Saline-alkaline tolerance self-adhesive waterproof coiled material and preparation method thereof

Abstract

The invention provides a saline-alkaline tolerance self-adhesive waterproof coiled material and a preparation method thereof, and relates to the technical field of waterproof materials. The coiled material comprises isolating layers, a saline-alkaline tolerance self-adhesive layer and a tread matrix layer, wherein front and back sides of the tread matrix layer are attached with saline-alkaline tolerance self-adhesive layers; the isolating layers are attached outside the saline-alkaline self-adhesive layers; the isolating layers, the saline-alkaline tolerance self-adhesive layers and the treadmatrix layers are integrally compressed and fit to form a five-layer structure; the tread matrix layer serves as a reinforcing inner rib, the isolating layers serve as outer protective layers, and thesaline-alkaline self-adhesive layers serve as saline-alkaline corrosion resistant protective layers; the saline-alkaline tolerance self-adhesive layer is prepared from the following components in percentage by mass: 5 percent of terpene resin, 20 percent of No.10 asphalt, 35 percent of No.90 asphalt, 10 percent of engine oil, 8 percent of styrene-butadiene-styrene segmented copolymer, 4 percent of saline-alkaline tolerance additives (FSA) and 18 percent of talc powder. The saline-alkaline tolerance self-adhesive waterproof coiled material can meet the requirement of priority projects for waterproofing and saline-alkaline resistance, and has the advantages of good waterproofing and alkaline resistance, high strength, simple construction and easy operation.

Description

technical field [0001] The invention relates to the technical field of waterproof materials, in particular to a saline-alkali-resistant self-adhesive waterproof roll and a preparation method thereof. Background technique [0002] At present, in construction projects, especially in waterproof projects such as high-speed railways, subways, tunnels, water conservancy projects, and basements in some coastal areas and high-salinity areas, the applicant found in the process of realizing the present invention that the salinity is too high It will cause irreversible damage to the structure of the waterproof layer, and may even cause major economic losses. The salt and alkali resistance of the waterproof membrane used in these construction projects should be no less important than the waterproof and moisture-proof performance. Since the poor salt-alkali resistance of commercially available waterproof rolls will reduce the waterproof ability of the waterproof layer, how to improve th...
