Problems solved by technology

[0002] The existing plastic track is usually made of black particles and glue to make the base, and the surface layer is mixed with EPDM colored particles and glue to spread evenly. The plastic track obtained by this scheme cannot meet the needs of children in terms of environmental performance and physical properties. Requirements, because this kind of plastic runway has poor elasticity and strong hardness, children are easily injured; and VOCs that may volatilize and cause heavy pollution, the existing technology has no solution to this

Abstract

The invention provides an elastic protective runway and a preparation method thereof. The elastic protective runway comprises a basic layer, a buffer layer and a surface layer which are sequentially arranged from bottom to top. The buffer layer is prepared from polyurethane glue and high-elasticity foaming particles. The surface layer is prepared from polyurethane glue and SPPR particles. The VOCs content is not detected, benzene, methylbenzene, dimethylbenzene, formaldehyde and other solvent matter are not contained, chlorinated paraffin and six phthalate plasticizers are not contained, high cancerogenic pramoxine is not contained, 18 kinds of polyaromatic hydrocarbon are not contained, soluble lead, chromium, cadmium, mercury and other heavy metals are not contained, and the physical performance of the finished product is good. The service life is long and is 4-5 years longer than traditional plastic, product advantages are obvious, all colors can be matched at will to achieve a dazzling effect, and the elastic protective runway is good in antiskid performance, resistant to degradation and fading, soft, sanitary, free of toxins and smells, capable of being recycled 100% and capable of being used indoors and outdoors. The double-layer arrangement is adopted, in other words, the SPPR particles are adopted for the top layer, the high-elasticity foaming particles are adopted for the bottom layer, and therefore the elasticity of the runway is improved.

Description

Technical field: [0001] The invention relates to an elastic protective runway and a preparation method thereof. Background technique: [0002] The existing plastic runway is usually made of black particles and glue, and the surface layer is mixed with EPDM colored particles and glue to be evenly paved. The plastic runway obtained by this scheme cannot meet the needs of children in terms of environmental performance and physical performance. Because of poor elasticity and strong hardness of this kind of plastic runway, children are easily injured; and VOCs that may cause heavy pollution may be volatilized, and the existing technology has no solution to this. Invention content: [0003] The purpose of the present invention is to provide an elastic protective runway and a preparation method thereof in view of the above shortcomings of the prior art, which are environmentally friendly, safe, durable, and solve the problems existing in the prior art. [0004] The technical sch...
