Description

Carton adhesive specially
Technical field
The present invention relates to a kind of amylum adhesive, relate in particular to a kind of rapid-curing cutback that is exclusively used in binding paper boxType adhesive.
Background technology
Paper products particularly corrugated case are produced, in decades the flower bulb alkali that uses more. Due to its alkalescenceGreatly, the easily moisture absorption, normal accumulation of salt in the surface soil whiting causes paper product distortion, peels off, and even corrodes commodity, causes rottenThe tremendous economic loss such as scrap. Therefore, just replace bubble with amylum adhesive since the fifties abroadFlower alkali, the domestic amylum adhesive that also begins one's study the end of the seventies, be applied to the eighties graduallyPaper product is produced.
Having of disclosing about the formula of amylum adhesive and production technology in prior art is a lot, whereinThe patented technology document that is seen in State Intellectual Property Office website just has hundreds of. Wherein comparatively typicalPatent application technology have: Chen Baoyuan has proposed " an one by name on October 17th, 1996Cold made high-strength quick-acting binder and method for making thereof " application for a patent for invention (number of patent application is 96120089.8), disclose a kind of for carton produce amylum adhesive, by cornstarch 150~180,Reinforcing agent 3~10, catalyst 2~8, clorox (10% content) 30~50, caustic soda (95% content)15~25, borax 3~7, water 800~1000, sodium thiosulfate 1~4, in certain sequence oftenTemperature is lower to be formed through certain hour stirring reaction. The advantage of this patent application technology is that Production Time is short,Technique is simple, makes and use not limited by temperature conditions, and properties of product are stable, and bonding strength is high,Rate of drying is fast, and cost is low.
Yangjiang City Huamei Printing Packaging Co., Ltd. has applied for " a kind of quick-drying on February 6th, 2004Type amylum adhesive " patent of invention (number of patent application is 200410015298.X), this application public affairsOpen a kind of fast drying starch adhesive, produced by following methods: has put into 10 parts of starch to stir (1)Mix in tank and add 40 parts of water to stir, then add 0.8~1 part of sodium hydroxide solution, oftenThe quaternization of the lower reason row of temperature; (2) add 0.04 part of hydrogen peroxide, 30 parts of water to carry out oxidation reaction 40Minute; (3) add 0.04 part of tributyl phosphate, 0.04 part of borax, 0.15 part of sodium carbonate, 0.01Part magnesium sulfate, stirs 10 minutes, makes liquid reactions become milky or light beige. This technologyFeature be that product density is little, bonding force is strong, fast drying, good fluidity, not strike-through, not skinning,Be difficult for jaundice, and production cost is low, production equipment is simple.
Henan Xindoucai Printing Co., Ltd. has applied for " cornstarch on August 13rd, 2008Adhesive " patent of invention (number of patent application is 200810141014.X), its technical scheme is: onePlanting corn starch adhesive agent prepares according to following step: (1) first adds 50 weight parts waters in container,Then add the hydrogen peroxide of 2~2.5 weight portions to stir; (2) in above-mentioned gains, addThe cornstarch of 10~15 weight portions stirs and obtains glue; (3) get 0.04~0.08 weight portionFerrous sulfate join in second step gained glue after adding the water dilution of 1.5~2.5 weight portions, stirAfter mixing evenly, leave standstill 20~40 minutes; (4) to adding 25~35 weight portions in the 3rd step gainsWater, stirs; (5) get the NaOH of 2~2.5 weight portions, add 6.5~7.5 weight portionsWater dilution after join in the 4th step gains and stir 8~15 minutes; (6) get 1.2~1.5 weightsAfter adding the dissolved in boiled water of 2.5~3.5 weight portions, the borax of amount part joins in the 5th step gains,Stir 4~8 minutes; (7) in the 6th step gains, add proper quantity of defoaming agent and 4.5~5.5 weightThe water of part, stirs. Its advantage is nonpoisonous and tasteless, and strong adhesion can be used for food capableIn industry packaging.
