Embodiment Construction

[0031] A vacuum heat insulation panel comprises a core material and a high gas-barrier composite film. The core material is one or more layers, at least one layer of which is composed of centrifugal cotton.

[0032] Preferably, the core material can be divided into an upper zone, a middle zone and a lower zone, and the middle zone is centrifugal cotton.

[0033] Preferably, the core material is one layer with a thickness of 2 mm. The core material here is provided with only one layer, indicating that the core material is composed of centrifugal cotton.

[0034] Preferably, the average diameter of the centrifugal cotton is 2-4 μm.

[0035] Preferably, the upper zone and / or the lower zone are made of one or more of ultra-fine glass wool fiber boards, aluminum silicate fiber boards, centrifugal glass wool boards, rock wool boards, textile fiber boards, and waste paper pulp boards.

[0036] A method of manufacturing the aforementioned vacuum insulation panel, comprising the step...

Abstract

Provided are a vacuum heat insulation board and a manufacturing method thereof. The vacuum heat insulation board comprises a core material and a high-air-resistance composite film. The core material is a one-layer or multi-layer material, wherein at least one layer is composed of centrifugal cotton. The vacuum heat insulation board is good in heat insulation effect, smaller thickness can be achieved under the heat conduction coefficient of the same class, the cost is reduced, danger of dust to the environment is avoided, and the environment protection effect is better.

Description

technical field [0001] The invention belongs to the field of construction, in particular to a vacuum heat insulation board and a manufacturing method thereof, 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] Aiming at the shortcomings of the current prior art, the purpose of the present invention is to provide 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 technical solution ...
