Title:
METHOD FOR PREPARING ULTRAVIOLET (UV) CURING POLYMETHYLSILOXANE CONTAINING ACRYLATE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2019/205802
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing an ultraviolet (UV) curing polymethyl siloxane containing an acrylate structure: performing a Michael addition reaction with an amino silicone oil by means of an asymmetric diene acrylate ethylene glycol methacrylate, the double bond of asymmetric diene having a large difference in activity, and the acrylate structure preferentially undergoing addition with an amino group; thus, a methacrylic structure is successfully linked to a side chain of the methyl silicone oil, and a methyl silicone oil having a controllable structure and having a side group containing the methacrylate structure is prepared, the reaction having a high grafting rate; the described method is a high-efficiency, mild and controllable preparation method; a conventional compound photoinitiator is selected, and is coated on a substrate for UV curing, quickly curing at room temperature to form a film, and having the features of being clean and pollution-free, while not requiring a silicone oil-modified photoinitiator be complicatedly prepared; an organosilicone is prepared and has the advantages of high temperature resistance, good weather resistance, good electrical insulation, an excellent release effect, low surface tension and so on, being widely applied in the industries such as release coating, coating, leather additives and packaging.
