However, a part of the waste material that has been used as a building material and the destructive material caused by cutting during construction work is crushed. For example, if it is a crushed product of calcium silicate plate, a calcium silicate plate is manufactured. At this time, if it is a slate waste material crushed product, it is utilized for each material as an extender when manufacturing slate, but the addition amount is usually about 5% by weight, at most about 7% by weight, There is a limit to the amount of use because the performance of the building materials produced decreases as the amount added increases.

It is preferably within the range of 60% by weight. Here, when the amount of the binder compounded is large, the strength of the obtained plate-like recycled building material or plate-like composite recycled building material increases, but from the standpoint of recycling inorganic building material waste materials, It is not preferable because the amount of waste construction materials used is small and the recycling efficiency becomes poor. On the contrary, if the amount of the inorganic building material waste material is increased, the strength of the plate-like recycled building material or the plate-like composite recycled building material decreases and becomes unfavorable as a building material within the above range.

Is preferred. Here, when the amount of the reinforcing fiber is more than 5 parts by weight, the fibers are entangled with each other during the mixing of the raw materials to form a fiber ball shape or the like and the dispersibility is significantly deteriorated, and the effect of the reinforcing fiber cannot be exerted, and the cost is reduced. It is not preferable because of the drawbacks such as high cost. When used as a core material for a plate-like composite recycled building material, face materials are provided on both sides of the core material, and since the face material has high strength, it is not necessary to mix reinforcing fibers.

乾燥状態の原料混合物を得る。The method for producing the plate-like recycled building material of the present invention will be described in more detail. First, a pulverized product of waste inorganic building material, a binder and a reinforcing fiber are weighed at a predetermined ratio and put into a mixer or the like to be dry-processed. Mix evenly with. When the reinforcing fiber is added, it may be solidified into a fiber ball state depending on the type of the reinforcing fiber. Therefore, it is desirable to appropriately select the addition method and the mixer to uniformly disperse the reinforcing fiber. Next, while dry mixing, a predetermined amount of water is added and mixed until sufficiently dispersed. If you add water randomly,
It is desirable to add water in a nebulized state as the mixture will be in a step state. Further, when the binder is liquid, it is desirable that the liquid binder and a predetermined amount of water are mixed in advance, and this mixture is added and mixed in a spray state. In this way, a semi-dried raw material mixture is obtained.

により本発明の板状再生建築材料を得ることができる。Next, the obtained semi-dried raw material mixture is put into a mold having a desired shape and pressure-molded. The molding pressure of the pressure molding is related to the density and bending strength of the plate-shaped recycled building material. When the molding pressure is low, the density and bending strength are low. On the contrary, when the molding pressure is large, both the density and the bending strength are large. Therefore, set the density and bending strength according to the purpose and purpose of the obtained plate-shaped recycled building material,
It is preferable to select the molding pressure. After pressurization, the pressure is released, the product is taken out of the mold, and curing is performed until the obtained molded product is cured. The curing and curing conditions differ depending on the binder used, and it is desirable to carry out the curing at the optimum temperature and time for curing the binder. After curing and curing, the plate-like recycled building material of the present invention can be obtained by drying.

点がある。The method for producing the plate-like recycled building material of the present invention is not limited to the semi-dry molding method. For example, a large amount of water is added to the pulverized waste of the inorganic building material, the binder and the reinforcing fiber. Alternatively, the paste may be formed into a paste, and the paste may be formed by pressure dehydration molding or a method in which a larger amount of water is mixed to form a slurry and the slurry is wet-paper-formed. However, in each case, compared to the semi-dry molding method, since the amount of water used is large, there is a drawback that treatment of water and drying of the obtained molded body are time-consuming and costly.

Generally, a plate-like construction used as a building material The material has a width of 910 mm or more. In the molding by the extrusion molding method, when the width exceeds 600 mm, the extrusion speed in the width direction at the time of molding slightly changes and the molded body meanders or cracks, so it is difficult to obtain a normal plate-shaped molded body. .

It should be noted that the surface material may be used after applying makeup, but it is difficult to manufacture while protecting the makeup surface so that it does not scratch or the like.

ましくない。In the plate-like composite regenerated building material of the present invention, a face material having an adhesive applied in advance on the surface in contact with the raw material mixture of the face material is installed at the bottom of the mold having a predetermined shape, and the face material is placed on the face material. By adding the raw material mixture that forms the core material, and further installing the face material to which the adhesive is applied in advance on the surface of the face material that contacts the raw material mixture, the raw material mixture is semi-dry molded together with the two face materials. It can be manufactured. As the adhesive used for adhering the raw material mixture to be the face material and the core material, polymer cement, water glass adhesive, vinyl acetate adhesive, urethane adhesive, etc. can be used, and the amount of adhesive applied is , 50-2 depending on the material used for the face material and core material and the type of adhesive,
It is preferable to apply it at a rate of 00 g / m 2 . Here, if the amount of adhesive applied is less than 50 g / m 2, it is not preferable because the adhesive force cannot be exerted and the face material and the core material are peeled off to lose the effect as a composite material.
If it exceeds / m 2 , the coating amount becomes unnecessarily large and further improvement of the adhesive force cannot be expected, and only the cost increases, which is not preferable.

用が掛かる欠点がある。The method for producing the plate-shaped composite recycled building material of the present invention is not limited to the semi-dry molding method.
For example, as in the case of manufacturing a gypsum board, the paste of the raw material mixture is put between the face materials and the roll pressure molding can be performed to obtain a molded body. However, in this case, compared to the semi-dry molding method, the amount of water used is large, so that there is a drawback that it takes time and money to treat the water and dry the obtained molded body.
