Abstract

The embodiment of the invention discloses a low-radioactivity background waterproof sealing adhesive tape. The waterproof sealing adhesive tape comprises the following components in parts by weight: 9-11 parts of butyl rubber, 4.5-5.5 parts of diene rubber, 30-40 parts of medium molecular weight polyisobutene, 12-18 parts of low molecular weight polyisobutene, 18-22 parts of a hydrophobic reinforcing agent, 7-8 parts of a hydrophobic filler and 7-8 parts of hydrogenated tackifying resin. The embodiment of the invention also provides a preparation method of a low-radioactivity background waterproof sealant.

Description

technical field [0001] The invention relates to the technical field of waterproof sealing tape, in particular to a low-radioactive background waterproof sealing tape and a preparation method thereof. Background technique [0002] Due to its excellent bonding strength, the waterproof sealing tape has strong adaptability to interface deformation and cracking, stable chemical properties, reliable water resistance, sealing and low temperature resistance, good followability, simple construction and operation process, and does not contain any Solvent, safety and environmental protection and other advantages, and are widely used in many fields such as construction, automobile, industry, municipal engineering, military industry and so on. [0003] There are many grades of waterproof sealing tapes in the domestic market. Commonly used raw materials include: the main raw material is a polymer based on isobutylene, the filler is calcium carbonate, clay, carbon black, white carbon black...
