Runway material as well as preparation method and application thereof
The invention belongs to the technical field of runway materials, and particularly relates to a runway material which comprises star-shaped SEBS, hydrogenated S-(B/S)-S, rubber filling oil, an inorganic filler, plastic and an anti-aging agent. The chemical formula of the star-shaped SEBS is BnY; wherein B is a hydrogenated styrene-butadiene block polymer arm or a hydrogenated styrene-butadiene-styrene block polymer arm; y is a coupling agent residue; n is 3 or 4; the hydrogenated S-(B/S)-S is a hydrogenated triblock polymer, the first block and the third block are styrene blocks, and the middle block is a butadiene and styrene random copolymerization block. The research finds that based on the cooperation of the star-shaped SEBS and the hydrogenated S-(B/S)-S, the compatibility of the inorganic filler can be improved, and the performance of the runway can be improved. The material has good compatibility and wrapping property with thermoplastic plastics and inorganic fillers, wet skid resistance and good processability at a low oil charge ratio, so that the runway has good mechanical properties and weather resistance.
本发明属于跑道材料技术领域，具体涉及一种跑道材料，包含星型SEBS、氢化S‑(B/S)‑S、橡胶填充油、无机填充料、塑料和防老剂；所述的星型SEBS的化学式为BnY；其中，B为氢化的苯乙烯‑丁二烯嵌段聚合物臂或氢化的苯乙烯‑丁二烯‑苯乙烯嵌段聚合物臂；Y为偶联剂残基；n为3或4；所述的氢化S‑(B/S)‑S为氢化的三嵌段聚合物，其中，第一嵌段和第三嵌段为苯乙烯嵌段，中间嵌段为丁二烯与苯乙烯无规共聚嵌段。本发明研究发现，基于所述的星型SEBS、氢化S‑(B/S)‑S的协同配合，能够改善无机填料的相兼容性能，改善跑道的性能。该材料具有和热塑性塑料及无机填料良好相容性和包裹性、抗湿滑性和低充油比下良好的加工性，使跑道具有良好的力学性能和耐候性。
