Description

一种丙烯酸酯增韧改性的PVC管材及其制备方法
技术领域
本发明涉及建筑材料,特别是涉及一种丙烯酸酯增韧改性的PVC管材及其制备方法。
技术背景
聚氯乙烯(PVC)难燃、耐磨、抗化学腐蚀、气体水汽低渗漏性好,具有优良的力学性能,PVC制品透明性、电绝缘性、隔热、消声、消震性好,是性价比优良的通用材料,在建筑领域被制成全塑窗框,得以广泛应用。但PVC材质硬、塑性差、抗冲击性及耐候性较差,属硬脆材料,尤其低温韧性差,为了在以塑代钢的时代中满足建筑行业对硬质PVC制品的需求,不断扩大高冲击强度塑料的应用范围,改善加工条件,克服PVC塑料低温脆性和对缺口敏感性的缺点,多年来,PVC增韧改性的研究相当活跃
高长全,王海燕在《高抗冲PVC管材的研究》一文中使用PVC树脂,EVA、CPE、ACR等抗冲击改性剂,有机锡稳定剂、硬脂酸钙、OPE、PE蜡、钛白粉、碳黑等原料制备了一种改性的高抗冲击PVC管材,并对其优异的物理力学性能进行测试、分析、评价。该管材具有相当高的韧性,可在较为恶劣的环境下应用,同时保留传统PVC-U管材的高设计应力。
发明内容

所述的丙烯酸酯增韧改性的PVC管材,其特征在于,其由如下步骤制备而成:
(1)将相当于钛酸丁酯重量份3-4倍的去离子水、8-10%的盐酸溶液和1/3的无水乙醇,混合均匀后,在室温下将其缓慢滴加到钛酸丁酯和剩余的无水乙醇混合液的反应器中,滴完后搅拌2-3h,再逐滴加入偶联剂KH-570,搅拌20-24h,然后加入甲基纤维素,升温至80℃反应5-8h,干燥,并用丙酮离心洗涤3次,再次干燥,即得表面接枝偶联剂的纳米TiO2
(2)在聚合釜中加入相当于氯乙烯重量份6-8倍的去离子水,脱气后,将丙烯酸(2-乙基己基)酯、氯乙烯、二辛基磺基代丁二酸酯加入预混罐进行预混,并加热到40℃,搅拌3-5h后,边搅拌边加入过氧化月桂酰,升高温度至70℃开始聚合5-8h,加入聚乙烯,继续搅拌2-3h得产物;
(3)将聚氯乙烯树脂、硬脂酸钙、表面接枝偶联剂的纳米TiO2、步骤(2)的产物,月桂酸锌加入混合机中进行混合,然后加热至75-85℃,搅拌3-4h;继续对混合机内的物料进行搅拌,并依次加入聚乙烯蜡、热稳定剂1,3-二甲基-6-氨基尿嘧啶和抗静电剂十八烷基二羟乙基甲基溴化铵进行搅拌5-8h并且加温到105-110℃后,再加入聚乙二醇搅拌2-3h后,冷却至55℃出料;将预混好的料加入到挤出机中经过熔融、塑化、混合等过程从机头连续挤出物料,即为PVC管材物料;
(4)将PVC管材物料用锥形双螺杆挤出机挤出成型,得到管坯,锥形双螺杆挤出机模头温度180-195℃;管坯挤出后经过空冷后进入水冷定径箱由定径套确定管材的外径尺寸,冷却水的温度15-20℃;管坯冷却定型后经切割成段,得到待取向管坯;
(5)将待取向管坯浸入90-98℃水浴环境中,水浴加热3-6min,使管腔内通入90-98℃的热水,用拉伸装置将管坯进行轴向拉伸,拉伸速率25-30mm/s;管坯拉伸的同时向管内腔热水施加压力,热水压力为1.6-3.0MPa,通过管坯内腔热水的压力使管坯沿径向扩胀,扩胀的同时,用定径套管来对胀大的管坯外径进行定径,定径后将管坯放在温度为10-15℃的水浴中冷却,冷却时间为3-7min,聚氯乙烯管成型为成品;
