Description

一种热塑性聚烯烃浴室防水膜及其制备方法
技术领域
本发明涉及防水卷材领域，具体地说，涉及一种热塑性聚烯烃浴室防水膜的制备方法。
背景技术
防水膜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。
浴室是人们日常生活中不可缺少的场所之一，而浴室防水如果做不好，那么会大大缩短浴室的寿命，而浴室由于其自身的特点，导致浴室的防水方式单一，即一般在浴室内部的墙面上粘贴防水卷材，由于浴室多为水蒸汽，故普通的沥青防水卷材很容易失去作用，防水效果差。
发明内容
本发明要解决的技术问题是克服上述缺陷，提供一种防水效果好的热塑性聚烯烃浴室防水膜，以及制备该防水膜的制备方法，其制备方法具有制作简单、无污染、无其它杂质生成的特点。
为解决上述问题，本发明所采用的技术方案是：
一种热塑性聚烯烃浴室防水膜，其特征在于，所述防水膜由以下重量百分比的材料制成：
TPV35％、SEBS30％、MLLDPE树脂30％、钛白粉3％、杀菌剂1％，UV-91％。
一种热塑性聚烯烃浴室防水膜的制备方法，其特征在于，所述方法包括以下步骤：
(1)配料，按重量百分比选取材料；
(2)将材料放入混合机中充分混合；
(3)材料充分混合后，被混合机挤出，记录挤出时的温度；
(4)对挤出的材料进行两面覆布；
(5)覆布后的材料经三辊、冷却、卷取、成品检验、包装入库。
作为进一步的改进：
所述步骤(4)中所用的布为丙纶布。
其中，TPV为热塑性硫化橡胶，即Thermoplastic Vulcanizate的简称，又称聚烯烃合金热塑性弹性体，TPV主要由二部分组成，一是塑料，作为连续相，二是橡胶作为分散相。通常橡胶需要与软化油或增塑剂与之配合。硫化剂和一些辅助助剂也是必不可少的。另外为了降低成本或者提高某方面的性能，一些无机填料会被填加。
SEBS是饱和烃类苯乙烯嵌段共聚物(Kraton G1657)，即M苯乙烯-乙烯-丁烯-苯乙烯嵌段共聚物，SEBS不含不饱和双键，因此具有良好的稳定性和耐老化性，SEBS具有优异的耐老化性能，既具有可塑性，又具有高弹性，无需硫化即可加工使用，边角料可重使用，广泛用于生产高档弹性体、塑料改性、胶粘剂、润滑油增粘剂、电线电缆的填充料和护套料等。
SEBS具有良好的耐候性、耐热性、耐压缩变形性和优异的力学性能：
(1)较好的耐温性能，其脆化温度≤-60℃，最高使用温度达到149℃，在氧气气氛下其分解温度大于270℃。
(2)优异的耐老化性能，在人工加速老化箱中老化一星期其性能的下降率小于10％，臭氧老化(38℃)100小时其性能下降小于10％。
(3)优良的电性能，其介电常数在一千赫为1.3*10-4,一兆赫为2.3*10-4；体积电阻是一分钟9*1016Ω/cm；二分钟为2*1017Ω/cm。
(4)良好的溶解性能、共混性能和优异的充油性，能溶于许多常用溶剂中，其溶解度参数在7.2～9.6之间，能与多种聚合物共混，能用橡胶工业常用的油类进行充油，如白油或环烷油。
(5)无需硫化即可使用的弹性体，加工性能与SBS类似，边角料可重复使用，符合环保要求，无毒，符合FDA要求。
(6)比重较轻，约为0.91，同样的重量可生产出更多体积的产品。
UV-9一种紫外线吸收剂，学名叫2-羟基-4-甲氧基二苯甲酮，适用于多种塑料及合成橡胶、涂料作光稳定剂。
由于采用了上述技术方案，本发明具有以下特点：
1、良好的弹性和耐压缩变形性，耐环境、耐老化性相当于三元乙丙橡胶，同时其耐油耐溶剂性能与通用型氯丁橡胶不相上下。
2、应用温度范围广(-60-150℃)，软硬度应用范围广(25A-54D)，易染色的优点大大提高了制品设计的自由度。
3、优良的加工性能：可用注射、挤出等热塑性塑料的加工方法加工，高效、简单易行，无需增添设备，流动性高、收缩率小。
4、绿色环保，可回收使用，且反复使用六次性能无明显下降，符合欧盟环保要求。
5、比重轻(0.90-0.97)，外观质量均匀，表面档次高，手感好。
本发明所述的热塑性聚烯烃浴室防水膜具有适应范围广，耐候性，抗酸性，抗变形，使用寿命长，拉伸强度高，延伸率大。对基层收缩和开裂变形适应性强，使用温度范围宽《-40度---100度》等优点，防水、防腐性能优越。
具体实施方式
实施例1：一种热塑性聚烯烃浴室防水膜，所述防水膜由以下重量百分比的材料制成：
TPV35％、SEBS30％、MLLDPE树脂30％、钛白粉3％、杀菌剂1％，UV-91％。
实施例2：一种热塑性聚烯烃浴室防水膜的制备方法，所述方法包括以下步骤：
