Abstract

PROBLEM TO BE SOLVED: To improve heat resistance, light-weight, soft viscosity, strength and heat conductivity by impregnating a coat with a fire resisting solvent. SOLUTION: In the case where a coat has a heat resisting temperature of 600 deg.C, paper is impregnated with a fire resisting solvent having such a weight distribution ratio that borax 1.3-1.5%, ammonium sulfamate 10-15%, and hot water 82-87% without salt or iron and dried to be used. To make this paper into a coat which is not carbonized even at 1000 deg.C, a wetting agent of a complex is used where a hydrogen compound with a specific gravity of 1.3 of silicone and hydrogen. In the case of taking fibrous paper or paper mixed with cotten as a fire resisting coat 2 to 1000 deg.C, the coat is impregnated with the solvent, and then dried. In the case of taking resin as a coat, a solvent is mixed in the resin and made into a thin film to be bonded to fire resisting paper. The coat 2 has tensile strength, bending strength and light-weighted soft viscosity. The solvent is colorless, odorless and not hazardous to the skin and clothes, and has no carcinogenesis, and even if spreading fire if caused, dioxins is not generated.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a heat generating structure used for bedding, rugs and the like.

[0002]

2. Description of the Related Art In many cases, an insulating sheath of a flexible heating element is mainly formed by laminating a PVC film, a polyester film, or the like. They degrade at 80-120 ° C., dissolve or crack, carbonize and then ignite. Normally, when this kind of heating element is used for bedding or rugs, it is controlled using a heat sensing wire or temperature fuse that detects abnormal temperature, but it does not sense when there is a local muffled temperature, In this case, the temperature is 100 ° C. or higher. If this state continues many times, the outer skin is carbonized together with the deterioration of the resistor, eventually causing ignition. Next, when the above-mentioned outer skin is heavy and made into a product, it is not effective because elderly people have difficulty carrying.

[0003]

In order to solve the above-mentioned problems, it is appropriate to use inexpensive paper as a skin having nonflammability, waterproofness, soft viscosity and light weight. Some of the paper itself has strength, and other methods of imparting strength to the outer skin include the use of woven cotton or a small amount of resin, which can be adapted according to the purpose of use.

[0004]

Means for Solving the Problems When the outer skin is about 600 ° C., a refractory solvent having a weight distribution ratio of 1.3 to 1.5% borax 10 to 15% ammonium sulfamate 82 to 87% of warm water free of salt or iron What has been impregnated and dried on paper is sufficient. However, a composite wetting agent mixed with a hydrogen compound having a specific gravity of silicon and hydrogen of 1.3 is used to make the skin not carbonized even at 1000 ° C. Since the complex is water-soluble and is decomposable, its effect can be maintained even at a dilution of about 4000 per 1 of the complex. This kind of liquid can be applied to any material such as wood, chemical oils and fats, and can be used for non-combustible paper or non-combustible wallpaper and non-combustible plate.

[0005]

The PVC sheet has a disadvantage that it changes when the temperature becomes 50 ° C. or higher because a plasticizer is used. Further, when the heating element is discarded and burned, dioxin and the like are generated. The mixture of silicon and hydrogen used in the present invention is colorless, odorless, has no danger to the skin and clothing, has no carcinogenicity, has durability, and does not generate dioxin even when fire spreads. By impregnating the paper with this solution, it is possible to cope with a temperature of 1000 ° C.
Therefore, the non-combustible paper having thermal conductivity is sensed by the surrounding heat-sensitive wire just before the carbon heating element deteriorates and the spread of the heating element is prevented.

Reference numeral 2 denotes an outer cover made mainly of paper having the noncombustibility, waterproofness, soft viscosity and light weight of the present invention.
In the case of fibrous paper or paper mixed with cotton, the fireproof waterproof solvent is squeezed by the method of impregnating the entire surface of the solvent and then dried.
It can be made into a thin film and adhered to fireproof paper. The outer skin thus formed is a revolutionary lightweight and viscous fire-resistant outer skin that has a tensile strength and can cope with bending and the like.

[0007]

The present invention impregnates the outer skin (mainly using paper) with a refractory solvent that can withstand 1000 ° C., so that not only heat resistance but also light weight, soft viscosity and good strength and heat conduction are obtained. Due to the deterioration of the heat-generating part, it has the characteristic that the heat is detected by another heat-sensitive wire just before ignition and the power is cut off. Furthermore, when incinerated harmlessly, carbonization is performed at a high heat of 1000 ° C. or more, and the generation of dioxin and the like can be prevented in a small amount, which is far more effective than that using a PVC sheet.
