Problems solved by technology

[0004] The traditional prefabricated coil surface can solve most of the defects of on-site ingredient processing and paving, but in the case of extremely high density of use, such as the starting area of ​​​​professional athletes, because there will be spikes pedaling hard all the year round, the runway area is easy to wear and destroyed

preparation example Construction

[0038] A preparation method of the above-mentioned prefabricated sports field surface layer material, comprising the following steps:

[0039] (1) mixing described natural rubber, styrene-butadiene rubber, corundum powder, white carbon black, mineral oil, paraffin and functional additives, and banburying;

[0040] (2) Carrying out kneading of the banburying material obtained in step (1), cooling after the sheet is discharged, to obtain an unvulcanized rubber sheet;

[0041] (3) banburying the unvulcanized film with the zinc oxide and accelerator, and then calendering the film to obtain the film;

[0042] (4) vulcanize the film obtained in step (3), and cool it down.

[0043] In some of the embodiments, in step (1), the banburying time is 5-15 minutes, and the banburying temperature is 110-140°C.

[0044] In some of these embodiments, in step (3), the temperature at which the film is mixed with the zinc oxide and the accelerator is ≤70°C.

[0045] In some of these embodiment...

Embodiment 1-4

[0055] A kind of prefabricated playground surface layer material, by weight, raw material composition is as shown in table 1:

[0056] Table 1

[0057]

[0058] The preparation method of the prefabricated sports field surface layer material is as follows:

[0059] (1) Weigh natural rubber, styrene-butadiene rubber, emery powder, white carbon black, naphthenic oil, paraffin, pigment, antioxidant 2246 and antioxidant 1010, mix and place in a rubber internal mixer, 110-140 Banburying at ℃ for 10 minutes to obtain banburying materials;

[0060] (2) Place the banburying material in an open mill, roll it out at 40-60°C for 10 minutes, and control the thickness of the film to ≤2mm, cool it until the temperature of the film is ≤50°C, and obtain an unvulcanized film for use;

[0061] (3) Mix the unvulcanized rubber sheet obtained in step (2) with the zinc oxide, TMTD, BZ, M and DM in said parts by weight, place in a rubber mixer, mix at a temperature lower than 70°C, and then extr...

Abstract

The invention relates to a prefabricated sports field surface material and a preparation method thereof. The prefabricated sports field surface material is prepared from, by weight, 70-90 parts of natural rubber, 10-30 parts of styrene-butadiene rubber, 70-90 parts of silicon carbide powder, 30- 50 parts of white carbon, 30-50 parts of mineral oil, 3-5 parts of paraffin, 1-2 parts of zinc oxide, 2-8 parts of an accelerator, and 10-20 parts of a functional additive. The prefabricated sports field surface material prepared by the preparation method has good wear resistance, sulfur vulcanizationis not needed, and the preparation process is environmentally friendly.

Description

technical field [0001] The invention relates to the field of sports equipment, in particular to a prefabricated sports field surface layer material and a preparation method thereof. Background technique [0002] At present, there are two types of stadium plastic surfaces that are widely used, one is on-site material processing and paving; the other is prefabricated roll materials to on-site paving. On-site ingredient processing and paving has defects such as inconsistent resilience, inconsistent adhesion, poor predictability, severe weather and seasonal influences, long construction period, long waiting period for putting into use, and difficult maintenance in the later period. [0003] The prefabricated rubber runway is generally divided into three layers according to the function: the surface layer, the pressure buffer bottom layer, the bonded prefabricated rubber runway roll and the adhesive layer of the runway foundation. The main function of the surface layer is to inc...
