Description
Technical field
The present invention relates to a kind of goods that can degrade fully and manufacture method thereof, more specifically, relate to a kind of product and manufacture method thereof that can degrade fully, that make by sponge.
Background technology
Along with the continuous development of global process of industrialization, environmental pollution has become very important major issue, and wherein troubling with so-called white pollution especially.Disposable plastics (comprising the plastics cutlery box, utensil, wrapping material of foaming and thin plastics bag, film, agricultural mulching etc.) are after it uses, owing to lack the value of recycling, wherein the overwhelming majority is discarded in the environment, mainly concentrate on around the Scenic Spot Area, in river course and road both sides, farmland, lake and the pool, and each corner in cities and towns, this has not only destroyed view, caused " visual pollution ", and in nature, be difficult to degraded because it has, natural ecological environment has also been caused directly and collateral damage.Recently discover, it with polystyrene PS residual a certain amount of styrene monomer in the plastics cutlery box of disposable foaming of raw material, this is harmful to HUMAN HEALTH, developed countries has limited the use of PS plastics in food product pack, or require coating processing is carried out on its surface, and China still uses this type of plastics mess-tin at present in a large number.
And on the other hand, many natural plant fibre raw materials such as bamboo powder, wood powder, bagasse, powdered rice hulls, reed slag and wheat bran etc. are generally all burnt as refuse or are abandoned serious environment pollution; Or as fertilizer sources or feed, utility value is lower.How to realize utilization of waste material and reduce environmental pollution, become the difficult problem that the environmentalist must solve.
Summary of the invention
The present invention is devoted to utilization of waste material and reduces environmental pollution, and a kind of plant fiber material product that can degrade fully is provided.
These article comprise the component of following content (weight percent): vegetable fibre powder 40-80%, tackiness agent 2-40%, releasing agent 5-15%, starch 5-40%.Preferably, these goods also contain the toner of 0.1-2% (weight).
In an embodiment of the invention, described vegetable fibre powder is selected from one or more in bamboo powder, wood powder, bagasse, powdered rice hulls, reed slag and the wheat bran.Described tackiness agent is selected from polyvinyl alcohol and polycaprolactone.In another embodiment, described tackiness agent is selected from one or more in poly-propyl methocel (HPMC), Resins, epoxy, aminoresin and the resol.
In another embodiment of the present invention, described releasing agent is selected from Zinic stearas and calcium stearate.Described starch is native starch or treated starch.Described toner is selected from the chromium toner; The cadmium toner; The iron toner; The cobalt toner; Titanium dioxide; Prussian blue; Carbon black; Phthalein green grass or young crops; The quinacridone toner, red as quinacridone magenta and quinacridone; The azo toner is as organic yellow, dual-azo yellow, permanent yellow, permanent bordeaux and naphthol red; Aniline black dyestuffs is as spirit black SB, nigrosine base and nigrosine BW; Oil blue; The toner Huang; Toner indigo plant; In the red and alkali blue of toner one or more.
Goods of the present invention can for tableware, film material, section bar, flowers with basin or alms bowl, or other suitable daily living article.
Preferably, the granularity of described vegetable fibre powder is the 40-100 order.
Another aspect of the present invention provides the manufacture method of this goods, and it may further comprise the steps:
(1) take by weighing each component respectively after, at 60-80 ℃ of dry 1-5 hour, to remove moisture content;
(2) with grinding machine each component is pulverized, so that each component uniform mixing;
(3) the gained mixture be will grind and corresponding heat pressing forming machines, presswork put into;
(4) the moulding product polishing is extremely smooth.
According to the actual needs of the goods of being produced, described step also can comprise the disinfectant step, and preferably, this sterilisation step by finishing with the uviolizing finished product in 30-60 minute.
The present inventor is based on for many years practical experience, utilize plant fiber material to produce the biological products that to degrade fully, this technology can make full use of various natural plant fibre raw materials, when reducing environmental pollution, also improved the use value of raw material, the goods fully biodegradable of being produced and be nontoxic, and manufacturing cost is lower, the finished product type is various, is fit to very much daily life and uses.The present invention makes each component have excellent processing fluidity from change the form of vegetable fibre in essence with structure.The goods of producing can reach relevant international testing standard technically, as the U.S./European food testing standard.
In addition, tackiness agent used in the present invention is divided into two kinds, and a kind of is degradable, as polyvinyl alcohol and polycaprolactone; Another kind cannot be degraded, as poly-propyl methocel, Resins, epoxy, aminoresin and resol.In process of producing product, adopt the performance of the product that different tackiness agents obtains also inequality.If use degradable tackiness agent, behind the product abandonment, in physical environment, begin the bacterium of mildewing in general 1-2 month, degradable 60-70% after 3 months, but such product is disposable, can not reuse, can not be by the test of microwave oven or dishwasher.And if use nondegradable tackiness agent, then in manufacture course of products, add starch, it can destroy the molecular chain of tackiness agent, buries when product in the soil that contains bacterium, can be become and argillous size by bacterial degradation, until decomposition.Generally speaking, in physical environment, begin the bacterium of mildewing after six months, degradable 60-70% after a year.Though the degraded required time is longer relatively, the product of producing like this can be reused, can be by dishwasher and microwave oven test.
