Abstract

The invention provides an environment-friendly antimicrobial interior wall coating containing shell powder and a preparing method of the environment-friendly antimicrobial interior wall coating. The environment-friendly antimicrobial interior wall coating is prepared from, by weight, 40-60 parts of binder, 80-100 parts of shell powder, 20-30 parts of kaolin, 20-30 parts of emulgator, 5-8 parts of dispersing agent, 1-3 parts of citric acid monohydrate, 1-5 parts of water reducing agent, 1-1.5 parts of litsea cubeba oil, 0.3-1 part of clove oil, 0.2-0.4 part of cinnamon oil, 0.5-0.8 part of natamycin, 0.5-1 part of allicin, 0.2-0.5 part of propionic acid, 0.3-0.6 part of sorbic acid, 0.1-0.4 part of fumaric acid, 0.5-0.7 part of sodium diacetate, 0.1-0.3 part of mannan, 10-15 parts of porous starch, 2-5 parts of chitosan and 80-100 parts of water. The environment-friendly antimicrobial interior wall coating can adsorb formaldehyde and volatile harmful gas in air, lower the content of formaldehyde and volatile harmful gas, and prevent mildews and microorganism breeding of an interior wall in the later period.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an environment-friendly and antibacterial interior wall 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 nu...
