Abstract

The invention relates to a building interior wall decorative coating, in particular to a water-based natural biological composite antibacterial coating and a preparation method thereof. The water-based natural biological composite antibacterial coating comprises the following materials in percentage by weight: 0.8-1.2% of natural chitosan-inorganic metal ion complex, 38.0-42.0% of low-VOC (Volatile Organic Compounds) pure-taste core-shell acrylic elastic emulsion, 0.4-0.6% of dispersing agent, 20.0-23.0% of titanium dioxide, 5.0-8.0% of ground calcium carbonate, 6.0-8.0% of kaolin, 0.8-1.0% of thickener and 18.0-20.0% of water. The water-based natural biological composite antibacterial coating provided by the invention has the advantages of simple preparation process and low production cost. After a finished product is used in construction, the water-based natural biological composite antibacterial coating provided by the invention has a composite antibacterial efficacy integrated with antibacterial, bacteriostasis, mildew proof and air purification properties and can be widely applied to building interior wall coating; and it is tested that the antibacterial ratio of the water-based natural biological composite antibacterial coating provided by the invention is more than 95%.

Description

technical field [0001] The invention relates to a decorative coating for building interior walls, in particular to a water-based natural biological composite antibacterial coating and a preparation method thereof. Background technique [0002] Antibacterial agents refer to chemical substances that can keep the growth or reproduction of certain microorganisms (bacteria, fungi, yeast, algae, viruses, etc.) below the necessary level within a certain period of time. [0003] At present, there are many antibacterial agents used in water-based architectural coatings, most of which are inorganic antibacterial agents and organic antibacterial agents, but they do not meet the requirements of green environmental protection from an environmental point of view. Among them, inorganic antibacterial agents use the antibacterial ability of metals such as silver, copper, and zinc. , through physical adsorption ion exchange and other methods, silver, copper, zinc and other metals (or their io...
