Embodiment Construction

[0008] An environmentally friendly epoxy resin emulsifier, consisting of the following raw materials in parts by weight: 180-230 parts of propylene glycol butyl ether, 80-120 parts of n-butanol, 100-150 parts of acrylic acid, 25-40 parts of methyl acrylate, butyl acrylate 50-70 parts, 50-65 parts of phenylacetic acid, 10-20 parts of vinyl acetate, 0.3-1.2 parts of n-dodecanethiol, 2-5 parts of dibenzoyl peroxide, preferably, 200 parts of propylene glycol butyl ether, 100 parts of n-butanol, 120 parts of acrylic acid, 30 parts of methyl acrylate, 60 parts of butyl acrylate, 60 parts of phenylacetic acid, 15 parts of vinyl acetate, 0.5 parts of n-dodecanethiol, and 3 parts of dibenzoyl peroxide.

[0009] The environment-friendly epoxy resin emulsifier improves the activity of the carboxylic acid group, and can react with the epoxy group in the epoxy resin and the curing agent at high temperature, thereby effectively improving the use efficiency of the emulsifier.

Abstract

The invention relates to the technical field of surfactants, especially to an environmentally-friendly epoxy resin emulsifier, which comprises the following ingredients (by weight): 180-230 parts of propanediol butyl ether, 80-120 parts of n-butanol, 100-150 parts of acrylic acid, 25-40 parts of methyl acrylate, 50-70 parts of butyl acrylate, 50-65 parts of phenylacetic acid, 10-20 parts of vinylacetate, 0.3-1.2 parts of N-dodecyl mercaptan, and 2-5 parts of dibenzoyl peroxide. Activity of the carboxylic group is enhanced, and the carboxylic group can react with the epoxy group in epoxy resinat high temperature and also can react with a curing agent. Thereby, the use efficiency of the emulsifier is effectively improved.

Description

technical field [0001] The invention relates to the technical field of surfactants, in particular to an environment-friendly epoxy resin emulsifier. Background technique [0002] Emulsifier is a substance that can improve the surface tension between the various constituent phases in the emulsion to form a uniform and stable dispersion system or emulsion. Emulsifier is a surface active substance with both hydrophilic and lipophilic groups in the molecule. The base, which gathers on the oil / water interface, can reduce the interfacial tension and reduce the energy required to form the emulsion, thereby increasing the energy of the emulsion. [0003] Existing epoxy resin emulsifiers introduce epoxy groups into acrylic resins, which improves the compatibility between acrylic resins and epoxy resins, but the carboxylic acid groups have poor activity and cannot meet the growing demand for use. Contents of the invention [0004] In order to overcome the existing above-mentioned d...
