Ecological shell powder inorganic nanometer composite coating material and preparation method thereof

Abstract

The present invention relates to an ecological shell powder inorganic nanometer composite coating material and a preparation method thereof. The ecological shell powder inorganic nanometer composite coating material comprises, by mass, 70-90% of shell powder and 10-30% of a composite glue adhesive, wherein the shell powder contains 1-3% by mass of titanium dioxide nanoparticles and 1-3% by mass of tourmaline powder, and the composite glue adhesive contains 80-90% by mass of water, 3-10% by mass of polyvinyl alcohol, and 0.5-3% by mass of cellulose. According to the present invention, natural shell powder is adopted as a main material, any toxic and hazardous substances are not added, and the ecological shell powder inorganic nanometer composite coating material has functions of indoor toxic gas absorption and decomposition, and has the following characteristics that: construction is simple, shedding due to scrubbing can not be generated, negative oxygen ions can be released for a long time so as to carry out a purification and sterilization treatment on indoor air.

Description

technical field [0001] The invention relates to a novel environment-friendly interior wall paint and a preparation method thereof, in particular to an ecological shell powder inorganic nanocomposite paint and a preparation method thereof. Background technique [0002] The interior wall paints currently used are mainly acrylic latex paints and lime paints that use polyvinyl alcohols as binders, both of which have the disadvantages of pollution and single function. At present, the world's architectural interior wall coatings are developing in the direction of pollution-free and environmentally friendly. In the interior decoration process, a large number of decoration materials such as paint, plywood, leather, foam fillers, and plastic veneers contain hundreds of volatile and toxic substances. These toxic and harmful gases seriously endanger human health and the living environment. [0003] With the increasing awareness of environmental protection, people have higher and highe...

Patent literature (publication number: CN 1370807A) discloses a kind of water-based wall paint using shell powder, which has strong adhesion, comprehensive properties such as washing resistance and anti-aging, and simultaneously reduces toxicity and has certain safety and environmental protection properties, but The paint system does not add materials that can decompose harmful gases, so it cannot effectively purify indoor air

The patent document (publication number: CN 101774785A) discloses a kind of interior wall paint with shell powder as the main component. It uses shell calcium carbonate and calcium oxide as the main materials, uses dispersible latex powder as the binder, and adds nano-titanium dioxide and negative ion powder have a certain effect of purifying the air, but the nano-titanium dioxide and negative ion powder in the coating system are directly added to the shell powder, and the two are just a simple mixture without forming a stable and firm combination. During construction and use, the effect of the paint on purifying the air is limited and not sustainable
