▎ 摘　　要

NOVELTY - Preparing a core material of a vacuum insulation panel, comprises (1) mixing raw glass crushed, quartz powder, Glauber's salt, graphene powder, boric acid and anhydrous borax, (2) dissolving and fiberizing the raw material to obtain glass fibers, (3) diluting the glass fiber with water and stirring for 60 minutes at 100℃ and a stirring speed of 400 revolutions/minutes, adding magnesium hydroxide, and beating and surfing the web, (4) pressing the glass fiber with a pressing roller, brushing with adhesive, and compound more than one glass fiber sheets and polyamide fiber sheets to obtain a core material blank with a thickness of 10-50 mm, (5) dehydrating the core material blank and drying at 130-200℃ for 2-7 hours, and (6) cooling to room temperature and trimming the rough edges to obtain the main body of the core material. USE - The method is useful for preparing a vacuum insulating plate core material of a stirring device i.e. stirring device, in a building heat insulating material, and powdery silicon dioxide, gas, gel fiber and microporous polyurethane. ADVANTAGE - The vacuum insulating plate core material has excellent compressive property and flame retardant property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a stirring device for manufacturing vacuum heat insulating plate core material. DESCRIPTION OF DRAWING(S) - The drawing shows of a device for preparing vacuum insulating plate core material. 1Stirring barrel 2Stirring shaft 3Soft blade 4Through hole 5First feeding port 6Upright post 7End cover 8Pull rod 9Pin shaft 10Gear 11Rack 12Telescopic cylinder 13Air pipe 14Blower
