Abstract
Calcium sulfate powder for coatings, the invention belongs to a kind of Chemicals, it is by calcium sulphate hemihydrate, and carboxymethyl cellulose, dextrin, talcum powder, lime carbonate and pigment mix to be formed, be solid powdery, it is simple and easy to have packing, and storing is convenient, low cost and other advantages, and is easy to use, the water distribution blending can be brushed, and can be widely used in construction wall and decorate.
Description
The invention belongs to a kind of Chemicals.
At present, liquid coating is various in style, but the Packing Fee height is all arranged, the shortcoming of storing inconvenience, solid state powder coating, through consult, have U.S. chemical abstract ///102:11449d(1984 August 23 is open) and U.S. chemical abstract, 88:8650Z(1977 July 29 is open) this powder-type coating by polyvinyl alcohol, cement, and auxiliary material forms, because of use polyvinyl alcohol, cost height, used cement, preservation period is short.
The purpose of this invention is to provide a kind of powder coating based on calcium sulphate hemihydrate.
Calcium sulfate powder for coatings of the present invention is achieved in that uses calcium sulphate hemihydrate 60-70%, carboxymethyl cellulose 4-8%, dextrin 2-4%, talcum powder 10-20%.More than the lime carbonate 10-15%(all by weight) pigment is suitable, and above material by dry, is pulverized, stir, vibration is painted can become product.
The specific embodiment prescription is
Calcium sulphate hemihydrate 70% carboxymethyl cellulose 5%, dextrin 2%, talcum powder 13%, lime carbonate 10%.
Calcium sulfate powder for coatings of the present invention, raw material is easy to get, and does not need synthetic resin (for example, the polyvinyl alcohol) technology of high price simple, and finished product is Powdered, packs simple and easyly, and storing is convenient, and the water distribution blending gets final product during use, and is with low cost.
