Abstract

The invention provides a high-temperature-resistant self-adhesive waterproof coiled material and a preparation method thereof, which relate to the field of building materials. It includes the following steps: uniformly mix butyl rubber and carbon black and heat it, and obtain a coarse rubber mixture after cooling; uniformly mix the crude rubber mixture and nitrile rubber, heat it, and assist it with ultrasonic waves, and after stirring, obtain a refined mixture Rubber mixing: Blend the refined rubber with light calcium carbonate, paraffin, stearic acid, filler oil, anti-ultraviolet agent, and antioxidant, put it into the extruder after blending, and the extruded product is calendered and drawn , After winding and forming, the base layer of the waterproof membrane is obtained; the refined rubber, rubber accelerator, paraffin, polyisobutylene, and talcum powder are blended to obtain the self-adhesive paste; the obtained self-adhesive paste is mixed with The base layer of the waterproof membrane is compounded, and an anti-adhesive film is set on the self-adhesive layer formed by the self-adhesive paste to obtain a high-temperature-resistant self-adhesive waterproof membrane. The invention can effectively prevent the self-adhesive layer from being detached from objects, and the self-adhesive layer and the base layer of the waterproof coiled material have strong affinity and are not easy to detach.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a high-temperature-resistant self-adhesive waterproof coiled material and a preparation method thereof. Background technique [0002] Waterproof membrane is a commonly used material in building construction. It is mainly used for waterproof construction of building roofs and underground works, and plays a vital role in resisting the leakage of rainwater and groundwater. However, the traditional waterproof membrane is not ideal in terms of high temperature resistance. When the temperature is high, the self-adhesive layer will melt slightly, which will cause the self-adhesive layer to separate from the object, and the self-adhesive layer is also easier to remove from the base layer of the waterproof membrane. fall off. [0003] Therefore, it is necessary to develop a high temperature resistant self-adhesive waterproof membrane. Contents of the invention [0004] The object of ...
