Problems solved by technology

At present, most of the diatom interior wall decoration materials sold on the market are in the form of powder or mud. The research and development of diatom mud interior wall latex paint is still in the preliminary stage. After the viscosity of the diatom mud interior wall latex paint is difficult to guarantee the environmental performance, how to balance the function of diatom mud and other materials in the latex paint, how to solve the water resistance and air permeability of the diatom mud interior wall latex paint compatible Technical problems are the technical difficulties we face

Abstract

The invention discloses an environmental-friendly diatom ooze inner wall latex paint which is prepared from the following components by weight percent: 12-18% of benzene acrylic emulsion, 10-15% of kieselguhr, 3-6% of titanium dioxide, 0.1-0.5% of a dispersing agent, 0.1-0.5% of a wetting agent, 0.5-1% of a thickening agent, 25-38% of packing, 0.2-0.4% of a defoaming agent, 1-1.5% of ethanol, 0.5-1% of a surfactant, 0.3-0.6% of an anti-molding agent and 25-40% of water, wherein the total percentage of the component is 100%. The invention further discloses a preparation method of the latex paint. Due to the addition of the kieselguhr and controlling the addition amounts of additives of the latex paint, the scrubbing resistance and the air permeability of the latex paint can be in optimal balance, the source of VOC (Volatile Organic Compounds) in the latex paint is reduced, and a prepared coating is safe and environmentally friendly, stable in property, soft and uniform in coating quality and good in adhesive property with a base material.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a diatom mud environment-friendly interior wall latex paint and a preparation method thereof. Background technique [0002] Interior wall latex paint is a kind of coating with polymer emulsion as film former, and it is a kind of water-based coating formulated with synthetic resin emulsion as base material by adding pigments, fillers and various additives. Interior wall latex paint is one of the main decorative materials for interior walls and ceilings. It is characterized by good decorative effects, convenient construction, little environmental pollution, low cost, and extremely wide application. [0003] With the development of the economy, people's material and cultural living standards are improving day by day, environmental protection and health awareness are generally enhanced, and the requirements for the safety and comfort of the living environment are getting higher and ...
