However, toxic waterproofing often causes defects. If the waterproof construction is wrong, water leakage and flooding will occur in civil and building structures, and corrosion and damage to the finished structure will occur. Therefore, in the field of civil engineering and construction, the importance of waterproof construction is highlighted, and there is an urgent need for the emergence of excellent waterproofing materials capable of continuously exerting perfect waterproof functions until the disassembly of civil engineering and buildings with just one simple waterproof construction. .

In other words, the joints to which the polymer resin film sheet and one end of the sheet are connected are partially waterproofed in a holed state due to overheating of the torch lamp or the hot air or the polymer resin film sheet is melted due to low heat. If the waterproof construction is not completed in the state that the seat and the sheet is not completely connected and the waterproof construction is completed, water leakage may occur, thereby providing a cause of the waterproof construction defect.

The point / adhesive of the present invention has a high viscosity of 97-99% and exhibits a porridge state at a high temperature of 100 ° C. or higher, but when cooled, the shape at room temperature is hardened into a very tough rubber form. While exhibiting adhesiveness, it has a property of exhibiting strong adhesiveness, and the adhesive agent which shares such adhesiveness and adhesiveness, such as PP, PE, PVC, EVA, urethane, etc. By applying the film on the upper and lower parts of the film sheet, a good polymer synthetic resin film sheet waterproof material (waterproof sheet) is produced.

According to the present invention, the point and the adhesive are integrally bonded to the polymer synthetic resin film sheet at the upper and lower portions of the polymer synthetic resin film sheets (PP, PE, EVA, PVC, and urethane). The joint is easily bonded and integrated, and it has excellent adhesion with the base concrete surface, which is the adherend, and excellent adhesion with foam sheets such as cement mortar, PP and PE, which are waterproof layer protection agents. The waterproof sheet of the sheet achieves the effect of completely waterproofing the entire area in one piece.

The composition of the adhesive agent according to the embodiment of the present invention is as follows.

Solvent oil: Rape Seed Oil ..... 100g (%)

Elastomer TPE: One of SBS and SIS ............. 40g (%)

Tackifier: Petroleum Resin ...... 18g (%)

Rosin ......................................... 13g (%)

Modified phenol resins (phenol-Formaldehyde resin). ... 8 g (%)

Thermal Stabilizer: Aluminum stearate ....... 3g (%)

                Barium stearate ........... 1g (%)

Aging inhibitor: PA (phenyl-?-Naphthylamine) ......... 1.5g (%) DCD (Substituted diphenylamine) ......... ... 1,5 g (%)

Trimethyl dihydroquinoline (RD) ... 1,3 g (%)

Reinforcement: White carbon ....................... 15g (%)

Zinc Oxide ......... 5 g (%)

Filler: Caolin ............ 30g (%)

Activated Clay ..... 10g (%)

The embodiment of the present invention as described above is an example, wherein the adhesive agent is a large amount in order to dissolve SBS or SIS, which is a rubber-like elastomer (elastomer) in a mineral or vegetable oil, and impart strong adhesiveness and adhesive strength By adding petroleum resin, pine resin, modified phenolic resin as tackifier and adding back carbon and zinc oxide as reinforcing agent, maximizing hardness retention and cohesiveness of adhesive and manufacturing by adding kaolin and cray as filler Then it provides a manufacturing method to express a strong adhesive strength.

The dendritic elastic rubber (TPE) may be used alone or mixed with SBS (Styrene Butadiene Styrene) or SIS (Styrene Isoprene Styrene), which is a thermoplastic rubber. SBS has good elongation and SIS has good tensile strength, so it can be mixed and used to show excellent properties of both sides according to the request of the consumer.

The oil applied in the present invention may be petroleum mineral oil such as process oil, but the present inventors have tested the result of linseed oil or semi-dry oil which is a dry oil. The use of vegetable oil (Rape Seed Oil) showed strong toughness and strong adhesiveness and adhesion.

