Abstract

An envelope fabric of an insulation board and a preparation process for the same are disclosed, wherein the envelope fabric of an insulation board comprises a glass fibre cloth layer, a first aluminium foil layer, a PET (polyethylene terephthalate) layer, a first nylon layer, a second aluminium foil layer, a second nylon layer and a PE (polyethylene) layer which are orderly compounded from outside to inside. The insulation board and the preparation process for the same disclosed by the invention have the following advantages that: the outmost side of the insulation board uses glass fibre cloth for acting important flame-retardant performance as well as scratch-resistant and puncture-resistant performances; and the insulation board is greatly enhanced in alkali resistance and ageing-resistant performance due to the utilization of the glass fibre cloth on the outmost side. The envelope fabric of an insulation board disclosed by the invention uses double-layer aluminium foil and double-layer nylon, thereby enhancing the air impermeability of the envelope fabric of an insulation board and ensuring the duration time of the vacuum degree of vacuum thermal insulation board. Thus, the service life of the vacuum thermal insulation board is ensured.

Description
