本发明公开了一种异味吸收型防水材料及其制备方法,属于防水材料领域,一种异味吸收型防水材料,包括TPO材料防水层,它可以实现TPO材料防水层的下端依次粘接有加强层、防腐蚀层改性沥青层和防粘纸,加强层能够大大提升材料的韧性、耐高温性能和隔层性能,防腐蚀层能够保护材料不易被腐蚀,TPO材料防水层的上端依次粘接有除臭层和耐磨层,除臭层能够吸收外界的异味气体,加强层由环氧树脂与高硅氧玻璃纤维布构成,除臭层采用两层线性低密度聚乙烯微孔膜与活性炭无纺布层粘接制成,制备方法为改性沥青层的制备,加强层的制备和材料整体的复合。
Description
技术领域
本发明涉及防水材料领域,更具体地说,涉及一种异味吸收型防水材料。
背景技术
防水材料是建筑物的围护结构要防止雨水、雪水和地下水的渗透;要防止空气中的湿气、蒸汽和其他有害气体与液体的侵蚀;分隔结构要防止给排水的渗翻。这些防渗透、渗漏和侵蚀的材料统称,防水材料品种繁多,按其主要原料分为,沥青类防水材料。以天然沥青、石油沥青和煤沥青为主要原材料,制成的沥青油毡、纸胎沥青油毡、溶剂型和水乳型沥青类或沥青橡胶类涂料、油膏,具有良好的粘结性、塑性、抗水性、防腐性和耐久性;橡胶塑料类防水材料。以氯丁橡胶、丁基橡胶、三元乙丙橡胶、聚氯乙烯、聚异丁烯和聚氨酯等原材料,可制成弹性无胎防水卷材、防水薄膜、防水涂料、涂膜材料及油膏、胶泥、止水带等密封材料,具有抗拉强度高,弹性和延伸率大,粘结性、抗水性和耐气候性好等特点,可以冷用,使用年限较长。
防水材料广泛应用于建筑的屋面、地下室、外墙、屋顶花园;室内厨卫、游泳池、蓄水池、饮水池;道路、桥梁、隧道、涵洞和地下空间;高速铁路、高速公路、地铁、城市轨道、机场;引水渠、水库、坝体、水利发电站及水处理等,需要根据据防水材料应用的场所的不同,需要给防水卷材一定的特殊性能,比如在沿海地区和高盐碱地区,因为受盐碱侵蚀,建筑物的防水工程要求比一般的建筑物防水标准更高,尤其要求防水材料要具有优异耐盐碱腐蚀性能和抗氯离子渗透性、能够长时间处于高盐碱环境中仍保持良好防水性能,能够抵抗高温和严寒。在防火等级要求高的应用场所,就要求所需防水卷材有一定的防火阻燃性能,而普通的高分子聚合物改性沥青的防火阻燃性能较差,不能达到使用要求。
在人们的日常生活中,尤其是居住在新装修的房子时,会产生各类异味,降低人们的生活质量乃至于危害人们的身体健康,目前市面上销售的家居装饰类的无纺布,很少兼具防水与吸收异味功能于一体,而且现有的沥青防水卷材拉伸强度、延伸率低、温度稳定性差,易受天气的影响、耐候性较差。
针对现有技术中的缺陷,本发明的目的是提供一种可以吸收异味还具有较高强度的防水材料,可以有效解决了现有防水卷材的存在的弊端,符合目前建筑行业的需求,具有重要意义及实用价值。
