Abstract

A hollow microbead reinforced epoxy resin material with high strength, low density and low hydroscopicity is proportionally prepared from epoxy resin, solidifying agent diluent, coupling agent and hollow microbeads through screening and pretreating hollow microbeads, proportional mixing, pregelatinizing, and microwave solidifying.

Description

technical field [0001] The invention relates to the field of materials, in particular to a hollow microsphere reinforced epoxy resin composite material and a preparation method thereof. Background technique [0002] Epoxy resin is a composite material resin matrix with excellent comprehensive properties. Hollow microspheres have the advantages of low density, high compressive strength, high resistivity, small thermal conductivity and thermal shrinkage coefficient, which are unmatched by other lightweight fillers. Hollow microspheres reinforced epoxy resin composites have attracted more and more attention because of their low density and high strength, and are widely used in machinery, light industry, aerospace, shipbuilding, construction and other fields, especially for their As a solid buoyancy material, it has become an important part of the development of modern deep diving technology. In recent years, our country has gradually carried out research work in this area and...
