Description
[technical field]
The present invention relates to the water-proof adhesive that a kind of road and bridge is used, relate in particular to a kind of polymer-type water-proof adhesive of handling through modification.
[background technology]
Asphalt is to be widely used on the road of routine, develop sophisticated operating technique very, but on bridge floor, mat formation bituminous pavement with on the road surface be two notions inequality fully; Making bituminous pavement on sub-surface, road surface and sub-surface are organic wholes, bear jointly and rationally divide equally the vehicle ' load-carrying; The situation of bridge floor is then different therewith, and bituminous pavement is laid on the rigidity basal plane, and the Young's modulus of cement concrete and bituminous concrete differs hundreds of times; And asphaltic road-mix surface course is in pressured state basically; The major cause that the road surface is damaged no longer is that tensile stress causes, and only possibly be the slippage that causes of the disengaging between two-layer up and down and come off, and it is layer thin more to mat formation; Problem is serious more, so interlayer combines most important.
In order to improve the road and bridge waterproof quality, improve the have effective adhesive of bituminous pavement to concrete foundation, reduce that bridge is not done waterproof or the water-proof material that adopts is improper causes infiltration; Make steel bar corrosion; The layer of mating formation peels off, alkali-aggregate reaction, the badly damaged problems such as concrete expansion that caused by the steel bar corrosion face; The soundness and the work-ing life of bridge have been had a strong impact on, the comfortableness of driving and security.
[summary of the invention]
The present invention is directed to above problem and proposed the preparation method of the sticker that a kind of water resistance is good, resistance to shear is strong; This sticker is applicable to that basal plane is that Portland Cement Concrete Surface Course is a bituminous concrete; Have good ductility and concrete stronger cohesive force is arranged, and proposed the method for spraying adhesive.
Technical scheme of the present invention is: a kind of preparation method of bridge water-proof adhesive; It is characterized in that said bridge water-proof adhesive is to be processed by the skimmer that the coumarone indene resin solution that massfraction is the liquid modifying petroleum pitch solution of 25%-35%, thermoplastic styrene butadiene rubber solution that massfraction is 60%-70%, massfraction is 4%-9.7%, flow agent that massfraction is 0.2%-0.4% and massfraction are 0.1%-0.2%:
Wherein to adopt massfraction be that the polymer modification petroleum pitch of 60%-70% and trieline that massfraction is 30%-40% are processed to liquid modifying petroleum pitch solution; At first polymer modification petroleum pitch is placed in the reaction vessel and heats, when reaching 160 ℃ of temperature, constant temperature was preserved 60-90 minute; Taking-up is inserted in the stirred vessel and is stirred; Stirring velocity is 300 commentaries on classics/min, then load weighted trieline is slowly poured in the polymer modification petroleum pitch in the whipping process, continues to stir 10-20 minute; Become mixed uniformly thick liquid under the apparent state, taking-up seals subsequent use;
Wherein the thermoplastic styrene butadiene rubber solution N-BUTYL ACETATE that adopts massfraction is the thermoplastic styrene butadiene rubber of 28%-35%, toluene that massfraction is 25%-35%, massfraction is 19%-39% YLENE and massfraction to be 8%-12% is processed; Its preparation process is to take by weighing toluene, YLENE, N-BUTYL ACETATE and thermoplastic styrene butadiene rubber 792 according to massfraction; Seal and leave standstill 180-450 minute; Carry out stirring at low speed with 200-350 commentaries on classics/min speed afterwards; Churning time 5-15 minute, mixing solutions presented homogeneous transparent liquid under the apparent state, seal preserve subsequent use;
Wherein to adopt massfraction be that the coumarone indene resin of 40%-60% and YLENE that massfraction is 60%-40% are processed to coumarone indene resin solution, and its preparation process is that the YLENE with weighing in proportion is loaded in the container, stirs with the speed of 600-900 commentaries on classics/min; In whipping process, load weighted coumarone indene resin is poured in the YLENE; Continue to stir 30-70 minute, and surveyed with Hegman grind gage, reaching below the 10 μ m with solution fineness wherein is standard; Stop to stir; Take out, apparent state is the light yellow or pale brown look liquid of no naked eyes visible particle, and it is subsequent use to seal preservation;
Prepare subsequent use component with above three kinds and take by weighing, at first thermoplastic styrene butadiene rubber is joined in the container, stir according to formula ratio; Stirring velocity is 200-300 commentaries on classics/min; In whipping process, in thermoplastic styrene butadiene rubber, add liquid modifying petroleum pitch solution and coumarone indene resin solution, stir after 3-7 minute, add load weighted flow agent and skimmer; With 1500-2000 commentaries on classics/min speed high-speed stirring 25-50 minute, make said bridge water-proof adhesive.
Use the construction technology of bridge water-proof adhesive, it is characterized in that, may further comprise the steps:
Step 1: processing base level---adopt sandblast hacking mode to handle; At first the imperfect attachment thing that has on the road surfaces is removed; Cleaning road surface dust, sand grains, foreign material; There is the smeary position can adopt solvent cleaning, cleaned the dry basal plane of available blower, promptly adopt sand shaker to carry out sandblasting behind the road cleaning;
Step 2: sticker construction---adopt artificial coating or spray dual mode and carry out; Consumption to the bridge water-proof adhesive is 0.4～0.7Kg/m2; This sticker needs construction at twice; The timed interval between implementing for the first time and for the second time at normal temperatures should be coated with back 12 hours at 4～8h for the second time, can carry out the construction of brea bed;
Said artificial coating process process is: before the construction, the bridge water-proof adhesive is poured in the container of suitable size, gentle agitation 3-5min is disposed its even roller coating on the basal plane in cement concrete or other with cylinder by operator.
Said spray coating constructing technique process is divided into artificial pistol spraying and pitch sprinkling car sprays; In area≤200 ㎡ scopes, adopt artificial pistol spraying; And when area＞200 ㎡ scopes, adopting pitch sprinkling car to spray, strict control quantity for spray is at 0.4～0.7Kg/m
2Scope.
This modification water-proof adhesive is that a kind of basal plane that is applicable to is that cement concrete, surface layer are the black flexible waterproof material of bituminous concrete.Its not only have good ductility, and concrete have stronger resistance to shear (anti-automobile braking force) arranged between stronger cohesive force and surface layer bituminous concrete and the cement concrete; But also have heatproof, cold-resistant (freeze proof) ability, and excellent antifatigue, aging-resistant ability.
