Since the 1990s, a new field of research in high-tech materials, environmental materials. The environment material requirements of traditional materials with better environmental adaptability, and also include direct materials to improve the environment. The typical environment material is characterized by its advanced nature, and the environment as well as comfort. Developed by Japan Aomori industrial experiment Field woodceramics fully equipped with the three major characteristics of a typical material. Wood ceramic is a wood (or other wood material) impregnated with a thermosetting resin after the vacuum (or nitrogen protection) carbonation of a new type of porous carbon material, wherein the wooden material after sintering to form a soft, amorphous carbon, the resin generates hard glass carbon. , Wood ceramics research there are still many problems: a single species, the use of logs is not conducive to environmental protection, very little wheat straw and other plant residues; technical route is relatively simple, but also too much limited to dipping molding; woodceramics mechanics poor performance, especially low bending strength, greatly restricted wood ceramic applications. With the Preparation of woodceramics of wheat straw and other plant residues, further development of new types of environmental materials, while achieving solid waste resource to improve the preparation process, and cause people are increasingly being combined with other materials to improve and strengthen the strength of the wood ceramic interest and attention, new materials science research in recent years, one of the hot paper straw, bagasse as raw materials, phenolic resin, carboxymethyl cellulose binder, mixed by hot-pressing sintering process Preparation of woodceramics experiment prepared material under various temperature points, and the performance of its density, porosity, strength, resistivity test system analysis and research, its performance characteristics, formation mechanism and rules of conduct preliminary clear the ratio of raw materials, phenolic resin concentration, temperature, and other parameters of the entire preparation process and wood ceramic performance. Experimental results show with wheat straw or bagasse, the Preparation of woodceramics the feasibility of the process, and also that the binder and sintering temperature on woodceramics performance impact experiments opened up a new use of straw, bagasse and other plant residues way for woodceramics research has opened up a new direction and space. Papers the traditional heating mode has been improved, the experiment and analysis of the impact of the heating mode wood ceramic residual carbon ratio, density, porosity, flexural strength, resistivity and other properties. The results indicate that to reduce the heating rate and sintering, the true density of the wood ceramics incubated at critical temperature points, porosity, flexural strength was improved, the resistivity decreased slightly, especially the residual carbon rate increased significantly. The papers selected zinc chloride, potassium carbonate, phosphate dibasic ammonia, borax chemical additives for wood ceramic raw materials, experimental and sub-Xin impact of chemical additives of wood ceramic carbon residue rate and flexural strength performance. The results show that, compared with the control group, add the right amount of chemical additives, two heating mode, wooden ceramic carbon residue rate increased by about 6% and 10%, while the bending strength, density, apparent porosity and resistivity performance was not affected, have a good effect of zinc chloride, potassium carbonate, dipotassium hydrogen phosphate ammonia and borax, etc. of chemical additives on the residual carbon ratio of the woodceramics improve. The paper further was prepared from wheat straw, bagasse and attapulgite attapulgite modified wood ceramic material, and to test the performance of the true density, bulk density, apparent porosity, bending strength, resistivity, its formation mechanism and laws. The results prove that the the attapulgite good modified 700-800 ℃ under the protection of the atmosphere, especially the green body sintering can greatly improve the strength of the traditional wooden ceramic does not affect the wood ceramic resistivity.
