Abstract
The invention belongs to a method for separating and recycling aluminum and plastics. The method comprises the following steps: taking and washing a waste aluminum-plastic wrappage, and drying the wappage at the temperature of 100 DEG C for 2-4 hours; cutting and weighting the dried aluminum-plastic composite hose, putting the cut dried aluminum-plastic composite hose in a layered trough, adding a composite liberation agent, and stirring at the constant temperature of 30-80 DEG C for 10-30min to separate the aluminum from the plastics, wherein the weight ratio of the aluminum-plastic composite hose to the composite liberation agent is 1:10-80; and recycling the separating agent after separation, cleaning the separated aluminum and the separated plastics, drying the aluminum and the plastics at the temperature of 100 DEG C for 2-4 hours, and respectively obtaining the aluminum and the plastics. The invention takes the waste aluminum-plastic wrappage as the raw material, and recycles the aluminum and the plastics by separating; the method is simple and rapid, the separation is complete, the separation efficiency is high, and the quality is purer; both the obtained aluminum and the plastics have higher recycling values, can be directly or after being modified applied to the fields of decoration, fitting-out, package and the like, have important economic values and meanings of energy saving and emission reduction; and the production process has the advantages of simplicity, small investment and easy popularization.
Description
Technical field
The invention belongs to a kind of method of plastic-aluminum Separation and Recovery.
Background technology
Aluminium scrap is moulded packing through handling, and can reclaim aluminium and plastics, and the aluminium of recovery and plastics can directly or be applied to decoration, finishing and packing etc. after modification, uses more and more extensively, has higher recovery value.Especially industrial aluminium, resource reduces gradually, price increases gradually, if can recycle, will have important economic value and energy-saving and emission-reduction meaning.At present, plastic-aluminum separating method is common has acid to dissolve or alkali molten partition method, weak acid layering partition method and demixing of solvents partition method etc.Utilize aluminium can be dissolved in the principle of soda acid, use the method that acid is dissolved or alkali dissolves to dissolve the aluminium in the material, thereby reclaim plastics, and then aluminum bearing waste is processed aluminium polychloride or aluminum sulfate.This acid is dissolved or the molten partition method of alkali has the halfway shortcoming of recovery.In addition, utilize organic monoacid molecule such as acetic acid, formic acid etc. can permeate plastic layer, and then the oxide of the aluminium of each layer of dissolving bonding and the characteristic that can not dissolve pure aluminum is distinguished complete the separation with the aluminium in the packaging material with plastics.This weak acid layering partition method has the shortcoming that the reaction time is long, separative efficiency is low.In addition, utilize plastics with an organic solvent to be made the plastics swelling, aluminium is peeled off from the plastic-aluminum sheet, recycle respectively then by the character of swellings such as organic solvent such as toluene, chloroform.This demixing of solvents partition method has the shortcoming that solvent consumption is big, toxicity is big, cost is high.
Summary of the invention
The objective of the invention is in order to overcome the recovery that above-mentioned prior art exists not thoroughly, the reaction time is long, and separative efficiency is low; Solvent consumption is big, and cost is high, shortcomings such as not environmental protection; Provide a kind of and can reduce consumption of organic solvent, shorten disengaging time, reduce environmental pollution; Improve working environment, and the hybrid separation agent is reusable, the new method of the plastic-aluminum Separation and Recovery that reduces cost.
For realizing the foregoing invention purpose, the technical scheme that the present invention takes is that the method for this plastic-aluminum Separation and Recovery is: clean oven dry; Shear, weighing adds the hybrid separation agent; Constant temperature stirs, and aluminium lamination and plastic layer are peeled off automatically, reclaims release agent; Clean separating obtained aluminium and plastics, oven dry obtains aluminium and plastics respectively; Specific as follows:
Get aluminium scrap and mould packing material, clean up, oven dry below 100 ℃, 2～4 hours time; Shear the plastic-aluminum combined flexible pipe after drying, weighing places the layering groove, adds the hybrid separation agent, and plastic-aluminum combined flexible pipe and hybrid separation agent are by weight being that 1: 10～80,30～80 ℃ constant temperature stirred 10～30 minutes, and aluminium lamination and plastic layer are peeled off automatically; After separating completion, reclaim release agent, clean separating obtained aluminium and plastics, oven dry, obtains aluminium and plastics respectively at 2～4 hours time below 100 ℃.
Said hybrid separation agent is that 40%～70% organic acid, 10%～20% surfactant and 20%～40% organic solvent are formed by percent by volume.
Said organic acid is formic acid, acetate etc.Said surfactant is polyoxyethylene 20 sorbitan monolaurate, OPEO, NPE etc.Said organic solvent is acetone, ethyl acetate, carrene, chloroform etc.
It is raw material that the present invention moulds packing material with aluminium scrap, comprises various toothpastes such as Colgate-Palmolive toothpaste, Darlie shell, Crest toothpaste etc., and useless flexible pipe for medical purpose and other adopt the plastic-aluminum combined packing material that forms.
It is raw material that the present invention moulds packing material with aluminium scrap, and through separating recyclable aluminium and plastics, method is simply quick; Separate complete; Separative efficiency is high, and quality is purer, and aluminium that is obtained and plastics all have higher recovery value; Can directly or after modification, be applied to decoration, finishing and packing etc., have important economic value and energy-saving and emission-reduction meaning.This production technology is simple, invests for a short time, promotes easily.

Fig. 1 is technological process of production figure of the present invention.
The specific embodiment
Embodiment 1: get useless toothpaste, remove the cap of toothpaste, plastic-aluminum combined flexible pipe is cleaned up, under 100 ℃ temperature, dry; 2～4 hours time, shear the toothpaste composite soft tube after the broken oven dry, take by weighing 20kg and place the layering groove; Add the hybrid separation agent, under 30～80 ℃ of constant temperature, stir and made the plastic-aluminum separation in 10～30 minutes, plastic-aluminum combined flexible pipe and hybrid separation agent are by weight being 1: 50; Said hybrid separation agent is that 50% formic acid, 20% OPEO and 30% chloroform are formed by percent by volume, after separation is accomplished, reclaims release agent; Clean separating obtained aluminium and plastics, oven dry obtains aluminium and plastics respectively.The plastic-aluminum separation reaches 100%, and the aluminium yield is 12%～16%, and the plastics yield is 78%～87%.
Embodiment 2: get useless flexible pipe for medical purpose, remove the cap of flexible pipe for medical purpose, plastic-aluminum combined flexible pipe is cleaned up, under 100 ℃ temperature, dry; 2～4 hours time, shear the plastic-aluminum combined flexible pipe after the broken oven dry, take by weighing 20kg and place the layering groove; Add the hybrid separation agent, under 30～80 ℃ of constant temperature, stir and made the plastic-aluminum separation in 10～30 minutes, plastic-aluminum combined flexible pipe and hybrid separation agent are by weight being 1: 50; Said hybrid separation agent is that 50% formic acid, 20% OPEO and 30% chloroform are formed by percent by volume, after separation is accomplished, reclaims release agent; Clean separating obtained aluminium and plastics, oven dry obtains aluminium and plastics respectively.The plastic-aluminum separation reaches 100%, and the aluminium yield is 14%～16%, and the plastics yield is 80%～82%.
