Description
Technical field
The invention belongs to heat-insulating heat-preserving material fields, and in particular to a kind of preparation method of anti-picking aerogel blanket.
Background technique
Currently, tapping a new source of energy, improving existing energy utilization rate and the energy saving great attention for having caused various countries.China
It is the barren country of an energy, therefore, reasonable energy utilization, the energy saving sustainable development to Chinese society have important
Meaning.It employs new technology, the heat-insulating heat-preserving material that new process development is environmentally friendly is energy saving most effective, most economical
One of measure.
SiO2For aeroge as a kind of emerging ultra heat insulating material, thermal coefficient is extremely low, static far below under room temperature
The thermal coefficient of air 0.25W/mK, with the incomparable heat insulation and preservation effect of other materials, and density is low, anti-water resistance
Combustion, environmentally protective, anticorrosion, non-aging, long service life, referred to as super heat preserving and insulating material.It is currently used primarily in work
The insulation in the fields such as industry pipeline, industrial furnace body, survival capsule, communications and transportation, household electrical appliance, glass.But due to its preparation
The reason of method, SiO2Aerogel blanket generally existing felt body in transport, construction and use process fall off airsetting rubber powder the case where,
Picking situation not only brings inconvenience to construction, brings threat to construction personnel's health, while can also reduce aerogel blanket sheet
The performance of body.Therefore under the premise of guarantee aerogel blanket good heat preservation and insulation, a kind of aeroge not lost powder is developed
Composite material guarantees the health of production, user of service, and the various demands for meeting market are very important.At present usually
Anti- picking scheme is to stick on aeroge fibrofelt surface using glass-fiber-fabric, aluminium foil cloth etc., and this mode high labor cost is unfavorable
In large-scale production, and front and back sides stick the flexible of rear material and reduce, and bad curling, bending, storage and transportation, construction and installation are not square enough
Just.The coat preparing technology on aerogel blanket surface is one of the method for avoiding it from losing powder developed recently.It is typically employed in airsetting
Glue surface coats solvent based coating with anti-slag-falling, and solvent based coating one can bring environmental pollution, in addition will lead to solvent infiltration
It penetrates into inside aeroge, destroys pore structure, reduce its heat-proof quality.
Summary of the invention
The purpose of the present invention is to provide a kind of preparation methods of anti-picking aerogel blanket.
To achieve the above object, the technical solution adopted by the present invention is as follows:
A kind of preparation method of anti-picking aerogel blanket, steps are as follows:
(1), it takes positive esters of silicon acis, second alcohol and water to be uniformly mixed, sequentially adds NH later4F solution and ammonium hydroxide stir evenly, and obtain two
Silica sol；Wherein, with molar ratio computing, positive esters of silicon acis: ethyl alcohol: water=1: (4 ~ 12): (2 ~ 4)；NH4The additional amount of F solution is protected
Card is with molar ratio computing, NH4F: positive esters of silicon acis=(0.002 ~ 0.01): 1；The additional amount of ammonium hydroxide guarantees with molar ratio computing, NH3: positive silicon
Acid esters=(0.005 ~ 0.015): 1；
(2), after fibrofelt being impregnated in the silicon dioxide gel obtained by step (1), static 8 ~ 24 h of aging at 30 ~ 60 DEG C；
(3), fibrofelt obtained by step (2) is subjected to hydrophobically modified processing, then carries out solvent displacement, re-dry with dehydrated alcohol
Processing, obtains aerosil felt；
(4), aerosil felt obtained by purge step (3) removes floating powder on surface；
(5), radiation treatment is carried out to the tow sides of aerosil felt obtained by step (4) respectively as electron beam；
It is (6), dry by the tow sides of Aqueous Adhesives difference even application aerosil felt obtained by step (5),
Up to anti-picking aerogel blanket.
Preferably, in step (1), the positive esters of silicon acis is ethyl orthosilicate or methyl orthosilicate.
Preferably, in step (2), the time of fibrofelt impregnation of silica colloidal sol is 12 ~ 24 h.
Preferably, in step (3), fibrofelt obtained by step (2) is placed in modification liquid carry out hydrophobically modified processing 12 ~
24 h, the modification liquid are modifying agent and dehydrated alcohol in molar ratio 1: the mixed liquor of (2 ~ 5) composition, the modifying agent are pregnancy
Base disiloxane or trim,ethylchlorosilane.
Preferably, in step (3), the displacement number of dehydrated alcohol is 2 ~ 3 times, and the time replaced every time is 12 ~ 36 h.
Preferably, in step (5), the irradiation dose of electron beam is 1 ~ 5 kGy, and the time is 1 ~ 5 min.
Preferably, in step (6), the Aqueous Adhesives are aqueous acrylic emulsion, water-and acrylate lotion, aqueous
Polyaminoester emulsion or aqueous epoxy resin emulsion, the range of viscosities of Aqueous Adhesives are 70 ~ 80 Pas.
The present invention prevents the de- of felt body surface particles by coating Aqueous Adhesives on aerosil felt surface
It falls, since aerosil felt passes through silicic acid anhydride, when its surface sprays Aqueous Adhesives, it is difficult to ensure that aqueous viscous
Knot agent is uniformly sprawled on its surface, and the method that the present invention uses electron beam to irradiate aerosil felt surface makes
Aerosil felt surface hydrophilic, and then be conducive to Aqueous Adhesives sprawling on aerosil felt surface, into
And the occurrence of preventing picking, while the heat-proof quality of aerosil felt will not be caused brokenly because infiltration is too deep
It is bad, dust pollution question of the aerosil felt in storage and transportation, installation, use process can be overcome.
