Abstract

The invention relates to a flexible waterproof cushion. The flexible waterproof cushion is prepared from the following raw materials by weight percent: 10-30wt% of Portland cement, 1-5wt% of concretehardening agent, 1-20wt% of strong magnetic rubber powder, 1-10wt% of fluoro resin, 1-10wt% of resin curing agent, 20-60wt% of thin sand, 1-15wt% of additive, and a proper amount of water. The flexible waterproof cushion has high flexibility, good waterproof performance, and high durability, can be used as a cushion between a steel keel structure body and a reinforced concrete strip foundation, and is used in the field of thin-walled light steel structure assembled buildings.

Description

technical field [0001] The invention relates to the field of thin-walled light steel structure prefabricated buildings, in particular to an elastic waterproof cushion and a preparation method thereof. Background technique [0002] Prefabricated buildings refer to buildings assembled on site using prefabricated parts. Including prefabricated concrete buildings, thin-walled light steel structure prefabricated buildings, modern wood structure buildings and other prefabricated buildings. It has six characteristics of standardized design, factory production, assembly construction, integrated decoration, information management and intelligent application. In the next ten years, prefabricated buildings will account for more than 30% of the new construction area. Taking a 10-year cycle, based on the average price of existing prefabricated buildings, the prefabricated construction market will reach 4.7 trillion yuan in 2025. [0003] The new steel structure prefabricated resident...
