Description
[affiliated technical field]
The present invention relates to a kind ofly have the plastic prod that can constantly discharge fragrance, and this plastic prod itself is simultaneously with environmentally-friendly plastic product constituent and manufacture method thereof antibiotic, that compostable does not cause secondary environmental pollution.
[background technology]
The waste of existing plastics is difficult for by microbiological degradation in physical environment or landfill, rots, and can produce a large amount of dense smokes and toxic gas again in the burning incineration course, causes various environmental pollutions such as air, soil.
The plastic containers manufacture method of existing tool fragrance is finished by following sequence of steps usually; 1. the ultra micron pore hole plastics thing with the same structure body of open cell hole impregnated in the essence, makes it to absorb saturated after soaking, and becomes fragrant master batch.2. mix with the oily family of aggregating into of same structure body plastics and mix the fragrant master batch uniform mixing of stating, penetrate batching, place Jet forming machine then, have the plastic containers of fragrance with ejaculation to finish.
Though aforementioned manufacture method can make the plastic containers of making have automatically scentetd benefit, has following deficiency: the activity duration that is subject to material absorption essence in the manufacturing processed is longer, so that improvement place for the treatment of that output can't effectively promote is arranged; In addition, ultra micron pore hole plastics thing is immersed in the essence process for a long time, essence can produce volatilization by nature, and, the plastics thing is sucked essence to state of saturation when ultra micron pore hole, if move into another manufacturing operation flow process will be in fact the time, then the essence in this plastics materials also can be in volatile flow disalignment constantly, justing think, these cause former material to consume fast and waste virtually, are the high shortcoming of Material Cost.
In view of this, the contriver knows very well the shortcoming place of above-mentioned manufacture method through being engaged in the experience of this industry for many years, is be absorbed in whole-heartedly to drop into research and development, is adhering to not slack spirit, develops the innovative technology of this case all the time, and proposes patent application.

Macromolecular thermoplastic polymer elastomer resin 12 (High Molecule Polymer Resin) can adopt thermoplasticity ion cross linkage fluoropolymer resin (lonomer), or ethene one octene or a type alkene polymeric copolymer elastomer.Adopt macromolecular thermoplastic polymer elastomer resin, not only in the course of processing, can bring into play and other speciality that composition Combination is good, ductility is high, after being made into products in kind, have more the recyclable benefit of system again, in addition, not toxigenicity gas can directly be buried, be burned to finished product itself, burning the back all is that ash is most, can not produce burnt shape residue, tool nontoxicity and non-pollution can not cause secondary pollution person to environment.
3. in the environmental protection polymerization grain composition of the present invention, by using macromolecular thermoplastic polymer elastomer resin, can reach 50% more than effectively with the percentage composition increase of the fine powder of natural plant wood, to reduce the plastics usage quantity, reach the essence effect of cost cutting.
Couplant 13 comprises: 1～5% coupling molecule 131 and 1～5% lubrication prescription 132, coupling molecule can be vinyltriethoxysilane or vinyltrimethoxy silane or metatitanic acid fat wherein any.The add-on of coupling molecule after a little while, bad dispersibility, but add when too much increases cost.Lubrication prescription helps out, can be Zinic stearas or calcium stearate or Magnesium Stearate, oxidized polyethlene wax any.
Adopt above-mentioned material to form, be extruded into the roomy little environmental protection polymerization fine particulate in footpath at 2～3 millimeters (mm) through adding hot milling.
This fragrant master batch 20 comprises environmental protection polymerization grain 10 and heat-resisting natural essence material 21 compositions, and its weight percent is: 20～50% environmental protection polymerization grains, 10,0.05～6% heat-resisting natural essence material 21, homogeneous heating stirs and forms.Wherein, this heat-resisting natural essence material 21 adopts oiliness or wax or the not volatile spices of mealiness tool, also can be Nai Miyin or how rice zinc oxide how the rice titanium oxide or how the rice magnetic wherein any one or more mix or etc. the material of characteristic replace it.When essence material add-on is very few, the one, adsorptivity is poor, and the 2nd, there is not fragrance.But when essence material add-on is too much, the one, the cost height, the 2nd, the fragrance overrich should not adopt.
20～80% plastic raw materialss 30 can be polyethylene (PE), new LDPE (film grade) (LDPE), linear low density polyethylene (LLDPE), high density polyethylene(HDPE) (HDPE), polypropylene (PP), polystyrene (PS), acrylonitrile-butadiene-phenylethylene (ABS) multipolymer wherein any, select plastic raw materials for use according to product rerum natura demand.
In view of the above, above-mentioned composition divides the environmentally-friendly plastic that constitutes, and can carry out modes such as extrusion molding or ejection formation, makes all kinds of plastics 40.
Further, put off until some time later the manufacture method of a kind of environmental protection plastic products of bright the present invention, its work flow is as described below:
Step 1: the kneader temperature is located between 100～130 degree Celsius, earlier the macromolecular thermoplastic polymer elastomer resin 12 of weight percent 5～30% was mediated 5～15 minutes, after making it uniformly softening, add 25～95% ultra tiny powder natural mineral matter 111 (lime carbonate) again, 1～30% ultra tiny powder natural plant starch 112,1～75% ultra tiny powder natural phant fine powder 113 of wood and 1～50% ultra tiny powder binchotan powder 114,1～5% coupling molecule 113,1～5% lubrication prescription 132 continued mixer kneader after 5～15 minutes, send into mixing the extruding of screw extruder and make environmental protection aggregated particles shape, this particle diameter is set in 2～3 millimeters (mm), with as first group of masterbatch; Wherein, aforementioned temperature of carrying out the screw extruder of mixing extruding pelletization is set between 100～180 degree Celsius to best, in addition, the screw extruder can be single-screw extruder or double-screw type extruder, again to adopt two spiral shell formula extruders to be fabricated to the best.
Step 2: the heat-resisting natural essence material 21 of above-mentioned first group of masterbatch being got 20～50% environmental protection polymerization grain 10 and 0.05～6% is with 30～70 degree heated and stirred to 1～5 Celsius hour, as second group of fragrant masterbatch 20; Wherein, the setting range of aforementioned Heating temperature is adjusted Heating temperature according to the anti-burning-point of various spices; And the time of heated and stirred then decides on the quantity number of first group of masterbatch;
Step 3: manufacture environmental protection sizing material goods 40 with extrusion molding or injection molding method, its percentage composition comprises: behind 1～50% the first masterbatch and environmental protection polymerization grain 10,1～50% the second group fragrant masterbatch 20 and 20～80% plastic raw materialss, 30 uniform mixing, make all kinds of tool antibacterial and deodourings, can grow timeliness and discharge fragrance, eliminate the environmentally-friendly plastic finished product of peculiar smell to reach deodorizing with 120～220 degree Celsius (optimum temps is set at 170 degree) extrusion or ejection formation.This environmentally-friendly plastic finished product can be various refuse bag, shopping bag, clothing storage bag, bathing cap, raincoat, air-permeable envelope, tNonwovens, textile fibres, toy, furniture daily necessities plastic prod, automobile inside plate, electronic peripheral product, foaming product etc.
