Stereoscopic colorful auto-bonded macromolecular waterproof roll

Abstract

The invention relates to a stereoscopic colorful auto-bonded macromolecular waterproof roll. The stereoscopic colorful auto-bonded macromolecular waterproof roll sequentially comprises a membrane layer, a first auto-bonded layer, a core layer, a second auto-bonded layer and a colorful mineral grain layer. The core layer is prepared by 100 parts of polyvinyl chloride resin, 15-25 parts of polyethylene terephthalate-1, 4-cyclohexane dimethanol ester, 10-20 parts of organic fibers and 3-5 parts of ABS high-adhesive powder by weight. Each auto-bonded layer is prepared by 100 parts of modified asphalt, 30-40 parts of naphthenic oil, 10-20 parts of butadiene styrene rubber, 25-35 parts of styrene thermoplastic elastomers, 20-30 parts of talcum powder, 1-2 parts of antioxidant and 3-5 parts of ultraviolet light absorber by weight.

Description

technical field [0001] The invention belongs to the technical field of building waterproofing, and in particular relates to a three-dimensional color self-adhesive polymer waterproofing coiled material. Background technique [0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis The leak-free connection with the building is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. The main products are asphalt waterproof membrane and polymer waterproof membrane.

AI Technical Summary

Problems solved by technology

[0003] Traditional modified asphalt waterproofing membranes are complicated to construct and require the use of open flames for hot-melt bonding, which produces smoke and exhaust gas, pollutes the environment, and is prone to safety accidents; it cannot be completely bonded to the base layer, and water seepage and channeling often occur phenomenon; in addition, its construction speed is slow, and it is greatly affected by weather changes, base surface flatness and moisture content, and it is easy to delay the construction period

[0004] The traditional polymer waterproof roll has a hard texture, poor construction smoothness, and due to complex equipment, poor passability during the welding process, and high difficulty in waterproof node construction, it is only suitable for large-scale simple waterproof projects.

The traditional polymer waterproof membrane is constructed by wet method, and its construction method is single, and cement slurry is used as the bonding medium for the overlapping edges between materials. At the same time, if it is affected by rainfall during the construction process, the rainwater will dilute the unset cement mortar at the edge of the lap, resulting in failure of the lap joint and complete bonding with the base layer cannot be achieved
