Preparation Of Bamboo Charcoal Composite Board Material And Study On Its Property

Based on bamboo charcoal as main material which is a carbonized product of natural and renewable resource bamboo and adhesive as adhered material, bamboo charcoal composite board material having absorption and static electric resistance capability was manufactured by hot-pressing formation technology and using some reinforced measures.Firstly, in order to choose bamboo charcoal with excellent property as basic material, its microstructure and function was characterized by element analysis, FT-IR, UV and SEM. Meantime, absorption value of iodine, benzene and formaldehyde on bamboo charcoal and its volume electric resistance rate was determined. The results showed that the property of bamboo charcoal being used is better. Then, several adhesives were investigated, and the result showed PVAC emulsion is better than others as adhered material of board hot-pressing formation.In the end, PVAC emulsion-bamboo charcoal composite board was prepared by orthogonal experiment that investigated resin consumption, hot-pressing time and granularity of bamboo charcoal. The microstructure, absorption function, mechanics intensity and electric resistance rate of prepared composite board were characterized by SEM, UV, TMOEM and DT-830B DMP. The appropriate technology conditions were found out. The results showed that resin consumption was the main factor that affected all property of composite board. In order to reduce resin consumption, improve absorption ability and keep composite board better mechanics performance, the property of PVAC emulsion-bamboo charcoal composite board was investigated by blend modification of polyvinyl acetate-styrene/butene adhesive and reinforcement by flax fiber.
