Problems solved by technology

[0005] However, all these methods use polyetheramine as a toughening agent to achieve the purpose of internal toughening of epoxy resin by replacing part of the curing agent. Since polyetheramine cannot be introduced into epoxy materials in large quantities, it is not enough to make the epoxy resin tougher. The damping properties of oxygen-based materials change significantly

Abstract

The invention relates to a dual-component solvent-free epoxy damping adhesive for marine use and a preparation method thereof. The preparation method comprises the following steps: (1) preparing a component A: uniformly mixing epoxy resin, modified polyether amine and an active diluent while stirring, adding a defoaming agent, a dispersant and a coupling agent, further uniformly mixing while stirring, adding a flame retardant, stirring for 10 minutes, and milling twice with a three-roller mill to obtain the A component; (2) preparing a component B: uniformly stirring an epoxy curing agent, polyether amine and an accelerator to obtain the component B; and (3) preparing a coating: uniformly mixing the component A obtained in the step (1) and the component B obtained in the step (2) at a weight ratio of 100: (10-30) to obtain the product, wherein the modified polyether amine is obtained by reacting bisepoxyl epoxy resin and polyether amine. Compared with the prior art, dual-component solvent-free epoxy damping adhesive has the advantages of long pot life, stable heat release, good flame retardancy, no VOC (Volatile Organic Compounds) and good adhesion, is convenient to construct and is cured at room temperature; the material has high loss factor at room temperature and is corrosion-resistant and vibration-proof.

Description

Technical field [0001] The invention relates to a polymer-based functional material and a preparation method thereof, in particular to a two-component solvent-free epoxy damping adhesive for ships. The material has good damping performance at room temperature and is mainly suitable for ship vibration reduction The technical field of noise reduction processing. Background technique [0002] The application of damping materials is the most effective way to reduce vibration and noise in the shipbuilding industry. With the advancement of shipbuilding technology, damping materials are more and more widely used in the modern shipbuilding industry. Damping coatings can be laid on the main engine seat, the engine room front wall and the engine room floor frame, which can consume excitation energy and reduce vibration response. It can also reduce the transmission of structural noise. It can also be used for hydrofoil noise reduction of hydrofoils, submarine propellers, and ship bottom p...
