Description
Technical field
This utility model is related to Starch Production technical field, more particularly to a kind of using static reaction production cationic starch
Device.
Background technology
Cationic starch is in starch polymer to introduce tertiary amino or quaternary ammonium group, gives starch cationic characteristic.Sun from
The positive charge of sub- starch makes it be combined with negatively charged substrate, and other negatively charged additives can be adsorbed and are maintained at
In substrate.Cotton fiber in process, when rubbing with metal part, often carries negative charge, for hydrophobic synthetic fibre
Even more serious, if with during cationic starch starching with positive charge, not only having a good bonding force, but also have and disappear
The effect for destaticing.Cationic starch has been used abroad for warp sizing.For example cation composite modified starch, that is, exist
Before cation-modified, cracking drop is first carried out to starch and is gathered, to obtain the starch of low-viscosity, then carry out cation degeneration again.Also
There is amphoteric starch derivant, i.e., Duplex treatment is made to starch using two kinds of denaturants of cation and anion and obtain.Product both contained
There is cation group, contain anionic group again.Cationic starch mainly has two kinds：One kind is starch tertiary amino alkyl ether；Separately
One kind is quaternary ammonium starch ethers.
Cationic starch as a kind of new material, with following purposes：
1. the purposes of the maximum of paper industry cationic starch is made in papermaking using its cationic and strong cohesive property
Inner additive, can improve many physical propertys such as the bursting strength of paper, tension stress, folding strength, resistance to picking, improve Colophonium, vitriol scholar
Sizing efficiency.Paper pulp cationic starch ratio coagulation secures filler and fine fibre, makes the water filtering performance of paper good, improves
Speed copied by paper, also greatly facilitates the pollution for reducing water quality.In addition, cationic starch is to producing preferable papery
The emulsifying of the alkyl ketene dimer used in neutral size and fixation are also effective, and its top sizing in paper, in terms of coating
Application also research.
2. textile industry cationic starch can be used for sizing, increases warp lubricity and wearability, is alternatively arranged as glass fibers
Tie up the protective coating in afterturn and braiding.Due to there is good film property on cationic starch, viscosity stability and with poly- second
The intermiscibility of enol, can be used as fine gauze sizing agent of weaving.Single cationic starch, or and acetic acid, hexenoic acid and butenoic acid etc.
Cationic starch after monomer copolymerization is all have good sizing agent.Cationic starch also acts as laundry finishing agent, by itself plus
The rigidity and flatness of fabric into detergent, can be improved after washing and drying.As the sizing agent of glass fibre, cation
Starch can improve the wearability of glass fibers.
3. because carrying exactly electric charge, can flocculate from suspension flocculant cationic starch negative organic or inorganic granule,
Such as hargil, Titanium Dioxide, coal, carbon, iron ore and mud etc., can be used for draining purification, floating separation and separation, purification and
Concentrate various bioactive substances, such as enzyme, blood plasma, nucleic acid etc..The use that is now employed is water miscible to replace high product and carboxylic
Methylate, the composite modified thing of sulfoalkylation.As its coagulation effect is that molecular mass is proportional corresponding thereto, therefore it
Graft polymers effect more preferable.Additionally, studying which makees ion exchanger, pharmaceuticals probability.
4. cationic starch is alternatively arranged as the fluid loss control additives of the drilling fluids of high salt concentration.
For at present, the production of most domestic cationic starch also has many problems.Mainly production cost is higher and produces
The relatively low problem of moral character energy.Its technique is the inhibitor for adding over dry amount of starch 5% or so in starch milk, with 10% concentration
Lye pH adjustment to after 11.30 or so adds CTA, is warming up to 50 DEG C or so, reacts 6-8h, and this technique CTA conversion ratio is low, medicine
Addition is more, and the response time is long, high energy consumption, and sewage yield is big, so as to production cost is higher.In addition in papermaking application, phase
Same addition, retention and drainage effect are undesirable.
Therefore, the device that a kind of utilization static reaction produces cationic starch is developed, there is urgent researching value not only,
Also there is good economic benefit and commercial application potentiality, this power that exactly this utility model is accomplished is located and basis.
