Background technique
In cement concrete bridge deck or tunnel pavement bituminous concrete, erosion of the moisture to concrete in order to prevent is needed
Water-proof tack coat is set in concrete surface.For common asphaltic base water-proof bond material since intensity is low, cementitiousness is insufficient,
Bituminous concrete is easy to produce delamination, and then the diseases such as delamination, pit slot occurs, reduces the service performance of road and uses the longevity
Life.The emulsified asphalt modified with water-epoxy resin water-proof bond material of normal temperature cure is in a liquid state before uncured, is easy to be constructed
Wheel of vehicle is taken away, if control is improper cured before bituminous concrete of not constructing, water-proof tack coat is to bituminous concrete
Cementitiousness is extremely low, and expected effect is not achieved.
Summary of the invention
The present invention uses the higher melting-point aqueous epoxy resins of evaporated residue and aqueous epoxy curing agent, can increase water
The Interface enhancer of cement concrete surface strength and it can be improved organic material to the coupling agent of inorganic interface adhesion to cream
Change pitch to be modified, obtains the waterborne epoxy modified emulsified asphalt composite water-proof binding material of function admirable.
To achieve the above object, the technical solution of the present invention is as follows:
A kind of emulsified asphalt modified with water-epoxy resin composite water-proof binding material, includes the following parts by weight:
The aqueous epoxy resins solid content is 30~60%, and the fusing point of its evaporated residue is greater than 50 DEG C.
The aqueous epoxy curing agent is the water-solubility modifying aromatic amine or modified anhydride of solid content 30~50%, and
The fusing point of its evaporated residue is greater than 50 DEG C.
The emulsified asphalt is the anionic emulsified bitumen of solid content 30~70%.
The styrene-butadiene latex is the anionic latex of solid content 25~50%.
The defoaming agent is silicone emulsion, dimethyl silicone polymer, high-carbon alcohol fatty acid ester, polyoxyethylene ether, polyoxy
One of propylene ether.
The coupling agent is one of silane coupling agent, titanate coupling agent.
The Interface enhancer is one of the lithium metasilicate of solid content 20~50%, sodium metasilicate.
The emulsified asphalt modified with water-epoxy resin composite water-proof binding material, preparation method are by water-base epoxy
Resin, emulsified asphalt, styrene-butadiene latex, defoaming agent, coupling agent, Interface enhancer, which are uniformly mixed, forms component A, water-base epoxy solidification
As B component, two component of A, B is uniformly mixed by when application for agent.
It is an advantage of the invention that the aqueous epoxy resins and aqueous epoxy curing agent that use are after moisture evaporation drying
Solid-state can resist the rolling without being taken away by wheel of Construction traffic, and it does not solidify at normal temperature or curing rate is slow, to
Pave asphalt when melted by heat and complete to solidify, bituminous concrete can be bonded on concrete surface securely.Boundary
Face reinforcing agent lithium metasilicate can enhance cement concrete surface, and styrene-butadiene latex film formation compactness and flexibility are good, and coupling agent makes
Organic material is high to inorganic interface binding intensity, and therefore, emulsified asphalt modified with water-epoxy resin provided by the present invention is compound
Water-proof bond material has both the performance of waterproof and bonding.
