Abstract
The invention discloses a method for making a high-performance vacuum heat insulating plate core material. The method comprises the following steps of: pulping of glass fiber wool produced by a flame method, thinning, netting, dehydration molding, pressure roller sizing, vacuum negative pressure dehydration, drying, cooling and cutting. Because the glass fiber wool produced by the complete flame method is used as a raw material of the high-performance vacuum heat insulating plate core material, the heat conduction coefficient of the produced vacuum heat insulating plate core material is 0.025 to 0.003W/m.k.
Description
Technical field
The present invention relates to a kind of preparation method of core material of vacuum heat insulation plate, is that a kind of glass fibre cotton that adopts is the preparation method of raw material specifically.
Background technology
At present, vacuum heat-insulating plate has applied in the every field, and it has satisfied customer requirement with the characteristic of energy-conservation, low-carbon (LC), environmental protection, safety.In order to reach each item characteristic of vacuum heat-insulating plate; Selecting for use with preparation method of the inner core of vacuum heat-insulating plate is very big to its influence; Core is generally selected porous media material for use, like aeroge, microvoid polyurethane, SiO 2 powder, asbestos fibre, 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 role, prevent that vacuum heat-insulating plate from shrinking, caving in; 2, to reduce heat as much as possible and be transmitted to generation, 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 core material of vacuum heat insulation plate is because material chosen and preparation method different; The field of the vacuum heat-insulating plate utilization that different cores produces is different, requires the resistance good in thermal property for the insulation of household electrical appliances such as refrigerator, long-distance transport insulation etc., and thermal conductivity factor is low; But the thermal conductivity factor 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, thickness generally between 1cm-5cm, thereby influenced the heat insulation effect of household electrical appliances insulations, long-distance transport insulation etc.For as: household electrical appliances insulations, these field of thermal insulation of long-distance transport insulation hope that the thermal conductivity factor of vacuum heat-insulating plate is low more good more, and the thickness of the vacuum heat-insulating plate that uses is simultaneously got over Bao Yuehao.
Summary of the invention
Goal of the invention: the objective of the invention is in order to overcome the deficiency of prior art, a kind of manufacture method of core material of vacuum heat insulation plate that applies to fields such as household electrical appliances insulation, long-distance transport insulation is provided.
Technical scheme: in order to solve the problems of the technologies described above, the concrete steps that the invention provides a kind of this preparation method of high-performance manufacture method of core material of vacuum heat insulation plate are following:
(1) cut-off directly is 1.5-2.5um, the glass fibre cotton that length is produced for the 1-5mm flame method;
(2) glass fibre cotton is added to send into after water stirs join stock tank dilution, diluted concentration is 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 flow box, adopts forming web to the glass fibre cotton moulding of dewatering then, processes glass fibre cotton core blank;
(5) adopt pressure roller to glass wool core blank carry out vertically, lateral surfaces is smooth, simultaneously the thickness of glass wool core blank adjusted, and makes core blank thickness unanimity;
(6) the glass wool core blank that will accomplish shaping is put into the moisture removal of the environment of negative pressure of vacuum with glass wool core blank 30%-40%;
(7) the glass wool core blank that will remove the moisture of 30%-40% is then sent into baking and curing in the baking box, and baking the temperature inside the box is controlled at 250-360 degree centigrade, and stoving time is 3-15 minute; After accomplishing, baking forms the whole plate of glass wool core;
(8) then the whole plate of glass wool core is cooled to normal temperature;
(9) according to customer requirement the whole plate of glass wool core is carried out cutting, complete meet the requirements of the customers the glass wool core.
Glass wool core blank thickness is 0.5-0.8mm in the step described in the present invention (5).
When (4) forming web dewaters to glass fibre cotton in the step described in the present invention, the speed of forming web be 3-5 rice/minute.Adopt in the glass fibre cotton core blank that this speed can effectively guarantee to produce through forming web 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 end product quality.
The microglass fiber that flame method is produced among the present invention promptly adopts burner blowing process to produce glass wool.
Beneficial effect: core material of vacuum heat insulation plate according to the invention has the following advantages:
1, the glass wool that adopts the production of 100% flame method among the present invention has open-celled structure as high-performance core material of vacuum heat insulation plate raw material, can satisfy the quick exhaust performance that core material of vacuum heat insulation plate possesses.
2, the glass wool that adopts the production of 100% flame method among the present invention is as high-performance core material of vacuum heat insulation plate raw material; Its fibre diameter is thin, and surface area is big, has reduced the ratio of vertical fibers; Prolong the heat conducting path of solid, thereby lowered the pyroconductivity of core greatly;
3, that the glass wool that flame method is produced among the present invention has is fire-retardant, sound-absorbing, characteristic nontoxic, environmental protection make the vacuum heat-insulating plate scope of application of producing extensive.
4, integral production method technology of the present invention is simple, adapts to suitability for industrialized production.
5, the core material of vacuum heat insulation plate thermal conductivity factor produced of the present invention is low, can reach 0.025-0.003W/m.k; Core thickness is thin simultaneously has only 0.5-0.8mm, can be used for field of thermal insulation such as high-end household electrical appliances insulation, long-distance transport; The vacuum heat-insulating plate that the core that utilization the present invention produces is made qualitative leap occurred on quality and performance, utilization rate is bigger between the household electrical appliances hollow of equal volume, and same long-distance transport space capable of using is bigger.
