Seal puddle

Abstract

The invention discloses a seal puddle. The seal puddle is characterized by comprising the following raw materials in percentage by weight: 50 to 60% of butadiene rubber, 10 to 25% of polyisobutene, 5 to 8% of carbon black, 2 to 5% of ebonite, 11 to 15% of nano calcium carbonate, 5 to 10% of connection resin, 0.3 to 1% of barium sulfate, and 2 to 5% of talcum powder. The seal puddle has the advantages that the component proportion in the prescription is optimized, and the glue hardly overflows, flows and moves, is high in water resistance and seal performance, smoother in surface and high in adaptability.

Description

technical field [0001] The invention relates to a sealing glue. Used in electric power, communication, petroleum, construction, mining and other fields where waterproof, insulation and sealing are required. Background technique [0002] Ordinary cement is prone to defects such as overflow, flow, and movement, and its waterproof and sealing performance is not good. The surface of the product is also relatively rough, and its adaptability is not strong. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a sealing cement with good waterproof performance and smooth surface. [0004] The present invention is realized through the following technical solutions: a sealing cement, characterized in that it comprises the following raw materials in percentage by weight: butadiene rubber 50-60%, polyisobutylene 10-25%, carbon black 5-8%, stearin 2-5%, nano calcium carbonate 11-15%, binder resin 5-10%, barium sulfa...