Jiangyan City Huaguang Chemical Paper Co., Ltd. has proposed by name " shallow lake on November 25th, 2003Powder adhesive (SSS-85) " application for a patent for invention (number of patent application is 200310106411.0),Its technical scheme is: a kind of amylum adhesive, taking cornstarch and water as main component, contains steadyDetermine agent, oxidant, terminator, in composition, add synthetics, catalyst. With conventional modificationStarch is compared with phosphate ester starch as oxidized starch, and the feature of this technical scheme is that adhesive is stuck with paste liquidRetrogradation is little, compatibility good, is conducive to prepare high solids content, low viscous pigment coating, itsPaper properties is superior, and has outstanding cost performance.
Above-mentioned patent has contained most starch producing technology technology. But from disclosedRelated art scheme, all exists some shortcomings part, and some production cost is high, and some is dryDry speed is slow, and some is that quality is unreliable. From market survey, common requirements one on marketPlant the amylum adhesive product that rate of drying is fast, cost is low.
Summary of the invention
The present invention seeks to overcome weak point of the prior art, provide a kind of rate of drying fast,The fast drying starch adhesive that cohesive is good, cost is low.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical programs: oneCarton adhesive specially, is made by the raw material of following weight proportion: 25~30 parts of cornstarch,50~55 parts, water, 8~10 parts, NaOH, 0.12~0.16 part of boric acid, composite oxidant 0.3~0.45 part, 0.3~0.45 part of nanometer sepiolite powder, 0.05~0.2 part of alum solution.
Preferred version of the present invention is: 25 parts of cornstarch, 50 parts, water, 9 parts, NaOH,0.2 part of boric acid, 0.3 part of composite oxidant, 0.3 part of nanometer sepiolite powder, alum solution 0.15Part.
As further improvement of the present invention, described composite oxidant is by potassium permanganate and inorganic acidMix in 1:3~7 ratio.
Advantage of the present invention is:
1, good combination property of the present invention, bond properties is more excellent. With regard to the oeverall quality of amylum adhesive andSpeech, it depends primarily on the oxidative deformation process of starch in preceding working procedure. Generally speaking, starch is stickyThe oxidant that mixture is selected is all potassium permanganate. But in actual production process, we findIff the potassium permanganate using single as oxidant, effect is also also bad. Therefore, through excessiveAfter amount test, the present invention has adopted potassium permanganate and inorganic acid has been blended together to composite oxidant, thus energyControl better oxidation process, promote oxidation effectiveness. Select contrast through actual, the present invention is obtainedAmylum adhesive higher by 15% than adopting conventional single its viscosity of potassium permanganate oxidant, whiteness and thoroughlyLightness is wanted high 25% left and right.
2, the drying effect of adhesive is good. Adhesive adds boric acid, the starch that it can make short chain withIts hydroxyl or hydroxyl and boron atom form complex compound, irregular crosslinked by these, form nettedStructure, has crosslinked viscosifying action, is conducive to improve initial bonding strength and accelerates rate of drying, also playsAnticorrosion, antiseepage effect.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described.
Embodiment 1: under room temperature, get 25kg cornstarch and mix with 50kg water, slowly add alsoStir to milky starch slurry, get NaOH 8kg and be mixed with certain density hydroxideSodium solution also slowly adds it in starch slurry, obtains the milky white thickness gelatinized corn starch of pre-gelatinization; ThenGet potassium permanganate 0.08kg, phosphoric acid 0.24kg, prepared certain density composite oxygen with hot waterAgent solution, adds in above-mentioned gelatinized corn starch; Get again boric acid 0.12kg hot water dissolving and be made into finite concentrationSolution add gelatinized corn starch to form glue, finally get nanometer sepiolite powder 0.3kg and add in glueObtain eventually oxidized starch adhesive, adhesive constantly stirred and slowly adds alum solution 0.15kg again,Finally obtain manufactured goods.
