Description

一种高吸音性聚氨酯汽车地毯的制备方法
技术领域
本发明属于高分子材料领域，涉及聚氨酯汽车方向盘的制备技术，具体涉及一种高吸音性聚氨酯汽车地毯的制备方法。
背景技术
汽车地毯是车辆很普遍内饰。随着人们生活水平的提升，国内汽车行业迅猛发展，中高端车辆对车辆内饰的要求越来越高，国内传统工艺制作的地毯已无法满这些车辆配件需求；而从国外进口的地毯价格昂贵。因此，国产化中高端车辆地毯的研制开发已提到当前国内汽车发展的议事日程。
发明内容
本发明的目的是提供一种工艺简单、安全环保、高吸音性能的汽车地毯的制备方法。
为实现以上目的，本发明的技术解决方案如下。
本发明提供一种高吸音性聚氨酯汽车地毯的制备方法，按照重量份数计，其原料配方如下：聚酯多元醇85～100份、聚醚多元醇3～15份、叔胺类催化剂0.1～0.3份、羟基硅油0.5～1.5份、发泡剂1.5～2.5份、扩链剂1～3份、粗MDI 15～35份、液化MDI 5～25份、纯2.4'-MDI 6～20份；该制备方法的具体步骤如下：
①A料的准备：向聚酯多元醇中，加入聚醚多元醇、叔胺类催化剂、发泡剂、羟基硅油和扩链剂，加完后在20～40℃的温度下搅拌30～40min，即得A料；
②B料的准备：将粗MDI、液化MDI和纯2.4'-MDI放在反应釜中，升温至50～60℃，搅拌30～50min，即得B料；
③原料的准备：将A料打入发泡机A组原料桶内；将B料打入发泡机B组原料桶内；
④汽车地毯的制备：将皮革平铺在模具底部，用发泡机将A料与B料在浇注机混合头的混合区混合均匀，浇注成型；脱模，对聚氨酯泡沫板切割整理，得到汽车地毯。
本发明中，按重量份数计，其原料配方如下：聚酯多元醇90～95份、聚醚多元醇5～8份、叔胺类催化剂0.15～0.25份、羟基硅油0.8～1.2份、发泡剂1.8～2.2份、扩链剂1.5～2.5份、粗MDI 25～30份、液化MDI 10～15份、纯2.4'-MDI 8～12份。
本发明中，粗MDI是一种不同官能度的多异氧酸酯混合物，其中n-0的二异氰酸酯(MDI)占混合物的50％左右，其余是3官能度平均分子量为350-420的低聚合度异氰酸酯，常温下为褐色至棕色液体。
本发明中，所述聚酯多元醇的重均分子量为6000±300。
本发明中，所述发泡剂为水。
本发明中，所述叔胺类催化剂为三乙醇胺、N,N-二甲基乙醇胺的一种或两种的的组合。
本发明中，所述扩链剂为1，4－环已二醇、丙三醇、丙二醇中的一种或几种的组合。
本发明中，所述液化MDI为氨酯改性MDI。
本发明中，步骤④中，脱模时间为10～20分钟。在试验过程中，得到证明，在该脱模时间内可以保证产品的成形性能。若时间太短产品成形不完全，时间太长影响生产效率，造成生产的成本浪费。
和现有技术相比，本发明具有以下优点：
(1)由于采用重均分子量为6000±300的聚酯多元醇作为原料，加入聚醚多元醇，在不影响地毯其他性能的前提下，提高了吸音性能；
(2)所选用的原材料常温下均为液体，便于，生产方法也非常简便；
(3)在制备方法的设计上，采取全水发泡技术，无毒环保，是一种环保型生产方法；
(4)所选用的原材料为低挥发、反应型原料，制备方法具有环保、无污染等优点。
(5)所述的高吸音性聚氨酯汽车地毯的制备方法，不但简单易行，而且安全环保，吸音性能优良，可以满足中高端汽车市场对汽车方向盘环保性能的要求。
