Embodiment 1

[0024] A luminous elastic plastic runway and walking track, prepared from the following components by weight: 15 parts of anti-yellowing polyurethane prepolymer, 5 parts of chain extender, 79 parts of long afterglow polyurethane luminous elastic particles, 1 The diameter of the long-lasting polyurethane luminous elastic particles is 1.5 mm, and the antioxidant is antioxidant 1010.

[0025] The anti-yellowing polyurethane prepolymer is formed by prepolymerizing 30 parts by weight of hexamethylene diisocyanate (HDI) and 70 parts by weight of polyether polyol with a molecular weight of 1000-3000.

[0026] The chain extender is synthesized by dehydrating 1 part by weight of dimethylthiotoluenediamine (DMTDA) and 23 parts by weight of polyether polyol with a molecular weight of 1000.

[0027] The long afterglow polyurethane luminous elastic particles are composed of 55% Nco and 10% polyurethane prepolymer, 5% of 800 mesh transparent glass powder is added, the transparent glass is s...

Embodiment 2

[0029] The difference from Example 1 is that the long afterglow polyurethane luminous elastic particles are made of 59% hot-melt polyurethane (TPU) and 4% of 600 mesh transparent glass powder is added in the mixer, and the transparent glass is potassium Lead silicate glass, add 5% epoxy soybean oil, 1% antioxidant 1010, 24% nano-scale rare earth silicate luminous powder and 6% rare earth trivalent ion europium (Eu) and β-diketone complex And 1% vulcanizing agent (TAIC), after stirring evenly, heat-melt and extrude in a hot-melt extruder, press it into a 5mm thick rubber sheet with a roller press, and then crush it into elastic particles with a diameter of 3-4mm .

Embodiment 3

[0031] The difference from Example 1 is that it is prepared from the following components by weight: 23 parts of anti-yellowing polyurethane prepolymer, 7 parts of chain extender, 68 parts of long-lasting polyurethane luminous elastic particles, 2 parts The antioxidant of part; The anti-yellowing polyurethane prepolymer is formed by prepolymerization of 40 parts by weight of isophorone diisocyanate (IPDI) and 60 parts by weight of polyether polyol with a molecular weight of 1000-3000.

[0032] In the preparation of the long afterglow polyurethane luminous elastic particles, the elastic particles with a diameter of 2-3 mm are pulverized into elastic particles with a pulverizer after complete curing.

Abstract

The invention discloses a luminous elastic plastic track and a vigorous walking track. The luminous elastic plastic track and the vigorous walking track are prepared from components in parts by weightas follows: 15-23 parts of a yellowing-resistant polyurethane prepolymer, 5-7 parts of a chain extender, 68-79 parts of long-afterglow polyurethane luminous elastic particles with the diameter of 1-4mm and 1-2 parts of an antioxidant. The a luminous elastic plastic track and the vigorous walking track contain no volatile toxic substances, chlorinated paraffin, phthalate plasticizers or harmful substances such as MOCA. In some implementation modes, the luminous elastic plastic track and the vigorous walking track have the tensile strength of 0.5 MP or above, the elongation at break of 90% orabove and impact absorption of 35% or above and can emit light continuously for 10 h or longer after being exposed to sunlight or light for 2 h.

Description

technical field [0001] The invention belongs to the field of sports equipment, and in particular relates to a luminous elastic plastic runway, a walking track and a preparation method thereof. Background technique [0002] In recent decades, light-storing self-luminous materials have been widely used in fields such as fire protection, transportation, printing and dyeing, daily necessities, etc. paint etc. [0003] TDI type polyurethane runway has high volatility and high hazard, which will cause great harm to the environment and human health. At the same time, with the development of comprehensive fitness sports, the demand for various sports venues is increasing. Especially for office workers, evening and night exercises require luminous sports venues. At present, there are no long-lasting luminous sports venues. Contents of the invention [0004] In order to solve the above-mentioned problems, the present invention proposes a kind of energy-saving, green, environmental...
