Abstract

The invention provides a vacuum insulated panel core material, a preparation method thereof and a vacuum insulated panel. The vacuum insulated panel comprises a core material and a gas barrier bag; and the core material is packed in the gas barrier bag in vacuum to prepare the vacuum insulated panel. The core material consists of three raw materials of nanometer gas-phase silicon dioxide with a mass fraction of 60-95%, reinforced viscous fibers with a mass fraction of 3-35% and radiation light screening agents with a mass fraction of 2-10%. The preparation method of the core material prepares the core material through the steps of uniform mixing of the raw materials, molding through pressing, cutting and wrapping of breathable non-woven cloth materials without transmitting powder; and the core material is dried to load in the gas barrier bag for vacuumizing and sealing to prepare the vacuum insulated panel. The core material is low in solid heat conducting coefficient, low in shrinkage rate, low in density and high in strength; and the corresponding vacuum insulated panel is low in heat conducting coefficient, high in strength and long in service life.

Description

technical field

[0001] The invention relates to the technical field of thermal insulation materials, in particular to a core material of a vacuum thermal insulation panel, a preparation method thereof, and a vacuum thermal insulation panel. Background technique

[0002] With the continuous development of the global industrialization process and the massive consumption of fossil energy, on the one hand, we are facing an energy crisis, and on the other hand, the problem of environmental pollution is becoming more and more serious. Vacuum insulation panel (Vacuum Insulation Panel, referred to as VIP) as a new type of super insulation material, its thermal conductivity is low, only 1 / 5-1 / 10 of the thermal conductivity of traditional insulation materials, excellent comprehensive performance, wide source of raw materials, moderate price, It has been popularized and applied in fields that require high heat insulation, such as refrigerators, cold chain logistics, cold storage, etc.,...
