Description

The caking agent that a kind of cohesiveness is strong

Technical field

The present invention relates generally to a kind of caking agent, relates in particular to the strong caking agent of a kind of cohesiveness.

Background technology

At present, the tackiness agent of corrugated cardboard mainly uses the amylan tackiness agent in watt line production, we know, the stripping strength standard of existing Starch Adhesive is 5.88n/m2, its production technique is single stage method glue and two step method glue, glue is divided into again cold glue and two kinds of methods of hot glue, facts have proved, adopts the hot adhesive-preparing technology binder performance more made than cold adhesive-preparing technology good.But, existing tackiness agent can not be stablized, glue kinematic viscosity descends very fast, shelf-time just began to go bad in short general about 24 hours, body paper is to be made of multiple fiber molecule, starch adhesive is penetrated into the fiber and forms the glue nail of root top shape from the surperficial pore of paper, follows closely by glue between lining paper and the stupefied peak effectively to be bonded together.The high-strength corrugated board papery is better, and tightness is high, and the top sizing pore is blocked, and general glue perviousness is relatively poor, occurs easily false stickingly, bubbles, the quality problems such as come unstuck.Address this problem, must guarantee glue stability, will be accurate through the poor starch thickener of the viscosity high workability of overcuring, in right amount, spread upon equably on the corrugation crest line, satisfy this processing requirement of high-strength corrugated board bonding mechanism, must manufacture the glue performance aspect and be resolved.Dry slow, come unstuck distortion, moisture absorption.
