Abstract
The invention discloses a shock-absorbing type training runway material and a preparation process thereof. Compared with the prior art, the material prepared by the invention is used for paving the physical training runway, has good elasticity, and plays a role in shock absorption, thereby avoiding the injury of athletes.
Description
Technical Field
The invention relates to the technical field of materials, in particular to a damping type physical training runway material and a preparation process thereof.
Background
The runway refers to a path for competition such as running, speed skating, racing and the like on a sports ground, in the prior art, the runway material on the sports ground is too hard, so that the running training vibration is large, the strain of athletes is serious, and if the runway material is filled to be softer, the strength is not enough, the runway is easy to damage, so that the improvement space exists.
Disclosure of Invention
The invention aims to solve the problems and provide a shock-absorbing type training runway material and a preparation process thereof.
The invention realizes the purpose through the following technical scheme:
the invention relates to a shock-absorbing type training runway material which is composed of natural rubber, nitrile rubber, polyamide acid resin, high-activity polymer polyol, ethylene glycol, diethanol amine, acrylic ester, ethylene-vinyl acetate copolymer, quartz sand and a gum base.
Preferably, each part comprises, by weight, 25% of the natural rubber, 15% of the nitrile rubber, 15% of the polyamic acid resin, 5% of the high-activity polymer polyol, 2% of the ethylene glycol, 5% of the diethanolamine, 8% of the acrylate, 2% of the ethylene-vinyl acetate copolymer, 8% of the quartz sand and 15% of the gum base.
The invention relates to a preparation process of a damping type physical training runway material, which comprises the following steps:
(1) crushing quartz sand into powder for later use;
(2) placing natural rubber and nitrile rubber into a container, heating to 220 ℃ and 230 ℃ for melting;
(3) mixing the quartz sand obtained in the step (1) with polyamide acid resin, high-activity polymer polyol, ethylene glycol, diethanol amine, acrylic ester, ethylene-vinyl acetate copolymer and gum base, adding the mixture into the heated container obtained in the step (2), uniformly mixing, and cooling after the mixture is completely melted;
(4) and crushing the cooled materials into 5mm granules.
The invention has the beneficial effects that:
compared with the prior art, the material prepared by the invention is used for paving a physical training runway, has good elasticity and a shock absorption effect, so that the injury of athletes is avoided.
Detailed Description
The invention is further illustrated below:
