Problems solved by technology

However, diatomite itself is not viscous and cannot be directly applied to coatings. It needs to be used with appropriate adhesives or additives. However, the amount of diatomite added is generally relatively low, and the use of adhesives or additives is inevitable. Harmful gas is produced, so the application of diatomaceous earth is subject to certain restrictions

Abstract

The invention relates to the technical field of building interior wall decorative materials, in particular to a preparation method of emulsion diatomiteite interior wall latex paint, which comprises the following steps: firstly, treating the surfaces of diatomiteite particles, loading metal oxide in micropores of diatomiteite, and preparing modified diatomiteite powder; by taking the obtained modified diatomiteite powder as a base material, adding a pigment filler and a preservative, heating and stirring the mixture uniformly, adding a first auxiliary agent and water, adjusting the pH value, transferring the mixture into a reaction kettle, stirring and dispersing the mixture for a certain time, and uniformly mixing the mixture to form slurry, so as to prepare a modified diatomiteite emulsion; and transferring the obtained modified diatomite emulsion into a dispersion tank, adding a second auxiliary agent, and uniformly stirring to obtain the emulsion diatomite interior wall latex paint. The process is simple, the addition amount of the diatomiteite is greatly increased, and the specific surface area and the surface negative charge of the diatomiteite are increased, so that the moisturizing and air purifying effects of the emulsion diatomite interior wall latex paint are enhanced.

Description

technical field [0001] The invention relates to the technical field of building interior wall decoration materials, in particular to an emulsion diatom interior wall latex paint and a preparation method thereof. Background technique [0002] At present, latex paints are widely used. Among interior wall materials, latex paints have always been popular for their advantages of low coating cost, rapid film formation, simple and convenient construction, saving construction costs, excellent air permeability, and washability. popular welcome. However, latex paint will inevitably release toxic and harmful gases such as formaldehyde, benzene, and TVOC during the application process, which will cause harm to the human body, and this has become a problem of increasing concern. [0003] Diatomaceous earth is the deposit of ancient single-celled diatom remains. It has abundant reserves and has a series of excellent properties such as light weight, porous, high strength, wear resistance,...
