Description

Thermal insulation board with vacuum insulation board

Technical field

The invention relates to an insulation material, in particular to an insulation material with a vacuum insulation board.

Background technique

Vacuum Insulation Panel (VIP) is a new type of efficient insulation material developed in recent years. It is usually composed of a bag made of a gas barrier film, a core material composed of a heat insulating material, and a getter. The getter and the filled core material are placed in a bag made of a gas barrier film, and then the gas barrier film is made. The bag is evacuated and sealed. The gas barrier film can keep the inside of the bag in a vacuum state, and effectively avoid heat transfer caused by air convection, and is insulated from the outside. However, since the VIP itself is a flexible rectangular plate, except for the relatively large area of the two opposite main surfaces in the thickness direction, the area of the four sides of the periphery is small, and when picked up, it is easy to make two The main surface is curved and deformed; the thickness of the gas barrier film is thin, and the two main surfaces are relatively easy to leak. In addition, the bag made of gas barrier film is easy to be pierced or broken during production or use. Gases such as nitrogen, oxygen, carbon dioxide, hydrogen and water vapor penetrate into the VIP through the defect position of the gas barrier film, affecting VIP. The service life.

In response to these two problems, a heat insulating panel composite material is proposed in Chinese Patent No. CN102482446, in which an extruded thermoplastic polymer foam having a cavity is defined, and the vacuum heat insulating panel is completely placed in the cavity thereof. . The VIP within the cavity is protected by extrusion of a thermoplastic polymer foam to provide optimum gas barrier properties and strength. However, the extruded thermoplastic polymer foam has a high thermal conductivity and cannot meet the practical needs.

Summary of the invention

The invention aims to provide an insulation board with a vacuum insulation panel, which not only enhances the external mechanical strength of the VIP, but also improves the service life of the VIP.

The technical proposal of the present invention is: an insulation board with a vacuum insulation panel, comprising a porous foam body and a vacuum insulation board; the porous foam body is a rigid polyurethane foam having a density of 20-80 kg/m 3 or a phenolic resin foam, and the porous foam body is integrated with at least one main surface and at least one side surface of the vacuum insulation panel; the porous foam has a closed cell ratio of more than 60%; and the porous foam body is in the vacuum insulation panel main The portion outside the surface has a thickness of 1 to 50 mm.

Polyurethane (Polyurethane in English, abbreviated as PU, collectively referred to as polyurethane) is a general term for macromolecular compounds containing repeating carbamate groups in the main chain. Rigid polyurethane is a rigid material. The rigid polyurethane foam has the dual functions of heat preservation and waterproofing. Its thermal conductivity is low, only 17~24mW/m·k, which is equivalent to half of extruded thermoplastic polymer foam. The thermal conductivity of the insulation material is the lowest.

Phenolic resin (English name: Phenol Formaldehyde, PF for short), phenolic resin foam also has the dual functions of heat preservation and waterproofing. Its thermal conductivity is about 23-28mW/m·k, which is slightly higher than that of rigid polyurethane foam, but it is used in the environment. When the temperature is high, the temperature resistance is higher than that of the rigid polyurethane foam, which is not easy to shrink and deform, and has a longer service life.

Fig. 1 is a graph showing the relationship between density and thermal conductivity of a rigid polyurethane foam obtained by the inventors. As shown in Fig. 1, the rigid polyurethane foam has a thermal conductivity of 20-80 kg/m3 and its stability, and the rigid polyurethane foam has a closed cell ratio of more than 90%. The thermal conductivity of rigid polyurethane foam is closely related to the closed cell ratio, pore size and gas composition in the pores. In the current production process, when the foaming conditions are the same, the rigid polyurethane foam having a density of less than 20 kg/m 3 has a low closed cell ratio, a thin bubble wall, and easy gas permeation, so that the overall thermal conductivity of the material is high. Fig. 2 is a graph showing the relationship between the density and thermal conductivity of the phenolic resin foam obtained by the inventors. As can be seen from Fig. 2, when the phenolic resin foam density is less than 30 kg/m 3 , the phenolic resin foam has a high thermal conductivity and a discrete distribution. The density is generally selected from 30 to 60 kg/m3, and the thermal conductivity is low and stable under these conditions. The high density of the phenolic resin foam is not particularly obvious for the thermal conductivity, but the raw material consumption is relatively high, so the optimum foaming density of the phenolic resin foam is 30-60 kg/m 3 .

Therefore, when the above porous foam has a density of 20 to 80 kg/m 3 , the thermal conductivity is low and the material consumption is small. In the case of the same foaming conditions, the density of the above porous foam is too low, indicating that the dimensions of the internal cells are large, the overall strength and toughness are insufficient, and the internal cells are easily broken and penetrated, resulting in convection of the internal gas. The thermal conductivity increases rapidly; the density of the porous foam is too high, and although the dimensions of the internal cells are reduced, the consumption of raw materials is large, and the increase of the closed cell ratio is not effective, so that the thermal conductivity is not reduced. Moreover, if the density of the porous foam is too large, the porosity of the porous foam is lowered, thereby increasing the solid thermal conductivity of the porous foam itself, so that the overall thermal conductivity of the thermal insulation panel is improved.

According to research by the inventors, since the thermal conductivity of the porous foam is higher than that of the vacuum insulation panel, which is about 10 times that of the vacuum insulation panel, the thickness of the porous foam above the main surface of the vacuum insulation panel is larger, and the heat insulation after coating is The composite thermal conductivity of the board will be higher. When the thickness of the above porous foam outside the main surface of the vacuum insulation panel is less than 1 mm, the fluidity of the foam raw material is poor, resulting in uneven foaming and poor mechanical strength. When the thickness of the above porous foam is more than 50 mm, not only more raw materials are consumed, but also the cost is high, and the composite thermal conductivity is also increased.

