Japanese Patent Application No. 296929 (1988) filed on the 4th) [Problems to be Solved by the Invention] In the conventional laminated molded article by die vulcanization, (a) influence of metal fittings on the laminated molded article To reduce as much as possible. (B) Make the laminated compact compact. For this reason, as shown in FIG. 5, metal fittings to be attached to the laminated molded body had flat surfaces with only a few protrusions. When wrapping and vulcanizing a cloth around the laminated molded body having the above structure, the cloth cannot be completely wrapped around the boundary between the metal fittings and the rubber. There was a drawback that the rubber at the boundary portion of No. 1 was not applied with pressure and foamed to deteriorate the physical properties of the laminated molded body and cause insufficient adhesion between the rubber layer and the metal fitting. Further, when vulcanizing the dies one by one, there is also a problem that a large amount of cost is required for preparing the dies. [0004] Further, as shown in [Fig. 6], in the case of a hose or a flexible tube which is currently wound and vulcanized by cloth winding, (i) there is not much restriction on the length. (Ii) The cost does not change much even if it is lengthened. (Iii) The adhesive surface does not peel off even if it is deformed more than allowable. For this reason, it was manufactured in a shape in which the protruding portion (19) of the metal fitting was inserted into the rubber portion. Since the laminated molded body manufactured by using the metal fitting as shown in FIG. 6 does not have the performance as the laminated molded body up to the portion where the metal fitting is inserted, it is necessary to increase the length of the laminated body accordingly. However, it does not meet the object of the present invention, which requires a small size, and it has a drawback that the cost is increased as a result of the increased labor and material costs. [0006] FIG. 6 shows a case where vulcanization is performed by a method of winding a cloth without using a mold, (i) the length becomes long. (Ii) Since the cloth cannot be wound up to the end portion, the rubber foams. At the same time as solving the problem that, compared with the case of vulcanizing the laminate with a mold, the productivity is high, the disturbance of the hard plate is small, and further, the boundary plates for joining the flanges at both ends are provided, Alternatively, it is an object of the present invention to provide a vibration-damping laminated body having flange-boundary plates having convex cross-sections at both ends. A first aspect of the present invention is to stack a plurality of layers of a hard material and a rubber-like soft material alternately with a rod-shaped core material as a central axis, and the hard material and the rubber-like material at both ends thereof. A plurality of unit laminated compacts having a boundary plate whose cross-sectional shape is almost the same as that of the soft material are concatenated and molded to form a laminated compact, and the outer surface of which is wrapped and fixed by covering with a vulcanizer at high temperature, Separated from the above-mentioned laminated molded body prepared by vulcanizing by heating and pressurizing with high-pressure air or steam, a flange was bonded to the ends of the unit laminated molded body having boundary plates at both ends obtained. A method for producing a vibration-resistant laminated molded article, characterized in that
Secondly, a plurality of layers of hard material and rubber-like soft material are alternately stacked around a rod-shaped core as a central axis, and the cross-sectional shape of the hard material and the rubber-like soft material is almost the same at both ends, and the cross-sectional thickness is With a flange-shaped boundary plate integrally provided with a flange-shaped flange having a diameter of at least 5 mm so that the surface of the plate-shaped body closely contacts the hard material and the rubber-like soft material. To form a unit laminate, and a plurality of the unit laminates are connected to form an integral unit to form a laminate, and a cloth is wound around the outer surface of the laminate to fix the cover, and the laminate is vulcanized. Unit laminate molding in which flange-boundary boundary plates are joined at both ends by separating from the laminate laminate made by vulcanization by heating and pressurizing with high temperature, high pressure air or steam in a can Shaking characterized by the body being obtained In which ON THE manufacturing ary of preventing the molded laminate. In order to manufacture the vibration-proof laminated molded body having the boundary plate of the present invention, the cross-sectional shape is substantially the same as that of the hard material and the rubber-like soft material at both ends of the unit laminated molded body with the rod-shaped core material as the central axis. Or a flange-shaped flange that is integrated with the plate-shaped body at one end is provided at the end of the unit laminate molded body, and a plurality of hard materials and rubber-like soft materials are alternately stacked. Wrap the cloth around the laminated molded body and fix it, and then put it in a vulcanization can, and the temperature is 100 ° C or more, the pressure is 1 to 50 kg.
