Description

水性碳纤维上浆剂的制备方法
技术领域
本发明涉及一种水性碳纤维上浆剂的制备方法。
背景技术
碳纤维具备一系列优良的功能，如高比强度、耐高温、耐腐蚀、导电、传热、热膨胀系数小等。但由于碳纤维的脆性，在加工过程中，与机械的摩擦其易构成毛丝，使它的强度降低，还会影响环境，影响机械的正常运行，此外，这对树脂和纤维的界面也必然有影响。通过上浆工艺，在碳纤维表面形成一层保护层，不仅能够保护碳纤维自身，还降低了对环境的影响。
目前，碳纤维上浆剂还存在以下主要问题：（1）制备时间过长；（2）碳纤维上浆性能不足，集束性差；（3）环境适应性差，随着环境温度的提高，复合材料层间剪切强度快速下降；（3）上浆剂与碳纤维和树脂间的结合力不够。
发明内容
本发明的目的在于提供一种碳纤维水性环氧树脂上浆剂，该浆料不包含任何外加乳化剂的改性环氧树脂碳纤维上浆剂，具有具有粘度适中、粒径较小、吸水率低、乳液稳定、环保、与碳纤维结合力强，使碳纤维后道加工性能良好，形成的复合材料具有优良的力学性能和较长的使用寿命。
为了实现上述目的，本发明采用的技术方案如下：
一种水性碳纤维上浆剂的制备方法，其特征在于：包括如下生产步骤：
1）制备碳纤维水性上浆剂专用乳化剂：按质量比为1：5-10的比例，将PEG6000与环氧树脂在温度为85℃下搅拌，并滴加相当于环氧树脂重量40-50%的三氟化硼-乙醚络合物作为引发剂，制备出环氧树脂乳化剂；
2）制备丙烯酸改性环氧树脂乳液：按重量份：将79-82份的环氧树脂与3.3-3.5份的丙烯酸倒入反应釜中，搅拌速度300r/min，温度90℃，混合均匀后，将1-3份的过氧化苯甲酰加入反应釜中，反应1.5h，降低温度为75℃后，调节PH值为7，再升温至85℃，并将14-20份的环氧树脂乳化剂倒入反应釜中，搅拌速度为2500r/min，混合均匀后，将100份的水以1份/min的速度向反应釜中滴加，滴加结束后，保温15min；
3）保温后，将用偶联剂分散好的纳米粒子SiO2倒入上述反应釜，搅拌均匀，得到水性碳纤维上浆剂。
所述偶联剂为KH-550。偶联剂分散好的纳米粒子SiO2加入量为含固量的1%-5%。
本发明的有益结果在于：该浆料的制备工艺简单，制备时间短；浆料粘度适中、粒径较小、吸水率低、乳液稳定、环保、与碳纤维结合力强；浆纱与树脂材料之间的剪切强度增强，并且浆纱的耐磨性也有一定的提高。
本发明生产的水性碳纤维环氧树脂上浆剂为乳白色的液体，其有较好的水溶性，和稳定性（贮存稳定性、稀释稳定性、离心稳定性），其含固率在50%左右，其粘度（稀释为4%）在4-5mPa.s，膜表面光滑耐磨、柔软，其膜的吸水率低；浆纱具有良好的集束性、良好的耐磨性、有适当的硬度，并且与树脂形成的复合材料有较好的结合力。
下面结合实施例对本发明作进一步说明。
