Description of the Invention: [Technical Field] The present invention relates to a surface layer for a cushioning material for hot pressing and a cushioning material for hot pressing, and in particular, to manufacture a copper laminated plate and to be flexible In the steps of a printed circuit board such as a printed circuit board or a multilayer board, or a precision machine component such as an ic card, a liquid crystal display panel, or a ceramic laminate (hereinafter referred to as "layered board" in the present invention), The cushioning material for hot pressing and the surface material for cushioning materials used for press molding or thermocompression bonding of the target product. [Prior Art] In the manufacturing step of the laminated board, first, the laminated board material as a material is superposed to prepare a compressed body. Then, after the compressed body is placed between the hot plates, hot pressing is performed, that is, heat pressing is performed by pressing, and the thermoplastic resin or the thermosetting resin contained in the laminated board material is flowed. Harden and make it one. In the step of performing the heating and pressurization, when the heated plate or the compressed body belonging to the input member is inferior in thickness, thermal deformation, temperature unevenness, etc., the compressed body which later becomes the product cannot be subjected to the uniform temperature. Pressure: If 'there will be defects in the product's thickness, 'breaking, warping and other defects. In order to eliminate defects such as poor thickness of the product, the use of a cushioning material for hot pressing (hereinafter, also referred to as "the heating plate that is contacted by 323195 4 201249645 8 has good peelability, etc. - In addition to the cushioning material of the cushioning material, the surface material for the cushioning material is used on the surface of the material (the following is simply referred to as "surface material"). A technique of the present invention is disclosed in Japanese Laid-Open Patent Publication No. 2004-344962 (Patent Document 1) and Japanese Patent No. 3221978 (Patent Document 2). The sheet for hot pressing of the patent document 1 is a sheet material for a cushioning material, which comprises a sheet-like base material and a release coating film formed on the base material. Further, the coating film is composed of 100% by mass of the resin composition. It is prepared by mixing a resin composition of 5 to 55% by mass of the organic powder and 5 to 55% by mass of the inorganic powder to a total of 3 to 60% by mass. With this constitution, it is possible to prevent the surface layer from being formed on the surface layer. The mold-coated film is cratered or dent. In Patent Document 2', from the viewpoint of improving heat resistance, it is disclosed on both sides of a sheet-like substrate made of a heat-resistant material. The unvulcanized fluororubber is coated, and The heat-resistant sexy thermal bonding sheet which is formed by applying a heat-resistant coating material on one side to form a cushioning material for hot press forming, that is, a surface material for a cushioning material. Further, there are also parts having a melamine cloth on the surface layer. The heat-pressing cushioning material, that is, the structure in which the melamine cloth is disposed on the surface layer of the cushioning sheet member. [Prior Art Document] [Patent Document] [Patent Document 1] JP-A-2004-344962 [Patent Document 2] Japanese Patent No. 3221978 5 323195 201249645 [Problem to be Solved by the Invention] In the surface material for a cushioning material of Patent Document 1 and Patent Document 2, the surface of the surface layer itself is relatively hard. Therefore, at the time of pressing, when a dirt (so-called foreign matter) is sandwiched between the cushioning material and the compressed body or the heating plate, the cushioning material having the surface layer cannot be absorbed due to the influence of foreign matter. In other words, the unevenness of the surface of the cushioning material is insufficient. Thus, when a foreign matter is poured between the cushioning material and the compressed body or the heating plate, it is made by hot pressing. The product will reflect the unevenness and cause defects in the product. From this point of view, in the case of the cushioning material, a high degree of bump followability is required to absorb the fine unevenness caused by the foreign matter. In particular, in the case of the recent cushioning material, a cushioning material which is required to have both a thinner wall and a high degree of unevenness has been required. Further, it is disclosed in Patent Document 1 and Patent Document 2 having a surface layer. In the buffer village, the cushioning material has a relatively low softness. Therefore, for example, during the treatment of the cushioning material, there is a concern that cracks, wrinkles, and cracks occur in the cushioning material. Specifically, a cushioning material used for hot pressing for general production of laminated sheets has a dimensional coefficient