Description

A kind of disposable degradable paper disc and preparation method thereof
Technical field
The present invention relates to disposable paper disc processing technique field more particularly to a kind of disposable degradable paper disc and its preparations Method.
Background technique
With the development of modern science and technology, rhythm of life is getting faster, and people require life simple and efficient, disposable to produce Product enter people's lives, and paper disc has the advantages that convenient, healthy, and very big convenience is brought to our daily life.At present A large amount of disposable plate is made of plastics, and the situation of China's up to the present white pollution has seriously threatened people Daily life.Disposable plate made of previous used plastic material herein, can not adapt to current social development, And since it has that degradation is difficult, also being abandoned by market slowly now.Therefore, the good paper of degradability is developed Disk is just particularly important.
Summary of the invention
Based on background technique there are the problem of, the invention proposes a kind of disposable degradable paper disc and preparation method thereof, Waterproof of the present invention, oil resistivity are good, and have excellent degradability.
The invention proposes a kind of disposable degradable paper discs, the film layer including disk body and coated in disk body inner surface, The disk body includes following raw material: 25-35 parts of bamboo fibre, 18-25 parts of hemp stalk fiber, 20-30 parts of sugarcane fiber, corn 35-55 parts of starch, condensation polysaccharide 15-25 parts, 5-10 parts of sodium alginate, 5-10 parts of chitosan, 170-190 parts of pure water;
The film layer be by be coated on disk body inner surface be combined into film liquid it is dry after the film that is formed.
Preferably, it is described be combined into film liquid the preparation method comprises the following steps: cationic starch is uniformly mixed with deionized water, then Under stirring conditions, it is warming up to 90-95 DEG C, is gelatinized 20-25min, it is standby that the gelatinization of starch solution that concentration is 5-10wt% is made With;
Polyvinylalcohol solids powder is added in deionized water, is then heated to 92-96 DEG C, stirring to abundant dissolution, system The poly-vinyl alcohol solution that concentration is 5-7wt% is obtained, it is spare;
Guar gum is added in deionized water, is then heated to 92-96 DEG C, stirring to abundant dissolution, it is 1- that concentration, which is made, The guar gum solution of 2wt%, it is spare;
Gelatinization of starch solution, poly-vinyl alcohol solution, guar gum solution are added in container, stirred evenly, standing and defoaming, It obtains being combined into film liquid.
Preferably, gelatinization of starch solution, poly-vinyl alcohol solution, guar gum solution volume ratio be 40-60:20-35:15- 30。
Preferably, being combined into film liquid coating thickness is 0.03-0.05mm.
Preferably, the invention also discloses the preparation method of the paper disc, include the following steps:
S1, bamboo fibre, hemp stalk fiber, sugarcane fiber are mixed, then acetic acid solution immersion treatment, is washed with clear water later Only, it dries, crushes, obtain composite fibre powder;
S2, condensation polysaccharide, sodium alginate, chitosan are added in pure water and are stirred evenly, then water-bath is kept the temperature, and is obtained Mix adhesive;
S3, composite fibre powder, mixing adhesive, cornstarch are added in batch mixer and are uniformly mixed, obtain mixture, Then moulding press is fed the mixture into, it is hot-forming to get disk body;
S4, film liquid will be combined into be uniformly coated on disk body inner surface, then freeze-day with constant temperature, it is cooling after to get disposable Degradable paper disc.
Preferably, S1 concrete operations are as follows: bamboo fibre, hemp stalk fiber, sugarcane fiber are mixed, are then 10- with concentration The acetic acid solution immersion treatment 3-4h of 17wt% is cleaned with clear water later, is dried, and is crushed, is obtained composite fibre powder.
Preferably, in S2, bath temperature is 92-97 DEG C, and water-bath soaking time is 15-25min.
Preferably, in S3, hot pressing temperature is 150-165 DEG C, hot pressing time 3-5min.
Preferably, in S4, at 75-85 DEG C, the time is controlled in 1.5-3.5h for temperature control when freeze-day with constant temperature.
After the present invention mixes bamboo fibre, hemp stalk fiber, sugarcane fiber, with acetic acid solution immersion treatment, it is fine that mixing is made Powder is tieed up, fiber can remove the harmful toxic matter of fiber surface after acetic acid solution immersion treatment, while can also remove part half The ingredients such as cellulose, siliceous, make the cross-linked structure on its surface by partial destruction, to reduce fiber surface contact angle, change Kind fiber wetness, allows fiber preferably in conjunction with auxiliary agent, improves processing performance, and then improve the stability of paper disc;And Bamboo fibre, hemp stalk fiber, sugarcane fiber, which are used cooperatively, has the effect of enhancing paper disc hardness, and discarded rear degradable.The present invention Condensation polysaccharide, sodium alginate, chitosan are added in pure water by a certain percentage, compounding obtains mixing adhesive, the mixing Adhesive is more environmentally-friendly, degradable and safe and non-toxic compared to traditional Organic adhesive.Cationic starch is added the present invention In deionized water, heating gelatinization is configured to certain density gelatinization of starch solution, then by gelatinization of starch solution and polyvinyl alcohol Solution, guar gum solution compound by a certain percentage, are made and are combined into film liquid, polyvinyl alcohol, guar gum make to make with compounding for starch The viscosity for being combined into film liquid obtained is significantly improved compared to common starch solution, will be combined into film liquid and is applied in disk body inner surface Cloth can generate uniformly and the film layer of densification in disk body inner surface after drying, can play barrier action to grease and water, Jin Erji The earth improves paper disc waterproof oil resistance.Degradability laboratory test results show, disposable degradable paper prepared by the present invention The weightlessness that the weightlessness that disk soil buries 30 days is more than 18%, soil buries 60 days is more than that the weightlessness buried 120 days of 40%, soil is more than 84%, is shown It writes and is higher than commercially available common disposable degradable paper disc, it is seen then that degradability of the present invention is excellent.In short, waterproof of the present invention, oil resistivity It is good, and there is excellent degradability.
