Description
Technical field
The present invention relates to a kind of making method of insulated panel core material, is that a kind of employing glass fibre is that raw material is made insulated panel core material method specifically.
Background technique
At present, vacuum heat-insulating plate has applied to every field, and it has met customer requirement with the characteristic of energy-conservation, low-carbon (LC), environmental protection, safety.In order to reach every characteristic of vacuum heat-insulating plate, selecting with making method of the inner core of vacuum heat-insulating plate is very large on its impact, core is generally selected porous media material, as aerogel, microvoid polyurethane, SiO 2 powder, asbestos fiber, glass fibre etc.For core material of vacuum heat insulation plate, must possess following four specific characters: 1, under high vacuum negative pressure state, vacuum heat-insulating plate is had to supporting effect, prevent that vacuum heat-insulating plate from shrinking, caving in; 2, to reduce as much as possible heat conduction and occur, extend 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.
Current different due to the selection of material and making method of core material of vacuum heat insulation plate, the field that different cores uses is different, for household electrical appliances insulation, the long-distance transport insulations such as refrigerator etc., require resistance good in thermal property, thermal conductivity is low, but the thermal conductivity of the exhausted plate of most vacuum is all between 0.01-0.02W/m.K, and core material of vacuum heat insulation plate is bulky, thickness generally between lcm-5cm, thereby affected the heat insulation effect of household electrical appliances insulations, long-distance transport insulation etc.For as: household electrical appliances insulations, long-distance transport are incubated these field of thermal insulation, require the thermal conductivity of vacuum heat-insulating plate more low better, and the thickness of the vacuum heat-insulating plate simultaneously using is got over Bao Yuehao.
Summary of the invention
Goal of the invention: the object of the invention is in order to overcome the deficiencies in the prior art, a kind of High Performance Adiabatic board core material making method is provided.
Technological scheme: in order to solve the problems of the technologies described above, the invention provides a kind of insulated panel core material making method, the concrete steps of the method are as follows:
(1) prepare raw material, select cullet 65-75 mass parts, feldspar powder 6-9 mass parts, calcium oxide 4-6 mass parts, boron magnesium ore deposit 15-20 mass parts, mix;
(2) founding and fibrosis of raw material, obtains 1.5-3 microns of diameters, the glass fibre that length is 3-5 millimeters;
(3) glass fibre of step (2) is pulled an oar, is shaped to glass fibre core blank;
(4) use pressure roller to carry out surfacing to glass fibre core blank;
(5) the glass fibre core blank dewatered drying to shaping;
(6) finished product cuts.
Preferably, said the founding 1200 ℃ of-1400 ℃ of temperature of step (2) carried out.
When preferably, step (3) is pulled an oar, glass fibre is added to water agitation and dilution concentration to 0.3-0.6%, more preferably diluted concentration to 0.55%.
Preferably, step (4) adopts pressure roller to carry out vertical and horizontal surfacing to glass fibre core blank, its thickness is adjusted simultaneously, more preferably adopts twice pressure roller to the smooth 3-8mm of being of glass fibre cotton core blank thickness.
Preferably, the bake out temperature of step (5) is 250-360 ℃, and drying time is 3-15 minute.
Preferably, the size that in step (6), finished product cuts is 5mm X 5mm or 8mm * 5mm
Beneficial effect: insulated panel core material of the present invention has the following advantages:
1, making method technique of the present invention is simple, adapts to industrialized production.
2, the insulated panel core material thermal conductivity that the present invention produces is low, can reach 0.025-0.003W/m.k: core thickness is thin simultaneously, only has 3-8mm, can be used for the field of thermal insulation such as high-end household electrical appliances insulation, long-distance transport: use the vacuum heat-insulating plate of the core making of the present invention's production on quality and performance, to occur qualitative leap, between the household electrical appliances hollow of equal volume, utilization rate is larger, and same long-distance transport can utilize space larger.
