Abstract

The invention discloses a water-based environment-friendly coating material and a preparation method thereof and belongs to the technical field of coating material preparation. The water-based environment-friendly coating material is prepared from the following raw materials: water-soluble acrylic resin, nano-scale kaolinite, nano-scale montmorillonite, a PBMA-b-PDMAEMA dispersant, diatomite, an acetylene diol antifoamer, tri(hydroxymethyl)propane-tri(3-aziridinyl)propionate, a sodium alginate thickener, a polydimethylsiloxane, a twin siloxane humectant, carboxymethyl chitosan silver, titaniumdioxide and deionized water. The water-based environment-friendly coating material is prepared through the steps of water-soluble acrylic resin preparing, ingredient dispersing, mixing preparation and the like. The water-based environment-friendly coating material disclosed by the invention is good in ingredient compatibility and high in weather resistance and has certain antibacterial capability, and the surface of the coating material can be prevented from generating bacteria and molds; organic pollutants of surrounding environments can be effectively absorbed, so that the water-based environment-friendly coating material is novel.

Description

【Technical field】 [0001] The invention belongs to the technical field of paint preparation, and in particular relates to a water-based environmental protection paint and a preparation method thereof. 【Background technique】 [0002] Water-based coatings have developed rapidly in recent years due to their environmental protection, safety, and coating and construction characteristics. However, water-based coatings also have the disadvantages of poor durability and easy mildew. At the same time, most water-based paints still contain a large amount of organic components, so that some organic substances will still be released after coating, which is not conducive to human health. [0003] Chinese invention patent application document "A water-based environmental protection coating (application number: 201510779538.1)" discloses an environmental protection water-based coating and its preparation method, which is composed of the following raw materials in parts by weight: water-sol...
