Problems solved by technology

[0004] However, since the core material used inside the vacuum insulation panels currently on the market is generally PU; once the vacuum protection surface layer on the surface of the vacuum insulation panels is destroyed, the flame retardancy of PU is poor; Thinner thickness, lower thermal conductivity, wider temperature range and longer service life

Abstract

The invention discloses a vacuum insulated panel produced from superfine glass wool with a wet process. The vacuum insulated panel comprises a core material, a gas adsorption material layer and an isolating film layer, wherein the core material is in the innermost layer and is a core panel produced from superfine glass wool, the gas adsorption material layer wraps the outer surface of the core material, and the isolating film layer wraps the outer part of the gas adsorption material layer. The invention further discloses a method for producing the vacuum insulated panel. The vacuum insulated panel has light weight, low conductivity, good elasticity, corrosion resistance, aging resistance, high stability, good heat insulation effect and ideal sound-absorbing effect and is non-toxic, non-combustible and pollution-free. The vacuum insulated pane has the thickness of 8-30 mum, the service life of over 15 years, the use temperature of -50-70 DEG C and the conductivity of 0.0018-0.0028W / m.K at 20 DEG C.

Description

technical field [0001] The invention relates to a thermal insulation board, specifically a superfine glass wool vacuum insulation board developed with ultrafine glass wool as the main raw material, which is light in weight, low in thermal conductivity, good in elasticity, non-toxic, and pollution-free. production method. Background technique [0002] Vacuum insulation panel (VIP panel) is a kind of vacuum insulation material. The vacuum insulation panel currently on the market is composed of a filling core material and a vacuum protection surface layer. It can effectively avoid heat transfer caused by air convection, so heat conduction The coefficient can be greatly reduced, the thermal conductivity is generally 0.0035w / m.k, and it does not contain any OD 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. [0003] VIP is mainly us...
