Problems solved by technology

However, these methods often have one or several fatal flaws, and cannot be widely used in the field of ships. For example, the epoxy materials prepared by some methods have poor damping performance, and the composite loss factor of the material is low, which cannot meet the requirements of practical applications; Although the epoxy material has high damping performance, due to the use of expensive raw materials or the use of special production processes, the product cost is too high and the product loses its competitiveness, so it cannot be practically applied; the epoxy material prepared by some methods although It has good damping performance, but it often has defects in one or more properties such as flame retardancy, construction, curing and adhesion, and cannot meet the actual shipping requirements

Abstract

The invention relates to solvent-free double-component boat epoxy glue and a preparation method thereof. The method comprises the following steps: (1) preparation of a component A: stirring and uniformly mixing epoxy resin, modified nitrile rubber and an active diluting agent, adding a defoaing agent and a dispersant, further uniformly stirring again, adding a flame retardant, stirring for 10 minutes and grinding twice by using a three-roller machine to obtain the component A; (2) preparation of a component B: uniformly stirring an epoxy curing agent, amino-terminated liquid nitrile rubber and an accelerator to obtain the component A; (3) preparation of an epoxy material: uniformly mixing the component A obtained in the step (1) with the component B obtained in the step (2) according to a weight ratio of 100:(20-60) to obtain the epoxy material. The modified nitrile rubber is prepared from double-epoxy epoxy resin and nitrile rubber by means of reaction. Compared with the prior art, the solvent-free double-component boat epoxy glue disclosed by the invention is convenient for construction, long in service life, mild in heat emission, good in flame retardant property, high in material loss factor, free of VOC, hardenable at room temperature, good in adhesion property, resistant to corrosion and vibration and the like.

Description

technical field [0001] The invention relates to a polymer-based functional material and a preparation method thereof, in particular to a solvent-free two-component marine epoxy adhesive. The material has good damping performance at room temperature and is mainly suitable for reducing the The technical field of vibration and noise reduction processing. Background technique [0002] According to the "Noise Level Regulations on Ships" proposed by the International Maritime Organization (IMO), a large number of damping materials must be used in ships to slow down the vibration of the sound source on the steel plate to meet the sound insulation requirements between living spaces. The rules specify the noise level limits for different places, including the weighted sound insulation index of 35 from the living room to the living room, and the weighted sound insulation index of restaurants, entertainment rooms, public places and from the entertainment area to the living room and me...
