Abstract
The invention discloses healthy interior wall coating with zero VOC. The healthy interior wall coating with zero VOC is processed and prepared through a plurality of working procedures such as taking deionized water, titanium dioxide, emulsion, ultra-fine calcium carbonate and ultra-fine talcum powder as the main raw materials and adding dispersing agent, flow agent, thickening agent, anti-mildew agent, film-forming agent and anti-foaming agent as the special auxiliary agent. The invention also discloses a preparation method of the zero-VOC healthy interior wall coating, because the coating adopts a clean production technology, during the process of production and construction, the coating has low-volatile organic matter content, the indexes of soluble heavy metal and the ecological toxicity are lower than the national standard, and the content of the volatile organic matter (VOC) is zero. The heavy metal compound is less than 500 mg/kg, the content of the polymer of formaldehyde and formaldehyde is less than 500 mg/kg, the coating has no environmental pollution and no harm to the human body, and the obvious effects of environmental protection and antibiosis are realized. The healthy interior wall coating with zero VOC has the advantages of good tank opening performance, leveling property of coating, strong coverage rate, washing resistant performance, fading resistance, alkali resistance, mold fungus resistance, asepsis and tasteless.
Description
technical field [0001] The invention relates to the technical field of architectural wall coatings, in particular to a zero-VOC healthy interior wall coating and a production method thereof. Background technique [0002] At present, known architectural interior wall paints are prepared from water, titanium dioxide, emulsion, fillers and various additives. Due to the lax selection of materials, the paints contain halogenated hydrocarbons, benzene series substances, heavy metal compounds, formaldehyde, etc. Toxic substances such as polymers and volatile organic compounds are difficult to volatilize in a short period of time indoors, so they bring different degrees of harm to the environment and human body. Contents of the invention [0003] One of the problems to be solved by the present invention is to provide a zero-VOC healthy interior wall paint with less harmful volatile matter and no pollution to the environment, so as to solve the problem of environmental pollution ex...
