A method for manufacturing a roll-pressed non-asbestos composite board, relating to a composite board, comprising 9 steps, the main feature is to prepare a large material layer from toluene, nitrile rubber, 244 neoprene, mineral fiber and aramid fiber; Leather prepared from toluene, nitrile rubber, 244 neoprene, zinc oxide, stearic acid, 2‑mercaptobenzothiazole, N‑phenyl‑2‑naphthylamine, talc, light calcium and mineral fibers layer; and then use the rolling method to roll the five layers of large material layer, leather material layer, support layer, leather material layer and large material layer into a composite board. Compared with the prior art, the beneficial effect of the present invention is that the composite board manufactured by the method of the present invention has the performance of heat insulation, insulation and heat preservation not inferior to asbestos boards, and at the same time, compared with other thermal insulation boards, the composite board is also It has the characteristics of compression resistance, extrusion resistance, high elasticity and good resilience. It solves the problem that the performance of the existing asbestos substitute board heat insulation material is low, and the strength cannot reach the standard.
