Description

A kind of high-strength waterproof corrugated cases adhesive

Technical field

The present invention relates generally to a kind of bonding agent, relates in particular to a kind of high-strength waterproof corrugated cases adhesive.

Background technology

At present, watt line produce in the adhesive of corrugated board mainly use amylan adhesive, we know, the peel strength standard of existing amylum adhesive is 5.88n/m2, its production technology is one-step 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 adhesive can not be stablized, glue kinematic viscosity declines very fast, shorter general about 24 hours of resting period just started to go bad, body paper is to be made up of multiple fiber molecule, starch adhesive is penetrated into fiber and forms the glue nail of root top shape from the surperficial pore of paper, between lining paper and stupefied peak, is followed closely effectively and is bonded together by glue. High-strength corrugated board papery is better, and tightness is high, and top sizing pore is blocked, and general glue permeability is poor, easily occurs false stickyly, bubbles, the quality problems such as come unstuck. Address this problem, must ensure glue stability, by accurate starch thickener poor the viscosity high fluidity through overcuring, in right amount, spread upon equably on corrugation crest line, meet this technological requirement of high-strength corrugated board bonding mechanism, must manufacture glue performance aspect and be resolved. Dry slow, come unstuck distortion, moisture absorption.
