Description

A kind of environment-friendly degradable paper cup material and preparation method thereof
Technical field
The invention belongs to dixie cup technical fields, and in particular to a kind of environment-friendly degradable paper cup material and preparation method thereof.
Background technique
Disposable paper cup is disposable paper cup in people's daily life in essential articles, especially catering industry Usage amount it is very big, but many disposable paper cups used at present be all it is nondegradable, be easy to cause environmental pollution.With Requirement of the modern society to living environment it is higher and higher, environment it is clean greening neatly have been to be concerned by more and more people, open Hair disposable degradable dixie cup is an effective way for solving plastic pollution.
Currently, common dixie cup is that the body paper made of chemical wood pulp (white board) is machined, covers one layer A kind of paper container obtained by vinyon lamination can disappear in the production process although its is easy to use, low in cost A large amount of timber are consumed, while polyethylene is not also degradable, is unfavorable for ecological, environmental protective.
Summary of the invention
In view of the above-mentioned problems, the present invention is intended to provide one kind with peanut shell, sugarcane skin, Cortex Bulbus Allii etc. for raw material, by one Series processing prepare it is resulting environmental protection, it is degradable, and have antibacterial effect paper cup material, with and preparation method thereof.
The invention is realized by the following technical scheme:
A kind of environment-friendly degradable paper cup material, is made of raw material from the following weight:
Honeysuckle 5-10, cordate houttuynia 3-5, Radix Isatidis 5-15, sodium chloride 3-5, Cortex Bulbus Allii 5-10, onion-skin 4-8, peanut shell 20- 30, sugarcane skin 20-25, pectinase solution 100-150, bleaching agent 5-10, hydroxymethyl cellulose solution 20-50, chitosan 8-10, Lamination slurry 10-60；
The pectinase solution concentration is 10-20%.
Further, preparation method includes the following steps:
(1) honeysuckle, cordate houttuynia, Radix Isatidis are rinsed with clear water, removes epidermis sundries, then wrapped up preservative film and be put into household freezer In, -30 ~ -40 DEG C of freezing 1-2h, being immediately placed in pulverizer after taking-up and being crushed to length is 0.3-0.5cm, its volume is added In 10-20 times of distilled water, sodium chloride is added, is aided with sonification procedure, is heated to boiling, decoct 1-3h in ultrasound, until Volume-diminished is original 1/5-1/4, uses layer 2-4 filtered through gauze after cooling, and squeeze out moisture, obtains Chinese herbal medicine filtrate reservation Spare, filter residue is put into freeze drying box, and -20 ~ -30 DEG C of freeze-dryings obtain the dregs of a decoction；
(2) it after the Cortex Bulbus Allii recycled from food market, onion-skin, peanut shell, sugarcane skin sorting being removed sundries, is soaked with clear water Bubble and flushing, remove the impurity such as the sandy soil on surface, are then immersed in pectinase solution again, be warming up to 40-50 DEG C, with 200- The revolving speed of 300rpm, stirring enzymatic hydrolysis 3-5h, is put into vacuum oven at 80-90 DEG C after filtering, and dry 10-15h is transferred to crushing It carries out being crushed to the particle that partial size is 0.5-2mm in machine；
(3) dregs of a decoction obtained by step (1) and step (2) gains are uniformly mixed, are put into vapor tight tank, then led into vapor tight tank Enter the water vapour containing bleaching agent that temperature is 100-103 DEG C, while the pressure in vapor tight tank is increased into 2-2.2MPa, handles 3- After 5h, then stops steam and be passed through, and slowly bleed off pressure to normal pressure, bleed off pressure used time 3-5min, gains are then subjected to microwave Processing；
(4) step (3) gains are added to progress fiber in beater and discongest 1-3h, it is molten that hydroxymethyl cellulose is then added Liquid, chitosan continue to be beaten 1-2h, and beating consistency 2.9-3.1% is then added into and manufactures paper with pulp into paper machine, shape At body paper；
(5) it after carrying out lamination processing using lamination slurry to body paper obtained by step (4), is transferred in air dry oven, 30-50 DEG C Drying forming.
Further, which is characterized in that step (1) the sonification procedure condition is 50-60Hz, 1200-1500W.
Further, step (3) bleach additive composition is sodium hypochlorite, and content is 5-10% in water vapour.
Further, the preparation method of step (4) described hydroxymethyl cellulose solution is to be added to hydroxymethyl cellulose Chinese herbal medicine filtrate described in step (1) in claim 2, at 50-60 DEG C, with the revolving speed stirring and dissolving 20- of 300-400rpm 30min, it is cooling.
Further, step (5) the lamination slurry is polylactic acid.
Further, the Chinese herbal medicine filtrate is passing through decolorization using preceding, and decolorising agent is active carbon or absorption resin One or both of.
Beneficial effects of the present invention: the present invention is using peanut shell, sugarcane skin, Cortex Bulbus Allii, onion-skin as raw material, simultaneously also Honeysuckle, cordate houttuynia, Radix Isatidis are added to collectively as dixie cup raw material, by crushing, a series of processing, the shape such as are beaten, manufacture paper with pulp At body paper, recycles polylactic acid to carry out lamination as lamination slurry, be prepared for a kind of environment-friendly type dixie cup of good performance, the dixie cup Not only cost of material is low, green non-poisonous, and promotes the recycling of resource, and waste be changed into values on side, while biodegradable, to ring Border is pollution-free, promotes the sustainable development of environment, and on the other hand, the medicinal herb components of addition, which have passed through, to be made full use of, and assigns The performance of dixie cup broad-spectrum antiseptic is drunk water using this dixie cup, also can have certain health-care effect to human body；Medicinal herb components are passed through Crushed immediately after freezing, farthest remain the effective component in Chinese herbal medicine, avoid its in crushing process due to It is infected with and causes damages, while carrying out papermaking using the dregs of a decoction, medical fluid is beaten, forms making full use of for resource, also guarantee The high efficiency of dixie cup antibacterial；Stifling bleaching is carried out to raw material after bleaching agent solution is flashed to steam, original can be fully infiltrated into Material is internal, improves the effect and efficiency of bleaching.
