【発明の詳細な説明】
従来、自動車のウレタンハンパ成形型内の製品成形空間
へのウレタン樹脂注入口はウレタンハンパ成形後、ウレ
タンバンパから切断されて屑となり。DETAILED DESCRIPTION OF THE INVENTION Conventionally, a urethane resin injection port into a product molding space in a urethane damper mold for an automobile is cut off from the urethane bumper after the urethane damper is molded, and becomes waste.
この屑とウレタンバンパの不良品となる焼却廃棄されて
いた。This scrap and the urethane bumper were considered defective and were disposed of by incineration.
しかし、省資源の観点からは好ましくなく、また解却時
に悪臭が発生するという不具合があった。However, this is not desirable from the viewpoint of resource conservation, and it also has the problem of emitting a bad odor when dismantled.
本発明は特許請求の範囲に記載されたように構成されて
いるので、ウレタンバンバの屑および不良品を廃棄する
必要がなくなり資源を節約できるものである。Since the present invention is constructed as described in the claims, there is no need to dispose of urethane bumper waste and defective products, thereby saving resources.
以下１本発明の一実施例について具体的に説明する。An embodiment of the present invention will be specifically described below.

プレー状に塗布し、さらに良く混合して混合体を形成す
る。混合時間は約１５〜２０分。Tilt 5 or less to remove defective urethane hampers and scraps.
0%, chip urethane 2o%, urethane adhesive 30%
Add 20% by weight to the raw material (each % by weight), pulverize and mix with a stirring mixer, and during mixing, apply a urethane resin adhesive to the raw material in the form of a spray of 10 to 20% by weight to make it even better. Mix to form a mixture. Mixing time is approximately 15-20 minutes.
上記混合体を成形型に投入してプレスにより加圧し、同

き込むことにより混合へを硬化成形し遮音材を形成する
。The above mixture is put into a mold and pressurized by a press, and at the same time steam is blown from the mold into the mixture for 2 to 6 minutes to harden and mold the mixture to form a sound insulating material.
この遮音材は車体の中央を前後方向に延びるフロアトン
ネルを形成するフロアパネルに装着して使用されるもの
である。This sound insulating material is used by being attached to a floor panel that forms a floor tunnel extending longitudinally through the center of the vehicle body.

プであると成形性が悪くなり好ましくない。Side note: - In the above example, 20% by weight of the pulverized urethane/component was added to the raw material, but it is fine as long as it is less than 30% by weight; This will cause cracks. The amount of the above crushed product is 10~
20% by weight is most preferable from the viewpoint of moldability. Moreover, if the pulverized urethane bumper has more than 5 chips, the moldability will deteriorate, which is not preferable.
