In the aspects of research method, we took the method of preparing sol at first and then impregnating the wood to obtain ceramic-wood composite; this method made the wood use efficiently and increased the wood's weight gain percent. The ceramic-wood composite with performances of well decay resistance, dimensional stability, effloresce resistance and high strength was obtained by importing the cymene to the net of gel as the result of co-hydroxylation between MTES and TEOS. Making use of XPS ,we found that the apex of Si2p久久丁香五月丁中文精品、O1s、C1s had evident chemical shift , which validated the existence of Si-O-C bonding.Key Words: Sol-gel, Ceramic-wood composite, Modified sol, Ecomaterials

Take DMSO swollen treatment and DEA-SO2-DMSO decrystallization treatment for example, the X-ray diffraction and the Tobolsky's intermittent stress relaxation of treated woods were determined during soaking in water, analyzed the effects of water on crystal degree and inter-cohesion of treated woods. According to these continuous relaxation curves measured in water with different temperatures, various thermodynamic quantities were obtained by using Eyring absolute rate theory, and reviewed the chemical reactions in wood which occur in different relaxation process. For the first time quantify these crosslinkings formed in the process of tensional relaxation by using the SMCIR intermittent stress relaxation way, and defined the cross-linking reaction types. In order to find out the contribute of drying to the fixation of deformation of chemically treated wood, stress relaxation of oven-dry untreated and treated wood was measured during the process of temperature elevation and descend, then analyzed the effect of temperature change on relaxation mechanism of treated oven-dry wood. According to continuous relaxation curves of oven-dry treated wood under various constant temperature, calculated the thermodynamics of relaxation process and discussed the mechanism of molecule change in wood, at the same time, also quantified these cross-linkings produced in wood by intermittent method and on the basis of which the model of molecular change during relaxation process of chemically treated was constructed.
