Embodiment 1

[0061] Prepare the following raw materials for the preparation of the asphalt waterproof membrane material with the isolation membrane material in the following weight percentages:

[0062] Polyvinyl alcohol 17-88 85%;

[0063] Quartz sand (300 mesh) 5%;

[0064] Sodium hexametaphosphate 2%;

[0065] Sodium Lauryl Sulfate 1%;

[0066] Glycerol 3%;

[0067] The rest is water.

[0068] 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.

Embodiment 2

[0070] Others are the same as in Example 1, the difference is that the raw materials and percentages of the isolation membrane material for the asphalt waterproof coiled material are as follows:

[0071] Polyvinyl alcohol 17-88 90%;

[0072] Quartz sand (600 mesh) 2.5%;

[0073] Sodium tripolyphosphate 1.5%;

[0074] Sodium Lauryl Sulfate 1.5%;

[0075] Glycerol 1%;

[0076] The rest is water.

Embodiment 3

[0078] Others are the same as in Example 1, the difference is that the raw materials and percentages of the isolation membrane material for the asphalt waterproof coiled material are as follows:

[0079] Polyvinyl alcohol 17-88 80%;

[0080] Talc powder (1000 mesh) 6%;

[0081] Sodium pyrophosphate 3%;

[0082] Sodium dodecylbenzenesulfonate 3%;

[0083] Polyethylene glycol 2%;

[0084] The rest is water.

Abstract

The invention discloses a direct burial type asphalt waterproof roll which comprises a partition layer on an upper layer and an asphalt waterproof base layer on a lower layer. The partition layer and the waterproof base layer are not combined by using an adhesive layer creatively, but a common material of the building industry is adopted as a partition layer additive, so that on one hand, the partition effect of the partition layer is improved, meanwhile the binding effect of an asphalt type waterproof layer with concrete is effectively improved, and the waterproof effect is improved; on the other hand, the preparation process procedures of the waterproof roll are greatly simplified, and production cost is reduced. By adopting the technical scheme of the invention, the direct burial type asphalt waterproof roll is simple and feasible, simple in structure, simple and convenient to construct, safe, environmentally friendly, economic, simple and stable in preparation process, low in energy consumption, and very good in industrial application prospect, the problems that concrete is not solidly adhered to a conventional asphalt roll, is liable to dissociate and the like are solved, the construction efficiency is greatly improved, and the production and use cost is reduced.

Description

technical field [0001] The invention belongs to the field of waterproof coiled materials, and more specifically relates to a direct-buried bituminous waterproof coiled material and a preparation method thereof. Background technique [0002] At present, in the production process of asphalt waterproofing membranes, in order to prevent the adhesion of the asphalt layer, a glued layer is laid on the surface first, and the isolation material is combined with the asphalt waterproof material through the glued layer 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 between the waterproof asphalt la...
