Method for preparing spliced thermal insulation cylinder by using carbon-carbon composite material
The invention discloses a method for preparing a spliced thermal-insulation cylinder by using a carbon-carbon composite material, belongs to the technical field of thermal-insulation carbon-carbon materials, and particularly relates to a method for preparing a carbon fiber web from carbon fiber precursors, treating the carbon fiber web by using an impregnating compound containing functionalized starch, soaking in a resin glue solution, and curing by using a curing agent to obtain the spliced thermal-insulation cylinder. After the resin glue solution is completely soaked in the net tire, a carbon-carbon composite material prefabricated body is obtained through curing treatment, a carbon-carbon composite material is obtained through graphitization treatment, and then the spliced heat preservation cylinder is obtained through a splicing procedure; the functional starch in the impregnating compound is obtained by reacting 2-chloro-4, 6-diamino-1, 3, 5-triazine with starch, and the functional starch in the impregnating compound is obtained by reacting 2-chloro-4, 6-diamino-1, 3, 5-triazine with starch. The Young modulus of the prepared carbon-carbon composite material is high; the shear strength is high; the thermal insulation performance is good, and the thermal conductivity is 14-19 w * m <-1 > K <-1 >; the heat resistance is good, and the ablation weight loss ratio at the temperature of 700 DEG C is 0.04-0.05 wt%.
