1. A method for manufacturing a multilayer treadmill walking board assembly, comprising:
a first step of preparing a plurality of components having a weight proportion including: a resin of 100 g, a catalyst of 0.2-0.8 g, a hardener of 0.5-2.5 g, a mineral powder of 20.0-45.0 g, a lubricating oil of 5.0-10.0 g, and a graphite mixture of 15.0-40.0 g;
a second step of mixing and stirring the components to form a composite material;
a third step of heating the composite material to a first temperature of 140-160° C.;
a fourth step of cooling the composite material to a second temperature of 80-85° C. so that the composite material is disposed at a thick state;
a fifth step of applying the composite material on a top face of a support board, to form a coating on the support board;
a sixth step of solidifying the coating during a time interval of 2-5 minutes;
a seventh step of rapidly cooling the coating to a third temperature of 20-30° C., with the composite material of the coating producing a stepwise multilayer deposit gradually by relatively different specific gravity and different types of the components during a cooling solidification process, thereby serially forming a wear-resistant layer, a lubricating layer, and an antistatic layer from bottom to top; and
an eighth step of solidifying the coating to form a product which includes the wear-resistant layer, the lubricating layer located above the wear-resistant layer, and the antistatic layer located above the lubricating layer.
