More specifically, the present invention relates to precision equipment parts such as printed circuit boards such as copper-clad laminates, flexible printed boards, multilayer boards, IC cards, liquid crystal display boards, ceramic laminates (hereinafter referred to as "in the present invention The present invention relates to a cushioning material for hot pressing used in press molding or thermocompression bonding of a target product in a process of producing a laminated sheet) and a method of manufacturing the same.
- a laminate material 12 to be pressed is a heating plate 13 as a heating / pressing means, A method of sandwiching between 13 and applying constant pressure and heat is used.
- the heat pressing is performed in a state in which the flat cushion member 11 is interposed between the hot platen 13 and the laminate material 12.
- a cushioning property that absorbs the unevenness of the hot platen 13 and the laminated board material 12 a laminated board material 12 from the hot platen 13 over the entire press surface 12 In-plane uniformity to uniformly transfer temperature and pressure, heat transferability to efficiently transfer heat from the hot platen 13 to the laminate material 12, and heat resistance that can withstand the press temperature.
- the cushioning material 11 for hot press a paper made of approximately 3 to 20 layers of kraft paper or linter paper is often used.
- the cushioning material made of paper has balance /! Physical properties in terms of cushioning, in-plane uniformity and heat transferability! This is because a suitable void contained in the paper acts on the cushioning property, and the fact that the constituent fibers of the paper are oriented substantially in the planar direction affects the in-plane uniformity, and the thickness per sheet is It is thought that a thin thickness of about 0.
- the cushioning material made of paper while being strong, has no restorative force in the air gap after pressing, and it is further composed of fiber
- it has the disadvantage that it can not be used repeatedly for multiple presses because it is thermally degraded.
- cushioning materials for hot press that can be used repeatedly
- various types of materials such as those obtained by bonding organic or inorganic fibers with a binder, rubber, non-woven fabric, woven fabric, and laminates thereof. It is done.

For this reason, the cushioning pad for a heat press using a needle punched non-woven fabric has a disadvantage that the in-plane uniformity for uniformly transmitting temperature and pressure is deteriorated. In addition, the needle punched non-woven fabric can not be made much thinner because it is necessary to entangle the fibers by needling the web in the thickness direction. For example, in the cushioning pad for hot pressing described in the above-mentioned publication, since the thickness is finally about 3.3 mm to 3.7 mm, there is a disadvantage that the heat conductivity also becomes worse.
- the cushioning material for hot press described in the above-mentioned publication is subjected to heat and pressure treatment after the needle-punched non-woven fabric is impregnated with the heat resistant resin, the porosity becomes small and the durability is also very good.

Because it maintains a certain degree of porosity, it exerts a good cushioning property. Furthermore, since the bulky yarn is woven and takes the shape of a woven fabric, the fabric weight accuracy is better compared to the non-woven fabric, and the in-plane uniformity is excellent. In addition, since it takes the shape of a woven fabric, the thickness can be smaller than that of the non-woven fabric, and the heat transfer property can be excellent.

That is, the heat and pressure applied to the laminate material 12 as the object to be pressed by hot pressing in a state in which the cushioning material 11 for hot press is interposed between the hot platen 13 and the laminate material 12 are It can be made uniform over the entire surface.
- a glass woven fabric "T860" manufactured by Unichika Co., Ltd.
- This woven fabric is a bulky yarn obtained by bulk-processing double-twisted yarn having a count of 305 te X consisting of 3200 wefts of glass fiber (fiber diameter 6 m), consisting of 1600 warp glass fibers (fiber system 6 am) It is a double-twisted yarn with a bulk of 135 tex, which is not bulk-processed, and is formed by weaving a warp yarn and a weft yarn into a double weave.
- This woven fabric has a weight of 850 g / m 2 , a thickness of 1.02 mm and a porosity of 67%.
- an unvulcanized fluoro rubber solution was prepared by dissolving unvulcanized fluoro rubber at a predetermined concentration in a solvent in which butyl acetate and methyl ethyl ketone were mixed at a mass ratio of 1: 1.
- the solid content ratio of each unvulcanized fluororubber solution was as shown in Table 1. After immersing glass woven fabric in each unvulcanized fluoro rubber solution, two rolls each Squeezed. Next, each glass woven fabric impregnated with the unvulcanized fluororubber solution was sufficiently dried to remove the solvent.
- Sample 10 is the same cushioning material for hot pressing as sample 2 except that a normal woven fabric not using bulky yarn is used as the glass woven fabric. That is, as a woven fabric, a glass fiber woven into a twill weave using a bulk yarn of 405 tex with a count of 405 tex consisting of 2400 glass fibers (fiber system 9 II m) and using synthetic yarns as warp yarns and weft yarns. " A710 " (manufactured by Unichika Co., Ltd.) was used. This woven fabric has a weight of 708 g / m 2 , a thickness of 0.60 mm and a porosity of 5 3.5%.
- a solution was prepared by dissolving 14.2% solids of unvulcanized fluororubber in a solvent in which butyl acetate and methyl ethyl ketone were mixed at a mass ratio of 1: 1.
- the glass woven fabric was immersed in an unvulcanized fluororubber solution, squeezed with two rolls, and then sufficiently dried.
- the same surface layer material as sample 2 was laminated and integrated on the upper and lower surfaces of the non-vulcanized fluororubber-impregnated glass woven fabric in the same manner as sample 2, and the fiber rubber composite material and the surface layer were integrally laminated.
- the cushioning material for heat press of structure was obtained.
- the sample 11 used the needle punch nonwoven fabric which consists of a web of meta-based aromatic polyamide fiber "Corex" (made by Teijin Ltd.) of 2 d in thickness and 51 mm in fiber length.
- This non-woven fabric was prepared by laminating the above-mentioned web on both sides of an adhesive base fabric obtained by applying unvulcanized fluororubber to an open glass cloth and subjecting it to needle punching.
- the non-woven fabric had a weight of 350 g / m 2 , a thickness of 2. O mm, and a porosity of 87.3%.
