This embodiment is identical by the condition of plant material powder by heating and pressurizing and compressed moulding and previous embodiment.
Below, the manufacturing process of container 1 is described with reference to Fig. 3.
This manufacture method is to be made of following operation: will be that the plant material of principal constituent is pulverized the plant material powder form and pulverized the natural decomposition raw material powder that forms by the tackiness agent of natural decomposition material and mix making mixing raw material powder equably with the husk; Then, aforementioned mixing raw material powder is made the container compressed moulding by the pressurizing device heating and pressurizing.At first, preparing (preparation) mainly is the plant material (step 20) that contains husk, and the plant material prepared is ground into the size (step 21) of 50～300 meshes, making plant material powder (step 22) with pulverizer etc.In addition, prepare the tackiness agent (step 23) of natural decomposition material, the natural decomposition material prepared is ground into the size (step 24) of 50～300 meshes with pulverizer etc., make natural decomposition raw material powder (step 25).
Then, the plant material powder is cooperated with given ratio with the natural decomposition tackiness agent, mix equably with agitator etc. and make mixing material 7 (step 26).At this moment, the mixing material of mixing raw material powder keeps characteristics in order to have good shape, and wherein the raw material powder of the plant material powder of husk and tackiness agent cooperates ratio by the tackiness agent of 60～90% plant material and 10～40%, preferably 65～85% plant material and 15～35% tackiness agent constitute.In addition, this manufacture method is, with mixing raw material powder heating and pressurizing and the occasion of compressed moulding according to making the raw material that the mixing raw material powder is selected, can be made with the mud that adds specified rate moisture.At this moment, according to the moisture amount of selected material, self-evidently also can adopt the material that needn't add moisture.
On the other hand, prepare non-woven fabrics 8 (step 27) by weaving cotton cloth of forming of natural decomposition material and/or lamination.Therefore, shown in Fig. 4 (A), will weave cotton cloth and/or the non-woven fabrics 8 of lamination for example is configured on the bed die 3.Shown in Fig. 4 (B), weave cotton cloth and/or the non-woven fabrics 8 of lamination on be coated with the mud of blended mixing material 7 equably, then, with respect to being coated with weaving cotton cloth and/or the non-woven fabrics 8 of lamination and drive pressurizing device 5 of mixing material 7, applied load P, the extrusion forming by pressurization make sheet material 9 dry solidifications (step 28) of extrusion forming on mold 2.Then, the mixing material 7 that constitutes by plant material and rosin at exsiccant sheet material 9 superimposed layers, it is configured on the bed die 3, make well heater 4 energisings that are provided with respect to mold 2 and bed die 3, drive pressurizing device 5 simultaneously, applied load P ground moulding (step 29) on mold 2 by heating and pressurizing, thus natural decomposition containers 1 (step 30) made.
In the rosiny occasion of using as the natural decomposition material of tackiness agent, because the rosiny thermotolerance is low, melt the prolongation of molding time in order to prevent it, can control clamping time and mold temperature by controller 6.
By controller 6 can be with mold temperature, for example the Heating temperature with the mold 2 of mould is set in 160～170 ℃, the Heating temperature of the bed die 3 of mould is set in 150～160 ℃.In this embodiment, the temperature of mold 2 is set than the height of bed die 3, but with the moulding of mixing material heating and pressurizing the time,, therefore be that the moulding product on bed die 3 may be incomplete in this embodiment because the incomplete phenomenon of moulding product takes place on the mould of low temperature side.When the temperature of mold 2 and bed die 3 is set in below 150 ℃, mutual bonding reaction between the husk particle that is caused by rosin will lag behind, thereby cause the phenomenon that molding time prolongs, the associativity variation of husk has the bad possibility of moulding product simultaneously.When the temperature of mold 2 and bed die 3 is set in more than 170 ℃, even the pyrogenic phenomenon of moulding product also can take place a little growth of molding time.Therefore, if molding time is the degree about 30 seconds, mold temperature 150～170 ℃ temperature preferably then.
And forming pressure is preferably 10～80kg/cm fastening with the mold temperature of mould and the pass of molding time
2Degree.And the thickness of the container 1 that is formed by the extrusion forming of mixing material 7 can adopt various designs, is the thickness more than the 0.5mm but be preferably formed as, and mechanical characteristics such as the intensity of container 1, shape maintenance is better like this.
