Background technology
Polished brick in porcelain character is a kind of building and ornament materials commonly used, and advantage such as firm, attractive in appearance and cheapness is used widely in each fields such as factory building, communal facility and house fitting-ups with it, is to use one of material of construction the most widely.But polished brick in porcelain character also exposes the shortcoming of vulnerable to pollution in the life-time service process, in use owing to rainwater, contain the infecting of pollutents such as solution of coloured solvent, the polished brick in porcelain character surface is formed remove not fall, nonvolatil stain, and as time passes, the problem that the brick surface polishing layer wearing and tearing, luminance brightness decline can occur even cause the brick body to damage influences attractive in appearance and use.
The major cause of the problems referred to above is because in brick body sintering procedure due to the residual pore and fine crack absorb polluted matter.Polished brick in porcelain character is after burning till, true porosity in the base substrate, apparent porosity and sealed porosity rate can change to some extent along with the variation of maximum sintering temperature, burn till just apparent porosity decline of back, up near 0, the sealed porosity rate is then always about more than 8%, improve firing temperature and can only reduce apparent porosity, and sealed porosity rate even after apparent porosity disappears, also can continue to rise.These sealed porositys will be exposed on the surface of brick after polishing, and when pollutent touched polished tile surperficial, a part of pollutent will penetrate in the sealed porosity of exposure, form stain.In the base substrate of the quick baking into porcelain polished tile of low temperature, because its main component coefficient of expansion quartzy and glassy phase differs greatly, if quartz particles is excessive, glassy phase can be subjected to big tension stress and cracks when then cooling off, and has many tiny cracks in the adobe.In polishing process, adobe is through after corase grind, fine grinding and three stressed operations of polishing, under the effect of the powerful external force of grinding tool, make tiny crack in the adobe that in various degree expansion (if original tiny crack is bigger, adobe fracture, damaged phenomenon will take place) all be arranged.Therefore, polished surface is a surface that is worn that is covered with many fine cracks, fall the polished surface of polished tile when pollutent after, a part of pollutent will be penetrated in various crackles, causes the polished tile anti-fouling ability.
The main component of common pollution substance is made up of colored inorganics of water-soluble solubility or organism.Because the complicacy of pollutant component in the daily life, therefore anti-pollution material will have versatility, at first want the hydrophilic material of right and wrong, next is acidproof, alkali-proof material, to ordinary organic solvents (as hexylene glycol, glycerine, gasoline, kerosene) be difficult for moltenly, should have perviousness in addition or easily be adsorbed in the surface of adobe.The anti-soil principle of existing stain control agent is to utilize the solid surface modification technology to reach antifouling purpose.Surface modification is to utilize structure and the character of solid surface characterization of adsorption by various surface treatments change solid surface, to adapt to the requirement of various expections.Antifouling material also is a surfactant; adobe through surface modification; stain control agent relies on wicking action to infiltrate product surface pore and tiny crack; under the effect of water in air branch and oxygen; can in the suitable time, combine with adobe generation physical chemistry; form and the good weather resistance soiling protective layer of product consistency, adobe just has antifouling effect like this.
The polished tile stain control agent mainly is silica type and paraffin wax emulsions class on the market, home and abroad at present.The coating filming equipment of this class stain control agent all adopts a kind of like this technology now at home, outward: add the even processing method of anti-fouling material → brushing → throwing.Adopt existing stain control agent and antifouling brushing equipment, the ceramic polished brick surface soiling film that processes antifouling indifferent, the poor durability of antifouling film, this is ceramic green business men ubiquity, be badly in need of the difficult problem that solves.Existing stain control agent does not have the function of blast.
