Photo-thermocuring organic silicon LOCA (liquid optical clear adhesive) as well as preparation method and application of photo-thermocuring organic silicon LOCA

The invention discloses a photo-thermocuring organic silicon LOCA (liquid optical clear adhesive) as well as a preparation method and application thereof. Comprising a component A and a component B, the component A comprises 75-85% of vinyl silicone oil, 3-5% of sulfydryl silicone oil, 5-8% of hydrogen-based silicone oil, 0-5% of a silane coupling agent and 0-2% of a defoaming agent; and the component B comprises 45-55% of platinum silicone oil, 45-50% of free radical photoinitiator silicone oil and 0.5-3% of dispersing agent. The filling glue is based on the vehicle-mounted display screen, not only has good weather resistance and heat resistance of silica gel, but also has the advantages of no generation of by-products in the vulcanization process, small shrinkage rate, deep curing, no corrosion to contacted materials, safe and environment-friendly production process, short forming period, good strength of finished products, transparency, odorlessness and easiness in meeting of flow line production requireme
