For example, the waste paper sludge discharged from a paper mill has a water content of about 70%, but most of the water evaporates in the process of producing the composition. Therefore, a drying step which causes an increase in cost is not particularly required.

The pulverized waste plastic material is melted in a hot press during the production process of the composition, and acts as a binder for paper or wood waste. It is appropriate that the plastic waste is used in substantially the same amount as the paper or wood waste. Since no high-temperature treatment is required in the production 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 since it does not melt around 190 ° C where vinyl chloride melts and flows,
It should be treated not as a binder but as a kind of aggregate, similar to paper or wood waste.

The weight ratio of b: c is 6: 1 to 3: 1 to 3 and 6:

Preferably, if it is 6 or more, curing starts in the mixing and opening machine.
There is a problem in the work, and when it is 2 or less, the effect of addition is almost negligible.

The reason for using together is CaO and silica in alumina cement.

This makes it possible to manufacture fire-resistant boards with high strength.
You. As an example of the former, a mixture called "Fujivoca" developed by the present inventors can be used. This is a fine powder obtained by mixing aluminum hydroxide, sodium silicate and calcium chloride (or magnesium chloride) at a weight ratio of approximately 6: 2: 2. As an example of the latter,
A mixture called "Thomas ceramics" also developed by the present inventors can be used. This is a fine powder obtained by mixing alumina cement and silica powder at a weight ratio of about 1: 1. When a material with high moisture content such as raw paper sludge is mixed with this Thomas ceramics,
At the same time as the hardening occurs due to the hydration of the alumina cement, the free moisture also decreases. The composition of the present invention has a dry weight

For example, the mixture is mixed and stirred while preheating, and then put into a hot press. The temperature of the hot press is maintained at a temperature at which the plastic melts and flows but does not decompose (for example, 150 to 190 ° C.). If necessary, a simple gas cleaning device may be installed.

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

大きいことがわかる。 The boards of Examples 1 to 5 have a flame retardancy rating of 1
And the bending strength is 200 kgf / cm 2 or more, which is sufficiently high. Comparative Examples 1 and 2 were obtained by replacing a part of paper or wood waste with Thomas balloon, and although the flame retardancy was of the first grade, the strength was slightly inferior. The Comparative Examples 3 to
6 is paper and / or wood waste, plastic waste and resistant
Fire additives are out of the composition range of the present invention, the flame retardancy or strength is poor or the unit volume weight is
It turns out that it is big.

る。As the present invention effectively utilizes paper or wood waste and plastic waste which are discarded in large quantities, it contributes to solving environmental problems, is very economical, and has low bending strength. It is possible to obtain a board that is large, lightweight, and excellent in fire resistance of the first class of flame retardancy.
