Problems solved by technology

The waterproof coiled material disclosed in the above patent application has relatively good effects in terms of structural strength and high and low temperature resistance, but the adhesive layer of both is formed by conventional coating or hot pressing, so the coiled material is Under the condition of extreme stress, the adhesive layer is difficult to separate from the substrate or the polymer film layer, so it is easy to break and cause engineering leakage

Abstract

The invention discloses a base and glue separable waterproof roll. The base and glue separable waterproof roll is of a multi-layer composite structure which comprises an isolating film, an upper adhesive layer, an upper coating film, a high-strength resin base, a lower coating film, a lower adhesive layer and an isolating film from top to bottom in sequence. The upper coating film and the lower coating film are obtained by means of a spraying technology which comprises the steps of cleaning and leveling the surface of the high-strength resin base, conducting surface treatment on the high-strength resin base with a composite treating agent, and spraying an adhesive and iron powder mixture onto the surface of the high-strength resin base subjected to surface treatment with the vacuum electrostatic spraying method. Due to the fact that the surface of the high-strength resin base is obtained by means of the spray-coating technology allowing separation of the spray-coating films and the high-strength resin base, the spray-coating films and the high-strength resin base can be separated under the action of extreme stress, so that the adhesive layers and the base are separated, and then engineering leakage caused by material cracking is avoided.

Description

technical field [0001] The invention relates to a waterproof coiled material, in particular to a waterproof coiled material capable of separating tire rubber. Background technique [0002] The waterproof membrane used for buildings plays a role in resisting external rainwater and groundwater leakage. As a non-leakage connection between the engineering foundation and the building, it is the first barrier for waterproofing the entire project and plays an important role in the entire project. important role. In the prior art, the waterproof membrane with asphalt-coated multi-layer structure has low tensile strength, poor heat resistance and low temperature flexibility, resulting in poor dimensional stability of the waterproof membrane, poor membrane bonding, and prone to breakage, deformation, etc. Phenomenon, affect the use effect and service life of waterproofing membrane, cause the quality problem of waterproofing project, at the same time, frequent maintenance will also wa...
