Description

Non-paper environmental protection dish, sheet material material and manufacture method thereof

The present invention relates to non-paper environmental protection dish, sheet material material and manufacture method thereof.This method is to utilize the organic fiber of natural plants to be moulding material; This organic fiber is blocked with broken diffusing, make it to be irregular and random after the short fiber accumulation of distribution shape, it is dropped in starch heap, stir through abundant, uniform, and cooperate the gelatinization of starch to handle, make organic fiber and gelatinized starch be mixed into the thick shape mixture of glue by geometric ratio or specific multiple proportions; With mould the thick shape mixture of this glue is finalized the design, after being pressed into thing type individualities such as dish, bowl, plate, piece, through super-dry, solidify processing, can make the polymerization of condensing of short fiber and starch, become shape materials such as dish with underlying strength, plate, and this material has the organic substance characteristic of corrodible decomposition, is applicable to make disposable goods and do not influence environmental protection.

General edible dish (as disposable service plate, bowl etc.) or non-edible product (as wallpaper, wallboard etc.), majority is to adopt Poly Foam (expandable polystyrene) material to make the imitative type of various different objects as replacing product traditionally; Because of Poly Foam inexpensive, with after abandon, can avoid disease propagation, thus in the past on the packing of dining room or food the utilization scope very extensive.But Poly Foam because of its rerum natura can't be decomposed through bacterium, and causes continuous accumulation after being dropped in a large number, have a strong impact on the balance of whole ecological, receives common people's concern gradually.Therefore, be raw material with decomposable organic materials, unlikely papery dish, the sheet material material of discarded accumulation for requiring that cause greatly in fashion in recent years, has the trend that replaces above-mentioned Poly Foam material gradually.The papery goods use up abandon after, though decomposable advantage is also arranged, but have following relevant its when making institute indirectly generation have far-reaching, serious, and the shortcoming of very important influence:

One, the employed raw material of papery goods is taken from the tree material, thereby when a large amount of the employing, the felling that certainly will cause forest to be quickened, cause natural, ecological can't balance and and ozone layer will be gradually by the influence of heavy damage, though non-immediately as seen, but, also be quite to be worth common people's worry if do long-range consideration.

Two, paper products are in that to be fabricated onto the process of finishing very complicated by the tree material, and relate to multiple tracks treatment process such as bleaching, well-done, dyeing, and the secondary public hazards that industrial wastewater caused that produced therebetween have to be paid attention to immediately.

Three, according to natural scholar's statistics, forest is because of being subjected to a large amount of felling at present, and the trees quantity that grows up to continued access, at all can't balance, and the forest in the whole world is faced with very fast situation of successively decreasing with loss.It also because of trees quantity reduces fast, gets being difficult for except that the destruction that will cause ecological as the aforementioned and ozone layer, price is surging year by year, causes the cost of paper products also to raise year by year accordingly.At present, the paper products that adopt based on the environmental protection factor in the future certainly will will be surging because of cost, still can be suitable for cooperating hygienic requirements, the advantage that after use it is abandoned because of inexpensive at present and lose it.This point by the trend of wood materials price multiplication over year, is appreciated that paper products can not keep cheap.

The inventor (same applicant) observes and learns above-mentioned situation deeply by experience, thinks that if can replace the tree material with general obsolete material the positive effect of twice laid will be arranged, thereby inspires with non-paper material design the present invention, finishes the present invention through repeatedly testing; The inventor thinks that the present invention is in the benifit industry and benefit and real value is arranged aspect the common people.

The object of the present invention is to provide a kind of non-paper environmental protection dish, it is characterized in that: the disk body obvious strip of tool of mainly drawing materials divides the natural plants of bundle fiber, and through blocking, brokenly loosing and cooperate the gelatinization of starch to handle, by mould shape, the dish that is pressed into.

Another purpose of the present invention is to provide the manufacture method of non-paper environmental protection dish, this method comprises: the organic fiber that natural plants is included blocks and becomes the short fiber shape and do broken diffusing processing, make and be irregular and disorderly after the distribution shape is piled up, fiber with this brachymemma drops in the starch heap again, do abundant, stirring uniformly, and cooperate the gelatinization of starch to handle, make both be mixed into the thick shape mixture of glue by geometric ratio or specific multiple proportions, be pressed into disk body with mould again, through super-dry, processing such as solidify, make the polymerization of condensing of short fiber and starch.

Another object of the present invention is to provide a kind of non-paper sheet material, it is characterized in that: material is mainly taken from the natural plants that the obvious strip of tool divides bundle fiber, through blocking, brokenly loosing and cooperate the gelatinization of starch to handle, and by mould shape, the sheet material that is pressed into.

Still a further object of the present invention is to provide a kind of manufacture method of non-paper sheet material, this method comprises: the organic fiber that natural plants is included blocks and becomes the short fiber shape and do broken diffusing processing, make and be irregular and disorderly after the distribution shape is piled up, fiber with this brachymemma drops in the starch heap again, do abundant, stirring uniformly, and cooperate the gelatinization of starch to handle, make both be mixed into the thick shape mixture of glue by geometric ratio or specific multiple proportions, be pressed into plate with mould again, through super-dry, processing such as solidify, make the polymerization of condensing of short fiber and starch.

