Abstract

The invention discloses an ecological and environment-friendly coating and a preparation method thereof. The coating is prepared from raw materials in parts by weight as follows: 0.05-0.15 parts of a pH regulator, 0.3-0.8 parts of a dispersant, 10-15 parts of a hydroxyethyl cellulose solution, 0.1-0.4 parts of a wetting agent, 0.1-0.4 parts of an antifoaming agent, 1-10 parts of negative oxygen ion powder, 10-20 parts of titanium dioxide, 0.05-0.2 parts of a molecular sieve silver-loaded antibacterial agent, 0.1-0.4 parts of a preservative, 2-10 parts of quartz / nano-titanium dioxide compound slurry, 10-20 parts of superfine quartz powder slurry, 15-40 parts of a water-based acrylic emulsion, 0.2-1.0 part of a thickening agent and 20-30 parts of deionized water. The coating has good performance, the formaldehyde purification rate is higher than 95%, the formaldehyde purification durability is longer than 90%, the antibacterial effect is higher than 90%, and the negative oxygen ion release amount is larger than 8000 per cubic centimeter.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to an eco-friendly paint and a preparation method thereof. Background technique [0002] Indoor air pollution caused by decoration materials, furniture, and daily chemicals is becoming more and more serious, causing environmental problems such as excessive formaldehyde, microbial growth, and greatly reduced indoor negative oxygen ion content. In China, as many as 111,000 people die from indoor environmental pollution every year, and the average number of deaths per day is as high as 304. Therefore, indoor air purification has become a problem that must be solved at present, and it is extremely urgent to research and develop environmentally friendly building materials for indoor air purification. [0003] Air-purifying paint is an environmentally friendly building material that can purify the air. In order to encourage the development and application of indoor air-purifyin...
