Glass fiber core material for vacuum heat insulation plate

Abstract

The invention discloses a glass fiber core material for a vacuum heat insulation plate. The glass fiber core material comprises a plate body and positioning structures, limiting clamping rails are arranged on the left side and the right side of the plate body, mortises are formed in the limiting clamping rails, clamping plates are arranged on the inner side of the plate body, aluminum-foil paper layers are arranged on the inner sides of the clamping plates, rubber pads are arranged on the inner sides of the aluminum-foil paper layers, vacuum film pipes are arranged on the inner sides of the rubber pads, and the positioning structures are arranged in the mortises. By arranging the clamping plates made of wood, the whole heat insulation plate can be borne, clamped and supported, meanwhile, the weight of the whole heat insulation plate can be reduced through the wood, the clamping plates can be pulled in the limiting clamping rails through limiting groove rails and limiting sliding blocks, and thus the clamping plates can be conveniently replaced; meanwhile, the rubber pads can be matched with a vacuum thin film tube through matching grooves, so that the stability of the position structure of the vacuum thin film tube can be guaranteed, and the problem of displacement of the vacuum thin film tube is avoided.

Description

technical field [0001] The invention relates to the technical field of vacuum heat insulation panels, in particular to a glass fiber core material for vacuum heat insulation panels. Background technique [0002] Vacuum insulation panel (VIP board) is the abbreviation of VacuumInsulationPanel in English. It is a kind of vacuum insulation material. It is composed of filling core material and vacuum protection surface. It can be greatly reduced, less than 0.035w / (㎡.k), and does not contain any ODS (ozonedepletingsubstances) materials. It has the characteristics of environmental protection and high efficiency and energy saving. It is currently the most advanced high-efficiency thermal insulation material in the world. Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantages are brittleness and poor we...

Problems solved by technology

[0004] The purpose of the present invention is to provide a glass fiber core material for vacuum heat insulation panels, which solves the problem that the material inside the existing general vacuum heat insulation panels is not easy to replace. The damage of the device reduces the service life of the device. At the same time, the core material is complex and expensive, and the position of the core material is not fixed, which may easily cause the problem of core material falling off.
