Abstract
The invention discloses a kind of fast dewatering curing agent and its preparation method and application, formed by the anti-stripping agent of powder, breeze, polymer glue powder and cement allotment, curing agent is added after compound, normal temperature bituminous concrete fast dewatering, rapid curing, there is high plastoelastic surface layer and good weatherability, can solve traditional modified emulsifying asphalt concrete and dewater slowly, be not easy curing problem, greatly improve construction effect and social benefit.
Description
Technical field
The invention belongs to and newly repair normal temperature asphalt surface course and road maintenance repairing field, what be specifically related to is a kind of de-fastWater cure agent and its preparation method and application.
Background technology
The intensity of the general modified emulsifying asphalt compound in China market is formed with a process slowly at present, at standTool plasticity, mobility when spreading, rolling, can be extruded into irregular place in the groove of hole. Water under the effect of driving and airDivide and only rely on volatilization, pitch is retrogradation progressively, and the distribution between normal temperature asphalt particle is tightr, and porosity reduces, ore depositExpect mutual to cohere more firmly, and then the density of compound increases. Several days time of this process need, after this intensity also can be progressivelyIncrease, through after a period of time, its distortion and intensity can progressively be stablized, and reach the code requirement of modified emulsifying asphalt compound.And the intensity of normal temperature asphalt is made up of two parts: the one, because cohesiveness and the adhesion of modified pitch self are high, fromAnd the cohesive force of the compound forming with mineral aggregate interaction and adhesive force form. They make to be difficult between mineral aggregate particleSeparate, form entirety, also make compound and original surface will have compared with high adhesion strength and be difficult for peeling off, passing. The 2nd, compound warpRoll rear rapid curing, the internal friction of the compound forming due to the intergranular embedded squeezing keying action of mineral aggregate. Normal temperature pitchThis two parts power of compound just forms its early strength, and is enough to resist the effect of vehicular load.
Summary of the invention
The object of the invention is to overcome the above problem that prior art exists, provide a kind of fast dewatering curing agent andPreparation method and application, solve traditional modified emulsifying asphalt concrete and dewater slowly, are not easy problem of solidification.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of fast dewatering curing agent, comprises the material of following quality percentage composition:
The anti-stripping agent of powder 10%-15%
Breeze 10%-20%
Polymer glue powder 20%-30%
Sulphate aluminium cement 50%-70%
The anti-stripping agent of described powder belongs to non-amine organic compound; Described breeze is in bentonite clay or kaolin or wollastoniteOne or more combination; Described polymer glue powder is the acrylate of cation self-crosslinking modification.
A preparation method for fast dewatering curing agent, comprises the following steps:
Anti-powder stripping agent, breeze, polymer glue powder and aluminum sulfate salt cement are mixed at normal temperatures, in agitated kettle, stir3～5 minutes, agitator speed was 500～800 revs/min.
An application for fast dewatering curing agent, comprises the following steps:
Step 1) is put into basalt aggregate, fast dewatering curing agent in agitated kettle, stirs, and fast dewatering curing agentAccount for the 1.5-5.5% of basalt aggregate;
Step 2) water is added to agitated kettle;
Normal temperature mix pitch is added agitated kettle by step 3), forms compound;
Step 4) is placed on annular die trial on felt, and after compound is mixed thoroughly, pour into immediately in die trial and strike off, and compacting;
Step 5) timing, annular die trial reaches after initial set, by the test specimen demoulding;
Step 6) detects performance.
The invention has the beneficial effects as follows:
Curing agent has potent dehydration property and rapid curing ability, adds in right amount normal temperature asphalt as additiveIn, can reach quick absorption moisture, again can with water generation chemical reaction, form microfibre toughness reinforcing crystallization hydrated product, riseTo dehydration.
The curing agent reaction water yield is large, and water absorption is large, can with normal temperature pitch in a part of water meet hydration reaction occur, verySolve well normal temperature bituminous concrete fast dewatering, rapid curing, and then met in road asphalt concrete construction specification eachPerformance indications, make normal temperature mix bituminous liquids be basic slurry seal, micro-table place, crushed stone sealing, asphalt concrete pavement,Cold regeneration concrete, swag cold-repairing material etc. have powerful solidify, the advantage of fast dewatering. Road surface after moulding not only has high stickyKnot, high shear strength and Marshall stability, and there is good water resistance.
The normal temperature pitch solid content of selecting is more than 60%, and bin stability is greater than 12 months, and good stability has wellResistance to height, resistance to low temperature.
