preparation example Construction
[0030] A preparation process of anti-fouling and anti-skid bricks, comprising the following steps:
[0031] A. Polish the semi-finished brick body, and apply antifouling liquid on the surface of the brick body after polishing;
[0032] B. Coating with anti-slip liquid that has corrosive properties to bricks;
[0033] C. When the anti-slip liquid in step B is not dry, apply an anti-fouling colloid solution to form a film on the surface of the brick body after drying to obtain an anti-fouling and anti-slip brick.
[0034] After the semi-finished brick body is polished, it has two characteristics. First, the surface of the polished brick body will reveal frizzy pores. Second, the temperature of the polished brick surface will increase.
[0035] According to the first feature, the application is coated with antifouling liquid after polishing, such as figure 1 shown ( figure 1 The brick body in the middle is the structural schematic diagram of the brick body section under the mi...
Embodiment 1
[0045] Select polished tiles after molding, drying, printing, firing and rough polishing as semi-finished brick bodies;
[0046] A. Polish the semi-finished brick body, and apply hydrogen-containing silicone oil on the surface of the brick body after polishing;
[0047] B, coating carbonic acid solution, concentration is 30%;
[0048] C. Before the fruit acid water-based liquid is completely dry (generally after coating the carbonic acid solution with a concentration of 30% and staying for 90 seconds, apply the acid colloid), apply the acid colloid (sodium methyl silicate), and form on the surface of the brick body Thin film, to obtain a polished tile with a brightness of 75 and a coefficient of friction of 0.72. There is no obvious difference between its gloss and the polished tiles on the market with the naked eye.
[0049] Antifouling performance test: (1) pass the red and blue ink test, no trace; (2) pass the red, blue and black oil-based pen test, no trace (three-level ant...
Embodiment 2
[0051] Choose polished bricks after molding, drying, printing, firing, and rough polishing as semi-finished bricks;
[0052] A. Polish the semi-finished brick body, and apply hydrogen-containing silicone oil on the surface of the brick body after polishing;
[0053] B, coating acidic colloid (sodium methyl silicate);
[0054] C. Before the acidic colloid is dried to form a film, apply a carbonic acid solution with a concentration of 30% to form a film on the surface of the brick body to obtain a polished brick. The brightness of the brick surface is 62, and the friction coefficient is 0.61. There is a noticeable difference in gloss.
[0055] From the comparison of Examples 1 and 2, it is known that when the anti-slip liquid and the anti-fouling colloidal solution are coated in the opposite order, the brightness of the obtained brick body is inconsistent. There is no obvious difference in the polished tiles to the naked eye, and the polished tiles obtained in Example 2, even ...
