Description

Painted and adhesively adhesive polymer waterproof sheet and its manufacturing method and waterproofing method using the same {Paintable and adhesable polymer multi-layered waterproof sheet and its manufacturing method and its waterproof construction method}

The present invention relates to a polymer multilayer composite sheet having paintability and adhesiveness and a waterproof construction method using the same, wherein the waterproof sheet has a polymer sheet constituting the top of the waterproof sheet in order to solve the difficulty of coating the paint on the top. By providing a functional group to the sheet) and having excellent adhesion to the coating film, it has a feature that can be applied to the thick film as a protective layer of the composite waterproof sheet.

The concept of waterproofing has emerged because of the degradation of watertightness and strength of concrete due to aging of concrete structures, as well as cracks caused by internal loads and external impacts. It is classified as waterproof and implemented in various ways.

As the construction technology of civil engineering and construction field has been developed day by day, complicated and difficult construction, which was difficult in the past, has been solved without difficulty, but waterproof construction often causes defects. If the waterproof construction is wrong, it may cause leakage and flooding to civil engineering and building structures, and cause corrosion and damage to the finished structure.

Therefore, in the field of civil engineering and construction, the importance of waterproof construction is highlighted, and the emergence of excellent waterproofing materials that can exert a perfect waterproof function continuously until the disassembly of civil engineering and buildings with a single simple waterproof construction is urgently required.

As the importance of waterproofing systems in civil engineering and construction has been evaluated according to the trend of the times, various waterproofing agents have been developed and used from the past to the present, but there are advantages and disadvantages according to each waterproofing agent. Discomfort is urgently demanding the emergence of more excellent waterproofing agents than advantages.

The waterproofing agent mainly used liquid asphalt waterproofing agent, and it has been gradually developed into coating waterproofing agent, bentonite waterproofing agent, and rubber sheet waterproofing agent according to the change of the times. Among the conventional waterproofing agent, rubber-based waterproofing agent has excellent strength and high elongation. It has been evaluated as a waterproofing agent having excellent physical properties and has been widely used in recent years, but its price is rather expensive.

Accordingly, although the waterproof member is thin, it manufactures and supplies a composite waterproof sheet having asphalt or the like attached to a polymer resin sheet having low price and excellent mechanical properties, but the sheet and the sheet are not easily connected. It is waterproofing by heat fusion method that melts and pastes the surface of the polymer synthetic resin film sheet by applying high heat, which is a heat fusion method, using a torch lamp, a burner or a hot air blower to the joint to be connected to the sheet.

This conventional waterproof construction has been using a method such as adding a waterproofing liquid in the process of aging concrete to waterproof, or finishing using a sheet or the like after lamination using the waterproofing liquid.

However, such a waterproof construction is not only exposed to the risk of fire, but also exposed to the danger of fire, the problem of deterioration of the waterproof effect due to the aging of the waterproof layer over time occurred.

Therefore, according to the waterproof construction, it is necessary to partially repair after about 1 to 2 years, and it is almost impossible to completely waterproof the leaked part even by such an effort.

In addition, the usual inorganic waterproof paints are mainly designed to waterproof the cement and sand and methyl cellulose mixed with water or a water-soluble adhesive.

In particular, water and sewage structures composed of concrete structures using such a method have no antimicrobial effect on water or sludge freshwater with existing inorganic water-based paints. There is a problem that toxin-rich substances are generated.

In addition, since the high temperature heat is applied by using a torch lamp or a heat blower to attach the joint between the polymer resin film sheet and the sheets, the sheets and the joints of the sheet may not be uniformly melt-bonded. If it is, it may cause the waterproof construction defect due to leakage.

In other words, the joints to which the polymer resin film sheet and one end of the sheet are attached are partially waterproofed in a state where holes are formed due to overheating of the torch lamp or the hot air or the polymer resin film sheet is not melted due to the low heat. If the waterproof construction is completed in a state where the seat is not completely connected to the sheet, the waterproof construction is completed by providing a leak and water damage is provided.

In order to solve the above problems, the strength is better than the existing waterproof layer, the impact resistance is excellent, it is strongly adhered to the concrete structure, and the joints between the waterproof sheets after the construction must be sealed to each other to exhibit a perfect waterproof function. Easily adhered to shorten the construction time. As a waterproof protective layer, in addition to mortar plastering, pressed concrete placing, and waterproofing protective agent, it is possible to directly paint the surface with thick film on various surfaces to realize various colors, durability and aesthetics. Finally, it must be able to withstand the erosion by acidic substances caused by bacteria, and must be waterproof, harmless to the human body as well as weather resistance, water resistance, weather resistance, abrasion resistance, chemical resistance.

In order to achieve the above object, in the present invention, a polyolefin resin or copolymer (modified with a reactive monomer such as maleic anhydride, acrylamide or alkyl acrylic acid) is used.

Here, the polyolefin is a typical non-polar polymer, and there is no functional group in the molecular chain, so in order to chemically modify it, radicals must be generated in the polyolefin to perform a chemical reaction.

The method of generating radicals includes a method of adding a peroxide, an electron beam or gamma irradiation method, or a shear force method.

Thus, in order to give polarity to polyethylene after forming radicals, a reactive monomer such as maleic anhydride, acriamide or alkylacrylic acid is added to induce a grafting reaction or copolymerization to form a copolymer.

Since polyolefin is a representative nonpolar material, it has no affinity with most materials and thus has very low adhesive properties.

(Table 2) Changes in physical properties due to the addition of minerals

As described above, the polymer multi-layer composite waterproof sheet applied to the uppermost polyolefin resin or copolymer resin modified with a reactive monomer has excellent affinity with paints based on epoxy, urethane, and acrylic copolymer resins.

