Problems solved by technology

[0003] With the continuous development of light-curing technology, more and more functional materials are combined into light-curing formulations. For example, antistatic light-curing coating systems use quaternary ammonium salts as moisturizing and antistatic agents, but quaternary ammonium salts are used in traditional light-curing It is basically dissolved in the formula, and it is difficult to disperse. It is necessary to use highly polar solvents to aid dissolution, such as DMSO, DMF, sulfolane, etc. contrary to the characteristics of
Moreover, the above-mentioned highly polar solvents do not participate in photo-crosslinking film formation, and most of them have low volatility, and may permeate and migrate if they remain in the photo-cured coating, which will affect the performance of the cured film.

Abstract

The invention discloses an acrylate compound containing a methyl sulfoxide structure. The compound has a structural formula as represented by formula (I). A preparation method for the acrylate compound containing a methyl sulfoxide structure is characterized in that 2-methylthioethyl (methyl) acrylate is used as a raw material and subjected to oxidation under the action of such decomposition accelerators as hydrogen peroxide and cupric hydrogen peroxide so as to prepare the acrylate compound. The acrylate compound containing a methyl sulfoxide structure has both methyl sulfoxide groups and (methyl) acrylate groups, high molecular dipole moment and strong dissolvability and can participate in cationic polymerization or free radical polymerization to improve intersolubility of structures of all the components in a cured coating.

Description

technical field [0001] The invention belongs to the field of organic synthesis, and in particular relates to an acrylate compound containing a methyl sulfoxide structure and a preparation method and application thereof. Background technique [0002] Acrylate compounds are widely used in polymer material synthesis or light-curing formulation systems because of their high-efficiency polymerizability. Small-molecular-weight acrylates are often used as reactive diluent monomers for light-curing coatings, inks, and adhesives. At the same time, because acrylate monomers generally undergo rapid free radical polymerization, acrylate monomers are often used in free radical photocurable formulations. At present, commonly used acrylate monomers are generally prepared based on simple alcohols or ether alcohol raw materials. In addition to acrylate groups, the commonly used acrylate monomer structures usually do not have other special functional groups, making acrylate monomers The over...
