Problems solved by technology

[0005] However, to achieve these functions, the rise in manufacturing costs will become a major problem
[0006] In addition, regarding the application of coal ash, an industrial waste, as shown in the patent document JP-A-2000-000769, fly ash produced in a coal-fired power plant is used as a raw material, mixed with a binder, and then After curing, it is crushed into fine particles to be used as a sweeping material to remove rust or paint on iron walls, etc. This application technique is known to the public, but the application of coal ash to the paint itself has not been found

Embodiment Construction

[0019] To further illustrate the present invention, the manufacturing techniques of this process are very clear to those skilled in the art.

[0020] Generally speaking, paint components are composed of "coating film forming components" vehicle (vehicle) and "pigment components".

[0021] As a "coating film-forming component", the vehicle is equivalent to a clear coating, which can disperse pigments, etc., and at the same time improve the fluidity of the coating. As for the "pigment component", it is the component that imparts color to the coating film. According to the solvent, it can be divided into oil-based paint and water-based paint.

[0022] The coating composition of the present invention consists of:

[0023] (a) "coating film forming components": the main body adopts coal ash remaining after coal combustion (hereinafter referred to as "coal ash");

[0024] (b) "Pigment component": The pigment component has a pigment component capable of dispersing the pigment in th...

Abstract

The invention relates to a coating made of coal ashes. The coating is related to ingredients of coatings, in particular to forming ingredients of coating films. The coating comprises a coating film forming ingredient and a pigment ingredient, the pigment ingredient is mainly composed of acrylic resins, the coating is characterized in that the weight of the coal ashes is 40-60% of the coating film forming ingredient, the pigment ingredient is mixed into the coating film forming ingredient and is capable of dispersing pigments when an acrylic resin emulsion or a vinyl acetate emulsion is subjected to emulsification treatment, and the coating film forming ingredient comprises 5-7% of hydroxyethyl cellulose, 0-15% of titanium oxide, 12-14% of water, and the balance dispersing agents and foam inhibitors. Compared with coatings in prior art, the coating has the advantages that the main raw material of the coating is the coal ashes which are low in price and easy to obtain, and fine bumps are formed on the surface of the obtained coating due to the fact that the coal ashes comprise particles of quartz aluminium oxide, silicon oxide (SiO2) and the like, so that blots are difficult to adhere to the surface of the coating, and the surface of the coating is glossy.

Description

[Technical field] [0001] The present invention is related to the composition of the coating material, especially the coating film-forming composition of the coating material, specifically a coating made of coal ash. [Background technique] [0002] As shown in Japanese Patent Laid-Open No. 56-131693, there is an increasing demand for coatings that mix coal ash powder and slurry, as well as coatings that add various functions and realize more added value. [0003] For example, after using titanium oxide for surface processing, a photocatalytic reaction will occur when light (ultraviolet rays) is irradiated, and the organic matter attached to the surface will be oxidized and decomposed into water and carbon dioxide, and the dirt can be washed off when it rains, so that the surface maintains the original glossy beauty , and has a bactericidal effect at the same time. [0004] In addition, it is also recommended to add copper and silver components on the basis of titanium oxide ...
