Embodiment 1

[0031] The polymer self-adhesive waterproof membrane of this embodiment includes a high-density polyethylene waterproof board 1 , a self-adhesive layer 2 , a sand grain layer 4 and a limiting strip 3 .

[0032] The self-adhesive layer 2 is coated on one side of the high-density polyethylene waterproof board 1, and 500 g of adhesive is evenly coated on the surface of the high-density polyethylene waterproof board 1 per square meter. Wherein, the adhesive is composed of the following components in parts by weight: 16 parts of carbon fiber, 42 parts of SEBS, 29 parts of petroleum resin, 24 parts of naphthenic oil, 0.8 part of antioxidant, and 3 parts of calcium carbonate.

[0033] There are two limit strips 3, and the two limit strips 3 extend along the length direction of the high-density polyethylene waterproof board 1. The length direction referred to here is also the circumferential direction of the upper and lower edges of the waterproof membrane, and it is also the direction...

Embodiment 2

[0036] The difference between this embodiment and Embodiment 1 is that in this embodiment, 300 g of adhesive is evenly coated on the surface of the high-density polyethylene waterproof board per square meter. Wherein, the adhesive is composed of the following components in parts by weight: 18 parts of carbon fiber, 46 parts of SEBS, 33 parts of petroleum resin, 26 parts of naphthenic oil, 1.3 parts of antioxidant, and 5 parts of calcium carbonate.

Embodiment 3

[0038]The difference between this embodiment and Embodiment 1 is that in this embodiment, 420 g of adhesive is evenly coated on the surface of the high-density polyethylene waterproof board per square meter. Wherein, the adhesive is composed of the following components in parts by weight: 17 parts of carbon fiber, 44 parts of SEBS, 31 parts of petroleum resin, 25 parts of naphthenic oil, 1 part of antioxidant, and 4 parts of calcium carbonate.

Abstract

The invention relates to the technical field of a waterproof building material for a tunnel, and particularly relates to a high polymer self-adhesion waterproof roll and a production method of the high polymer self-adhesion waterproof roll. The high polymer self-adhesion waterproof roll comprises a high density polyethylene waterproof board, a self-adhesion layer, a sand layer and limiting strips,wherein the self-adhesion layer is coated on one side of the high density polyethylene waterproof board; the tensile shear strength of a material of the self-adhesion layer is not less than 300 Mpa/m<3> at 145 DEG C to 155 DEG C at 101.325 Kpa; the limiting strip is adhered on the self-adhesion layer, the quantity of the limiting strips is two; the two limiting strips extend in the length direction of the high density polyethylene waterproof board, are arranged in parallel, and keep a maximal scheduled distance; the sand layer is adhered on the self-adhesion layer.

Description

technical field [0001] The invention relates to the technical field of tunnel waterproof building materials, in particular to a polymer self-adhesive waterproof coiled material and a production method thereof. Background technique [0002] During the construction of the tunnel, water leakage will occur on the tunnel wall, so the waterproof membrane is used for waterproofing. When the existing waterproof coiled material is prepared, the self-adhesive layer is first attached to the waterproof board, and a layer of anti-adhesive film is covered on the self-adhesive layer, and then the anti-adhesive film is removed, and sand is covered on the self-adhesive layer, and finally rolled Forming a product, thereby causing unnecessary waste of the anti-adhesive film, increasing the flow of the production process and increasing the production cost. Contents of the invention [0003] The purpose of the present invention is to provide a polymer self-adhesive waterproof membrane, which ...
