Preparation and characterization of palygorskite clay modified woodceramics from rape straw

In this paper, for the recycle of rape straw waste, a new technique had been adopted to prepare palygorskite clay modified woodceramics from rape straw. The composites were prepared through mixing, hotly pressing, and sintering, using rape straw and palygorskite clay as raw materials and phenolresin as adhesive. The obtained composites were characterized with different methods. The results show that the preparation of composites with rape straw, palygorskite clay and phenolresin by the proposed process is feasible. The selection of raw materials, quality ratios and sintering temperature have much effect on the technique and the properties of composites. The mechanics performance of the composites is good, when the mass ratio of rape straw to palygorskite clay is 1∶2. Also for these composites, the carbon yield is the highest at 600~700 ℃ sintering temperature, the increase of the bending strength is the best at 600~800 ℃, and the electrical conductivity is improved at 800 ℃.
