Abstract

The invention discloses water-based environment-friendly coating and a preparation method thereof. The water-based environment-friendly coating comprises the following components in percent by weight:25-33% of water, 15-28% of an environment-friendly odor-less emulsion, 1.0-2.0% of a freeze-thaw stabilizer, 0.5-1.0% of a dispersing agent, 0.15-0.3% of a wetting agent, 0.5-0.7% of a defoaming agent, 0.15-0.35% of a PH regulator, 14-23% of titanium dioxide, 10-12% of kaolin, 0-2.0% of diatomite, 5.0-20% of calcium carbonate, 0.8-1.5% of a thickening agent and 0.1-0.5% of a sterilizing agent. The water-based environment-friendly coating has good stability and dispersion and excellent scrubbing resistance; the water-based environment-friendly coating has low VOC, formaldehyde and heavy metalcontents which are close to zero, and is free of APEO. By the preparation method of the water-based environment-friendly coating, a technological condition is controllable, and the prepared water-based environment-friendly coating has good dispersion and stability and stable film forming performance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an environmentally friendly coating and a preparation method thereof. Background technique [0002] Volatile organic compounds (VOCs) and formaldehyde in indoor air mainly come from construction and decoration materials, such as: paints, adhesives, floor coverings, wall coverings and furniture, etc. These VOCs are sustained release and slow degradation process, when the VOC in people’s living room reaches a certain concentration, it will cause dizziness and nausea in a short period of time, causing blood problems in the human body, and affecting the endocrine system of the human body in the long term; formaldehyde is a carcinogen that can cause nasopharyngeal cancer in humans , nasal cavity cancer and sinus cancer, and there is evidence that formaldehyde can cause leukemia; there are five types of heavy metals that are most harmful to the environment and human body: lead, mercury, chromiu...
