【発明の詳細な説明】 本発明は合成ゴムとコルクの弾性体に関する。[Detailed description of the invention] The present invention relates to an elastic body made of synthetic rubber and cork.

れらの欠点を除去改良することにある。Conventionally, mixed molded products of cork grains and synthetic rubber have been widely known as gasket materials, building materials, vibration-proofing materials, and the like. Due to the characteristics of the rubber, internal mixers are used to manufacture these.
It requires kneading with cork using rolls, and after sheeting and vulcanization, the resulting product has large differences in properties in the There were issues such as changes. The object of the present invention is to eliminate and improve these drawbacks.

比重、強度、弾性のものが得られる。The present invention involves cross-linking a mixture of synthetic rubber and cork grains in a certain shape using a conventional method, then coarsely crushing and selecting the mixture using a crusher, and then converting the crushed product into a heat-resistant, water-resistant, and flexible synthetic resin. It is agglomerated and molded with adhesive or rubber adhesive. The elastic body of the molded product obtained in this way has good dimensional stability because it does not have the directional properties of x direction and y direction with respect to the sheeting direction as shown in the figure, and it also has good dimensional stability. The mixing ratio with the adhesive and the filler (for example, cork grains) can be freely controlled, and the specific gravity of the aggregated elastic body can be freely controlled, so that desired specific gravity, strength, and elasticity can be obtained.
