Problems solved by technology

Ordinary SBS, APP, EVA, EPDM coils, and self-adhesive coils are poor in thermal aging and have a longer storage period. The physical and mechanical properties will decline, especially after being irradiated by ultraviolet rays from the sun. More obvious, the effect with cement mortar or post-cast concrete will be greatly reduced, and even the situation that it cannot be bonded
This results in the occurrence of flooding

Abstract

The invention relates to the technical field of waterproof coiled materials, in particular to an exposed macromolecular wet paving waterproof coiled material. The base layer of the waterproof coiled material is an exposed PVC layer, a macromolecular self-adhesive membrane is located above the exposed PVC layer, an isolation membrane is located above the macromolecular self-adhesive membrane, and the edge of the isolation membrane is connected to an edge membrane. A high density polyethylene (HDPE) sheet employed by the main body material is used as a main body layer of the coiled material, a layer of macromolecular hot melt adhesive covers the main body layer, the macromolecular hot melt adhesive is non-asphalt based and free of any solvent and plasticizer. The coiled material has very strong adhesion, good initial adhesivity and persistent adhesivity, so that the PVC can be used for exposure, and the construction bonding effects of the coiled material on different substrates can be satisfied.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled material, in particular to an exposed polymer wet-laid waterproof coiled material. Background technique [0002] In the early 20th century, foreign building waterproofing materials were mainly linoleum, and paper-based linoleum was gradually replaced by glass fiber linoleum. With the significant development of the chemical industry, especially the rubber industry, many resins and rubbers suitable for building waterproof materials have been developed and produced, which has made the research technology of building waterproof materials develop rapidly. Modified asphalt coils and polymer coils The use of materials is becoming more and more widespread. Ordinary SBS, APP, EVA, EPDM coils, and self-adhesive coils are poor in thermal aging and have a longer storage period. The physical and mechanical properties will decline, especially after being irradiated by ultraviolet rays from the sun. ...
