Document Type and Number:
WIPO Patent Application WO/2021/125458
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a quasi-incombustible thermal insulation sheet, and a quasi-incombustible thermal insulation sheet manufactured thereby. A method for manufacturing a quasi-incombustible thermal insulation sheet according to the present invention comprises: a mixing step for mixing incombustible material in the form of powder, thermal insulation material in the form of microscopic hollow-sphere powder, and a cross-linking agent for coupling the incombustible material and the thermal insulation material; a stirring step for heating and stirring the mixture obtained in the mixing step; an extrusion step for extrusion-molding the mixture, obtained in the stirring step, in the form of a sheet; and a compression step for compressing the mixture, molded in the form of a sheet in the extrusion step, in the thickness direction.
