Nano-photocatalytic composite haze and formaldehyde removal latex paint and preparation method thereof

Abstract

The invention discloses a nano-photocatalytic composite haze and formaldehyde removal latex paint. The latex paint is characterized by consisting of the following components in percentage by weight: 20-25% of water, 1.5-2% of polymeric dispersants, 2-2.5% of multifunctional auxiliaries, 25-35% of a nano-photocatalytic carbon-silicon composite raw material, 15-20% of filler and pigment, 20-30% of an emulsion and 1-2% of a coalescing agent. The latex paint disclosed by the invention can effectively absorb PM2.5 particulate pollution, free formaldehyde, benzene, methylbenzene, dimethylbenzene, ammonia gas and the like existing in the environment for a long time; the invention also discloses a method for preparing the composite air purifying latex paint; and the effect of the latex paint on effectively absorbing the PM2.5 particulate pollution, free formaldehyde, benzene, methylbenzene, dimethylbenzene, ammonia gas and the like can be improved.

Description

technical field [0001] The invention relates to the field of fine chemical coatings, in particular to an emulsion paint capable of effectively absorbing PM2.5 fine dust and free formaldehyde existing in the environment, and a preparation method of the emulsion 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. The use of a large number of decoration materials has not only improved the quality of life, but also caused the continuous deterioration of indoor air quality; the existing air purification Formaldehyde-removing latex products, the main technology is to add diatom mud, bamboo charcoal and other substances. These substances are porous structures, which are only limited adsorption in principle analysis, not real reactive adsorption and decomposition. Adding such substances has little effect on...

Problems solved by technology

[0002] With the continuous development of the economy, it promotes the improvement of people's awareness of environmental protection, and the quality of environmental protection has attracted widespread attention. The use of a large number of decoration materials has not only improved the quality of life, but also caused the continuous deterioration of indoor air quality; the existing air purification Formaldehyde-removing latex products, the main technology is to add diatom mud, bamboo charcoal and other substances. These substances are porous structures, which are only limited adsorption in principle analysis, not real reactive adsorption and decomposition. Adding such substances has little effect on formaldehyde removal. well not long lasting

[0003] Although the formulation of "air purification" latex paint has a history of many years at home and abroad, due to immature technology, it is impossible to apply "nano-inorganic materials", acrylic emulsion, and nano-zinc oxide liquid materials to latex paint at the same time. In the formulation, to enhance the effective absorption of PM2.5 fine dust in the environment and the long-lasting dealdehyde effect of latex paint
