Description
技术领域
本发明涉及防水卷材技术领域,具体涉及一种防霉防水卷材及制备方法。
背景技术
防水卷材主要是用于建筑墙体、屋面、以及隧道、公路、垃圾填埋场等处,起到抵御外界雨水、地下水渗漏的一种可卷曲成卷状的柔性建材产品,作为工程基础与建筑物之间无渗漏连接,是整个工程防水的第一道屏障,对整个工程起着至关重要的作用。产品主要有沥青防水卷材和高分子防水卷材。目前对卷材的利用主要体现的防水性能上,如果材料既要防水,还要增加其他特殊性能,这样会导致材料重量太重无法利用在许多建筑上,比如屋面的材料。同时生产困难,增加了造价成本。
目前,建筑结构中的湿积累及其引发的霉菌生长,对建筑结构的使用性能和居住环境构成着巨大的威胁。由于霉菌生长,墙体表面常常呈现红色、黄色或黑色的污点,墙体表面或墙角腐蚀,装饰层脱落,同时建筑材料***、粉化、保温材料性能降低等。霉菌的存在影响建筑美观的同时,对建筑的使用年限造成破坏,同时,当霉菌中的孢子粉进入人体的呼吸***后会迅速繁殖,轻者食欲不振、呼吸困难、双眼红肿、咳嗽、感冒,严重时,可能导致呼吸窒息。而传统装修中,家里多采用壁纸、乳胶漆来装修,不但不环保,还为霉菌的生长创造了条件。因此,将防水卷材应用于室内装修,来避免霉菌的滋生具有重要意义,但是,现有的防水卷材中,大多以防水性能为主,具有防霉效果的防水卷材未有报道。
因此,研究开发一种既具有较好的防水效果,又具有较好的防霉除菌效果的防水卷材成为目前研究的重点,符合目前市场的需求,也具有较好的应用前景及使用价值。
发明内容
针对现有技术中的缺陷,本发明的目的是提供一种防霉防水卷材及制备方法,所述防霉防水卷材不仅具有较好的防水效果,还具有优异的防霉除菌效果,能够有效避免室内因潮湿等原因导致的霉菌滋生,为人们的健康生活提供了保障,此外,所述制备方法简单易行,具有较好的应用价值。
本发明解决技术问题采用如下技术方案:
本发明涉及一种防霉防水卷材,包括基材层,所述基材层为玻纤毡层,还包括设置在玻纤毡层上表面的第一防霉层,所述第一防霉层上表面设有第一自粘防水层,所述玻纤毡下表面设有第二自粘防水层,所述第二自粘防水层下表面设有第二防霉层,所述第二防霉层下表面设有离型层,其中所述玻纤毡层与第一防霉层以及第二防霉层与离型层之间均通过粘结层连接。
优选地,所述第一防霉层和第二防霉层均包括填充料和泡沫层,所述填充料填充在泡沫层中。
优选地,所述填充料为炭黑或者页岩硅藻泥,不仅能够除去室内不良气味,还能有效防止霉菌滋生,为防水卷材的防霉除菌作用提供基础。
优选地,所述泡沫层为EVA发泡层或者酚醛树脂发泡层,具有多孔结构,两种发泡结构均具有质轻、多孔均匀的特点,不仅减轻了防水板材的整体重量,也为填充料的填充提供了场所。
优选地,所述泡沫层多孔结构的孔径为3~6mm。
优选地,所述粘结层为石墨烯改性EVA泡沫胶水层,石墨烯的改性作用不仅加强了EVA泡沫胶水的粘结性能,还使得粘结层具有较好的防水侵蚀作用。
优选地,所述第一自粘防水层和第二自粘防水层均为石墨烯改性环氧树脂层,在石墨烯的改性作用下,环氧树脂不仅具有较好的自粘性能,还具有优异的防水防腐作用,为防水卷材的防水效果提供了保障。
优选地,所述离型层为PE膜,可以保护在防水卷材不使用状态时第二防霉层与胶粘剂层不受污染,避免由于胶粘剂被污染而失去粘性。
本发明还涉及一种防霉防水卷材的制备方法,包括如下步骤:
在玻纤毡上表面涂覆一层石墨烯改性EVA泡沫胶水粘结层,然后在粘结层上表面粘结第一防霉层,第一防霉层的厚度为0.6~1.0 mm,再在第一防霉层上表面涂覆石墨烯改性环氧树脂层,改性环氧树脂层厚度为0.4~0.6mm;玻纤毡下表面涂覆石墨烯改性环氧树脂层,厚度为0.4~0.6mm,再在环氧树脂层的下表面粘结第二防霉层,第二防霉层的厚度为0.5~0.8 mm,然后在第二防霉层的下表面涂覆胶水粘结层,再粘结PE保护膜,即得所述防霉防水卷材。
与现有技术相比,本发明具有如下的有益效果:
(1)本发明所述的防霉防水卷材,采用双重防霉层和双重防水层,使得防水卷材具有较好的防水效果的同时具有优异的防霉除菌效果,能够有效避免室内因潮湿等原因导致的霉菌滋生,为人们的健康生活提供了保障,符合环境友好型产品的要求。
(2)本发明所述防霉层采用填充层和泡沫层联合使用,不仅能够充分发挥填充料的防霉除菌作用,还使得整个防水卷材由于泡沫层独特的多孔结构及特性而具有质轻、高弹、搬运方便的特性,为防水卷材的应用提供了方便。
(3)本发明所述的防水卷材还采用石墨烯改性环氧树脂作为自粘防水层,由于石墨烯具有片层共轭结构,层层叠加形成致密的隔绝层,形成致密的物理隔绝层,使得改性后的环氧树脂不仅具有较好的自粘性能,还具有优异的防水防腐作用,为防水卷材的防水效果提供了第一保障;此外,由于防水层的自粘作用可以与其他层直接粘结,为防水卷材的制备提供方便。
(4)粘结剂层采用石墨烯改性EVA泡沫胶水层,由于石墨烯的独特结构,使得改性的EVA泡沫胶水不仅具有较强的粘结牢固性,增强保护膜各层之间的粘结牢固性,避免了因粘结不牢导致的翘起、脱胶现象,为防水卷材的长效使用提供保障。此外,由于石墨烯的存在,还使得粘结层具有较好的防水侵蚀的作用,为防水卷材的防水效果提供保障。
(5)综上所述,本发明所述的防水卷材具有较好的防水、防霉效果,符合目前市场需求;此外,所述制备方法简单,操作方便,具有较好的应用前景。
