Problems solved by technology

At present, there are many types of flexible waterproof materials on the market, with different performances, such as petroleum, asphalt, paper tires, and linoleum. However, when used as waterproof materials, they have poor low-temperature flexibility, are easy to age, and have a short service life. A large amount of waste gas is generated during the preparation of asphalt, which pollutes the environment. Serious, prone to burns and house fire accidents

Embodiment Construction

[0015] The present invention will be specifically described below in conjunction with the accompanying drawings.

[0016] Accompanying drawing is the sectional structural drawing of PVC waterproof coiled material of the present invention.

[0017] The PVC waterproof membrane is composed of multiple layers, specifically, it is composed of a buffer layer 1, a PVC material layer 3, and a protective layer 4. The buffer layer 1 and the PVC material layer 3 are welded together by PVC gasket 2, and the protective layer is 4 points. Fixedly pasted on the PVC material layer 3. Among them, the buffer layer 1 and the protective layer 4 are high-quality polyester non-woven fabrics, which have the effect of isolation and protection, and greatly improve the anti-perforation ability of PVC coils; the special adhesive SLQ601 / SLQ801 is suitable for bonding between different base layers and different materials ; Unique Φ6.3mm high-strength screws can be directly fixed on the structural layer. ...

Abstract

The invention relates to a PVC waterproof coil material which mainly comprises a buffer layer, a PVC material layer and a protective layer. The buffer layer and the PVC material layer are welded and jointed by PVC gaskets; and the protective layer is fixedly adhered to the PVC material layer in a point mode. The PVC waterproof coiled material has the characteristics of high tensile strength, large elongation, good weather resistance, wide range of the service temperature, and the like and the advantages of cold operation, simple and convenient construction, the reduction of environment pollution, the improvement on the labor conditions, and the like, not only makes up the defects of the yield and the performance of paper base asphalt felt, but also can effectively reinforce the impermeable performance of a waterproof layer of the coiled materials, prolong the waterproof durable time of the coiled materials, improve the integral quality of the waterproof layer, ensure that the waterproof layer has higher practical value in the building waterproof engineering and has wider application prospect.

Description

technical field [0001] The invention relates to the field of building waterproof materials, in particular to a PVC waterproof coiled material. Background technique [0002] Roof leakage is a common problem in construction projects. To ensure the quality of waterproof projects, in addition to design and construction factors, appropriate waterproof materials must also be selected. At present, there are many types of flexible waterproof materials on the market, with different performances, such as petroleum, asphalt, paper tires, and linoleum. However, when used as waterproof materials, they have poor low-temperature flexibility, are easy to age, and have a short service life. A large amount of waste gas is generated during the preparation of asphalt, which pollutes the environment. Severe, prone to problems such as burns and house fire accidents. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the purpose of the present invention is t...
