Description
Technical field：
The present invention relates to corrugated paper processing technique fields, and in particular to a kind of work using waste paper and coconut palm chaff processing corrugated paper
Skill.
Background technology：
Corrugated case is as a kind of excellent packaging material, because it is with light, resistance to puncture, shockproof, easy processing shaping etc.
Mechanical performance and good decoration printing adaptability, can cycling and reutilization, it is environmentally safe the advantages that, therefore be subject to existing
The favor of generation society.Use scope is more and more wider, and development speed is also getting faster.At present, corrugated paper is mostly made of waste paper, realizes
The reasonable recycling of waste paper, but waste paper resources are still limited, can not fundamentally reduce the consumption problem of timber.
Coconut palm chaff is cocoanut husk fiber dust, is coconut by-product or discarded object after processing, is from cocoanut husk fiber
A kind of pure natural organic matter medium under coming off in process.Coconut palm chaff after through processing, which is very suitable for cultivating, plants
Object is horticultural media popular at present.
In order to use coconut palm chaff, we develop a kind of profit on Research foundation for many years in the new opplication of corrugated paper manufacture field
With the technique of waste paper and coconut palm chaff processing corrugated paper, by the dosage for adding to reduce waste paper of coconut palm chaff, and made corrugated paper is expired
Foot routine packing instructions, while recycling again can also be carried out.
The content of the invention：
The technical problems to be solved by the invention be to provide it is a kind of can ensure on the basis of waste paper dosage is reduced it is made
Corrugated paper meets the technique using waste paper and coconut palm chaff processing corrugated paper of conventional packing instructions.
The technical problems to be solved by the invention are realized using following technical solution：
A kind of technique using waste paper and coconut palm chaff processing corrugated paper includes the following steps：
(1) coconut palm chaff is dehydrated：Coconut palm chaff is placed in 55~65 DEG C of baking ovens constant temperature to be dehydrated, make coconut palm chaff water content be down to 3wt% with
Under, and the coconut palm chaff powder of 60-80 mesh is made through pulverizer；
(2) slurrying：The waste paper powder of 80-100 mesh is made through pulverizer for waste paper, then waste paper powder is added in beater, and to
Water is injected in beater, uniform paper pulp is made through being fully beaten, then adds in coconut palm chaff powder and plant amylum, continues mashing and is made equal
Body is homogenized, gained slurry is added in fiberizer, not broken slurry is ground through fiberizer, most goes to remove the gred through scummer afterwards
Material；
(3) it is dehydrated：Made slurry is pumped to wet end shaping dehydration and reaches 15-25% to mass dryness fraction, the slurry after shaping is defeated
It send to press section to be dehydrated to mass dryness fraction and reaches 40-50%；
(4) dry：Slurry after squeezing is delivered to drying portion, is dried to mass dryness fraction and reaches 90-95% to get finished product corrugation
Paper.
The mass ratio of the waste paper powder, coconut palm chaff powder and plant amylum is 10-15:1-5:0.1-0.5.
The one kind of the plant amylum in cornstarch, wheaten starch, potato starch, starch from sweet potato, rice starch.
The power of motor of the beater is 1.1kW, rotating speed 1400r/min.
The power of motor of the fiberizer is 1.5kW, rotating speed 1480r/min.
The pressure of the press section is 800kN/m.
Modified coconut palm chaff powder is made in the modified processing of coconut palm chaff powder, and method of modifying is：Self-crosslinking is added in into coconut palm chaff powder
Acrylic resin and trihydroxymethylpropanyltri diglycidyl ether, and 120~130 DEG C of guarantors are heated to the heating rate of 5 DEG C/min
Temperature 2~4h of stirring, then adds in hydrolysis of polymaleic anhydride and sulfurized lard, continue at 120~130 DEG C insulated and stirred 0.5~
1h, gained mixture are cooled to -10~-5 DEG C of heat preservations with the cooling rate of 5 DEG C/min and stand 3~5h, be most made afterwards through pulverizer
60-80 mesh powders are to get modified coconut palm chaff powder.
The coconut palm chaff powder, self-crosslinking acrylic resin, trihydroxymethylpropanyltri diglycidyl ether, hydrolysis of polymaleic anhydride and
The mass ratio of sulfurized lard is 100:5-10:1-5:0.5-3:0.5-3.
The preparation method of the self-crosslinking acrylic resin is：First ethoxylated dodecyl alcohol is dissolved in deionized water,
And 50~60 DEG C of insulated and stirreds are heated to, N hydroxymethyl acrylamide, zinc methacrylate and Diacetone Acrylamide are added,
50~60 DEG C of 20~35min of insulated and stirred are continued at, then add in 10wt% persulfate aqueous solutions, are heated to reflux state guarantor
The medicinal extract of 15~25wt% of water content is made through being concentrated under reduced pressure for temperature 2~5h of stirring, gained mixture, and gained medicinal extract naturally cools to
It is sent at less than 35 DEG C in freeze drier, micro mist is made to get self-crosslinking acrylic through micronizer in dry obtained solid
Resin.
The ethoxylated dodecyl alcohol, deionized water, N hydroxymethyl acrylamide, zinc methacrylate, diacetone third
Acrylamide, the mass ratio of 10wt% persulfate aqueous solutions are 0.5-2:30-50:1-5:5-10:0.5-2:1-5.
The present invention using its distinctive net structure and is assisted using above-mentioned made self-crosslinking acrylic resin as main modifying agent
With auxiliary modifying agent trihydroxymethylpropanyltri diglycidyl ether, hydrolysis of polymaleic anhydride and sulfurized lard to significantly improve coconut palm chaff and paper
Interface compatibility between powder promotes coconut palm chaff and paper powder in water homodisperse to form even slurry, is used reducing paper powder
Ensure the mechanical property of made corrugated paper while amount.
The beneficial effects of the invention are as follows：
(1) present invention is reduced the dosage of the waste paper in corrugation paper conversion, and is realized using coconut palm chaff powder as major auxiliary burden
Coconut palm chaff makes the application field of coconut palm chaff be no longer limited to horticultural media in the new opplication of corrugated paper manufacture field；
(2) it is used for paper processing that corrugation is made using waste paper powder, coconut palm chaff powder and plant amylum by two step pulp making operations in the present invention
Even slurry, and corrugated paper is made through subsequent normal operation, made corrugated paper has the bag to compare favourably with current conventional corrugated paper
Performance is filled, can be widely applied for the packaging of multiple product.
