USE - Anti-aging plastic runway. ADVANTAGE - The anti-aging plastic runway has excellent resistance to stress caused by aging and exercise. DETAILED DESCRIPTION - An anti-aging plastic runway comprises a bottom layer, a base layer and a surface layer, which are provided from bottom to top. The bottom layer comprises a sandy soil layer, a gravel layer, a coarse asphalt layer, a fine asphalt layer, a moisture-proof layer and a cement concrete layer, which are sequentially provided from bottom to top. The base layer comprises a waterproof coating layer, a gypsum powder layer, a wood fiber film, a vulcanized silicone rubber layer and an ethylene-propylene diene monomer rubber particle layer, which are sequentially provided from bottom to top. The surface layer comprises an elastic functional layer and an ultraviolet protection layer, which are sequentially provided from bottom to top. The elastic functional layer comprises 90-120 pts. wt. paraformaldehyde, 15-30 pts. wt. polypropylene glycol, 40-50 pts. wt. diphenylmethane diisocyanate, 35-50 pts. wt. polyisocyanate, 30-45 pts. wt. dibutyl phthalate, 20-30 pts. wt. dimethylethanolamine, 5-8 pts. wt. silicone powder, 5-8 pts. wt. epoxidized soybean oil, 8-12 pts. wt. polyurethane curing agent, 20-30 pts. wt. rosin, 15-20 pts. wt. graphene, 15-30 pts. wt. plasticizer, 10-15 pts. wt. stabilizer, 1-2 pts. wt. catalyst, 1-1.5 pt. wt. antioxidant, 1-1.5 pts. wt. zinc borate flame retardant, 5-15 pts. wt. anti-slip additive and 5-8 pts. wt. pigment. An INDEPENDENT CLAIM is included for preparation of anti-aging plastic runway, which involves finishing the ground on which the aging-resistant plastic runway is to be laid, then laying sandy soil layer, gravel layer, coarse asphalt layer, fine asphalt layer, moisture-proof layer and cement concrete layer, in order, laying waterproof coating layer, gypsum powder layer, wood fiber film, vulcanized silicone rubber layer and ethylene-propylene diene monomer rubber particle layer on the cement concrete layer in order, mixing paraformaldehyde, polypropylene glycol and dimethylethanolamine, obtaining a component (A), mixing diphenylmethane diisocyanate, polyisocyanate, dibutyl phthalate, silicone powder, epoxidized soybean oil, polyurethane curing agent, rosin, graphene, plasticizer, stabilizer, catalyst, antioxidant, zinc borate flame retardant, anti-slip additive and pigment, obtaining a component (B), adding the component (A) to a reactor, dehydrating, introducing nitrogen, cooling, adding the component (B), stirring, reacting, obtaining elastic functional layer casting material, pouring the elastic functional layer casting material on the ethylene-propylene diene monomer rubber particle layer, obtaining elastic functional layer, and pouring ultraviolet protection layer casting material on the elastic functional layer.
