Abstract

Incombustible paperboards with high strength and durability were prepd. from paper sheets and incombustible adhesives. The adhesives which composed of a mixture of briquet ash powders (90-110mesh) and cement, wheat flour, and formaline with water, were filled between paper sheets, dried at 150≰C, and pressed at normal temp. by a temp. controlling roller. The paperboards were useful in fireproofing materials.

Description

The manufacturing method of special fire retardant Fuji

1 is a perspective view of the present invention.

2 is an enlarged sectional view taken along the line A-A of FIG.

3 is a perspective view of another embodiment of the present invention.

The present invention relates to a method for producing a special nonflammable fuji which is non-flammable and has improved strength and durability.

The application of non-combustible paint to plywood or other interior materials as a conventional non-combustible interior material has the drawbacks that are cumbersome and costly, and in order to eliminate such defects, the paper is made of the bottom and top surfaces, respectively, and the plaster between them. Non-flammable interior plates with overlapping lamps have been manufactured, but they are used only as interior materials and cannot be used elsewhere.

An object of the present invention is to provide a special non-combustible fuji, using a briquette material to solve this drawback, low cost, high incombustibility and soundproofing effect, and also improved strength and durability to be used in various fields as a heat insulating material.

Another object of the present invention is to recycle the briquettes, which are wastes, as a resource, as well as to prevent environmental pollution and waste disposal.

The present invention for this purpose will be described in detail with reference to the accompanying drawings,

First of all, the special non-flammable adhesive used in the present invention is pulverized completely burned briquettes into 90-100 mesh (mesh), and then mix the cement evenly at a ratio of 8: 2 (volume ratio) to maintain a temperature of 10-20 ℃ While adding a small amount of water and a small amount of formalin and flour, mix while adjusting the viscosity.

This special non-combustible adhesive has high strength and durability as the solidification of cement and briquette materials, and the flour makes the pores of the granules of briquette ash uniformly to smooth the chemical reaction between the cement and briquette materials, and also the non-combustible Fuji It is an organic adhesive that can easily adjust the flexibility and strength of Fuji.

Since such an organic adhesive is contained in a very small amount in the inorganic briquette fines, there is no influence on the nonflammability.

The reason why the special non-combustible adhesive is kept at a temperature of 10-20 ° C. is because the combination of the briquette and cement mixture and the flour is the optimum temperature range.

The special non-flammable adhesive 30 mixed in this way is packed in accordance with the specifications of the Fuji maker and then compressed to improve the strength and durability again. After adhering to the bottom and bottom (2), dry about 70-80% of the moisture in the drying room at 150 ℃, and then dry it again at room temperature and compress it with a temperature control roller to cut it to meet the required specifications.

In the case of manufacturing thicker and harder Fuji, insert middle finger 4 between upper limb 1 and lower limb 2 as shown in FIG. 3 and overlap them with non-flammable adhesives 3 and 5 to further bond This good and thick Fuji can be obtained.

Formalin described in the present invention can be seen as the bactericidal action of the bacteria contaminated in the fine process of briquettes and the resulting preservatives and also the effect of drying and windproof.

When the special non-combustible Fuji of the present invention manufactured in this way is used on a ceiling board, etc., the hygroscopicity and breathability of flour and briquette materials are good, so it is effective to maintain indoor comfort by adjusting the humidity of the room, and it can be sawed and nailed at any place. Depending on the application, it can be used for various purposes such as building materials, albums, book covers, non-combustible boxes, insulation materials, etc., and does not generate toxic gas in case of fire. In addition, the material used in the present invention is extremely economical because of the low cost and easy to purchase, and is an excellent invention in terms of its effect.

Claims (1)

90-110 mesh briquette fine powder and cement are mixed at a ratio of 8: 2, and the mixture is heated and mixed with the nonflammable adhesive by adding flour, formarin and water while maintaining a temperature of 10-20 ° C. A method for producing a special non-combustible fuji, characterized in that the drying process at 70-80% moisture in a drying chamber at 150 ℃ and re-dried at room temperature, compression processing with a temperature control roller.
