Epoxy Resin Composite

In order to improve the mechanical properties of hollow glass microspheres (HGMs) reinforced epoxy resin composite, diluent was added in the system of epoxy resin. The results revealed that more HGMs can be filled in the epoxy resin when appropriate amount diluent was added in the system, thus composite with relative low bulk density 0.70g/cm3 and high compressive strength 71.85MPa was obtained. It was due to that the diluent reduce the viscosity of the epoxy resin, which ensures uniform wetting of the fillers and enables more HGMs to be filled in resin. Besides, addition of diluent improved the adhesive strength between the epoxy resin and HGMs, making the composite having a relative high specific strength and can be used in weight sensitive filed.

Modified Epoxy

According to the demand of deep-sea buoyancy material with high compression strength and low density, a novel epoxy-hollow glass microsphere composite was manufactured and characterized. Firstly, the epoxy resin is modified by chemical modification methods using poly(methyltriethoxysilane) to improve the toughness of epoxy resin. Then, the ammonium bicarbonate is used as the foaming agent to add into the epoxy resin to produce the bubbles. After mixing with a small amount of hollow glass microsphere, the modified epoxy-hollow glass microsphere composite with foams is fabricated. IR spectrum indicates that the silicone has been successfully grafted on the epoxy resin chain, which benefits the toughness of the resin. It can be found that a lot of smaller bubbles exist on the surface of hollow glass microsphere by SEM, which further reduces the density of the modified epoxy-hollow glass microsphere composite. The compression strength has been significantly improved since the bubbles on the surface of glass beads play the role of a buffer balloon and there are few air bubbles in the resin matrix. The coefficient of water absorption for the modified epoxy-hollow glass microsphere composite also increased. The flexural strength of the modified epoxy-hollow glass microsphere composite was slightly reduced at the same time. The results here confirm a promising method for buoyancy materials to promote the compression strength and reduce the density.

A novel epoxy resin (EP)/hollow glass microsphere modified (g-HGM) composite was successfully prepared. Studies showed that the water absorption rate of the g-HGMs/EP composite is lower than pure HGMs/EP and HGMs-KH550/EP composites, while the compressive strength of g-HGMs/EP composites could be increased. The enhanced interfacial adhesion between EP and g-HGMs played an important role to improve the compatibility of the two components. The g-HGMs show little effect on density (relative to HGMs) on the g-HGMs/EP composites, which can perform better than the HGMs/EP composites being used in marine environments. It was found that the optimal content of 4,4’-diphenylmethane diisocyanate in the epoxy component was 20 wt%.
