Abstract
The invention relates to the technical field of engineering construction, in particular to thermosetting emulsified epoxy resin modified emulsified asphalt. The invention is realized by the following technical scheme: alkylphenol polyoxyethylene is used for emulsifying two-component A epoxy resins to form epoxy resin water emulsion through hybrid synthesis; the prepared epoxy resin water emulsion is mixed in emulsified asphalt to prepare thermosetting epoxy resin modified emulsified asphalt after full mixing; the mixture of one or more of modified aliphatic amine, phenolic aldehyde amine, aromatic amine and the like and the water solution of the alkylphenol polyoxyethylene are used for preparing the epoxy resin curing agent; and the epoxy resin curing agent is mixed with thermosetting epoxy resin modified emulsified asphalt in proportion. The emulsified asphalt has the advantages of convenient construction, conventional construction process and simple tools under normal temperature. The epoxy resin curing agent carries out reactive crosslinking with the thermosetting epoxy resin modified emulsified asphalt, so the performance of the emulsified asphalt is thoroughly changed, that is, the common emulsified asphalt begins melting at 60 DEG C, but the emulsified asphalt of the invention is not molten at 160 DEG C.
Description
Technical field
The present invention relates to the engineering construction technical field, refer in particular to the thermoset emulsion epoxy resin modified emulsifying 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, just unlimited extension forward in people's underfooting.From the rugged and rough trail that people tread, just the sidewalk to pebbles shop, from the cement pavement of concrete depositing, the bituminous pavement that is widely adopted until today has 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 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, to burn down at pyritous, 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 cryogenic winter, 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 big.
In order to solve the bituminous pavement cast of must the scene heating, seriously polluted, the shortcoming that labor intensity of operating staff is big, people have invented emulsified bitumen, heavy-gravity pitch is carried out emulsification after, again its similar watering generally is sprayed on the road surface of desire asphalt.Though solve above-mentioned shortcoming, and improved efficiency greatly, 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, makes the popularization of this technology be subjected to constraint.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point of the prior art, and a kind of thermoset emulsion epoxy resin modified emulsifying asphalt is provided.
The present invention is achieved through the following technical solutions: synthetic with nonionic surface active agent alkylphenol polyethylene oxide emulsification double A type Resins, epoxy (diphenylol propane glycidyl ether) through mixing, form the Resins, epoxy water-in-oil emulsion; The Resins, epoxy water-in-oil emulsion that makes is mixed in the emulsified bitumen, then makes the thermosetting epoxy resin modified emulsifying asphalt behind the thorough mixing.Make epoxy curing agent with one or more mixed amines of modified fatty amine, phenolic aldehyde amine, aromatic amine, polyetheramine, aliphatic cyclic amine and the aqueous solution of alkylphenol polyethylene oxide, epoxy curing agent mixes use with the thermosetting epoxy resin modified emulsifying asphalt in proportion.
Application, the easy construction of thermoset emulsion epoxy resin modified emulsifying asphalt, construction technology, simple tools with routine under the normal temperature can both operations.Epoxy curing agent and thermosetting epoxy resin modified emulsifying asphalt carry out that reactivity is crosslinked, and performance thoroughly changes, and 60 ° of C begin to dissolve from general emulsified bitumen, change 160 ° of all thawless characteristics of C into.
Embodiment