For reference, the manufacturing method of the waterproofing material of the polymer synthetic resin sheet using the method of manufacturing the adhesive agent, for the rubber stirrer (Kneader) or rubber by adding an oil (oil) and a tackifier to the rubber (Rubber) Apply the adhesive on top of the polymer synthetic resin (PP, PE, EVA, Urethane) film sheet while rolling the adhesive mixed with stirring in the Open Roller, or rolling it in a calendar or extruding it with T Die in an extruder. While there is a method of drawing and withdrawing, such a manufacturing method is difficult to produce due to the adhesive property of the adhesive and very soft fluidity, and has a disadvantage in manufacturing that production efficiency is extremely low, and on the top and bottom of the polymer synthetic resin sheet film At the same time, it cannot be produced while applying the adhesive agent.

Another method of preparing the adhesive may be a method of preparing a liquid adhesive by dissolving the rubber in an organic solvent in a liquid stirrer, but the liquid adhesive is 40 to 60% solids, odor of organic solvent and a large fire When a liquid adhesive with a small amount of liquid is applied to a polymer synthetic resin sheet film with a predetermined thickness, only the adhesive agent as a solid should be applied to the polymer synthetic resin film sheet by evaporating an organic solvent in the air. However, there is a risk of odor and fire in the evaporation process, and it can also be prepared by applying an adhesive to only one side of the polymer synthetic resin sheet. As described above, it is very difficult to manufacture a polymer synthetic resin sheet waterproofing material using the manufacturing method of the adhesive agent as described above, and there is a risk of large fire, and thus there is a limitation in manufacturing a polymer synthetic resin film sheet waterproofing agent. PE, EVA, PVC, urethane, etc.) After undergoing a lot of trial and error to study the manufacturing method of the adhesive for attaching the adhesive to the film sheet to provide a production method of the adhesive agent of the solvent-free type of the present invention. .

In order to prepare excellent adhesive agent, it is indispensable to manufacture various kinds of tackifiers and additives in rubber, and the stronger the adhesiveness and adhesiveness, the more difficult it is to manufacture in the rubber mixing machine, Laura and kender. When dissolved in organic solvents and prepared in liquid form, the organic solvent must be evaporated inevitably because of its low solids content. Therefore, viscous rubber remains. Therefore, organic solvents must be evaporated for this purpose. Odor and fire risk and inefficiency could not be adopted as a manufacturing method.

According to the manufacturing method of the present invention, it is a solvent-free adhesive preparation method of 97-99% of solid content prepared by dissolving dendritic elastic rubber in oil and adding additives such as a tackifier. It provides production and eco-friendly manufacturing method, and it is very simple and eco-friendly manufacturing method by applying adhesives on both sides of the upper and lower sides of the polymer synthetic resin film sheet in one manufacturing process. It is.

It is to provide a method for producing a breakthrough waterproofing agent that is differentiated from the conventional waterproofing material.

In addition, in the present invention, the conventional polymer synthetic resin (PP, PE, EVA, PVC, urethane) film sheet has improved the disadvantages that it is very difficult to bond the connection parts overlapping one end of the sheet and the sheet because there is no adhesiveness, According to the invention by coating the adhesive adhesive with the self-adhesive on the top and bottom of the polymer resin film sheet in the form of a sandwich-like integrally manufactured, the polymer synthetic resin sheet waterproofing agent of the present invention PP, PE, EVA, PVC Combining the strong tensile strength, tear strength, high elongation rate, excellent durability and water resistance of the film sheet itself made of polymer synthetic resin such as polyurethane and urethane, it has excellent physical properties, and sheet-to-sheet bonding has strong point and adhesion.

When the tackifier is stirred to dissolve completely, when the dendritic rubber and the tackifier are completely dissolved in oil, the heating of the heating liquid stirrer is interrupted and aluminum stearate (3 g) and barium stearate (1 g) are added. Then, the anti-aging agent PA (1.5g), DCD (1.5g), RD (1.3g) and the reinforcing agent, back carbon (15g), zinc oxide (5g) was added and stirred to mix evenly. Longitudinal the filler of kaolin (30g), it is the production of pressure-sensitive adhesive of the present invention to give the mixture was stirred and mixed uniformly dispersed by adding a cradle (10g).

