Description
Technical field
The present invention relates to a kind of ultra-fine fibre glass blanket, more particularly, to a kind of hydrophobic type ultra-fine fibre glass blanket.
Background technology
In today's society, glass fibre guard glass fibre cotton is gradually used in building, traffic due to its excellent heat-insulating and sound-absorbing performance
Deng field, a kind of wet extraordinary engineering material, but gradually go deep into the research of people, it has been found that glass fibre guard glass fibre cotton
Water imbibition is serious, ten parts of easy agings, causes greatly to shorten effectively making for glass fibre cotton felted terxture in application process
With the life-span, simultaneously because the moisture absorption can also cause thermal conductivity factor to reduce, sound-absorbing effect reduces and the problems such as material corrosion.Therefore,
The problem of hydrophobicity performance for improving glass fibre guard glass fibre cotton is current in the urgent need to address.
It is well known that the properties of glass fibre have critically important relation, usual fiber with mineral wool filament diameter
Diameter is smaller, and heat-insulating and sound-absorbing performance is more excellent, but hydrophobic type is poorer, and the glass fibre that the country produces at present mainly passes through centrifugation
Prepared by method, have the characteristics of production capacity is high, and product diameter is generally relatively thick, although glass fibre high energy consumption prepared by flame method, but
It is that can prepare the thinner fiber of fibre diameter, effectively improves the properties of glass fibre, but its hydrophobicity simultaneously
It can more be difficult to solve.
The A of Publication No. CN 105152551 Chinese patent discloses a kind of ultra-fine resurrection glass fibre cotton, by alkali-free
Glass fibre cotton, binary glass cellucotton or TERNARY GLASS cellucotton are prepared, wherein, alkali-free glass fibre cotton, binary glass
The diameter of glass cellucotton or TERNARY GLASS cellucotton is respectively less than 4.0um, and fibre length is respectively less than 400mm.Prepared by the invention
The ultra-fine cotton of resurrection glass fibre, softening point is high, thermal conductivity factor is low, flexibility well easily shapes, and preferably remains the original of fiber
Beginning draw ratio can meet severity requirement of the Aero-Space high-end field to insulation material.But glass fibre prepared by this invention
Blanket product does not possess hydrophobic effect as numerous blanket of glass wool products, greatly reduces the service life of product.
The A of Publication No. CN 102875174 Chinese patent discloses one kind, and the present invention relates to a kind of new ceramics fiber
Hydrophobic blanket, new ceramics fiber thermal insulation blanket is used as primary raw material, then using solvent type high-temperature nano hydrophobic material as table
Face inorganic agent, produced by the use of " molecular bridge " or " binding agent " invention for combining silane coupler as fiber and high temperature hydrophobic material
Ceramic fibre hydrophobic blanket there is excellent hydrophobicity, avoid protected outside air water molecule and pipeline it is bad in the case of be incubated
Layer water absorption issue, drastically increases the heat-insulating property of fiber, effectively solves thermal insulator and is corroded problem, while realizes fibre
Blanket integral hydrophobic is tieed up, solves the problem of thermal conductivity factor reduction caused by the conventional fibre blanket moisture absorption, thermal insulator corrosion.But the hair
The high-temperature nano hydrophobic material cost of bright use is higher, although solving the problems, such as hydrophobic, is detrimental to the long-range of fibrous material
Development.
The glass fibre guard glass fibre cotton of domestic production at present is made using centrifugal process mostly, although being obtained in fields such as building, insulations
Extensive use is arrived, but because fibre diameter is not thin enough, shot content is high, and blanket unit weight is larger, hydrophobicity performance is poor etc. lacks
Point causes it can not be used in the heat-insulating and sound-absorbing system of high-end field, and due to the reduction of fibre diameter, unit volume
Interior monfil increasing number, specific surface area improve so that glass fibre guard glass fibre cotton is easier the moisture absorption in wet environment, reduces
The service life of material is shortened while material properties again.Therefore study that a kind of fibre diameter is small, hydrophobicity performance is excellent
Long term growth of the glass fiber material to following heat-insulating and sound-absorbing field it is most important.
