Description
Technical field
The present invention relates to a kind of preparation method of epoxy radicals pavement patching material, belongs to patching material preparing technical field.
Background technology
The phenomenon that concrete occurs destruction in the civil engineerings such as discovered in recent years airport, road, bridge is on the increase, and causes
Economic loss directly or indirectly is huge.Its reason is except concrete durability when use environment condition becomes harsh and design
Bad outer, with construction management not enough, blindness pursuit progress, the factor such as even use inferior materials and turn out substandard goods also have much relations.Therefore, in order to the greatest extent
Pipe recovers the use function of these xoncrete structures and ensures safety in utilization, it is necessary in time they are repaired.
Existing more common material for road repair has accelerated cement, modified pitch, epoxy resin daub etc..Wherein, fast solidifying
Cement material inconvenience under conditions of the rainy day is constructed or can not be constructed, and also needs to the maintenance of a quiet time, it is impossible in time after construction
It is open to traffic；Modified pitch needs scene to boil or mix, not only pollutes environment and the engineering time is longer, additionally, also existing because of caking property
Under strong, hot conditionss, easily trickling does not make, color distinction the is big deficiency polluted by periphery road surface, repairs thin layer（Within 3cm）More
It is to carry out；Epoxy resin based patching material there is also the problem of curing time, and because of cement concrete and epoxy resin soil
Between differ in the state of temperature and stress, with the growth of use time, easily come off or produce new crack and crack；
And epoxy resin based patching material mostly be double-component or the above proportioning mixing of two kinds of components after constructed again, surplus after proportioning
Remaining material, it is impossible to reclaim and use, cause to waste.
Content of the invention
The technical problem to be solved：For epoxy resin based patching material common at present because of cement concrete
The state that there is temperature and stress between epoxy resin is differed, and with the growth of use time, is easily come off or is produced and be new
Crack and crack problem, the present invention with Stalactitum as raw material, through liquid nitrogen freezing, after ice splits efflorescence, by itself and urea liquid,
After calcium hydroxide mixing, heating under pressure environment makes hydrolysis of urea discharge carbon dioxide, generates carbonic acid with calcium hydroxide reaction
Calcium crystallisation adsorption on Stalactitum is obtained selfreparing filler, then carries out surface in the presence of microorganism through natural resin Resina persicae
Modification, last and epoxy resin slurry compounding are obtained epoxy radicals pavement patching material, utilize in patching material obtained in the present invention
Used as crystal seed, in the environment of having water and carbon dioxide, crystal seed constantly can grow Stalactitum after absorption Calcium Carbonate, to repairing be
The crack and crack of generation is filled up, and high mechanical strength, will not fall off phenomenon, has broad application prospects.
For solving above-mentioned technical problem, the technical solution used in the present invention is：
（1）Weigh 1～2kg Stalactitums and be put into 10～12h of immersion in methane-generating pit, tile after immersion cold with liquid nitrogen spraying on the ground
Freeze 3～5min, be immediately placed in after spray in jet mill after crushing 1～2h and cross 100 mesh standard sieves, obtain Stalactitum powder；
（2）200～300g Stalactitum powder is added in the urea liquid that 3～4L mass fractions are 20～30%, ultrasonic disperse
20～30min obtains suspension, then in suspension adds 0.4～0.6g calcium hydroxide, continues 10～15min of ultrasonic disperse and obtains instead
Answer liquid；
（3）Above-mentioned reactant liquor is moved in autoclave, is heated to 80～85 DEG C and reacting kettle inner pressure is improved to 2.5
～3.0MPa, starts agitator pressurize 2～4h of stirring reaction, and reactor pressure release to normal pressure, taking-up are reacted after terminating by question response
Thing is simultaneously centrifugally separating to obtain precipitate with 3000～4000r/min rotating speeds, obtains chipping filler after drying；
（4）Take that Radix Betae is peeled and stripping and slicing is squeezed the juice, obtain beet juice, be 1 in mass ratio:1:2, by above-mentioned chipping filler, beet juice
Be sequentially loaded in fermentation tank with Resina persicae, then the deionized water of 3～5 times of three's gross mass added in tank, will send out after mix homogeneously
Fermentation tank is placed on natural fermentation 12～14 days in the environment that temperature is 30～40 DEG C, relative air humidity is 70～80%；
（5）Above-mentioned fermented product is taken out, filtering residue is filtrated to get, deionized water is rinsed repeatedly 3～5 times and obtains modified repairing and fills out
Material, is counted by weight, weighs 10～15 parts of bisphenol A type epoxy resins, 3～5 parts of acetone and 8～10 parts of polyamide stirring mixing
Epoxy slurry is obtained after uniform；
（6）Count by weight, weigh 60～65 parts of above-mentioned modified chipping fillers, 8～12 parts of Pulvis Talci and 10～15 parts above-mentioned
Epoxy slurry is put in blender, to discharge after 60～80r/min rotating speeds stirring 20～30min of mixing, obtains final product epoxy radicals road surface
Patching material.
The application process of the present invention：First the pavement crack of required reparation is cleaned up, then ring prepared by the present invention
Epoxide pavement patching material is cast in pavement crack, through compacting, is struck off so as to flush with road surface, after which solidifies, is supported naturally
6～8h of shield.After testing, the repairing road surface comprcssive strength after hardening reaches more than 52MPa, rupture strength reach 9.5MPa with
On, using 8～10 years, do not produce new crack and crack.
Compared with additive method, Advantageous Effects are the present invention：
（1）Epoxy radicals pavement patching material prepared by the present invention is not affected by, is not produced using 8～10 years
New crack and crack；
（2）Epoxy radicals pavement patching material its intensity prepared by the present invention is higher, not easy to crack, comprcssive strength reach 52MPa with
On, rupture strength reaches more than 9.5MPa；
