Abstract
The present invention is relevant novel method of making adhesive for corrugated paperboard.Employing starch is raw material, obtains with chemical processes such as oxidation, gelatinization, neutralizations.The used starch of the present invention is corn powder or Ipomoea batatas industrial starch or wheat starch.The tackiness agent that makes with present method can long-term storage, uses under the room temperature about 30 ℃ of suiting, and is neutral pollution-free to packing material.Fabrication cycle is short, and equipment is simple.
Description
The manufacture method of a kind of manufacturing corrugated cardboard (making fluting board tr is used) tackiness agent.It is to use starch as main raw material, makes with chemical process.
At present, the domestic bubble flower alkali that generally adopts is as the fluting board tackiness agent, and this tackiness agent alkalinity is big, the easy anti-alkali of the moisture absorption, and papery is melted in corruption, makes the carton embrittlement case that looses, the while dirty cargo.
In recent years, more domestic units are for adapting to the needs of China's unit batch production, work out several new adhesives, but all exist tackiness agent instability (can not long-term storage), glue runs stupefied in the adhesion process, rate of drying is too slow, needs problems such as high temperature production when bonding, can not satisfy the production needs.
Though occurring some new adhesives such as composite adhesives abroad in recent years waits and replaces bubble flower alkali, but be confined to when it uses to require to heat, the conditions such as modern large-scale carton production of high temperature, quick-binding, its complex process, equipment is various, all can't adapt to the working condition of most medium and small carton factories of China various places.
Purpose of the present invention just provides a kind of pollution-free (promptly requiring tackiness agent to be neutral), energy long-term storage, suitable (room temperature is more than 30 ℃) at normal temperatures and the tackiness agent that can use under the equipment that uses the production of bubble flower alkali tackiness agent.
The present invention is to be main raw material with starch (containing pure starch more than 70%), and (oxygenant is an oxydol H by oxidation
2O
2) starch is carried out modification, with the viscosity (flowability) of Starch Adhesive after the reduction gelatinization, to adapt to the requirement of high speed machine gummed.Before this, add a certain amount of catalyzer (ferrous sulfate) FeSO
47H
2O is to promote its oxidizing reaction.Oxidizing reaction 40-60 minute, starch by the brown degree of greyish white flavescence after, highly basic (sodium hydroxide) NaOH that adds capacity immediately carries out gelatinization.Gelatinization to the solution retrogradation to the malt sugar shape, continue again to stir and add acid (sulfuric acid, hydrochloric acid, citric acid, oxalic acid) after 10-20 minute to stop gelatinization, regulate the viscosity and the pH value of its solution simultaneously, (requiring pH value is 7-8) back adds an amount of complexing agent (borax) and stablizer urea-formaldehyde resin or and modified resin.Begin to be about 1-2 hour from oxidation to being pasted into the glue whole process.
It is neutral that the glue made from the present invention is, pollution-free to goods, long-term storage, and its binding property can not change, can be bonding under general room temperature, and its binding appts, technology and identical with binding appts, the technology of the colored alkali of bubble.
Do raw material (per kilogram is by 0.5 yuan) with corn powder, the per kilogram corn powder can be produced 5-6 kilograms in tackiness agent, and the raw materials cost of per kilogram tackiness agent is 0.15 yuan.Do raw material with Ipomoea batatas industrial starch (by 0.5 yuan of per kilogram), the per kilogram sweet potato starch can be produced tackiness agent 6-7 kilogram, and the raw materials cost of per kilogram tackiness agent is 0.14 yuan.
Embodiment:
Take by weighing decortication, remove embryo, the granularity that obtains with levigation method is 80-100 purpose W-Gum 100 grams, is positioned over 500 milliliters, is equipped with in the there-necked flask of agitator, adds 200 milliliters of clear water, and is heated to 45-50 ℃ with water-bath, stirs simultaneously.When temperature reaches 40 ℃, ferrous solid 2 grams of catalyst sulfuric acid are added, and proceed to stir, slowly splash into after 10 minutes through carrying out oxidizing reaction with the 4 milliliters of hydrogen peroxide (30% content) after the dilution of 20 ml waters, observe the oxidation situation simultaneously, when Semen Maydis powder becomes yellowish brown gradually by canescence, promptly be acid, pH value can be learnt by acid number for the 3-4(degree of oxidation) time, add 8 milliliters in clear water, and carry out gelatinization with the aqueous sodium hydroxide solution of 65-70 milliliter 10%, it is slow that gelatinization speed is wanted, and impose powerful the stirring, be scattered paste shape for gelatinization to glue, and can play when silk, regulate pH value gradually for 100 milliliters with sulfuric acid immediately, promptly reach neutrality when pH value reaches 7-8() time adhesive viscosities descend rapidly.Add the borax NO of 1-2 gram this moment again
2B
4O
710H
2The urea-formaldehyde resin of O and 4-20 gram.And water is adjusted to suitable adherent viscosity.Semen Maydis powder accounts for the 16-20% of total binder.
