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. |
