Abstract
The present invention relates to a kind of method of from aluminium plastic composite material, extracting aluminium.By the aluminium plastic composite material fragment is mixed the back pyroprocessing with organic solvent, make dissolving plastic in the aluminium plastic composite material in organic solvent, the last again aluminium foil that reclaims the pulverizing forms aluminium powder and is used.This method rate of recovery height, production efficiency height.
Description
Technical field
The present invention relates to a kind of method of from aluminium plastic composite material, extracting aluminium.
Background technology
Plastic-aluminum, aluminium paper compound package material be owing to have excellent performance and be widely used, and all have significantly every year and increase progressively.Application Areas relates to the packing and decorating of industries such as food, medicine, tobacco, advertisement, chemical industry, and modern architecture material such as al-plastics composite pipe.But when the aluminium plastic composite material consumption increases substantially, the aluminium plastic composite material leftover bits and the waste that produce in production and the life also increase with surprising rapidity, because aluminium and plastics all are the materials that is difficult to degrade, if do not handled, these waste materials and waste meeting long-term existence also cause serious environmental to pollute.Though aluminium and plastics all are can be by the material of processing second stage employ, aluminium is in the same place with plastic hybrid in aluminium plastic composite material, brings difficulty to regeneration.Plastics in the aluminium plastic composite material can be burnt by the method for burning, stay wherein nonflammable aluminium, but the waste gas that so produces has caused new environmental pollution, the high temperature that produces when burning simultaneously also can bring difficulty to regeneration with aluminaization.
Summary of the invention
The purpose of this invention is to provide a kind of efficient height, the method for from aluminium plastic composite material, extracting aluminium simple to operation.
For achieving the above object, the present invention adopts following technical scheme:
The method of extracting aluminium from aluminium plastic composite material of the present invention is characterized in that comprising the steps:
A) with the particle of aluminium plastic composite material and separating agent according to 15: put into heating tank after ratio of weight and number (1-8) mixes and heat;
B) controlled temperature is opened the vertical valve of heating tank at 100 ℃-400 ℃, will reclaim after the condensation of separating agent steam introducing cooling tower;
C) when the separating agent in the heating tank all volatilizees, no longer include condensed separating agent in the cooling tower when flowing out, stop, to be cooledly extract being taken out during to normal temperature the heating tank heating.
After above-mentioned steps C takes out extract, with pulverizer extract is pulverized again, sieve, remove Powdered impurity wherein, leave and take wherein granular aluminium powder.
Above-mentioned separating agent be water and organic solvent according to 1: the mixed product of ratio of weight and number (0.5-1.5).
Above-mentioned separating agent is become to be grouped into by following ratio of weight and number:
Water 1000
Organic solvent 500-1500
Soda ash 5-15.
Above-mentioned separating agent be water and kerosene according to 1: the mixed product of ratio of weight and number (0.5-1.5).
Above-mentioned separating agent is become to be grouped into by following ratio of weight and number:
Water 1000
Kerosene 500-1500
Soda ash 5-15.
After adopting such scheme, heat by heating tank, plastics in the aluminium plastic composite material can be by organic solvent dissolution, stay undissolved aluminium and small amount of impurities, the later recovery that is condensed again of organic solvent volatilization, the yield of aluminium is higher in the production process, and the aluminium in the aluminium plastic composite material can all extract, dissolving plastic wherein is in organic solvent, and what can be used as other industry closes matter oil.
Embodiment
Embodiment 1:
Put in the heating tank after the fragment, water, kerosene of getting aluminium-plastic composite paper mixes according to 15: 2: 2 ratio of weight and number and heat, when treating that temperature reaches 260 ℃, controlled temperature, make it be stabilized in 260 ℃, open the vertical valve of heating tank simultaneously, reclaim after steam is introduced the cooling tower condensation, because the fragment proportion of aluminium-plastic composite paper is bigger, heating tank can reach 260 ℃ under normal pressure, guaranteed that promptly production safety has reduced production cost again; When the water in the heating tank with kerosene all volatilizees, no longer include condensed oil in the cooling tower when flowing out, stop the heating tank heating, to be cooledly extract is taken out during to normal temperature.
This moment, the main component of extract was an aluminium, was Powdered surface attached to aluminium foil after having the plastics additive that is insoluble to kerosene on a small quantity to be heated.With pulverizer aluminium foil is pulverized again, sieved, remove Powdered impurity wherein, leave and take the wherein bigger aluminium powder of particle.Owing to lost sticking power after the heating, the plastics additive powder can nature comes off in crushing process, as long as handle a little or sieve and it can be removed.
What condensed oil can be used as other industry from cooling tower closes matter oil.What present embodiment finally can be obtained the aluminium powder of about 3 weight parts and 5 weight parts closes matter oil, and economic benefit and social benefit are considerable.
