Preparation method for odor-less all-effect latex paint

Abstract

The invention discloses a preparation method for odor-less all-effect latex paint. Bamboo vinegar is utilized to permeate into hollow nanocarbon microspheres under agitation, a wrapping structure is formed. The effect of the bamboo vinegar can be exerted for a long time by slow release, so that a long-term antibacterial effect can be achieved. Deionized water and water glass are utilized to treatdiatomite with heat at an appropriate temperature, the activity and catalytic property of the diatomite are improved, a hydrolyzation and stepped precipitation method is then adopted to form dispersedstable TiO2 nanoparticles with good photocatalytic activity on the surface of the diatomite, and thereby the catalytic degradation performance on methanol is good. By utilizing a silane coupling agent KH560 to exert a middle bridge effect, the prepared silica solution-organosilicone acrylate composite latex has the advantages of good film-forming property, high adhesion, no cracks and the like. The odor-less latex paint provided by the invention has good properties in removing formaldehyde, resisting bacteria and removing organic solvent, does not have pungent odor, and is environmentally friendly and nontoxic, the preparation method is simple, the cost is low, and therefore the preparation method is worth popularizing.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a preparation method of a clean-odor full-effect latex paint. Background technique [0002] Latex paint is a water-based paint prepared from synthetic resin emulsion, pigments, fillers and various additives. Due to its environmental protection, low VOC or zero VOC, excellent construction performance, good weather resistance, and excellent scrub resistance, it has become more and more popular. It is more and more used in the field of indoor and outdoor decoration. At present, the interior wall latex paint market in my country is dominated by low-cost high-volume ratio interior wall latex paint, and its market share is more than 60%. This type of latex paint contains less emulsion and a large content of pigments and fillers. The emulsion cannot completely cover the pigments and fillers during film formation, and the paint film is easy to powder and has poor scrub resistance. At th...

Problems solved by technology

This type of latex paint contains less emulsion and a large content of pigments and fillers. The emulsion cannot completely cover the pigments and fillers during film formation, and the paint film is easy to pulverize and has poor scrub resistance.

At the same time, since the raw materials for the production of interior wall latex paint contain various monomers, additives, and pigments, a certain amount of harmful substances will be released during the production and use of the product, such as volatile organic compounds (VOC), free formaldehyde, etc., which will affect people's health
