Heat insulation and fireproof unit of flame retardant wood composite was prepared with straw particles, perlite powder and inorganic adhesive as main raw materials. By adopting the orthogonal test method, and selecting the density, the straw particles dosage and the adhesive consumption as the process variables, the preparation technology of heat insulation and fireproof structure unit was studied. The testing results of variance analysis and regression analysis show that the optimal conditions were： the density of heat insulation and fireproof unit 1....
