Abstract
The invention discloses centrifugal glass wool for a vacuum thermal-insulation board core material. The centrifugal glass wool is prepared by a centrifugation blowing method, has rounded glass fiber sections, smooth fiber surfaces and no obvious concave-convex structure on the surface. The centrifugal glass wool has centrifugal glass wool density of 60-200kg/m<3>, wherein more than 80% of the centrifugal glass wool has density of 80-150kg/m<3>. The centrifugal glass wool has average fiber length of 10-25mm. The centrifugal glass wool has smooth fiber surfaces and no obvious contact between fibers, reduces fiber overlap joint by concave-convex structure reduction thereby reducing thermal conduction, and further guarantees very low thermal conduction coefficients of a core material and a vacuum thermal-insulation board prepared from the centrifugal glass wool.
Description
Technical field
The present invention relates to a kind of centrifugally glass-wool, is a kind of core material of vacuum heat insulation plate centrifugally glass-wool specifically.
Background technology
Super glass wool is as the fibrous novel receiving material of one, and it has lightweight, insulation, fire prevention, sound-absorbing, the high-performance such as mothproof, anticorrosion, is widely used in chemical industry, metallurgy, light industry, electric power, oil and building trade.
Vacuum heat-insulating plate is with beta glass fibre etc. for core material, using plastic-aluminum combined film as packaging bag, and the high-efficiency insulated sheet material obtained after Vacuum Package.Manufacture good evacuated panel, its thermal conductivity only has 0.004 W/ (mk), and compared with conventional lagging material, vacuum heat-insulating plate has extremely excellent heat-insulating property.
The high-performance of super glass wool is the prerequisite ensureing core and vacuum heat-insulating plate high thermal insulation.Irregular, too coarse, the density unevenness of staple all can affect its heat conductivility, and bring great impact to product.
Summary of the invention
Object of the present invention is intended to the deficiency overcome in prior art, and provide a kind of core material of vacuum heat insulation plate centrifugally glass-wool, this glass wool is made up of centrifugal injection method, it is characterized in that this centrifuging glass fibre cross section is for circular.
Described centrifugally glass-wool, is characterized in that this centrifugal glass fibre smooth surface, without obvious concaveconvex structure; Centrifugal cotton density is 60 ~ 200 kg/m
3, wherein the centrifugal cotton density of more than 80% is 80 ~ 150 kg/m
3, its average fiber length is 10 ~ 25mm.
Compared with prior art, advantage of the present invention and positively effect are: glass wool smooth surface of the present invention, without obviously contacting between fiber with fiber, the minimizing of concaveconvex structure can reduce the overlap joint between fiber, thus reduction thermal conduction, further ensure use the core prepared of this glass wool and heat conductivity of vacuum insulation panel extremely low.
Accompanying drawing explanation
Fig. 1 is a kind of cross section is circular centrifuging glass fibre;
Fig. 2 is the centrifugally glass-wool that a kind of fiber surface is smooth.
Embodiment
Below in conjunction with specific embodiment, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims and limited.
