Problems solved by technology

It is used to replace wallpaper and latex paint, and is suitable for interior wall decoration of villas, apartments, hotels, homes, hospitals, etc. However, the materials used in diatom mud produced by many manufacturers are extremely unreasonable, and the surface area of ​​diatom earth is sealed. The performance of diatom mud is greatly reduced, and a more reasonable formula system is needed to develop diatom mud coatings, so as to provide people with better decorative materials

Abstract

The invention relates to a two-component diatom mud water-based paint free of emission of VOCs. The two-component diatom mud water-based paint is characterized by being composed of a component A and acomponent B. The component A is prepared from the following raw materials in parts by weight: 0.5-1 part of potassium persulfate, 30-40 parts of diatom mud powder, 10-15 parts of rutile titanium dioxide powder, 6-12 parts of far-infrared ceramic powder, 45-75 parts of water, 1-2 parts of a leveling agent and 0.3-0.6 part of a defoaming agent. The component B is prepared from the following raw materials in parts by weight: 6-12 parts of a crosslinkable monomer, 2-4 parts of an antibacterial monomer, 0.1-0.3 part of a catalyst, 3-5 parts of water-based stearate and 15-25 parts of water. The two-component diatom mud water-based paint has good effects of resisting bacteria and purifying air, and has broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, and relates to a two-component diatom mud water-based coating with zero VOC emission. Background technique [0002] With the rapid development of the national economy and the gradual improvement of people's material living standards, interior decoration has become increasingly popular. People spend two-thirds of their life indoors, and modern people spend 80%-90% of their time indoors living and working in an indoor environment. Therefore, the quality of the indoor environment directly affects people's health. [0003] Diatom mud is a kind of dry powder interior wall decoration coating material prepared with inorganic gelling substance as the main bonding material and diatom material as the main functional filler. It has the functions of eliminating formaldehyde, purifying air, adjusting humidity, releasing negative oxygen ions, fire retardant, wall self-cleaning, sterilization an...
