Abstract

Provided is a thermal insulation board with a vacuum thermal isolation plate, comprising a porous foam body (2) and a flexible vacuum thermal isolation plate (1). The porous foam body (2) is a hard polyurethane foam body or phenolic resin foam body having a density of 20 - 80 kilograms / cubic metre, and the porous foam body (2) is directly combined into a whole with at least one major surface and all side faces of the vacuum thermal isolation plate (1) in a foaming process. In the porous foam body, the dimensions of various foam pores are less than 0.3 millimetre and the closed porosity rate is more than 60%. The porous foam body (2) at the outside of the major surface of the vacuum thermal isolation plate (1) has a thickness of 1 - 50 millimetres.

Description

technical field [0001] The invention relates to a thermal insulation material, in particular to a thermal insulation material with a vacuum heat insulation board. Background technique [0002] Vacuum insulation panel (Vacuum Insulation Panel referred to as VIP) is a new type of high-efficiency thermal insulation material developed in recent years. It is usually composed of a bag made of gas barrier film, a core material made of heat insulating material and a getter, the getter and filling core material are put into a bag made of gas barrier film, and then the gas barrier film is made Vacuum the bag and seal it. The gas barrier film can keep the bag in a vacuum state, effectively avoid heat transfer caused by air convection, and insulate it from the outside world. However, since the VIP itself is a flexible rectangular plate, except for the relatively large areas of the two opposite main surfaces in the thickness direction, the areas of the four peripheral sides are very sm...
