Description

一种TPU材料
技术领域
本发明涉及一种高分子材料,具体公开一种TPU材料。
背景技术
热塑型聚氨酯弹性体(TPU)因具有特殊的软硬段嵌段共聚物结构,具有高强度、高模量和优良的机械性能。和其他弹性体材料相比,TPU硬度范围宽,在耐磨性能、弹性和力学性能等方面具有较好的综合性能,因此在脚轮、轴套或筛板等领域得到越来越广泛的关注。TPU应用于脚轮或轴套等领域,要求其具有良好的承载能力和刚性,同时还需具有良好的回弹和耐磨性能。聚酯型TPU随着硬度的增高,TPU的拉伸强度、撕裂强度和刚性会增加,但同时TPU的弹性和断裂伸长率会降低。选用聚醚型TPU可以获得高硬度的同时维持良好的回弹性能,但是聚醚型TPU耐磨性和机械性能相对较差。专利CN 101633717 B报道了以聚四氢呋喃多元醇(PTMG)为原料合成的浇注型聚氨酯弹性体,其硬度为86~93A,回弹率大于70%,撕裂强度大于100KN/m;JP8231669报道了将PTMG掺混和MDI合成NCO含量为5~15%的预聚体,再采用醇扩链得到聚氨酯弹性体,其回弹率大于70%,硬度为70-85A,撕裂强度为63~70KN/m。
上述资料合成的聚氨酯弹性体以PTMG为原料,均获得了较高的回弹性和力学性能。但其合成产品均为浇注型聚氨酯弹性体,属于热固性聚氨酯材料,在用于加工脚轮或轴套等产品时存在操作效率低、废品率高且无法重复使用等问题。聚氨酯弹性体软段采用纯PTMG为原料,产品的力学性能、耐磨性能和刚性等存在不足。
发明内容
本发明的目的是提供一种TPU材料,具有优异的耐磨性能和刚性、优良的机械性能;本发明同时提供了TPU材料的制备方法,科学合理、简单易行、生产加工效率高。
本发明所采用的技术方案是这样的:
一种TPU材料,由如下重量百分比的原料制成:
进一步地,所述的聚合物多元醇为聚酯多元醇,数均分子量为2000。
进一步地,所述的二异氰酸酯为4,4'-二苯基甲烷二异氰酸酯、亚苯基-1,4-二异氰酸酯、萘-1,5-二异氰酸酯或二苯甲烷-3,3’-二甲氧基-4,4’-二异氰酸酯中的一种。
进一步地,所述的扩链剂为1,4-丁二醇、氢醌-双(β-羟乙基)醚或1,6-己二醇中的一种或几种。
进一步地,所述的耐磨增强剂为有机硅聚醚改性聚合物、芳烷改性聚硅氧烷或有机硅塑料润滑剂中的一种或几种。
进一步地,所述的润滑剂为硬脂酸酰、油酸酰胺、芥酸酰胺或乙撑双硬脂酸酰胺中的一种或几种。
进一步地,所述的抗氧化剂为2,6-二叔丁基-4-甲基苯酚、四[β-(3,5-二叔丁基-4-羟基苯基)丙酸]季戊四醇酯、聚(二丙二醇)苯基亚磷酸酯或4,4'-对开异丙基二苯基C12-15-醇亚磷酸酯中的一种或几种。
进一步地,所述的催化剂为有机锡类催化剂。
综上所述,由于采用上述技术方案,本发明的有益效果是:
本发明采用聚酯多元醇为原料,降低了PTMG型聚氨酯材料的高成本,同时赋予弹性体优良的机械性能。通过引入优选的复合塑料润滑剂,在较低添加量的条件下获得了优异的耐磨性能和刚性,产品耐磨耗低于28mm3,在脚轮、轴套和耐磨筛板等领域获得了广泛的应用。
