Problems solved by technology

[0004] However, when using the existing solvent-based antifouling liquid, it is necessary to wait until the surface of the tile is isolated from the air for several hours, and then it can be packaged and put into storage after it is completely dry; otherwise, the antifouling liquid on the adjacent tiles will react and die Makes bricks stick together, thus becoming a waste product
In this way, it creates obstacles to continuous production and requires a large area of ​​space, which is not available in many factories, which greatly reduces the production efficiency of polished tiles.

Embodiment 1

[0024] At 25°C, first add 100 parts of No. 120 solvent gasoline and 4 parts of No. 200 solvent gasoline into the stirring tank by mass parts and stir for 1 minute to fully mix the solvent gasoline; then add 15 parts of high hydrogen-containing silicone oil, molecular formula for (CH 3 ) 3 Si0[(CH 3 )(H)Si0]nSi(CH 3 ) 3 , 0.5 parts of aminosilane and 3 parts of amino silicone oil, stirring continuously for 10 minutes, after the end of the gas evolution reaction, the required self-isolating antifouling agent can be obtained.

[0025] The self-isolated antifouling agent provided in this example is a solvent-based antifouling agent, by adding amino silicone oil to the solvent-based antifouling agent; when the solvent volatilizes, the amino group in the amino silicone oil participates in the bulk polymerization reaction and forms a Strong adhesion, while the three methyl groups in the amino silicone oil float to and cover the entire surface of the tile with the volatilization o...

Embodiment 2

[0027] At 35°C, first add 100 parts of No. 120 solvent gasoline and 4 parts of solvent gasoline D-40 to the stirring tank by mass parts and stir for 30 seconds to fully mix the solvent gasoline; then add 20 parts of high hydrogen-containing silicone oil, The molecular formula is (CH 3 ) 3 Si0[(CH 3 )(H)Si0]nSi(CH 3 ) 3 , 2.5 parts of aminosilane and 5 parts of amino silicone oil, stirring continuously for 20 minutes, until the gas is completely released and the reaction is completed, the required self-isolation antifouling agent can be obtained.

Embodiment 3

[0029] At 15°C, first add 100 parts of No. 120 solvent gasoline and 4 parts of solvent gasoline D-40 into the stirring tank by mass parts and stir for 30 seconds to fully mix the solvent gasoline; then add 20 parts of high hydrogen-containing silicone oil, The molecular formula is (CH 3 ) 3 Si0[(CH 3 )(H)Si0]nSi(CH 3 ) 3 , 2.5 parts of aminosilane, 3 parts of amino silicone oil and 2 parts of methyl silicone oil, and keep stirring for 60 minutes. After the gas release reaction is completed, the required self-isolation antifouling agent can be obtained.

[0030] In this embodiment, methyl silicone oil and amino silicone oil have the same function, not only participating in the bulk polymerization reaction but also spontaneously migrating to the surface to form a self-isolation layer. One advantage of adding methyl silicone oil at the same time is that the manufacturing cost of the antifouling agent can be appropriately reduced.

Abstract

The invention discloses a self-isolation type anti-fouling agent. The self-isolation type anti-fouling agent is characterized by being prepared from the following raw materials in parts by weight: 15-20 parts of hydrogen-containing silicone oil, 0.5-2.5 parts of amino silane, 800-100 parts of 120# solvent petroleum, 0-4 parts of 200# solvent petroleum, 0-4 parts of solvent petroleum D-40 and 3-5 parts of amino-silicone oil. Compared with the prior art, the self-isolation type anti-fouling agent has the advantages that the amino-silicone oil is added into the solvent type anti-fouling agent, when the solvent is volatilized, amino in the amino-silicone oil participates in body polymerization reaction and is firmly adhered with a ceramic tile, and three methyl in the amino-silicone oil is fluttered to and distributed to the surface of the whole ceramic tile along with volatilization of the solvent to form a self-insulation layer, so that the self-isolation type anti-fouling agent can be packaged and stored without drying for a long time, and therefore, production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of ceramic tile antifouling, in particular to a self-isolated antifouling agent. Background technique [0002] In the preparation process of polished tiles, when the tile body is polished, its surface layer is covered with capillary pores, which are easy to fill and absorb other solid particles, liquids, colloids, etc., thereby causing pollution. In order to improve the anti-fouling performance of polished tiles, it is necessary to coat the anti-fouling liquid on the surface of the tiles. [0003] At present, the common antifouling liquids mainly include water-emulsion type and solvent type. Among them, the water-emulsion antifouling liquid mainly uses the principle of physical filling to emulsify the hydrogen-containing silicone oil and fill the pores of the polished tile surface. Because it is purely physical filling, it has the disadvantages of low surface energy and poor penetration, and generally cann...
