Abstract

The invention discloses a preparation method of a hollow glass bead-modified epoxy resin composite material. The hollow glass bead-modified epoxy resin composite material is prepared by a method of adding organic montmorillonite, casting and curing in steps at a varying temperature. The method disclosed by the invention can effectively prevent separation of low-density filler, solves a phase separation problem of the composite material and realizes uniform dispersion of the hollow glass beads in a basal body. The method disclosed by the invention can eliminate air bubbles which are produced in a preparation process of the epoxy resin composite material, and can reduce internal defects of the composite material.

Description

technical field [0001] The invention belongs to the field of composite materials, and relates to a method for preparing a hollow glass microsphere modified epoxy resin composite material, in particular to a method for preparing an epoxy resin composite material without phase separation and in which hollow glass microsphere fillers are uniformly dispersed in a matrix Preparation. Background technique [0002] Epoxy resin is widely used as the matrix of composite materials because of its excellent electrical insulation, mechanical, adhesive properties, and chemical corrosion resistance. Its use as an advanced composite material has been paid more and more attention in the fields of ships, automobiles, aerospace and other fields. Hollow glass microsphere is a kind of density in 0.125 ~ 0.6g / cm 3 Inorganic silicate materials with micron particle size and hollow structure have the advantages of light weight, controllable particle size and wall thickness. Moreover, its high com...
