Abstract

This case is related to the modified warm-mixing agent of pitch, by parts by weight in terms of, including following components: 100 parts of water；10-15 parts of sldium lauryl sulfate；3-5 parts of sodium carboxymethylcellulose；5-8 parts of Sodium Polyacrylate；3-5 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 organic combination, the viscosity of asphalt is reduced, improves the peeling resistance of asphalt；The construction temperature for reducing asphalt, reduces fuel consumption.

Description

The modified warm-mixing agent of pitch
Technical field
The present invention relates to a kind of warm-mixing agents, and in particular to a kind of modified warm-mixing agent of pitch.
Background technique
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 reaches or approaches the pitch mixing power-saving technology of hot-mix asphalt mixture.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 20% or more energy saving, while asphalt storage temperature reduces, the mobility enhancing under lower temperature, it secondly can To reduce discharge amount.
Warm-mixing agent in the prior art mainly depends on traditional warm-mixing agent and is developed and improved, but these warm-mixing agents are right The modification amplitude of pitch is smaller, therefore, how to improve the performance indicators such as the low-temperature ductility, hot mastication point, needle penetration of pitch, at In order to which the following warm-mixing agent needs improved direction.
Summary of the invention
In view of the deficiencies of the prior art, the purpose of the present invention is to provide a kind of modified warm-mixing agents of pitch.
Technical solution of the present invention is summarized as follows:
A kind of modified warm-mixing agent of pitch, by parts by weight in terms of, including following components:
Preferably, the modified warm-mixing agent of the pitch, wherein further include the acetyl tributyl citrate three for having 2-3 parts by weight Butyl ester.
Preferably, the modified warm-mixing agent of the pitch, wherein further include the calcium chloride for having 2-3 parts by weight.
Preferably, the modified warm-mixing agent of the pitch, wherein further include the potassium chloride for having 2-3 parts by weight.
Preferably, the modified warm-mixing agent of the pitch, wherein further include the oleic acid for having 2-3 parts by weight.
Preferably, the modified warm-mixing agent of the pitch, wherein the number-average molecular weight of the Sodium Polyacrylate is 1000-3000g/mol。
Preferably, the modified warm-mixing agent of the pitch, wherein further include the cocamidopropyl propyl amide for having 2-3 parts by weight Glycine betaine.
The beneficial effects of the present invention are: this case is improved by the formula to existing warm-mixing agent, 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
The present invention will be further described in detail below with reference to the embodiments, to enable those skilled in the art referring to specification Text can be implemented accordingly.
This case provides the modified warm-mixing agent of pitch of an embodiment, by parts by weight in terms of, including following components:
It wherein, further preferably include the tributyl 2-acetylcitrate of 2-3 parts by weight.
It wherein, further preferably include the calcium chloride of 2-3 parts by weight.
It wherein, further preferably include the potassium chloride of 2-3 parts by weight.Potassium chloride for reducing asphalt viscosity.
It wherein, further preferably include the oleic acid of 2-3 parts by weight.
Wherein, the number-average molecular weight of Sodium Polyacrylate is preferably 1000-3000g/mol.
It wherein, further preferably include the Cocoamidopropyl betaine of 2-3 parts by weight.
The additive amount of the warm-mixing agent of this case is the 2-5wt% of matrix pitch.That is, the preparation process very simple of warm-mixing agent will Each component is sufficiently stirred after mixing with water, until being completely dissolved.
Table 1 lists the warm-mixing agent of different embodiment 1-6 and the performance indicator of asphalt:
Table 1
Table 2 lists the warm-mixing agent of different embodiment 7-12 and the performance indicator of asphalt:
Table 2
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited In specific details.
