A kind of processing method of highly intensified corrugated paperTechnical field
The invention belongs to corrugated paper processing technique fields, and in particular to a kind of processing method of highly intensified corrugated paper.
Background technique
Corrugated board is the adherend of a multilayer, it is at least made of one layer of waveform core paper interlayer and a layer paperboard.Existing corrugated paper intensity is lower, it is difficult to satisfy the use demand.
Summary of the invention
The purpose of the present invention is to propose to a kind of processing method of highly intensified corrugated paper, overcome the prior art it is above-mentioned notFoot, which increase the burst index of corrugated paper and ring crush indexs to improve corrugated paper so that this corrugated paper has higher intensityThe service life of case meets market use demand, is conducive to product promotion.
In order to reach above-mentioned purpose of design, The technical solution adopted by the invention is as follows:
A kind of processing method of highly intensified corrugated paper, comprising the following steps:
Step 1: preparing body paper paper pulp；
Step 2: reinforcing agent is added into body paper paper pulp；
Step 3: being heat-treated to original paper；
Step 4: the surface to original paper carries out gluing processing；
Step 5: compound, obtained corrugated paper is carried out to original paper by Corrugating Machine；
Step 6: cooling treatment after dry, obtains highly intensified corrugated paper.
The body paper paper pulp includes the various composition of following mass fraction: 8 parts of agricultural crop straw, 5 parts of Hickory, and white birch8 parts of wood, 3 parts of pear wood, 2 parts of cassia siamea.
The reinforcing agent includes 8-10 parts of polyamidoimide, 2-4 parts of polyhydroxy chemical coupling agent, phosphorous acid by weight3-5 parts of salt, 2-5 parts of ethylene copolymer, 5-10 parts of stabilizer.
In step 4, the binder that gluing processing uses includes following components by weight: 160 parts of starch, sodium bicarbonate15 parts, 10 parts of strong catalyst, 2 parts of zinc borate, 6 parts of ethylene glycol amine, 10 parts of toluene di-isocyanate(TDI), 3 parts of alum, defoaming agent 5Part, 30 parts of gelatine, 3 parts of benzoyl peroxide, 8 parts of polyalcohol, 20 parts of isopropanol, 9 parts of calcium stearate, 7 parts of aluminum aluminum sulfate, yin from5 parts of sub- surfactant, 220 parts of water.
The binder production method the following steps are included:
Water is added in step 1 in a kettle, is heated to 80-90 DEG C, then plus starch stir 6 minutes, be gelatinized；
Step 2, by sodium bicarbonate, zinc borate, ethylene glycol amine, toluene di-isocyanate(TDI), alum, gelatine, benzoyl peroxide firstAcyl, calcium stearate, aluminum aluminum sulfate, anionic surfactant are dissolved by water, are added in reaction kettle and are stirred 25 minutes；
Polyalcohol, isopropanol, defoaming agent are dissolved in boiled water in addition reaction kettle by step 3, are stirred 6 minutes, are then allowed to stand2 minutes；
Step 4 will stir evenly in strong catalyst addition reaction kettle, and the mixture stirred evenly is then poured into ultrasoundWave dispersion machine carries out ultrasonic wave dispersion, ultrasonic power 120-150W, and jitter time is 30-50 minutes, and dispersion temperature is150-160 DEG C, binder is obtained after dispersion.
The catalyst includes following components by weight: 3 parts of benzoyl peroxide, 3 parts of zinc borate, polyacrylamide1.5 parts, 1 part of potassium cyanide and 12 parts of calcium stearate.
The defoaming agent includes following components by weight: 5 parts of nonylphenol polyoxyethylene ether, is gathered 3 parts of tributyl phosphate1.5 parts of acid imide, 2 parts of diphenyl silanediol and 1 part of petroleum sodium sulfonate.
A kind of beneficial effect of the processing method of highly intensified corrugated paper of the present invention is: which increase the resistance to of corrugated paperBroken index and ring crush index improve the service life of corrugated case, meet city so that this corrugated paper has higher intensityField use demand, is conducive to product promotion.
