability, easy to transport and store, for defective products that appear in the production process can be cleaned in a very simple way to recycle the LCD screen, and so on. At present, such products are in great demand in China, but they have not yet been localized, and they are completely dependent on imports, which are expensive. Contents of the invention [0003] The object of the present invention is to provide a silicone liquid crystal sc...
