Embodiment 1

[0026] The plastic formula is as follows:

[0027]

[0028] The structure of the two-double bond functional group cross-linking agent containing trithioester is as follows (R 1 for H, R 2 for H):

[0029]

[0030] After mixing the above formulas, a 30mm thick rubber mat was prepared by an extrusion calender (XY-2I type, Dalian Huahan Rubber & Plastic Machinery Co., Ltd.), and the performance test was performed after one week.

Embodiment 2

[0032] The plastic formula is as follows:

[0033]

[0034]

[0035] The structure of the two-double bond functional group cross-linking agent containing trithioester is as follows (R 1 for CH 3 , R 2 for CH 3 ):

[0036]

[0037] After mixing the above formulas, a 30mm thick rubber mat was prepared by an extrusion calender (XY-2I type, Dalian Huahan Rubber & Plastic Machinery Co., Ltd.), and the performance test was performed after one week.

Embodiment 3

[0039] The plastic formula is as follows:

[0040]

[0041] The structure of the two-double bond functional group cross-linking agent containing trithioester is as follows (R 1 for H, R 2 for CH 3 ):

[0042]

[0043] After mixing the above formulas, a 30mm thick rubber mat was prepared by an extrusion calender (XY-2I type, Dalian Huahan Rubber & Plastic Machinery Co., Ltd.), and the performance test was performed after one week.

[0046]

[0047] Note: The crack repair strength is considered to be cut off on the test sample, and then the fracture is completely contacted, and the tensile strength recovery rate is tested after 24 hours.

[0048] The test results in Table 1 show that, compared with the traditional plastic track, the plastic track prepared by the present invention not only meets the requirements of the natio...

Abstract

The invention provides a plastic runway with a self-repairing function to solve the problem that in the prior art, a plastic runway is prone to cracking due to stress in the using process. The plasticrunway is prepared from SBS (polystyrene-butadiene-styrene) rubber particles, a carbonotrithioate-containing cross-linking agent with two double-bond functional groups, an initiator, operating oil, an anti-aging agent, an ultraviolet stabilizer, a filling agent and a coloring agent. The components are mixed in proportion and pressed into a rubber layer with a fixed thickness by adopting an extrusion calender, and when the rubber layer is laid on a concrete bottom layer to serve as a plastic runway, the rubber layer can meet the national standard requirement and also has an excellent self-repairing function.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a plastic runway, in particular to a plastic runway with self-repairing function and a preparation method thereof. Background technique [0002] Most of the existing plastic runways are made of polyurethane. The application of polyurethane materials on runways has many advantages, such as elasticity, all-weather usability, impact absorption, economy and weather resistance. However, during the repair, renovation and reconstruction of old polyurethane runways, it was found that most of the runway damages came from external damage caused by improper use or maintenance, such as heavy pressure and sharp weapon damage. These damages were not repaired in time when they occurred, and continued to be damaged by rain, saliva, and even cigarette butts for a long time during subsequent use until permanent damage occurred and the function was lost. The introduction and improvement of the self-...
