Description

Functional waterproof mortar for inner and outerwall of building

The present invention relates to a functional waterproof mortar used for finishing or repairing building walls. More specifically, the present invention includes water, cement, silica sand, acrylic copolymer resin, silica airgel, polyether ether ketone copolymer resin, dispersant and antifoaming agent, heat insulation, water resistance, heat resistance, flame resistance, flame resistance It is a field of functional waterproof mortar for interior and exterior walls of buildings with improved physical properties such as chemical and weather resistance.

Conventional wall construction method after the construction of a wall, such as concrete, post-installation finishing materials such as waste int or wood, or after the functional member having a thermal insulation such as styrofoam, glass fiber or sheet to the concrete wall, After finishing the finishing materials such as mortar, the walls were imparted with functionality such as heat insulation, water resistance, heat resistance, flame retardancy, chemical resistance and weather resistance.

Also, due to the development of chemical engineering, paint compositions are gradually being replaced by environmentally friendly materials. Water-based paint applied to the interior wall of a building's living space is used to simply form a coating on the cement wall to give an aesthetic effect. In recent years, water-soluble paints with functions such as heat insulation, waterproofing, heat resistance, flame retardancy, chemical resistance and weather resistance in addition to the basic performance are required in consideration of the improvement of the quality of life and stability of the living culture and health.

Korean Patent Publication No. 10-0610457 discloses an aqueous coating composition having excellent fouling resistance and elasticity, and Korean Patent Publication No. 1999-014598 discloses a water coating composition for crack-following building insulation. have. However, these paints do not have excellent waterproof performance, and do not send outstanding performance in durability.

In addition, various permeable coating waterproofing agents are currently commercially available, but many problems are exposed in the effect and durability. That is, the permeable coating waterproofing agents such as polystyrene, polyvinyl chloride and aqueous solution vinyl chloride, and vinylidene chloride emulsion, which are mainly used, bring unnatural luster to the building when applied to the exterior walls or roofs of buildings. The effect is to easily age, shorten the life and easily weather and lose its performance.

On the other hand, since oil-based paints used a large amount of aromatic solvents such as benzene, toluene, and xylene, it contains VOCs and harmful toxic components such as lead, heavy metals, benzene, toluene, and xylene, which are harmful to the human body. Not only does it violate environmental regulations, but it also causes swelling or discoloration of the painted walls. For example, the silicone resin solvent-type permeable coating waterproofing agent Aqua Seal (trade name) manufactured by Nippon Steel Chemical Co., Ltd. and Liquid Plastic (trade name) manufactured by Elp and I. Co., Ltd., are swelling and discoloration of the wall when sprayed on the paint wall due to the use of petroleum solvents. Bring. The emulsion-type permeable coating waterproofing agent based on paraffin wax is cheap, but it is known that whitening and yellowing occur due to the effect of emulsifier and its wear resistance is not long lasting.

In addition, aqueous paints contain ammonia and formalin, and in the field workability, the adhesion of the paint composition is weak, so that the stock solution flows down before infiltrating and drying into the mother body, and thus physical properties such as heat insulation, water resistance, heat resistance, flame resistance, chemical resistance and weather resistance There is a disadvantage that there are many functional weaknesses in the lifespan protection and repair application of buildings due to the lack of improvement.

In addition, the fluorine-based paint has excellent performance in many ways, but has a disadvantage that the price is much higher than other products.

Recently, as the quality of life is improved, the importance of stability and health of the living culture is important, and therefore, a technology that can solve indoor air pollution by volatile organic compounds (VOC) that is harmful to the human body is needed. Conventional waterproofing agents are designed and produced with oil-based paints to satisfy basic performance, but lack of environmentally friendly performance due to insufficient or lacking regulations on volatile organic compounds (VOC) causing sick house syndrome.

The most commonly used concrete floor surface finishing materials are epoxy resins, urethane resins, vinyl resin-like finishes, and the epoxy and urethane resins have excellent flexibility, elasticity, dustproofness, and stain resistance. Not only is it excellent in workability and quick-drying property, but also has excellent initial adhesive strength, excellent water resistance, and a large amount of various fillers.

