BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a photograph showing a process of re-coating an outer wall of a building using a composition for interior and exterior walls according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Although the present invention has been described with reference to the embodiments shown in the drawings, it is to be understood that the technical idea of the present invention and its essential structure and operation are not limited thereby.

Interior composition for interior and exterior walls

First, in order to achieve the object of the present invention, a plaster composition for building interior and exterior walls according to an embodiment of the present invention comprises 40 to 70% by weight of a filler based on the total weight of the composition; 15 to 40% by weight of a binder; 3 to 10% by weight of active agent; And solvent balance.

The filler should be included in the above range within the total weight of the composition to effectively satisfy the surface filling and hiding power. On the other hand, the binder must be contained within the above range within the total weight of the composition to effectively meet the water resistance, adhesion and strength. Meanwhile, in the present invention, the active agent refers to a dispersant, a waterproofing agent, a viscosity stabilizer and the like. If the active agent is included in the total weight of the composition within the above range, the workability and storage stability and leveling property of the product can be effectively exhibited.

This will be described in more detail below.

The filling material is included for the purpose of imparting a surface filling property and a hiding power to the interior and exterior wall composition according to the present invention. The filling material according to one embodiment of the present invention is a feldspar, a talc, a wollastonite wollastonite, calcium carbonate (CaCO3), fine powdery silicic acid (SiO2), alumina (Al2O3), aluminum hydroxide (Al (OH) 3), magnesium oxide (MgO) and kaolin clay To 4 species.

More particularly, in one embodiment of the present invention, the filler is a combination of feldspar and talc or a combination of feldspar, talc and wollastonite. When the filler is a combination of feldspar and talc, the feldspar and talc may be contained in a weight ratio of 7: 3 to 8: 2. When the filler is a combination of feldspar, talc and wollastonite, 2: 1 to 6: 2: 2.

When fillers are used in combination and weight ratio as described above, they have better workability than existing surface treated plasters and have a reduced loss ratio. The fillers are also improved in hiding and surface filling properties compared to conventional plaster.

The binder is included for the purpose of imparting water resistance, adhesion strength and strength to the interior and exterior wall plaster compositions according to the present invention. The binder according to an embodiment of the present invention may be selected from organic binders, inorganic binders, And more specifically may be a mixture of two kinds of organic binders and one kind of inorganic binder.

In one embodiment of the present invention, the organic binder may be at least one selected from the group consisting of methyl methacrylate, butyl acrylate, and mixtures thereof. The methyl methacrylate may be a copolymer having a molecular weight of 6 to 80,000, and the butyl acrylate may be a copolymer having a molecular weight of 7 to 100,000.

In one embodiment of the present invention, the inorganic binder may be a ceramic binder. The ceramic binder may specifically include at least one component selected from the group consisting of silicon, alumina, and a mixture thereof. When the inorganic binder containing the constituent component is contained in the ceramic composition, The dust generation is reduced compared to the prior art, and there is a relatively eco-friendly effect in comparison with a case where a composition using only an organic binder is applied or repainted. On the other hand, the inorganic binder can also serve as a strength reinforcing agent.

Meanwhile, in one embodiment of the present invention, the binder may be used in a weight ratio of 2: 1 to 3: 1 of the organic binder to the inorganic binder. When used within the above-mentioned range, it prevents cracks in the inside and outside walls of the building during painting or repainting and satisfies the hardness required in painting or repainting.

In the present invention, the activator may be at least one selected from the group consisting of a dispersant, a waterproofing agent and a viscosity stabilizer.

The dispersant serves to prevent dispersion and re-aggregation of the filler. According to one embodiment of the present invention, the dispersant may be a polyacrylic acid salt.

The waterproofing agent is an organic waterproofing agent and imparts hydrophobicity to the composition to improve the waterproofing function. According to one embodiment of the present invention, the waterproofing agent is at least one selected from the group consisting of olefins, palmitates, stannates, (Fatty Acid Salt) containing at least one member selected from the group consisting of salts thereof.

