Abstract

The invention belongs to the technical field of building waterproof engineering and particularly relates to a self-adhesive waterproofing coiled material cementing material and its preparation method and a waterproofing coiled material prepared from the self-adhesive waterproofing coiled material cementing material. The self-adhesive waterproofing coiled material cementing material is prepared from 46 to 55 parts by weight of type I waterproofing coiled material asphalt, 6 to 9 parts by weight of SBS, 6 to 15 parts by weight of waste rubber powder, 8 to 12 parts by weight of aromatic oil, 5 to 10 parts by weight of tackifying resin, 4 to 9 parts by weight of ethylene bis-stearamide and 10 to 25 parts by weight of nanometer calcium carbonate. The preparation method solves the problem that the traditional method for preparing a waterproofing coiled material from SBR butadiene styrene rubber powder easily produces clustering and blocks a pipe. The processing temperature is low so that the production time of the self-adhesive waterproofing coiled material is greatly reduced and a production cost is reduced. The self-adhesive waterproofing coiled material cementing material has good waterproofing properties, high tensile strength, good extensibility, excellent low-temperature flexibility and heat resistance.

Description

technical field [0001] The invention belongs to the technical field of building waterproofing engineering, and in particular relates to a self-adhesive waterproof coiled material cement, a preparation method thereof and a waterproof coiled material prepared therefrom. Background technique [0002] With the development of the economy and the progress of the times, the requirements for building materials are getting higher and higher, and the original building materials can no longer meet the needs of the development of the times. Many buildings have lost their useful life due to water erosion. As people's requirements for the service life of buildings are getting higher and higher, people's requirements for the quality of waterproof materials are becoming more and more important. At present, the domestic elastomer (SBS) modified asphalt waterproofing membrane is still the mainstream product, especially when it is used on the exposed roof, because of its superior high tempera...
