JP2001200255A - Production method for water-soluble inorganic noncombustible liquid - Google Patents

Abstract

PROBLEM TO BE SOLVED: To produce a noncombustible harmless building material which does not spread fire, though it is carbonized at 600-800 deg.C, by impregnating a building material, such as a floor material, a partition material, a wall material, or a ceiling material, with a water-soluble noncombustible liquid and drying the impregnated material. SOLUTION: When dried, the water-soluble noncombustible liquid leaves behind inorganic chemicals, providing fire resistance. Therefore, though the formulation of the liquid is varied depending on the kinds of building materials and some building materials, such as a curtain material, require a waterproofing treatment, all the material permeable to an aqueous solution can be made fire- resistant. In addition, a liquid which can make polyamides, polyesters, etc., heat-resistant is now under development, and more fire-resistant building materials are expected to be made producible in near future. Thus, many problems with the conventional building materials, such that some building materials spread fire or some flame-retardant building materials generate a chlorine gas, are solved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial application] In addition to making harmless resins such as tetron and nylon heat resistant, building materials are mainly made of inorganic nonflammable liquid at 500 ° C.
Suitable for harmless materials that do not spread even at ~ 800 ° C.

[0002]

2. Description of the Related Art Most of conventional building materials have flame-retardant wallpaper, but most of the floor materials such as tatami mats, carpets, shoji paper, fusuma paper, partition boards, etc. are spread. Things are used. In addition, many flame-retardant wallpapers use PVC, and in the event of a fire, harmful chlorine gas is generated and smoke is killed in many cases.

[0003]

Most of the fires are ignited from the floor, and the wall spreads and burns to the ceiling in many cases. In particular, tatami, shoji paper, fusuma paper, and the like are materials that instantly burn and increase the heat. According to the present invention, these materials are impregnated with a nonflammable liquid and dried to a temperature of 500 ° C. (lighter fire) to 8 ° C.
Even at 00 ° C., it is possible to provide a building material that is locally carbonized but does not spread fire and that does not generate any harmful gas.

[0004]

The main building materials that burn on the floor are tatami mats, carpets and the like. In the case of tatami mats, this type of building material burns on a straw bed due to cigarette fire or the like.
When impregnated and dried, it becomes a non-combustible material at 500 to 600 ° C. Even if a cigarette is put on the surface of the rush and burns, half of the surface rush will carbonize and the back will not carbonize and will not carbonize to the straw bed. Carpets have a similar effect.

[0005] Next, curtains and wall paper, which are wall materials, need to be further waterproofed after being impregnated and dried with a noncombustible liquid A for washing in order to be washed. Furthermore, in the case of wallpaper, instead of using PVC as a conventional surface material, a woven or nonwoven fabric and a nonwoven paper are impregnated and dried with a nonflammable liquid containing a nonflammable liquid A and a nonflammable liquid B appropriately. The back paper is impregnated with the noncombustible liquid A to make a noncombustible material. As a noncombustible adhesive between the front noncombustible material and the back noncombustible material, sodium silicate 70% to 90%, kaolin 1.5% to 5.0% , Iron oxide 0.5% to 3.0
%, Silicone is 1.5% to 3.0% by weight and a non-combustible adhesive is used.
It becomes a non-combustible wall material and a non-combustible ceiling wall material that does not spread even at 00 ° C. and does not generate any toxic gas.

[0006] The non-combustible ceiling wall material is made of the above-mentioned inorganic non-combustible wall, and the main raw material is a fine pearlite foamed 20 times as a ceiling plate, mixed with sodium silicate, silicone oil and reinforcing fibers, and press-molded. A fireproof ceiling material of 800 ° C. or higher can be obtained by attaching a perlite fiberboard.

[0007]

The nonflammable liquid of the present invention is composed of inorganic and harmless building materials from the floor surface to the side walls and ceiling materials.
Since it is a building material that carbonizes at 00 ° C but does not spread and does not generate any toxic gas, it is much more suitable for a house with a fireproof construction than conventional building materials. Next, Table 1 shows the carbonization ratio (carbonization length) of the compounding ratio (weight ratio) of the nonflammable liquid of the present invention. Test method (A) Test product 1. Shoji paper (Sample 1 to Sample 4) Wallpaper Japanese paper + non-combustible adhesive + shoji paper (sample 5 to sample 6) (B) Burning method Cut to 2 cm wide and 15 cm long and ignite for 5 minutes on a lighter fire (460 ° C) as shown below.
