Abstract
The invention provides an environment-friendly track and field runway. The environment-friendly track and field runway is prepared from the main raw materials of 58-62% of Pvc paste resin, 35-39% of dioctyl terephthalate, 1-3% of a calcium-zinc stabilizer and 0.5-2% of azodicarbonamide. The invention further provides a preparation method of the environment-friendly track and field runway. Four substances are mainly adopted for matching, the environment-friendly track and field runway has the advantages of being good in damping effect, excellent in rebounding performance, large in adhesive force, high in spike resisting capability, good in slip resistance and wear resistance and the like and can be widely applied to pavement materials for athletic grounds, and the maintenance frequency can be reduced in application of the environment-friendly track and field runway.
Description
Technical field [0001] The invention belongs to the field of paving materials for sports fields, in particular to a paving material with Pvc paste resin, in particular to an environmentally friendly track and field track and its application. Background technique [0002] In order to adapt to the development of track and field construction in our country, to meet the needs of holding high-level track and field competitions and developing mass track and field sports, it has excellent weather resistance, pressure resistance, impact resistance, flexibility, excellent sports safety performance, non-slip, beautiful color, And it is not affected by weather conditions and other advantages, which is well received by the public. More and more people are paying attention to the standard specifications for the use of synthetic track in track and field venues, and the importance of ensuring the construction quality of track and field venues. The laid plastic track may release harmful gases to...
