Method for preparing reinforcing epoxy resin material capable of being fast cured at medium/low temperature

Abstract

The invention discloses a method for preparing a reinforcing epoxy resin material capable of being fast cured at medium / low temperature and belongs to the technical field of materials. The epoxy resin material is characterized in that the epoxy resin material is formed by mixing a resin component A and a curing agent component B, wherein the resin component A consists of epoxy resin and an epoxy diluent; the curing agent component B consists of a curing agent and an accelerant. The method comprises the following steps: uniformly mixing and stirring the component A and the component B, and performing vacuum defoamation treatment; pouring the components into a preheated die, heating the components under the vacuumizing condition until the components are completely cured, thus obtaining the reinforcing epoxy resin system capable of being fast cured. The problems that the epoxy resin product is high in energy consumption during high-temperature curing and the dimensional accuracy of the product is difficultly controlled are solved. The composite material prepared by the method has the advantages of being fast cured and low in manufacturing cost. The method is simple and feasible in operation; the cured product is high in strength, excellent in heat resistance and high in adhesive property and is particularly suitable for repairing and reinforcing various equipment, pipelines and other epoxy resin composite material products.
