Methyl) acrylate compound containing ketone carbonyl group as well as preparation method and application thereof

The invention discloses a (methyl) acrylate compound containing a ketone carbonyl group. The (methyl) acrylate compound containing the ketone carbonyl group is shown as a formula (I), wherein R1 and R2 are independently selected from H or CH3. A preparation method of the (methyl) acrylate compound containing the ketone carbonyl group comprises the following steps of: taking alpha-halogenated methyl ketone and (methyl) acrylate as raw materials and performing the replacement reaction on the raw materials in the presence of a phase transfer catalyst and an oily organic solvent to obtain the (methyl) acrylate compound containing the ketone carbonyl group, wherein the phase transfer catalyst is polyethylene glycol or a quaternary ammonium salt phase transfer catalyst. Compared with the conventional (methyl) acrylate diluting agent, functional inert resin which is added into the formula of the compound has the relatively good dissolving capability so as to improve the use ratio of the functional inert resin in the formula (inertia means that the functional inert resin is not subjected to chemical cross-linking reaction); the functional inert resin has obvious corrosion and bottom etching effects on the common plastic substrate; and the total result is that the self strength of a photo-curing material and the adhesiveness on the substrate are improved.
