Problems solved by technology

[0002] Resin is the main raw material for the production of fine chemical products such as inks, adhesives, and coatings. Resin determines the performance, cost, and solvent dilution of these products; currently, most of the resins used to produce the above products are based on benzene, Diluted with ketone solvents, these solvents not only seriously pollute the environment, but also because they are petroleum refined products, with the rise of petroleum prices, the cost rises sharply; due to the pressure of cost and environmental protection, there are various systems in the market. Esters are resins used as solvents, wherein the applicant of the present invention describes a method of producing alcohol-soluble resins with vinyl acetate as the main raw material in another invention application "A kind of alcohol-soluble resin and its preparation method" (application number 200510021271. However, whether it is esters or alcohols, although their toxicity is lower than that of benzenes and ketones, they still belong to the scope of organic solvents. Resin as a solvent, that is, alcohol water-soluble resin or water-soluble resin, minimizes the amount of organic solvents, and becomes one of the goals pursued by the resin industry
There is no relevant report on the production of alcohol water-soluble resin by formula or process similar to the present invention

Abstract

The invention provides an alcohol water-soluble resin and a preparation method thereof. The alcohol water-soluble resin can be dissolved in the mixed solvent of alcohol and water and the polymerization raw materials of the alcohol water-soluble resin mainly consit of the vinyl acetate monomers, and simultaneously the methacrylate monomers, the acylid acids and other hydrophilic functional monomers are added into the raw materials so as to ensure that the performance of the resin can meet the requirements for particular use. The invention also provides an alcohol water-soluble ink, compound adhesive, antiseptic varnish for printing, gloss varnish for woodware, decorative coatings for plastic surface and hair colorants that are prepared by adotping resin and the preparation methods thereof.

Description

Technical field [0001] The benzene invention relates to an alcohol-water-soluble copolymer resin, specifically to an alcohol-water-soluble resin used as the main raw material for preparing alcohol-water-soluble fine chemical products such as alcohol-water-soluble inks, coatings, and plastic composite adhesives, and its preparation method. technical background [0002] Resin is the main raw material for the production of fine chemical products such as inks, adhesives, and coatings.
