One is the interstitial water or zeolitic water, it corresponds to the broad absorptive band at around 3498 cm〓 that results from the association of water owing to the H-bonding. 2 The other is the water coordinated to lanthanum, corresponding to the very strong sharp peak at 3607cm〓, The peaks at around 1600cm〓 were assigned to the bending vibrations of water in LaHCF, two sharp peaks were found at 1601cm〓 and 1624cm〓 respectively, which correspond to two bending vibrations of the interstitial water and the coordinated water respectively in the structure of LaHCF.

Firstly, the different effect of rectorite modification for the mechanical property of E-51 system were compared; the effect of organic clay for the viscosity and Gel-time of pure E-51 epoxy resin were checked separately; the influence of organic clay for hardening process was studied with FTIR technology; And, the infection of organic rectorite content in matrix for the mechanical property thermal-wet tolerance property aging resistance property and medium endure property for the both of two system were studied relatively. The effect of organization for the inter-layer distance of clay was denoted by XRD technology; To probe into the thermodynamics status about reaction, we investigated the heat discharging of reaction system in the help of DSC. The impact and crooking of solidifying system was observed with the SEM to investigate the decentralization of organic clay, and, at the base of this ,we discuss the mechanism of clay toughing-buildup polymer matrix.
