The side view of the bag manufactured in the mode shows an □ shape, the inner filling material can be maximally contacted with the periphery of the outer bag, and the side edge of the manufactured vacuum insulation panel has no redundant membrane material, so that the size deviation caused by folding edges of the conventional product and the gap problem in splicing are reduced.
Description
The technical field is as follows:
the invention relates to the field of heat insulation materials, in particular to a back edge-sealed vacuum heat insulation plate.
Background art:
compared with the traditional heat insulation materials such as polyurethane foam or glass fiber, VIP does not use Ozone depletion Substances (Ozone depletion sustances) in the production and application processes, the heat conductivity coefficient of VIP can reach 3-4 mW/m K, the heat resistance of VIP is 10 times or even higher than that of the common heat insulation materials, the thickness of VIP is only 1/7 of the common heat insulation materials, the VIP has the double advantages of environmental protection and energy saving, and therefore the VIP is widely applied to the fields of refrigerators, buildings and the like and is the most advanced high-efficiency heat insulation material in the world at present.
The traditional vacuum insulation panel generally adopts a three-edge sealing envelope type external coating material, and then redundant membrane bags (edge sealing) after vacuumizing and sealing are folded and fixed on the surface of a product by using adhesive tapes or glue. This type of product has a large dimensional deviation due to the folding, and a large amount of tape or glue is used, resulting in an increase in cost.
Application No. 201230298065.0, filed an appearance patent. The vacuum insulation panel for the building is manufactured by adopting a three-edge sealing mode, and has the function of reducing a certain heat bridge. However, the coating material manufactured in the mode can only be manufactured by one material, and if the composite film containing the metal base is selected, the thermal bridge effect is still large; in addition, the mode of no edge covering causes that a large amount of film materials are gathered at the head end and the tail end, which is not beneficial to the application and the expansion of products.
The invention content is as follows:
the invention designs a vacuum insulation panel with a novel structure aiming at the defects that the edge of a heat bridge of the traditional vacuum insulation panel is uneven after edge folding, and particularly the heat insulation effect is reduced due to overlarge gaps during splicing.
In order to achieve the purpose, the invention is realized by the following technical scheme:
the utility model provides a back banding formula vacuum insulation panel which characterized in that: the film bag adopts a back edge sealing structure, the edge sealing position of the film material is arranged on the film bag, and the side view of the film bag is in the shape of □.
The sealing position can also be arranged below the film bag or sealed at the upper and lower sides simultaneously.
The edge sealing is at least performed twice.
The film material between the two sealed edges can be selected from the same type or different types, so that the design of an optimization scheme in multiple aspects such as cost, performance, heat bridge effect and the like is achieved.
And the inner wall of the membrane bag is coated with heat insulation cold glue.
The heat insulation cold glue comprises 20-21% of ethylene oxide end capping polyether, 5-7% of polymer polyol, 5-8% of amino polyether, 5-7% of micromolecule dihydric alcohol, 0.5-2% of coloring agent and 0.5-3% of catalyst; 20-22% of polyethylene terephthalate, 8-10% of glycol modified polyethylene terephthalate, 3-5% of polybutylene terephthalate, 1-2% of thermoplastic elastomer, 3-5% of phosphate flame retardant and lubricant: 0.01 to 0.05 percent of the total weight of the paint, 3 to 5 percent of soluble metal salt and the balance of water.
The preparation method of the heat insulation cold glue comprises the following steps: drying the glycol modified polyethylene terephthalate for 6 hours at the temperature of 70-75 ℃;
mixing and granulating the dried glycol modified polyethylene terephthalate and other raw materials;
uniformly mixing the blended granules by a high-speed stirrer, and drying for 4 hours at the temperature of 145-150 ℃;
stopping drying, naturally cooling to 35-40 deg.C, placing soluble metal salt in high-speed stirrer, and stirring;
and continuously drying for 2 hours at the temperature of 70-75 ℃, and extruding and molding the dried mixture through an extruder.
The invention has the beneficial effects that:
the side view of the bag manufactured in the mode shows an □ shape, the inner filling material can be maximally contacted with the periphery of the outer bag, and the side edge of the manufactured vacuum insulation panel has no redundant membrane material, so that the size deviation caused by folding edges of the conventional product and the gap problem in splicing are reduced.
The cold glue has the advantages of high bonding strength, good dimensional stability, excellent heat resistance, high curing speed, suitability for automatic and rapid production, environmental friendliness and lower cost advantage, and is beneficial to improving the production efficiency and the product performance;
the cold glue shrinks sharply after being heated, the edge sealing is tightened, a better edge sealing effect is achieved, meanwhile, the film bag can be in maximum contact with the internal filling material after being heated and shrunk, the structure is more compact, and the heat preservation is better;
soluble metal salts are utilized to form a through pore structure in the extruded gum that facilitates providing shrinkage space during subsequent shrinkage.
