Description
Technical Field
The invention belongs to the technical field of plastic runways, and particularly relates to an environment-friendly high-elasticity acrylic plastic runway and a production method thereof.
Background
Plastic runways are an indispensable important facility in modern track and field sites. Compared with the traditional soil track, the novel soil track has the advantages of good elasticity, skid resistance, wear resistance, shock absorption, easy field nursing, bright color, attractive appearance, orderliness and the like. The plastic track paved in China at present is a Polyurethane (PU) track which takes oily bi-component Polyurethane (PU) as an adhesive. The runway has the following defects: firstly, organic solvents (such as dimethylbenzene or ethyl acetate and the like) added in the construction process are volatile, pollute the environment and harm the bodies of construction personnel; secondly, the materials need to be prepared and used at present, the construction is troublesome, and the loss and the waste of the materials are easily caused.
In recent years, acrylic tracks have emerged to replace conventional polyurethane tracks, solving the above-mentioned problems. The water-based acrylic resin plastic track and the production method thereof disclosed in the Chinese patent CN102733289B are disclosed, the track comprises a base layer, a damping layer, a wear-resistant layer and a cover protective layer which are sequentially bonded together from bottom to top, wherein the base layer comprises a base and base oil which is coated on the upper surface of the base in a scraping way; the shock absorption layer is formed by mixing and stirring runway base rubber and styrene butadiene rubber particles and then paving the mixture on the base oil; interlayer enhanced base oil is sprayed on the damping layer; the wear-resistant layer is formed by mixing and stirring runway rubber, ethylene propylene diene monomer rubber particles and ethylene propylene diene monomer rubber powder and then paving the mixture on the interlayer enhanced base oil; the top protection layer is formed by spraying the mixture of the top protection glue and water on the wear-resistant layer. The water-based acrylic resin runway provided by the invention does not contain substances harmful to human bodies and the environment, and is an environment-friendly product. However, the elasticity of the acrylic resin is weaker than that of the polyurethane, so that the elasticity of the runway is reduced, and the use experience of the runway is reduced.
Therefore, there is a need to provide a high-elasticity acrylic track, which is environmentally friendly and ensures the high-elasticity experience of the track.
