Abstract
The invention provides a dry-process glass cotton and silicon dioxide aerogel composite material and a preparation method thereof. Gaps of glass cotton are filled with silicon dioxide aerogel, and the silicon dioxide aerogel is compounded with the glass cotton through a phenolic resin adhesive to form a fiber and particle composite material; the glass cotton is prepared by a centrifugal blowing process, and a mixture of the phenolic resin adhesive and the silicon dioxide aerogel is sprayed. The composite material is excellent in mechanical performance and good in heat insulation performance and sound absorption performance.
Description
Technical field
The present invention relates to a kind of matrix material and preparation method thereof, particularly a kind of dry method glass wool and silicon dioxide silica aerogel composite material and preparation method thereof.
Background technology
Glass wool is that unorganic glass meltblown is formed, because thering is good rebound resilience, heat insulating effect is excellent, also has very excellent damping, sound absorption characteristics, is conducive to reduce sound pollution, improve Working environment, be widely used in architecture indoor, sound-attenuating system, the vehicles, refrigeration equipment, the damping of household electrical appliance, sound absorption, noise reduction process, effect is very good.The production of glass wool is mainly divided into flame winding-up and centrifugal winding-up, but flame winding-up energy consumption is higher, is centrifuged gradually blowing process and replaces.In the preparation technology of glass fiber blanket, be mainly divided into wet method and dry method.The cotton felt unit weight of wet production is higher, compound wet processings that adopt of general fiber and particle more; Dry process felt mainly adopts binding agent that fiber is solidified into felt.
Aerosil has nano-porous structure, general aerosil density is lower, there is special porous network structure, porosity is more than 90%, most of gas cell distribution is below 50nm, be less than the mean free path 70nm of air molecule, between air molecule, be difficult to bump, there is lower thermal conductivity.The preparation method of aerogel composite is mainly divided into two kinds, is respectively gel molding in integral and grain forming method.For gel molding in integral, in sol-gel process, introduce wild phase, finally obtain Monolithic aerogel matrix material; For grain forming method, the nano-hole aerogel particle powder preparing is added in wild phase and binding agent, by mold pressing or casting, make the complex body of post forming.
The present invention utilizes glass wool, resol and aerosil to prepare fiber, particulate composite.This invents wet processing different from the past, utilizes dry process that the excellent properties of white rouge aerogel particle and glass wool is integrally combined, and makes matrix material not only have lightweight, the characteristics such as calorifics, acoustical behavior excellence.
Summary of the invention
Object of the present invention is intended to overcome the deficiencies in the prior art, and a kind of dry method glass wool and silicon dioxide silica aerogel composite material and preparation method thereof are provided.
For realizing the technical scheme of object employing of the present invention, be: a kind of dry method glass wool and silicon dioxide silica aerogel composite material and preparation method thereof are provided, it is characterized in that aerosil is filled in glass wool gap, by phenolic resin adhesive, aerosil and glass wool are carried out compoundly, form fiber and the compound matrix material of particle.The preparation method of this dry method glass wool and silicon dioxide silica aerogel composite material, mainly comprises the following steps:
(1), by the aerosil aqueous solution, deposit in hold-up vessel;
(2) formulated phenolic resin binder solution, adds appropriate Na2SO4 solidifying agent, forms transparent redness or light red solution, and deposits in resin container;
(3) utilize resin extraction pump that the phenolic resin adhesive solution in the aerosil aqueous solution in hold-up vessel and resin container is drawn in mixing tank, stir;
(4) utilize centrifugal injection method, prepare glass wool, in the process of descending slowly and lightly, through spray ring, spray aerosil and phenolic resin adhesive mixed solution;
(5) descend slowly and lightly in the glass wool becoming on lace curtaining, through tape transport, enter curing oven, under high temperature, extruding condition, prepare glass wool and silicon dioxide silica aerogel composite material.
In step (4), in described aerosil and phenolic resin adhesive mixed solution, the concentration of resol is 0～10%; In step (5), described solidification value is 180～240 °.
The present invention compared with prior art, has the following advantages:
(1) in dry method glass wool and silicon dioxide silica aerogel composite material, adopt resol that glass wool and silica dioxide granule is compound, increased the strength of joint between fiber and particle, improved mechanical property.
(2) adopt dry process to prepare fiber, particulate composite, can prepare the cotton felt that unit weight is lighter.