However, epoxy and urethane-based floorings are mostly products containing volatile organic compounds, which may cause fatal adverse effects on the human body such as worker's working environment risk during construction and long-term risk exposure of the builder and user due to continuous volatilization of residual solvent after construction. In addition, there is a problem of a fire that can cause a large accident due to the generation of toxic solvents and high vulnerable to fire and highly vulnerable to fire after construction, and a large amount of toxic gas during the fire.

In particular, epoxy-based floorings generate a large amount of bisphenol A and volatile environmentally harmful compounds (VOCs 44mg / kg) and contain a large amount of lead (70mg / kg), which is a heavy metal. In particular, it is fatal to pregnant women), and the level of environmentally harmful compounds (VOCs) is 11 times higher than the standard value (4mg / kg), and these components emit toxic gases at the time of fire, causing many casualties. The use of such organic flooring is regulated.

In addition, the epoxy and urethane-based flooring is excellent in surface water resistance, but weak to water pressure and possibly peelable, there is a problem in long-term adhesive strength due to the difference in moisture content and stretch rate with concrete, artificial color and design is simple and weak to UV and moisture for external use Not only is there a problem, but there is a problem that the construction must be performed at 5 degrees or more.

In other words, the epoxy, urethane-based flooring material is inorganic cement as the time elapses because it is insufficient resistance to the concrete surface behavior, and simply adhered to the concrete floor surface by the adhesive properties of the flooring material itself as shown in the following figure It breaks, peels and falls off from the bottom surface, and it has poor adaptability to heat changes, so in places where high temperature and water are used, the construction site is lifted due to the evaporation pressure of water, and flammable materials are used. As a result, the risk of spreading the flash point at the time of fire not only exists, but also is not breathable, thereby accelerating secondary degradation due to the difference in elastic modulus.

As a material for solving the environmental and physical problems of the epoxy and urethane flooring materials and preventing dust generation such as parking lot floors, cement-based color hardeners are added to which pigments are added to add color to cement components and some additives are added. In addition, it is inexpensive and has the advantage of shortening the air by batch construction, but it has no surface smoothness, easy to penetrate moisture, and after a certain period of time after application, pigment dusting and color change (decoloration) and There is a problem that whitening occurs, and continuous research and development is required to solve this problem.

The present invention has been made to improve the problems according to the prior art of the waterproof mortar used in the finishing construction of the building wall, the conventional waterproof mortar includes a volatile organic compound (VOC) harmful to the human body, or heat insulation, waterproof, heat resistance The main purpose is to provide a solution to the problem, which is insufficient in the properties such as flame retardancy, chemical resistance and weather resistance.

The present invention is to realize the desired object as described above,

The functional waterproof mortar for building interior and exterior walls according to the present invention as described above provides a functional waterproof mortar that is harmless to the human body, and the interior and exterior walls of buildings with improved physical properties such as heat insulation, waterproof, heat resistance, flame resistance, chemical resistance, and weather resistance. The effect that can provide a functional waterproof mortar for a dragon can be obtained.

The present invention is a waterproof mortar used in finishing or repairing a building wall, and is applied to the surface of a grounded building, and has a function of insulation, waterproof, elasticity, heat resistance, flame retardancy, chemical resistance, and weather resistance. It relates to a functional waterproof mortar for.

Functional waterproof mortar for building interior and exterior walls according to the present invention is 60 to 85 parts by weight of cement, based on 100 parts by weight of water; 70-90 parts by weight of silica sand; 3 to 10 parts by weight of acrylic copolymer resin; 0.5 to 3 parts by weight of silica airgel; 1 to 10 parts by weight of a polyether ether ketone copolymer resin; 0.5 to 3 parts by weight of a dispersant; Antifoaming agent 0.3 ~ 1 part by weight; is configured to include.

Specifically, the cement may be a general portland cement made of lime (CaO), silica (SiO 2), alumina (Al 2 O 3), iron oxide (Fe 2 O 3), and the like, and microcement having a smaller particle size than a general cement may be used. Among the above components, an alumina cement further containing an alumina component may be used. In this case, when using alumina cement, it may be used to include a predetermined amount of gypsum for the strength correction according to the expansion of the alumina cement.

