Abstract

The invention discloses dry powder type oyster shell powder ecological paint capable of efficiently decomposing formaldehyde and a preparation method thereof and belongs to the field of dry powder paint. The dry powder type oyster shell powder ecological paint comprises the following components in parts by weight: 30-50 parts of oyster shell powder, 10-20 parts of diatomite, 15-25 parts of volcanic ash, 5-15 parts of dispersible pure plant gelatin powder, 4-5 parts of tourmaline-loaded nano titanium dioxide, 0.1-1 part of adipic acid dihydrazide, 0.3-0.8 part of cellulose ether and 0.4-0.5 part of a de-foaming agent. Through reasonable gradation, the dry powder type ecological paint capable of efficiently decomposing the formaldehyde can be obtained; when in use, the dry powder type oyster shell powder ecological paint is added with water and then is stirred to be used as a replacement of emulsion paint, so that the problem of high storage and transportation cost of traditional emulsion paint is effectively solved.

Description

technical field [0001] The invention relates to the field of dry powder coatings, in particular to a dry powder type oyster shell powder ecological paint capable of efficiently decomposing formaldehyde and a preparation method thereof. Background technique [0002] In the coatings industry, it is the general trend to replace the heavily polluting solvent-based coatings with water-based coatings and powder coatings, and water-based coatings have also been widely used. However, the architectural water-based latex coatings currently used are composed of polymer emulsions, fillers, additives and water, among which additives and water are used for the production and storage of coatings, accounting for more than half of the weight and price of coatings. Most of the water-based paint is water. The storage and use of liquid latex paint requires a large number of plastic or iron storage tanks. The recycling of the storage tank requires a lot of manpower and material resources, which ...