/ Cm < 2 >, preferably 1 to 10 Kg / cm < 2 > at a high temperature and a high pressure under hot air or steam. A cloth bandage having a width of about 30 to 150 mm is wrapped around the laminated molded body to prevent deformation of the molded rubber-like material in the circumferential direction. At the time of molding, the flange-shaped flange on one side that contacts the rubber-like soft material of the boundary plate is formed with a plate-shaped body having a width of 5 mm or more, preferably 10 to 50 mm, which is the same as the outer shape of the laminated body. Provided integrally with the flange. The hard material forming the unit laminated compact may have the same or slightly smaller cross-sectional shape than the rubber-like soft material. As the rubber-like soft material, natural rubber, ethylene propylene rubber, ethylene propylene diene rubber, nitrile rubber, halogenated butyl rubber, chloroprene rubber, isoprene rubber, styrene butadiene rubber, butadiene rubber, ethylene vinyl acetate rubber, plasticized vinyl rubber,
It is the same as that used as a soft material of conventional laminated materials of this kind such as rubber such as silicone rubber and polyurethane, and its uniform foam. The preferred hardness after vulcanization is JI
The S-A rubber hardness is 30 to 70 degrees. The hard material of the present invention may be formed into a plate or a cord and compounded with the rubber-like soft material. A plate made of this hard material is preferably JIS-A, a metal having a hardness of 95 degrees or more,
Ceramics, FRP, wood, paper, slate board and thermoplastic resins such as polystyrene, polyethylene, ABS resin, polyvinyl chloride, polycarbonate, nylon, polyacetal, ethyl cellulose, phenol resin, urea resin, unsaturated polyester resin, epoxy resin, It can be molded with a thermosetting resin such as an alkyd resin or a melamine resin. The cord is made of an organic fiber such as polyester, nylon, Kepler or rayon, a metal wire such as steel, aluminum or copper, a carbon fiber or the like, preferably 0.
It may be formed to have a diameter of 1 to 3 mm. When molding the above rubber-like soft material and hard material, both are made into a perforated shape having substantially the same inner diameter as the rod-shaped core material, and the perforated rubber-like soft material and perforated hard material are alternately fitted and laminated. Maybe,
Further, a perforated rubberized cloth obtained by coating a mesh or a blind weave using the above cord with the above rubbery soft material and a perforated hard material may be laminated in the same manner. You may laminate only many cloths. In this case, a fixing plate is fixed to one end of the rod-shaped core material of the central shaft, the boundary plate and the perforated material are sequentially laminated, and if a fixing plate is further provided on the other end side, the boundary plate and the perforated material are mutually attached. It is suitable for close contact with. Further, instead of laminating the rubber-like soft material and the hard material, a string of rubber-covered cord obtained by winding a long rubberized cloth around the center rod or coating the cord with rubber is used as a multilayer coil. The boundary plate of the present invention may be attached to what is rolled and formed. The thickness of the rubber-like soft material used for the laminate is preferably 1 to 200 mm, particularly preferably 1 to 5 mm, and the hard plate is preferably 1 to 5 mm. When winding a long rubberized cloth in a roll shape or winding a string of rubber-coated cords in a multilayer coil shape, the preferable arrangement pitch of the cords is the length direction and the radial direction of the rod-shaped core central axis. 0.5 to 8 mm, especially 0.5 to 4
mm is preferred. A method for forming a laminated vibration-preventing laminate having a boundary plate according to the present invention includes one or two boundary plates for each length of one unit laminated body, and after vulcanization. Divide into a plurality of unit laminated compacts at the position of the boundary plate. The boundary plate can be adhered after vulcanization. The inner and outer shapes of laminated rubber can be circular, elliptical, rectangular, star-shaped, triangular, etc., if desired, but the circular shape is the most preferable because it is easy to mold and prevents directionality and is hard to deform. preferable. Width of convex protrusion in cross section of flange / boundary plate (cross section thickness of plate)
Is less than 5 mm, the catch of the cloth wrapped around the laminate will be insufficient, and since it will be the product as it is by vulcanization adhesion,
