Preparation and properties of palygorskite clay modified woodceramics from bagasse/wheat straw

A new technique has been developed to prepare palygorskite clay modified woodceramics using bagasse or wheat straw as raw material and phenolresin as adhesive. The composites were prepared and some properties of palygorskite clay modified woodceramics such as density, porosity, strength and resistivity were tested at the same time. A systematic analysis of the material properties, forming mechanism and regularity of composite is made. Effects of the formula of raw materials, the consistencies of adhesive and the temperature on the technique and the properties of composite were revealed. It is shown that the bagasse and wheat straw can be used to produce palygorskite clay modified woodceramics with this technique and temperature influences the properties of composite distinctly. Sample sintered between 700-800℃ can advance strength while resistivity of woodceramics don’t change. The presented work provides useful ideas for the study of the bagasse, wheat straw and palygorskite clay.
