Waterproofing lining work is usually carried out on the surface of civil engineering and construction structures including water tanks, water reservoirs, water purification plants, salt tanks, chemical plants, waste treatment plants, gas stations, car washes and tunnels to ensure the durability of the structures. In particular, structures such as water tanks, water intake, water purification, drainage, and salt tanks are equipped with concrete tanks or steel frame tanks to drain large amounts of water. Inside the tanks, waterproof lining works to secure the durability of the tanks, Prevent contamination of fresh water.

The waterproof lining construction is generally a wet method of applying epoxy resin or glass fiber reinforced thermosetting resin. However, the wet method has a disadvantage that it is not only troublesome to work on the field but also a harmful working environment and it is difficult to ensure a uniform waterproof quality. Recently, a drying method in which a waterproof sheet of stainless steel or polyethylene type is installed and proposed has been proposed and applied.

However, in the case of using stainless steel in the conventional dry method, not only the installation cost is high but also the water is likely to be contaminated or the strength of the stainless steel is lowered due to the water reacted to the water tank in the weld portion of the stainless steel. As shown in FIG. 1, when the polyethylene-based waterproof sheet is used, since the waterproof sheet is made to have a thickness of about 3 mm, there is a great fear that the waterproof sheet is easily lifted from the overlapping joint. Further, There was a problem.

In order to overcome the disadvantages of the conventional dry method as described above, a polypropylene-based waterproof lining roll sheet has been developed and patented as Patent No. 10-1142123. The present invention has developed the present invention as a PP roll antimicrobial waterproof sheet for waterproof lining which can further improve antibacterial property and economic efficiency by further developing Patent No. 10-1142123.

The present invention relates to a waterproof lining sheet which is developed to improve the disadvantages of the conventional waterproof lining technology and which can be carried out by a dry method and can be economically produced while being advantageous in preventing contamination of water dewatered in a water tank There is a technical problem to provide a PP roll antimicrobial waterproof sheet for a new waterproof lining, a preferable production method of the antimicrobial waterproof sheet, and a waterproof lining method which preferably uses the antimicrobial waterproof sheet.

In order to solve the above technical problems, the present invention provides a roll sheet type waterproof sheet comprising a first composition comprising 30 to 70% by weight of a polymer resin by PE, EPDM, EVA or PP and 30 to 70% by weight of a filler A waterproof bottom sheet; And an antimicrobial waterproof top sheet made of a second composition comprising 20 to 60% by weight of a PP resin, 10 to 70% by weight of a thermoplastic elastomer resin and 2.5 to 30% by weight of an antimicrobial agent, Wherein the PP roll for waterproofing lining is provided with an antimicrobial waterproof sheet. The second composition may further contain 0.5 to 6% by weight of a self-limiting agent or 1 to 10% by weight of a pigment.

The present invention also relates to a method for producing a PP roll antimicrobial waterproof sheet for waterproof lining, which comprises extruding a first composition to produce a waterproof bottom sheet having a thickness of 0.7 to 3.0 mm and extruding a second composition, A first step of producing a waterproof top sheet; And a second step of winding the waterproof bottom sheet and the top sheet of the antimicrobial waterproofing sheet by a thermal fusion welding process and cooling them.

Further, the present invention is characterized in that a primer is applied to a waterproof base surface of various civil engineering and building structures including a water tank, a water tank, a reservoir, a water purification plant, a salt water treatment plant, a chemical plant, a waste treatment plant, a gas station, A waterproof lining method characterized by attaching a roll antimicrobial waterproof sheet is provided.

According to the present invention, the following effects can be expected.

First, since the present invention has a double-layer laminated structure of a waterproof bottom sheet and an antimicrobial waterproof top sheet with antibacterial performance, economical efficiency can be ensured by adding antimicrobial performance to only the upper part while ensuring waterproof performance as a whole. Particularly, the lower sheet which is not exposed to the outside can use the recycled resin, which is more advantageous in securing economy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings and preferred embodiments.

