Abstract

The heat-curing anti-yellowing full-fit special material provided by the present invention comprises the following components in parts by weight: Component A: 50-100 parts of vinyl silicone oil at 500-1000mPa.s; 2000-5000mPa.s 20-50 parts of vinyl-terminated silicone oil; 0.001-0.05 parts of platinum catalyst; 1-2 parts of ultraviolet light stabilizer; The hydrogen content is 0.01-0.02% terminal hydrogen-containing silicone oil 10-30 parts; the hydrogen content is 0.1-0.2% terminal hydrogen-containing silicone oil 10-30 parts; the hydrogen content is 0.3-1.6% terminal hydrogen-containing silicone oil 1-6 parts; 10-20 parts of vinyl MQ silicone resin. The heat-curing anti-yellowing anti-yellowing material provided by the present invention is used and added with vinyl MQ silicone resin, which can obviously inhibit the yellowing problem caused by the reduction of the catalyst, so it has good anti-macular performance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a heat-curing anti-yellowing fully laminating special material and a preparation method and application thereof. Background technique [0002] At present, the special materials for full bonding of displays mainly include OCA glue, UV light-curing glue and thermosetting silicone. The phenolic substances in traditional OCA adhesives are prone to oxidation reactions, forming quinones and quinone polymers, which make OCA adhesives yellow, which in turn affects the light transmission of optical adhesives and even optical adhesive films; while in UV light-curable adhesives, If there is a substituent such as N-methylamino in the conjugated structure of the photoinitiator, the tendency of irradiation yellowing is generally higher. In the organic silicone adhesive, since the platinum metal catalyst is easily reduced to generate zero-valent platinum, the generated platinum black...
