Problems solved by technology

However, for the resin glue used in these special occasions, in addition to exerting its conventional bonding effect, it generally needs to have good corrosion resistance and certain wear resistance. Traditional rubber materials often do not have these properties. Therefore, the use of The pipes or equipment treated with traditional rubber materials are likely to be damaged at the joints during use, which will affect the sealing of the entire pipeline or equipment, and affect the use effect and life

Abstract

A graphene modified epoxy resin adhesive is composed of a component A and a component B, the component A is composed of bisphenol A epoxy resin, benzoxazine resin, ethylene glycol butyl ether, nano-mica powder, nano-zinc powder, an active diluent and modified graphene, and the component B is composed of diethylenetriamine and a Mannich base curing agent. The graphene modified epoxy resin adhesiveis easy to produce, can be used only by uniformly mixing the component A with the component B, is convenient to operate, has a high adhesive strength, can resist erosion of various chemical media in the using process at the adhesive position after adhesion, is wear-resistant, and can resist scouring of internal media, so that it is ensured that a pipeline or device has a long service life, the shutdown repair time of the pipeline or device is shortened, and the production cost is saved.

Description

technical field [0001] The invention relates to a graphene-modified epoxy resin glue and a preparation method thereof, which relate to an epoxy resin glue with wear resistance, strong adhesion and good corrosion resistance and a preparation method thereof, and belong to the technical field of polymer materials. Background technique [0002] In the chemical industry, thermal power generation, papermaking and other industries, a large number of pipes or equipment are often used. In addition to the traditional mechanical connection, the connection method of these pipes or equipment is to use resin glue to achieve the effect of use, and at the same time it is faster and easier. Therefore, Has been highly concerned and welcomed by the people. However, for the resin glue used in these special occasions, in addition to exerting its conventional bonding effect, it generally needs to have good corrosion resistance and certain wear resistance. Traditional rubber materials often do not...
