Also, the present invention provides an organic / inorganic composite waterproofing material which imparts adhesiveness and high elasticity to absorb cracks and impacts.

Also, in order to provide a uniform quality waterproofing material, calcium carbonate is used instead of the cement waterproofing material in which the conventional cracks are generated, so that the waterproofing material is uniformly manufactured.

In addition, since the waste shell and styrofoam are recycled and used in the waterproofing material, an environmentally friendly waterproofing material is desired to provide a more uniform and easy-to-install waterproofing material.

1 is a flowchart of a method for manufacturing a one-pack type organic / inorganic composite waterproofing material according to the present invention.

The term "waterproofing material" used in the present invention refers to a one-part type ready-to-use material used for waterproofing, and "waterproofing agent" means a waterproofing agent having two- Is used as a material for manufacturing. In the present invention, the component content is expressed as wt% (wt%).

The present invention solves the problem that the polymer cement waterproofing layer of the prior art has a problem of quick drying and cracking and a problem that the quality of the coating film is not uniform because the mixing ratio is not constant according to the constructor using the waterproofing agent.

The problem of quick drying and cracking is the improvement of the adhesive component, and the vinyl epoxy and the redispersible resin are used to give adhesiveness and high elasticity.

In order to solve the cracking problem of cement waterproof layer, instead of using cement and sand, calcium carbonate and shell powder are used to form a coating having density and thickness.

The present invention includes a styrene butadiene-based compound as a main component. The styrene-butadiene-based compound is a main polymeric synthetic resin main component according to the present invention and contains 20 to 50% by weight. As used herein, the styrene-butadiene-based compound is included in a larger amount than the other components.

  The styrene-butadiene-based compound is not particularly limited and may include styrene butadiene or a derivative thereof. Among them, styrene butadiene dispersion, styrene-butadiene-carboxylate styrene-butadiene and styrene butadiene And rubber (SBR).

In the present invention, a vinyl epoxy is used to impart adhesiveness and high elasticity to prevent concrete from being cracked or damaged by impact. Vinyl epoxy enhances waterproofing and maintains adhesion even under temperature changes. The preferred component content is 5-20% by weight.

2 to 5% by weight of a copolymer of vinyl acetate, vinyl buttate and ethylene (vinyl acetate, vinyl versatate and ethylene) is used as a redispersible resin (Iloxec FX3300). The redispersible resin has excellent adhesion and fluidity, which reduces cracks and improves workability. It also increases the resistance to freezing and thawing, increases plasticity and flexibility, and is easily dispersed in water to provide stability in the production of mortar.

Another feature of the present invention includes 1 to 2% by weight of carbon black. Carbon black is used as a reinforcing material for reinforcing the elasticity of rubber or as a coloring agent for ink, but in the present invention, it serves as a thermal barrier material. Because heat rays in sunlight are infrared rays, carbon black is known to absorb visible light but reflect infrared light and have heat shielding properties.

The plasticizer may be selected from a phthalic acid type, a trimellitic acid type, an epoxy type, a polyester type, an aliphatic type, an antioxidative type or a combination of two or more thereof. The plasticizer is preferably a liquid material which improves the plasticity of the liquid paint without the absorption of moisture. Among them, a plasticizer (Plastilit 3060) produced by BASF, which has high quality and reliability of properties, is preferably used.

Defoamer is a liquid defoamer with 100% active ingredient and widely used for synthetic latex, emulsion based paint, adhesive, construction putty. Not only exhibits excellent defoaming property against the latex emulsion, but also exhibits excellent effect and suppression effect on the acrylic, vinyl acetate and vinyl acetate acrylic emulsions.

A dispersant is a substance that is added to prevent aggregation of fine particles. Adsorbing materials such as surfactants and high molecular materials are used. Peptizers are also included in the dispersant.

In the present invention, the antifoaming agent, preservative and dispersant are each preferably 0.5 to 2% by weight.

Waterglass is used in 3 ~ 10% by weight to fill the pores of waterproofing and concrete, to strengthen the strength, to accelerate the drying of the waterproofing agent, and to strengthen the water of the base surface so that the waterproof layer does not fall off.

In the present invention, calcium carbonate (CaCO ₃ ) is used in an amount of 15 to 30% by weight so that the density and the thickness of the waterproof layer are formed instead of cement and sand for the one-component type waterproofing material. Calcium carbonate is used as a powder by crushing into main components such as marble, calcite, beryl, limestone, chalk, gypsum, shell, egg shell and coral.

Shell shells and shells are mainly composed of calcium carbonate, the waste is not decomposed and piled up, undermining the environment. In order to solve the environmental pollution and increase the recycling efficiency, the present invention uses 3 to 10%

In the present invention, styrofoam powder is used in an amount of 5 to 10% by weight in order to impart heat insulation and make eco-friendly recyclable resources. Styrofoam powder is collected at a construction site or a styrofoam production plant to remove foreign matter from a recycling plant and fused at 180 ° C to 200 ° C in a reduced pressure vessel to make an ingot. The ingot is cooled, pulverized and pulverized into 150 mesh to 180 mesh do.
