示す。Among various heat transfer mechanisms, radiation heat transfer occupies a unique position in that heat is transferred through materials with extremely low thermal conductivity, such as vacuum or air. Since the mechanisms are different, the insulation for radiant heat transfer is exactly the same as that for other heat transfer mechanisms. Heat insulating materials against radiant heat transfer (hereinafter referred to as radiant heat insulating materials) are materials that are difficult to absorb infrared and visible light Mk, and are difficult to emit. Generally, many metals and alloys have this property, but it is a property that deteriorates as the oxide ash layer develops, and those that are resistant to rust exhibit good properties. In particular, silver and aluminum exhibit excellent performance.

費エネルギーが大きい加工法でめる次めコストが高い。Various combinations of metals, which serve as radiant heat insulators, and organic fiber materials, which serve as heat insulators for conductive heat transfer and convection heat transfer, are conventionally known. It is well known that metal foil and cloth are glued together, and cloth is coated with gold, metal powder, synthetic resin, etc. The disadvantages of these methods are that the sheet becomes extremely hard, the heat resistance and lifespan are determined by the resin composition and are often significantly inferior to those made of only N1 cloth, and the breathability and moisture permeability are extremely poor. Plated and steamed on cloth
Methods are known to do this, but the metal films used in this process are generally extremely thin, have low strength and durability, and are expensive due to the long processing time and high energy consumption.

Thermal spray processing is performed by forming a fibrous material into a sheet shape, and further processing to restore the sheet material to its original shape is required. do.

っている。As a highly efficient technique for coating metal materials, etc., the thermal spraying method is known in the past, in which molded products are created by spraying the coated material, which is made of fine particles capable of forming a melting layer, onto a temporarily processed material along with a high-temperature fluid. It is widely used as a surface processing technology for metal molded products.Recently, it has also been used for surface processing of ceramics, etc., but it has low thermal conductivity and heat resistance such as organic fibers. Yoneji was told that heat transfer during processing is difficult for materials with a low temperature, so the heat brought in by the spraying material raises the temperature of the sprayed object, causing deterioration of the fibers and making it difficult to bond properly. In addition, it has been said that if the temperature of the thermal spray fluid is lowered or the thermal spray is performed from a distance in order to avoid this problem, the thermal spray particles will not become integrated and will not bond with the fiber material. To this end, it is a well-established theory that thermal spray materials cannot be processed unless they have a melting point lower than the softening point or thermal decomposition temperature of the fiber material.

Furthermore, JP-A No. 11852-66798 discloses an example in which epoxy resin blend polymer, polyethylene, polypropylene, and nylon 11 are thermally sprayed as thermal spray powder onto vinylon cloth and cotton cloth by thermal spraying using a plasma jet. There is. In all of these examples, the melting point of the organic fiber is higher than the melting point of the thermal spray material, and the maximum temperature of the plasma is around 1000°C, but the actual thermal spraying temperature is higher than that of the thermal spray material. The melting point is also considered to be slightly lower than the thermal decomposition temperature.

きいラミネート加工のほうが概して有利と考えられる。The non-inventor happened to discover that this established theory was wrong while researching thermal spraying technology, and arrived at the present invention. When thermally spraying @, a sprayed coating with weak bonding strength is obtained, but if a thermosetting resin is coated on a hard vinyl chloride plate and copper is sprayed while it is in a semi-cured state, a thermal sprayed coating with strong bonding strength is obtained. It is said that it is obtained. This method is considered to be an advantageous method for joining plastic plates and metal, but for joining cloth foil and metal, the process is slower than laminating cloth foil and metal film. Laminating is generally considered advantageous due to its greater flexibility.

と考えられる。However, it is thought that a new product can be obtained because the intermediate layer gold film, which has better heat resistance and chemical resistance than the thermosetting resin, has a greater protective effect on the organic fibers in the fabric due to the presence of the intermediate layer.

つ之。For example, as an intermediate layer, organic fibers and gold S, which has a slightly lower melting point, can be used.
(Alloy) When using T-, when all metals with high melting point are thermally sprayed,
It exhibits a protective effect by absorbing the heat brought in by the sprayed material using the latent heat of melting. While considering thermal spraying using such an intermediate layer, due to a mistake in experimental operation, gold J!, which has a higher melting point than organic fibers, was added to the part without the intermediate layer. It was found that the peel strength of the Jt-sprayed part was greater than that of the part where the intermediate layer was present, and from this we learned that the conventional theory was wrong.