The linear low density polyethylene constituting the polymer multi-layer composite waterproof sheet refers to a low density polyethylene made by a high pressure method of polymerizing ethylene gas generated at high pressure by the decomposition of waste gas or naphtha of a refinery at high pressure. Soft and melting point is about 107 ~ 112 ℃, specific gravity is 0.92, transparency is high, and it is a kind of low density polyethylene made using metallocene elite dome metallocene catalyst, so it has excellent water resistance, chemical resistance, electrical insulation, and ductility. Subsequently, the strength was weak, but it was used in the composite sheet by using the modified polyolefin resin or copolymerized resin to complement each other's physical properties.

Here, the release paper 30 made of the release film may be attached only to the surface on which the adhesive layer 20 is applied, and the opposite side may also attach the release paper 30 made of the release film to protect the waterproof surface. Do.

Here, the release paper 30 may be made of a paper material instead of a film.

The adhesive layer 20 is formed on the bottom of the composite coating waterproof sheet 10 while having two properties of adhesiveness that can be re-adhesive and adhesive which is not re-adhesive after curing, but the adhesive layer of the present invention 20 is very strongly adhered to the water and kneaded mortar or iron plate, so that the adhesive layer 20 may be formed on both sides of the composite coating waterproof sheet 10 in order to completely protect the composite sheet layer. .

The adhesive layer 20 is composed of a rubber topic that plays a role of giving elasticity and strength, a filler for reinforcing physical properties, a pigment to give color, a plasticizer to control hardness, and a tackifier to impart tackiness.

The rubber agent is composed of butyl rubber, ethylene propylene diene rubber, styrene-isoprene-styrene rubber, styrene-ethylene-butadiene-styrene rubber or styrene-butadiene-styrene rubber.

The filler is used quicklime, calcium hydroxide, calcium carbonate.

The pigment uses fat sugar, silicon dioxide or iron oxide.

The plasticizer may be dioctyl phthalate, diisononyl phthalate, dioctyl adipate, dibutyl phthalate or citrin acid ester.

The tackifier may be a Kumaron-indene resin, a terpene-phenol resin, a polybutene resin or a hydrogenated rosin ester resin.

The weight ratio of the adhesive layer 20 is 5 to 25 parts by weight of rubber, 5 to 25 parts by weight of filler, 2 to 15 parts by weight of pigment, 15 to 30 parts by weight of plasticizer, and 30 to 50 parts by weight of tackifier.

In the method for preparing the adhesive layer 20, a rubber and a tackifier are put in a kneader for producing a hot-melt, firstly mixed with a stirrer at 150 to 180 ° C, and the filler, the plasticizer, and the pigment are used. After further adding and remixing with a stirrer at 100 ~ 120 ℃ to complete the formulation of the adhesive.

The polymer multi-layer composite waterproof sheet is manufactured in the polymer multi-layer composite waterproof sheet manufacturing step of bonding the release paper 30 in the release paper bonding step through the manufacturing step of the composite coating waterproof sheet, adhesive bonding step, adhesive bonding layer forming step. do.

The primer layer forming step is to remove the latent surface, irregularities, cracks, moisture, water and oil, etc. on the surface of the complex and to form a primer layer by applying a thin primer with a spray or brush or paint roller on the surface of the complex.

The reason for forming the primer layer is that if you attach the waterproof sheet paper directly on the concrete slab, but it does not stick well, and after applying the waterproof sheet on it, it is closely adhered and maintained for a long time. The primer is an oil-based liquid of asphalt series, and has adhesive force. It also adheres well to concrete, so it can be used as a base material before attaching the waterproof sheet, and has the additional effect of preventing the penetration of moisture into the concrete before the waterproof sheet process. Application of a coating amount of about 100 to 500 g / m ² is most desirable and low temperature However, when the viscosity is too high, 10 ~ 30% of thinner can be diluted.

The curing step is 3 to 4 hours in the summer after the primer is applied, 4 to 8 hours in the winter to put a curing time to check and complement the abnormality of the base surface after primer coating.

The step of attaching the waterproof sheet removes the release paper 30 attached to the polymer multi-layer composite waterproof sheet and attaches it to the base concrete so that one end is overlapped by 8 to 10 cm by attaching the waterproof sheet and then applying pressure with a roller or the like. Fully glued.

The method of extending the polymer multilayer composite waterproof sheet is a method of overlapping and installing the waterproof sheet, and expands while attaching the end portion to be evenly engaged while attaching the waterproof sheet, and then flatten the waterproof sheet cut to a width of 8 to 10 cm. The waterproof sheet may be extended by attaching to an upper portion of the connection portion of the waterproof sheet that is engaged.

Since the adhesive layer 20 is very strongly adhered to water and kneaded mortar or iron plate, the adhesive layer 20 on both sides of the composite coating waterproof sheet 10 in order to completely protect the composite coating waterproof sheet layer ) May be formed.

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 the composite sheet after applying a thin rust preventive primer.

The protective layer forming step may be performed by attaching the composite sheet to a skin deposit layer such as rooftop slab concrete, finishing with mortar plastering or placing pressed concrete or attaching a waterproof layer protective agent to protect the composite sheet. The composite sheet can be protected, but according to a more preferred feature according to the present invention, since the coating sheet having an affinity with the coating resin is at the top, it is finished with a coating based on epoxy, urethane or acrylic copolymer resin having excellent coating properties. Various colors can be realized, durability is improved, and waterproof effect can be further increased.

As described above, the present invention can be widely applied to industrial structures, civil works, buildings, bridge decks, and the like, and thus, industrial use value is great.