mx of several m. In the case of such a cushioning material, in the state in which the end portion is lifted from the partial portion, the cushioning material is drooped due to its own weight, or cracks or wrinkles or cracks occur in one of the cushioning members. From this point of view, it is required to have a cushioning material which is highly flexible and easy to handle or handle. Further, in the case where the aforementioned lysine cloth is used as a cushioning material for the surface layer, fuzzing occurs on the surface thereof due to repeated use. The fuzzing will be 6 S 323195 201249645 as a cause of dirt, and therefore, there is a requirement to reduce the occurrence of fuzzing. In particular, recently, a material such as a polyimide resin has been used as a material for a laminated board, and hot pressing at a relatively high temperature is carried out, specifically, for example, hot pressing at 200 ° C or higher. In such high-temperature hot pressing, the deterioration of the fibers of the melamine cloth is particularly remarkable, and the occurrence of fuzzing often occurs. Further, in the case where melamine cloth is used as the surface layer, the surface thereof is hardened due to deterioration after use, and the above-mentioned unevenness followability is deteriorated. It is an object of the present invention to provide a surface layer for a cushioning material which is excellent in unevenness and has a reduced incidence of cracks, wrinkles and cracks. Another object of the present invention is to provide a cushioning material for hot pressing which is excellent in unevenness followability and which can reduce cracks, wrinkles, and cracks. [Means for Solving the Problem] The inventors of the present invention paid attention to the cushioning material body belonging to the inner layer of the cushioning material. Not only the cushioning property but also the surface layer material for the cushioning material disposed on the surface of the cushioning material can be provided with cushioning properties. Of course, from the viewpoint of the above, the surface material for a cushioning material is excellent in not only the occurrence of fluffing but also the peeling property, and the adhesion of the main body of the cushioning material belonging to the inner layer. The surface layer material for a cushioning material of the present invention is a surface layer material for a sheet-shaped cushioning material which is disposed on the surface layer of the heat-shrinkable cushioning material, and includes a resin layer which is disposed on one surface side of the surface layer material and covers one surface of the surface layer material. The other side of the topsheet is covered with a rubber layer on the other side of the topsheet; and a woven fabric layer disposed between the resin layer and the rubber layer and using at least one of the warp yarn and the weft yarn to use the spun yarn. Further, the woven fabric layer comprises: a woven fabric-resin composite layer formed on the resin layer side, 7 323195 201249645 and impregnated with a resin constituting the resin layer in one portion of the woven fabric; and disposed on the rubber layer side, and One of the woven fabrics is impregnated with a woven fabric-rubber composite layer formed of rubber constituting the rubber layer. Moreover, a gap is provided inside the woven layer. The surface layer material of the present invention is a woven fabric layer using at least one of a warp yarn and a weft yarn as a woven fabric yarn. Such a spun yarn yarn y is a yarn in which the short fibers constituting the glass ray are not in parallel with each other, but are entangled in a state of being entangled and turbulent and occupying a large area. In other words, the spun yarn has the swelling property of the yarn, and therefore, the woven fabric using the spun yarn is different from the usual cloth, and contains many voids inside. Then, in the woven-resin composite layer, the resin impregnated into the woven fabric enters into the voids of the voids and textures of the random yarn, and does not completely block the voids, but can maintain a certain degree. Void. Weaving - rubber composite layer 'also (four) ground' impregnated with the woven fabric, the rubber age moderately enters into the gap between the gap and the weaving yarn, and does not completely block the work gap' while i maintains a certain The degree of voiding. Such a void is almost covered by resin or rubber around it, and therefore, even if pressure is applied to press it to 'repress, the recovery force to return it to its original shape is still strong. In other words, the surface layer for such a cushioning material has a gap in the inside of the woven fabric layer disposed between the resin layer disposed on one side and the rubber layer disposed on the other side. J is excellent in the followability of the unevenness, and at the same time, the softness can be improved. In this way, even if there is a tiny foreign matter between the cushioning material and the compressed body or the added, the, and the plate, it can be absorbed due to the foreign matter.

