Abstract

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.

Description

technical field [0001] The invention relates to a composite plate, in particular to a thermal insulation, insulation, heat insulation and compression resistant plate which can replace the asbestos plate. Background technique [0002] Now most of the pressure-resistant panels used for heat insulation, insulation and heat preservation are usually panels made of asbestos. Asbestos panels have been used for more than 100 years. Countries have legally or de facto banned and restricted the use of panels containing asbestos. In order to replace asbestos boards, various non-asbestos boards have been launched one after another. At present, most of the so-called non-asbestos fiber boards in China are made of sepiolite as the main material. However, sepiolite is a material symbiotic with asbestos, so it is not recognized by foreign companies and environmental protection organizations. At the same time, the performance of sepiolite products is also low, especially the leakage rate and ...