At this time, the cement is preferably included in the composition ratio of 60 to 85 parts by weight with respect to 100 parts by weight of water contained in the present invention, if the cement is contained in less than 60 parts by weight of cement composition ratio is small, the adhesion to the surface of the wall There is a problem that the lowering of the waterproof mortar according to the present invention is difficult to stably adhere to the surface of the wall, and when it exceeds 85 parts by weight, the adhesive strength and strength are excellent, but the economical problem is inferior. desirable.

In addition, the silica sand is mixed with cement in the waterproof mortar according to the present invention to reduce the dry shrinkage of the cement during curing of the cement, to improve the compressive strength, and to prevent cracking of the waterproof mortar, the average particle size The larger the effect is to reduce the dry shrinkage and to improve the compressive strength, but in the present invention, it is preferable to use within 0.1 ~ 0.5mm in order to reduce the foreign matter to the waterproof mortar, and to maintain a smooth surface.

At this time, it is preferable that silica sand is contained in the composition ratio of 70-90 weight part with respect to 100 weight part of water contained in this invention. That is, when the composition ratio of silica sand is less than 70 parts by weight, the expectation for the effect of lowering the dry shrinkage of the cement by silica sand, improving the compressive strength, preventing the cracking of the waterproof mortar, and the like is insignificant, and exceeds 90 parts by weight. In this case, it is preferable to have a composition ratio within the above range because a problem may occur that the adhesion of the waterproof mortar may be impaired.

In addition, the acrylic copolymer resin is configured to increase the adhesion of the waterproof mortar with cement and waterproof mortar for wall finishing according to the present invention has a predetermined elastic force.

In other words, if the adhesive strength to the surface of the wall is provided only with cement, the elastic force of the hardened waterproof mortar applied to the surface of the wall is insufficient, and cracks may occur in the waterproof mortar due to shrinkage of the waterproof mortar or vibration of the building. Copolymer resin provides a predetermined elastic force to the waterproof mortar, and realizes the effect of providing the waterproof mortar through the properties of the polymer resin, and the adhesive force to the intermediate paint or middle panel, which is generally prepared with an acrylic copolymer resin It can exert the effect which can be increased as the same composition.

In the present invention, it is preferable to use an aqueous acrylic copolymer resin or a silicone-modified acrylic copolymer emulsion resin obtained by copolymerizing a silane compound having an ethylenically unsaturated group, an alkoxy or a hydroxyl group.

In addition, when the acrylic copolymer resin is included in the waterproof mortar for wall finishing in less than 3 parts by weight with respect to 100 parts by weight of water, not only the elastic force of the waterproof mortar by the acrylic copolymer resin is insufficient, but also Since the adhesion to the surface is inferior, it is preferable to be included in 3 parts by weight or more, and when included in excess of 10 parts by weight, the viscosity of the waterproof mortar rises, resulting in a problem of lowering workability. It is preferably included in the waterproof mortar for wall finishing at ~ 10 parts by weight.

In addition, aerogel is a super-porous material manufactured by allowing the gel to maintain the nano-pore structure by drying the wet gel synthesized by the sol-gel reaction without shrinkage by supercritical conditions or other methods in which no gas-liquid interface exists. It has excellent heat insulating properties. In addition, the present invention can impart the heat insulating property of the silica airgel to the waterproof mortar according to the present invention by including the silica airgel in which the airgelized silica airgel is included in the waterproof mortar.

In connection with the above, silica aerogels are all available by the various methods available, it is preferably included in the waterproof mortar for wall finishing at a composition ratio of 0.5 to 3 parts by weight with respect to 100 parts by weight of water. At this time, when the silica airgel is included in the waterproof mortar for wall finishing in less than 0.5 parts by weight in the waterproofing mortar for wall finishing, there is a problem that the thermal insulation by the waterproof mortar for wall finishing is insignificant, and when included in excess of 3 parts by weight Since the heat insulation is excellent, but the problem that the adhesion of the waterproof mortar for wall finishing work is impaired, it is preferable to have a composition ratio in the above range.

