Fast response adhesion strong crossed membrane self-adhering waterproof roll and preparation process thereof

Abstract

The invention discloses a fast response adhesion strong crossed membrane self-adhesion waterproof roll, comprising an upper cover layer, a reaction type mixed paving self-adhering gelatinous layer and a lower covering layer, wherein an overlap edge, namely an edge membrane, is arranged at the circumferential edge of the upper covering layer; the upper covering layer is strong crossed overlying polyethylene membrane, and the strong crossed overlying polyethylene membrane is formed by 45-degree crossed compound hot pressing of two layers of high-density polyethylene membranes; and the overlap edge is a silicon-coating isolating membrane, the lower covering layer is also a silicon-coating isolating membrane, and the silicon-coating isolating membrane is polyethylene glycol terephthalate silicon-coating isolating membrane. The preparation process has the advantages that the life of the waterproof roll is prolonged, the construction is more convenient, and the waterproof roll has excellent size stability and weather resistance, has performances of ultraviolet resistance and bidirectional tearing resistance, is firm in adhesion, can avoid water flow, and has good self-healing capability; and local punctured points can be automatically healed.

Description

technical field [0001] The invention relates to a self-adhesive waterproof coiled material, in particular to a self-adhesive waterproof coiled material with a CMS fast-response adhesive strength cross-membrane and a preparation process thereof, belonging to the field of self-adhesive waterproof coiled materials. Background technique [0002] At present, the common waterproof materials in my country's construction projects and various infrastructure construction projects mainly include coatings and coiled materials. The construction thickness of waterproof coating is not easy to control; it is firmly combined with the base surface, and it is easy to be affected by cracks in the base surface to cause stretching and cracking; most coatings are not easy to use in long-term water-immersed environments, and are not easy to use in places exposed to sunlight; Repeated painting, long construction period, easy to produce solvents during the construction process, polluting the environm...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above-mentioned problems, the present invention designs a self-adhesive waterproofing coiled material with a fast-response adhesive strength cross-membrane and its preparation process, which improves the problems caused by the lapped edge of the coiled material itself having no strength or adding a reinforcing layer with a small elongation during waterproofing construction. The problem of leakage improves the life of the waterproof membrane and the construction is more convenient. It solves the problem of uneven vertical and horizontal tension of ordinary cladding materials. It has excellent dimensional stability, weather resistance, UV resistance and two-way tear resistance. The problem of bonding between the coil and the base surface is solved and the bonding is firm without water; the layer has good "self-healing ability", which can make the local puncture point heal itself
