A kind of stalk-starch conversion synthesis early strong concrete water-reducing agent preparation method and System

Technical field

The present invention relates to cement water reducing agents, and in particular to a kind of stalk-starch conversion synthesis early strong concrete diminishing The preparation method and system of agent.

Background technique

Currently, along with petrochemical industry needed for preparing the high performance petroleum base polycarboxylate water-reducer of a new generation of concrete admixture The increasingly scarcity of raw material, leads to the outstanding problem of price rising all the way, constrains the high performance polycarboxylate water-reducer of a new generation Fast development keeps its production cost constantly soaring, so that this has than naphthalene system, fatty family, sulfamate system, Lignins The polycarboxylate water-reducer of the higher performance advantage of equal water-reducing agents cannot widely popularize application in building trade.Domestic and foreign scholars are close Begin one's study low cost and high performance water-reducing agent for several years.

Water-reducing agent is a kind of important concrete admixture, and in China, application is more widely lignosulfonates at present Class water-reducing agent and naphthalene water reducer, there are many deficiencies for both water-reducing agents, and it is imperative to develop new water-reducing agent kind.Together When, problem that China's water-reducing agent industrial expansion is faced with and improves performance, reduces cost and all various aspects such as environmental-friendly.With The raising of environmental protection standard, some techniques will be eliminated gradually including naphthalene water reducer etc., and high-performance polycarboxylic acids water reducing agent Price factor it is allowed of no optimist in the popularization and application foreground in China.Therefore, research and development is environmental-friendly, performance is up to standard And the new and effective water-reducing agent for meeting China's level of economic development becomes an important research topic.According to water-reducing agent performance It is different with use occasion, and be divided into retardation setting type, slow-release, early-strength, collapse protection type, anti-mud anti-salt type, comprehensive performance type etc., in recent years No matter comes domestic and foreign scholars and its production technician and a large amount of research has been carried out to the preparation method of the water-reducing agent of different function It is all to achieve good achievement in theoretical research or design production practices research.But it's a pity that not having also at present There are the synthetic method method and production system developed and be suitable for producing biomass modified early strong concrete water-reducing agent.

About the progress of inexpensive polycarboxylate water-reducer, be mainly reflected in use biomass-based renewable raw materials as The main method for reducing polycarboxylate water-reducer, that reports at present is mainly modified by cellulose, hemicellulose, starch, single polysaccharide etc. Application in water-reducing agent afterwards mainly has sulfonation, esterification, etherificate, amidation etc. to its method of modifying.Starch according to its purposes not Different method of modifying is taken together, wherein sulfonated starch and etherification starch are that sulfonic group and carboxymethyl are introduced on starch molecule The product of generation, sulfonated starch and etherification starch, which are used as water-reducing agent, to be had certain feasibility in theory and practices validity, is led to It crosses starch conversion to be developed as novel high efficiency water reducing agent and realize industrialization, to alleviate face in current China's water-reducing agent application The problems faced, while completely new field is opened up for the application of starch base natural macromolecular material.But unfortunately, for this The research of aspect does not enter the engineer application stage mostly also in laboratory stage mostly.

Agricultural crop straw is the failure to the cheap biomass material made full use of, including wheat, rice, corn, potato, oil The remainder of material, cotton, sugarcane and other crops after harvesting seed.China is large agricultural country, every annual output crops straw It is more than 700,000,000 tons of stalk, most of to be still incinerated, it results in waste of resources and environmental pollution.Agricultural crop straw is utilized in the world As the strategic industry of 21 century Renewable Energy Development resource, the resource utilization of agricultural crop straw primarily focuses on chemical industry With the exploitation of construction material.Agricultural crop straw is a hot spot as construction material application study at present, such as.But directly as subtracting The research of the raw material of aqua is seldom.The main component of stalk is the biology bases macromolecular such as cellulose, hemicellulose and lignin, point In son containing a variety of functional groups such as ether, carbon-to-carbon double bond, propylene alcoholic extract hydroxyl group, phenolic hydroxyl group, carbonyl, methoxyl group, carboxyl, phenyl ring and Chemical bond can be etherified, is esterified, sulfonation, the graft copolymerizations such as amidation and copolymerzation with cross-linking reaction, products obtained therefrom have particularity Energy.

As environmental protection is gradually taken seriously, people are also concerned about itself and environment while pursuing construction material performance Safety problem, this is just badly in need of exploring synthetic method, researchs and develops a kind of new high efficiency water reducing agent.Straw biological base water-reducing agent Occur, has adapted to the demand in national policy and market, but work is not entered also in laboratory stage for the research of this respect The journey application stage.There is straw biological base water-reducing agent preferable water-reduction and slow setting, guarantor to collapse effect, and agricultural crop straw money Source is abundant, cheap, itself is nontoxic, degradable.With preferable industrial prospect, but it is just in the Preliminary Study stage at present, It is not used widely.Nearly 2 years, scholar constantly explored the synthesis of straw biological base water-reducing agent by being modified to stalk Method.

Currently, the research directly biomass straw for water-reducing agent is reported seldom, it is that separation is extracted from stalk mostly Cellulose, lignin out, or the black liquor waste obtained by stalk production papermaking, ethyl alcohol is raw material, the study on the modification for water-reducing agent Or it is studied with polycarboxylic acids water reducing agent compositional.

