I have proposed a lot. When these are roughly classified, a cement-based solidifying agent is used for a wet material, and a melamine resin or the like is mainly used as a binder for a dry material. Even if they are reasonable in their own way, it is hard to say that they have always obtained satisfactory results due to differences in products obtained.

い。In the case of producing the composition of the present invention, paper waste materials such as waste paper and papermaking waste materials and essential waste materials such as wood chips, sawdust, and citrus can be used even in a dry state, but when a large amount of water is contained. However, it can be used as it is without drying. For example, the water content of raw waste paper sludge discharged from a paper mill is about 70%, but most of the water content evaporates in the manufacturing process of the composition. Therefore, there is no need for a further drying step which causes a cost increase.

The crushed material of the plastic waste material is melted in the hot press during the production process of the composition and acts as a binder for the waste material of paper or wood. It is appropriate to use the same amount of plastic waste material as paper or wood waste material. Since no high temperature treatment is required in the manufacturing process of the composition, no toxic gas is generated from the plastic waste material. Urethane foam waste can also be used as plastic waste, but this does not melt near 190 ° C when vinyl chloride melts and flows,
It should be treated as a kind of aggregate like paper or wood waste, not as a binder.

A mixture of (b ') is used. As the former, it is possible to use a mixture developed by the present inventor and referred to as "Fujivocaa". This is aluminum hydroxide, sodium silicate and calcium chloride (or magnesium chloride)
Is a fine powder in which the weight ratio of about 6: 2: 2 is mixed.
Also, as the latter, a mixture called "Thomas ceramics" also developed by the present inventor can be used. This is a fine powder in which alumina cement and silica powder are mixed in a weight ratio of about 1: 1. When a material having a high water content such as raw waste paper sludge is mixed with this Thomas ceramics, hardening occurs due to the hydration of alumina cement, and at the same time, free water also decreases.
【００１０】本発明の耐火性ボードの製造方法の一例を

砕分離する。First, raw papermaking sludge (water content of about 70%, or dried one) or wood waste (residual material of old wooden house or annual plant stem) is roughly ground with a crusher. After that, the planer with many needle-shaped blades is rotated to loosen it into fine fibers like cotton, and then crushed and separated by a crusher.

For example, while preheating, after mixing and stirring, put into a hot press. The hot press temperature is maintained at a temperature (for example, 150 to 190 ° C.) at which the plastic melts and flows but does not decompose.

The plastic (raw material B) melts into a fluid state, covers the surfaces of the particles of the raw material (A) and the refractory additive (C) that are uniformly mixed, and the preparation for the three-part integral is completed. Here, a pressure of about 40 to 50 kg / cm 2 is applied by a press to mold, and then a cooling / finishing step is performed. The fragments cut off at the time of finishing are again charged into the needle-shaped planer of the flow of the raw material (A) and pulverized into a cotton-like shape to become a part of the raw material. Therefore, no waste is generated from the manufacturing plant.