2 is a sectional view of a PP roll antimicrobial waterproof sheet for a waterproof lining according to the present invention. The PP roll antimicrobial waterproof sheet for a waterproof lining according to the present invention is a waterproof sheet made of a roll sheet type and made of a laminated structure of a waterproof bottom sheet 10 and an antimicrobial waterproof top sheet 20 as shown in FIG. . The surface facing directly to the waterproof space is treated with a high performance antimicrobial waterproofing top sheet 20 having both waterproof and antimicrobial properties while the surface attached to the structure is treated with an economical waterproof bottom sheet 10 having only waterproof performance It is. As a result, waterproof performance and antibacterial performance as well as economy can be ensured at the same time.

Furthermore, the PP roll antimicrobial waterproof sheet for waterproof lining according to the present invention comprises an intermediate fleece fabric 30 sandwiched between a waterproof bottom sheet 10 and an antimicrobial waterproof top sheet 20 as shown in FIG. 2 (b); A lower fleece fabric 40 joined to the lower portion of the waterproof lower sheet 10; A release film (50) attached to the top of the antimicrobial waterproofing top sheet (20); As shown in FIG. The intermediate fibril 30 and the lower fibril 40 serve to compensate the tensile performance and elongation of the waterproof top sheet 20 and the waterproof top sheet 20, and one of the nonwoven mesh 1 to 7 is suitable. In particular, if the nonwoven fabric laminated with the nonwoven fabric is made of acrylic resin and the fibrillated fibers 30 and 40 are joined to the waterproofing lower sheet 10 to the antimicrobial waterproofing upper sheet 20, the waterproofing lower sheet 10, (Structure) of the lower sheet 10 and the adhesive strength to the base surface (structure) of the waterproof sheet. The release film 50 protects the antimicrobial waterproofing top sheet 20 to prevent damage due to external impact or stimulation during transportation and storage. The fibrils 30 and 40 may be appropriately selected from natural fibers, polyester, polyethylene terephthalate, and polypropylene, and the release film 50 may be selected from polyethylene, polypropylene, polyvinyl chloride, cellulose acetate and the like.

In the present invention, the waterproof bottom sheet 10 is a sheet made of a first composition containing 30 to 70% by weight of a polymer resin by PE, EPDM, EVA or PP and 30 to 70% by weight of a filler. It is made of PE, EPDM, EVA or PP with a polymer resin to ensure waterproof performance while weighing with a filler to produce a sheet with stable smoothness. Since ordinary PE, EPDM, EVA or PP is light in weight, it can be stabilized smoothly by using appropriate weight of filler. The filler is calcium carbonate. On the other hand, since the waterproof bottom sheet 10 is not directly exposed to the waterproof space and is not exposed to the outside, it is possible to further secure economical efficiency by using a low-quality polymer resin if it has only basic waterproof performance. For example, PE, EPDM, EVA Or PP as recycled resin. The content of the polymer resin and the filler in the waterproofing lower sheet 10 is a result of simultaneously considering the waterproof performance, the smoothness of the sheet, the moldability, and the economy.

The antimicrobial waterproofing top sheet 20 is a sheet made of a second composition comprising 20 to 60% by weight of a PP resin, 10 to 70% by weight of a thermoplastic elastomer resin, and 2.5 to 30% by weight of an antimicrobial agent. The antimicrobial waterproofing top sheet 20 is directly exposed to the waterproof space and exposed to the outside, so it is important to secure a certain quality. Taking this into consideration, the PP resin is used as a base material to ensure basic waterproof performance, heat resistance, chemical resistance, ozone resistance, Is made of a thermoplastic elastomer resin to soften the hard PP while improving the tensile strength and ensuring the antibacterial performance with the antibacterial material. In fact, as a result of producing the sheet with the second composition in the above-mentioned range, it is possible to obtain a sheet having excellent waterproof performance as well as basic chemical resistance (hydrochloric acid, hypochlorous acid, sulfuric acid, sodium hydroxide), weather resistance, ozone resistance Fatigue resistance and the like.

