Abstract
The invention discloses disposable tableware capable of being completely degraded. The disposable tableware is prepared from the following substances in part by weight: 70 to 80 parts of starch, 0.5 to 1 part of sucrose ester, 8 to 10 parts of vegetable fibers, 3 to 5 parts of polybutylene succinate, 6 to 8 parts of talcum powder, 0.5 to 0.8 parts of red halloysite, 4 to 6 parts of agar and 2 to 3 parts of glycerinum. The disposable tableware has good glossiness, and is good in temperature resistance, fire resistance, acid resistance and pick resistance, capable of being completely degraded, low in cost, good in performance and good in popularization value.
Description
Technical field
The invention belongs to tableware and manufacture field, particularly relate to a kind of disposable tableware that can be degradable.
Background technology
Phase early 1980s, the fast pace of the modern life and people's craving for health care, the developed country such as the U.S., Japan has widely used disposable polystyrene foamed plastics tableware, soon produced again the more cheap polypropylene of price and polyethylene foams tableware, these tablewares receive the welcome of catering trade and human consumer greatly.Undeniable, the reflection of the development of tableware and evolution process to be the process of scientific and technological level and civilization degree be scientific and technological level and civilization degree is the mark that the progress of Materials science and health care level improve.
Can in recent years, because a large amount of waste or used plastics film, plastics bag and disposable non-degradable tableware usage quantity are increased sharply, and abandon arbitrarily, each big and medium-sized cities all generally define serious white pollution.Its same vehicle exhaust, have phosphorus washing composition be listed in together this year Environmental Protection in China administer three large emphasis.Plastics are the very unmanageable domestic refuses of one, it is mixed into soil can affect Crop moisture and nutriment, cause crop production reduction, landfill gets up, land occupation and upper a century just can be degraded, and easy to be agglomerating bundled, and it even can read to fill in current, cause water conservancy projects, urban facilities fault, lead to disaster.
Present people have abandoned traditional pure plastics disposable product, it is improved, usual interpolation some be easy to degrade material composition, though make moderate progress to a certain extent, can not be degradable, still pollute to some extent environment, people have also invented and can make disposable tableware by degradable material with starch, stationery etc. for this reason, but all generally have that intensity is low, poor heat resistance, chemical industry additive is many, cost is high shortcoming.
Summary of the invention
In order to solve the problem, the invention provides a kind of disposable tableware that can be degradable, have that cost is low, performance good, free of contamination feature.
The present invention is realized by following technical scheme:
Disposable tableware that can be degradable, be made up of the material of following weight part:
70 ~ 80 parts of starch, 0.5 ~ 1 part of sucrose ester, 8 ~ 10 parts of vegetable fibres, 3 ~ 5 parts of poly butylene succinates, 6 ~ 8 parts of talcum powder, 0.5 ~ 0.8 part of Red Halloysite, 4 ~ 6 parts of agar, 2 ~ 3 parts of glycerine;
Its preparation method is:
(1) put into high-speed mixing stirrer by after 70 ~ 80 parts of starch, 0.5 ~ 1 part of sucrose ester mixing, control rotating speed is 300 ~ 350rpm, stirs 10 ~ 15min;
(2) 8 ~ 10 parts of vegetable fibres, 3 ~ 5 parts of poly butylene succinates, 6 ~ 8 parts of talcum powder, 0.5 ~ 0.8 part of Red Halloysite, 4 ~ 6 parts of agar, 2 ~ 3 parts of glycerine are joined in high-speed mixing stirrer, control rotating speed is 400 ~ 450rpm, and it is for subsequent use that stirring 15 ~ 20min obtains compound;
(3) send in heat pressing forming machines by compound, control pressure is 8 ~ 10MPa, and extrusion temperature is 140 ~ 150 DEG C, takes out to obtain work in-process after shaping 25 ~ 30s;
(4) work in-process dried, get product after germicidal treatment.
Further, described starch be W-Gum, tapioca (flour), konjak starch, Rhizoma Dioscoreae starch one or more form with arbitrary proportion proportioning.
Further, described vegetable fibre by rice straw, wheat stalk, vegetables bar stem, bagasse, reed rod one or more with arbitrary proportion proportioning extract form.
Further, first with coated infrared drier double finished product drying during step (4) process, then with ultraviolet to its sterilization.
Further, described disposable tableware can be processed to bowl-type, dish, spoon and chopsticks.
The present invention has following beneficial effect: the present invention's composition used all can degradable environmentally safe, and main component is starch and vegetable fibre, not only draws materials convenient and cheap; The sucrose ester added has hydrophilic and lipophilic group simultaneously, can enter in the leptospira structure of starch granules, be combined form stable complex compound with amylose starch, suppress the crystallization of starch molecule, delay the aging of starch, improve heat resisting temperature and the viscosity of starch simultaneously, improve molding effect; Poly butylene succinate is odorless tasteless, easily by the enzyme decomposition in natural multiple-microorganism or animal and plant body, metabolism, being finally decomposed into carbonic acid gas and water, is typical fully biodegradable polymer materials, the thermotolerance of tableware can be improved, its density and mechanical property can be improved again; Talcum powder and Red Halloysite can improve glossiness, heatproof, fire-resistant, the antiacid and pick resistance of tableware, and contained mineral element can be absorbed by the body, and can improve body immunity, and Red Halloysite also has certain bacteriostatic action, promote the security of tableware; Gained finished product tableware can be completely degraded, and cost is low, and performance is good, has good promotional value.The mechanical properties such as disposable tableware intensity provided by the invention, toughness and security all reach industry requirement, and tableware of the present invention can be degraded for 2 months under outdoor natural condition, can not produce white pollution.
