Abstract

The invention provides an unsaturated fatty acid modified water-based acrylic resin dispersion body and a preparation method thereof. The unsaturated fatty acid modified water-based acrylic resin dispersion body comprises the following raw materials in parts by weight: 2-8 parts of unsaturated fatty acid, 2-8 parts of an acrylic epoxy monomer, 3-8 parts of an acrylic carboxyl monomer, 45-75 parts of a soft monomer and a hard monomer, 20-50 parts of a solvent, 0.3-3 parts of an initiator, 0.1-0.3 part of a catalyst, 0.05-0.15 part of a polymerization inhibitor, 0.1-0.2 part of a chain transfer agent, 2.5-5.5 parts of a neutralizer and 70-150 parts of deionized water. The preparation process is simple, the cost of the required raw materials is relatively low, and the prepared water-based acrylic resin dispersion body is relatively low in viscosity and uniform in particle size distribution which is smaller than 150 nm, can be applied to industrial anticorrosive coatings and has relatively good market application value.

Description

technical field [0001] The invention relates to the field of water-based coatings, in particular to an unsaturated fatty acid modified water-based acrylic resin dispersion and a preparation method. Background technique [0002] As an important engineering material, coatings are widely used in light industry, chemical industry, machinery manufacturing, construction and other fields. With the requirements of national environmental governance work, the production and use of a series of traditional solvent-based coatings are restricted, which has largely accelerated the development of environmentally friendly products such as water-based coatings, especially environmentally-friendly coatings represented by water-based acrylic coatings Usher in great development. The water-based acrylic resin dispersion uses water as the dispersion medium, which reduces the pollution of organic solvents to the environment during production and use, and also effectively protects the health of con...
