Embodiment 1
[0042] Prepare each component of the waterproof membrane material composition of the following weight percentages:
[0043] Polyvinyl alcohol 17-88 85%;
[0044] Titanium dioxide (300 mesh) 5%;
[0045] Sodium hexametaphosphate 2%;
[0046] Sodium Lauryl Sulfate 1%;
[0047] Glycerol 3%;
[0048] The rest is water.
[0049] Mix the above materials in a reaction kettle, heat to 80°C, add water and stir at the same time to make a hydrosol solution with a solid content of 12%. Isolation film, the film thickness is about 20μm.
Embodiment 2
[0051] Others are the same as in Example 1, except that the components and their percentages of the separator material composition for waterproof coiled materials are as follows:
[0052] Polyvinyl alcohol 17-88 90%;
[0053] Quartz sand (600 mesh) 2.5%;
[0054] Sodium tripolyphosphate 1.5%;
[0055] Sodium Lauryl Sulfate 1.5%;
[0056] Glycerol 1%;
[0057] The rest is water.
Embodiment 3
[0059] Others are the same as in Example 1, except that the components and their percentages of the separator material composition for waterproof coiled materials are as follows:
[0060] Polyvinyl alcohol 17-88 80%;
[0061] Talc powder (1000 mesh) 6%;
