Embodiment 1

[0042] Referring to Fig. 1, a waterproof coiled material, the coiled material is a sandwich structure, the middle of the sandwich structure is an asphalt layer 1, the lower surface of the asphalt layer 1 is a fabric layer 3, and the asphalt layer 1 is covered There is a mesh layer 2, and the mesh layer 2 is covered with an auxiliary material layer 4.

[0043] The grid layer 2 is a glass fiber mesh layer. The auxiliary material layer 4 is a non-woven fabric layer, and the fabric layer 3 is a woven fabric layer.

[0044] The paving amount of the asphalt layer is 200g / m 2 ; The asphalt layer is a pure asphalt material; the laying amount of the non-woven fabric layer is 20g / m 2 , the non-woven fabric is a polyester release non-woven fabric; the laying amount of the woven cloth layer is 20g / m 2 , the woven fabric is PP woven fabric.

Embodiment 2

[0046] The basic structure of this embodiment is the same as that of Embodiment 1; the difference is that the grid layer 2 is a plastic grid layer. The paving amount of the asphalt layer is 1000g / m 2 ; The asphalt layer is a pure asphalt material; the laying amount of the non-woven fabric layer is 200g / m 2 ; Described non-woven fabric is PP non-woven fabric; The laying amount of described woven cloth layer is 200g / m 2 , the woven fabric is PE woven fabric.

Embodiment 3

[0048] The basic structure of this embodiment is the same as that of Embodiment 1; the difference is that the grid layer 2 is a wire mesh layer. The amount of paving of the asphalt layer is 400g / 2 ; The asphalt layer is a pure asphalt material; the laying amount of the non-woven fabric layer is 25g / m 2 ; The non-woven fabric is a water-based non-woven fabric; the laying amount of the woven cloth layer is 50g / m 2 , the woven fabric is polyester woven fabric.

Abstract

The composite waterproof coil is one sandwiched structure comprising one middle asphalt layer, one lower cloth layer, one net layer covering the asphalt layer, and one supplementary material layer covering the net layer. It has simple production process and low cost.

Description

(1) Technical field [0001] The invention relates to a waterproof coiled material. (2) Background technology [0002] The existing waterproof coiled material is applied to building roof waterproofing, underground waterproofing, indoor moisture-proofing, and air insulation. For example, asphalt felt, the middle layer is made of paper or non-woven fabric, and the outer two layers are made of asphalt. The disadvantages of this layered structure are: low strength, easy to absorb water and deform, easy to stick at high temperature, and short service life; [0003] The waterproof membrane also has a middle layer made of plastic or rubber, and the outer two layers are made of non-woven fabrics. This kind of structural process is more complicated and the cost is higher. [0004] For example, the Chinese patent application number is 89109312.5, and the patent name is tread rubber modified asphalt linoleum and its production process. It discloses a kind of asphalt linoleum, which has ...
