Abstract
This case is related to the modified warm-mixing agent of pitch, with weight portion to count, including following components：100 parts of water；10 15 parts of sldium lauryl sulfate；35 parts of sodium carboxymethylcellulose；58 parts of Sodium Polyacrylate；35 parts of p-methyl benzenesulfonic acid sodium.This case is improved by the formula to existing warm-mixing agent, and multiple components are carried out into organic combination, reduces the viscosity of asphalt, improves the peeling resistance of asphalt；The construction temperature of asphalt is reduced, fuel consumption is reduced.
Description
Technical field
The present invention relates to a kind of warm-mixing agent, and in particular to a kind of pitch warm-mixing agent that is modified.
Background technology
Warm-mixed asphalt technology is that one kind mixes and stirs temperature between hot asphalt technology (150-180 DEG C) and cold-mix asphalt technology
Between (10-40 DEG C), performance reach or close to hot-mix asphalt mixture pitch mix power-saving technology.Warm-mixed asphalt technology and mark
Quasi- hot asphalt is compared, and temperature can reduce 20-30 DEG C.Warm-mixed asphalt can reduce bituminous mixture and construction temperature,
Can be with saving energy consumption more than 20%, while the reduction of asphalt storage temperature, the mobility enhancing under lower temperature secondly can
To reduce discharge capacity.
Warm-mixing agent of the prior art mainly depends on traditional warm-mixing agent and develops and improve, but these warm-mixing agents are right
The modified amplitude of pitch is smaller, therefore, the performance indications such as low-temperature ductility, hot mastication point, the needle penetration of pitch how are improved, into
In order to following warm-mixing agent needs improved direction.
The content of the invention
In place of in view of the shortcomings of the prior art, it is an object of the invention to provide a kind of pitch warm-mixing agent that is modified.
Technical scheme is summarized as follows：
With modified warm-mixing agent, it is with weight portion to count, including following components for a kind of pitch：
Preferably, the described pitch warm-mixing agent that is modified, wherein, also include the acetyl tributyl citrate three of 2-3 weight portions
Butyl ester.
Preferably, the described pitch warm-mixing agent that is modified, wherein, also include the calcium chloride of 2-3 weight portions.
Preferably, the described pitch warm-mixing agent that is modified, wherein, also include the potassium chloride of 2-3 weight portions.
Preferably, the described pitch warm-mixing agent that is modified, wherein, also include the oleic acid of 2-3 weight portions.
Preferably, the described pitch warm-mixing agent that is modified, wherein, the number-average molecular weight of the Sodium Polyacrylate is
1000-3000g/mol。
Preferably, the described pitch warm-mixing agent that is modified, wherein, also include the cocamidopropyl propyl amide of 2-3 weight portions
Glycine betaine.
The beneficial effects of the invention are as follows：This case is improved by the formula to existing warm-mixing agent, and multiple components are carried out
Organic combination, reduces the viscosity of asphalt, improves the peeling resistance of asphalt；Reduce asphalt
Construction temperature, reduce fuel consumption.
Specific embodiment
With reference to embodiment, the present invention is described in further detail, to make those skilled in the art with reference to specification
Word can be implemented according to this.
This case provides the pitch of an embodiment modified warm-mixing agent, and it is with weight portion to count, including following components：
Wherein, the tributyl 2-acetylcitrate of 2-3 weight portions is further preferably included.
Wherein, the calcium chloride of 2-3 weight portions is further preferably included.
Wherein, the potassium chloride of 2-3 weight portions is further preferably included.Potassium chloride is used to reduce the viscosity of asphalt.
Wherein, the oleic acid of 2-3 weight portions is further preferably included.
Wherein, the number-average molecular weight of Sodium Polyacrylate is preferably 1000-3000g/mol.
Wherein, the Cocoamidopropyl betaine of 2-3 weight portions is further preferably included.
The addition of the warm-mixing agent of this case is the 2-5wt% of matrix pitch.The preparation technology very simple of warm-mixing agent, will
Each component is sufficiently stirred for after mixing with water, until being completely dissolved.
Table 1 lists the warm-mixing agent of different embodiment 1-6 and the performance indications of asphalt：
Table 1
Table 2 lists the warm-mixing agent of different embodiment 7-12 and the performance indications of asphalt：
Table 2
Although embodiment of the present invention is disclosed as above, it is not restricted to listed in specification and implementation method
With, it can be applied to various suitable the field of the invention completely, for those skilled in the art, can be easily
Other modification is realized, therefore under the universal limited without departing substantially from claim and equivalency range, the present invention is not limited
In specific details.
