Abstract
The invention discloses a vacuum insulated panel for core material edge-cutting processing, and a preparation method for the vacuum insulated panel. The vacuum insulated panel comprises a core material, a composite barring film and a heat sealing edge, wherein the four edges of the core material are subjected to edge cutting according to a certain inclination angle; the cross section of the core material adopts a trapezoid structure; the heat sealing edge is positioned at the bottom edge of the core material. According to the vacuum insulated panel prepared by the invention, the folding of corners can be basically eliminated; when the vacuum insulated panel is used on a refrigerator, the degree of fit between the refrigerator wall and the vacuum insulated panel can be improved, and the heat insulation performance of the refrigerator can be further ensured; the microstructure air leakage phenomenon caused by the folds can be avoided, and the stability of the vacuum insulated panel is greatly improved; the splicing of the vacuum insulated panels is facilitated, and the through heat bridge effect generated between two common vacuum insulated panels can be reduced.
Description
Technical field
The present invention relates to a kind of vacuum heat-insulating plate and preparation method thereof, specifically relate to vacuum heat-insulating plate of a kind of core cutting edge processing and preparation method thereof.
Background technique
Along with the reinforcement of scientific and technological progress and social enviroment protection awareness of saving energy, people more and more pay attention to making and the use of heat-insulating heat-preserving material, and the thermal insulation property of especially emerging to some, environmental protection sandwich material, the research of sound insulation value are more and more deep.
Vacuum heat-insulating plate has advantages of numerous uniquenesses such as A level is not fired, excellent thermal insulation property, light weight, environmental protection, is widely used in the device household refrigerator as heat insulation in needs, cooler bin, HEATING BOX.Conventionally, vacuum heat-insulating plate is fixed in the interlayer of refrigerator, thermal insulation apparatus for insulation.
The core of conventional vacuum thermal shield is shaped as regular rectangular, and core is put into obstructing film bag, vacuumizes heat-sealing and forms, and hot-seal is generally positioned at the neutral position of core thickness.Because external and internal pressure is poor, upper and lower two surfaces are pressed into smooth plane; Four sides are also tightly pressed on the side of core together with hot edge seal.Due to the existence of hot edge seal, the side of conventional vacuum thermal shield is all uneven.Due to core compression, cause the surplus that has of side obstructing film in addition, be present in the form of fold on the corner of vacuum heat-insulating plate.These folds can cause the laminating degree of vacuum heat-insulating plate and refrigerator greatly to reduce, and these folds are cracky positions simultaneously, easily cause the microstructure gas leak phenomenon of vacuum heat-insulating plate, have affected life-span and the heat-shielding performance of vacuum heat-insulating plate.
Summary of the invention
Object of the present invention is intended to overcome existing deficiency, and a kind of vacuum heat-insulating plate of core cutting edge processing is provided, and comprises core, composite barrier film and hot edge seal, it is characterized in that cutting edge processing is all carried out according to certain angle of inclination in four limits of described core; Required core cross section is trapezium structure; Described hot edge seal is positioned at the base of trapezoidal core.
Described angle of inclination is 30 ° ~ 60 °.
Described core is the thin glass wool core material composition of single or multiple lift.
Described core is that centrifugal cotton, flame cotton, short chopping cotton or above combination in any form.
Described composite barrier film is followed successively by plastic-aluminum combined layer, plastics composite bed, pet layer from outside to inside.
For the technological scheme that realizes object employing of the present invention is: provide a kind of core cutting edge to process the preparation method of vacuum heat-insulating plate, its feature comprises the step of following order:
(1), according to desired thickness, multi-layer thin glass wool core material is carried out neatly stacking;