In addition, therefore plant materials such as husk can use the composition identical with the material of above-mentioned composition owing to be to constitute the additive that forms container, and it has natural decomposition, for reducing cost, can adopt 60～90%, preferably 65～85% content.
6 explanations are about another embodiment of the manufacturing process of the container of the manufacture method of this natural decomposition containers with reference to the accompanying drawings.
This embodiment is identical with the manufacturing process up to step 26 of the foregoing description, therefore saves its explanation here.By step 26 the plant material powder is cooperated, is mixed into mixing material equably by agitator with given ratio with the natural decomposition tackiness agent, with this mixing material heating and pressurizing moulding, formed body (step 31) in the middle of producing.On the other hand, prepare non-woven fabrics 8 (step 32) by weaving cotton cloth of constituting of natural decomposition material and/or lamination.Then, for example as illustrated in fig. 5, middle formed body is configured on the bed die 3, configuration is weaved cotton cloth and/or the non-woven fabrics of lamination and make formed body on middle formed body.Then, switch on the well heater 4 on the bed die 3 to being arranged on mold 2, drive pressurizing device 5 simultaneously, with respect to middle formed body and weave cotton cloth and/or the non-woven fabrics applied load P of lamination, the heating and pressurizing moulding (step 33) by heating and pressurizing, thus produce natural decomposition containers 1 (step 34).
Other embodiment of the manufacture method of natural decomposition containers is described below with reference to Fig. 7～10.
The manufacture method of this natural decomposition material compositions is, as shown in Figure 7, prepare at least by husk pulverize the vegetable fibre powder that forms, tackiness agent, as the shellac powder and/or the shellac solution of water tolerance and thermotolerance material and be used to improve water-proof natural decomposition paraffin (step 41～43), it cooperated with given amount and produce blended mud (sposh) 14 (steps 46).In this case, can in mud 14, add titanium oxide as reodorant and bleaching disinfectant, and as the lime carbonate (step 44,45) of additive.On the other hand, prepare the sheet material (step 47) of weaving cotton cloth and/or constituting by non-woven fabrics by tabular (stratiform) that the natural decomposition material constitutes.Be impregnated into sheet material in the mud 14 or on sheet material winding-up mud wait and be coated with (step 48), produce the flaggy parts 11 (step 49) that sheet material are impregnated with natural decomposition material mud 14.Then, make flaggy parts 11 dryings (step 50), lamination one deck or two-layer above exsiccant flaggy parts 11 (steps 51).Then, with the flaggy parts 11 of lamination with given shape heating and pressurizing moulding (step 52), thereby produce given natural decomposition containers 18 (step 53).
And, for the lamination procedure of flaggy parts 11, shown in the C of Figure 10, packing material 19 can be got involved aptly thermal insulation, thermotolerance, thickness and the intensity of adjusting container 18 between the flaggy parts 11.Packing material 19 can be weaved cotton cloth and/or raw mineral materials such as natural decomposition material such as non-woven fabrics or lime carbonate, calcium hydroxide, calcium oxide, titanium oxide, mica powder is made by for example vegetable fibre powdered material, stratiform.
The condition of flaggy parts 11 compressed mouldings by heating and pressurizing is along with the water ratio of the cooperation ratio of material and material and different, and for example, Heating temperature is set in 100～250 ℃, moulding pressure and is set in 30～200kg/cm
2And molding time is set in the scope between 3～60 seconds, and, also can similarly set with the foregoing description.
The mud 14 that is made of mixing material is to mix by the material fiting ratio example of listing below to make: 40～90% vegetable fibre powdered material, 5～40% shellac solution adhesive, 1～30% titanium oxide deodorizing bleaching disinfectant, 1～40% natural decomposition paraffin, 1～20% lime carbonate and as the water of nubbin.
The vegetable fibre powder is made of the pulverized powder that is ground into 50～350 mesh size.And, can in husk, add selected material from vegetable material such as bamboo, sugarcane, straw, coconut coke, bagasse, wood chip, staple bits, Bombay fiber crops (the annual grass that careless section rose of Sharon plant belongs to), paper pulp and two or more mixing material thereof.This plant material preferably adopts pulverizes the powder form, but according to the purposes of container 18, also can adopt the degree of grinding of coarse state.
