Abstract
The invention relates to the technical field of engineering construction, in particular to thermosetting emulsified flexible epoxy resin modified emulsified asphalt. The emulsified asphalt is characterized in that alkylphenol polyoxyethylene is used for emulsifying two-component A epoxy resins to prepare epoxy resin water emulsion; the alkylphenol polyoxyethylene is used for emulsifying nonyl phenol-terminated polyurethane resins to prepare the water-emulsified epoxy resin toughening agent; the epoxy resin water emulsion is mixed with the water-emulsified epoxy resin toughening agent to prepare the emulsified flexible epoxy resin; mixture of one or more of modified aliphatic amine, phenolic aldehyde amine and the like and the alkylphenol polyoxyethylene are used for preparing the water-emulsified epoxy resin curing agent; and the emulsified flexible epoxy resin and the water-emulsified epoxy resin curing agent are mixed with emulsified asphalt. The emulsified asphalt has the advantages of convenient construction, conventional construction process and simple tools under normal temperature. The water-emulsified epoxy resin curing agent carries out reactive crosslinking with the emulsified flexible epoxy resin modified asphalt, so the performance of the emulsified asphalt is thoroughly changed, that is, the common emulsified asphalt begins melting at 60 DEG C and is hardened and undergoes frost crack at minus 20 DEG C, but the emulsified asphalt of the invention is not molten at 160 DEG C and is free from brittle rupture at minus 25 DEG C and maintains flexibility for a long time under normal temperature.
Description
Technical field
The present invention relates to the engineering construction technical field, refer in particular to the thermosetting emulsified flexible epoxy resin modified emulsified asphalt of stress absorbing layer that a kind of waterproof that is widely used in highway, bridge, building foundation, bonding, the cementation of fissures, bituminous concrete cast be added with layer etc.
Background technology
Since the mankind's civilization comes into existence, road, the just unlimited forward extension in people's underfooting.From the rugged and rough trail that people tread, spread just sidewalk to pebbles, from the cement pavement of concrete depositing, until the bituminous pavement that is widely adopted today, proved the development history of human civilization from a side.
We know, the bituminous pavement that is widely adopted now have wear resistance good, do not play the advantages such as dirt, motor-driven vehicle going braking is good, yet it also has, and melting point is low, the shortcoming of poor performance at low temperatures.That is be in hot summer, under the burning of high temperature, the heat absorption of the road surface of black is softening, and under the rolling of motor vehicle, soft road surface is easy to form pit and convex closure; In the winter of low temperature, the shortcoming of poor performance at low temperatures makes it be easy to be full of cracks, the process of wheel, and be full of cracks place is then damaged, causes the damage on road surface.The shortcoming that other has a maximum is the bituminous pavement cast of must the scene heating, and seriously polluted, labor intensity of operating staff is large.
In order to solve the bituminous pavement cast of must the scene heating, seriously polluted, the shortcoming that labor intensity of operating staff is large, people have invented emulsified bitumen, the pitch of thickness is carried out emulsification after, again its similar watering generally is sprayed on the road surface of wish asphalt.Although solve above-mentioned shortcoming, and improved greatly efficiency, reduced labour cost, the consumption of asphalt amount on equal road surface is reduced.But, but because after pitch carried out emulsification, its melting point was lower, so that the popularization of this technology has been subject to constraint.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point of the prior art, and a kind of thermosetting emulsified flexible epoxy resin modified emulsified asphalt is provided.
The present invention is achieved through the following technical solutions: with nonionic surface active agent alkylphenol polyethylene oxide emulsification double A type Resins, epoxy (diphenylol propane glycidyl ether); With nonionic surface active agent alkylphenol polyethylene oxide the polyurethane resin of nonyl phenol end-blocking is carried out emulsification, make the emulsifying water epoxy resin toughener; Both are hybridly prepared into the emulsification flexible-epoxy mutually; One or more mixed amines and nonionic surface active agent alkylphenol polyethylene oxide with modified fatty amine, phenolic aldehyde amine, aromatic amine, polyetheramine, aliphatic cyclic amine are made emulsifying water type epoxy curing agent, and the two mixes use with emulsified bitumen.
The application of thermosetting emulsified flexible epoxy resin modified emulsified asphalt, easy construction, under the normal temperature with the construction technology of routine, simple instrument can both operation.It is crosslinked that water oil-in-water type epoxy curing agent and emulsification flexible-epoxy modifying asphalt carry out reactivity, performance thoroughly changes, begin to dissolve from 60 ℃ of general emulsified bitumens, the performance of-20 ℃ of sclerosis bursting by freezing changes into and keeps pliable and tough characteristic for a long time under 160 ℃ of all insoluble ,-25 ℃ of not embrittlement, the normal temperature.
