Description
Technical field
The present invention relates to a kind of core material of vacuum heat insulation plate and preparation method thereof, be specifically a kind of be the method that raw material is made insulated panel core material with the glass fibre cotton.
Background technique
At present, vacuum heat-insulating plate has applied in the every field, and it satisfies with the characteristic of energy-conservation, low-carbon (LC), environmental protection, safety
Customer requirement.Can know with practical operation through investigation, vacuum heat-insulating plate inside core select for use with making method to tool each item property
Can the influence very big, core-as select porous media material for use, like aerogel, little { L polyurethane, SiO 2 powder, asbestos fiber, glass fibre etc.The against vacuum insulated panel core material must possess following four specific characters: 1, under the high vacuum negative pressure state, vacuum heat-insulating plate is had supporting effect, prevent that vacuum heat-insulating plate from shrinking, caving in; 2, to reduce heat conducting generation as much as possible, prolong heat conducting path; 3, must possess open-celled structure, gas can be discharged with prestissimo under negative pressure state; 4, material need possess and prevents thermal-radiating performance.
At present because of different types of vacuum heat-insulating plate application is different, the selection of its core is difference to some extent also, requires to hinder good in thermal property for household electrical appliances insulation, building exterior wall heat preserving etc.; Thermal conductivity is low; The thermal conductivity of the exhausted plate of present most of vacuum is all between 0.01-0.02W/m.K, and core material of vacuum heat insulation plate is bulky, and thickness is generally between lcm-5cm; After being used for household electrical appliances insulations, building exterior wall heat preserving, space capable of using and the insulation life-span of having reduced household electrical appliances, building are short.So, hope that the attenuation of vacuum insulation plate thickness, thermal conductivity reduce to household electrical appliances and building exterior wall heat preserving, reduce the cost of production of vacuum heat-insulating plate simultaneously, these are real to be the current problem that needs research.
Summary of the invention
Goal of the invention: the objective of the invention is in order to overcome the deficiency of existing technology, low core material of vacuum heat insulation plate such as a kind of cost that is used for household electrical appliances insulation, building exterior wall heat preserving etc. and preparation method thereof is provided.
Technological scheme: in order to solve the problems of the technologies described above; The invention provides---planting by diameter is 3.5-5um; Length is that glass fibre cotton and the diameter that 5-20mm centrifuge method is produced is 1.5-2.5um; Length is that the glass fibre cotton that 1-5mm flame method is produced is mixed and made into: the glass fibre cotton that said flame method is produced accounts for 70wt%, and the glass fibre cotton that said centrifuge method is produced accounts for 30wt%.
Because what adopt during centrifuge method is produced all is discarded cullet, cost of material is low, the diameter 35 that produces simultaneously-
5um, the glass fibre cotton of length 5-20mm use the relative cost of manufacturing mechanism low, so the glass fibre cotton cost that obtains is low, thereby adopt diameter 3.5-5um, and the vacuum heat-insulating plate cost that the glass fibre cotton of length 5-20mm is made is low.
And the glass fibre cotton that adopts flame method to make, diameter is short, and the glass fibre cotton density that obtains is bigger, and the core material of vacuum heat insulation plate thermal conductivity of processing is lower, but the glass fibre cotton manufacturing cost that adopts flame method to produce is high.
The concrete steps that the invention also discloses a kind of this making method of manufacture method of core material of vacuum heat insulation plate are following:
(1) cut-off directly is 3.5-5um, and glass fibre cotton and diameter that length is produced for the 5-20mm centrifuge method are 1.5-2.5um, and length is the glass fibre cotton that 1-5mm flame method is produced; The glass fibre cotton that said flame method is produced accounts for 70wt%, and the glass fibre cotton that said centrifuge method is produced accounts for 30wt%;
(2) two kinds of glass fibre cottons added to send into after water stirs join stock tank dilution, diluted concentration to 0.3-0.6%:
(3) will dilute good glass fibre cotton slurries sends into and holds stock tank;
The slurry that (4) will hold in the stock tank is sent into breast box, adopts forming net to the glass fibre cotton moulding of dewatering then, processes glass fibre cotton core blank;
(5) adopt pressure roller to glass fibre core blank carry out vertically, lateral surfaces is smooth, simultaneously the thickness of glass fibre core blank adjusted, and makes glass fibre core blank thickness unanimity;
(6) environment that the glass fibre core blank that will accomplish shaping is put into negative pressure of vacuum with glass fibre core blank 60%-
70% moisture removal;
(7) the glass fibre core blank that will remove 60%-70% moisture is then sent into baking and curing in the roasting chamber, and baking the temperature inside the box is controlled at 250-400 degree centigrade, and stoving time is 3-15 minutes; After accomplishing, baking forms the whole plate of glass fibre core;
(8) then the whole plate of glass fibre core is cooled to normal temperature;
(9) according to customer requirement the whole plate of glass fibre core is carried out cutting, the glass fibre core of the standard that completes.
Glass fibre core blank thickness is 0 5-30mm in the step described in the present invention (5).Because making the glass fibre cotton of central layer employing is that diameter is 3.5-5um, length is the glass fibre cotton that the 5-20mm centrifuge method is produced, and said glass fibre core blank optimum thickness is 0.5-8mm.
When (4) forming net dewaters to glass fibre cotton in the step described in the present invention, the speed of forming net be 2-5 rice/minute.Adopt in the glass fibre cotton core blank that this speed can effectively guarantee to produce through forming net glass fibre cotton density even, integral thickness is even relatively, does not occur high low situation on one side on one side, has improved the core material of vacuum heat insulation plate of producing
End product quality.
Beneficial effect: core material of vacuum heat insulation plate according to the invention has the following advantages:
1, adopt glass fibre cotton that glass fibre cotton that 30 wt% centrifuge method produce and 70 wt% flame method produce as the core material of vacuum heat insulation plate raw material among the present invention, the vacuum heat-insulating plate of producing; The core thermal conductivity is at 0.0025-0004W/m; K; Its heat insulating coefficient with respect to the glass fibre cotton that adopts 100% flame method to produce be the core material of vacuum heat insulation plate of raw material high 0.0005 W/m.k; The heat insulation effect influence is little, the manufacture cost of but having practiced thrift core material of vacuum heat insulation plate greatly; And the thickness of core for o.5-8mm, thickness and the glass fibre cotton that adopts 100% flame method to produce are that the core material of vacuum heat insulation plate of raw material is more or less the same.
2, core material of vacuum heat insulation plate according to the invention has open-celled structure speed exhaust performance.
3, the glass fibre cotton that centrifuge method is produced among the present invention has flame retardant property, and the vacuum heat-insulating plate using scope of producing is extensive.Can satisfy sound-absorbing, nontoxic, environmental protection requirement.
4, process for integrally manufacturing of the present invention is simple, adapts to industrialized production.