323195 S 201249645 而造成凹凸之影響。因此，可以減少凹凸對於製品之影響。 此外’因柔軟性甚高，因此，可以減低裂縫或皺紋、破裂 之發生。此外，此種緩衝材用表層材，係由樹脂層構成其 一面側，因此，可以減低起毛之發生’同時，可以提高對 於加熱板等之剝離性。此外，另一面側係由橡膠層而構成， 因此’可以提高表層材對於缓衝材本體之接著性。 就織布層而言’雖在構成織布之經紗和緯紗中任一方 使用亂纖紗，但是，當然可以在兩方皆使巧亂纖紗。在經 紗和緯紗中之任一方為亂纖紗時，另一方則可以藉由通常 之單紗或合樵紗來構成。此外，作為亂纖紗之種類，可以 列舉胖纖紗（bulked yarn)、短纖紗（staple yarn)、碎纖 紗（sliver yarn)等。胖纖紗係藉由空氣喷射等而加工成為 膨鬆之紗。短纖紗係由綿狀之玻璃短纖維紡成紗狀。短纖 紗係由綿狀之玻璃短纖維紡成為紗狀。係在未捻撚之膨鬆 碎纖維（sliver)施以捻樵而製成之紗。 此外’織布層相對於作為基材之織布之空隙殘留率係 7〇%以上。就織布層而言，可以藉由設成此種空隙殘留率， 而更加確實地確保凹凸追隨性和高度柔軟性。 在此，就空隙殘留率進行說明。首先，算出作為基材 之織布、也就是在未含浸樹脂和橡膠之狀態下之織布之空 =率。空隙率’首先係以織布之厚度乘以面積來作為織布 整體之體積’由單位面積重量和亂纖紗之比重而算出亂纖 紗之體積，由織布整體之體積扣除亂纖紗之體積，來算出 空隙之體積。接著，算出空隙之體積相對於織布整體之體 323195 9 201249645 積之比率，來算出空隙率。就空隙 用橡膠和樹脂之比重算出含浸有樹脂和橡^織布=使 率。接著，以含浸有樹脂和橡膠之織布 率 = 含浸樹脂和橡膠之織布之空隙率▲料相對於未 說，空隙殘留率係表示相對於未含浸樹= 殘留有多少。 樹月日和橡膠之織布之空隙 作為樹脂，最好是對於前述之熱壓製所造成之熱 耐受性之耐熱性樹脂。具體地說，作為—例，可以使用、 熱性樹脂之熔點和玻璃轉移溫度之至少任_方為侧1以 上之樹脂。就熱壓製而言，在最近，係要求以高溫進行户 理。例如，S 了提高所製造之製品之賴性，即使是用= 構成製品之樹脂，也使用具有耐熱性之樹脂。因此，即使 是緩衝材用表層材，也要求可以承受2〇〇。(：溫度之樹脂。 也就是說，如果是熔點和玻璃轉移溫度中之至少任一^為 2 0 〇 °c以上的話，則製品係由耐熱性樹脂而構成，即使是在 同溫，例如200°C程度之溫度進行熱壓製，也可以作為緩 衝材用表層材而具備耐用性。當然，熔點和玻璃轉移溫度 之兩者亦可以是2〇(TC以上。 作為樹脂’最佳是由例如氟樹脂、苯酚樹脂、三聚氰 胺樹脂、環氧樹脂、不飽和聚酯樹脂、矽酮樹脂、聚醯亞 胺樹脂、熱硬化性丙烯酸樹脂、呋喃樹脂、尿素樹脂、苯 甲酸一埽丙醋樹脂、聚胺基甲酸乙醋樹脂組成之群組中 選出之1種樹脂或2種以上樹脂之混合物。特別是耐熱性 323195323195 S 201249645 caused by the unevenness. Therefore, the influence of the unevenness on the product can be reduced. In addition, because of its high flexibility, cracks, wrinkles, and cracks can be reduced. Further, since the surface layer for a cushioning material is formed on one surface side of the resin layer, the occurrence of fuzzing can be reduced, and the peeling property against the heating plate or the like can be improved. Further, the other side is formed of a rubber layer, so that the adhesion of the surface layer to the cushion body can be improved. In the case of the woven fabric layer, although any of the warp yarns and the weft yarns constituting the woven fabric is used, it is a matter of course that the yarn can be woven on both sides. When either one of the warp yarn and the weft yarn is a spun yarn, the other one may be constituted by a usual single yarn or a twisted yarn. Further, examples of the type of the spun yarn include a bulked yarn, a staple yarn, a sliver yarn, and the like. The fat fiber yarn is processed into a bulky yarn by air jet or the like. The spun yarn is spun into a yarn shape from a short glass fiber. The staple fiber yarn is spun into a yarn-like shape from a short glass fiber. A yarn made by applying a sputum to an unswelled bulky sliver. Further, the void ratio of the woven fabric layer to the woven fabric as the substrate is 7% by weight or more. In the woven fabric layer, by setting such a void residual ratio, it is possible to more reliably ensure the unevenness followability and the high flexibility. Here, the void residual ratio will be described. First, the woven fabric as a substrate, that is, the void ratio of the woven fabric in a state where the resin and the rubber were not impregnated were calculated. The void ratio 'firstly multiplies the thickness of the woven fabric by the area as the volume of the entire woven fabric'. The volume of the crepe yarn is calculated from the weight per unit area and the specific gravity of the crepe yarn, and the volume of the woven fabric is deducted from the volume of the woven fabric. Volume, to calculate the volume of the gap. Next, the ratio of the volume of the void to the volume of the whole body of the woven fabric 323195 9 201249645 was calculated to calculate the void ratio. In the case of voids, the impregnated resin and the rubber woven fabric were calculated using the specific gravity of the rubber and the resin. Next, the ratio of the woven fabric impregnated with the resin and the rubber = the void ratio of the woven fabric impregnated with the resin and the