Description
Technical field
The invention belongs to pavement construction material technical field, be specifically related to the embedding agent in the crack, seam embedding repairing etc. for bituminous pavement, cement concrete pavement.
Background technology
Along with expanding economy, resource shortage becomes increasingly conspicuous, the regeneration of waste and scrap, again use very important.In various plastics, polystyrene (PS) and expansible polystyrene (FPS) widespread use, in recent years, the whole world annual consumption polystyrene more than 1,000 ten thousand tons, and in ascendant trend year by year.Be even if that this kind of waste and old product are not degraded under field conditions (factors) for 200 years alarming, present polystyrene can have an impact to the living environment of several generations and even ten several generations, has caused serious " white pollution ", has caused ecotope to go from bad to worse.To this, be devoted to the research of its substitute all over the world, due to substitute, to there is cost high, and performance index do not reach the problems such as requirement and are difficult to extensively be suitable for.How reasonably to be recycled by waste and old polystyrol, be the focus that scientific worker pays close attention to always.
The factors such as be 400.82 ten thousand highways by highway in China in 2010 total kilometrage that is open to traffic, wherein motorway mileage is 7.41 ten thousand highways, the weather condition that overload and heavy duty, China are severe make road pavement performance worsen further.Compare external, the preventive maintenance of China's road and normal maintenance task more seriously, more urgently, propose higher technical requirements to maintenance new technology and New Maintenance Material simultaneously.Preventive maintenance maintenance emphasis is the timely embedding on road surface, stops water permeation roadbed on road surface, causes whole pavement structure to destroy, bring huge property damage to country.The Embedding Material of current bituminous pavement mainly contains: heated bitumen, emulsified bitumen, silicone, urethane etc.Adopt ordinary hot pitch embedding time, ordinary hot pitch in the case of a high temperature, the low phenomenon easily occurring bellding and taken away by vehicle of softening temperature, during low temperature, pitch can become fragile again, easily comes off; And adopt modification heated bitumen considerably less because the viscosity large trickling penetrating quality difference of modifying asphalt pours into the pitch of pavement crack, so very easily ftracture when pavement crack low temperature is expanded, repairing is short for work-ing life.Admixture solvent, the low-temperature fluidity penetrating quality of pitch is improved, but high-temperature stability elastic recovery properties reduces in eu-bitumen (emulsification), easily overflows to be taken away road pavement by vehicle and pollute when summer high temperature, Easy open during winter low temperature.Silicone embedding agent advantage is: the storage time is long, mechanical strength is moderate; Shortcoming is: set time is long, have obvious irritating smell, poor permeability poor to the adhesive property of bituminous concrete and expensive, is not suitable with the extensive use of highway maintenance.Encapsulating polyurethane agent has high thixotropic, and facade and top construction are not trickled, had high tensile strength, excellent elasticity, good weatherability, the advantages such as oil resistance is excellent, resistance to biological aging, moderate.But it can not be heat-resisting for a long time, single-component developing agent storage stability packed and ectocine larger, usual solidification is comparatively slow, may produce bubble and crackle under hot environment, polyurethane sealant water tolerance is also poor simultaneously, particularly alkaline-resisting water-based is not good enough, and this also affects the use of polyurethane sealant in maintenance of surface.Therefore there is hypertonicity, good high-temperature stability, low-temperature cracking-resistance, good elasticity are recovered, the research and production of cheap embedding agent also becomes increasingly conspicuous.China Patent No. (CN200410010907.2) high-performance pavement of road gap-grouting material and production technique;

Carry out road surface embedding to execute man-hour requirement to heat front viscosity to embedding agent large, be unfavorable for that rapid construction is repaired; When rubber agent powder volume is too much, low-temperature cracking-resistance is poor.China Patent No. (CN201310132488.9) a kind of joggle beam structure embedding agent and preparation and application thereof: be a kind of high-performance bicomponent epoxy resin agent stick, be made up of epoxy resin, reactive thinner, amine curing agent, toughner, promotor and high performance adjuvant.Wherein, by weight percentage: epoxy resin 50 ~ 70%; Reactive thinner 0 ~ 30%; Amine curing agent 15 ~ 50%; Toughner 0 ~ 20%; Promotor 0 ~ 5%; Coupling agent 0 ~ 5%; High performance adjuvant 0 ~ 5%.Shortcoming of this invention is: thinner and the amine curing agent proportion of employing are higher, and noxious gas emission is comparatively large, large to the physical impairment of producers and site operation personnel, and formula adopts the solidification of epoxy resin difficulty and expensive simultaneously.The research and the patent that waste and old polystyrol are applied to road surface Embedding Material are almost blank.

