Nanometer material mould-proof formaldehyde-removing environment-friendly coating and preparation method thereof

Abstract

The invention discloses a nanometer material mould-proof formaldehyde-removing environment-friendly coating. The coating is prepared from the following raw materials in parts by weight: 4 to 6 parts of formaldehyde absorbing agent, 10 to 16 parts of formaldehyde-removing filler, 8 to 14 parts of effective adjuvant, 9 to 15 parts of nanometer material, 2 to 4 parts of silane coupling agent, 28 to 36 parts of high-molecular polymer, 0.2 to 0.8 part of petal extracting solution, 2 to 4 parts of lubrication-increasing water mist-proof wax powder and 7 to 9 parts of organic solvent. The coating disclosed by the invention has an excellent formaldehyde-removing and air-purifying performance, is relatively good in a mould-proof and sterilizing performance, and poisonless and harmless, has the fragrance of flower, and is relatively excellent in a caking property and surface flatness; meanwhile, raw material components of the coating are safe and reliable, healthy and harmless to human bodies, the raw materials are available, the cost is relatively low, and the process is simple. Therefore, the coating has relatively high practical value and a good application prospect.

Description

technical field [0001] The invention relates to the technical field of nanomaterials, in particular to a nanomaterial anti-mildew and formaldehyde-removing environmental protection coating and a preparation method thereof. Background technique [0002] On the one hand, having fresh air can eliminate the fatigue of the day, relax the tense body and mind, and benefit the physical and mental health of the human body. Indoor air quality is very important to human health. People are paying more and more attention to the problem of microbial pollution in indoor air.

[0002] On the one hand, having fresh air can eliminate the fatigue of the day, relax the tense body and mind, and benefit the physical and mental health of the human body. Indoor air quality is very important to human health. People are paying more and more attention to the problem of microbial pollution in indoor air. In addition, , Many public places cannot naturally purify the environment through fresh air due to reasons such as poor ventilation, and it is inevitable that odors will accumulate, making people feel uncomfortable

[0003] On the other hand, with the rapid development of the paint industry, various environmentally friendly coatings emerge in endlessly, and their prices are mostly expensive. The existing environmentally friendly coatings, especially the environmentally friendly coatings on the wall, are usually prone to the following problems during use: The surface is prone to mildew or oxidation, causing the paint to fall off, especially in the southern rainy season, when the air is humid, it is more likely to have mildew on the wall, and the water resistance is poor, which brings a lot of inconvenience to consumers; the existing large Some paint products contain certain harmful substances such as formaldehyde and volatile organic compounds, which usually emit an unpleasant smell for a long time and have poor environmental protection performance

Although the products of the existing paint manufacturers can meet the limit standards for harmful substances stipulated in the national standards, they have not clearly stated that they do not contain certain harmful substances. The harmful substances in the existing paints not only cause harm to the human body, but also polluted environment

Existing environmentally friendly coatings, whether water-based or solvent-based, are mixed with anti-mildew agents in liquid paints. However, most of these agents mixed into paints are pesticides, and sometimes they are also used Organic mercury-based or arsenic-based compounds, so the paint is more or less toxic. Although the effect is good, the ubiquitous safety problems need to be solved
