The composition of the two-component tile adhesive having the antimicrobial properties and elasticity,

35 to 45 wt% white portland cement; 10-20 wt% of 60-200 mesh silica sand; 35-40% by weight of any one of the mineral powder consisting of minerals generating anions added to impart functionality and activated ocher powder powder activated to emit far infrared rays, or powdered materials for mixed functionality; 0.3-1.5 wt% of methyl cellulose; 1-5% by weight of cellulose fibers; Filler consisting of 8.7 to 17% by weight of the elastic functional material to give elasticity,

35-44 weight% of mixed resin (resin in which acrylic synthetic resin and SBR resin were mixed at a weight ratio of 3: (1 to 3), respectively); 0.2 to 1.0% by weight of methyl cellulose; 0.1-0.5 weight% of pH adjusters; 0.05 to 0.2 wt% preservative; Antifoaming agent 0.05 to 0.2% by weight; It is composed of a binder composed of 55.6 to 64% by weight of aqueous grass solution (a solution in which the grass herb solution and water are mixed in a weight ratio of 1: (3 to 6), respectively).

- Filler

As the white portland cement, one suitable for KS L 5204 may be used. However, when less than 35% by weight is added, the strength drops, and when more than 45% by weight is added, the pot life is shortened.

The silica sand is obtained by pulverizing the natural sand is preferably used that does not contain a foreign substance that can affect the curing of the cement.

The mineral powder is used as a tourmaline, monazite, zeolite, calcite alone or a mixture of minerals that generate a large amount of anions, usually the mineral powder is mixed in a weight ratio, tourmaline 20 to 30 parts by weight, monazite 22 ~ 45 It is preferably composed of 10 to 20 parts by weight of zeolite, 15 to 20 parts by weight of zeolite, and pulverization in a pulverizer and a mean particle size of 70 to 100 mesh through a strainer. In other words, the mineral powder is mixed with 20 to 30 kg of tourmaline, 22 to 45 kg of monazite, 10 to 20 kg of zeolite, and 15 to 20 kg of serpentine.

The ocher powder uses activated ocher powder, and the method of activating the ocher powder is pulverized by quenching using pure water or air at high temperature (600-900 ° C.), followed by quenching using water or air. It is desirable to have a particle size of 100 to 200 meshes. When heating the high temperature loess as described above can remove the microorganisms present in the loess, there is also an effect of increasing the effect of the emission of far infrared.

Any one selected from the mineral powder consisting of the mineral generating the anion and the activated ocher powder powder activated to emit far infrared rays or the powder material for mixed functionality is usually 30 to 70% by weight of the mineral powder and activated ocher powder It is preferable that it consists of 30 to 70 weight% of powders.

The methyl cellulose is added to the filler as a cellulose derivative to exhibit adhesive strength and water retention. If less than 0.3% by weight, the slippage of the tile and the water retention rate occur due to a decrease in viscosity, and when the content exceeds 1.5% by weight, the viscosity increases too much. It is not suitable for tile adhesive due to its poor castle property. Therefore, methylcellulose should be added 0.3 to 1.5% by weight.

The cellulose fiber is added to the present invention serves to improve crack resistance and tile slip resistance. If less than 1% by weight, cracks or tile slip may occur. If more than 5% by weight, the product becomes rough after mixing and the viscosity rises rapidly, thereby reducing the pot life. Therefore, it is preferable to add at 1 to 5 weight%.

The elastic functional material is added to 8.7 to 17% by weight to have elasticity. When it is less than 7% by weight, sufficient elasticity or the like cannot be obtained, and when it is more than 17% by weight, slip resistance may be degraded, which may cause a problem in its function.

The elastic functional material is VA-VV-EAC (Vinyl Acetate, Vinyl Versatate, Ethylene, Butyl Acrylate) four-polymer reemulsified powder resin 60-88% by weight; 10-30% by weight of metakaolin; SILANE POWDER is composed of 2 ~ 10 wt%.

The re-emulsified powder resin is a material that has adhesive strength, bending strength, elasticity with cement, VAE (Vinyl Acetate Ethylen) re-emulsified powder resin and acrylic-based re-emulsified powder resin are generally required a lot of water resistance and heat resistance VA-VV-E-AC (Vinyl Acetate, Vinyl Versatate, Ethylene, Butyl Acrylate) 4 Copolymer Reemulsified Powder Resin due to the decrease in the adhesive strength and heat resistance of polished tiles in saunas, saunas, swimming pools and public baths. It is preferable to use.

The VA-VV-E-AC (vinyl acetate, vinyl versatate, ethylene, butyl acrylate) 4 copolymer re-emulsified powder resin sprays a liquid emulsion made by copolymerizing vinyl acetate, vinyl versatate, ethylene, butyl acrylate with a spray. It is dried and powdered product.

The metakaolin is a material that serves to improve the water-resistant adhesive strength with cement.

The SILANE POWDER is a material that plays a role of improving the water-resistant adhesive strength with cement, it is preferable to use a product having an average particle size of 300㎛, the apparent specific gravity of 600g / L.

-Binders

The mixed resin is formed by mixing acrylic synthetic resin and SBR resin in a ratio of 3: (1 to 3), respectively. When the mixing ratio of acrylic synthetic resin and SBR resin is less than 3: 1, tile slipping phenomenon and workability are inferior, and when it is larger than 3: 3, the product becomes rough, adhesiveness, workability, adhesive strength and tile slipping phenomenon also occur. .

The acrylic synthetic resin is a styrene-acrylic copolymer synthetic resin emulsion containing a solid content of 45% by weight or more, the acrylic monomer 2-ethylhexyl acrylate (2-EHA), acrylic acid (AA), methacryl Resin using any one or more of an acid (methacrylic acid (MAA), methyl methacrylate (MMA)) is used.

The SBR resin is a solid content of 45% by weight or more, butadiene 75%: styrene 25% structure with a rubber component containing 60 to 70%.

The pH adjusting agent is used to adjust the acidity (pH) of the entire composition as a strong base material such as ammonium hydroxide.

As the preservative, benzoic acid, salicylic acid, formalin, or the like may be used. However, formalin is very irritating to humans and should be avoided if possible. The two-component high-performance tile adhesive with excellent water resistance and elasticity uses natural products to improve the thickening and adhesion. Therefore, when the temperature and humidity are high in the summer, it may decay and deteriorate by microorganisms, so an appropriate amount of preservative must be added.

As the antifoaming agent to suppress the foaming, commercialized products such as conventional nonionic oil in water type (O / W) emulsions such as polyether-siloxane copolymers containing hydrophobic silica may be used.

The aqueous herb solution used as the diluting solvent has a bactericidal and antimicrobial effect, and the aqueous herb solution is formed by mixing a ratio of 3 to 6 water to wood herb solution 1 by weight. After liquefied and collected, it is preferable to use it for more than 6 months to remove toxic and harmful substances.

The aqueous herb solution used as the diluting solvent may be used to add an extract of cypress leaves excellent in insect repellent and antibacterial activity in order to improve its functionality.

The cypress leaf extract is usually preferably added 10 to 20% by weight relative to the weight of the aqueous herb solution. That is, a mixture of 10-20% by weight of cypress leaf extract may be used as a diluting solvent in 80-90% by weight of aqueous solution consisting of wood vinegar and water.

The preparation method of the extract of the cypress tree leaf is provided in detail in (KR) Patent Publication No. 10-964027, and the present invention does not describe the preparation method of the extract of the cypress tree leaf.
