In order to reach better technique effect, tackiness agent of the present invention is comprised of following each component: expanded corn starch, sodium bentonite (or sodium matter montmorillonite), Whitfield's ointment and sodium Diacetate; Preferably, the weight part of each component is: expanded corn starch 90-98 part, sodium bentonite (or sodium matter montmorillonite) 1-6 part, Whitfield's ointment 0.5-4 part, sodium Diacetate 0.5-4 part; Preferred, the weight part of each component is: 96 parts of expanded corn starchs, 2 parts of sodium bentonites (or sodium matter montmorillonite), 1 part of Whitfield's ointment, 1 part of sodium Diacetate;
Wherein, described expanded corn starch can be bought by commercial sources and obtain, for example: can reach mechanical company limited available from converging in the Liyang city;
Described expanded corn starch also can prepare with reference to following methods: get clean corn through decortication, break, extraction maize germ, make the corn particle, reach without skin without navel.It is expanded that the corn particle is directly put into bulking machine, pulverizes with pulverizer at any time after expanded, sieves, and collects 200 order fine powders, gets final product to get expanded corn starch.
27% amylose starch is arranged, 73% amylopectin in the W-Gum.Amylose starch is not the straight chain of extended configuration, but because the effect of intramolecular hydrogen bond is curled into spirrillum.This closelypacked coil type structure of amylose starch is conducive to form intermolecular hydrogen bonding, is unfavorable for forming hydrogen bond with water molecules, so amylose starch is not soluble in cold water.Amylopectin has the structure of hyperbranchedization, is comprised of many short chains, because the hyperbranched structure of amylopectin, easy and water molecules forms hydrogen bond, so amylopectin is soluble in cold water, but adhesiveproperties is relatively poor.I.e. no matter amylose starch or amylopectin, the bonding effect of itself is all bad, all can not directly use as tackiness agent, must could use after peroxidation or gelatinization.The pasted starch initial bonding strength is good, and bonding strength is large, can directly use as tackiness agent.
The at present gelatinization of starch mainly is heating gelatinization and alkali gelatinization, and what we selected is another kind of gelatinizing method: expanded gelatinization, and good through trial effect.According to expanded principle, the corn particle of pulverizing is packed in the bulking machine, carry out heating and pressurizing and mechanical effect, make corn be in high-temperature high-pressure state.At this moment, rapidly the sealing cover of bulking machine is opened, in this moment, because corn is down to suddenly the normal temperature and pressure state, huge energy discharges, and is the water vapor evaporation of superheat state, inflatable about 2,000 times of its volume, thus produced the swelling pressure.The huge swelling pressure make corn tissue suffer powerful explosion extension effect, corn is caused countless trickle spongy structures, i.e. corn puffing.
Corn shows in macroscopic view that through after expanded the volume of corn increases several times to tens times, porous, and spongy, quality is loose; Variation has occured in the molecular structure that shows W-Gum internal structure and chemical ingredients at microcosmic, the hydrogen bond rupture between starch chain, and chain is moved, and starch small grain disintegrates, degraded, α-change.In puffing process, along with the degraded of starch, a part of side chain of amylopectin is cut, and the fracture of α-1,6 glycosidic bond has namely occured, and the ratio of short amylose starch is increased.The expanded degraded that not only causes amylopectin, and can also cause α in the amylose starch-Isosorbide-5-Nitrae glycosidic bond fracture produces small-molecule substance, namely sends out dextrinizing farinose.These all make original hydroxyl in spiral coil expose in the outside, can be with moisture the fracture of α-1,6 glycosidic bond, the ratio of short amylose starch is increased.The expanded degraded that not only causes amylopectin, and can also cause α in the amylose starch-Isosorbide-5-Nitrae glycosidic bond fracture produces small-molecule substance, the dextrinizing of namely sending out dextrinization farinose.These all make, and hydroxyl in the original spiral coil is exposed can to form hydrogen bond with water molecules outside, makes original soluble in water also not become soluble in water.Be that corn starch structure after expanded is loose, spongy, soluble in water.Infiltrate in water, expand, viscosity increases, and initial bonding strength strengthens, and bonding strength obviously improves, this just so that expanded W-Gum can directly use as tackiness agent.
Montmorillonite is a kind of aluminium silicate mineral, and the multiple performances such as swelling property, dispersiveness, suspension, oilness are arranged, and is used widely in industrial or agricultural and national defense industry.Wilkinite (montmorillonite) can be done binding agent, suspension agent, thixotropic agent, stablizer, purification and decoloration agent, casting resin, feed, catalyzer etc. because good physical and chemical performance is arranged.Each chief component composition of sodium bentonite sees Table 1.