厚さが不足する場合にはこの操作を反復すればよい。As a result of various studies, the inventors found that by shortening the contact time for one recitation with the high-temperature fluid used for thermal spraying and by cooling it as quickly as possible after contact, it was found that It has been found that by thermal spraying inorganic materials such as metals and ceramics with a melting point much higher than that of the organic fibers, it is possible to obtain filament-like, rope-like, cloth-like, film-like, or thin plate-like fibers. If the thickness of the molded product produced by zero injection is insufficient, this operation may be repeated.

。When thermal spraying is applied to a fibrous structure, the structure is formed into a sheet.Sheet forms include woven fabrics, knitted fabrics, fabrics, paper-like materials, fibers, threads, and nets. , by arranging the ropes in a substantially parallel state, and by compressing them flatly by pressure. (Hereinafter, such a structure will be referred to as a sheet-like product.) The sheet-like product can be used either directly or after completing the commonly used fiber processing process. It is possible to unravel the M4 sheet material and use one piece of steel or the like. It is also a skill to spirally wind a 1fC thread, rope, etc. in parallel, spray it, and then unwind it. You can stretch the net in the direction of the a-eye to make it flat and use it as a sword. It is also possible to thermally spray a sheet-like material, slit it into a tape shape, and heat it or RTGM it to make it into a rope shape. The sheet material can be subjected to various processes that can be applied to ordinary fibrous materials before, after, or simultaneously with thermal spraying.

The speed is 410 m/min or more and the speed of sound is less than or equal to the speed of sound. It is preferable that cooling is also performed from the back side of the sheet-like material. Cooling from the back side is done by co-rotating rollers,
Ridge-shaped plate cooling device yIL7i: It is preferable to use a solid cooling device with a heat removal device provided inside the plate. This is because by densely layering the solid material in a cooling device, it is possible to prevent the sheet-like material from being undulated by the fluid flow for thermal spraying and cooling, resulting in non-uniform thermal spraying.

This appears to be due to the bonding force on the fiber surface and the entangled structure at the interface between the two components. Such a structure can be formed even under conditions where there are considerable discontinuities in a molded article made of gold as a living body, and the presence of such discontinuities results in a structure that is extremely flexible, yet highly durable. A good composite material is formed.

形する。Thermal spray processing of metal materials during the production of the composite material of the present invention involves the formation of fine particles of raw materials at a temperature that can be bath-melted or sintered in the plasma generated by flames, electric discharges, etc. After that, the plasma stream is heated to a high temperature. It is carried by the airflow and is made to collide with the sheet-like object. Then, the relative velocity between the central axis of the sheet-like material and the high-temperature fluid used for bath irradiation is Q, 1 m/sec or more and Loom/sec or less, and the sheet-like material is rapidly cooled immediately after it is separated from the high-temperature fluid. Therefore, the sheet-like material is removed from the high-temperature fluid used for thermal spraying before it deteriorates due to heat. Cooling of the sort can also be added at a stage before contacting the hot fluid. This cooling increases the heat capacity of the sheet-like material and suppresses deterioration. This operation is repeated until the thermal spraying rate reaches a desired value, and the metal material is formed into a film, sponge, or lint-like shape on the sheet material.

スポンジ状の成形物を得ることができる。Particles are a matter of luck! Depending on the amount, it is pressed onto the fiber surface and forms a film, and some of it sticks to the fiber surface and becomes fixed. A part of the particles passes through the gaps between the fibers into the sheet-like material and fuses with subsequent particles to form a network structure. Particles pressed onto the surface of the organic fiber 37' (particles soften and melt near the surface of the organic fiber due to the amount of heat they have, but by cooling this at a sufficient rate, it softens at the core 1 of the fiber. We have found that it is possible to form a metal static spray coating layer without using metal particles.By selecting the spraying conditions, metal particles can be formed into a continuous film, an intermittent film, or an intermittent film.
A sintered body-like molded product or a sponge-like molded product can be obtained by incorporating particles that do not melt during thermal spraying to form a layered film-like material.

