Abstract

The invention provides a vacuum thermal insulation board, which can solve the problem of poor thermal insulation effect in the prior art. According to the technical scheme, the vacuum thermal insulation board comprises an outer coating material and a core material; a getter is arranged in the core material; the outer coating material is formed by combining through a single-faced or double-faced coating material without an aluminum foil; the core material is a glass fiber assembly in a uniform lamination structure; and glass fiber is 1-3 microns in diameter. The invention further provides a preparation method of the vacuum thermal insulation board. As the internal vacuum degree of the vacuum thermal insulation board is very high, and heat is blocked by the glass fibers in the core material layer by layer in a transfer process, the speed of heat transfer is greatly reduced, and good thermal insulation effect can be achieved. Meanwhile, an edge thermal bridge effect is eliminated as no aluminum foil is arranged on the coating material, so that the vacuum thermal insulation board has a good thermal insulation effect.

Description

technical field [0001] The invention belongs to the technical field of heat insulation profiles, and in particular relates to a vacuum heat insulation panel which can be used in heat preservation and heat insulation products and a preparation method thereof. Background technique [0002] During the heat transfer process, the thermal conductivity of the insulation material is relatively high, resulting in serious heat loss in the refrigerator. At present, there are two main problems in the vacuum insulation panels used in batches by various refrigerator companies to ensure the heat preservation effect of products: 1. Outer packaging materials: At present, composite materials containing aluminum foil layers are generally used for outer packaging materials, which will inevitably generate heat along the The heat bridge effect of the outer packaging material directly transferred to the other side, resulting in poor insulation effect of the vacuum insulation panel (such as figure...
