Abstract

The invention relates to a preparation method of a solvent-free photocuring material. The preparation method includes adding 120 g of double-carbon hydroxyl silicone oil and 17 g of isophorone diisocyanate into a reactor together, adding 0.1 g of dibutyltin dilaurate as a catalyst, reacting for 2.5-5 hours at 75 DEG C, adding 3.5 g of hydroxyethyl acrylate and 0.3 g of 4-methoxyphenol, continuing to react for 2-4 hours at 75 DEG C, adding 30 g of 2-ethylhexyl acrylate with stirring evenly, adding 5 g of 2-hydroxy-methyl-phenyl-propane-1-one as a photoinitiator, mixing to enable system viscosity to be kept at 2,000 mPa-S, applying a mixture on a PET (polyethylene terephthalate) film after even stirring, disposing the PET film 15 centimeters away from a 2 Kw ultraviolet lamp and under the same and curing the PET film for 50 seconds so as to obtain the solvent-free photocuring material.

Description

technical field [0001] The invention relates to the preparation of a solvent-free light-curing material, belonging to the field of synthetic chemistry. Background technique [0002] Silicone pressure-sensitive adhesives are a kind of high-quality special pressure-sensitive adhesives in pressure-sensitive adhesives. The current silicone pressure-sensitive adhesives, such as silanol condensation type silicone pressure-sensitive adhesives, are suitable for silicone pressure-sensitive adhesives used under high temperature and harsh conditions. glue system. This pressure-sensitive adhesive is usually composed of silicone rubber, MQ silicone resin, organic solvents and other additives. The organic solvent used is generally toluene or xylene, and a large amount of volatile organic compounds (VOC) are excluded during the coating process. These substances not only cause serious environmental pollution, but also pose a threat to human health. Contents of the invention [0003] Th...
