Problems solved by technology

This single-layer core board, single-layer high-barrier gas-barrier membrane bag structure vacuum insulation panel, once the surface is damaged, will cause problems such as air leakage, swelling, etc., thus losing the effect of heat insulation and fire prevention. Low impact strength, poor toughness, low surface puncture resistance, and the surface of the high-barrier air-barrier diaphragm bag is not smooth enough after vacuuming

Embodiment 1

[0033] A processing technology for a vacuum insulation panel with installation holes and not afraid of surface damage, the processing technology includes the following process steps:

[0034] The first step is to manufacture the inner core board 1 by a dry method, and use glass fiber filaments, fumed silica, nano-microporous materials, aerogels, fumed silica, nano-microporous materials, and airgel The carding machine is combed into flakes and laid on the conveyor belt. The conveyor belt transfers the flakes to the cutting machine. The cutting machine cuts the flakes into the set specifications, and the cut flakes are put into the mold cavity layer by layer. There are multiple layers inside, and a filling layer is laid between the layers. The inner core board 1 forms the installation groove of the getter material and the installation groove of the inner partition 1 through the mold, or processes the getter material on the inner core board 1 for installation. Groove and inner pa...

Embodiment 2

[0043] On the basis of Example 1, the difference between this Example 5 and Example 4 lies in that: the wrapped outer core board 4, the medium-alkali or alkali-free glass fiber with a diameter of 4um is chopped, and the fiber diameter is 8μm Mineral wool, fumed silica, aerogel, solid viscose and mica powder, according to the content of medium-alkali glass fiber chopped strands is 25 parts by weight, the content of mineral wool is 50 parts by weight, and the content of fumed silica is 5 parts by weight, the content of airgel is 5 parts by weight, the content of solid viscose is 3 parts by weight, and the content of mica powder is 8 parts by weight. Make a slurry with water, and transport the evenly stirred slurry to the forming net. Flat, then remove moisture by rolling and drying, and then press into a flat core board by high-temperature hot molding, and then make a slurry with water from moisture-proof agent, perlite powder, and radiation barrier agent. The content of moisture...

Embodiment 3

[0047] On the basis of Example 1, the difference between this Example 4 and Example 4 lies in that: the wrapped outer core board 4, the medium-alkali or alkali-free glass fiber with a diameter of 9um is chopped, and the fiber diameter is 12μm Mineral wool, fumed silica, aerogel, solid viscose and mica powder, according to the content of medium-alkali glass fiber chopped strands is 25 parts by weight, the content of mineral wool is 50 parts by weight, and the content of fumed silica is 5 parts by weight, the content of airgel is 5 parts by weight, the content of solid viscose is 3 parts by weight, and the content of mica powder is 10 parts by weight. Make a slurry with water, and transport the evenly stirred slurry to the forming net. Flat, then remove moisture by rolling and drying, and then press into a flat core board by high-temperature hot molding, and then make a slurry from moisture-proof agent, perlite powder, and radiation barrier agent with water. The content of moistu...

Abstract

The invention relates to a processing technology of a vacuum heat insulation panel with installation holes and without fear of surface damage. The vacuum heat insulation panel includes an inner vacuum structure layer and at least one outer vacuum structure layer wrapped around it. The inner vacuum structure layer consists of an inner core board It is composed of a high-vacuum barrier film wrapped on the outside. The inner core board is made of glass fiber and other materials by combing hot-pressing or dispersing wet and vacuum processes. The inner vacuum structure layer is made of high-vacuum heat-sealing equipment; the outer vacuum The structural layer is composed of an outer core board and a high-vacuum barrier film wrapped outside it. The outer core board is made of glass fiber and other materials by mixing and dispersing wet method and vacuum forming process. The air-absorbing material can be embedded on the outer core board and then loaded into the outer core board. Inside the high-vacuum barrier film, the outer vacuum structure layer is made with high-vacuum heat-sealing equipment. The installation hole is separated from the core layer by a partition plate provided with a through hole. After the surface of the vacuum heat insulation board is damaged, it does not bulge, does not expand, does not absorb water, and can retain heat preservation and heat insulation performance.

Description

technical field [0001] The invention relates to the technical field of thermal insulation, heat insulation and fireproof boards, in particular to a processing technology of vacuum heat insulation boards with installation holes and without fear of surface damage. Background technique [0002] With the emphasis on energy saving and emission reduction in various countries, thermal insulation technology has developed rapidly. Among them, vacuum insulation panels, as a new type of thermal insulation material and device, have received more and more attention. Vacuum insulation panels are composed of insulation core materials, high-barrier membranes and adsorbents, among which the high-barrier membranes can effectively reduce gas infiltration into the insulation system, maintain internal vacuum, and maintain product performance. At present, most of the single-layer core board and single-layer barrier membrane structures are used in the market. This structure can prevent gas infiltr...
