Embodiment 1

[0023] Such as figure 1 As shown, the present invention provides a technical solution: a water-based mixed plastic runway, including a plastic surface layer, an asphalt concrete layer, an intermediate layer 400 and a surface layer, and the plastic surface layer is made of polyurethane prepolymer, calcium carbonate and PU particles are combined, and ultraviolet absorbers and iron oxide are added. The asphalt concrete layer includes AC-10 fine-grained asphalt concrete layer 200 and AC-20 coarse-grained asphalt concrete layer 300. The middle layer 400 is Ash stone or cement stabilized crushed stone base, the surface layer includes crushed stone layer 500 and notoginseng ash layer 600600, the plastic track from top to bottom is the plastic surface layer, AC-10 fine-grained asphalt concrete layer 200, AC-10 -20 coarse-grained asphalt concrete layer 300, limestone, crushed stone layer 500 and notoginseng ash layer 600600, and several plastic particles are evenly distributed on the s...

Embodiment 2

[0027] The difference from Example 1 is:

[0028] From top to bottom, the plastic runway consists of plastic surface layer, AC-10 fine-grained asphalt concrete layer 200, AC-20 coarse-grained asphalt concrete layer 300, cement-stabilized gravel base, gravel layer 500 and Sanqi ash layer 600600, and several plastic particles are evenly distributed on the surface of the plastic surface.

[0029] The thickness of the plastic surface layer is 13mm, and the plastic surface layer also includes sulfur, stearic acid, anti-aging agent and accelerator, and the parts by weight of each component of the plastic surface layer are respectively: 70 parts of polyurethane prepolymer, carbonic acid 15 parts of calcium, 0.6 parts of ultraviolet absorber, 4 parts of iron oxide, 7 parts of sulfur, 15 parts of stearic acid, 4 parts of anti-aging agent, 6 parts of accelerator.

Embodiment 3

[0031] The difference from Example 1 is:

[0032] From top to bottom, the plastic runway consists of plastic surface layer, AC-10 fine-grained asphalt concrete layer 200, AC-20 coarse-grained asphalt concrete layer 300, cement-stabilized gravel base, gravel layer 500 and Sanqi ash layer 600600, and several plastic particles are evenly distributed on the surface of the plastic surface.

[0033] The thickness of the plastic surface layer is 13mm, and the plastic surface layer also includes sulfur, stearic acid, anti-aging agent and accelerator, and the parts by weight of the components of the plastic surface layer are respectively: 80 parts of polyurethane prepolymer, carbonic acid 20 parts of calcium, 0.9 parts of ultraviolet absorber, 6 parts of iron oxide, 10 parts of sulfur, 20 parts of stearic acid, 5 parts of anti-aging agent, and 8 parts of accelerator.

[0034] Among the above raw materials, the working principle of cement-stabilized gravel is: cement-stabilized gravel ...

Abstract

The invention discloses a waterborne mixed type plastic track. The waterborne mixed type plastic track comprises a plastic-surface surface layer, an asphalt concrete layer, a middle layer and a ground surface layer, the plastic-surface surface layer is formed by combining a polyurethane prepolymer, calcium carbonate and PU particles, an ultraviolet light absorber and ferric oxide are added, the asphalt concrete layer is composed of an AC-10 fine particle type asphalt concrete layer and an AC-20 coarse particle type asphalt concrete layer, the middle layer is a lime stone or cement stable gravel base layer, the ground surface layer comprises a gravel layer and a 37 lime earth layer, the plastic track is the plastic-surface surface layer, the AC-10 fine particle type asphalt concrete layer, the AC-20 coarse particle type asphalt concrete layer, the middle layer, the gravel layer and the 37 lime earth layer from the top to the bottom, and several plastic particles are evenly distributed on the plastic-surface surface layer. The waterborne mixed type plastic track is simple in material structure and good in abrasion resistance, and the track has high performance parameters in all aspects.

Description

technical field [0001] The invention relates to the technical field of plastic runways, in particular to a water-based mixed plastic runway. Background technique [0002] The plastic track is also called the all-weather track and field track. It is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. The plastic runway has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to athletes' speed and technical performance, effectively improving sports performance and reducing the rate of falls. The plastic runway is composed of polyurethane rubber and other materials. It has certain elasticity and color, and has certain anti-ultraviolet ability and aging resistance. It is internationally recognized as the best all-weather outdoor sports floor material. [0003] The track refers to the sport...
