Problems solved by technology

[0002] At present, some building waterproof layers adopt a layered structure, mainly including a non-woven fabric layer and a woven fabric layer, with an asphalt layer between the two, and a woven fabric is used to increase the strength and tension of the material; the disadvantage of its structure is that: due to the use of Although the woven cloth layer increases the strength, it is prone to water seepage, and the material is easily deformed after being exposed to the sun for a long time; the production process is more complicated if the asphalt layer is used, and the requirements for production equipment are relatively high

Embodiment 1

[0014] Example 1; such as figure 1 As shown, this kind of building waterproof layer mainly includes a PVC layer 1 and a woven cloth layer 2, and a glue layer 3 for compounding is provided between the PVC layer 1 and the woven cloth layer 2. The PVC layer 1 is made of soft foamed PVC, and the glue layer 3 is made of polyurethane glue.

[0015] The specific production process: through the dry-wet laminating machine, the PVC layer 1, the glue layer 3 and the woven cloth layer 2 are compounded together. After the compounding is completed, it is placed in an oven at a temperature of 40-60 degrees for about 48 hours, and the glue is completely After volatilization, it is measured into rolls through trimming, storage, measurement and winding processes.

Embodiment 2

[0016] Example 2: Such as figure 2 As shown, the difference from Embodiment 1 is that the woven fabric layer 2 is coated before being compounded. There is a first film layer 4 on the composite surface of the woven fabric layer 2 to form a coated woven fabric layer. The film layer 4 adopts a PE film or a PP film.

Abstract

The invention relates to a building waterproof layer. The building waterproof layer comprises a PVC layer and a woven cloth layer. A glue layer for compounding is arranged between the PVC layer and the woven cloth layer. The compounded surface of the woven cloth layer is provided with a first film layer so that a coated woven cloth layer is formed. The PVC layer comprises flexible foam PVC so that elasticity and strength of the waterproof layer are improved. The glue layer comprises polyurethane glue or other glue. The first film layer comprises a PE film, a PP film or other plastic film. The PVC layer and the woven cloth layer are creatively compounded through glue and the compounded surface of the woven cloth is subjected to film coating so that the film is formed. The building waterproof layer can well prevent water leakage and moisture and resist a high temperature of about 50-300 DEG C and has high longitudinal and transverse tension and tear strength. A detection result shows that longitudinal and transverse tension strength of the product is in a range of 100-500N and longitudinal and transverse tear strength of the product is in a range of 2000-6000gf.

Description

Technical field [0001] The invention relates to a waterproof material used in the construction field, in particular to a building waterproof layer. Background technique [0002] At present, some building waterproof layers adopt a layered structure, which mainly includes a non-woven fabric layer and a woven fabric layer. There is an asphalt layer between the two. The woven fabric is used to increase the strength and tension of the material; the disadvantage of its structure lies in: Although the woven fabric layer has increased strength, it is easy to seep water, and the material is easily deformed after a long time in the sun; if the asphalt layer is used, the production process is more complicated and the requirements for production equipment are relatively high. Summary of the invention [0003] The present invention aims to solve the above-mentioned shortcomings of the prior art and provide a building waterproof layer with high strength and good waterproof performance.
