Abstract

The invention discloses an environment-friendly inner wall coating material and a production process thereof. The coating material is prepared form the following raw materials in parts by weight: 100 to 120 parts of diatomite, 50 to 70 parts of bentonite clay, 15 to 30 parts of meerschaum, 20 to 30 parts of calcined kaolin, 8 to 20 parts of calcium hydroxide powder, 5 to 10 parts of bamboo carbon fibers, 1 to 5 parts of polyester fibers, 0.6 to 2 parts of sodium perborate, 1 to 3 parts of nano zinc oxide, 0.2 to 0.6 part of calcium perborate, 0.1 to 0.5 part of dispersant, 0.2 to 0.8 part of wetting agent, and 0.1 to 0.3 part of anti-foaming agent. The production process of the coating material comprises the following steps: purifying the diatomite, mixing the diatomite, and carrying out ball-milling on the diatomite. According to the environment-friendly inner wall coating material disclosed by the invention, all components are safe and environment-friendly, heat insulation and flame retardance performance are excellent, and the inner wall coating material is antibacterial and bacteriostatic, water-proof, mildew-proof and corrosion-resistant; the production process is simple, is saving in energy sources, and is suitable for massive production.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an environment-friendly interior wall coating material and a production process thereof. Background technique [0002] With the development of society and the improvement of living standards, people's awareness of environmental protection and health has been significantly enhanced, and the requirements for the comfort and safety of the living environment are getting higher and higher. Indoor temperature, air relative humidity, and air quality are important environmental parameters for living comfort. Diatom mud is an indoor coating material based on diatomaceous earth, which is a single-celled aquatic plankton that lived millions of years ago. The main component of diatomite is protein, which is light, soft and porous, with a porosity of more than 90% and a specific surface area of ​​65m2. 2 / g, which determines its strong physical adsorption performance and ion exch...
