The invention belongs to the technical field of sponges, and particularly relates to a low-hysteresis-loss sponge and application thereof. The raw material formula of the low-hysteresis-loss sponge comprises a black material and a white material, and the index range of the black material in the formula of the low-hysteresis-loss sponge is 0.9-1.1; the black material is TM8020; and the white material is prepared from the following components in parts by weight: 20 to 40 parts of grafted polyether, 60 to 80 parts of high-activity polyether, 1 to 2 parts of A cross-linking agent, 0.1 to 0.5 part of silicone oil, 0.1 to 0.6 part of A catalyst, 1.8 parts of perforated polyether and 2.6 to 3 parts of water. According to the low-hysteresis-loss sponge, the high-activity polyether and the grafted polyether serve as main raw materials, meanwhile, the open-cell polyether is matched, the open-cell polyether is polymerized through the cross-linking agent and the catalyst to form a net-shaped macromolecular structure, stability of the structure is promoted through the added silicone oil, and the obtained sponge has excellent stability, rebound resilience and compressibility; and the hysteresis factor index range of the low-hysteresis-loss sponge is 15%-20%, and the low-hysteresis-loss sponge is good in rebound resilience and high in comfort level when being applied to automobile seats.

    本发明属于海绵技术领域,具体涉及一种低滞后性损失海绵及其应用。本发明的低滞后性损失海绵,原料配方包括黑料和白料,所述低滞后性损失海绵配方中黑料指数范围为0.9‑1.1;所述黑料为TM8020;所述白料按照重量份计包括以下组分:接枝聚醚20‑40份,高活聚醚60‑80份,交联剂1‑2份,硅油0.1‑0.5份,催化剂0.1‑0.6份,开孔聚醚1.8份,水2.6‑3份。本发明的低滞后性损失海绵以高活聚醚和接枝聚醚为主要原料,同时配有开孔聚醚,通过交联剂、催化剂将其聚合,形成网状高分子结构,通过加入的硅油促进结构的稳定,得到的海绵具有优良的稳定性、回弹性和压缩性;该低滞后性损失海绵的滞后因子指标范围在15%‑20%之间,将其应用于汽车座椅回弹性好,舒适度高。
