Problems solved by technology

However, traditional sports paving materials are all opaque. If more functional settings are required, such as lighting, energy storage, etc., it is necessary to divide specific functional areas on the paving materials and make special structural settings to obtain them. The overall sports performance of the sports paving has adverse effects, and the appearance is not beautiful enough, and the production is time-consuming and labor-intensive

preparation example Construction

[0034] The preparation method of the above-mentioned transparent sports surface layer comprises the following steps:

[0035] mixing the 2-hydroxyaniline and the polyether polyol, and performing dehydration;

[0036] Then add the diisocyanate to the mixed material after the dehydration treatment to carry out polyaddition reaction; then add the diluent, drier and fumed silica, and stir;

[0037] Lay the mixed material after stirring, and solidify and shape it.

[0038] Instead of directly using polyurethane resin, the matrix resin is prepared by polyaddition of polyether polyol and diisocyanate, and at the same time, the order of adding each raw material is reasonably controlled. First, mix the 2-hydroxyaniline and polyether polyol and carry out The dehydration treatment is conducive to the subsequent full contact reaction with diisocyanate, and the dispersion of fumed silica in the matrix resin, thereby ensuring the physical and chemical properties of the prepared sports surf...

Embodiment 1-5

[0050] Embodiment 1-5 provides 5 kinds of sports paving materials, and its raw material components are as shown in table 1 (parts by weight):

[0051] Table 1

[0052]

[0053]

[0054] The preparation method of above-mentioned sports pavement is as follows:

[0055] (1) Put polyether polyol and 2-hydroxyaniline into the reaction kettle, heat to 100°C, stir and mix, and vacuum dehydrate for 60min;

[0056] (2) The temperature of the material in the reaction kettle is lowered to 80°C, then diisocyanate is added, mixed and stirred, heated and kept at 95°C for 2.5h;

[0057] (3) Cool to ≤50°C, then add diluent, stir for 30 minutes, and cool to room temperature;

[0058] (4) Add drier and fumed silica, stir evenly, and vacuumize for 30 minutes;

[0059](5) Lay out materials, and use runway paving tools or spraying equipment to spread or spray the materials on the bottom film or the designated area and mold on the ground, and then cure and shape.

Abstract

The invention relates to a transparent sports surface layer, a preparation method thereof and a sports paving material; wherein the transparent sports surface layer is prepared from the following rawmaterial components in parts by weight: 10-25 parts of diisocyanate, 50-100 parts of polyether polyol, 1-5 parts of 2-hydroxyaniline, 10-30 parts of a diluent, 1-5 parts of a drier and 2-10 parts of fumed silica. The whole sports surface layer is transparent, manufacturing of multifunctional (such as light emitting and energy storage) sports paving materials is facilitated, meanwhile, the sports performance is good, and the appearance is attractive.

Description

technical field [0001] The invention relates to the technical field of sports equipment, in particular to a transparent sports surface layer, a preparation method thereof, and a sports paving material. Background technique [0002] The ground of the modern sports field, such as the runway and the court, needs to be paved with sports paving materials, so that the sports field has suitable elasticity, anti-slip and good safety performance. [0003] With the improvement of people's living standards, the requirements for sports fields are also getting higher and higher. More functional and more beautiful sports pavements are in line with market demand. However, traditional sports paving materials are all opaque. If more functional settings are required, such as lighting, energy storage, etc., it is necessary to divide specific functional areas on the paving materials and make special structural settings to obtain them. The overall sports performance of the sports paving has ad...