The research of lignin modification water-reducing agent, 101337789 A of Chinese patent CN " wheat straw alkali lignin condensation and modification preparation Wheat straw alkali lignin is added in the water of 4.4~5.5 times of weight and dissolves by the method for water-reducing agent ", and wheat straw alkali lignin weight is added 0.6~0.9% copper sulphate, adjusting pH value with soda bath is 10~11, adds wheat straw alkali lignin weight 45~55% Anhydrous sodium sulfite is warming up to 88~92 DEG C, reacts 4~5h, and sulfonated product is made, and quantitative formaldehyde is 11.6 in pH value Under the conditions of~12.0,65~75 DEG C, condensation reaction is carried out, water-reducing agent is made.Water-reducing agent water-reducing rate made from this method is low, can only It is used as most common water-reducing agent.101759856 B of Chinese patent CN " preparation method of sodium lignin sulfonate water reducer ", The black liquor generated using corncob, corncob acid hydrolysis slag, bagasse or corn stover by soda boiling by coarse filtration, surpasses as raw material Filter membrane concentration, sulfonation and spray drying, prepare the sodium lignin sulfonate water reducer of low water content, and the technique is to environment without dirt Dye, process are simple, low in cost, but stalk cannot make full use of, and waste is serious.106698993 A of Chinese patent CN " a kind of polycarboxylate water-reducer ", is sized mixing using waste white mud, is heated, then is mixed with corn stover, and dodecyl sulphate is added Sodium, dry extruding is blocking after stirring, and acidleach obtains hydrolyzate, and it is 6.0~7.0 that stalk hydrolyzate, which is transferred to pH value, using CaO, obtains The hydrolyzate arrived is added in polycarboxylate water-reducer after drying, oxidation, sulfonation, after mixing evenly with ultrasonication 1~ 2h obtains modified poly carboxylic acid series water reducer.This method main advantage is that papermaking wastewater is used to prepare to polycarboxylate water-reducer, energy It is enough to turn waste into wealth well, pre-treatment is carried out to corn stover using highly basic therein, so as to which preferably pickling carries out Hydrolysis.Its essence is compounded using the Sulphonation of Lignin in stalk with water-reducing agent.A kind of Chinese patent CN 102936110A " wood The copolymerized high-performance water reducing agent of mahogany sulfonate-polycarboxylic acids and preparation method ", it is poly- with lignosulfonates, methacrylic Ethylene oxide ether and acrylic acid directly synthesize under the action of ammonium persulfate, and sodium hydroxide is neutralized and obtained.Its essence is sulfomethylated lignins Sulfonate modified polycarboxylate water-reducer.

Directly biomass straw is used for the research of water-reducing agent, mainly there are two reports: Chinese patent at present CN106279574 A " a kind of polycarboxylate water-reducer and preparation method thereof modified using stalk ", the first step, stalk pretreatment: After stalk is crushed, diluted acid is added, 18-36h is impregnated after being uniformly mixed, filter and rinses stalk to neutrality with clear water；The Two steps are prepared by the modified polycarboxylate water-reducer of stalk: methylallyl polyoxyethylene base -1000, methylallyl are gathered Four reflux units and constant pressure addition is added in oxyethylene group -2400, maleic anhydride, acrylamide, methylpropene sodium sulfonate and stalk Funnel, constant pressure funnel is interior to be added ammonium persulfate, starts that initiator ammonium persulfate is added dropwise, and rate of addition is 2-4 drop/s, is added dropwise After keep the temperature 4-5h；It is cooled to 35-45 DEG C, adjusts pH to 6.8-7.2, the polycarboxylic acids diminishing modified using stalk can be obtained Agent.105713164 B of Chinese patent CN " a kind of aliphatic water reducing agent and preparation method thereof using stalk preparation ", passes through straw Stalk pickling, stalk modified aliphatic water reducing agent and etc. be prepared.Specifically: stalk is pre-processed, by corn stover or After wheat stalk crushes, diluted acid is added, 18~36h is impregnated after being uniformly mixed, filter and rinses stalk to neutrality with clear water； Water is added in a kettle, sodium sulfite is then added, dissolves；Acetone, sulfonation 8 are added in sodium sulfite solution upon dissolution ~12min；Then pretreated stalk is added, is stirred to react 20~40min；Formaldehyde is added into solution, at 90~95 DEG C 1~2h is reacted again, prepares stalk modified aliphatic water reducing agent.The technology efficiently uses straw refuse resource, changes It has been apt to the disadvantage of existing aliphatic water reducing agent retarding effect difference, has improved the application range of aliphatic water reducing agent, reduce life Produce cost.But this two results of study are the lab scale shake flask test in laboratory, first is that not proposing to the crushing of stalk fine crushing Degree and method, only say that stalk crushes, second is that stalk hydrolysis can be brought into using conventional dilute hydrochloric acid or dilute sulfuric acid hydrolysis The chloride ion and sulfate ion of amount, influence water-reducing agent performance, third is that not proposing the imagination and design of industrial test, distance There are also very big distances for industrialization production device and production system.
