Description

用于低模温工艺的聚氨酯组合料及其制备方法
技术领域
本发明属于聚氨酯合成领域，具体涉及一种用于低模温工艺的聚氨酯组合料及其制备方法。
背景技术
随着经济的发展，聚氨酯高回弹发泡产品的应用也越来越广泛，对聚氨酯。传统的高回弹模塑发泡工艺，一般要求模具温度在50-70℃，才能保证较好的外观表皮和整体弹性，否则会出现脱皮、外观粗糙、开模时间延长等问题。所以制作发泡模具时，材质一般为导热较好的铝或钢，并且需要设计循环水浴电加热***，模具制造费用和能耗都比较高。其中专利文件CN200910194469涉及利用改性MDI作为B料来达到降低模温的目的，但是利用该方法有两个局限性，一是降低模温程度有限，需求温度在40-50℃；二是限定B料为全MDI体系，不能在TDI体系中应用。
发明内容
针对现有技术的不足，本发明的目的是提供一种用于低模温工艺的聚氨酯组合料，解决表面熟化问题，可在模温20℃条件下使用；本发明同时提供其制备方法，工艺合理，易于实现。
本发明所述的用于低模温工艺的聚氨酯组合料，由A组分和与B组分以质量比为A:B＝100:40-70组成，其中，
A组分由以下重量百分数的原料制成：
B组分为异氰酸酯。
其中：
A组分优选由以下重量百分数的原料制成：
B组分为异氰酸酯。
其中：
聚醚胺是官能度为2，数均分子量为500-900，主链为聚醚结构，末端活性官能团为胺基的聚合物；优选JEFFAMINE ED-600(美国亨斯曼公司)或JEFFAMINE ED-900(美国亨斯曼公司)中的一种或两种。
聚醚多元醇是以甘油为起始剂，伯羟基含量≥65％，数均分子量为4500-7000，用氧化乙烯封端的聚氧化丙烯三元醇，优选FA-703(可利亚聚醚多元醇南京有限公司)或EP-3600Y(山东蓝星东大化工有限责任公司)。
聚合物多元醇为以乙烯基聚醚三醇为基础聚醚，用苯乙烯或丙烯腈接枝共聚，固含量≥20％的高活性聚合物多元醇，优选POP3630(可利亚聚醚多元醇南京有限公司)或POP40(山东蓝星东大化工有限责任公司)。
异氰酸酯为甲苯二异氰酸酯、纯MDI、碳化二亚胺改性MDI、MDI-50、聚合MDII或NCO封端的改性MDI中的一种或多种的混合物。NCO封端的改性MDI，是MDI与聚醚多元醇预聚反应得到的，NCO的质量含量为17％-30％，NCO封端的改性MDI优选WANNATE8001(万华化学公司)或WANNATE 8019(万华化学公司)。
催化剂为低模温催化剂和叔胺类催化剂的混合物，叔胺类催化剂与低模温催化剂的质量比为0.3-1.5:0.3-0.8。低模温催化剂优选为美国空气化工公司的DC3040；叔胺类催化剂为发泡型催化剂、凝胶型催化剂、反应性催化剂或延迟性催化剂的一种或几种，优选市售的A-1、A-33、DMEA、MP601、MP602或C-225中的一种或几种。
扩链剂为乙二醇(EG)、一缩二乙二醇(DEG)、1,4-丁二醇(1,4-BG)、1,3-丙二醇(1,3-PDO)或一缩二丙二醇(DPG)中的一种或几种；交联剂为三乙醇胺(TEA)、二乙醇胺(DEOA)或甘油中的一种或几种；物理发泡剂为常压下沸点低于70℃的氟氯烃的一种或多种；泡沫稳定剂为聚硅氧烷-氧化烯烃嵌段共聚物，优选L-3150(美国GE Toshiba Silicones公司)。
所述的用于低模温工艺的聚氨酯组合料的制备方法，包括如下步骤：
A组分料：首先将聚醚多元醇、聚合物多元醇、聚醚胺投入中搅拌，然后依次加入计量好的泡沫稳定剂、交联剂、扩链剂、催化剂、水，在室温条件下，转速为30-80r/min，搅拌1-2h，即得A组分合格产品。
B组分料：将基于配方量的甲苯二异氰酸酯、纯MDI、碳化二亚胺改性MDI、MDI-50、聚合MDI、NCO封端的改性MDI依次加入到搅拌釜中，在室温条件下，转速为30-80r/min，搅拌0.5-1h即得B组分合格产品。

与现有技术相比，本发明具有以下有益效果：
(1)本发明组合料在模温20℃条件下使用时可以得到具有较好外观和整体弹性的泡沫塑料制品，所以模具材质也可选用价格较低不耐高温的树脂，而且不用设计循环水浴电加热***，在频繁更换模具或者供电不足的场所，能大大降低成本和能耗；
(2)经检测，该用于低模温工艺的聚氨酯组合料产品质量指标可以达到：
(3)本发明还提供其制备方法，工艺简单，易于实现。
