Composition of hydrophobic and antibacterial coating

Abstract

The invention discloses a composition of a hydrophobic and antibacterial coating. The composition is prepared from, by weight, 100-150 parts of styrene-acrylic emulsion, 50-100 parts of acrylate emulsion, 30-50 parts of silicone acrylic emulsion, 1-10 parts of nanosilicon dioxide, 1-5 parts of inorganic antibacterial agent, 2-5 parts of thickening agent, 5-8 parts of dispersing agent, 1-3 parts ofwetting agent, 0.5-2 parts of defoaming agent and 80-110 parts of filler. The hydrophobic and antibacterial coating integrates multiple functions, can effectively prevent breeding of staphylococcus aureus, escherichia coli and other pernicious bacteria, prevent breeding of aspergillus niger and other fungi and improve the air quality in a humid environment; meanwhile, the waterproof performance is excellent, after the composition is utilized, the phenomenon that water leaks from a wall face can be effectively avoided, and meanwhile, the antibacterial effect is excellent.

Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to a formulation of hydrophobic antibacterial coatings. Background technique [0002] With the development of society and the improvement of living standards, the global environment is deteriorating day by day, and people's awareness of environmental protection and health is gradually increasing, and the requirements for the comfort and safety of the living environment are getting higher and higher. In people's living environment, the use of coatings is indispensable, and the performance of coatings plays a vital role in the living environment. Therefore, people's requirements for coatings are getting higher and higher, especially for functions with multiple properties. In the field of architectural coatings, environmental protection and safety issues have inevitably received more and more attention. Waterproof coatings are an important part of environmentally friendly materials, especi...

Problems solved by technology

Microbes use these nutrients to undergo biodegradation, biochemical synthesis, metabolism in the body, obtain energy, and transform them into various living substances of their own. The enzymes and organic acids produced in this process can make the organic matter in the coating and the substance after film formation Continuously damaged, with the continuous reproduction of microorganisms, the degree of damage to the coating is continuously accelerated, and its viscosity decreases, demulsification, delamination, sedimentation, corruption, odor, and loss of use value
