Problems solved by technology

[0007] Although vinyl acetate is cheap and has low toxicity as the main raw material for preparing alcohol-soluble materials, the polymer itself has a low softening point and is easily deformed by heat. Most of its autopolymerization or copolymerization structures are linear, and functional monomers are generally used to form To change the properties of the copolymer, in terms of balancing related properties such as: low viscosity / high solid content, pigment dispersion / adhesion, etc., the method appears to be single, low in efficiency, and narrow in scope
At present, there are no reports at home and abroad that use vinyl acetate as the main raw material and change the performance of vinyl acetate alcohol-soluble resin by introducing a certain structure.

Abstract

The invention relates to an alcohol soluble material with a flagellum structure and a preparation method thereof and application, in particular to a high-performance alcohol soluble material which is obtained by taking unsaturated polyester oligomer as a flagellum structure introduction body, taking vinyl acetate as a main monomer, taking acrylic ester or methacrylic ester monomers as auxiliary monomers and adjusting the composition, molecular weight and addition amount of the unsaturated polyester flagellum structure oligomer in a mode of free radical polymerization. The material has the advantages of being clear in structure, adjustable in viscosity, controllable in synthesis and good in reproducibility. Environment-friendly ethyl alcohol and the like are adopted as solvents, and the alcohol soluble material has the advantages of being excellent in adhesive force, low in viscosity and good in pigment dispersibility and can be applied to adhesive, ink and coating and the like and have very good market application values.

Description

technical field [0001] The invention relates to the technical field of fine chemical materials and applications, mainly an alcohol-soluble material with a flagellar structure and its preparation method and application, specifically relates to an alcohol-soluble material and its preparation method, the material can be used as The main resin when preparing alcohol-soluble fine chemical products such as alcohol-soluble ink and alcohol-soluble plastic composite adhesive. Background technique [0002] At present, most of the organic solvents used in solvent-based inks, adhesives, coatings and other fine chemical products are harmful and toxic benzene or ketone solvents, which seriously pollute the environment. Although many products are now developing in the direction of water-based, there are insurmountable technical problems in terms of water-based drying speed and applicability, which greatly limit the application fields of water-based products. Alcohol-soluble resin, as a tr...
