Embodiment Construction

[0025] A vacuum insulation panel, comprising a core material and a high gas barrier composite film, the core material at least includes a multi-layer glass fiber layer 1, the multi-layer glass fiber layer is stacked up and down or connected up and down by an adhesive, the At least two of the multiple glass fiber layers have different glass fiber aspect ratios.

[0026] Please note that the multi-layer fiberglass layer here includes 2 layers and more than 2 layers.

[0027] The aspect ratio here refers to an average aspect ratio.

[0028] Preferably, the core material includes an upper layer area covering the glass fiber layer and / or a lower layer area located below the glass fiber layer.

[0029] Preferably, the upper zone and / or the lower zone are made of one or more of aluminum silicate fiber boards, centrifugal glass wool boards, rock wool boards, textile fiber boards, and waste paper pulp boards.

[0030] Preferably, the number of glass fiber layers is 4-100 layers, pref...

Abstract

The invention discloses a vacuum insulation panel and a manufacture method thereof. The vacuum insulation panel comprises a core material and a high-resistance gas compound film, wherein the core material at least comprises multiple glass fiber layers, the multiple glass fiber layers are stacked up and down or are connected up and down by virtue of a binding agent, and length-diameter ratios of glass fibers of at least two of the multiple glass fiber layers are different. The vacuum insulation panel disclosed by the invention has a relatively good insulation effect; under same heat conduction coefficients, a relatively small thickness can be achieved, the cost is lowered, the damage of dust to an environment is prevented, and the environmental-friendly effect is relatively good.

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...
