Abstract

The invention discloses a vacuum insulation panel and a method for manufacturing the panel. The vacuum insulation panel comprises core materials and high gas-resisting composite membranes, wherein the core materials at least comprise multiple layers of inorganic fibrous layers which are stacked up and down or connected up and down through a binder; at least two layers in the multiple layers of inorganic fibrous layers have different inorganic fiber density or ingredients. The vacuum insulation panel is excellent in thermal insulation property; in comparison with other thermal insulation materials, the vacuum insulation panel with the same thickness is better in thermal insulation property; thus, in practical application, the thermal insulation effect realized by other materials is also realized by adopting the vacuum insulation panel with the small thickness, and the cost is saved.

Description

technical field [0001] The invention belongs to the field of construction, in particular to a thermal insulation core material of a vacuum insulation panel, and belongs to the field of E04B. Background technique [0002] Existing vacuum heat insulation panels are mainly composed of outer high-barrier film and inner heat insulation core material. The heat insulation core material is generally made of a combination of conventional heat preservation materials, glass fibers and aerogels. The disadvantages are high material costs and energy High consumption, not environmentally friendly. Contents of the invention [0003] In view of the shortcomings of the current prior art, the purpose of the present invention is to provide a core material of a vacuum heat insulation board and a manufacturing method thereof, so as to solve the shortcomings of high material cost and high energy consumption of products in the existing market. [0004] In order to achieve the above object, the t...
