Example Embodiment

[0024] Example 1 The nano-stone antibacterial agent of the present invention and its production method.

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

Example Embodiment

[0026] Example 2 Double composition stone surface protective agent.

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

Example Embodiment

[0028] Example 3 A nano stone antibacterial agent and a manufacturing process of waterproof, antifouling and antibacterial nano stone.

[0029] Dilute the mother liquor of advanced interior eco-nano paint with deionized water into a dispersion with 5-10% solid content, add 0.2% by weight of Triton X-100, 3% by weight of nano-silver sterilizing material HTB-03 and nano-oxidation Zinc HTZn-03 1% by weight. Mechanical stirring is made into nano-dispersed emulsion and made into penetrating antibacterial agent.

[0030] Coat the penetrating antibacterial agent on the stone surface, keep the dispersed emulsion moisturizing for 20-30 minutes, and wipe the surface of the dispersed emulsion with a damp cloth. Dry for 12-24 hours at ambient temperature, and then apply the stone protective agent prepared in Example 2 horizontally and vertically. After standing for solidification and drying, the waterproof, antifouling and antibacterial nano stone material of the present invention is obtained...

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...
