Problems solved by technology

[0003] In recent years, although water-based and alcohol-soluble polyurethane plastic gravure inks and other types of alcohol-soluble inks have appeared in the market, there are problems such as high price, poor wetting and dispersibility of pigments, and slow drying, which affect the popularization and use of such products. As far as acrylic related resins and inks are concerned, only a few kinds of products are used in China, and there is no supply of such resins for full-chromatographic alcohol-soluble plastic gravure inks.

Abstract

An alcohol-soluble acrylic thermoplastic resin and a preparation method thereof. The resin comprises raw materials in the following weight ratio: 8-30 parts of methacrylate, 25-50 parts of acrylate, 10-20 parts of active functional group monomer, tertiary carbonic acid 2-5 parts of glycidyl ester, 2-5 parts of cationic functional monomer, 0.5-0.7 part of initiator, 10-15 parts of rosin addition polymer, and 0.2-0.5 part of catalyst. It has the characteristics of low pollution, low cost, good wetting and dispersibility of pigments, fast drying, and good printing suitability.

Description

technical field [0001] The invention relates to a synthetic resin and a preparation method thereof, in particular to a packaging resin material and a preparation method thereof. Background technique [0002] Alcohol-soluble acrylic thermoplastic resin is the main material used in printing inks for plastic packaging, and is also used in adhesives for composite packaging, and can be used for adhesives in paint production. The performance of its resin determines the solvent type of ink and coating, and determines the printing suitability of ink, pigment dispersibility, adhesion fastness, ink toxicity and environmental protection performance. For a long time, my country's plastic gravure ink is synthesized with benzene-soluble Resin is the main body, and the ink contains a large amount of benzene solvents. Therefore, there is volatilization pollution of benzene solvents during the manufacture and use of inks, which endangers the health of producers and consumers. What's more ser...
