Embodiment 1
[0037] The specific process of the preparation process of the core material of the vacuum insulation panel in this embodiment is as follows:
[0038] 1. The raw materials used are composed by parts by weight: 80 parts of superfine carbon fiber; 18 parts of clay, 4.6 parts of polyester fiber, and 150 parts of water.
[0039] The monofilament diameter of the superfine carbon fiber in the raw materials used is about 3 microns, the clay is kaolin or diatomite, and the particle size of the clay is 300-1000 mesh.
[0040] 2. After mixing clay and water in proportion, clay slurry is obtained;
[0041] 3. Add ultra-fine carbon fiber and polyester fiber into the clay slurry, stir evenly to obtain a mixed slurry, and spread the mixed slurry into a rough board after being filtered, and then enter the vacuum equipment to absorb water, and remove the excess clay slurry in the mixed slurry After the material (excess clay slurry accounts for 60-80% of the total weight of the clay slurry) is...

Abstract
The invention discloses a vacuum insulation panel core material, a preparation method thereof and a vacuum insulation panel, and belongs to the field of vacuum insulation panel core materials. The core material is prepared from the following components in parts by weight: 10 to 15 parts of clay, 50 to 90 parts of superfine fibers and 0 to 8 parts of an auxiliary agent. The superfine fibers in thecore material are bonded by adopting the superfine clay, and the preferable fiber diameter is matched with the clay granularity, so that a better bonding effect can be achieved. During preparation, inthe drying process of a substrate containing the clay and the superfine fibers, the clay continuously shrinks while bonding the fibers, so that a core material formed after drying is of an open-porestructure, and the open-pore material can improve the heat-conducting property of the prepared vacuum insulation plate and improve stability. The core material is simple in composition, reasonable inproportion, low in cost and extremely easy to operate in preparation process, the production process of the vacuum insulation panel core material can be optimized, the production energy consumption isreduced, and the production cost is reduced.
Description
technical field [0001] The invention relates to the technical field of vacuum heat insulation panels, in particular to a core material of a vacuum heat insulation panel, a preparation method thereof, and a vacuum heat insulation panel. Background technique [0002] Vacuum Insulated Panel (VIP board) is a new type of high-efficiency thermal insulation material, mainly used for thermal insulation, fire prevention and flame retardant, such as refrigerators, deep-cooled freezers, medical cabinets, shipboard engineering cold storage, mine rescue cabins, Building exterior wall, interior wall insulation, etc. Based on the principle of vacuum insulation, it is composed of a core insulation material and a closed air barrier film. The filling core material closely conforms to the vacuum protection surface, which can effectively avoid heat transfer caused by air convection, and the thermal conductivity is greatly reduced, so as to achieve excellent performance. insulation effect. Cor...
