Clay brick, forms through pug process, shaping, dry and roasting for main raw material with clay (comprising the powder such as shale, coal gangue).Clay brick is gathered materials on the spot, low price, durable in use, also has the advantages such as fire prevention, heat insulation, sound insulation, the moisture absorption, uses extensive in civil construction project.In the upgrading process of city, a large amount of clay bricks can be removed.How these discarded clay bricks are manufactured a kind of imitative brick coating, old clay brick utilization of waste material being got up, is the problem that applicant thinks deeply and want solution.

Summary of the invention

In order to solve prior art Problems existing, the invention provides a kind of ecologic coating mainly utilizing old clay brick to make.

For achieving the above object, the technical solution used in the present invention is: a kind of ecologic coating reclaiming old clay brick and manufacture, and this ecologic coating comprises following component and weight percentage: the particle 40 ~ 60% formed after old clay brick cutting and grinding; Convex-concave rod powder 10 ~ 20%; Titanium dioxide 10 ~ 15%; Dicalcium powder 10%; Polyvinyl alcohol 5 ~ 8%; Vltra tears 3 ~ 5%; Each component concentration sum is 100%.

In the inventive solutions, convex-concave rod powder is with the powder-like product of high-quality attapulgite through processes such as ore dressing drying, abrasive dusts, and the stable chemical performance of the excellent powder of convex-concave, cohesive force is strong, adsorptive power is large.The sticking power between coating and body of wall can be increased.

Titanium dioxide (English name: titaniumdioxide), main component is the white pigment of titanium dioxide (TiO2).Titanium dioxide (TiO2) is a kind of polycrystalline compounds, and its particle is regularly arranged, has grid system, and the size of the water absorbability of titanium dioxide and its surface-area has certain relation, and surface-area is large, and water absorbability is high.

Water-ground limestone is called for short coarse whiting, and be raw material with the Wingdale of high-quality, be processed into white powder through lime pulverizing mill, its main component is CaCO3.Coarse whiting has that whiteness is high, purity good, form and aspect are soft and the feature such as chemical composition stability.Coarse whiting is typically used as filler, be widely used in the daily-use chemical industry industries such as artificial floor tile, rubber, plastics, papermaking, coating, paint, ink, cable, building product, food, medicine, weaving, feed, toothpaste, play the volume increasing product as weighting agent, reduce production cost.

Polyvinyl alcohol, organic compound, white plates, cotton-shaped or pulverulent solids, tasteless.Water-soluble (more than 95 DEG C), are insoluble to gasoline, kerosene, vegetables oil, benzene, toluene, ethylene dichloride, tetracol phenixin, acetone, vinyl acetic monomer, methyl alcohol, ethylene glycol etc.Be slightly soluble in dimethyl sulfoxide (DMSO).Polyvinyl alcohol is important industrial chemicals, for the manufacture of polyvinyl acetal, resistance to gasoline pipeline and vinylon synthon, fabric-treating agent, emulsifying agent, paper coating, tackiness agent, glue etc.

Vltra tears, has another name called hypromellose, HPMC, is to select the gossypin of high purity as raw material, obtains in the basic conditions through special etherificate.In construction industry industry, make mortar have pumping as the water-holding agent of sand-cement slurry, retardant.At slurry of plastering, gypsum material, putty powder or other building materials as tamanori, improve smear and extend operable time.As sticking brick, marble, decorative plastic, paste toughener, can also cement consumption be reduced.The water retention property of Vltra tears makes slurry because of so dry that to chap too soon, can not strengthen the rear intensity of sclerosis after smearing.
