Field of the Invention The present invention relates to a solidifying agent for coating materials for buildings and a method for producing coating materials, and more specifically, it is suitable mainly for use on wall surfaces of buildings, and is hard, water resistant and fire resistant. TECHNICAL FIELD The present invention relates to a solidifying agent for a building coating material for obtaining a coating material for a building capable of imparting properties, and a method for producing a building coating material using the solidifying agent.

リマーディスバージョンを土に混入して塗材を補強する
方法が取られるようになっている。BACKGROUND OF THE INVENTION There are various conventional coating materials for buildings. However, in the case of a coating material for earthen wall, which is widely used in traditional Japanese-style architecture, if this is used for the outer wall, there is a problem that the coating material will be stripped off due to wind and rain, and the appearance will be significantly impaired. Therefore, in recent years, a method of reinforcing a coating material by mixing a cement-mixing polymer dispersion into soil has been adopted.

水性にする材料の固結剤は開発されていなかった。However, when the polymer admixture for cement admixture is incorporated into a coating material to withstand wind and rain, the hue of the soil changes, so a method of admixing the polymer admixture for cement admixture into colored sand is adopted. But,
A solidifying agent for a material that retains the shape, hue, etc. of a soil wall using traditional soil and is water resistant has not been developed.

い内外壁に使用できる左官用塗材が少なかった。Further, crushed stones are mixed with cement and lime to wash out artificial stones, and painting of suspicious stones has been widely used for plastering work. , Recently, the plastering work is on the decline. At present, there are few plastering coating materials that can be used for inner and outer walls, which are inexpensive and have good workability, since corrosion-resistant mortar and refractory mortar that does not generate toxic gas at the time of fire are required.

る。By the way, in the field of civil engineering and construction, water glass is mainly used as a soil improving material, a refractory mortar, a cement quick-setting material, a paint, etc., and in some cases, a construction method of spraying a coating material is performed. However, due to the following reasons, it was rare to use it as a finishing material for inner and outer walls by mixing it with clay, crushed stone, and other materials used in conventional plastering work. That is, it is necessary to use a curing agent due to poor water resistance,
It is difficult to control the usable time of the curing agent, and it takes time from kneading to the end of coating. Since it has high water permeability and air permeability, it lacks waterproofness. If no curing agent is used, it is necessary to avoid rainwater for about 20 days after application. The coating material is not glossy and is not suitable as a finishing coating material.

る。The mixing and mixing of the solidifying agent and the main material (aggregate) is usually carried out by heating a predetermined water glass alone or in combination and aging it for 5 hours or more, and a polyethylene emulsion ( Alternatively, a paraffin emulsion), a sizing material (CMC), and a curing agent are mixed, and then a polymer mixture for cement mixing is mixed to obtain a coating material. Here, by mixing a polyethylene emulsion or a paraffin emulsion, the coating material exhibits an initial hydrophobic property and an effect of preventing efflorescence.

Depending on the particle size of crushed stone and glass beads, calcium carbonate may be mixed in 10 to 30% of the amount of aggregate.

This is because it was considered that the crack generation rate was high when the amount of lithium silicate mixed was increased. Also,
When the main material is colored sand or crushed stone, a combination of an aqueous solution prepared by changing the ratio of sodium silicate, potassium silicate, and lithium silicate and a known curing agent, sizing agent, and polyethylene emulsion is preferable. Depending on the particle size of the material used, it is necessary to add fine stone powder to adjust the particle size of the aggregate and change the amount of glue and the mixing ratio of sodium silicate, potassium silicate, and lithium silicate.

For example, in the case where a natural crushed stone with a diameter of 0.8 mm or less is mixed with 20% of finely powdered stone powder as the main material, the above-mentioned solidifying agent is mixed and a composite coating material is used to coat stones, Suspicious stone coating is applied with a trowel, and it is closer to natural stone than artificial stone washed out simply by pressing down with a trowel, and because it has air permeability and water permeability, it is peeled off even if water penetrates from the back side like a block wall It has the effect of not doing. In this case, the surface may be coated with a water-repellent paint or the like depending on the application.

To work. In addition, in the repair work of the storehouse, in order to strengthen the deteriorated wall soil by replenishing it with the solidifying agent impregnated in this example, a sand plaster is applied on top of it and a net is applied, and the repair work with a top coat has a good result. Acts to obtain. Furthermore, plaster plaster, which plasterers are familiar with, can be used as if painting sand walls, it is technically simple, and the working speed is 1/2 ~ compared with artificial stone washing when suspicious stone painting is done.
It can be shortened to 1/4 and the material cost will be cheap because of thin coating.

That is, a coating material mixed with a solidifying agent having an aqueous solution which is obtained by diluting water glass and heated and aged at 30 to 100 ° C. and a solidifying agent mixed with an unheated aqueous solution is applied to the wall surface of the building. After repeating the water resistance test of the coating material after soaking it in water 24 hours later, it is clear that the "coating material mixed with the heated aqueous solution" did not soften or change in hue and the curing time could be shortened. Coating material mixed with non-heated aqueous solution "
In the case of, the water resistance is inferior, and if the curing agent is not added,
Curing was not obtained and a change in hue was observed unless it was done for about 20 days after coating. Even if the curing agent has a short usable time, CMC
It was found that the usable time can be adjusted by mixing it with a paste or thickener such as. That is, since the curing agent does not come into direct contact with the aqueous solution of water glass due to the barrier property of CMC, the curing time can be adjusted, and a small amount of the curing agent can be mixed with CMC to increase the amount, so that the coating material can be easily applied. It can be dispersed uniformly. A thickener can also be used when the hue of the coating material does not matter. It has been found that the addition of a paraffin emulsion and a polyethylene emulsion) imparts gloss and initial hydrophobicity.

果を有する。As is apparent from the above description, according to the method for producing a solidifying agent for building coating materials and coating materials of the present invention, water glass is diluted and heated to 30 to 100 ° C. At the same time, since it is aged at room temperature, the solidifying agent and the coating material for the building coating material obtained by the manufacturing method are softened by themselves,
It has an effect that the hue does not change and the curing time can be shortened.
