Abstract

The present invention relates to a vacuum insulation panel (1) comprising a core material (2) with open porous structure and a barrier (3) that holds the core material (2) together. The open porous core material (2) is filled into a barrier (3) preferably together with a getter material, depending on the material properties forming the core material (2) and vacuumed. Thus, a vacuum insulation panel (1) is realized comprising the open porous core material (2) having low thermal conductivity coefficient, with increased insulation effectiveness.

Description

VACUUM INSULATION PANEL WITH INCREASED INSULATION
EFFECTIVENESS
The present invention relates to a vacuum insulation panel.
Nowadays vacuum insulation panels are used in various fields since they have better performance with respect to the conventional insulation materials and since they provide better thermal resistance by using the insulating feature of the vacuum. Basically, a vacuum insulation panel is produced by putting a porous core material into a membrane (outer protective envelope) exclusively or together with getter material that retains gas and moisture according to the characteristic of the core material, vacuuming and closing it by providing leak-proofing. In the vacuum insulation panels, in order to obtain the vacuum effect, the gas pressure is enabled to be decreased by reducing the number of gas molecules in the environment. In the state of the art, materials such as precipitated silica, fumed silica, aerogel, fiberglass, open-cell extruded polystyrene and open-cell polyurethane, etc. are used as the core material.
In the state of the art United States Patent Document no. US4681788, the mixtures of precipitated silica and fly ash in different ratios are used as the core material of the vacuum insulation panel.
The aim of the present invention is the realization of a vacuum insulation panel, the cost of which is decreased without changing the insulation effectiveness.
The vacuum insulation panel realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof is produced by vacuuming and pressing an open-porous core material placed into a barrier to prevent scattering. The core material of the present invention comprises waste polyurethane that is pulverized so that the particle size thereof is between 1 nanometer and 20 nanometers. By means of the waste polyurethane whereof the particle size is reduced by pulverization, the insulation efficiency of the insulation material is increased. By means of the present invention, the production cost of the vacuum insulation panel is decreased without changing the insulation performance thereof and eco- friendly products are obtained by recycling waste polyurethane.
A vacuum insulation panel realized in order to attain the aim of the present invention is illustrated in the attached figures, where:
Figure 1 - is the schematic view of a vacuum insulation panel of the present invention.
The elements illustrated in the figures are numbered as follows:
1. Vacuum insulation panel
2. Core material
3. Barrier
The vacuum insulation panel (1) comprises a core material (2) with open porous structure and a barrier (3) that holds the core material (2) together. The open porous core material (2) is filled into a barrier (3) preferably together with a getter material, depending on the material properties forming the core material (2) and vacuumed. Thus, a vacuum insulation panel (1) is realized comprising the open porous core material (2) having low thermal conductivity coefficient, with increased insulation effectiveness.
The core material (2) of the present invention comprises waste polyurethane that is pulverized so that the particle size thereof is between 1 nanometer and 20 nanometers. The porous waste polyurethane reaches very low thermal conductivity coefficient values (4.0 mW/m.K-4.5 mW/m.K) when vacuumed by decreasing the particle size. The thermal conductivity value of the vacuum insulation panel (1) can be adjusted by changing the particle size distribution and the porous structure of the waste polyurethane. As the particle size gets smaller, the thermal conductivity coefficient of the waste polyurethane decreases and conductivity of the vacuum insulation panel (1) decreases. In an embodiment of the present invention, the core material (2) comprises waste polyurethane with a density between 30 kg/m 3 and 50 kg/m 3. The density of the vacuum insulation panel (1) can be adjusted by changing the particle size of the waste polyurethane during the pulverization process. As the density of the waste polyurethane, hence of the core material (2) decreases, the thermal conductivity value of the vacuum insulation panel (1) decreases and the insulation performance is improved.
In an embodiment of the present invention, the core material (2) comprises 10% glass fiber by weight and waste polyurethane the particle size of which is between 1 nanometer and 20 nanometers. Glass fiber prevents agglomeration of waste polyurethane with decreased particle size and provides easy homogeneous dispersion in the core material (2). Thus, the flexibility of the vacuum insulation panel (1) is increased.
In an embodiment of the present invention, the vacuum insulation panel (1) is suitable to be used inside the door and/or the body of a household appliance.
In a derivative of this embodiment, the household appliance is a cooling device.
In a derivative of this embodiment, the household appliance is an oven.
In a derivative of this embodiment, the household appliance is a laundry dryer
In a derivative of this embodiment, the household appliance is a dishwasher. By means of the present invention, particularly by means of the polyurethane with decreased particle size, the thermal conductivity of the vacuum insulation panel (1) is reduced, enabling the cooling device (1) to operate more efficiently. Moreover, the amount of waste polyurethane, that is produced while destroying the used cooling devices (1) and that is destroyed by being burned or buried into the ground, is decreased. By means of the recycling of the waste polyurethane used in the production of the vacuum insulation panel (1), the energy and material consumption is reduced and environmentally-friendly products are produced.