The PP resin in the antimicrobial waterproofing top sheet 20 is preferably selected from among a propylene homopolymer, an alpha-olefin-propylene copolymer having 4 to 20 carbon atoms, and an ethylene-propylene copolymer having an ethylene content of 0.5 to 15 weight% And more preferably selected from a propylene homopolymer and an ethylene-propylene copolymer. In particular, the ethylene-propylene copolymer preferably contains ethylene in an amount of 0.5 to 15% by weight or more. When the propylene content is less than 85% by weight and the ethylene content is more than 15% by weight, fish eyes or orange peel Peel), and when the propylene content exceeds 99.5 wt% and the ethylene content is less than 0.5 wt%, the impact strength is lowered. In addition, it is preferable that the PP resin has a melt mass flow rate (ASTM D1238) of 1 to 5 g / 10 min (230 ° C, 2.16 kg load). When the PP resin has such a melt mass flow, The moldability of the thickness can be effectively provided. If the amount of the PP resin is less than 20% by weight, it is difficult to expect the mechanical properties of the PP resin. As a result, the mechanical properties such as the impact strength of the resin composition as a whole may be reduced and the molded article may be easily deformed. %, The ductility is lowered and it is difficult to form the film into a thin thickness.

The thermoplastic elastomer resin softens the PP resin to provide ductility and improve tensile strength. The thermoplastic elastomer resin is suitably selected from among a styrene elastomer, an olefin elastomer, a urethane elastomer, an amide elastomer, a butadiene elastomer, an ether elastomer, an ester elastomer and a silicone elastomer, more preferably styrene / butadiene Styrene / ethylene / butylene block copolymer, styrene / ethylene / butylene block copolymer, styrene block copolymer, styrene / isoprene block copolymer, styrene / butadiene / styrene block copolymer, styrene / isoprene / styrene block copolymer, / Styrene (SEBS) block copolymer, a styrene / ethylene / propylene block copolymer and the like, a polyester type polyurethane thermoplastic elastomer, a polyether type polyurethane thermoplastic elastomer , And an ethylene copolymer is selected from a thermoplastic elastomer. Such elastomeric products include Hytrel from Dupont, Pelprene from Toyobo, Skypel from SKI, UBE-PAE from UBE, JSR SB from Japan Synthetic Rubber, Shell Kraton Q, Japan Synthetic Rubber Company RB, Dexter Dexflex, Honam Histomer, Sumitomo Sumitomo TPE, Dow Versify 2300, and ExxonMobil's Vistmaxx. The thermoplastic elastomer resin is selected to have a melt mass flow (MFR, ASTM D1238) of 1 to 20 g / 10 min (230 ° C./2.16 kg), preferably 1 to 10 g / 10 min, It is possible to effectively provide moldability with a thin thickness while being fused with the polypropylene resin. On the other hand, the thermoplastic elastomer resin is used in an amount of from 10 to 70% by weight. If it is less than 10% by weight, it is difficult to soften the PP resin and improve the tensile strength. If it exceeds 70% by weight, .

The antimicrobial agent may be a conventional antimicrobial agent incorporated into the polymer resin as it is, but more preferably, an antimicrobial agent according to Patent No. 10-0536551 is used. That is, an antimicrobial monomer compound represented by the following formula (1), an antimicrobial homopolymer compound having the following formula (1), an antimicrobial copolymer compound having the following formula (1), and an acrylic copolymer having the following formula Lt; RTI ID = 0.0 > antimicrobial < / RTI > These antimicrobial compounds have a continuous antibacterial activity and a high heat resistance, and when added to a conventional resin, the antimicrobial compound does not elute and does not cause toxicity and does not affect the physical properties of the molded product.
