Abstract

The invention provides environmentally friendly paint containing shell powder and a preparation method of the paint. The paint is prepared from the following raw materials in parts by weight: 40-70 parts of a biosynthetic binder, 80-100 parts of shell powder, 20-30 parts of kaoline, 10-20 parts of porous starch, 5-10 parts of chitosan, 5-10 parts of mosquito-repellent essential oil, 5-10 parts of pyrethrin, 20-30 parts of an emulgator, 5-8 parts of a dispersing agent, 1-3 parts of citric acid monohydrate and 80-100 parts of water; the biosynthetic binder is prepared from the following ingredients: konjac glucomannan, sodium alga acid, starch acetate, carboxymethyl chitosan, polyvinyl alcohol and water. The paint provided by the invention can be used for adsorbing formaldehyde and volatile harmful gas in the air and reducing the content of the formaldehyde and the volatile harmful gas, and has a mosquito-repellent effect, thereby preventing mosquitoes from infestation in days to come.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an environment-friendly coating containing shell powder and a preparation method thereof. Background technique [0002] In the field of building materials, interior wall paint is a kind of building material product used for painting and decoration of interior walls of buildings. It is a necessary material for buildings, and its usage is also very huge. However, some traditional interior wall coating compositions may cause non-negligible emissions of harmful volatile components such as formaldehyde, benzene, ammonia, and VOC. According to the report of the World Health Organization, 68% of modern human diseases are related to indoor air pollution. Statistics from Beijing Children's Hospital show that 90% of children with leukemia are caused by formaldehyde pollution. According to the data provided by the China Indoor Environmental Monitoring Center, the number of deaths caused by indoor ...
