Description
Technical Field
The utility model relates to a composite film for waterproof coiled materials; belongs to the field of building materials.
Background
Nowadays, a waterproof coiled material is a commonly used building material in building construction, and in the construction of roads, bridges, roofs or other buildings needing waterproof, the waterproof coiled material needs to be paved in advance, and the common waterproof coiled material needs to be firstly subjected to base layer treatment during construction, so that the base layer is required to be solid and flat without accumulated water, the water content of the base layer needs to be lower, or a base layer treating agent is coated, so that the existing composite membrane coiled material has low tensile strength, is easy to age, has poor heat resistance and low-temperature flexibility, is easy to fracture, deform and the like, can leak water, seriously influences the use effect and the service life of the waterproof coiled material, and causes the quality problem of waterproof engineering.