どがある。Thermal spraying may be carried out on one side or both sides of the sheet material mainly made of organic fibers. When double-sided, the spray materials can be the same and rarely different. Although it is possible to use only one type of thermal spray material, it is simple and cost-effective; however, in some cases, a sufficient function cannot be obtained with plants, so it is sometimes preferable to use two or more materials. For irradiation of two or more materials, irradiation may be carried out sequentially in a multilayered manner, and by irradiating a mixture near the boundary between two materials, the composition changes from one to the other. It is also possible to form a mold.0 When spraying in multiple layers, it is possible to spray materials with extremely high melting points with high efficiency by sequentially spraying materials with melting points between t''.0 Especially when metal t-sprayed, As the thermal sprayed film becomes thicker, it becomes easier to cool it quickly, and as a result, subsequent thermal spraying tends to be more efficient.Also, when spraying in multiple layers, a layer with high hardness is sprayed in the first layer. Thermal spraying F! Crack in L membrane't1. It is possible to suppress the phenomenon that causes First, a soft metal such as tin or zinc is shot, then a slightly hard gold M4't r& is shot on top of it, and then a hard metal -? By thermally spraying a high melting point metal, cracks n in the thermally sprayed engraving layer can be significantly reduced. Furthermore, when thermal spraying is performed in a multilayered manner, a metal having a high infrared reflectance is sprayed on the outermost layer, thereby making it possible to form a highly effective radiation heat insulating material with a small amount of metal in °C/p. Preferred metals for this purpose include aluminum and silver.

る。In the present invention, the sheet material mainly composed of organic fibers, which is a portion of the composite material of organic fibers and inorganic materials, refers to woven, knitted, nonwoven, braided, paper, etc. of natural and artificial organic fibers. It has a flat shape, and includes those that have been brushed, flocked, flocked, coated with wood, etc. This instep may contain some inorganic fibers, adhesive resins, fillers, adhesives, and various finishing agents. A thermal spray molded product containing a metal or alloy is a thermal spray molded product containing a metal or alloy that can be sprayed and has a melting point higher than the thermal decomposition temperature of the organic fiber as another component. Alternatively, thermal spray moldings containing alloys include metals, alloys, cermets which are composite materials of metal and ceramics, and thermal spray moldings of composites of metal powders or alloy powders and plastics. Since it is difficult to measure the reflectance of a thermally sprayed molded object, it is difficult to measure the reflectance of a thermally sprayed object, so it is measured using a plate made of the same material as the wavelength Q, 7. A material having a reflectance of infrared rays of ca to 20 μm of 80% or more, preferably 90% or more is used.

の生産速度は上らなくなる。As the thermal spraying method according to the present invention, any conventionally known method can be applied. A method in which the entire 11I-shaped thermal spray material is introduced into an electric discharge, crushed, melted, and thermally sprayed is preferable for manufacturing the composite material of the present invention. The relative velocity between the object and the spray gun is 0.1 to Loom even when n.
/ seconds □ Q, l m If it is less than 7 seconds, cooling will be insufficient no matter how you change the spraying conditions.
Deterioration of organic fibers is unavoidable. On the other hand 100
It is difficult to move the thermal spray gun at a speed as low as 100 m7 seconds, and the only viable method is to rotate a cooling roller with a sheet-like material on it at high speed, but if the relative speed exceeds 100 m7 seconds, centrifugal force Thermal spray particles become difficult to solidify. The relative speed between the sheet material and the thermal spray gun is preferably 0.5 to 20 m/sec, and if it is 5 m/sec or less, the metal material to be sprayed and the spraying conditions are severely limited, which is disadvantageous in terms of cost. be. If the speed is 20 m/sec or more, the length that the sheet-like material travels during the speed increase process at startup of the device becomes significantly long, and in order to maintain the uniformity of the sprayed product in this area, the length of the sheet material must be extremely long. ! It is necessary to perform complicated thermal spraying amount control, resulting in a disadvantage that the cost of the apparatus becomes extremely high. The relative speed between the sheet material and the thermal spray gun is more preferably 1 to 5 m/sec. When the speed is 1 m/sec or more, many types of metal materials for thermal spraying can be sprayed under the conditions where the spray gun's performance is maximized, and even if the relative speed is increased by more than will no longer rise.

くくなる点注意を要する。The surface of the spray molded product obtained by the method of the present invention has a highly uneven surface, does not have a strong gloss, and exhibits a so-called uneven appearance. When the thermal spray molding is made of malleable gold, the surface can be easily smoothed. Smoothening of the surface can be achieved by applying strong pressure to a smooth surface. Pressure treatment is preferably carried out between rollers made of a hard material having a smooth surface. Materials that are malleable at temperatures at which the FA fibers do not deteriorate can be selected from metals and alloys. If the material of each layer has m-ductility, it is possible to smoothen a multi-layered molded product. Even in the case of a material that is not malleable, if you first thermally spray a material with a malleable property and smooth it, and then thermally spray it on top of it, the smoothness will improve. Please note that the treatment will cause thermal spraying to occur, making it difficult to spray.
