Abstract

An environment protection type emulsoid paint without VOC is prepared from water, sodium polyacrylate "5040", hydroxyethyl cellulose "250HBR", mineral oil modified silicone BYK-003, titanium white powder, filming agent and assistant. Its advantages are high hardness and adhesion, high resistance to dirt, zero VOC and no poison and harm.

Description

technical field [0001] The invention relates to a latex paint, in particular to a water-based latex paint with high-quality ring retention, which is suitable for interior and exterior wall decoration and can be coated on surfaces such as cement, mortar, plaster, cement asbestos board, and trihexite. Background technique [0002] At present, the international and domestic environmental protection calls are getting louder and louder, and the restrictions on VOCs for interior and exterior wall paints are becoming more and more strict. However, the VOCs of most domestic latex paints are above 60, and even more, around 200. The amount of latex paint is increasing every year, so although it is water-based, the environmental pollution cannot be underestimated, and it has a greater impact on human health. Therefore, people use various methods to solve the environmental protection problem of latex paint. However, to solve the environmental protection problem of latex paint, we can on...
