Described a kind of imitative ceramic tile exterior wall sand wall texture coating that contains silica-based activity gel, described silica sand is generated through operations such as pulverizing, grinding, washing, oven dry, screenings by natural crystal, below 150 orders.

Described a kind of imitative ceramic tile exterior wall sand wall texture coating that contains silica-based activity gel, emulsion adopt texture to coat with lacquer special-purpose pure-acrylic emulsion, and water-fast anti-yellowing property is good.

A kind of preparation method who contains the imitative ceramic tile exterior wall sand wall texture coating of silica-based activity gel, said coating is that the mass percent by following raw material mixes: water 10-20%, emulsion 20-30%, auxiliary agent 10-15%, silica sand 40-50%, silica-based activity gel 1-5%; Said silica-based activity gel is the HG-5 type, and pH value is at 6-8, and viscosity is at the white thick of 4000-6000cps (Viscosity is high, mobile extreme difference )Liquid;

The preparation method of said coating comprises the steps:

1) with water, auxiliary agent low speed (100-300 rev/min) mixing by weight proportion 10-15 minute, stirs pulping;

2) adding emulsion, HG-5 low speed (100-300 rev/min) in the above-mentioned slurry stirs and mixed in 10-15 minute;

3) slurry that modulates is imported in the texture jar special, drop into silica sand, stir, toning;

4) check, storehouse dress.

Advantage of the present invention and effect are:

1. the present invention compares with existing ceramic tile intimating construction coating, and the interpolation of silica-based activity gel can improve the texture coating thixotropy, makes construction more smooth.

2. the interpolation of the silica-based activity gel HG-5 of the present invention type can improve the application property of texture coating, and is time saving and energy saving.

3. the interpolation of the silica-based activity gel HG-5 of the present invention type makes coating have excellent in storage stability and the fullness ratio that increases coating.

4. the invention enables construction easily, expense reduces, and has the same stereoscopic sensation of similar ceramic tile, and decorative effect is strong.

5. the present invention has with countless changes three-dimensional texture, individual character collocation variation, and whole structure is abundant and lively, and the wall body coating of smooth type is improved to the concavo-convex coating of natural environmental-protective type.

6. the present invention can substitute ceramic tile, environmental protection more, and economy can represent personalization.And coating itself is radiationless, and from heavy and light, effect is true to nature, can create special decorative effect through different construction technologies, gimmick and skill.In Highrise buildings, high-grade villa, use more noticeablely, it has been avoided decorating coming off with age of bringing with ceramic tile from heavy and light, characteristics that sticking power is good and has jeopardized the danger of personnel safety.Both having improved the security of decoration of exterior wall, and increased its decorative effect again, is a kind of economic, practical decoration of exterior wall structure.

7. the densification of filming of product of the present invention, soft tough and tensile, impervious good, integral construction full coat covering wall forms whippy superior waterproof layer, has solved the disadvantage of the easy seepage of sticking brick fully.
