In space industry.
Japan Patent JP2005/019496A discloses the preparation method of a kind of glass wool formed body, have employed water spray
Mode carries out adding hot pressing again, and heating-up temperature is 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.
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 is led
In cause glass fibre, the vacuum in follow-up work declines, it is impossible to maintain higher heat-proof quality.It addition, only by internal core
Inorfil between bonding, the core insufficient strength produced, frangible, be 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

Being, heating-up temperature is set to 0 DEG C more than-150 DEG C of core pyroplastic deformation temperature, and applying pressure is no more than 1 air
Pressure, the time is 1 min-25min.
Further, described core is glass fibre, or glass fibre adds ceramic fibre, asbestos fibre, basalt
One or both combination in any in fiber.
Further, described core there occurs plastic deformation through heating pressurization rear surface few fibers, and along with fibre
Dimension fracture, the generation of pulverization situation.
Further, described core thermoplasticity temperature is 500 DEG C, and arranging core heating-up temperature is 500 DEG C-650 DEG C.
A kind of core of above-mentioned vacuum heat insulation materials, it is characterised in that described core sequentially pass through cut, be dried, reduce pressure envelope
The operation of dress, prepared vacuum heat insulation materials surface smoothness deviation is less than 2 millimeters.
Above-mentioned vacuum heat insulation materials is 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 in (1) core the connection between fiber not
Use binding agent, it is possible to make glass fibre closely sealed closely, non-restoring after compression and also in use, eliminate gas in binding agent
Produce, keep higher vacuum.
(2) when the present invention breaks that for a long time prepared by core, the conventional setting of heating-up temperature, is disposed at core thermoplastic
Property 0 DEG C more than-150 DEG C of deformation temperature so that the few fibers generation local fracture of core surfaces, efflorescence, core surfaces is put down
Whole property is improved, for, in the operation of follow-up coating hot-melt adhesive, reducing operation easier so that adds glue amount and is easier to control.
(3) when carrying out extrusion forming, it is provided with suitable force value and the time ensures that the planarization of core, thickness are same
Time, shorten the working time, improve production efficiency.
