Abstract
The invention discloses a preparation method of a special emulsifier for cationic cold-mix asphalt. The method comprises the following steps: adding the raw materials lignin, vinylamine, formaldehyde and water according to the mass ratio at different times, and carrying out sectional reactions at different temperatures to obtain the special emulsifier for cationic cold-mix asphalt. The cheap papermaking waste liquid lignin is used as the basic material to prepare the special emulsifier for cationic cold-mix asphalt; the emulsifier has excellent emulsifying property for different types of asphalt; and the prepared emulsified asphalt has the characteristics of stable quality, favorable wrapping property, high forming speed and the like, and has favorable field application effects.
Description
Technical field
The present invention relates to a kind of preparation method of positively charged ion cold-mix asphalt emulsifier special, belong to asphalt emulsifier technology.
Background technology
Asphalt emulsifier is made up of the polar group of hydrophilic (or hating oil) and the nonpolar group (being generally hydrocarbon chain) of oleophylic (or hydrophobic).
Cold-mix asphalt compound is with the asphalt of emulsified bitumen (modified emulsifying asphalt) with various types of grating mineral aggregate mixing, is compared to hot-mix asphalt mixture and has normal temperature mix, normal temperature construction; Be easy to pave, roll; Energy-conserving and environment-protective; , not easily there is the advantages such as temperature shrinkage fracture in shaping rear stable performance; Be generally used for the oil mat of three grades of (below) highways, the finish coat of Class II highway, and the cutting optimal of asphalt highway at different levels, context layer or regulating course.
Domestic and international emulsifying agent at present, mainly following several structure: quaternary, acid amide type, imidazoline type and alkyl diamine series etc.The emulsifying agent of invention belongs to modified lignin resin amine emulsifying agent, xylogen amine type asphalt emulsifier mainly by Mannich Reactive Synthesis, the reaction as xylogen and tetraethylene pentamine and formaldehyde:
This emulsifier ability is strong, and emulsion state is stablized, and the cold mixing made has with (modification) emulsified bitumen wraps up in good, the shaping feature such as soon of attached property, has good effect of field application.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of positively charged ion cold-mix asphalt emulsifier special.The method process is simple, and obtained cation asphalt emulgent, for different pitch, all has good emulsifying effectiveness.
The present invention is realized by the following technical programs, a kind of preparation method of positively charged ion cold-mix asphalt emulsifier special, it is characterized in that comprising following process: by xylogen and ethene amine and formaldehyde and and water, mass ratio is 1:(0.32 ~ 0.73): 0.51:(0.76 ~ 1.76), first, water is added in reactor, be warming up to 40 DEG C, start to add xylogen in reactor, stir after 1 hour, continue to be warming up to 80 DEG C, polyamines is added in reactor, stir lower reaction after 1 hour, start to drip formaldehyde solution, after dropwising, 80 DEG C are reacted 5 hours, after insulation reaction, be cooled to 60 DEG C of dischargings, obtain positively charged ion cold-mix asphalt emulsifier special.
The invention has the advantages that, use the papermaking wastewater xylogen from cheapness to be basic raw material, in strict accordance with the inner link of synthesis, properity and application, synthesize positively charged ion cold-mix asphalt emulsifier special.This emulsifying agent all has excellent emulsifying property for the pitch of different varieties, emulsified bitumen steady quality obtained in this approach, wraps up in good, the shaping feature such as soon of attached property, thus ensures the quality of building the road and repairing the roads.