Non-paper environmental protection dish provided by the invention, sheet material because of drawing materials from the fiber and the starch of natural plants, all belong to organic substance, abandon with the passing of time also spontaneous corrosion, decomposition, the unlikely eternal accumulation that causes waste material after the use; The special generation that in its manufacture process, does not have secondary pollution sources such as waste water, waste gas, therefore meet environmental protection requirement especially, be suitable as and use up the materials such as edible dish, bowl and lunch box that abandon, or materials such as non-edible wall ornamentation, packing, help the maintenance of global ecological environment.

The making method of non-paper environmental protection dish provided by the invention, sheet material material, just include the natural plants of vertical bar shape fiber because of the condition of drawing materials, therefore can use general discarded plant (as straw, bagasse, herbage etc.), this not only has twice laid and the enthusiasm meaning that digests the part sanitary fill, and draw materials conveniently, with low cost, make made low finished product cost, be suitable as and generally use up the vessel such as health dish, bowl and lunch box that abandon.

Fig. 2-A is the thickness profile key diagram of finished product of the present invention.

Fig. 3 is a finished product shaping operation key diagram of the present invention.

Existing conjunction with figs. describes the present invention in detail.

At first, see also Fig. 1.As shown in the drawing, the flow process of manufacture method of the present invention comprises the following steps:

One, draw materials: material used in the present invention has two kinds, and a kind of is to have the obvious beam splitting of fibre strip in the natural plants, is easy to broken diffusing person; The herbaceous plant of the particularly general low economic value of this plant of drawing materials is as herbage etc.; Or the discarded part after the general crops use, as straw, bagasse etc., its role is to reduce cost of material, and do effective utilization of fibroid waste material, its economic worth of regenerating.Another kind of material then is a general starch.

Two, block: the rectangular fiber of pencil of intercepting natural plants is stem, the leaf section part of beam splitting comparatively obviously, and it is blocked, and makes the segment length who becomes below 50mm.

Three, broken loose: will rub with the hands fast and beat or beat through stem, the leaf part of blocking, and make the slice fiber itemize in its section, and make short fiber be random to, irregular distribution accumulation.

Four, short fiber is dropped in the starch heap and mix, add water then and make starch gelatinization, and continuous stirring makes short fiber mix with starch in the pasty state is full and uniform, and be the thick doughy mix of glue; The practice in this stage also can add water with starch earlier makes it gelatinization, short fiber is dropped in the starch heap again and mixes, and makes the identical processing purpose (being the 1st or the 2nd flow process shown in Figure 1) that reaches the thick doughy mix of glue.Wherein, select for use the reason of starch and natural plant fibre to be based on and approximately contain 20 percent amylose in the general starch; And this amylose very easily produces the effect of mutually combining with natural fiber mixed fashionable, and the fastness of its combination is increased.And the hybrid process in relevant this stage, the mixing ratio of employed short fiber and starch is the thickness of looking the moulding of after-stage finished product, area and the different demands of intensity, and the ratio that configuration mixes, for example geometric ratio (1: 1) or multiple proportions etc.Exemplify and be described as follows:

(1) at the thickness of general edible bowl, dish under the condition of 1-2mm, the ratio that fiber mixes with starch is about geometric ratio.

(2) under the condition of thickness greater than 1-2mm of edible bowl, dish, because of thickness increases, short fiber is made strength support in stratum granulosum degree of dependence reduces, so can lower the consumption of short fiber, the ratio that short fiber is mixed with starch becomes multiple proportions, as the 1(short fiber): 1.5(starch).

(3) under the condition of thickness less than 1-2mm of edible bowl, dish, because of thickness reduces, short fiber is made strength support in stratum granulosum degree of dependence increases, so need to increase the consumption of short fiber, the ratio that starch is mixed with short fiber becomes multiple proportions, as the 1.5(short fiber): 1(starch).

Five, mould shape: doughy mix that this glue is thick drops into the inboard of compacting tool set 2, and repressed typing makes thing types 3 such as the dish that is shaped according to the mould inner mould shape, bowl, plate, piece afterwards (as shown in Figure 3).

Six, the dry processing: it acts on and makes contained water evaporates in starch and the fiber, and the mixture of molded article is solidified, and forms final finished; (following explanation and label are by Fig. 2 at this moment, Fig. 2-A and shown in Figure 3), short fiber 21 is staged an armed rebellion to distribution in 22 layers of inboard of starch, and the polymerization of condensing with it, by the intensity of short fiber 21 cutting back segment bodies and before the adhesive paste of starch 22 is handled, fiber 21 is entangled with mutually because of surperficial pieces when splicing, the net form of the in-plane that forms is in conjunction with tension force, make because of fiber 21 stiffening effects increases, formation is loose by fiber lay down and is distributed, strength support as starch 22 thickness directions, make the dish of making, bowl, thing such as plate or bulk type 3 has the base support power of shaping, can effectively replace similar and other article (as Poly Foam or paper products) unlike material.And according to made thing type 3 apparatus of above-mentioned flow process, one obtaining owing to main fibrous raw material, several twice laids of saying so, price is very cheap, it is simple and easy, quick to add manufacture process, and the processing aspect is few, easy to make, quick, and have inexpensive competitive advantage, can replace traditional made of paper similar product.Again it, the material that includes because of this thing type 3, short fiber 21 and starch 22 are only arranged, both all belong to organic substance, but natural decomposition after abandoning, meeting global environmental protection requirement fully, have enthusiasm meaning and value that actual economic benefit and natural, ecological are safeguarded, really is most important feature of the present invention.

In sum, the present invention has the positive effect of generalization innovation for replacing the innovation of class materials such as traditional Poly Foam or dish made of paper, bowl, various plate, piece, and the material industry is had excellent benefiting.
