Abstract

The invention relates to an underwater epoxy adhesive and a preparation method thereof; the adhesive contains A component and B component and comprises the following components by weight percent: 15-23% of epoxy resin E-51, 15-23% of epoxy resin E-44, 6-8% of epoxy active diluent, 2-5% of flexibilizer 304 resin, 13-20% of talcum powder, 6-9% of calcium oxide, 1.5-2.0% of organic bentonite, 2-4% of titanium dioxide, 0.5-1.0% of coupling agent, 0.3-1.0% of dispersant, 0.3-1.0% of defoaming agent, 10-15% of 1085 curing agent, 5-10% of 810 curing agent and 1.5-2.2% of curing accelerator; wherein, B component comprises 1085 curing agent, 810 curing agent and curing accelerator and the remainder is A component. The preparation method comprises the following steps: separately stirring the A component and the B component to disperse evenly, adding the B component in the A component to mix evenly and obtaining the underwater epoxy adhesive. The preparation method is simple, the product brushability is good, the curing rate is fast, the bonding strength is high, and the adhesive is resistant to water and the corrosion of acid and base and can not pollute the environment. The adhesive can be widely used to bond various building materials in the water and mending the concrete crack.

Description

Technical field:

[0001] The invention relates to an epoxy adhesive and a preparation method thereof, in particular to an epoxy adhesive which can be used underwater and a preparation method thereof. Background technique:

[0002] With the development of society and economy, in the field of hydraulic construction engineering, it is required to bond various building materials in water. When repairing cracks in reservoir dams, it is required to use adhesives to bond various repair materials in water. Also in other fields, such as ships, medical treatment, aquaculture, etc., there is also a need to use adhesives in water environments. However, currently there are few epoxy resin adhesives that can be used underwater, and there are disadvantages such as poor workability, low bonding strength, and poor water resistance. Invention content:

[0003] The purpose of the present invention is to overcome the defects of the prior art, aiming at the characteristics of poor working perf...
