- these crystals are not considered to be strength-generating substances themselves, for example, they increase the hardness and density to improve compressive strength and suppress crack propagation. It is thought that there is an effect.
- the content of the crystal is preferably 1 to 50% by weight based on the total weight of the amorphous powder. This is because if the number of crystals is too small, the above effect cannot be obtained, and if the number is too large, the strength is reduced.
- the A 12 0 3 - S i 0 2 based crystal compound is Hydrogen Aluminium Silicate, Kaolinite, Zeolite, A 1 2 0 3 one C a 0 based crystalline compound of Calcium Aluminate, C aO- S i 0
- the crystalline compound of the 2 system is Calcium Silicate ⁇ A 12 0 3 — S i ⁇ 2 — Ca

- halogen may be added to an amorphous body composed of two or more oxides.
- This halogen acts as a catalyst for the solid solution and hydrate formation reactions, and also acts as a combustion inhibitor. Its content is desirably 1 to 1.2% by weight based on the total weight of the amorphous body. This is because if it is less than 0.1% by weight, the strength is low, and if it exceeds 1.2% by weight, harmful substances are generated by combustion.
- the halogen chlorine, bromine, and fluorine are preferable.
- calcium carbonate (Calcite) may be added.
- Calcium carbonate itself is not a strength-expressing substance, but it is thought that the surrounding of calcium carbonate with an amorphous body contributes to strength improvement by preventing cracks from developing.
- the content of the calcium carbonate is desirably 48% by weight or less based on the total weight of the amorphous body. The reason is that the bending strength decreases when the content exceeds 48% by weight. Because. Further, it is desirable that the content be 0.1% by weight or more. If the content is less than 0.1% by weight, it does not contribute to the improvement in strength.
- the amorphous powder of the present invention desirably has a specific surface area of 1.6 to 20 Om 2 Zg.
- a composite cured product is produced by solidifying amorphous powder through a binder, if the specific surface area of the powder is less than 1.6 m 2 / g, the contact area between the binder and the powder is too small. Compressive strength and flexural strength decrease. Conversely, if it exceeds 20 Om 2 Zg, the powder becomes too fine, and compressive strength and flexural strength also decrease. Therefore, by adjusting the specific surface area of the amorphous powder within the above range, a composite cured product having excellent compressive strength and bending strength can be obtained. If the specific gravity of the amorphous powder is less than 2.2, the hardness and strength are low, while if it exceeds 3.0, the powder becomes brittle and conversely decreases in strength. It is preferable to be within the range.
- amorphous powders are used in various industries, for example, fillers for decorative boards, raw materials for inorganic boards, filter materials, column packing materials for chromatography, catalyst carriers, raw materials for human bones It can be used as a prosthetic material, a resin filler for sealing electronic parts, a filler for a resist composition, and the like.
- papermaking sludge is a pulp residue containing inorganic substances, which is low-cost because it uses industrial waste as a raw material, and contributes to solving environmental problems.
- This papermaking sludge is desirably fired at 300 ° C. or more and less than 800 ° C. That is, when the temperature is 800 ° C. or more, the material tends to be crystalline, and when the temperature is less than 300 ° C., the pulp is only carbonized and powder cannot be obtained.
- An amorphous structure can also be obtained by baking the papermaking sludge at 300 to 150 ° C.
- papermaking sludge in addition to pulp, A, Si, Ca, Na, Mg, P, S, K, Ti, Mn, Fe, Zn, etc., oxides, hydroxides or sols that are precursors of these, or Complex and halogen and carbonate calcium It generally contains at least one selected from water and water.
- high-quality waste paper contains a large amount of calcium-based crystals such as calcium carbonate and calcium carbonate. Therefore, papermaking sludge containing a large amount of waste paper is suitable.
- the water content in the papermaking sludge is desirably 20 to 80% by weight. This is because if the water content is less than 20% by weight, the material becomes too hard and molding becomes difficult, while if it exceeds 80% by weight, it becomes a slurry and molding becomes difficult.

- HiAkirashitsukotai 248 by kneading the papermaking sludge 1 5 1 2 parts by weight parts by weight and green, while conveying the kneaded product in the conveyor, a pressure of 3 kg FZC m 2
- a sheet-shaped molded product having a thickness of 10 mm was obtained.
- the sheet-shaped molded body was heated at 100 ° C. to obtain a plate-shaped composite cured body.
- the amorphous powder obtained by ball milling in Example 4-11 was further ball milled for 48 hours to obtain 248 g of amorphous powder.
- this amorphous powder was analyzed using a fluorescent X-ray analyzer (RIX2100, manufactured by Rigaku), the composition was as follows in terms of oxide.
- Example 4 The fired product obtained in 11 was ball-milled for 10 minutes to obtain 248 g of amorphous powder. This amorphous powder was analyzed using an X-ray fluorescence spectrometer (RIX2100, manufactured by Rigaku). The result was the following composition in terms of oxide.
- the sheet-like glass fiber was impregnated with a finol resin solution containing a curing agent (impregnation amount: 45% in terms of solid content), and then dried at a temperature of 80 ° C for 20 minutes to obtain a reinforcing sheet.
- a sheet-like molded body was produced in the same manner as in Example 4-1. Then, the reinforcement sheet is placed on the front surface and the back surface of the sheet materials, at a temperature of 1 1 0 ° C, and pressed at pressure 7 kg fZcm 2 20 minutes, the reinforcement 1 mm thick in both sides A composite building material consisting of layers and a core of thickness i Omm was produced. Furthermore, a decorative veneer of 0.2 mm cedar board was attached to the surface of the composite building material via a vinyl acetate adhesive.
- a slurry was prepared by mixing 60 parts by weight of fired scum, 36 parts by weight of water, 100 parts by weight of cement, and 0.3 parts by weight of vinylon fiber for 3 minutes with a forced stirring mixer, which was fired at 1,000 ° C. It was poured into a mold, pressurized at 150 to 180 kgf / cm 2 , and then demolded. X-ray diffraction measurement was performed on the powder collected from the plate, and Gehlenite, syn, Melitite-synthetic, Gehlenite-synthetic,
- the flexural strength, compressive strength, workability, and nailability of the composite cured material or composite building material obtained in the above Examples and Comparative Examples were tested.
- the results are shown in Table 4.
- the test method was measured according to the flexural strength specified in JISA 6901, and the compressive strength measured in accordance with the method specified in JISA 5416.
- the workability was determined by cutting with a circular saw for woodworking.
- nailing was performed with a nail of 4 mm in diameter and 50 mm in length, and the penetration depth of the nail and the presence or absence of cracks were examined.
- the composite cured product manufactured using the amorphous powder of the present invention is an inexpensive material having excellent workability and productivity, and having high bending strength, and is therefore inexpensive in various fields. It is possible to provide the most suitable material for building materials at a low cost because it can be applied advantageously, and in particular, it can drive nails.
