Waterproofing agents currently used in various industries are known as follows.

Epoxy Waterproofing Agent

 It is used to repair and reinforce concrete cracks, bond steel plates, etc., and to repair floors, and to integrate epoxy and structure by injecting grouting to protect the concrete inside and prevent corrosion of reinforcing bars. Due to its physical properties, it does not have any elasticity at all, so when the concrete moves by heat, the waterproof construction site does not move together, and it is damaged.

In particular, when exposed to sunlight, yellowing, deterioration, and cracks occur, so they are not used for external exposure.

Asphalt mixing bentonite waterproofing agent

It is used to solve the lifting of the waterproof layer due to the behavior of the structure by combining the elasticity and expandability of bentonite with the adhesion and waterproofing of rubber asphalt. Asphalt waterproofing method uses the property that crack does not occur due to heat shrinkage phenomenon even if it is applied thinly on concrete surface according to bitumen property of asphalt. It is used by laminating roofing and felt, but it has the disadvantage of non-exposure method.

Polymer crystalline powder coating waterproofing agent

It is an inorganic and organic mixed penetration waterproofing agent composed of organic chemicals and cements. Hydrated and dissolved organic chemicals penetrate into the pores of concrete and cause chemical reactions to form insoluble organic crystals, forming a waterproof layer. When the concrete is moved by heat,

There is a disadvantage that can not move together.

Synthetic polymer sheet repellent

Synthetic rubber, resin, asphalt, etc. are used as the main raw materials, and a thin sheet of 2 ~ 3mm is formed using an adhesive or a torch to form a waterproof layer on the mother, but the adhesion is not perfect, and in case of leakage, partial repair is not easy and causes There are disadvantages that are hard to find.

Urethane film waterproofing agent

It has excellent strength and waterproof function of coating film, and has some elasticity (cushion function) and strong against external exposure, so it can treat urethane waterproofing solution on rooftops, ground track flooring materials, and car driving floors. Can be used However, there is a drawback of having to be installed more than 3mm due to permeability and breathability, and there is a drawback of not forming a waterproof film if the mixing ratio of the main material and the curing agent is not correct. No repair with the old coating.

Inorganic coating waterproofing agent

It is a method of forming a waterproof film by mixing cement and acrylic emulsion in an appropriate amount, but it has the advantage of not having adhesive strength and swelling shape.However, when a crack occurs in the mother body, there is no elasticity.

It does not move together and breaks, and there is a disadvantage that the winter emulsion can not be frozen.

In the present invention, it is possible to use an elastomeric elastomer resin selected from SBS (styrene-butadiene-styrene), SIS (styrene-isoprene-styrene), SEBS (styrene ethylene butadiene styrene), SEPS (styrene ethylene propylene styrene) , The elastomeric elastomer resin serves to increase the elasticity of the waterproof paint.

Since the elastomeric elastomer resin has thermoplastic and rubber properties, it is highly elastic and easy to restore to its original shape, and is a non-toxic soft copolymer that does not need to be heated because it is dissolved at room temperature, and does not need to be warmed, such as an emulsifier, an antifoaming agent, a curing agent, and a surfactant. It is the physical property that need not add an additive.

However, since elastomeric elastomeric resins are expensive, petroleum solvents can be used by dissolving an elastomeric resin in a petroleum solvent in order to ensure only the degree of high elasticity and elasticity among properties, and the elastomeric resin can be dissolved in a petroleum solvent. Kerosene ( kerosene ), light oil and the like can be used, and the most preferred solvent is normal hexane .

The nylon resin is a material added to enhance the adhesion and hardness of the waterproof paint, the preferred resin is nylon 66 monofilament resin, nylon 66 is not directly mixed with other compositions, so 250 degrees to dissolve it After dissolving in heat, it is used by dissolving in an aromatic hydrocarbon solvent, preferably any one of a combination of cocosol, chlorine, toluene, and solvent.

The dispersant serves to disperse the solid fine particles in the liquid. In the embodiment of the present invention, the dispersing agent is used to spray the whitening substance and the pigment in the liquid, and the dispersing agent preferably uses an oily dispersant.

In addition, in order for the microparticles of the solid dispersed by the dispersing agent to have a viscosity, it is preferable to use Gstealgimonium hectite or Zmethicone as a thickener. When the thickener is mixed as described above, the whitening material and the pigment have a viscosity in the solvent, and thus, an equal saturation and yellowing prevention can be expected.

In addition, in the waterproof paint of the present invention, it is preferable to mix 3-5 wt% of the pigment to the dye, and the most preferable ratio is 5 wt%.

Colored pigments are classified into inorganic pigments and organic pigments. Inorganic pigments are inorganic in color components, and the color is often unclear, but the hiding power is large and the heat / light resistance is excellent. Organic pigments are classified into natural pigments and synthetic pigments.They have lower physical properties such as heat resistance and light resistance than inorganic pigments, but they have a wide range of colors and are clear and have excellent coloring power. There is an advantage. Pigments are hue, vivid depending on the type

In addition, since hiding power, coloring power, color fastness, etc. are different, in the present invention, the pigment is not limited to any one, and optionally two or more pigments may be used in combination.

In contrast to the pigment forming an opaque colored film on the surface of the object in the powder state, the dye is dissolved in water and oil, dispersed as a single molecule and combined with the molecule to color. This dye is used as a colorant.
