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 transparent moving surface layer includes the following steps:

[0035] Mix the 2-hydroxypanyiline and the polyether polyol, and dehydrated treatment;

[0036] The diisocyanate is then added to the mixed material after the dehydration treatment, and the polymerization reaction is carried out; then the diluent, the driedrite and the gas phase white carbon are added, stirred;

[0037] The stirred mixed materials were laid and solidified.

[0038] The polyurethane resin is not directly employed, but the preparation of the matrix resin is carried out by polyether polyol and diisocyanate, and the addition sequence of each raw material is simultaneously controlled, and the 2-hydroxy aniline and polyether polyol are mixed. Dehydration treatment is conducive to the sufficient contact reaction with diisocyanate, as well as gas-phase white carbon black in the matrix resin, thereby ensuring the preparation of the physical and chemical properties of ...

Embodiment 1-5

[0050] Examples 1-5 provide five kinds of sports layers, and the raw material components are shown in Table 1 (parts by weight):

[0051] Table 1

[0052]

[0053]

[0054] The preparation method of the above-mentioned exercise sheet is as follows:

[0055] (1) Putting the polyether polyol and 2-hydroxy aniline into the reactor, heated to 100 ° C, stir mixing, vacuum dehydration for 60 min;

[0056] (2) The material in the reactor is cooled to 80 ° C, then diisocyanate, mix stirring, heating and holding 95 ° C 2.5 h;

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

[0058] (4) Add a drum and gas phase white carbon, stir evenly, vacuum 30min;

[0059](5) Drainage, and use runway paving tools or spray equipment, the material is paved or sprayed on the underlying film or the design, and the solidification is formed.

Abstract

The invention relates to a transparent sports surface layer, a preparation method thereof, and a sports paving material. The transparent sports surface layer is made of various raw material components including the following parts by weight: 10-25 parts of diisocyanate, 50-100 parts of polyether polyol, 1-5 parts of 2-hydroxyaniline, and 10-30 parts of diluent , 1-5 parts of drier, and 2-10 parts of fumed white carbon black. The sports surface layer is transparent as a whole, which is beneficial to the production of multi-functional (such as luminous, energy storage) sports paving materials, and meanwhile has good sports performance and beautiful appearance.

Description

Technical field [0001] The present invention relates to the technical field of moving equipment, and more particularly to transparent moving surface layers and preparation methods thereof, motion sheets. Background technique [0002] The raceway of the modern sports field is required to lay the laying of sports, so that the sports field has an elastic, non-slip and good safety. [0003] As people's living standards are increasing, the requirements for sports fields are getting higher and higher. More features, a more beautiful sports layout is in line with market demand. The traditional sports layout is opaque, as needed to make more functional settings, such as illumination, energy storage, etc., all need to be divided into specific ribs and special structural settings, which is inevitably The overall exercise performance of the exercise sheet is adversely affected, and the shape is not beautiful enough, and the production is expected. Inventive content [0004] Based on this, ...
