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 technique of this process is very clear to those skilled in the art.

[0020] In general, paint components are composed of "coating film forming components" vehicles (vehicles) and "pigment components".

[0021] As a "coating film forming component", a vehicle is equivalent to a clear paint, and can disperse pigments, etc., and at the same time improve the fluidity of the paint. As for the "pigment component", it is a 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] Coating of the present invention constitutes:

[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 is a pigment component having an acrylic resin emulsion or a vinyl acetate emulsion capable of di...

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, especially to the coating film forming components of the coating, specifically a coating made of coal ash. [Background technique] [0002] As shown in Japanese Patent Application Laid-Open No. 56-131693, there is an increasing demand for coatings that mix coal ash powder and slurry, and that add various functions to achieve more added value. [0003] For example, after using titanium oxide for surface processing, photocatalyst reaction will occur when light (ultraviolet rays) shines, and the organic matter attached to the surface is oxidized and decomposed into water and carbon dioxide. The dirt can be washed away when it rains, so that the surface maintains its original luster and beauty , and has a bactericidal effect at the same time. [0004] In addition, it is also suggested to add copper and silver components on the basis of titanium oxide to improve the sterilization effect, ...