구조가 반복 구성되는 선형 방향족 폴리머 또는 상기 구조를 기본 구조체로 하는 공중합체 수지로서, 용융점이 대략 343℃를 갖아, 본 발명에 의한 벽체 마감시공용 방수 몰탈이 화재에 잘 견딜 수 있는 내열성을 갖을 수 있도록 하는 효과를 발휘한다.In addition, the polyether ether ketone copolymer resin

It is effective to make it work.

That is, when the waterproof mortar for wall finishing includes an organic composition such as an acrylic copolymer resin, the heat resistance may be inferior due to the organic composition vulnerable to heat, but the polyether ether ketone according to the present invention ) Copolymer resin exhibits the effect of solving the above problems.

In connection with the above, the polyether ether ketone copolymer resin is excellent in flame retardancy because the melting point is higher than the general synthetic resin as described above, so that the waterproof mortar for wall finishing according to the present invention does not further include a separate flame retardant material It exhibits the effect which can improve the chemical resistance of the waterproof mortar for wall finishing due to the characteristic of an aromatic polymer.

In addition, the polyether ether ketone copolymer resin is preferably included in the waterproof mortar for wall finishing at a composition ratio of 1 to 10 parts by weight based on 100 parts by weight of water. At this time, when the polyether ether ketone copolymer resin is included in less than 1 part by weight, the composition ratio is insignificant, and the improvement of physical properties such as heat resistance, flame retardancy, and chemical resistance of the waterproof mortar for wall finishing by the polyether ether ketone copolymer resin is somewhat insufficient. There is a problem of deterioration, and when included in excess of 10 parts by weight, it is preferable to have a composition ratio in the above range because the problem of the adhesion of the waterproof mortar for wall finishing by the acrylic copolymer resin occurs.

In addition, the polyether ether ketone copolymer resin included in the waterproof mortar for wall finishing of the present invention may be used in a liquid state or a solid state (powder state). At this time, the polyether ether ketone copolymer resin in the solid state is preferably used having a mean particle size of 100 ~ 600nm in order to induce smooth mixing with other compositions contained in the waterproof mortar for wall finishing.

At this time, when the average particle size of the polyether ether ketone copolymer resin is less than 100 nm, the particle size of the polyether ether ketone copolymer resin is too small to easily disperse the solvent water, the main adhesive composition cement and the acrylic copolymer resin. If the average particle size exceeds 600 nm, the particle size is so large that foreign matter on other compositions of the waterproof mortar for wall finishing occurs, and at the same time, the wall of waterproof mortar for finished wall finishing is produced. It is preferable to use one having an average particle size within the above range because a problem arises in that the coating on the substrate is not easy.

In addition, the present invention may be configured to further include 0.5 to 5 parts by weight of polyfluoroethylene-based copolymer resin with respect to 100 parts by weight of water-resistant mortar for wall finishing construction of the above configuration.

Specifically, the polyfluorinated ethylene-based copolymer resin is a copolymer resin generally comprising a composition known as 'teflon', and has excellent heat resistance that can withstand a long time even at a high temperature of about 260 ° C. or higher, and is flame retardant that is not easily burned. Excellent and excellent in chemical bonds and has excellent chemical resistance to contaminants having acidic or basic properties, thus exhibiting the effect of imparting the above properties to the waterproof mortar for wall finishing according to the present invention. do.

In this case, the polyfluorinated ethylene copolymer resin included in the waterproof mortar for wall finishing can be used in the liquid state or solid state (powder state), and in the case of using the solid state, the polyether ether ketone copolymer resin Preference is given to using those having an average particle size within the same range as the average particle size of.

