Description

A kind of mist sealing material and preparation method thereof
Technical field
The present invention relates to road maintenance field of material technology, be specifically related to a kind of mist sealing material and system thereof Preparation Method.
Background technology
After bituminous paving normally uses several years, road surface starts slight fatigue cracking occur, lose thin bone The phenomenon of material, and its seepage of water is greatly improved, and road surface water can be through crack or fine aggregate injury region (dew At bone) enter in asphalt, this has further speeded up the damage on road surface.At this moment the phase, road Face is in the most intact period, if processed the most in time in this period, can cause check crack, Testudinis Split, the pavement destruction such as pit-hole.How processing the above defect, method is a lot, as micro- At table, thin cover etc., be all respectively arranged with pluses and minuses, but sum up, in this stage, maximally effective side Method is " mist sealing covers " i.e. " FOG SEAL ", and its expense is the cheapest.
Mist sealing sprays the special Colophonium of thin layer, high osmosis on asphalt surface course, with shape Become one layer of tight waterproof layer to be closed on road surface, play water proof antiseepage, the function on protection road surface, maximum Limit ground reduce road surface water destruct, increase road surface gather materials between cohesive force, prolonging service life of pavement. Can be used for the loss of light to moderate fines or loose road, the renewable and old oxidized asphalt road of protection Face, fills up small-sized crack and surface void, deepens the color of bituminous paving, strengthens bituminous paving and mark The road that the contrast of line, road that either volume of traffic is little or the volume of traffic are big all can use.Mist seals Layer is as highway early prevention maintenance most efficient method, at 2004 year " Second Committees Whole nation Highway science and technology innovation Forum " on, using it as maintenance new technique, promote in the whole nation.Warp After mist sealing, owing to material therefor mobility is bigger, can penetrate in aggregate seam, can be flowed into In crack, road pavement "blood transfusion", thus recover road table asphalt adhesive power, fill up minute crack and Space, prevents road table from oozing under water, and Pavement Performance maintains the 2-3 year, postpones cost higher foster Nurse's journey, improves the economic benefit of road.
There are many mist sealing materials, such as Application No. 201110335727.1 both at home and abroad at present Chinese patent discloses a kind of composite seal coat for maintenance of surface, described composite seal coat two-layer altogether, bag Including the sand bed of material and emulsified bituminous materials layer, original road surface is composite seal coat carrier, but due to employing Sand material is relatively thick, and common emulsified asphalt adheres to poor, is easily ground off by driving, carries after using a period of time Walking, using effect is poor;And for example the Chinese patent of Application No. 201110212884.3, uses The preferable epoxy resin of caking property is as modifying agent, but owing to not adding skid resistance fine sand and water-resistance Material, can cause water-resistance and antiskid hydraulic performance decline;And for example Application No. 201210219467.6 and The Chinese patent of Application No. 201010567413.X with the addition of bitumen regenerant, but does not add viscous Knot property and skid resistance material, all can affect road effect.
The research of mist sealing material at present makes progress in two directions always, is on the one hand from material Use the higher binding material of adhesiveness on material, on the other hand be improve from technique binding agent and sand grains it Between wrap performance.Water-based material is to study new focus, such as aqueous polyurethane at present in road surface application, Having anionic, cationic and nonionic three types, in film forming procedure, moisture is gradually arranged Remove, between molecule, crosslink reaction, form network structure, not only there is more preferable environmental-protecting performance, And there is hardness height and high resilience, adhesion is strong, and oil resistant is waterproof waits premium properties, in coating work Industry application playing great function, if being applied in mist sealing covers, the biggest warp will have been brought Ji benefit and application prospect.
In sum, the most all there is wearability and lack poor with road surface adhesiveness in a lot of materials Point, for improving mist layer sealing shortcoming, also has the biggest research space.
Summary of the invention
It is an object of the invention to there is the shortcoming such as adhesiveness, skid resistance difference for the current mist sealing material of solution And technical barrier, it is provided that a kind of mist sealing material and preparation method thereof.
