あった。(Technical background of the invention and its problems) Conventionally, vibration isolating materials have been composed of metal parts arranged concentrically and molded parts of a rubber-like nydistomer fixed between the metal parts. Many things are used. To fully manufacture such a vibration damping material, the metal part coated with adhesive on the inner interface is placed in a mold, and the elastomer is completely injected between the n-ply and the entire part is heated to completely cure the elastomer. has been taken. However, with this method,
In addition to poor productivity and high manufacturing costs, there were problems in that it was difficult to set the molding temperature and pressure conditions for the elastomer to ensure complete adhesion between the metal and the nidistomer.

製造方法が提案さしている。In order to solve all of these problems, polyether resin (hereinafter referred to as P, P.0 resin) was used instead of metal, and the inner and outer mold cavities were coated with this resin in a concentric manner and isolated from each other. A continuous manufacturing method for a vibration damping material in which both the hard part and the soft part are made of lastic material is proposed, in which both the hard part and the soft part are injection molded into the mold cavity, and then the entire part is injection molded between the mold cavities. There is.

製造方法である。0 resin is simultaneously injected to form a molded body, and before the resin slightly hardens and reaches maximum hardness, S is injected into a third mold cavity disposed between the first and second mold cavities. ,
75 to 50% by weight of B, S resin (hereinafter simply referred to as 0) and styrene-ethyl B, 8 resin. ) 25 to 50% of the composition is heated and melted, the whole is injected to form a molded body, and the first and second molded body parts and the third molded body part are directly joined. This is a method for manufacturing vibration isolating materials that has all the following characteristics.

樹脂からなる第1および第2の成形体部分との接着強度
が不充分となり実用に供し得ないためである。If the blending ratio of E, B, and 8 resins is less than 25% of the total composition and the ratio of S, B, and S resins exceeds 75%, the effect of improving the heat resistance of the third molded body portion is almost negligible. On the contrary, if the blending ratio of S, E, B, 54f1 fat exceeds 50%, 8.
If the deflection of B, S resin is less than 50%, P, P, 0
This is because the adhesive strength with the first and second molded body parts made of resin is insufficient and it cannot be put to practical use.