rubber ▲ is relative to the unfilled tree = the residual amount. The gap between the tree and the rubber weave as the resin is preferably a heat resistant resin which is resistant to the heat of the aforementioned hot pressing. Specifically, as an example, at least one of the melting point of the thermal resin and the glass transition temperature may be used as the resin of the side 1 or more. In terms of hot pressing, recently, it has been required to carry out households at high temperatures. For example, S improves the durability of the manufactured product, and even if it is a resin constituting the product, a resin having heat resistance is used. Therefore, even for the surface material for cushioning materials, it is required to withstand 2 turns. (: resin of temperature. That is, if at least one of the melting point and the glass transition temperature is 20 〇 °c or more, the product is composed of a heat resistant resin, even at the same temperature, for example, 200 The temperature can be hot pressed at a temperature of °C, and it can also be used as a surface material for a cushioning material. Of course, both the melting point and the glass transition temperature may be 2 〇 (TC or more. The resin is preferably made of, for example, fluorine. Resin, phenol resin, melamine resin, epoxy resin, unsaturated polyester resin, fluorenone resin, polyimide resin, thermosetting acrylic resin, furan resin, urea resin, benzoic acid propylene glycol resin, polyamine a resin selected from the group consisting of ethyl acetal resin or a mixture of two or more resins, particularly heat resistance 323195

Such a void 2 几乎 is almost entirely retained by the voids originally formed by the random woven yarn 16 constituting the woven fabric layer 14 as a base material. As far as the void is concerned, it is almost entirely covered with resin or rubber. Therefore, even if the pressure applied to flatten it is reduced, the original shape is restored, and the recovery force is strong. Next, the manufacturing method of the surface layer 11a will be described as simple. First, the sheet-like woven fabric of the aforementioned configuration was prepared. Next, the surface of one side of the sheet-like woven fabric is impregnated with a resin. At this time, in order to make the resin easily impregnated into the woven fabric, the resin may be dissolved in a solvent or a varnish may be used. Further, an inorganic powder having conductivity can be added to the resin in advance. In the case of impregnation, a resin layer is formed on the surface of one side of the woven fabric, and the resin is impregnated so that the tree t does not penetrate to the surface on the other side. In other words, the resin layer is exposed on one side, and the other side is impregnated so that the woven fabric woven fabric is exposed. In this manner, a resin layer and a woven-resin composite layer are first formed. Then, calcination is carried out to volatilize the solvent to cure the resin layer and the woven-resin composite layer. Next, the rubber is impregnated from the other side. In this case, a rubber layer is formed on the other side of the woven fabric so as to be impregnated in the thickness direction of the woven fabric. Specifically, impregnation is carried out, for example, by coating a low-viscosity unsulphurized rubber with the other side. Then, the predetermined time is dried. The surface layer of the present invention can be produced in this manner. At this time, it is possible to consider the degree of impregnation 'specifically' such as varnish-like resin dot or impregnation time, impregnation temperature, coating state of unsulfurized fluororubber, and weaving state of woven fabric of woven fabric 323195 15 201249645 Etc., and adjust the residue to the weaving, degree, that is, the residual void ratio.
