実施例
以下、本発明に係る加硫ゴム粉末成形物の複合体形成方
法の詳細を実施例に基づいて説明する。EXAMPLES Hereinafter, details of the method for forming a composite of vulcanized rubber powder molded articles according to the present invention will be explained based on examples.

処理（バッキング等）を施す。First, in this embodiment, as shown in FIG. 1, artificial turf 2 is placed on the inner bottom of a mold 1 in an upside-down state (the base fabric is in a "-" state). Note that the back surface of the artificial grass 2 is subjected to an adhesive treatment (backing, etc.) for adhesion.
なお、人工芝２は、基布部がポリエステル、起毛部がナ
イロンで構成されている。Note that the artificial grass 2 has a base fabric portion made of polyester and a raised portion made of nylon.

Polyisocyanate 1. (trade name rMDI-LK-, 1 Mitsui Toatsu Chemical Co., Ltd.) 42.5 parts by weight is stirred at high speed for a short period of time and mixed with recycled rubber dip (powder) material. It is desirable that the mixing with the recycled rubber dip material be carried out promptly before the viscosity increases due to the reaction of the binder. The purpose of blending the polyether polyol with the hydroxyl-terminated polybutadiene is to lower the viscosity and reduce the blending cost.

上でも成形は可能である。The blending ratio of the recycled rubber dip material (vulcanized rubber powder) and the binder mixture is as follows: recycled rubber dip material: 100 parts by weight, binder mixture: 5 to 40 parts by weight. If the binder mixture does not contain 5 parts by weight or more, the effect as a binder will be small, but it is not necessary to limit the binder mixture to 40 parts by weight, and molding can be performed even if the amount is more than 40 parts by weight.
