It concerns the elastic blocks laid out on golf courses, tennis courts, poolsides, etc.

いる（特開平１−１９７５１７号公報参照）。Conventional technology Conventionally, commercially available elastic paving molded products are made of powdered rubber made from filamentous rubber scraped off by a tire repair device or powdered rubber made by crushing waste rubber such as old tires.
It is known that the material is cured and molded using a synthetic resin binder (see JP-A-1-197517).
また、タイヤの粉末ゴムを使用した成型物は殆どが黒色
であるため、黒色以外の成型物を得る場合は、バインダ
ーに顔料を配合させ硬化と同時に粉体の表面を有色化さ
せる方法が主に行なわれている。In addition, most molded products using powdered tire rubber are black, so if you want to obtain a molded product other than black, the main method is to add pigment to the binder and color the surface of the powder at the same time as it hardens. It is being done.
さらに、多層構造物を形成する場合は、表面層を着色塗
料等を用いて成型後に塗布（コーティング）を行なう方
法等がとられている。Furthermore, when forming a multilayer structure, a method is used in which the surface layer is coated with a colored paint or the like after molding.

部分は極端に薄く、塗装の剥れ等により美観を損われる
問題点があった。Problems to be Solved by the Invention However, in a molded article using a synthetic resin binder as in the prior art, the surface (tread surface) layer is easily deteriorated by abrasion, acid, ozone (O3), etc. In particular, products based on crushed tire rubber or recycled rubber chips have low resistance to ozone, light, etc. Furthermore, when a pigment or the like is added to the binder in order to color the surface layer for the purpose of improving aesthetics, there is a problem in that the inherent strength of the binder is reduced in proportion to the strength before the addition of the pigment. Furthermore, in the method of painting and coloring the surface layer, the colored part is extremely thin, and there is a problem that the appearance is spoiled due to peeling of the paint, etc.
本発明は、このような従来の問題点に着目して創案され
たものであって、長期にわたり、歩行者や自然条件等に
起因する表面層の変色、摩耗、劣化を抑止し、表面層の
美観及び成型体自体の強度を保つことができる加硫ゴム
チップ成型体を得んとするものである。The present invention was devised by focusing on these conventional problems, and suppresses discoloration, abrasion, and deterioration of the surface layer caused by pedestrians, natural conditions, etc. over a long period of time, and improves the surface layer. The object of the present invention is to obtain a vulcanized rubber chip molded body that can maintain the beauty and strength of the molded body itself.
