The present invention is number of patent application 201510681204.0, and patent name is：A kind of modified Cardanol derivative diminishing
Agent and preparation method thereof, the applying date are the divisional application on October 19th, 2015.
Technical field
The invention belongs to field of fine chemical, more particularly to a kind of modified Cardanol derivative water-reducing agent and its preparation side
Method.
Background technology
Anacardol is the principal component of cashew nut shell liquid.Cashew nut shell liquid is the agricultural by-products in cashew nut process, by natural
Cashew nut shell is through pyrolysis or supercritical CO2The methods of extraction sepia liquid of vicidity obtained.In cashew nut shell liquid containing cashew acid,
The main components such as anacardol, card phenol and dimethyl card phenol.And the cashew nut shell liquid of separate sources also often contains a small amount of polymer and lacks
Measure component.Directly de- shuttle becomes anacardol to cashew acid in commodity cashew nut shell liquid, and wherein anacardol content is up to 90%.
Anacardol is the highly useful raw material of synthetic resin and many industrial products.Since its abundance, price are low
It is honest and clean, there is highly important development and application to be worth.Since nineteen twenties, people do the research of anacardol
Extensive work all achieves fruitful progress in composition, structure, property and its application etc..Anacardol is with alkene
Belong to the natural monophenol derivative of unsaturated long side carbochain base, structure is similar to laccol.The existing aromatic compound of anacardol
Feature, and similar to aliphatic compound feature, meanwhile, the phenolic hydroxyl group on phenyl ring makes it have the property of phenols.Obviously,
The special construction of anacardol imparts anacardol with special chemical property.Anacardol chemically reacts feature：Some reactions
A certain group is only occurred in, some is then extremely complex.Main reaction has hydrogenation, oxidation reaction, sudden reaction, esterification instead
Should, etherification reaction, nitration reaction, sulfonating reaction, polycondensation reaction etc..
Using the sulfonating reaction of anacardol, using anacardol as raw material, synthesis anacardol based surfactants have largely
Document report, and anacardol based surfactants have good surface-active.The present invention is with the sulfonated products cashew nut of anacardol
Sulfocarbolate is raw material, and on carbochain unsaturated bond, cashew nut sulfocarbolate carries out polyaddition reaction, generation with functional monomer
The modification Cardanol derivative polymer of excellent surface activity with several functions group, this polymer have good subtract
Water effect can be used as cement water reducing agent.Product water-reducing rate of the present invention is more than 18%, reaches high efficiency water reducing agent level.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of modified Cardanol derivative water-reducing agent and its
Preparation method, the stabilizer can more preferably improve the stability of water-coal-slurry.
To achieve these goals, the present invention uses following technical scheme：
A kind of modified Cardanol derivative water-reducing agent, the raw material components matched by following portions by weight are made：
The unsaturation ethylene oxidic ester is glycidyl acrylate or glycidyl methacrylate；The insatiable hunger
With carboxylic acid and/or its salt for any one in acrylic acid, sodium acrylate, methacrylic acid and Sodium methacrylate or two kinds with
On with it is arbitrary than mixing mixture；The vinyl phosphoric acid and/or its salt are vinyl phosphoric acid, vinyl phosphoric acid sodium and ethylene
Any one in base potassium phosphate or the two or more mixtures with arbitrary ratio mixing；The unsaturated amides for acrylamide or
Methacrylamide.
A further improvement is that：The initiator be sodium peroxydisulfate, potassium peroxydisulfate and ammonium persulfate in any one or
Two or more is with the arbitrary mixture than mixing.
A further improvement is that：The alkaline conditioner is sodium hydroxide, appointing in potassium hydroxide, sodium carbonate, potassium carbonate
Meaning is one or more kinds of with the arbitrary mixture than mixing.
A kind of preparation method of modified Cardanol derivative water-reducing agent, is achieved by the steps of：
(1) cashew nut natrium phenolsulfonicum, the unsaturation shrink of 5~10 parts by weight that 10~40 parts by weight are added in into reaction kettle are sweet
Grease, the unsaturated carboxylic acid of 5~20 parts by weight and/or its salt, the vinyl phosphoric acid of 0.5~5 parts by weight and/or its salt, 0.5~
Stirring is opened after the unsaturated amides of 5 parts by weight and the water of 21~35 parts by weight, and begins to warm up heating；(2) treat that temperature rises to
At 65~100 DEG C, start that the initiator solution that mass percent concentration is 1~10% is added dropwise, this initiator solution is by 0.05~2
The initiator of parts by weight and the water of 9~20 parts by weight are formulated；Time for adding controls the temperature control at 0.5~4 hour, dropwise addition
System is at 75~100 DEG C；(3) the alkaline conditioner adjustment acid-base value of 0.1~5 parts by weight is added in after dripping, after 0.1~1 hour,
Cooling discharge is to get the modified Cardanol derivative water-reducing agent.
Compared with prior art, the present invention has following remarkable result：
1st, the present invention is using cashew nut natrium phenolsulfonicum as starting material, using cashew nut natrium phenolsulfonicum on carbochain unsaturated bond, waist
Fruit sulfocarbolate can with functional monomer carry out polyaddition reaction, so as to obtain containing ester group, carboxyl, phosphate, amide groups,
The modification Cardanol derivative water-reducing agent of the excellent surface activity of the several functions group such as sulfonic group, the items of this water-reducing agent
Related quality criterion requirement can be can reach, water-reducing rate is high, the slump keeps good, dispersion flows better performances, air content is low
And later strength is high；
2nd, primary raw material cashew nut natrium phenolsulfonicum of the invention is by this abundance of anacardol, natural reproducible biology
The sulfonation of matter product and obtain, meet the requirement of economic environmental protection；
The product processes are simple, mild condition, and production process charging, condition are all easy to control, entire technical process
It is discharged without " three wastes ", is a kind of environmental type, pollution-free cleanly production technique.