The viscosity stabilizer serves to prevent the sedimentation of the constituent components by increasing the viscosity of the composition. According to one embodiment of the present invention, a cellulose viscosity stabilizer containing cellulose as the main ingredient may be used.

Meanwhile, in the fine composition for building interior and exterior walls according to the present invention, the remaining amount of the filler, the binder and the activator may be a solvent, and the solvent may be, for example, water.

As described above, the use of the plaster composition for building interior and exterior walls allows the steps of plastering, plastering, priming and undercoating to be carried out in one step. Therefore, The construction period can be shortened. In addition, by minimizing the moon scaffolding operation, which poses a high risk of accidents, it is possible to reduce the risk of safety accidents during construction.

Method for manufacturing interior compositions for building interior and exterior walls

According to an embodiment of the present invention, there is provided a method for manufacturing a fine composition for building interior and exterior walls, comprising the steps of: a) mixing two or four kinds of fillers; b) adding an organic binder and an inorganic binder to the mixture and adding an appropriate amount of a solvent; c) adding and stirring a dispersant and a waterproofing agent to the mixture; And d) adding a viscosity stabilizer to the mixture and stirring.

First, two to four fillers are mixed (step a). The filler is as described above. When two or more kinds of fillers are mixedly used, there may be some difference depending on the combination of the fillers and the weight ratio of the fillers. However, the filler is more excellent in workability than the conventional surface- And has an improved effect on the surface and the coverability compared to the conventional plaster.

Next, an organic binder and an inorganic binder are added to the mixture, and an appropriate amount of solvent is added thereto (step b). The organic binder and the inorganic binder used are as described above, and water can be used as the solvent. On the other hand, an appropriate amount of solvent means that the solvent contains 40 to 70% by weight of the filler, 15 to 40% by weight of the binder and 3 to 10% by weight of the active agent based on the total weight of the composition, .

 Meanwhile, in this step, the inorganic binder is gradually added, because the inorganic binder reacts rapidly with the organic binder to prevent the aggregation reaction from occurring.

Next, a dispersant and a waterproofing agent are added to the mixture and stirred (step c). The dispersant and the waterproofing agent to be used are as described above, and for example, a polyacrylate and a polyvalent fatty acid salt can be used, respectively.

Finally, a viscosity stabilizer is added and stirred (step d), confirming the viscosity of the mixture. The viscosity stabilizer to be used is as described above, and for example, a cellulose-based viscosity stabilizer containing cellulose as a main component may be used. On the other hand, the reason for adding the viscosity stabilizer in the present step is to keep the viscosity constant. For example, when the composition of the present invention is prepared, the viscosity of the composition is maintained at about 30,000 to 60,000 CPS And exhibits an appropriate pliability effect when the composition is applied within the above viscosity range.

How to paint inside and outside walls

Using the plaster compositions for the interior and exterior walls as described above, it is possible to carry out the plastering, plastering, and undercoating steps in one step.

More specifically, conventional exterior wall paint or repainting work involves smoothing the surface of the inner wall or outer wall (selecting the surface), then laying out the cement mortar and finishing step (step 1), filling the inner wall or outer wall A first painting step (step 3) in which the paint is primed as a priming paint, a putty step (step 2), a second painting step (step 4) in which paint is enameled as a finish paint (step 4).

In the first stage of the above step, as in a high-rise apartment building, a cage (CAGE) for the installation / dismantling of an outer wall formwork and a plastering / plastering work (cage) Since it is relatively safe because it is carried out within the form of a gang form (Gang Form), the second to fourth stages correspond to a suspended scaffold operation, so there is a relatively great risk of a safety accident.

On the other hand, by using the plaster compositions for building interior and exterior walls according to the present invention, it is possible to obtain both the effects of laying, plastering, putty and undercoating by simply coating one composition on the inner wall or outer wall of the building Therefore, it is possible to shorten the construction period by reducing the painting or repainting construction steps to the inner or outer wall of the building, which had previously been done in four steps, to two stages, and minimize the risk of accident .
