Title:
COATING MACHINE OVEN, SILICON DIOXIDE COMPOSITE THERMAL INSULATION MATERIAL AND PREPARATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/148469
Kind Code:
A1
Abstract:
Disclosed is a method for preparing a silicon dioxide composite thermal insulation material, comprising: providing a flexible base layer (S100); coating a pre-formed silicon dioxide thermal insulation layer slurry on the flexible base layer to obtain a silicon dioxide thermal insulation pre-coated layer (S200); and removing a binder between porous silicon dioxide particles and inside porous silicon dioxide tunnels in the silicon dioxide thermal insulation layer slurry to obtain a silicon dioxide composite thermal insulation material, in which the silicon dioxide thermal insulation layer slurry includes porous silicon dioxide, binder, and water (S300). Also disclosed is a silicon dioxide composite thermal insulation material, which comprises a flexible base layer and a silicon dioxide thermal insulation layer composited on the flexible base layer. Also disclosed is a coating machine oven, in which an insulation layer of the coating machine oven is prepared from the silicon dioxide composite thermal insulating material.
