Embodiment Construction

[0011] The invention discloses a method for making a back-sealed vacuum insulation panel. The vacuum insulation panel includes a core material and a gas barrier film coated on the outside of the core material, and the inside is vacuumized. The feature is that:

[0012] (1) The formula of the core material: its composition and parts by weight are: take dry ultrafine silica powder 40-70, filler 0-40, inorganic core material (silica fume, aluminum silicate, perlite- Mixture of two or more kinds) 0-50, inorganic fiber 1-18, getter 0-3, vacuum stabilizer 0-2.8, mix these raw materials evenly;

[0013] (2) Use a bag making machine to make a non-woven bag of a specified size, seal three sides, and leave one side unsealed;

[0014] (3) Weighing and bagging: the core material is weighed according to the formula and poured into the non-woven bag, and the unsealed side of the non-woven bag is sealed;

[0015] (4) Lay the non-woven bag on the leveling machine in the forward direction, an...

Abstract

A preparation method and a device for a back-sealing vacuum insulation panel. A gas barrier film is tiled; a prepared core material is placed in the middle of the gas barrier film; a triangular support device is used to fold both sides of the gas barrier film into the middle of the core material, and the two sides are sealed; and a gas barrier film pocket filled with the core material is placed into a vacuum device and is vacuumized to 200Pa. The invention has the following advantages: a peripheral edging (long edge) of the vacuum insulation panel is reduced, in order to realize simpleness and reliability, and improve the production efficiency; and the vacuum insulation panel has high heat insulation performance and long vacuum-maintaining time, and can effectively avoid heat transfer caused by cross-ventilation. Therefore, the back-sealing vacuum insulation panel has substantially reduced thermal conductivity, which is less than 0.008w / m.K, and has the characteristics of highly efficient energy-saving, thinness, small volume and light weight.

Description

technical field [0001] The invention relates to a manufacturing method of a back-sealed vacuum insulation panel. Background technique [0002] Existing vacuum insulation panels include a core material and a gas-barrier film coated on the outside of the core material, and the inside is vacuumed. The packaging method of the gas-barrier film is generally to seal the edges on the three sides or the periphery of the plate-shaped core material. The edge banding of the vacuum insulation panel will form a thermal bridge during use, which will reduce the overall thermal insulation performance of the vacuum insulation panel spliced ​​together. Contents of the invention [0003] The purpose of the present invention is to provide a method for making back-sealed vacuum insulation panels, so as to solve the problem in the prior art that the edges of vacuum insulation panels that are edge-sealed around the edges will form thermal bridges during use, reducing the vacuum insulation panels ...
