Novel environment-friendly coating

Abstract

The invention provides a novel environment-friendly coating, and relates to the technical field of coatings. The novel environment-friendly coating, calculated in parts by weight, is prepared from thefollowing materials: 18 to 20 parts of nano silicon dioxide, 18 to 20 parts of nano titanium dioxide, 20 to 40 parts of titanium dioxide, 31 to 43 parts of an auxiliary agent, 40 to 60 parts of emulsion paint, 25 to 40 parts of deoxygenated water, 5 to 15 parts of activated carbon powder, 10 to 15 parts of color paste, 18 to 20 parts of white carbon black, 7 to 13 parts of an active agent, 3 to 4parts of nano silver and 8 to 12 parts of metal oxide. The nano silicon dioxide and the nano titanium dioxide are matched without any illumination condition; harmful substances such as formaldehyde can be actively decomposed; the activated carbon powder can actively absorb the harmful substances such as formaldehyde to enable the coating to be energy-saving, the white carbon black carrier can fixthe nano titanium dioxide, loss of nano titanium dioxide powder particles is prevented, the utilization rate of the nano titanium dioxide is increased, the white carbon black carrier is easy to recycle, and the coating is enabled to be environment-friendly.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a novel environment-friendly coating. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. "Paint is a material that can be coated on the surface of an object by different construction techniques to form a solid film with firm adhesion, certain strength and continuity. The film formed in this way is commonly called a coating film, also known as a paint film or a coating Layer." In the early days, most of the paints used vegetable oil as the main raw material, so they were called "paints". Chemical polymer materials, the formed coating film belongs to the polymer compound t...

[0003] With the development of China's economy and the acceleration of urbanization, many people have moved into new houses. New houses need to be decorated when they live in them. Paint is used during the decoration. The harmful substances in the original paint latex paint are mainly " The content of "volatile organic compounds" and "free formaldehyde", among which "volatile organic compounds" are generally referred to as VOC, excessive VOC can irritate human skin and eyes, damage nerves, hematopoietic and other systems, and seriously endanger human health. The Limits of Hazardous Substances in Decoration and Renovation Materials restricts the VOC content of latex paint, and stipulates that the VOC standard is 200 g / l. In the current coating production process, coalescents and antifreeze are the main sources of VOC in coatings. , limited by the current paint raw materials and paint production level, in order to ensure and improve the paint film performance of the paint, it is necessary to add organic solvents (the main source of VOC) to the paint. The addition of organic solvents increases the VOC content of the paint. Reduce the environmental protection of coatings, simply reduce the content of organic solvents, although the environmental protection performance is enhanced, but the coating film properties, which is one of the important properties of coatings, will be affected

Therefore, some latex paints are expensive due to their strong covering power. Many people mistakenly think that the more expensive the better, in fact, there may be more harmful substances in them. Formaldehyde is an irritating gas with a strong gas and is a volatile organic paint. Compound, formaldehyde is identified as a suspected carcinogen by the International Agency for Research on Cancer, so the content of formaldehyde should also be paid attention to. Slower, need to use a large amount of formaldehyde-removing substances to remove, resulting in the existing coatings not being energy-saving and environmentally friendly
