Abstract

The utility model belongs to composite materials, which is a gypsum composite vacuum heat insulation board, which is composed of a gypsum decorative layer, a core material, a layered getter, and an aluminum-plastic composite bag. It adopts ultra-fine glass fiber cotton board produced by wet method as the core material, puts in layered getter, after drying, puts it into an aluminum-plastic composite bag for vacuum packaging to form a vacuum heat insulation board, and then heats it in a vacuum. It is obtained by wrapping a layer of gypsum decorative layer on the outside of the board as a whole. The gypsum decorative layer completely solves the problem that vacuum insulation panels cannot be directly used for building insulation, and provides a thermal insulation decorative material with a thermal conductivity of less than 0.010w/(m K) and a thickness of only about 15mm, which can be used for Wall partition insulation, building decoration insulation for roofs and ceilings, etc.

Description

Gypsum Composite Vacuum Insulation Panel

Technical field:

The invention relates to a composition of a gypsum composite vacuum heat insulation board, which belongs to the field of thermal insulation and decoration materials for buildings.

Background technique:

Building energy conservation is the implementation of sustainable development strategy, which has important practical significance for the country's energy conservation and emission reduction. One of the main measures for building energy saving is to widely use insulation products with low thermal conductivity and meet relevant requirements. At present, the main materials of wall insulation products and exterior wall decoration insulation boards mainly include extruded polystyrene board (XPS board), molded polystyrene board (EPS board), polyurethane foam board (PUF board), rock wool board, Glass wool, rubber powder polystyrene particle slurry, perlite slurry and foamed cement slurry, etc. The thermal conductivity of these insulation materials is 0.03-0.09w/(m·K), and the thickness is 60-300mm, and they cannot fully meet the requirements of building insulation materials. The thermal conductivity of the vacuum insulation panel produced by combining the core material made of glass wool or open-cell foamed polyurethane, the reactive adsorbent and the aluminum-plastic composite bag is only 0.003-0.005w/(m·K), and the thermal insulation performance is very good. Superior, currently widely used in refrigerator insulation. Due to the limitations of the material itself, the surface of the aluminum-plastic composite bag is smooth and hydrophobic, and it is not easy to bond with other materials, nor can it be reprocessed on its surface. Its installation and use conditions are relatively harsh, and it cannot be directly applied to the construction industry at present.

Invention content:

In view of this, the purpose of this utility model is to provide a gypsum composite vacuum heat insulation board, which improves the shortcomings of the existing vacuum heat insulation board. It is composed of a gypsum decorative layer, a core material, a layered getter, Bag composition. From the outside to the inside, there are gypsum decorative layers, aluminum-plastic composite bags, core materials, and layered getters. With this layer of plaster, it can be conveniently used directly or reprocessed on its surface. The gypsum decorative layer also has the function of protecting the aluminum-plastic composite bag. When the thickness of the gypsum layer is appropriate, it can not only give full play to the advantages of the extremely low thermal conductivity of the vacuum insulation board, but also have the excellent physical, chemical and electrical properties of the gypsum board, making it easy to install and use, light in weight, flame retardant, and soundproof. , vibration reduction and other characteristics. This composite material is easy to install, safe and reliable to use, and its service life can be as long as 50 years. The gypsum decorative layer completely solves the problem that vacuum insulation panels cannot be directly used for building insulation, and provides a thermal insulation decorative material with a thermal conductivity of less than 0.010w/(m K) and a thickness of only about 15mm, which can be used in Wall partition insulation, building decoration insulation for roofs and ceilings, etc. Of course, the thicker the vacuum insulation board and the thinner the gypsum layer, the lower the thermal conductivity, and vice versa, the higher the thermal conductivity, so the thermal conductivity and thickness can be adjusted. This is just to show that this effect can be obtained and not only effect.

Detailed ways:

The purpose of this utility model is achieved through the following technical measures: use the ultra-fine glass fiber cotton board produced by wet process with a specified thickness as the core material, which can be stacked in one layer or in multiple layers, and then put in a layered getter, bake After drying, put it into a VIP special aluminum-plastic composite bag to vacuumize and seal to form a vacuum heat insulation board, and then wrap a certain thickness of gypsum decorative layer on the outside of the vacuum heat insulation board as a whole. The thermal conductivity of the composite material obtained in this way is less than 0.010w/(m·K), and the thickness is only about 15mm. It is a thermal insulation and decorative material, which can be used for wall insulation, roof and ceiling insulation. Of course, the thicker the vacuum insulation board and the thinner the gypsum layer, the lower the thermal conductivity, and vice versa, the higher the thermal conductivity, so the thermal conductivity and thickness can be adjusted. This is just to show that this effect can be obtained and not only effect.

Description of drawings:

The concrete structure of the present utility model is described further in conjunction with accompanying drawing. The accompanying drawing is a schematic diagram of the structure of the new vacuum insulation panel of the present invention: 1 is an aluminum-plastic composite bag, 2 is a layered getter, 3 is a core material, and 4 is a gypsum decorative layer.

Select the ultra-fine glass fiber cotton board produced by the wet method with a specified thickness as the core material 3, then put in the layered getter 2, dry it, put it into the VIP special aluminum-plastic composite bag 1 and vacuumize and seal it to obtain vacuum heat insulation The composite material can be obtained by wrapping a layer of gypsum decorative layer 4 with a certain thickness on the outside of the vacuum insulation board.
