Abstract
A reclaiming method for discards includes such steps as classifying recovered discards, mechanically breaking off the classified discards, proportionally loading the discards into mould, heating while pressurizing for a certain time until the thermoplastic substance in the discards is in molten state, and quickly cooling to fixate its shape.
Description
The present invention is relevant with the processing of waste material, particularly about a kind of useless processing method that material utilizes again of filling.As everyone knows, the surrounding enviroment of people life have multiple not tractable waste material, and plastic bag has for example added the rubber waste product of sulphur, EVA foaming thing waste material, and PE foaming thing waste material, PU foaming thing waste material, discarded carpet, and thermosetting resin waste material etc. all is.Up to now, mostly handled for these waste materials to bury or to burn, only bury the essence that to destroy soil, burning then can be deposited reluctant carbon slag by stream, more and the resulting result of these processing methods these waste materials are disappeared, and can't form new material and be used.
In order to give utilization again to waste material, the thunder holder of Holland stranding part Co., Ltd more once proposed a kind of method for treatment of waste material and China Taiwan Province grant a patent (this reference of No. 80107480 patent case patent announcement of annex one shadow), though this processing method can obtain some solid waste and utilize, still can isolate the liquid waste and the residue that can't utilize again.
In addition, the U.S. bud green global resources limited company also once proposed a kind ofly to prepare the solid waste processing method of useful products and similarly get permission patent (this reference of No. 83107501 patent case patent announcement of annex two shadow), this method most important characteristic is that solid waste is divided into different density currents, and the different density of foundation is collected utilization again, though also can be to waste material again to utilize with the method, but it need rely on suitable cost and complex equipment to implement, and more and similarly it also can residually have the material that can't utilize again.
Therefore, main purpose of the present invention is promptly in the processing method that provides a kind of waste material to utilize again, and it not only can be made and can supply the material of utilization again, and unserviceable material can residually not arranged.
The processing method that provides a kind of waste material to utilize again is provided, and the material that utilizes again that it is made has the characteristic of composite.
A further object of the present invention be provide a kind of waste material again with the processing method of electricity, its process is easy and must complex apparatus can not implement.
For reaching aforesaid purpose, waste material provided by the present invention utilizes processing method at first the waste material that reclaims to be classified again; Inferior aforementioned classified waste utilization machinery is subtracted amasss into broken object; Once more for taking aforementioned all kinds of broken object according to certain ratio and it being imported in a molding tool; Then be that the thermoplasticity thing is molten condition to making wherein enough to this one scheduled time of mold heated then, and in heating, pressurizeed; For being cooled to rapidly, the material in this mould makes its typing below the room temperature at last; Wherein between first two steps are rapid, has the step that a pair of waste material is cleaned and dries; Wherein the size of all kinds of broken objects is between 3mm-10mm; Wherein second step makes its some things in pelletized form when forming broken object, and another partly is fibrous; Wherein to take all kinds of broken objects be to be the best with following ratio to third step:
Plastic cement shot-like particle: rubber shot-like particle: fibrous material=wherein in plastic cement shot-like particle include thermoplasticity shot-like particle at 5: 3: 2, and thermosetting shot-like particle; Wherein the ratio of thermoplasticity shot-like particle and thermosetting shot-like particle is 4: 1; Wherein the heating-up temperature of the 4th step is 160 degree Celsius-220 degree Celsius; Wherein the condition cooled off rapidly of the 5th step is temperature 10 degree Celsius-15 degree Celsius, 1 minute-5 minutes time.
Below lifting a preferred embodiment of the present invention now is described further.This embodiment recycles the waste material and makes the useful material of system again with following step process:
1. thing foams the waste material that reclaims such as EAV, PE, PU, damaged tire, thermoplasticity, thermosetting plastic goods waste material, and discarded carpet etc. is distinguished into thermoplastic plastic, thermosetting plastic and rubber three major types, it also can optionally give thinner classification certainly;
2. aforementioned classified waste material is cleaned and dried, in order to remove greasy dirt or foreign material;
3. will subtract with these waste materials of machinery knives and amass into two partly, wherein a part cuts into the following shot-like particle of 3mm, and another partly then cuts into following fibrous (or flocculence) thing of 10mm;
4. subtract waste material after long-pending according to the plastic cement shot-like particle with aforementioned: the rubber shot-like particle: the ratio of fibrous material=5: 3: 2 is mixed and is imported in the rectangle die cavity of a mould, wherein this plastic cement shot-like particle can be 100% thermoplasticity shot-like particle, or according to thermoplastic plastic's shot-like particle: the ratio of thermosetting plastic shot-like particle=4: 1;
5. with heating equipment this mold heated extremely Celsius at least 160 is spent, the kind adjustment of the visual waste material of this heating-up temperature, for example also may be up to 220 degree Celsius, in heating, the thing grain in the die cavity is bestowed the pressure of 50kg/cm-100kg/cm with oil pressure unit, the time of this pressurized, heated carried out one minute at least, so in the case, but the material of meeting the heat melting will melt and evenly flow and form parent phase (Matrix) because of the heating pressurization, and the fiberous material that can't melt, granular foamed materials etc. then form the Rankine that is surrounded by parent phase, in other words, waste material will form a kind of new composite in this step;
6. last, again the material in this mould is cooled off rapidly, it can be finalized the design according to the shape of die cavity, the type of cooling of this step can be direct water-cooling, or import in the set circulatory system of mould with cooling water, generally speaking Leng Que temperature was preferably in and took the photograph formula 10-15 degree then according to the volume of cooled object and thermal conductivity coefficient and decide cool time, and the time then is more than one minute below five minutes.
By aforesaid treatment step as can be known, the present invention has following advantage at least:
A. the present invention can recycle waste material completely.
B. the made again material processed of the present invention contains fiber and therefore an amount of plastic cement not only has suitable Hardness and the elasticity of degree more and have intensity as the composite, are quite wide with its range of application, For example it can be used to make the head of footwear boots, the footwear of the footwear boots such as specific use such as mountain-climbing, football, baseball Pad, and the articles for daily use such as mat applying, tea cup mat, RECYCLE BIN, flowerpot, carpet, floor.
C. do not add any chemical agent or solvent in the processing procedure of the present invention, therefore can not make Become the secondary public hazards.
D. equipment of the present invention is simple, and processing cost is cheap.
