Title:
PROCESSING APPARATUS FOR VACUUM HEAT-INSULATING PLATE, AEROGEL-MODIFIED POLYURETHANE FOAM THERMAL INSULATION PLATE, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/185158
Kind Code:
A1
Abstract:
Provided by the present invention are a processing apparatus for a vacuum heat-insulating plate, an aerogel-modified polyurethane foam thermal insulation plate, and a preparation method therefor. The processing apparatus comprises a first frame, a conveying mechanism disposed on the first frame, two edge-pulling mechanisms arranged as mirror images on the two sides of the conveying mechanism, two adhesive tape machines arranged as mirror images on the two sides of the conveying mechanism, and an edge-folding mechanism disposed above the conveying mechanism. The edge-pulling mechanisms, the edge-folding mechanism, and the adhesive tape machines are sequentially arranged along the conveying direction of the conveying mechanism. The processing apparatus for a vacuum heat-insulating plate can replace a manual operation mode in the existing technology, thereby saving manpower, improving efficiency, and reducing costs. The aerogel-modified polyurethane foam thermal insulation plate of the present invention comprises a polyurethane foam core and at least one thermal insulation pack, the thermal insulation pack is disposed inside of the polyurethane foam core, the polyurethane foam wraps the thermal insulation pack, and the volume ratio of the thermal insulation pack in the thermal insulation plate is 10%-90%. The thermal insulation plate of the present invention has a low heat conductivity coefficient, good thermal insulation performance, and a long service life.
