In space industry.
Japan Patent JP3712129A discloses a kind of vacuum heat insulation materials by spraying 0-7.0% matter in glass wool
The water of amount mark, is pressed at 250 DEG C-450 DEG C.
Japan Patent JP11-506708A discloses and a kind of uses the inorganic viscous of low melt glass component and boric acid etc.
Knot agent, coordinates the dissolved element of fiber to obtain vacuum heat insulation materials on the intersection point of the inorfil of internal core.
Disclosing a kind of vacuum heat insulation materials in Japan Patent JP3580315A, arranging compressing temperature is that core is firm
Just start the temperature of deformation, carried out below pyroplastic deformation temperature.
Domestic patent, mainly by binding agent a small amount of for the inside core surface-coated of vacuum heat insulation materials, common have phenol
The inorganic binders such as the organic binder bonds such as urea formaldehyde, epoxy resin, acrylic resin, starch or waterglass, boric acid, colloidal silica
Deng.The use of binding agent improves the operability of glass fibre and the flatness of heat-barrier material, but binding agent causes glass
In glass fiber, the vacuum in follow-up work declines, it is impossible to maintain higher heat-proof quality.It addition, only by the nothing of internal core
Bonding between organic fiber, the core insufficient strength produced, frangible, it is difficult to be inserted in external film.
Although patent disclosed above is from different perspectives, uses different preparation methoies and technology, significantly widened vacuum exhausted
The range of hot material.But described vacuum heat insulation materials unresolved how producing possess that intensity is suitable, operability
Strong core.Therefore, these problems actually current techniques and the important topic of scientific research personnel how are solved.
Summary of the invention
The purpose of the present invention is intended to overcome the deficiencies in the prior art, it is provided that a kind of vacuum heat-insulating plate, have higher intensity,
The vacuum heat-insulating plate that heat insulation effect is excellent, the electrolyte solid particle particularly separated out is filled or is attached to glass fibre skeleton
On, the aperture of core can be significantly reduced, when vacuum heat-insulating plate internal gas pressure raises, gaseous exchange reduces, thus is effectively increased
In the service life of vacuum heat-insulating plate, meanwhile, improve the heat-insulating property of vacuum heat insulation materials to a certain extent, to dynamo-electric, stone
The energy-conservation of oil, chemical industry, building and aerospace field is made contributions.
A kind of vacuum heat-insulating plate of the present invention is the technical scheme is that, including core for realizing the purpose of the present invention
Material, described core includes the glass fibre after fibrosis processing, after glass fibre even application electrolyte solution, then carries out perseverance
Temperature heating and pressurized treatments, it is characterised in that electrolyte solution accounts for the 7.2 wt %-18.0wt % relative to glass fibre, permanent
Temperature heating-up temperature is core pyroplastic deformation temperature 0 DEG C more than-150 DEG C.
Further, described electrolyte solution carries out solvent evaporation during heated at constant temperature, and electrolyte solid particle separates out attachment
Or fill on the glass fibers, wherein electrolyte solution be sodium chloride, calcium chloride, potassium chloride, magnesium chloride, sodium nitrate, calcium nitrate,
Any one or any two kinds in magnesium nitrate, sodium sulfate, magnesium sulfate, potassium sulfate, electrolyte Solids Particle Diameter is not more than glass
The average diameter of glass fiber.
Further, wherein core pyroplastic deformation temperature is 500 DEG C, and choosing heating-up temperature is 500 DEG C-650 DEG C.
Further, said method the vacuum heat-insulating plate prepared, the core of described vacuum heat-insulating plate is by the electricity separated out
Solve the attachment of matter solid particle or be filled in the formed body in glass fibre skeleton.
Above-mentioned vacuum heat-insulating plate can be used for exterior-wall heat insulation for building, the insulation of space shuttle crust or cold preservation, freezing etc.
In various fields.
Application effect: the present invention compared with prior art, has the advantage that
On the one hand (1) do not use binding agent, glass fibre can be made closely sealed closely, non-restoring after compression and also in use, row
Except gas produces in binding agent, keep higher vacuum；On the other hand, although the interpolation of binding agent can be to a certain extent
Increase the intensity of core, but during operative, content of binder is wayward, easily causes blanket of glass wool surface not
Smooth, and then make follow-up work complex operation, meanwhile, the vacuum heat-insulating plate performance under thickness surface out-of-flatness is the most unstable.
(2) core have employed the electrolyte solution of proper ratio, it is thus achieved that stronger core intensity, and then outside core loading
During cladding gas barrier film, operability improves.
(3) improve the temperature of conventional thermostatic heating, be set to more than pyroplastic deformation temperature, core surfaces few fibers
There is fracture or efflorescence, improve the planarization after core compacting, it is simple to the coating of subsequent handling PUR.
(4) the electrolyte solid particle separated out is filled or is attached on glass fibre skeleton, can significantly reduce the hole of core
Footpath, when vacuum heat-insulating plate internal gas pressure raises, gaseous exchange reduces, thus is effectively increased the service life of vacuum heat-insulating plate.
