Nanometre photocatalysed formaldehyde-eliminating emulsion paint and preparation method thereof

Abstract

The invention discloses a nanometre photocatalysed formaldehyde-eliminating emulsion paint and a preparation method thereof. The nanometre photocatalysed formaldehyde-eliminating emulsion paint comprises the following components in percentage by weight: 20-30% of water, 0.5-1.0% of dispersing agent, 0.2-0.4% of defoaming agent, 0.1-0.5% of wetting agent, 0.1-0.8% of cellulose, 0.05-0.27% of pH regulating agent, 6-18% of nanometre photocatalysis inorganic material, 25-40% of pigments and fillers, 0.2-1.0% of inorganic antibacterial auxiliary, 25-40% of formaldehyde-eliminating acrylic emulsion, 1-3% of film-forming auxiliary, 0.3-0.8% of levelling agent, and 0.5-2% of thickening agent. The formaldehyde-eliminating emulsion paint is capable of absorbing free formaldehyde existing in an environment for a long time. The invention further discloses a method for preparing the formaldehyde-eliminating emulsion paint, and the method is capable of improving the formaldehyde-eliminating effect of the emulsion paint.

Description

technical field [0001] The invention relates to the field of fine chemical coatings, in particular to a latex paint capable of effectively absorbing free formaldehyde present in the environment, and a preparation method of the latex paint. Background technique [0002] With the continuous development of the economy, people's awareness of environmental protection has been promoted, and the quality of environmental protection has been widely concerned by people. While the use of a large number of decoration materials improves the quality of life, it also causes the continuous deterioration of indoor air quality; the existing formaldehyde removal For latex products, the main technology is to add diatom mud, bamboo charcoal and other substances. These substances are porous structures. In principle, they are only adsorption, not real reactive decomposition. The effect of adding such substances on formaldehyde removal is not good and will not last long. . [0003] Although the fo...

Problems solved by technology

[0003] Although the formulation of "aldehyde-cleaning" latex paint has a history of many years at home and abroad, due to immature technology, it is impossible to apply "nano-inorganic materials" aldehyde-removing acrylic emulsion and inorganic antibacterial agent to the formula of latex paint at the same time In order to improve the long-lasting aldehyde removal effect of latex paint