Another preferred construction method for the waterproofing of the vertical wall, such as underground structures in the construction method for waterproofing of the present invention is a pre-treatment step of grounding the base surface of the vertical wall of the adherend in the same manner as above; Peeling off the silicone-treated release paper attached to the lower portion of the prepared polymer synthetic resin film sheet and attaching from the lower portion of the wall while attaching the end portions by 10 cm, attaching the waterproof sheet to the upper portion while extending the upper portion; Peel off the release paper attached to the upper part of the waterproofing film sheet of the polymer synthetic resin film sheet attached to the concrete wall and apply the water-kneaded mortar with 10 to 20mm thickness with the waterproofing layer protection agent or PP, PE with a thickness of 10-20mm , PS foam sheet, iso pink, PE hard plate, asphalt-based hard plate, one of the natural and synthetic fiber hard plate (waterproof layer protective material) is attached and then backfilled to complete the waterproof construction.

In another construction method for waterproofing of the present invention, a preferred construction method of the cross-linked top plate, the step of cleaning the bottom surface of the iron structure of the cross-section top plate cleanly; Peel off and release the release paper attached to the lower part of the waterproofing agent prepared by applying overlapping ends by 10cm, and peeling off the release paper attached to the upper part of the waterproofing agent attached to the cross-coated top plate and fixing the SBR latex modified concrete. In the step of attaching thickness (50 ~ 100㎜), the waterproof construction and the paving work of the bridge top plate are completed.

The point-adhesive waterproofing agent of the present invention is very strongly adhered to water and kneaded mortar or steel sheet. However, in the case of the iron plate may be attached directly to the waterproofing agent of the present invention, but if the surface is rusted, it is preferable to apply a waterproofing agent after applying a thin primer (Primer).

Referring to FIG. 8, in another construction method for waterproofing, a preferred waterproofing method for reverse casting of a floor of an underground structure, an upper part of a parking lot, or a wall of a structure may include a surface of an adherend to be waterproofed. Pretreatment step to remove background, remove irregularities, crack repair, water and oil, and clean up the ground, and apply adhesive on a 0.1-2mm thick polymer film sheet with a width of 100cm. The release paper is attached to the lower part of the waterproof sheet 10 prepared by attaching the release paper (3) in the state to be placed on the adherend, peeling only the release of the sheet and the connecting portion of the end of the sheet and overlap the sheet and the sheet by 10 cm Attaching and leaving the lower release paper intact; Remove the release paper on the upper side of the waterproof sheet on the base concrete (adhesive) and press on it to apply mortar, cast concrete, or attach a waterproof layer protection agent to complete the waterproof construction.

The reverse casting method is a construction method that is different from the normal waterproof construction method. The reason for the reverse casting method is that if the waterproof sheet is strongly attached to the base concrete which is the adherend, the repetitive contraction and relaxation action of the base concrete is applied. At some point, the crack breaks rapidly, as the concrete splits from 1mm to even 20-30mm, in which case the waterproof sheet strongly attached to the ground concrete is cracked to the same width, and the waterproof sheet may touch and crack and leak. have. In this case, it is a waterproof construction method that detaches and attaches the waterproof sheet to the base concrete without attaching the waterproof sheet, and attaches the waterproof sheet to the concrete on the opposite side, and does not attach concrete to the upper and lower portions of the polymer resin film sheet. Only one side of the sheet is attached to complete the construction.

In the above, the configuration and operation of the manufacturing method of the waterproofing agent according to the present invention and the construction method using the same are shown in accordance with the above description and the drawings, which are merely described as examples, and do not depart from the spirit of the present invention. Various changes and modifications are possible.
