Description

  The present invention relates to a paint, and more particularly, to a paint excellent in incombustibility and decorativeness.

  Conventionally, on the wall of a house, vinyl cloth such as vinyl chloride is pasted on the wall of the house, Japanese paper is pasted in the case of a Japanese-style room, and further, plaster, diatomaceous earth, etc. are used for the painted wall. In particular, vinyl cloth is most widely used at present because it is inexpensive, can be easily repositioned, and can easily change the image of a room.

  However, although vinyl cloth has various advantages, it is a chemical product made from petroleum, so it produces a large amount of toxic gases such as carbon monoxide during combustion, compared to wall materials made of natural materials. It is inferior from the viewpoint of global warming prevention.

  In Japan, there are 60,000 fires per year, of which 60% are building fires, more than 30,000. Along with this, non-flammable and safe housing is required to protect human lives and property.

  Therefore, the present invention provides a paint that can be used for walls and ceilings of houses as wall coverings and ceiling materials, is nonflammable, inexpensive and safe, and has excellent decorative properties. Objective.

  In order to achieve the above object, the present inventor has found that the incombustible paint can be obtained by mixing boric acid or / and borax and a binder as a result of intensive studies. It came to an eggplant. That is, the present invention is a paint, characterized in that boric acid or / and borax and a binder are mixed. Thereby, it is possible to provide a paint that is inexpensive, safe, and excellent in incombustibility.

  In the coating material, the borax can be pulverized and mixed with the binder. Thereby, the coarse borax can be atomized to provide a fine-grained paint with good workability.

  Moreover, sodium polyborate can be further mixed with the coating material, and the nonflammability can be further improved.

  In addition to the above coating materials, at least one of wood powder, shell powder, stone powder, sand, earth, paper, and fibers can be mixed as a powder material, and in addition to nonflammability, a coating material excellent in decorativeness is provided. In particular, by mixing wood flour, the weight can be reduced and the air permeability can be improved in addition to the improvement of the decorativeness. In addition, the powder material may be used as it is, or a decolored and / or colored powder material can be used. By changing the mixing ratio of the powder material, it can be used for a wide range of applications such as paints and coating walls. can do.

  In the paint, a colorant can be mixed before or after the powder material is mixed, and the decorativeness can be further improved.

  As described above, according to the present invention, it is possible to provide a paint that can be used for a wall or ceiling of a house as a wall covering material, a ceiling material, etc., is inexpensive and safe, and has excellent incombustibility and decorativeness. it can.

  Next, the form for implementing this invention is demonstrated.

  As described above, the present invention is a paint, and is characterized by mixing boric acid or / and borax with a binder. Here, borax can be used as it is, but since the particles are coarse, it can be mixed with the binder at a higher density by pulverization, and the nonflammability function can be improved. Specifically, by using borax pulverized to a particle size of 1000 μm to 1 nm, preferably 100 μm or less, a fine and fine paint with good workability can be obtained. By containing it in high density, the nonflammability of the paint can be improved. In addition, borax can be adjusted to the said particle size by grind | pulverizing, crushing, and super finely grinding | pulverizing using grinders, such as a high pressure homogenizer, a jet mill, and a bead mill.

  On the other hand, a vinyl acetate resin emulsion type can be suitably used for the binder. Besides this, an aqueous polymer-isocyanate type, epoxy resin type, acrylic resin type emulsion type, modified silicone type, vinyl copolymer resin can be used. Emulsion type, urethane resin type, rubber type latex type, synthetic resin type emulsion type, synthetic rubber type latex type, epoxy modified synthetic rubber type latex type, etc. be able to. However, the use of urea resin, melamine resin, and phenol resin, which may adversely affect the human body, should be avoided.

  In addition, incombustibility can be further improved by mixing sodium borate in addition to boric acid or / and borax and a binder. Sodium polyborate can be mixed as an aqueous solution or impregnated in a powder material described below.

  The above-mentioned paint is prepared by blending each material from the viewpoint of a non-combustible paint, and can further be provided with a decorative property by mixing a colorant. For the colorant, various materials such as dyes and pigments can be used, which may be added to the binder before mixing with boric acid or / and borax, or added to the mixture of boric acid and the binder. You may mix.

  In addition, in order to improve decorativeness, powder materials such as wood powder, shell powder, stone powder, sand, earth, paper, and fibers are mixed with the above noncombustible paint in addition to or without adding a colorant. Can do. Further, after the powder material is mixed with the noncombustible paint, a colorant may be further mixed.

  Each said powder material may be mixed independently and may use 2 or more types simultaneously. The particle diameter of the powder material is about 10 mesh to 500 mesh, preferably 50 mesh to 300 mesh, and the particle diameter of the borax powder is considered to be smaller than these. This is to contain borax at a high density so as not to impede its incombustibility. It is also possible to use decolorized or / and colored powder materials.

  In particular, when wood powder is used, the sodium polyborate has a non-combustible effect of wood powder, so that the non-combustibility of a paint mixed with wood powder can be improved. At this time, the wood powder may be impregnated with sodium polyborate. Even when wood powder is used, sodium polyborate is not essential, and this may not be used. In addition, wood powder is preferable for reducing the weight of the paint, and has an effect of improving air permeability.

  In the production of the paint, when not using powder materials, the ratio of each material as shown in Table 1, and when using powder material, the ratio of each material as shown in Table 2. And then mixed and stirred with a mixer, a stirrer or the like. Specifically, the mixing ratio can be set as shown in Table 3, and in addition to the basic mixing, the sodium polyborate, the colorant and the like can be appropriately mixed. When mixing wood flour, it can be considered environmentally friendly by using wood flour from thinned wood. In addition, the mixing ratio of each said material is an illustration, Comprising: It has a certain amount of width centering on the said mixing | blending, and can be changed suitably. Also, oil or a mixture of water and oil can be used in place of water, and a paint having the above characteristics can be produced without using water or / and oil.

  Paints produced as described above are sold in storage containers such as cans, bottles, plastic containers, standing pouches, refillable pouches, single-use packs, etc., just like ordinary paints. It can apply | coat to a ceiling etc. using a trowel, a brush, or a roller.

  The embodiment of the present invention has been specifically described above. However, the present invention is not limited to the present embodiment, and various modifications can be made without departing from the gist of the present invention. Of course it is possible.
