Abstract
A gluing process by two-step method and its raw-material formula are disclosed. The raw material formula consists of total water 68-76wt%, total starch 24-32wt%, sheet base 1.5-3.2wt% of total starch and borax 1-2wt% of total starch. The process is carried out by adding into carrier water 30-45wt% of total water, heating to 30-45degree, adding into carrier starch 8-16wt% of total starch, adding into sheet base, agitating while shearing to obtain carrier, adding residual water into water, agitating, adding into residual starch and borax and agitating to obtain the final product. It's simple, cheap and controllable, has fast permeating and curing speed.
Description
Technical field
The invention belongs to starch glue technical field, the particularly glue formula of the adhesive-preparing technology of two-step approach carrier glue and this technology.
Background technology
In corrugated paper board production line, bonding glue has characteristics and the importance of himself, and along with the raising of the corrugated paper board production line speed of a motor vehicle, it is bonding that glue must penetrate into the cardboard gelatinization at faster speed.Starch forms the mixture that comprises water and starch under the effect of certain alkali lye, thereby reduces the gelatinization point of starch self
There are two step glue and single stage method glues in corrugated paper board production line at present, be characterized in that the two-step approach glue is to finish in two jars, above jar make carrier, below a jar make main body, treat to put into again after carrier is made following main body and mix to stir and get final product.The single stage method glue is finished in a jar, and with starch, adding caustic soda and borax got final product after water was added in and is mixed together.
Existing prescription solid content height, water content is many, and made glue is finished in two jars.
The gelatinization point height of starch self (W-Gum 70-72 ℃ etc.) need the adding caustic soda to reduce its gelatinization point.The glue gelatinization point is very big to the influence of cardboard bounding force, simultaneously the speed of a motor vehicle is also had very big influence.The gelatinization point height will cause cardboard to hack, and will be bonding bad, need to reduce the speed of a motor vehicle and obtain enough heats.Particularly produce couch board.Gelatinization point is too low, and glue also comes not just gelatinization of machine infiltration, and cardboard becomes fragile, and is bonding not firm, also might be with regard to gelatinization in pipeline, and blocking pipe etc., the meeting that existing board production has uses additive to control the gelatinization of caustic soda.
Glue viscosity is to be controlled by the starch in the carrier glue.The high glue of viscosity is mobile poor, the infiltration difficulty, and viscosity is low, quick permeation, the starch molecule particle gelatinization fully in the glue, bonding not firm, existing production line also is to use additive to open control viscosity.
Solid content is the per-cent of starch and starch and water in the glue, and what the board production prescription used at present is that starch is few, and the water yield is many, is not suitable for the high speed board production.
The present invention adapts to high speed board production and different paper woods in conjunction with the molecular characterization of starch and the reality of board production, does not use additive, guarantees the flowability and the perviousness of glue, thereby guarantees the bonding of cardboard.
Summary of the invention
The technology that the purpose of this invention is to provide a kind of simple two-step approach glue, promptly in same glue retort, the technology of method glue in two steps is with the prescription of the glue raw material of making this skill.
Knot of the present invention is thought: first water, starch, sheet alkali obtain carrier adding under the gentle agitation condition.Water with capacity dilutes carrier again, makes carrier be dispersed into as far as possible little particle, increases the carrier granule total surface area so that a large amount of starch all combines with carrier as much as possible, and it is many and single carrier granule adds the little glue of single crumb structure of starch to become total quantity.
The present invention at the composition of raw materials that the two-step method making adhesive process in same jar is suitable for is: comprise that weight ratio is total water 68-76%, total starch 24-32%, and account for total starch weight 1.5-3.2% sheet alkali, account for the borax of total starch weight 1-2%.The actual input is the alkaline solution use of sheet alkali being made 20-50%, and alkaline solution should slowly join in water and the starch mixed solution.Above-mentioned prescription is that whole raw materials are always filled a prescription.Owing to be the two-step approach glue, total prescription is divided into carrier compound and main body prescription:
Carrier compound (weight ratio): water accounts for the 30-45% of Total Water, the 8-16% that starch accounts for total amount of starch, and sheet alkali accounts for 100% of alkali;
Main body prescription (weight ratio): water accounts for the 55-70% of Total Water, the 84-92% that starch accounts for total amount of starch, and borax accounts for 100% of borax.
Two-step method making adhesive process in same jar adds two step of the raw material glue that main body is filled a prescription earlier behind the preparation carrier:
The first step earlier prepares carrier in a retort that whipping appts and heating unit arranged: add the water of the 30-45% that accounts for total water weight in the prescription as carrier water in jar, water is heated to 30-45 ℃, add in the prescription and account for total starch weight 8-16% starch as carrier starch, add the sheet alkali that accounts for total starch weight 1.5-3.2% then, the alkaline solution that sheet alkali is made 20-50% uses, and alkaline solution should slowly join in water and the starch mixed solution.Shear agitation obtains carrier;
Second step same jar in obtain carrier after, adding whole water and carrier remaining in total water weight stirs evenly at normal temperatures, add whole starch remaining in total starch weight, stir evenly, add the borax that accounts for total starch weight 1-2%, stir evenly the acquisition finished product, promptly obtain the two-step approach glue glue in same jar.
In above-mentioned whole adhesive-preparing technology, all should stir.
The rotating speed of whipping appts changes for per minute 1400-3000 in the retort.
Advantage of the present invention: the ratio that water accounts for the glue total amount in the prescription is less than existing prescription, can be with less water because in carrier, add add after water stirs remaining starch can both stir with and become glue good, become that viscosity is low, good fluidity, glue that perviousness is strong, the anti-adherend of the curing early of infiltration early moves after making it applying glue, sticking effect is good, the intensity height.Technology of the present invention is simple, branch is finished total overall reaction without the period and is made finished product in a retort, need not divide two retort, reduce equipment cost and operation CONTROL PROCESS, the crumb structure that the cement ratio carrier of this technology system and main body are reacted back mixing glue respectively is littler, perviousness is better, and viscosity is better, and quality is higher.
