Abstract

The invention discloses a coating containing tea dust and tea polyphenol. The coating is composed of water, waterborne emulsion, titanium dioxide, a mildew preventive, a dispersing agent, a deforming agent, a pH regulator, a coalescing agent, a thickening agent, the tea dust and the tea polyphenol. Preferably, the coating is composed of 20-45% of water, 20-50% of waterborne emulsion, 10-25% of titanium dioxide, 1-5% of tea dust, 1-5% of tea polyphenol, 0.1-0.5% of deforming agent, 0.2-0.6% of dispersing agent, 0.1-0.4% of pH regulator, 0-3% of coalescing agent, 0-2% of thickening agent and 0-0.1% of mildew preventive. The tea dust and the tea polyphenol are added into the coating, so that the waste tea dust is reused on the one hand, and environment pollution can be prevented on the other hand; the coating prepared by the invention not only can be used for killing bacteria of the coating and bacteria generated in the preparation process, but also can be used for inhibiting and killing indoor bacteria when being applied to indoor decoration; and in addition, the coating can also be used for removing formaldehyde in wood and indoor formaldehyde so as to play a role of purifying air.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a coating added with tea powder and tea polyphenols and a preparation method thereof. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding pigments, fillers, and adding corresponding Additives, viscous liquids prepared with organic solvents or water. [0003] Coating refers to a type of liquid or solid material that can form a thin film on the surface of an object under certain conditions for protection, decoration or other special functions (insulation, rust prevention, mildew resistance, heat resistance, etc.). Because most of the early paints used vegetable oil as the main raw material, they are also called paints. The synthetic resin has replaced the vegetable oil, so it is called paint. Co...
