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%;

[0062] Sodium pyrophosphate 3%;

Abstract

The invention discloses an isolation membrane material composition for a waterproof coiled material. The isolation membrane material composition is made of the following components in weight percentage: 70% to 90% of polyvinyl alcohol; 0.5% to 90% of functional additives 10%; the dispersant is 0.5%~3%; the surfactant is 0.5%~6%; the plasticizer is 1%~6%; the rest is water; The materials commonly used in construction are used as functional additives, which improve the dissolution rate of the isolation film and the bonding force between the concrete and the waterproof membrane after pouring, and significantly improve the waterproof effect. Applying the isolation membrane material composition for waterproof coiled material provided by the present invention, the special sand-containing water-soluble isolation membrane for waterproof coiled material that does not need to be peeled off during construction can effectively reduce construction strength, reduce pollution, protect the environment, and can solve the problem of existing concrete and asphalt Problems such as weak bonding and easy detachment of coiled materials can greatly improve construction efficiency, save production and use costs, and are economical and environmentally friendly.

Description

technical field [0001] The invention belongs to the field of preparation of isolation membrane materials, and more specifically relates to an isolation membrane material composition for waterproof roll materials. Background technique [0002] At present, in the production process of waterproof membranes, an isolation film is used to prevent the adhesion of the waterproof membrane. The layer is combined with waterproof material to achieve the isolation effect. The most commonly used is PET (polyester) film. On the one hand, the waterproof membrane must be stripped of the isolation material before pouring concrete during construction, and the removed isolation film cannot be used again, which not only increases the construction workload, but also Not environmentally friendly; on the other hand, the glued layer is easy to age, which will affect the bonding effect of the waterproof layer and concrete, which is not conducive to the maintenance of the waterproof effect. In additi...
