Description
Technical field
The present invention relates to a kind of cold-patch liquid of asphalt roads, more particularly to a kind of modified polyurethane cold-patch liquid, preparation
Method and using method.
Background technology
The construction of traditional hot patching is for place dispersion, and the little pavement maintenance of quantities is inconvenient, and can not be
Sleety weather normal construction.Cold-patch method has relatively well made up the deficiency of hot method, it is adaptable under any weather and environment, repairs each
Different types of road deck is planted, therefore the application in terms of road maintenance increases year by year.
Common cold-patch liquid, often initial strength is not high, and the later stage is strong due to can not quickly be formed because diluent volatilization is slow
Degree, after open to traffic, easily occurs again that loose, the disease such as come off, and useful life longevity is poor, can only be used as the interim of disease
Handle measure.
Asphalt modification is studied both at home and abroad, modified pitch is that modifying agent is added in Colophonium, makes Colophonium or Colophonium
The performance of compound is improved.Wherein, modifying agent mostly is：Rubber, resin, high molecular polymer, levigate rubber powder or its
His filler etc..The shortcoming of this bitumen modifying process is：It is total to due to simply simply physics will be carried out in modifying agent addition Colophonium
It is mixed, thus be also easy to produce the problem of isolation layering and strong for the temperature sensitive property of Colophonium, viscosity is low, pliability is poor etc. asks
Though topic has improvement, effect is undesirable.
Chinese invention patent CN201210307108.6, discloses a kind of preparation method of polyurethane-modified Colophonium, it
Under initiator effect, Colophonium and 1-propenol-3 reaction are prepared into hydroxyl Colophonium, then reacted with isocyanates, be obtained polyurethane-modified
Colophonium.The shortcomings of simply improving the low temperature embrittlement of Colophonium, pliability difference.But bitumen construction performance and other performances are without basic
Change.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of modified polyurethane cold-patch liquid, preparation side
Method and using method, can quickly form high intensity, improve durability.
The present invention is achieved by the following technical solutions：A kind of modified polyurethane cold-patch liquid of the present invention, by weight, bag
Include 100~140 parts of polyisocyanates, 80~150 parts of polyether polyol, 80~150 parts of PEPA, SBS resins 10~15
Part, 0.03~0.15 part of catalyst, 200~300 parts of diluent, 20~40 parts of plasticizer, 0.5~1 part of defoamer.
The polyisocyanates is selected from aromatic polyisocyanate, aliphatic polyisocyante fat, ring race polyisocyanates
In one or more.
The polyether polyol is selected from Polyethylene Glycol, polyoxypropyleneglycol, polytetrahydrofuran diol, tetrahydrofuran-oxygen
Change at least one in propylene copolymer glycols, polybutadiene diol, polybutadiene PTMEG, Polybutadiene-acrylonitrile glycol.
The PEPA is selected from 10PE27 glycol, polyadipate ethylene glycol and 1,2-propylene glycol esterdiol, gathers
Adipic acid diglycol esterdiol, poly- carbonic acid 1,6-HD esterdiol, polycaprolactone glycol, polyadipate -1,4- fourths
At least one in glycol esterdiol.
The diluent is selected from acetone, butanone, butanone, dioxane, N, N- dimethylformamides, N- crassitudes
Ketone, ethyl acetate, methyl acetate, ethyl ester butyl ester, toluene, dimethylbenzene, dichloromethane, carbon tetrachloride, dichloroethanes, gasoline, coal
At least one in oil, diesel oil.
The plasticizer is selected from aliphatic dibasic acid ester, Phthalates, many esters of gallic acid of benzene, benzoates, many
At least one in first alkoxide, chlorinated hydrocarbons, citric acid ester type, polyesters.
The defoamer disappears selected from disappear silicone defoamer, polyether antifoam agent, polyether modified polysiloxan defoaming agent, higher alcohols
At least one in infusion.
The SBS resins type SBS mean molecule quantity 8~120,000.It it is 10~15 parts by mass fraction.
The catalyst includes that organic tin, amine are chosen any one kind of them or two or more.
The cold-patch liquid is viscous solution, and density is 1.1~1.2g/cm3, solid content is 30~85%, and viscosity is at 25 DEG C
For 5000~8000mPas-1。
A kind of preparation method of modified polyurethane cold-patch liquid, comprises the following steps：
(1) by polyether polyol or PEPA, asphalt heating to 110~120 DEG C, in 0.06~0.08MPa vacuum
Under degree, 2~3h is dehydrated, when the mass fraction of moisture is less than or equal to 0.05% in polymer polyatomic alcohol, is cooled to 40~50 DEG C,
