The present invention also provides a kind of vacuum heat-insulating plates 2, are made of the core material 1, barrier bag 5 and getter 6, the core
Material 1 is placed in barrier bag 5, and getter 6 is placed in inside core material 1, is vacuumized in barrier bag 5, and the core material 1 is folded by multilayer felt
Set, which is the fibrofelt containing biosoluble fibres, biosoluble fibres mutually passed around in the form of monofilament or
Overlap joint or intertexture are distributed and are formed interconnected gap, and adhesive is dispersed between monofilament and bonds closely, not individually with them
In the presence of.
Further, 85~100wt% of biosoluble fibres, cured 0~15wt% of adhesive；Biosoluble fibres
Avarage fiber diameter is≤30 μm, average fiber length is≤250mm.If the avarage fiber diameter of fruit fiber is greater than 30 μm, phase
The fiber number of plies is reduced in stack pile fiber mat product, and heat-transfer path shortens, and skeleton heat transfer increases, while interfibrous gap is obvious
Increase, probability increase is mutually collided between gas molecule, total heat-proof quality is deteriorated.If fibre length is greater than 250mm, felt mistake
Journey is dispersed into monofilament and has any problem, the decline of fiber utilization rate.
Shot content is preferably in 10wt% or less in biosoluble fibres.Slag ball refers to that partial size is greater than in fiber (cotton)
Granular, the blocky and club etc. for not being made into fiber of 0.25mm.Shot content should be low as far as possible, if shot content is 10%
More than, production process is difficult to completely remove using scummer, still suffers from a part and remains in fiber mat product, and afterwards
The barrier package bag for very likely piercing through or stabbing in the process of VIP outside core material is manufactured, the heat-proof quality of VIP is influenced.
Biosoluble fibres refer to the constant of dissolution rate K in simulation Human Lung liquiddis≥100ng/(cm2.hr)；It is raw
Object can dissolve fiber in inorfil (including mineral wool, rock wool, mineral wool, glass fibre, refractory fibre, ceramic fibre etc.) respectively at
Weight percent (the Na divided2O+K2O+CaO+MgO+BaO) > 18wt% and/or [(Na2O+K2O+CaO+MgO+BaO+B2O3)-
2*(Al2O3)] > 40wt%.
Biosoluble fibres can be made by centrifugal process or flame method or fiber elongation method or spin processes.Centrifugal process is usually will
Melting or dense molten feed liquid get rid of thread through centrifuge after discharge port outflow, then are vertically blown and are finally cooled to more carefully by high-speed flow
Fiber.Flame method is usually melting or dense molten feed liquid to be first cooled to crude fibre after discharge port outflow, then hung down by high-speed flame
Direct-injection, which is blown, is finally cooled to more fine fibre.Fiber made from centrifugal process and flame method is discontinuous fiber, and fiber shape is generally not
Rule, product are in flocculence mostly, therefore have the title of centrifugal cotton, flame cotton.Fiber elongation method is usually melting or dense molten feed liquid from out
It is acted on after material mouth outflow by the downward drawing gravitation drawing-off of certain speed and is finally cooled to thinner continuous fibrous, i.e., continuous fibre
Dimension.Spin processes generally refer to melting or dense molten feed liquid after discharge port outflow during being stretched or through air or through water or
Through coagulating bath or hot-air or hot inert gas cooling and solidifying at thinner continuous fiber.Continuous fiber in the fabrication process can be with
It is formed fibre bundle (or fiber stock, precursor) by multifilament and together, be conducive to steady production in this way and improve yield.It is single
Silk, as its name suggests, refers to the meaning of an independent fiber.Chopped strand is cut through cutting machine by certain length by continuous fiber
Disconnected to form, also someone is referred to as " chopped silk ".
Biosoluble fibres by above method manufacturing process it is also possible to a small amount of size is added, in favor of fiber
(precursor) manufactures and applies (including fibrofelt is made).Size can have an effect or combine with fiber surface, protect fiber not
Easily form fracture of wire or lousiness or filoselle.Size is mostly more expensive, and unfavorable to fiber dispersion containing adhesive component, so infiltration
The content that agent accounts for fiber is usually no more than 2.5wt%.
The biosoluble fibres are biological soluble organic fiber or biological soluble inorfil or biosoluble
Solve one of composite fibre or more than one combination.Biological soluble organic fiber such as biological soluble regenerated cellulose is fine
Dimension, biological soluble polyglycolide (PGA) fiber, biological soluble chitin and its derivant fiber etc..Biological soluble without
Machine fiber such as biological soluble rock wool, biological soluble mineral wool, biological soluble glass fibre, biological soluble fire resisting is fine
Dimension, biological soluble ceramic fibre etc..Biological soluble composite fibre such as biological soluble inorganic-polymer composite fibre, life
Object can dissolve inorganic overcoating polymer fiber etc..
