Embodiment 1

[0029] Add 10 parts of n-pentanol directly to a 500ml four-necked flask equipped with an electric stirrer, a condenser and a thermometer, and heat up to 110°C with an electric heating mantle; 2 Under the conditions of protection, stirring, solvent condensation and reflux, the oil phase (the oil phase is 10 parts of styrene St, 5 parts of methyl methacrylate MMA, 5 parts of butyl acrylate BA, 3 parts of acrylic acid AA, methoxymethacrylate 0.1 part of methyl ethyl ester, 0.01 part of 1,4-butylene glycol dimethacrylate, 0.4 part of benzoyl peroxide) were added dropwise into the four-necked flask within 80 minutes; 0.15 parts of formyl, heat preservation reaction for 1 hour, then cool down to 60°C, add 2 parts of methylamine and 50 parts of ethanol. A functionalized acrylate emulsion with a solid content of 43% and an adhesion level of 3 can be obtained.

Embodiment 2

[0031] Add 20 parts of n-pentanol directly to a 500ml four-necked flask equipped with an electric stirrer, a condenser tube and a thermometer, and heat up to 110°C with an electric heating mantle; 2 Under the conditions of protection, stirring, solvent condensation and reflux, the oil phase (the oil phase is 20 parts of styrene St, 15 parts of methyl methacrylate MMA, 10 parts of butyl acrylate BA, 4 parts of acrylic acid AA, methoxymethacrylate 0.2 parts of methyl ethyl ester, 0.02 parts of 1,4-butanediol dimethacrylate, and 0.5 parts of benzoyl peroxide) were added dropwise into the four-necked flask within 100 minutes; 0.18 parts of formyl, heat preservation reaction for 1.2 hours, then cool down to 55°C, add 3 parts of methylamine and 40 parts of ethanol. A functionalized acrylate emulsion with a solid content of 43% and an adhesion level of 5 can be obtained.

Embodiment 3

[0033] Add 30 parts of n-pentanol directly to a 500ml four-necked flask equipped with an electric stirrer, a condenser and a thermometer, and heat up to 110°C with an electric heating mantle; 2Under the conditions of protection, stirring, solvent condensation and reflux, the oil phase (the oil phase is 25 parts of styrene St, 20 parts of methyl methacrylate MMA, 15 parts of butyl acrylate BA, 5 parts of acrylic acid AA, methoxymethacrylate 0.5 parts of methyl ethyl ester, 0.03 parts of 1,4-butylene glycol dimethacrylate, 0.6 parts of benzoyl peroxide) were added dropwise into the four-necked flask within 2 hours; 0.25 parts of formyl, heat preservation reaction for 1.5 hours, then cool down to 50°C, add 3.5 parts of methylamine and 30 parts of ethanol. A functionalized acrylate emulsion with a solid content of 43% and an adhesion level of 4 can be obtained.

Abstract

The invention relates to a preparation method of a high-adhesive-force functionalized water-soluble acrylic resin protective adhesive. The preparation method comprises the following step: by using a high-boiling-point alcohol as a solvent, carrying out solution polymerization at 110 DEG C to prepare the functionalized water-soluble styrene-methyl methacrylate-butyl acrylate-acrylic acid high-adhesive-force copolymer acrylic resin. By using the adhesive force of the copolymer acrylic resin as the main index, an orthogonal experimentation process is designed to determine the optimal preparation technique. The n-butanol / n-pentanol composite solution system is adopted, and the functional monomers methoxyethyl methacrylate and 1,4-butanediol dimethyl acrylate are commonly added, so the polymerization reaction has high stability. After the reaction is carried out for 1-4 hours, the ethanol and amine are added to obtain the high-adhesive-force functionalized water-soluble acrylic resin protective adhesive, thereby obviously enhancing the adhesive force of the traditional acrylic resin. Meanwhile, the high-adhesive-force functionalized water-soluble acrylic resin protective adhesive has the advantages of favorable film forming property, high brightness and high water solubility.

Description

technical field [0001] The invention relates to a preparation method of a strong adhesion functionalized water-soluble acrylic resin protective glue, in particular to some functional monomers, such as methoxyethyl methacrylate and 1,4-butylene glycol dimethacrylate Functionalized modified styrene / methyl methacrylate / acrylic acid copolymer can significantly improve the adhesion of traditional acrylic resins, and at the same time have good film-forming properties, good brightness and good water solubility. Background technique [0002] Water-soluble resins have been paid attention to in many ways under the premise of increasing emphasis on environmental protection. Due to its environment-friendly characteristics, water-soluble resins are favored in the coating industry and the protective adhesive industry. Standing out from the traditional solvent-based resins that pollute the environment, they have developed rapidly in the coating industry and the protective adhesive industry...
