CN103102834A - Binder containing modified tree ashes - Google Patents

Abstract

The invention discloses a binder containing modified trees ashes. The binder comprises the following materials: lignosulfonate, nanometer carbon, styrene, hydroxyethyl methylacrylate, acrylic ester, acrylic acid, sodium persulfate, allyloxy hydroxypropyl sodium sulfonate, starch, sodium hydroxide, borax, modified tree ashes, sodium sulfate, ammonium persulfate, dicumyl peroxide DCP, urea, sodium benzoate, ammonium carbonate and water. The binder disclosed by the invention is stable in quality, strong in adhesion force, good in bearing capacity, quick-drying without bubbles and capable of comprehensively improving various performances of a corrugated case. The modified tree ashes are added for reducing the damages of water molecules to the binder, so that the water resistance of the binder is greatly improved; the hydrophilic performance of the glue is reduced, so that the binder has good quick-drying characteristic, thereby facilitating the application on a high-speed corrugated line.

Description

A kind of binding agent that contains modification trees ash

Technical field

The present invention relates generally to a kind of composite caking agent, relates in particular to a kind of binding agent that contains modification trees ash.

Background technology

At present, in watt line production, the tackiness agent of corrugated cardboard mainly uses the amylan tackiness agent, 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, shorter general about 24 hours of shelf-time just began to go bad, body paper is to be made 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, follows closely effectively by glue between lining paper and stupefied peak 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, easily occurs 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.