The biological soluble of biosoluble fibres refers to that fiber can be very fast in the physiology lung liquid or body fluid of circulation
The behaviors such as dissolution, degradation occur for ground and the product of this behavior is absorbed and utilized or by organism repeats itself body by organism
System excludes the performance without generating harm to organism in vitro.Biosoluble fibres are provided with preferable biological soluble.
The biosoluble fibres, can be quick after entering in organism in addition to having preferable biological soluble performance
Dissolution, decompose finally be removed out it is external, preferably should also have crystallization it is few, easily at fine, brittleness is low and manufactures in fibrofelt
In journey not facile hydrolysis, it is molten disconnected the features such as.
The adhesive is one of liquid-type adhesive or powder-type adhesive or more than one combination.The present invention
Although felt in there may be certain adhesive, human health will not be constituted and be endangered.Cause are as follows: adhesive generally all with biology
It can dissolve fibres bond, not individualism；It is big absolutely and after the biosoluble fibres for being bonded with adhesive are sucked by human body
The content for being mostly due to binder on biosoluble fibres surface is few so that adhesion strength is poor between fiber, is easily hit by external force
It falls, and the exposed region that this biosoluble fibres can not cover adhesive because of fiber surface significant portion is constantly molten
It solves, fragment into thinner short fiber or fragment and finally cleared out of in vivo by human body.
Adhesive can be inorganic adhesive or organic adhesion agent.Liquid-type adhesive be desirable to water or solvent again into
Row interworking, has preferable mobility and concentration controllability, can have both the side such as uniformity, impregnability, operability and cyclicity
Face demand；Generally there is longer storage period at normal temperature, more stable, production practicability is good.Powder-type adhesive is preferably powder
Last particle is thinner, and granular size is best in 1mm or less, and such powder is just easy to be evenly dispersed in fibrofelt.
Total volatile organic compounds (TVOC) content of the adhesive is preferably 120g/L or less, benzene, toluene, second
Benzene, dimethylbenzene summation is 300mg/Kg hereinafter, free formaldehyde is 100mg/Kg or less.In this way, total volatile organic compounds can
To be removed quickly in adhesive solidification process and VIP manufacturing process, to avoid or reduce to the greatest extent and discharged again in VIP, thus
Guarantee VIP performance most preferably with stabilization.
Constant of dissolution rate of the biosoluble fibres in simulation Human Lung liquid Gamble solution in felt of the invention
It is preferred that Kdis≥100ng/(cm2..hr), it is easier to be dissolved in biological fluid, is unlikely to constitute organism and endanger.Biology can
Dissolve inorfil (including mineral wool, rock wool, mineral wool, glass fibre, refractory fibre, ceramic fibre etc.) each ingredient in fiber
Weight percent also complies with (Na2O+K2O+CaO+MgO+BaO) > 18wt% and [(Na2O+K2O+CaO+MgO+BaO+B2O3)-2*
(Al2O3)] > 40wt%.So felt of the invention effectively can avoid or effectively reduce in manufacturing process, application process and recycling
Fibre dust caused by during dismantling is endangered caused by human health.
Biosoluble fibres play the key effect of skeleton to the manufacture of felt, and the presence of adhesive can make felt be more conducive to make
It makes and applies but be not necessary.When biosoluble fibres in the form of monofilament mutually pass around or overlap or interweave distribution and shape
It at the fibrofelt of sufficient intensity, and is able to satisfy needed for manufacture and application, it may be unnecessary to add adhesive.Work as biosoluble fibres
In the form of monofilament mutually pass around or overlap or interweave be distributed and formed fibrofelt intensity be not able to satisfy manufacture and application needed for,
Then need to add final strength of the adhesive to improve fibrofelt.Adhesive ratio shared in felt should produce intensity meeting
In the case where it is low as far as possible, with reduce adhesive between felt internal fiber abutting edge formed heat transfer and avoid or reduce adhesive
In labile element that may be present release caused gas heat-transfer under vacuum.We are through a large amount of arduous experiment hair
It is existing, when the ratio that adhesive accounts for felt is greater than 15wt%, the area coverage and adhesive of adhesive abutting edge between felt internal fiber
Volume all increase and adhesive in labile element that may be present more discharge under vacuum so that felt is under vacuum
Heat-proof quality is decreased obviously.
