Description
技术领域
本发明涉及一种具有高支撑力的记忆海绵,属于海绵制品技术领域。
背景技术
记忆海绵,最初是为美国航空航天局为太空计划设计开发的一种高科技材料。它是为宇航员设计的,帮助缓解宇航员在起降和飞行过程中所承受的压力。记忆绵慢回弹性能产生的原因,主要是由于其有特别的微粒结构——蜂巢式构造:在显微镜下,记忆海棉最微小的单位,由细小的细胞小室组成,细胞的细胞壁致密可以包含空气,却只有微孔与外界和其它细胞连通,每个细胞构造非常均匀微孔的大小也非常的一直。与普通海绵内小单元间的气体通畅或隔绝有巨大的不同,在大气压力作用下,气体进出细胞的情况决定了记忆海绵的主要力学性能。空气被压出细胞、细胞被压扁后,虽然外力已经祛除,细胞壁也有还原的弹力,但是由于通气孔细小,空气并不能很快地回到细胞内,细胞也不能很快地恢复形状,回弹的力量被抑制,材料变形复原的时间就被延长了。由于现在工业上对于记忆海绵的需求量越来越大,对其性能也就不仅仅局限于其回弹性能,而对其承载性能也有了较高的要求,从而满足工业方面的需求,但是现在的大多数记忆海绵其主要目的是用于非工业目的,因此其支撑力性能不足。
发明内容

本发明是通过以下技术方案实现的:
一种具有高支撑力的记忆海绵,其特殊之处在于由以下按重量份配比的原料制成:聚醚多元醇混合物50-80份、聚合物多元醇10-50份、4,4`-二苯基甲烷二异氰酸酯23-48份、硅油0.4-2份、扩链剂0.3-4份、交联剂0.3-4份、催化剂0.8-5份、发泡剂1.5-3.5份;
所述的聚醚多元醇混合物为羟值为35~45mgKOH/g的多元醇和羟值为110~150mgKOH/g的多元醇的复合物;
所述的扩链剂为1,6一己二醇、三羟甲基丙烷、三甘醇复合物;
所述的交联剂为三羟甲基丙烷;
所述的催化剂为三乙烯二胺和双(二甲氨基乙基)醚的复合物;
所述的发泡剂为水;
