Description

TECHNICAL FIELD [0001] The present invention relates to a waterproofing material, a method of manufacturing the same, and a method of constructing the same. [0002]

The present invention relates to a waterproofing agent technology, and more particularly, to a waterproofing agent for light reflection heat insulation panel for sloped roofs which can reduce energy by blocking heat transfer to the inside or outside of buildings and improve waterproofing and durability, ≪ / RTI >

Generally, waterproofing work for moisture and heat shielding is essential because the building is repeated every summer and winter, and the penetration water is frozen or corroded due to the temperature change, and deterioration due to atmospheric and light.

In the maintenance of the building, the waterproofing work should be performed after removing the existing waterproof layer. In the liquid waterproofing, the penetration water is poured 1 to 3 mm from the surface layer, Since the outside is corroded, it should be done after removing rust and corrosion parts.

The waterproofing works for this purpose are applied according to the situation such as asphalt waterproofing method, sheet waterproofing method, film waterproofing method, urethane waterproofing method, and composite waterproofing method in which each of these is laminated in accordance with the constituent parts of the building, .

The asphalt waterproofing method has been used for the longest time, and it is waterproof, but it is complicated and complicated to use the sand or sheet paper and heat to prevent the flow of the asphalt oil.

In the sheet waterproofing method, synthetic rubber or the like is made into a sheet having a certain thickness and width, and is adhered to a waterproof surface at a construction site to form a waterproof layer. However, there is a problem in that it is difficult to apply to complex parts, the water tightness in the seam between the sheets is poor, and the manual work for watertightness is required.

The coating film waterproofing method mainly uses epoxy, urethane, acrylic resin or asphalt as the main material, and organic solvent is mixed as a diluent. However, volatile organic solvents such as VOC and formaldehyde are used, which are harmful to human body, have a bad smell, are not environmentally friendly, and are flammable, which is a dangerous problem.

The urethane waterproofing method is to obtain a waterproof effect by arranging the bottom of a part to be applied, applying a primer thereto, sufficiently penetrating and drying it, and applying a liquid urethane resin to the bottom surface to form a urethane coating. Although it has the advantage of good adhesion with concrete surface and excellent elasticity, it can maintain waterproofness to a certain degree at cracking. However, it is difficult to fundamentally solve cracks when it is adhered to the bottom surface, and severe temperature change, moisture evaporation of concrete, There is a problem that the waterproof property and the durability of the building are deteriorated due to the occurrence of the bulging phenomenon of the cracks of the concrete, the damaged urethane coating film, and the continuous uplifting phenomenon.

Patent Document 1 discloses that a one-pack type elastic heat-and-waterproofing agent is produced by sequentially adding water and a dispersing agent, a synthetic resin, iron oxide, a light ceramic, a sericite and a thickening agent, A waterproofing agent, a waterproofing agent, a waterproofing agent, an odorless waterproofing agent, a waterproofing agent, an odorless waterproofing agent and a moldy waterproofing agent.

However, since the above-mentioned prior art has some waterproof performance, it has poor corrosion resistance and durability, and the heat shielding and insulation performance is not good. Therefore, it is easy to flow the external heat into the building and the internal heat out of the building, The efficiency is lowered, and the heat island effect in the city is intensified.
