Abstract

The invention discloses a multi-function ship bottom sealant with good adhesive force and a production method thereof, and aims to provide the multi-function ship bottom sealant with good toughness and a stable structure and the production method thereof; the multi-function ship bottom sealant includes 12-25 parts of high pressure naphthenic rubber oil, 15-30 parts of solution polymerized butadiene styrene rubber (S-SBR), 20-35 parts of bisphenol A epoxy resin, 5-15 parts of brominated polybutadiene (PB) glue solution, 18-35 parts of hydrogenated rosin resin, 5-8 parts of silica and 0.2 part of an antioxidant; the multi-function ship bottom sealant has the advantages of good toughness, sterilization, more stable structure, strong adhesive force, alkali resistance and the like.

Description

technical field [0001] The invention relates to a sealant, in particular to a multi-functional sealant for ship bottom with good cohesive force and a production method thereof. Background technique [0002] Sealant is a kind of sealing material with certain viscosity, which has the functions of anti-leakage, waterproof, anti-vibration, sound insulation and heat insulation. The existing sealant for ship bottom has poor toughness, unstable structure, easy to breed microorganisms, and easy to fall off after impact, which affects the use of sealant. Contents of the invention [0003] The purpose of the present invention is to provide a kind of good toughness, stable structure multifunctional sealant for ship bottom and its production method in order to solve the deficiencies of the above-mentioned technologies. [0004] In order to achieve the above-mentioned purpose, a kind of multifunctional ship bottom sealant designed by the present invention comprises 12 to 25 parts of h...
