Abstract

The invention provides an environment-friendly anti-formaldehyde acid and alkali resistant industrial coating which comprises the following components in parts by weight: 40-60 parts of acrylic resin, 5-15 parts of a chitosan-titanium dioxide-carbon nanotube compound, 0.5-1 part of a dispersing agent, 0.5-3 parts of a film-forming agent, 0.1-0.5 part of a wetting agent, 0.1-0.5 part of a defoaming agent, 0.1-1 part of a flatting agent, 0.5-2 parts of an adhesion promoter and 0.1-0.5 part of a mildew preventive, the chitosan-titanium dioxide-carbon nano tube compound is prepared from a chitosan-titanium dioxide compound and a carbon nano tube. The coating can effectively absorb formaldehyde and convert the formaldehyde into non-toxic substances, and has excellent acid and alkali corrosion resistance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an environment-friendly, formaldehyde-resistant, acid- and alkali-resistant industrial coating. Background technique [0002] In recent years, with the improvement of people's living standards, the pursuit of environmental protection, green and healthy life concepts has become the life goal of modern people. However, interior decoration materials often produce free formaldehyde, and the formaldehyde content in newly renovated houses often exceeds the standard. When the human body is in an environment with excessive formaldehyde for a long time, it will cause serious damage to health. How to effectively reduce the formaldehyde content in indoor air has become a research hotspot. Traditional methods of purifying formaldehyde include opening windows for ventilation, plant absorption, activated carbon adsorption, etc., but these methods are inefficient or cannot effectively remove formaldehy...