If it is 0 mm or more, there is a drawback that the product becomes too long. The size of the flange-shaped flange that also serves as the flange is arbitrarily determined according to the purpose. According to the present invention, a boundary plate having substantially the same cross-sectional shape as a hard material and / or a rubber-like soft material laminated on the central axis of a rod-shaped core material or a plate having the same cross-sectional shape and a width of 5 mm or more. Since the end of each unit laminate is fixed by the flange-shaped flange provided with a strip, the outer surface of the fabric is wound tightly to the end, preventing the laminated molded product from losing its shape, and the fabric inside the vulcanization can. Thus, a vibration-proof laminated molded article having a boundary plate which can be fixed with a flange or which also serves as a flange on both ends thereof, which is heated and pressurized by high-temperature air or steam for a short time, is manufactured. The present invention will now be described with reference to the drawings. [FIG. 1] is a cross-sectional view of an embodiment of the present invention, in which (1) is a central axis of a rod-shaped core material, and a fixing plate (2) having a thickness of about 5 mm at both ends,
(2) 'is detachably fixed. Fixed plate (2),
A plurality of desired unit laminate compacts (12) are fitted between (2) ′, and a pair of boundary plates (13) are provided at both ends of each unit laminate compact (12). is there.
After vulcanization, as shown in [Fig. 2], boundary plates (13) are attached to both ends.
Are separated into unit laminated moldings. A desired flange (17) is fastened to the boundary plates (13) at both ends with bolts, glued, welded, or holes are formed in the boundary plates (13) before vulcanization. May be fitted together. Thus, a plurality of unit laminated moldings are manufactured. Further, [FIG. 3] shows a boundary plate (16) having a flange-shaped flange provided with a projection having a convex cross section between the laminated molded body parts (12) of each unit.
It is formed by providing a pair at both ends of 2). In this case, the brim-shaped flange provided with the projection having a convex cross section may be provided only on one end of the unit laminated body. [FIG. 4] shows the vulcanized body separated into one unit laminated body (7). In this case, the boundary plate (16) also serving as a flange.
Since it is bonded, it is not necessary to fasten another flange with a bolt or the like, or to bond or weld it, unlike the conventional unit laminated body. [0016] [FIG. 1] [FIG. 2] [FIG. 3] [FIG. 4] [0020] [Effect of the invention] The effects of the present invention are summarized as follows. The present invention is fixed by winding a cloth around a laminated molded body obtained by alternately stacking a plurality of hard materials and rubber-like soft materials on the central axis of a rod-shaped core material, and heating and pressurizing with hot air or steam in a vulcanizing can. A laminated molded body for finishing by means of a unit laminated molded body having a flange-fixable boundary plate or a flange-shaped flange, and the unit is provided on one side of the flange-shaped flange in contact with the rubber-like soft material. Since a plate-like body having the same cross-sectional shape as the laminated molded body and a width of 5 mm or more, preferably 10 to 50 mm is provided integrally with the flange flange, (a) the cloth wrapped around the surface is made of a rubber-like soft material. It is tightly wound up to the end and does not cause foaming of rubber-like substance or insufficient adhesion of hard plate and boundary plate. (B) Therefore, it is inevitable that the hard material is disturbed. (C) Since the boundary plate of the unit laminated body [FIG. 2] or the flange-combined boundary plate having a convex cross section is firmly adhered to the end of the unit laminated body, the flange is stopped with a bolt after vulcanization. It is easy to wear, and in the case of a boundary plate that also serves as a flange, since it also serves as a flange, it is not necessary to fasten the flange and it can be used as it is as a vibration-proof laminated body. (D) In the case of a unit laminated body having a boundary plate as shown in FIG. 2, a flange having a desired free shape can be easily attached, and the range of use of the vibration preventing laminated body is large. In the case of a unit laminate molded body having a boundary plate that also serves as a flange, it is not necessary to fasten the flange with a bolt, so labor saving and cost reduction are large compared to conventional products.
