Abstract
The invention relates to a blending type room-temperature asphalt liquefier, which comprises the following components by weight percent: 5-12 percent of liquid modifier, 3-9 percent of cation surfactant, 2-5 percent of stabilizing agent and 20-30 percent of water. A preparation method of the blending type room-temperature asphalt liquefier comprises the following steps of: mixing water and the cation surfactant according to the proportion, sufficiently mixing by an emulsion machine to form soap lye, and heating to 55-70 DEG C, uniformly mixing the liquid modifier and the stabilizing agent according to the proportion to form a homogeneous body, and heating to 55-70 DEG C; quickly mixing the soap lye and the homogeneous body in a melt-mixing device, grinding to form even and stable jelly, and preserving in a sealing mode or an intermittence stirring mode. The liquefier can be simply mixed with asphalt to produce cold blending asphalt suitable for preparing cold blending mixing materials. The invention is used for paving an asphalt and concrete road surface.
Description
Technical field
Adjuvant used field when the present invention relates to the asphalt paving road surface relates in particular to a kind of blending type room-temperature asphalt liquefier.
Background technology
Highway pavement adopts pitch as the road surface gelling material in a large number.And pitch is at first wanted heating and melting as gelling material, and high class pavement is wanted modification processing, and simultaneously, gathering materials also to be heated to 200 ℃, carries out mix then, under keeping warm mode, through transporting, paving, roll, forms bituminous pavement.All processes need to consume a large amount of fuel, produce greenhouse gases.Simultaneously, engineering construction is subjected to weather effect serious, and operation cooperates strict, and material use efficiency is lower, and waste is serious.Serious environment pollution and workmen's is healthy.
Liquid SBS modified emulsified asphalt and preparation method that a kind of road construction that has been 200910027834.0 patent disclosure of the domestic patent No. and maintenance project are used: add liquid SBS modified dose, compound emulsifying agent and stablizer in the entry simultaneously, heat while stirring to 60-65 ℃, make liquid SBS modified dose with the mixed aqueous solution of compound emulsifying agent and by aqueous solution pump delivery; Heat matrix pitch to 135-140 ℃ and carry by bitumenpump; Water-soluble liquid pump and bitumenpump are carried to colloidal mill simultaneously, and the cutting and grinding of process colloidal mill gets final product.The present invention is according to different pitch, by liquid SBS modified dose of the composite compound emulsifying agent that adapts and rational Match, improved the every performance of bituminous; Asphalt modification and asphalt emulsification are finished synchronously, simplified technological process.Its weak point is that prepared SBS modified emulsifying asphalt can only be used for spraying as sticking layer oil or seal oil, and can not be used for the system of mixing of bituminous concrete.
Whole process need not outside the heating when needing a kind of and building stones mix badly, and can simplify construction process, prolong the construction time limit, improve construction environment, the product that strengthens construction quality occurs.
Summary of the invention
The object of the present invention is to provide a kind of blending type room-temperature asphalt liquefier, solve the problem that room-temperature asphalt production needs complicated technology, complicated prescription, complex operations, make room-temperature asphalt production at normal temperatures become simple and easy to do by modification, and be easy to scale operation.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of blending type room-temperature asphalt liquefier is characterized in that: the weight percent of its each component is:
Liquid modifying agent 15-35%
Cats product 10-20%
Stablizer 3-6%
Water 40-60%
Wherein, described liquid modifying agent is a liquid state, and its solid content is 35-50%; Described cats product is selected from one or more of tetradecylamine, hexadecylamine, octadecylamine, coconut oils amine, oleic acid amine; Described stablizer is one or more in the sulphur class organic compound; Described water requires that calcium ions and magnesium ions content is no more than 100mg in the water, and pH value is 7.0～7.5.
A kind of method for preparing the described liquefying agent of claim 1 is characterized in that: comprise the steps:
1) presses formula rate water is mixed with cats product, fully stir through mulser and form the soap lye body;
2) liquid modifying agent and stablizer agent mixing are formed liquid;
3) after saponification liquor and the step 2 that step 1) is formed) liquid that forms is heated to 55-70 ℃ respectively, in the mixing device the two is mixed, mixed material grinds by shredder and forms uniform and stable jelly, fully stirs, and is cooled to normal temperature storage promptly.
Tensio-active agent among the present invention is used for and will forms a stable uniform mixture between water, liquid modifying agent and the stablizer, makes the mutual glue of water base group and properties-correcting agent particulate join; Stablizer is used to improve the steady state of system, also is to provide the satisfactory stability effect for room-temperature asphalt simultaneously.
Beneficial effect of the present invention:
Adopt this room-temperature asphalt liquefier and pitch under lesser temps (100-130 ℃), to produce the modification room-temperature asphalt that adheres to specification.This room-temperature asphalt can be mixed system AC class, SMA class, OGFC class and ATB class, and its road surface thickness that paves can surpass more than the 2cm.Satisfy the requirement of the highway pavement of each grade, and can effectively improve construction environment, prolongation construction time limit, enhancing construction quality, reduce the construction energy consumption, raising material use efficiency, save energy.
Following examples further describe technique effect of the present invention; these embodiment only are used for illustrating content of the present invention; but do not limit the scope of the invention, those of ordinary skills drop within the protection domain of the present invention in the change under the prerequisite of inventive concept.
