Background technique
Corrugated board is also known as corrugated cardboard, is bonded by least one layer of corrugated paper and one layer of boxboard, has preferable
Elasticity and extensibility, mainly for the manufacture of carton, other sandwich and delicate articles packaging materials of carton.Amylan is with valence
Lattice are cheap, adhesive-preparing technology is easy, rate of drying is very fast, adapt to high-speed production is widely used in both domestic and external watt the advantages that requirement
Stupefied paper industry.But original amylan, there are following point, sizing material is easy to produce precipitating, during high temperature in use
Easy mildew damage, bond properties be not high.The above reason causes sizing material in production process to waste, and paperboard properties is unstable, even
It is significantly less than requirements of the national standard.To enhance its performance, the development work of modified starch adhesive is actively developed both at home and abroad, wherein useful
Alum, keto-aldehyde tree refer to, amine, sodium hypochlorite, odium stearate, sodium hydrogensulfite etc. are modified starch, achieves preferable effect
Fruit.
During corrugated board production, the common gelatinization point of starch is 62~72 DEG C, when using pasting on glue, usually
60-80 DEG C, starch is after gelatinization, the amylose penetrated from amylum body, with double helix during cooling down
Form is mutually wound, and the translucent gels of certain elasticity and intensity is formed with, just because of this retrogradation, so that starch gluing
Agent can adhere cardboard.But the common gelatinization point of starch is excessively high, can bring inconvenience.Firstly, glue is in fitting moment
High temperature is encountered, glue surface first solidifies, and forms a tunic shape protective layer and has lockked the moisture content in glue, makes moisture content in glue not
It easily effectively penetrates into paper fiber, to cause false fitting, or fitting is loosely；Secondly, paper fibre can be received because of high temperature
Contracting distortion, it is difficult to keep the original physical property of paper, the coefficient of expansion after glue is inhaled due to various paper is different, easily causes paper
It shrinks and generates warpage, paper causes to shrink in heat-setting process；Again, high temperature is big to the consume of mechanical equipment, also reduces
Machine precision is brought and produces the problems such as unstable；Finally, production temperature is excessively high, so that the operating environment of worker is bad, it is unfavorable
In the high-speed production of worker.Zhou Youming exists《The development of the modified corrugated board amylan of PVA》(chemistry and bonding, 1998 the 3rd
Phase) in, propose the Corn Starch Glue for using and being used for flow line production corrugated board for modifying agent preparation with polyvinyl alcohol (PVA)
Stick achieves preferable effect, but polyvinyl alcohol relative cost is higher, and process is also not easily controlled in practical application.
To sum up, on traditional high temperature and pressure glue paste that there are stickiness is poor, paper is easy to shrink, equipment loss greatly and operation
Many defects, the prior arts such as environment is bad still lack a kind of glue that can apply to constant pressure cryogenic corrugated board production.
