Abstract

The invention discloses environment-friendly latex paint for wall bodies and a preparation method thereof and relates to the technical field of wall body paint. The environment-friendly latex paint isprepared from the following raw materials in parts by weight: 35 to 42 parts of main material, 3 to 10 parts of thalatherm, 6 to 15 parts of wollastonite powder, 8 to 16 parts of calcium carbonate, 5to 10 parts of mica, 3 to 8 parts of attapulgite, 4 to 6 parts of titanium dioxide, 4 to 8 parts of bamboo fiber, 3 to 8 parts of ceramic fiber, 1 to 3 parts of nano silicon dioxide, 1 to 3 parts ofnano titanium dioxide, 1 to 3 parts of nano zinc oxide, 4 to 7 parts of silane coupling agent, 5 to 8 parts of dispersal latex powder, 1 to 2 parts of dispersant, 2 to 4 parts of anti-bacterial and antiseptic agent and 2 to 4 parts of film form aid. The raw materials of the environment-friendly latex paint for the wall bodies disclosed by the invention are chemical substances which have no toxin and are not prone to volatilizing, and the latex paint has the advantages of no formaldehyde matter, stable chemical property, no harm to human body health, good adhesion, easiness in being painted evenly, simple and easy preparation technology, low raw material cost and suitability for large-scale popularization and production.

Description

technical field [0001] The invention relates to the technical field of wall coatings, in particular to an environmentally friendly latex paint for walls and a preparation method thereof. Background technique [0002] At present, there are many types of coatings used in daily decoration, and latex paint is one of the most widely used wall decoration materials. In recent years, with the development of the economy, people's awareness of environmental protection and health has been continuously improved, and the selection of wall decoration materials used in architectural decoration has become more and more strict. Toxic substances in air pollution are the main factors that cause people's physical damage. It is medically proven that when the indoor formaldehyde content exceeds a certain amount, it will cause people to have headaches, nausea, vomiting, fatigue and other discomfort symptoms. Convulsions, coma, memory loss, damage to the liver, kidneys, brain and nervous system. ...
