Abstract

The invention provides an environment-friendly waterborne acrylic coating and a preparation method thereof. The preparation method comprises the following steps of: mixing raw materials to obtain a mixture I, and then mixing the mixture I with waterborne acrylic resin and an additive in sequence to finally obtain the environment-friendly waterborne acrylic coating. The environment-friendly waterborne acrylic coating prepared by the invention has excellent comprehensive performance and relatively high efficiency of photocatalytic degradation of formaldehyde, so that the environment-friendly waterborne acrylic coating prepared by the invention can be applied to the field of environmental protection.

Description

Technical field [0001] The invention relates to the field of water-based paints, in particular to a preparation method of environmentally-friendly water-based acrylic paints. Background technique [0002] Since the 1980s, due to the successive production and application of acrylic monomers, the industrial development speed of polyacrylate coatings has greatly increased. With the rapid development of science and technology, people have a deeper understanding and understanding of acrylic resins, and promote The development and application of it in the coating industry. So far, acrylic resin has developed into a type of paint with the most types and the most comprehensive performance. It has both superior decorative performance and good protection performance. Especially the solvent-based acrylic resin with a long history plays a pivotal role. . [0003] The prepared water-based acrylic paint has the advantages of simple synthesis and processing, low price, safety and environmental ...