Advantageous Effects of the present invention embodies in the following areas:
1. the selection of filling a prescription and the mechanism of action:
1). surface active agent emulsions is the dispersion of polymer particles in water; oil-water interfacial tension can be reduced; oil dispersion is convenient to by high-speed stirring; and protective layer can be formed on drop surface; prevent cohesion; system is tended towards stability, and therefore its character and consumption have direct relation to the stability of speed of response, dispersion system and the performance of product.The surfactant that the present invention adopts, had both utilized the mechanical stability of anion surfactant emulsion, had utilized again non-tonic surface active agent emulsions secondary emulsification chemical stability.The compound surfactant that the present invention adopts has good emulsification, wetting, dispersion, antistatic, anti-performance of hard water;
2). the selection of the massfraction of tensio-active agent.Surfactant total mass number is larger, the agent bundle of formation the more, can stable surface-area also larger, emulsion system is more stable; Surfactant total mass number is fewer, and agent grain number is fewer, and agent plastochondria is long-pending also larger, and emulsion is unstable.The breakdown of emulsion time of the embedding agent of the comprehensive stability of emulsion of the present invention, preparation, the viscosity of embedding agent, by the massfraction of outdoor test determination tensio-active agent;
3). softening agent normally high boiling point, low volatilization, to heat and all very stable organic compound of chemical reagent, certain consistency should be had with polymkeric substance.Softening agent add the mutual attractive force that can weaken between macromolecular chain, macromole spacing is increased, and the motion ratio of molecular chain is easier to, thus reduces the second-order transition temperature of polymkeric substance, makes it show elastomeric state at low temperatures.Through the polymkeric substance of plasticising, its fragility, hardness reduce; And winter hardiness, snappiness, resistance to impact shock, elongation improve.The softening agent that the present invention determines and polymerising ethylene have good consistency, and effectively can improve adhesive power, the ductility of embedding agent;
4). Fillers selection and the mechanism of action.Because not having hydrophilic radical in polystyrene molecule, water-intake rate is low, and thus it has good water resistance, but its poor heat resistance, add the cost that filler not only can reduce embedding agent, increase stability and the wear resistance of embedding agent;
5). properties-correcting agent is selected and the mechanism of action.Not containing active group in polystyrene molecular structure, belong to apolar substance, and the existence of phenyl ring can produce sterically hindered, reduce the kindliness of polystyrene polymeric chain, hinder the diffusion of molecule, make using polystyrene separately as filmogen poor adhesive force, rete is easy to come off.Therefore, modification must be carried out to it when preparing embedding agent, to strengthen coating adhesion.The modification of p-poly-phenyl ethene has been reacted by chemical graft, i.e. introducing polar functional group on the molecule of polystyrene, improves the polarity of polystyrene.In polystyrene molecular structure on benzyl position corresponding to phenyl ring
comparatively active, be vulnerable to the attack that decomposition of initiator institute produces living radical, dehydrogenation produces macromolecular radical, and this free radical causes copolymerization, thus on polystyrene molecular chain, form some side chains containing carboxyl, ester group isopolarity group.The properties-correcting agent selection that the present invention determines and consumption, considering on embedding agent cost basis, effectively carrying out minor matters by p-poly-phenyl ethene, improve its adhesive property and film forming properties.
