Embodiment 1

[0024] Embodiment 1 Nano-stone antibacterial agent of the present invention and its preparation method.

[0025] After diluting the nano-scale polyacrylate emulsion with deionized water to a dispersion liquid with a concentration of 5-10% (solid content), add 0.2-0.5% of non-ionic surfactant, 1-3% of silver-loaded nano-phosphate double salt, Nano-level zinc oxide 1-3%, stirring and dispersing into an emulsion, that is, obtaining a nano-stone antibacterial agent.

Embodiment 2

[0026] Example 2 Two-component stone surface protection agent.

[0027] Mix 20 parts of methyl hydrogen-containing silicone oil and 80 parts of No. 200 mineral spirits evenly, and use it as reserve A liquid. In addition, 6 parts of tetraisopropyl titanate and 94 parts of No. 200 mineral spirits were mixed evenly to form B liquid. When using, mix A and B liquid phases with equal weight or volume ratio, and use up within 4-8 hours.

Embodiment 3

[0028] Embodiment 3 A nano-stone antibacterial agent and a manufacturing process of waterproof, anti-fouling, and anti-bacterial nano-stone.

[0029] Dilute the high-grade interior wall ecological nano-paint mother liquor with deionized water into a dispersion with a solid content of 5-10%, add Triton X-100 0.2% by weight, nano silver-loaded bactericidal material HTB-03 3% by weight and nano-oxidized Zinc HTZn-03 1% by weight. Mechanical stirring is used to make nano-dispersed emulsion, which is made into penetrating antibacterial agent.

[0030] Apply the penetrating antibacterial agent on the surface of the stone, disperse the emulsion to moisturize for 20-30 minutes, and wipe the surface with a damp cloth to disperse the emulsion. Dry at ambient temperature for 12-24 hours, and then paint horizontally and vertically with the stone protective agent prepared in Example 2. After standing, solidifying and drying, the waterproof, antifouling and antibacterial nano stone materi...

Abstract

A nano-class surface protecting agent for stone material is composed of the antibacterial agent prepared from nano composite phosphate carrying Ag, nano zinc oxide, nano-class polyacrylate emulsion and emulsifier and the surface protecting agent which is the hydrogen-contained methyl silica oil containing tetraisopropyl titanate as coupling agent. A water-proof dirt-resistant antibacterial stone is prepared through coating said antibacterial agent, holding the liquid for 20-30 min, wiping it, drying and coating said surface protecting agent.

Description

technical field [0001] The invention belongs to the field of nano-coatings, in particular to a stone surface protective functional agent, in particular to a method for making waterproof, antifouling, antibacterial and antibacterial building stones. Background technique [0002] Natural marble and granite are widely used in building materials for their durability, elegance and elegance. However, natural stones that have been cut and polished generally have cracks and capillary pores, which are easy to absorb water, pollutants and corrosive gases in the atmosphere. After decoration or even before the completion of the decoration project, various stone lesions occur, such as water spots, yellowing, Bianian alkali, fresh moss or mildew spots, and various immersion pollution, which cause the original bright stone to lose its decorative effect. And treatment is very difficult, the best way to solve the problem is to carry out pre-protective treatment of stone, to limit the adsorpt...
