Description

【発明の詳細な説明】 (産業上の利用分野) 本発明は、建築物の壁等をモルタルや粒状塗装で仕上げ

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to improvement of base plates used when finishing walls of buildings with mortar or granular coating.

(Prior art) Conventionally, as this type of base plate for construction, for example,
As disclosed in Publication No. 20563, a resin paint or a paint mixed with inorganic material particles or powder is applied to the surface of a wooden board so as to form an uneven surface layer,
It is known that the unevenness of the surface layer ensures adhesion with a top coating material such as mortar, thereby eliminating the need for felt paper, lath, etc., and improving the workability of mortar finishing.

(Problems to be Solved by the Invention) However, with the above conventional method, it is necessary to form irregularities on the surface layer, so it is necessary to increase the amount of coating for the surface layer, which causes problems in terms of productivity and cost. At the same time, lff1 became large, which caused difficulties in packaging, transportation, and handling.

In addition, in order to eliminate this drawback,
As disclosed in Japanese Patent No. 5, it has been proposed that an asphalt emulsion is further added to simply roughen the surface layer. However, with this product, the asphalt emulsion is a non-hardening type, and as it gradually dissolves over time and causes poor adhesion with mortar, it is problematic to keep it in stock for a long time, and it also has a paint finish other than mortar finish. When used for this purpose, this asphalt emulsion inhibits the reaction and causes discoloration, which is undesirable.

The present invention has been made in view of these points, and by using hollow aggregates having openings as aggregates mixed into a synthetic resin emulsion, it is possible to prevent the formation of irregularities on the surface layer and to cause quality deterioration over time. To provide a base board for construction that can secure sufficient adhesion to mortar and other paint finishes without any problems.

(Means for Solving the Problems) In order to achieve the above object, the solving means of the present invention is to mix hollow aggregates having openings in a synthetic resin emulsion on the surface of a plate-like base material, or A mixed layer made of fine aggregate is provided. Then, the mixed layer was mixed with a particle size o of 1 to 0.0 to 100 parts by weight (solid content) of the synthetic resin emulsion.
5m hollow aggregate is 10-100 parts by weight, fine aggregate is 200 parts by weight.
Parts by weight or less are mixed, and the hollow aggregate is configured such that 30% or more of the surface area of the plate-shaped base material is exposed.

Further, the hollow aggregate is an inorganic foamed aggregate having openings,
For example, perlite, shirasu balloon, silica balloon,
Among fly ash, those having an average particle size of 0.1 to 0.5 mm are used. This hollow aggregate has an anchoring effect because 6@silica sand (particle size 0.15 to 0.5 mm) is usually used as the finishing mortar aggregate, and this mortar aggregate enters the openings of the hollow aggregate. If the particle size is less than 0.1 mm, it will not be possible to achieve conformation by absorbing the moisture retained in the top coating material, and the anchoring effect will not be achieved due to the intrusion of aggregate in the finishing mortar.
If the particle size is 0.5+nm or more, a continuous layer of the resin will not be formed and the waterproof effect cannot be achieved.
It is preferable to set it within the range of m. It is also possible to use a hollow aggregate of perfect particle size and break the shells to form openings by scraping after application or by sanding after hardening.

Further, as the fine aggregate, cement, silica sand, talc, clay, magnesium hydroxide, calcium carbonate, magnesium carbonate, etc. are used, and those of 65 mesh or more are preferable because they have a sealing and filling effect.

Next, we will discuss the mixing ratio of hollow aggregate and fine aggregate to 1 part (solid content) of 100 ml of the above synthetic resin emulsion.If the hollow aggregate is less than 10 parts ffi, the above-mentioned water absorption and anchoring effects will be insufficient. On the other hand, if it is 100 parts by weight or more, the water permeability increases and the water impermeability (waterproofing) of the mixed layer cannot be ensured, so it is set at 10 to 100 parts by weight. In addition, there may be no fine aggregate, but there is no fine aggregate (zero).
If this is the case, the impregnation of the resin into the base material will be large and there will be no sealing effect, so it is preferable to mix it in from the viewpoint of cost reduction and productivity improvement. But 200! If the amount exceeds 200 parts by weight, water permeability increases, so the amount is set at 200 parts by weight or less.

In addition, the exposure ratio of the hollow aggregate is 3 of the surface area of the plate-shaped base material.
If it is less than 0%, the above-mentioned anchoring effect cannot be sufficiently exhibited, so it is set to be more than 30%.

Furthermore, the above-mentioned mixed layer can be formed by scraping the surface with a reverse coater, blade coater, etc. in order to expose the hollow aggregates on the surface during the coating process, but if the resin layer is applied in advance, the hollow aggregates The aggregate may be spread and buried, or openings may be provided in the hollow aggregate by polishing or the like after hardening without scraping during the coating process, or the exposure ratio may be increased. Furthermore, although this coating film is slightly raised in areas where the hollow aggregate is exposed on the surface, it is applied to a thickness of 100 to 500(]/T[l'').

After this application, the coating is dried for 1 to 5 minutes (for example, using a hair dryer at 100 DEG C.) and cured to become ready for deposition.

(Function) With the above configuration, in the present invention, hollow aggregates having openings are exposed on the surface of the mixed layer, and the particle size thereof is 0.1 to 0.5.
Since the material is nym, this hollow aggregate absorbs moisture in the top coating material (mortar, etc.) and improves its adhesion, as well as promoting the penetration of the top coating material aggregate into the openings of the hollow aggregate. This increases the adhesion (anchoring effect) with the top coating material and improves adhesion.

Moreover, since a curable resin is used, the quality is maintained stably and well for a long period of time, and there is no deterioration over time, and it can be used for paint finishes other than mortar finishes.

Further, since the mixed M (resin layer) is continuously formed on the surface of the base material, water does not penetrate to the base material, and good water impermeability is ensured.

Perlite is 201f1 part per 100 parts by weight of SBR,
A mixture of 200 parts by weight of cement was applied at 200 g/m'' (wet) using a reverse coater, and then dried at 100°C for 2 minutes to form Barley 1 with openings on the surface.
A mixed layer was formed in which ~ was exposed. On the other hand, as comparative examples, there is one in which pearlite is removed from the above example (Comparative Example 1), and one in which a waterproof layer is applied and formed on plywood, and an uneven cement layer of approximately 1500+J/TT+' is provided (Comparative Example 2). ) and prepare 10 pieces of mortar for these 8 cases.
After applying M and curing for 7 days, mortar adhesion test (J
