Problems solved by technology

However, the principle of the matting agent is to react to generate hydrogen fluoride, sulfuric acid, etc. to corrode the brick surface and form a dull surface. The treatment process is highly corrosive and will reduce the antifouling performance of the product.
The raw material of the matting agent is complicated, and it cannot play the role of hole filling

Embodiment 1

[0032] Polish the tile surface to a glossiness of 55 degrees;

[0033] According to mass ratio silica sol (Foshan Shenghai Huagong Technology Co., Ltd. JN-30 model, pH is 9, concentration 20wt%, particle size 15nm): water: precipitation method silica (Guangzhou Zhuofan Chemical Co., Ltd. model M-5 , particle diameter 40nm)=1:1:0.3 prepare matting hole filling agent to fill holes;

[0034] Specific steps:

[0035] 1) When polishing, directly wash and clean the surface polishing powder online, and use the first group of grinding heads of the matting hole filling equipment to directly polish the brick surface to remove water and keep the brick surface clean;

[0036] 2) Use 10 sets of grinding heads equipped with rubber pads to grind and apply a matting hole filling agent to fill the holes. The amount of coating is 18 g / m 2 ;

[0037] 3) When coating, due to the effect of friction, the highest temperature on the brick surface will reach 80 degrees, and the matting and filling...

Embodiment 2

[0041] Polish the tile surface to a glossiness of 50 degrees;

[0042] According to mass ratio silica sol (Foshan Shenghai Huagong Technology Co., Ltd. JN-20 type, pH is 10, concentration 16wt%, particle size 12nm): water: fumed silica (Guangzhou Zhuofan Chemical Co., Ltd. model LM-130 , particle size 20nm) = 1:1:0.2 to prepare a matting hole-filling agent. The hole filling method is the same as Example 1, and the coating amount is 13 g / m 2 ;

[0043] Finally, apply antifouling wax, and measure the surface gloss of the ceramic tile to be 61 degrees.

Embodiment 3

[0045] Polish the tile surface to a glossiness of 45 degrees;

[0046] According to the mass ratio of silica sol (Foshan Shenghai Huagong Technology Co., Ltd. JN-40 model, pH is 9.5, concentration 22wt%, particle size 18nm): water: matting agent = 1:1:0.8 to prepare matting hole filling agent for hole filling , wherein the matting agent is a mixture of precipitated silica (Guangzhou Zhuofan Chemical Co., Ltd. model M-5, particle size 40nm) and fumed silica (Guangzhou Zhuofan Chemical Co., Ltd. model LM-150, particle size 50nm) , the mass ratio of the two is 1:1;

[0047] The hole filling method is the same as Example 1, and the coating amount is 10 g / m 2 ;

[0048] Finally, apply antifouling wax, and measure the surface gloss of the ceramic tile to be 55 degrees.

Abstract

The invention relates to a matte pore-filling agent and a using method thereof. The matte pore-filling agent comprises a silica solution and a matting agent in a mass ratio of 1: (0.2-0.8). In the invention, the stone glossiness of an obtained product can reach below 70 degrees, and the antifouling effect is good.

Description

technical field [0001] The invention belongs to the technical field of ceramic cold processing, in particular to a matting hole filling agent and a method for using the same, and belongs to the field of architectural ceramic decoration. Background technique [0002] Polished tiles are favored and loved by consumers because of their bright mirror-like surface and rich and varied colors. However, due to the presence of fine pores (4-5% closed pores) on the surface of the polished tiles, these fine pores will be exposed to the surface of the ceramic tile after polishing to form open pores. At the same time, because the glass phase of the polished brick body accounts for about 50% to 60%, the others are quartz, mullite and pores. Since the expansion coefficients of the quartz and glass phases are very different, if the quartz particles are too large, the glass phase will be subjected to large tensile stress during cooling and cracks will occur, and even the cracks in the adobe ...
