In other words, in the wall coating material according to the present invention, 55 to 90% by weight of wood powder is used as the main material, and natural additives such as starch, a small amount of fungicide or preservative, powdery flame retardant, and pigment are mixed appropriately.

The mixture is based on the weight of wood powder, for example, 20 wt% or less, powdery mildew inhibitor or preservative 4 wt% or less, powdery flame retardant 15 wt% or less, powdered natural pigment 6 wt% or less. Mix appropriately. In addition, wood powder as the main material may be appropriately mixed and used according to the request of fine unevenness of the surface of the wall surface to be painted. For example, two or three types, if necessary, of the size of 120 mesh, 200 mesh and 300 mesh transmission (mesh pass), and further, 400 mesh, 500 mesh transmission, and the like are combined and blended. By this formulation, fine irregularities are formed on the surface of the coating, so that there is a change so that a warm wall surface can be obtained.

The wall coating material may be mixed and stirred with about 5 to 7 times water to form a cement or paste, and may be formed on a sheet surface of a sturdy paper or fibrous cross or a nonwoven fabric and dried to form a wallpaper. The application described in the present invention may be any one of brushing, iron coating, painting with a spray gun, and the means is not particularly limited. In this way, the quantity to apply can be apply | coated 5m <2> -6m <2> per 1 kg of coating materials, and if it is thin, 10m <2> can be apply | coated. The thickness is about 1 to 2 mm. The coated wall coating material is dried and solidified in the state which apply | coated to the sheet | seat with the containing agent. Once solidified, even if water is splashed by the hardening effect of a foaming agent, it does not fall and does not become a stain. Therefore, it is also possible to use it as an exterior wall material. Therefore, it can also be used for the marking of soil walls.

In addition, the wall coating material kneaded with the above-mentioned water can be surface-decorated by applying it to the surfaces of building wooden boards, various metal plates, rods, pipes, concrete blocks, bricks, wood panels, gypsum boards and the like as described above. The wallpaper and the building material thus formed are soft and warm to the touch and time, and also have excellent breathability, moisture absorption, and moisture proof performance.

The species of wood as a raw material for wood powder is not limited, but any of conifers such as cypress, cedar and pine, and hardwoods such as beech, prunus oak, oak and cherry can be used. Their wood meal mainly uses thinning or waste wood. In addition, sawdust from a sawmill, etc. can also be used. Although it is preferable to use the thing of predetermined particle size as a reuse of a resource, it can also be manufactured by grind | pulverizing a cutting material in the form of fine particles with a grinding device.

It is preferable that the mixing agent to be mixed with the wall coating material is starch, for example, rice flour, flour, starch of potatoes, etc. are preferable because it is easy to obtain cheaply. Moreover, you may add and use the seaweed paste made into powder form as a kind of this favoring agent.

In addition, there are various antifungal agents, preservatives and flame retardants, but it is preferable to market commercially available. Pigments are preferred in that natural mineral powders such as mineral powder pigments or artificial mineral powder pigments based on metallic materials do not emit toxic combustion gases in case of fire, and non-resin materials using natural materials such as plants or trees. It is also preferable to have water solubility.

Effects of the Invention

The wall coating material as used in the present invention is made of wood powder as a main material, and a natural inhibitor for solidifying it, and an appropriate amount of an antifungal agent, an antiseptic, a flame retardant, and a pigment, so that the human body is exposed to a high temperature such as fire or a combustion flame. Because it does not generate harmful gases, it does not cause an accident and has a remarkable effect that it can be used with confidence.

In addition, since the wall or wall material formed by the wall coating material of the present invention does not use a synthetic resin mixture at all, it can be naturally reduced by burying in the soil when disposed of as waste, and even when incinerated, there is no toxic gas. Can be processed. In addition, it is highly breathable, has excellent humidity control to keep the indoor humidity constant by moisture absorption and moisture absorption, and can suppress generation of condensation and water droplets on the surface, creating a comfortable living space suitable for high temperature and humidity climate of Japan.

Best Mode for Carrying Out the Invention

Wood powder, which is the main material of the wall coating material of the present invention, is used by mixing about 120 mesh and 200 mesh permeate into approximately equal parts, for example. When one type of wood powder is used, the surface of the coated surface tends to be formed close to the smooth surface, and when large and small powders are mixed, the small powder tends to sink on the wall surface, and the large powder tends to float on the surface side. There is an advantage that it is easy to form a fine and three-dimensional uneven surface. Dry powder-like foam, mold inhibitor, preservative, flame retardant and pigment are mixed in the wood powder in the following ratio to form a wall coating material.

78% by weight wood powder mixed with 120 mesh path and 200 mesh path, 10% by weight of 20% by weight seaweed paste mixed with rice flour, 2% by weight of mildew and preservative, 2% by weight of flame retardant, rock powder 3 weight% of the natural pigment which consists of was stirred and mixed uniformly, and the powdery wall surface coating material was obtained. This mixing ratio is an example, it goes without saying that it can increase or decrease suitably.

To the wall coating material thus obtained, water of 7 times the weight ratio to the weight of the coating material is added, mixed, stirred and kneaded with a cement stirrer to form a paste, which is requested by a plasterer and placed on a plywood wall during construction as a plastering iron. Was applied. It was able to coat about 9 m 2 with 1 kg of the kneading material. The thickness of the finished coating was about 1 mm.

The kneaded material kneaded with water was also applied by the plasterer on the wall surface of the plaster applied on the earthen wall of the building. After the drying, there was rainfall, so that the painted surface was in direct contact with the rain, but the coated surface did not cause a drop phenomenon, did not cause a disturbance on the surface layer, and did not cause stains due to rainfall after drying.

In addition, the wall coating material obtained as described above was mixed and kneaded and kneaded with water at a volume ratio of 6 times to form a cement or paste, and coated with 1 kg per 5 m 2 on the surface of the fibrous cross, and dried under a room temperature of 20 degrees Celsius. Was produced. The coating thickness after drying was 1.2 mm on average.

In the wallpaper produced in this way, it is hardened in the state adhere | attached strongly to the cross surface by the adhesive contained in the apply | coated wall coating material, The particle of the surface side forms a fine uneven | corrugated form, and the particle of the side which contacted the cross surface crosses. It entered into the fiber and did not fall off from the cross surface. In addition, it has a soft and luxurious texture that is soft to the touch and visual.

In addition, the wall material was formed by directly applying the cement-like kneading material of the wall coating material mixed with the above water to the surfaces of concrete blocks, wood panels, gypsum boards, and the like as described above. Also in this case, similarly to the said Example, the label | sticker material fixing block etc. which were firmly fixed as the wall surface coating material were obtained.
