Abstract
The utility model discloses a vacuum insulated panel with a core material subjected to edge cutting processing. The vacuum insulated panel comprises the core material, a composite separating membrane and heatsealing edges. Four edges of the core material are subjected to edge cutting processing according to a certain inclination angle. The cross section of the core material is of a trapezoidal structure. The heatsealing edges are located on the bottom edges of the trapezoidal core material. The vacuum insulated panel with the core material subjected to edge cutting processing basically eliminates wrinkles on the corners. When the vacuum insulated panel is used on a refrigerator, the adhesiveness between the vacuum insulated panel and the wall of the refrigerator is enhanced, and the heat-insulating performance of the refrigerator is further guaranteed. The vacuum insulated panel avoids air leakage of microstructures caused by the wrinkles, greatly improves stability, facilitates splicing between the vacuum insulated panels, and reduces heat bridge effects of penetrability between two common vacuum insulated panels.

Background technique
Along with the progress of science and technology and the reinforcement of social enviroment protection awareness of saving energy, people more and more pay attention to the making and the use of heat-insulation and heat-preservation 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 the advantage of numerous uniquenesses such as the A level is not fired, the thermal insulation property of excellence, light weight, environmental protection, is widely used in the device as the heat insulation household refrigerator of needs, cooler bin, HEATING BOX.Usually, vacuum heat-insulating plate is fixed in the interlayer of refrigerator, thermal insulation apparatus and is used for insulation.
The core of conventional vacuum thermal shield is shaped as the rectangular of rule, and core is put into the obstructing film bag, vacuumizes heat-sealing and forms, and the heat-sealing mouth generally is positioned at the neutral position of core thickness.Because external and internal pressure is poor, two surfaces are pressed into smooth plane up and down; Four sides also tightly are pressed on the side of core together with the heat-sealing limit.Because the existence on heat-sealing limit, the side of conventional vacuum thermal shield all is uneven.Because core compression, cause the surplus that has of side obstructing film in addition, be present on the corner of vacuum heat-insulating plate with the form of fold.These folds can cause the applying degree of vacuum heat-insulating plate and refrigerator to reduce greatly, and these folds are cracky positions simultaneously, cause the microstructure gas leak phenomenon of vacuum heat-insulating plate easily, have influenced the life-span and the heat-shielding performance of vacuum heat-insulating plate.
The model utility content
The purpose of this utility model is intended to overcome existing deficiency, and the vacuum heat-insulating plate that provides a kind of core cutting edge to handle comprises core, composite barrier film and heat-sealing limit, it is characterized in that the cutting edge processing is all carried out according to certain angle of inclination in four limits of described core; Required core cross section is a trapezium structure; Described heat-sealing limit is positioned at the base of trapezoidal core.
Described angle of inclination is 30 ° ~ 60 °.
Described core is that the thin glass wool core of single or multiple lift is formed.
Described core is centrifugal cotton, flame cotton, short chopping is cotton or above combination in any forms.
Described composite barrier film is followed successively by plastic-aluminum combined layer, plastics composite bed, pet layer from outside to inside.
The utility model provides a kind of core cutting edge to handle the preparation method of vacuum heat-insulating plate, and its feature comprises the step of following order:
(1), multi-layer thin glass wool core is neatly piled up according to desired thickness;
(2) cutting edge all being carried out according to certain angle of inclination in four limits of above-mentioned core handles;
(3) core after the cutting edge is packed in the composite barrier film, carry out the vacuum heat-sealing;
(4) obtain the vacuum heat-insulating plate that required core cutting edge is handled.
Effect: the utility model compared with prior art has the following advantages:
(1) the prepared vacuum heat-insulating plate of the utility model is compared with common vacuum heat-insulating plate, and the composite barrier film and the core of the upper surface of vacuum heat-insulating plate, lower surface, side fit tightly, and all are smooth; Because the heat-sealing limit is positioned at the base of trapezoidal core, has eliminated the fold phenomenon of corner substantially, when on refrigerator, using, strengthen the degree of adhesion with the refrigerator wall, further guaranteed the heat-shielding performance of refrigerator;
(2) vacuum heat-insulating plate of the utility model preparation, the heat-sealing limit is positioned at the base of trapezoidal core, and four sides all are smooth, have eliminated the fold phenomenon of corner substantially, avoid the microstructure gas leak phenomenon that causes because of fold, improved the stability of vacuum heat-insulating plate greatly;
(3) vacuum heat-insulating plate of the utility model preparation because side all is smooth, and has certain angle of inclination, be very beneficial for the splicing of adjacent two vacuum heat-insulating plates, as shown in Figure 2, reduced perfoliate heat bridge effect between common two vacuum heat-insulating plates, as shown in Figure 3.
