Title:
VISCOELASTIC ANTI-CORROSIVE UNDERWATER ADHESIVE, PREPARATION METHOD THEREFOR, AND VISCOELASTIC ANTI-CORROSIVE UNDERWATER ADHESIVE TAPE
Document Type and Number:
WIPO Patent Application WO/2023/051792
Kind Code:
A1
Abstract:
Disclosed are a viscoelastic anti-corrosive underwater adhesive, a preparation method therefor and a viscoelastic anti-corrosive underwater adhesive tape, which relate to the technical field of underwater corrosion prevention. The viscoelastic anti-corrosive underwater adhesive comprises: 20 to 35 parts of polyisobutylene with medium molecular weights, 8 to 15 parts of a hydrocarbon compound, 20 to 35 parts of bentonite, 10 to 20 parts of silicate, 10 to 20 parts of an inorganic filler and 0 to 2 parts of an anti-aging agent. The viscoelastic anti-corrosion underwater adhesive has high shear and peel strength, and is resistant to water, corrosion and aging. The viscoelastic anti-corrosive underwater adhesive has good shear and peel strength and water resistance, can realize water-conducting operations when the surface of the base material is wet or immersed under water, coheres well with the surface of the base material, thoroughly isolates air and moisture, and prevents corrosion.
