Description
Technical field
The present invention relates to a kind of preparation methods of high stable type lignin asphalt emulsifier, belong to asphalt emulsifier technology neck
Domain.
Background technique
Cationic lignin amine be it is water-soluble, to formed cationic asphalt lotion it is largely effective.It has been used to CSS grades
（Cation is split slowly）Application of emulsified asphalt, such as palliative, pitch adhesion coating, sealant and surface treatment etc..Led to by lignin
The lignin amine and lignin quaternary for crossing Mannich reaction or the preparation of O- alkylated reaction obtain in cationic emulsified bitumen
It must be widely applied.It belongs to slow breaking cationic emulsifier, and cheap, the emulsified asphalt energy and fine aggregate prepared with it
It mixes and stirs to obtain uniform thin pulp, therefore, is particularly suitable for applying in slurry seal.
Certainly, from the point of view of the application of current lignin amine asphalt emulsifier, there is also some shortcomingss, such as：Emulsifying power
Power is poor, and the storage stability of emulsified asphalt is also undesirable, and when being used for slurry seal, de-emulsification speed is too slow etc..Lignin sulfonic acid
Salt is the main component in spentsulfiteliquor, usually there is the lignosulfonates of sodium, calcium and ammonium salt base, belongs to anion cream
Agent is used to prepare anionic emulsified bitumen.It can also add it in certain cation emulsions, to slow down cation emulsion
De-emulsification speed obtains covering uniform cationic emulsified bitumen mixture.But due to anionic emulsified bitumen and acidic aggregate
Adhesiveness it is bad, anionic emulsified bitumen is replaced cationic emulsified bitumen at present, and therefore, lignosulfonates are in cream
The application changed in pitch is restricted.
Summary of the invention
The technical problems to be solved by the invention：It is not high for existing lignin asphalt emulsifier material settling out performance, with
The bad problem of the adhesiveness of acidic aggregate provides a kind of preparation method of high stable type lignin asphalt emulsifier.
In order to solve the above technical problems, the technical solution adopted by the present invention is that：
（1）Black garlic and vacuum freeze drying are taken, grinds and sieves with 100 mesh sieve, collects sieving powder and in mass ratio 1:10, incited somebody to action
Sieve powder is added in ethanol solution, is stirred simultaneously ultrasound assisted extraction, is stood cooling after insulation reaction, obtain extracting solution；
（2）By extracting solution rotary evaporation, obtain extraction concentrate, according to parts by weight, respectively weigh 45~50 parts of lignin, 10~
15 parts of 1% sulfuric acid of mass fraction and 85~90 portions of extraction concentrates are placed in a beaker, and are stirred and oil bath heating, standing cool down
To room temperature, filter cake is filtered and collected, washs to obtain modified lignin resin；
（3）According to parts by weight, 45~50 parts of 5% trimethylamine solutions of mass fraction, 10~15 parts of mass fractions 1% are weighed respectively
Hydrochloric acid and 45~50 parts of epoxychloropropane are placed in three-necked flask, are stirred and are placed in 3~5h of insulation reaction at 0~10 DEG C,
To after the reaction was completed, obtain reaction solution and be 8.0 to ammonia is led in reaction solution to reaction solution pH, after standing 6~8h, collect modified
Matrix liquid；
（4）According to parts by weight, 45~50 parts of modified matrix liquid, 10~15 parts of modified lignin resins, 1~2 part of sulfuric acid are weighed respectively
Dimethyl ester and 1~2 part of dibutyl tin dilaurate are placed in three-necked flask, are stirred simultaneously oil bath heating, are filtered and collect filter
Liquid, standing are cooled to room temperature, and can be prepared into the high stable type lignin asphalt emulsifier.
Step（1）The Extracting temperature is 75~80 DEG C.
Step（2）The rotating evaporation temperature is 40~45 DEG C.
Step（2）The rotary evaporation is rotary evaporation to the 1/5 of extracting liquid volume.
Step（4）The oil bath heating temperature is 120~130 DEG C.
The present invention is compared with other methods, and advantageous effects are：
Technical solution of the present invention to black garlic by extracting and collecting the phenolic substances pair of the antioxygenic property contained in black garlic
Lignin material is modified processing, since lignin is present in plant fiber, has complex space reticular structure, wooden
In the structural unit of element, pass through the position α on the carbonyl on the ortho para and side chain that contain in the phenolic substances extracting and collect
On have more active hydrogen atom, this hydrogen-like atom be easy reacts with formaldehyde, fatty amine, can be the organic amino group of lotus positive electricity
Group is connected in lignin molecule structure, changes it electrically, when the electropositive of group is increased sufficiently to offset lignin molecule knot
In structure after original elecrtonegativity, lignin molecule starts to show electropositive feature, makes it have excellent complexing, divides
Dissipate property and adhesiveness, simultaneously because the black garlic total phenol substance of preparation contain the strong bioactivity of more free radical scavenging ability at
Point, hydroxyl radical free radical can be removed, inhibits the oxidation reaction as caused by hydrophilic radical APPH, further increases the emulsification of preparation
The stability of agent material.
