Problems solved by technology

Because titanium dioxide only absorbs ultraviolet light, it has a low response to visible light, and due to the recombination of photogenerated electrons and holes, the photon quantum efficiency is very low, which seriously restricts its large-scale promotion and use.

Abstract

The invention discloses an odorless anti-formaldehyde environment-friendly internal wall latex paint and a preparation method thereof. The odorless anti-formaldehyde environment-friendly internal wall latex paint is prepared from the following components in percentage by weight: 1-15% of visible light induced nano titanium dioxide photocatalyst slurry, 15-35% of odorless emulsion, 1-15% of formaldehyde absorbent, 0.5-2% of dispersing agent, 0.2-3% of thickening agent, 0.2-1% of wetting agent, 0.1-1% of defoaming agent, 0.5-5% of film-forming assistant, 0.2-3% of anti-freeze agent, 20-40% of pigment and filler, 0.1-1% of pH regulator, 0.01-0.1% of anticorrosive bactericide and 15-40% of deionized water. The invention adopts an IPS+odorless technique, and the visible light induced nano titanium dioxide photocatalyst and the formaldehyde absorbent are added, thereby achieving the optimal effect of removing formaldehyde and other harmful substances through physical adsorption and chemical decomposition. The invention can be widely used for decorative spraying of various internal walls and other constructions.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a clean-odour, formaldehyde-resistant and environment-friendly interior wall latex paint and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, a variety of building decoration materials have entered homes and offices, and VOC (volatile organic compounds) has become an important substance that pollutes the indoor air environment. Among VOCs, formaldehyde is the most common pollutant. It is mainly released through the degradation of wood adhesives and plastics used in interior decoration, decorative materials, and furniture. It poses a huge threat to human health and has become the number one killer of human health. How to remove formaldehyde and other volatile organic compounds in indoor air has become the focus of attention. [0003] Interior wall latex paint is widely used ...