Moreover, it is preferable to comprise polyfluoroethylene copolymer resin so that it may have a composition ratio in 0.5-5 weight part with respect to 100 weight part of water contained in the waterproof mortar for wall finishing. At this time, when the polyfluorinated ethylene copolymer resin is included in less than 0.5 parts by weight, the composition ratio is insignificant, and the improvement of physical properties such as heat resistance, flame retardancy, and chemical resistance of the waterproof mortar for wall finishing by the polyfluorinated ethylene copolymer resin is somewhat insufficient. There is a problem of deterioration, and when included in excess of 5 parts by weight, the physical property improvement by the polyfluorinated ethylene copolymer resin is more excellent, but the economical efficiency is lowered, the adhesion of the waterproof mortar for wall finishing by cement and acrylic copolymer resin Since this fall problem occurs, it is preferable to have a composition ratio in the above range.

In connection with the above, the waterproofing mortar for wall finishing according to the present invention includes the polyether ether ketone copolymer resin (if the polyfluorinated ethylene copolymer resin is further included, the polyfluorinated ethylene copolymer resin.) It is desirable to include a certain dispersant so that it can be uniformly dispersed in other compositions of the waterproof mortar for wall finishing.

At this time, the dispersant is included in the composition ratio of 0.5 to 3 parts by weight with respect to 100 parts by weight of water, if the dispersant is contained in less than 0.5 parts by weight of polyether ether ketone copolymer for other compositions of waterproof mortar for wall finishing Dispersion of resin may be insignificant, and when it exceeds 3 weight part, there exists a possibility that the adhesive force of acrylic copolymer resin may be impaired, It is preferable to maintain the composition ratio within the said range.

In addition, the dispersant may use an organic dispersant which is generally used, but the present invention is 2-2-2-methoxyethoxy ethoxy acetic acid, 5-methoxy pentyloxy 5-Methoxy pentyloxy acetic acid, 3,6,9-trioxadecanoic acid (3,6,9-Trioxadecane acid), palmitic acid, stearic acid, benzoic acid acid, propionic acid, sodium polyacrylate, ammonium polyacrylate, cetyltrimethyl ammonium bromide (CTAB), polyacrylic sodium salt, dode It is preferable to use a dispersant of any one or more of dodecyl benzene sulfonate or sodium dodecyl sulfate (SDS).

Dispersants of this kind include polyetheretherketone copolymer resins (which include polyfluorinated ethylene copolymer resins when the polyfluorinated ethylene copolymer resins are further included) and carboxylic acids (R-COOH; carboxylic acid, carboxylate (R-COO-; carboxylate), alcohol (R-OH; alcohol), glycol (R- (OH) 2; glycol), ammonium salt (R-NH3 +; ammoniate), sodium salt (R- Alkyl (-R) or alkoxy (-OR) containing a functional group of any one of Na +; sodium salt), sulfonate (R-SO3-; sulfonate) or sulfate (SO42-; sulfate); ) Surfactant composed of carbon chain.

The dispersing agent of the present invention having the above structure has affinity with the polyetheretherketone copolymer resin so that the polyetheretherketone copolymer resin can be adsorbed on the surface of the dispersant to effectively disperse in the solvent water, and the poly The general dispersant is that the ether ether ketone copolymer resin has a form in which a carbon compound such as alkyl (-R) or alkoxy (-OR) in the form of a chain is formed so that the molecular structure itself generated by adsorption is stable in a solvent. Compared with the dispersibility and stability is excellent.

In addition, the antifoaming agent is a structure for removing bubbles that may be generated while the cement and acrylic copolymer resin contained in the waterproof mortar for wall finishing according to the present invention, it is possible to use a general antifoaming agent corresponding to a water-soluble surfactant.

At this time, if the antifoaming agent is included in less than 0.3 parts by weight with respect to 100 parts by weight of water contained in the waterproofing mortar for wall finishing, the composition ratio of the antifoaming agent is insignificant, and the bubble removal effect is somewhat insufficient, and when the antifoaming agent exceeds 1 part by weight Although it is excellent in the bubble removal effect, but economical is poor, it is preferably included in the waterproof mortar at a composition ratio of 0.3 to 1 parts by weight.

In addition, the present invention may be configured to further include 1 to 5 parts by weight of the stone having a predetermined average particle size with respect to 100 parts by weight of water-resistant mortar for wall finishing construction.
