[Industrial Field of Application] The present invention relates to a sheet material that is nonflammable or highly flame retardant, and has excellent stain resistance and weather resistance. [Prior Art] In recent years, sheet materials containing various synthetic resins have been used as building materials, interior materials, and members of vehicles, ships, aircraft, and the like. These synthetic resins have the disadvantage of generating a large amount of noxious or toxic gas or smoke when burned in a fire or the like. For example, a large amount of sheet materials containing polyvinyl chloride resin are used as the above-mentioned sheet materials, and various proposals have been made to make such sheet materials nonflammable or flame retardant. For example, Japanese Patent Publication No. 55-4852 proposes adding a borate, a zinc compound, or an iron compound, and aluminum hydroxide or barium sulfate to the polyvinyl chloride resin to be applied to the sheet material base fabric. However, the results are still not completely satisfactory. Japanese Patent Publications No. 53-13505, Japanese Patent Publication No. 51-37397, and Japanese Patent Application Laid-Open No. 54-68470 propose the use of silicone resins as nonflammable resins. In these cases, the effect of making it nonflammable or flame retardant is quite high, but when sheet materials coated with such silicone resins are used outdoors, for example as sheets for tents, they can deteriorate significantly during use. This silicone resin coating layer is easily stained and has a soft and brittle surface, so that it has the drawback that various solid dust particles may adhere to it, enter it and become buried therein, or the coating layer may peel off. Therefore, a non-combustible tent membrane material, which is a glass fiber base fabric coated with PTFE (polytetrafluoroethylene), has recently been developed and used. However,
PTFE is difficult to form into a film, so for example, a dispersion with a concentration of 60% and a viscosity of 20 centipoise is immersed in high temperature (approximately 400℃ or even
It is manufactured by firing coating at 350℃~500℃). Since such immersion and high-temperature firing are performed, the processing speed is slow at approximately 30 cm/min, and if a sufficient coating thickness is formed at once, sagging, muddy cracks, and foaming may occur on the coated surface, resulting in cracks in the coating. There are also disadvantages in terms of performance, such as the occurrence of problems, and there are also problems in processing since this operation is repeated two or more times. In addition, since high temperatures are applied during processing, the strength of the noncombustible sheet material is also reduced, and the adhesive strength is also unfavorable. In addition, in Special Publication No. 58-36111, fired PT
A copolymer resin film of tetrafluoroethylene and perfluoroalkyl vinyl ether or a copolymer resin film of tetrafluoroethylene and hexafluoropropylene is superimposed on a thin FE resin plate, and this is heated at a temperature of 327°C or higher. It is disclosed that the laminate is melted and laminated at an extremely high temperature, and the laminate is bonded to an inorganic fiber woven fabric by heating and pressurizing at a temperature of 305°C to 315°C to form an inorganic fiber woven fabric-fluororesin composite. has been done. However, since PTFE thin plates are used in this composite,
The product was a plate-like product that lacked flexibility and could not be used as a flexible sheet. In addition, since PTFE with a high melting point is used, high temperatures of 327°C or higher are required even when bonding with the copolymer resin membrane.
For this reason, there is a problem that the performance of the copolymer resin film is deteriorated and the durability of the final product is therefore insufficient. Furthermore, there was also the problem that the lamination process was complicated. [Problems to be Solved by the Invention] The present inventors have studied ways to eliminate these drawbacks of the conventional techniques, and have developed a method in which a fluorine-based resin film having a melting point of 280°C or lower is first formed, and then By melting and attaching it to a non-flammable base fabric, the disadvantages of conventional technology, especially when using PTFE, can be overcome.
found it to be effective. As a result of further consideration,
In order to maintain adhesive strength (peel strength) and strength,
In particular, in order to reduce the deterioration of the base fabric due to high-temperature heating and maintain its strength, the melting point of the fluororesin film must be lowered.
If the temperature is selected to be 280°C or lower, preferably 250°C or lower, and the treatment temperature is set to 300°C or lower, preferably 270°C or lower, there will be no decrease in the strength of the non-flammable base fabric, such as glass base fabric, and no deterioration of the film. In addition, the present invention was completed based on the discovery that, particularly in the case of attachment via an adhesive substance, a sufficient and preferable adhesive force can be provided without reducing the effect of the adhesive substance. [Means for Solving the Problems] According to the present invention, there is provided a nonflammable sheet that solves the above problems, and this sheet comprises a nonflammable base fabric made of nonflammable fiber fabric, and at least one surface thereof. A fluorine-based resin film layer having a melting point of 280° C. or lower is melt-bonded thereon. In addition, in the method for producing a nonflammable sheet of the present invention, fluorine having a melting point of 280° C. or less is added to at least one surface of a noncombustible base fabric made of a nonflammable fiber fabric and coated with an adhesive substance or not coated with an adhesive substance. melting at least the adhesive surface of the based resin film,
It is characterized by being bonded together at a temperature of 300°C or less. To further explain the present invention in detail, the non-flammable base fabric used in the sheet material of the present invention is made of non-flammable fiber fabric, and examples of such fabric include glass fiber, asbestos fiber, metal fiber and/or non-flammable fiber fabric. Alternatively, knitted fabrics or nonwoven fabrics made of other inorganic flame-retardant fibers, such as carbon fibers, can be used. The glass fiber fabric for the base fabric preferably has a loss on incineration of 1.5% or less and a cross cover factor of 25 to 35, in order to have good adhesion with the coating layer, flexibility, water resistance, etc. 50Kg/25mm
or more, especially longitudinal and latitudinal tensile strength of 200Kg/25mm or more, and 100g/m2 or more, especially 200 to 900g/
Those having a basis weight of m 2 are preferable. There are no particular limitations on the type of glass fiber or the thickness of the single fibers, but in general, beta yarns with a thickness of about 2 to 10 μm, particularly about 3 μm, are used. A fluorine-based resin may be attached to the fiber surface of such a base fabric. Moreover, such a base fabric may be one obtained by impregnating a nonflammable fiber fabric with a fluorine-based resin liquid, drying it, and then firing it. The fluorine-based resin used in the present invention may be any resin as long as it has film-forming properties, has a melting point of 280°C or less, and can be hot-melted. For example, FEP (tetrafluoroethylene-hexane) can be used. Fluoropupylene copolymer

The present invention has the above-mentioned structure, and provides a nonflammable sheet that fully utilizes the weather resistance, antifouling, and flame retardant properties of fluorine-based resin, and also allows for the production of these sheets without the conventional methods. Unlike the PTFE coating method, there is no pollution caused by decomposed gas or unproductiveness due to processing speed, and there are no problems such as dripping of processing agents, muddy cracks, or foaming, and the resulting film is homogeneous, which is more preferable. A nonflammable sheet can be easily obtained. In addition, by selecting the processing conditions, it is possible to obtain a more preferable durable film agent, and by further selecting the laminated structure, it is possible to obtain a nearly perfect non-combustible film agent.The practical value of the sheet of the present invention is extremely high.
