Problems solved by technology

Among them, the modified asphalt membrane represented by SBS modified bitumen waterproof membrane has been developed rapidly as the main waterproof material in the past ten years, but the preparation price of this kind of membrane is relatively expensive, and the viscosity, elongation at break and resistance High temperature performance is poor, and does not have self-healing function
Self-adhesive waterproof membrane is a new type of high-grade waterproof material developed in recent years. It is mainly used for waterproofing the base of buildings. It has excellent flexibility and stickiness, but its tensile strength is poor, and it will break Low elongation rate, weak self-healing ability

Abstract

The invention discloses a high-temperature-resistant self-adhesive waterproofing coiled material and a preparation method thereof. The high-temperature-resistant self-adhesive waterproofing coiled material is formed by sequentially compounding five layers of an isolating membrane layer, a high-temperature-resistant self-adhesive waterproofing glue layer, a carrier film layer, the high-temperature-resistant self-adhesive waterproofing glue layer and the isolating membrane layer from top to bottom, wherein the high-temperature-resistant self-adhesive waterproofing glue is prepared from the following raw materials of epichlorohydrin rubber, a softening agent, benzotriazole-modified zinc oxide, polyformaldehyde, organic silicon elastomers for daily use, petroleum asphalt and natural asphalt; the benzotriazole-modified zinc oxide is prepared by adopting a special preparation method; the total thickness of the waterproofing coiled material is 1.5 to 5.0mm; the thickness of the carrier film layer is 1.0 to 3.5mm. The waterproofing coiled material disclosed by the invention has the advantages of excellent waterproofing property, excellent high temperature resistance and excellent ageing resistance.

Description

technical field [0001] The invention belongs to the technical field of construction engineering materials, and relates to a coiled material and a preparation method thereof, in particular to a high-temperature-resistant self-adhesive waterproof coiled material and a preparation method thereof. _ Background technique [0002] With the development of the economy and the progress of the society, various buildings have sprung up like mushrooms, but in the construction of various projects, problems such as water seepage and leakage of the roof, ground, and basement often occur. In order to solve this problem, construction Waterproof engineering came into being, and the building material widely used in building waterproof engineering is polymer waterproof membrane. Ordinary polymer waterproof materials have limited strength of the waterproof layer and anti-aging layer, and the service life is low, and the high temperature resistance, waterproof and fatigue resistance are not idea...
