Description
Technical field
The invention belongs to field of waterproof materials, and in particular to a kind of cement concrete bridge deck waterproof material and its preparation side
Method.
Background technology
Currently, the highway in China especially expressway construction have developed rapidly.In constructing road, miscellaneous bridge
Occupy considerable part ratio in the total kilometrage of highway, for a long time, since the waterproof to cement concrete bridge deck is paid little attention to,
It directly or carries out after simply improveing, roof waterpoof material is applied to bridge deck water-proof, often occurs such as grade separation in Practical Project
The problems such as bridge water permeating of bridge floor, pave-load layer peel off, floorings are broken.Bridge is caused to occur steel bar corrosion etc. due to the infringement of water resistance to
Long sex chromosome mosaicism causes huge security risk and economic loss.Studies have shown that the infiltration of water be cause these destroy most directly
One of with most important reason.The infiltration and delay of water, at temperature and load comprehensive function, not only cause face layer it is loose,
It peels off and pit slot is destroyed, moreover, water leaking-in can cause base's softening, strength reduction, and then induce the more serious destruction of face layer.
In order to protect floorings, prevents track or crawler belt from directly wearing away bridge floor, and the load so as to disperseing wheel, usually use cement
Concrete and asphalt concrete pavement bridge floor, and be to meet that good waterproof performance, stability are good, crack resistance is good, durability is good and layer
Between the good requirement of caking property, generally will waterproof layer be set in deck paving interlayer.
In recent years, waterproof material industry development is at full speed, many different types of waterproof materials occurs.From the point of view of performance,
Common waterproof material includes mainly flexible and rigid two major classes waterproof material.Conventional waterproof material is in the majority with flexible water, generally
Waterproof layer is formed to reach waterproof purpose in matrix surface by using flexible waterproof material, it is durable due to this kind of material
Property, compatibility are poor, and cost is higher, cannot meet the requirement in some fields.Rigidity water-proofing material is with cement, sand, Shi Wei
The cement mortar with certain impermeability is made in raw material, although constructing operation is simple, low cost, easily repairing, toughness
Difference, ultimate tensile strength are low, crack with globality, are suitable for small-scale waterproof, it is difficult to be competent at extensive waterproof.
Invention content
The technical problems to be solved by the invention：For current waterproof material in flexible waterproof material durability, compatible
Property is poor, and cost is higher, and rigidity water-proofing material poor toughness, ultimate tensile strength are low, crack with globality, are suitable for
Small-scale waterproof, it is difficult to be competent at extensive waterproof, provide a kind of cement concrete bridge deck waterproof material and preparation method thereof.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
It counts in parts by weight, including following components：80~90 parts of cement, 20~30 parts of mineral slurries, 60~80 parts of silicon third

(3) in mass ratio 1:10, mixed-powder is added to the water, is heated to 100~105 DEG C, 30~40min of insulated and stirred
After be cooled to 50~60 DEG C, acrylic acid, dimethyl diallyl ammonium chloride and ammonium persulfate is added, stir after 10~20min plus
Enter N, N '-methylene-bisacrylamides are added glycerine after reacting 3~5h, continue to be stirred to react 40~50min, go out after reaction
Material, you can obtain mineral slurries.
The fiber is one or more of bamboo fibre, castor-oil plant fiber, carbon fiber, abaca fibre or acetate fiber.
The dispersant is one kind in poly-epoxy succinic acid, neopelex or fatty alcohol-ether sodium sulfate.
The initiator is appointing in ammonium persulfate, potassium peroxydisulfate, potassium peroxydisulfate-potassium bisulfite and potassium thiosulfate
Meaning is a kind of.
The tackifying resin is any in coumarone indene resin, rosin resin, terpene resin.
A kind of preparation method of cement concrete bridge deck waterproof material, it is characterised in that：Specifically preparation process is：
(1) cement and mineral slurries are mixed, fiber is added after stirring, is stirred to obtain component A；
(2) silicone acrylic emulsion, tackifying resin are mixed, stirs evenly, obtains component B；
(3) component A and component B are mixed, initiator is added after mixing, dispersant is added after stirring 20~30min and disappeared
Infusion continues to discharge after being uniformly mixed, you can obtain cement concrete bridge deck waterproof material.
Compared with other methods, advantageous effects are the present invention：
(1) mineral slurries are added in waterproof material prepared by the present invention, mineral slurries are by acrylic acid and dimethyl
Diallyl ammonium chloride is reacted under the action of initiator, and obtained reaction solution is covered in the mines such as waste ceramic, dolomite
Object surface, obtained mineral slurries add in waterproof material, active material can be made to penetrate into inside cement matrix, plugging hole
Good waterproof effect is played in gap, crack；
(2) cement is added in the waterproof material that is prepared of the present invention, the waterproof material using when add water use, make water
A large amount of hydrated calcium silicates and calcium carbonate crystal body can be generated under the conditions of mud is existing for water, and there is the energy for repairing the crack of itself
Power, and cement mortar energy depth crystallization, freeze proof antiacid alkali ability are good；
It (3), can be in the work of initiator after the material mixings such as the present invention is prepared mineral slurries and cement, silicone acrylic emulsion
Under, mineral slurries and silicone acrylic emulsion further carry out cross-linking reaction, the waterproof material obtained after reaction, and the present invention prevents flexibility
Water material and rigidity water-proofing material are combined, and not only reduce that flexible waterproof material is of high cost, the problem of durability difference, and are solved
It has determined rigidity water-proofing material poor toughness, tensile strength is low, problem easy to crack；
(4) the waterproof material constructing operation that the present invention is prepared is safe and simple, and speed of application is fast, and film formation time is short, right
Roadway Construction is of less demanding, can rapid construction, apply in large-scale waterproofing work.
