一种植物油基软骨仿生缓冲减震材料及其制备方法与应用
摘要：
本发明属于缓冲减震材料的技术领域，公开了一种植物油基软骨仿生缓冲减震材料及其制备方法与应用。所述植物油基软骨仿生缓冲减震材料，由预混料A和异氰酸酯混合物B制备而成；所述预混料A包括植物油基改性多元醇、聚醚多元醇1型、聚醚多元醇2型、聚合物多元醇、表面活性剂、发泡剂、扩链剂、催化剂以及泡孔调节剂；所述聚醚多元醇1型为分子量为400～1000，羟值为110～280mgKOH/g的聚醚多元醇；所述聚醚多元醇2型为分子量为1000～10000，羟值为25～56mgKOH/g的聚醚多元醇。本发明的材料环保，具有高缓冲效果，开孔透气，永久变形率低。
摘要（英）：

The present invention belongs to the technical field of cushioning materials. Disclosed are a vegetable oil-based cartilage bionic cushioning material, and a preparation method therefor and an application thereof. The vegetable oil-based cartilage bionic cushioning material is formed from a premix A and an isocyanate mixture B, the premix A comprising a vegetable oil-based modified polyol, a type 1 polyether polyol, a type 2 polyether polyol, a polymer polyol, a surfactant, a foaming agent, a chain extender, a catalyst and a cell regulator. The type 1 polyether polyol is a polyether polyol having a molecular weight of 400-1000 and a hydroxyl value of 110-280 mgKOH/g, and the type 2 polyether polyol is a polyether polyol having a molecular weight of 1000-10000 and a hydroxyl value of 25-56 mgKOH/g. The present material is environmentally friendly, porous and breathable, and has a high cushioning effect and a low permanent deformation rate.