3 shows that the rigid polyurethane foam obtained by the inventors of the present invention has a rigid polyurethane foam having a density of 53 kg/m 3 selected on the vacuum insulation panel and the outer surface of the lower main surface, and the vacuum insulation panel is completely coated. The inner filling of the vacuum insulation board is glass fiber, and the barrier bag is a common barrier bag of the same batch of VIP. To accelerate the aging of the vacuum insulation board, no vacuum material is added in the vacuum insulation board. The thickness of the vacuum insulation board is 11 mm, and the thickness of the rigid polyurethane foam is 2 mm, 4 mm, 7 mm, 11 mm, 25 mm and 50 mm, the aging temperature is 70 ° C, and the aging time is 90 days. The composite thermal conductivity of the thermal insulation board characterizes the aging resistance of the vacuum insulation panel, and the relationship between the above thickness of the rigid polyurethane foam and the overall thermal conductivity of the thermal insulation panel. As shown in FIG. 3, the greater the thickness of the rigid polyurethane foam, the higher the thermal conductivity of the thermal insulation panel; the lower the thickness of the rigid polyurethane foam, the aging of the vacuum insulation panel is too fast; the rigid polyurethane foam The above thickness selection is 5-25 mm as the best solution.

Figure 4 shows the composite thermal conductivity of a vacuum insulation panel coated with a phenolic resin foam by the inventors of the present invention to characterize the aging resistance of the vacuum insulation panel. Among them, the thickness of the phenolic resin foam on the vacuum insulation panel and the outer surface of the lower main surface is 10 mm, the thickness of the vacuum insulation panel is 11 mm, the aging temperature is 145 ° C, and the aging time is 90 days. As shown in FIG. 4, it can be seen from the thermal conductivity variation profile that the greater the thickness of the phenolic resin foam, the higher the thermal conductivity of the thermal insulation panel; the thickness of the foam is too low, and the vacuum insulation panel ages too fast. The above thickness of the phenolic resin foam is selected to be 5-25 mm as the optimum solution.

The phenolic resin foam-coated vacuum insulation panel has a longer temperature resistance and a longer service life. Due to the poor high temperature resistance of rigid polyurethane foams, rigid polyurethane foam coated vacuum insulation panels are mainly used in normal temperature or low temperature environments.

The present invention uses a rigid polyurethane foam or phenolic foam having a density of 20-80 kg/m 3 and a closed cell ratio of more than 60% and a thickness of 1 to 50 mm outside the main surface of the vacuum insulation panel to provide a flexible vacuum. The insulation board is directly coated, which can strengthen the external mechanical strength of the flexible vacuum insulation board and become just Insulation board with vacuum insulation board; porous foam is not easy to aging and delamination, thus extending the service life of vacuum insulation board.

In a preferred embodiment, the portion of the porous foam outside the main surface of the vacuum insulation panel has a thickness of 5 to 25 mm. From the three aspects of cost, protection strength and thermal conductivity, this thickness of porous foam is the best choice.

Further, the outer surface of the portion of the porous foam outside the main surface of the vacuum insulation panel is covered with a decorative material layer.

The decorative material layer has the function of beautifying the appearance and protecting the above porous foam, so that the thermal insulation board is quick to install, more convenient to use and transport, and can be used in various occasions to meet the needs of different customers.

In particular, the decorative material layer is any one of a calcium silicate board, a glass magnesium board, an aluminum board, a galvanized steel sheet, a plastic board, a gypsum board, a cement fiber board, and a wooden decorative panel.

The above-mentioned plates are easy to obtain, low in price, and environmentally friendly, and are suitable for promotion and application.

The decorative layer has at least two folded edges which are respectively integrated with corresponding side faces of the porous foam. In practical applications, fasteners can be placed on the hem to facilitate the fixation of the two parts of the product.

A functional member is mounted inside or at least one side or one major surface of the porous foam. The functional component is one or more functional materials in the reinforcing sleeve, the fixing strip, the fixing buckle, the decorative fastener, the pipeline reserve, and the photovoltaic material, so as to adapt to the needs of different occasions.

The thermal insulation board with vacuum insulation board of the invention has the following positive effects compared with the prior art:

(1) The use of a rigid polyurethane foam or a phenolic resin foam having a low thermal conductivity improves the heat insulating property and has a good waterproof function. Furthermore, the above porous foam is a hard material, and the mechanical strength and high temperature resistance are much larger than that of the extruded thermoplastic polymer foam, and it is not easy to shrink and deform, and the external mechanical strength of the vacuum insulation panel can be better strengthened, thereby being better. Prolongs the service life of the vacuum insulation panel. In particular, it replaces the use of traditional vacuum insulation panels in the fields of refrigerators, vending machines, refrigerators and building insulation. The utility model solves the problems that the traditional vacuum insulation board is in the process of installation and use, because the sealed bag is a film product, and the barrier property is affected due to insufficient strength and being easily pierced and damaged.

(2) In the production process, the above porous foam can be directly combined with the vacuum insulation panel by using a mold or a laminating machine line directly under an atmospheric environment or a room temperature, and the production efficiency can be greatly improved. At the same time, since the above porous foam is directly combined with the vacuum insulation panel, the connection relationship is closer, not only The insulation is better and the porous foam is less prone to aging and delamination, thus extending the life of the entire product.
