Abstract
The present invention belongs to the field of aluminium-plastic composite material chemical stripping technology, in particular, it relates to a stripper for aluminium-plastics composite film. Said stripper is formed from (by wt%) 7-80% of acetic acid and 93-20% of water, and can be used for making aluminium layer and plastic layer of aluminium-plastics composite material be completely separated off.
Description
Technical field
The invention belongs to the stripper of aluminium plastic composite material chemical stripping technical field, particularly a kind of aluminum-plastic composite membrane.
Background technology
At present, aluminum-plastic composite membrane is widely used in the packing of food, medicine, daily necessities, electronic product etc.In the Production and Packaging of product and use, can produce a large amount of leftover bits and waste, environment is produced have a strong impact on.At present to the treatment process of these wastes be bury, burning or nitric acid, hydrochloric acid, sulfuric acid and so on strong acid erodes the aluminium layer of aluminium plastic composite material and only reclaim plastics.No matter adopt which kind of method, all can produce severe contamination, cause a large amount of wastes of resource simultaneously again environment.
Summary of the invention
The purpose of this invention is to provide a kind of aluminum-plastic composite membrane can being peeled off, both free from environmental pollution, can reclaim aluminium and plastics, the stripper of aluminum-plastic composite membrane free from environmental pollution simultaneously again.
The present invention seeks to realize by following technical proposals.
According to the stripper of aluminum-plastic composite membrane of the present invention, it is characterized in that by acetate and water formulatedly, the weight percent of its prescription is: acetate 7～80%, water 93～20%.
Acetate has another name called acetic acid, is colourless transparent liquid, is slightly acidic.Just contain concentration in the edible vinegar in the life and be 5% acetate, do not report as yet as the stripper of aluminum-plastic composite membrane with acetic acid aqueous solution, acetate and plastics in the stripper of the present invention do not react, and penetrate the oxide compound (Al that plastic layer corrodes the aluminium layer bonding surface
2O
3) layer, the aluminium layer of aluminium plastic composite material is intactly separated to come with plastic layer, this stripper environmentally safe, harmless to being stripped from thing, stripper can be reused, the recyclable utilization of plastics after peeling off and aluminium layer, and stripper does not discharge, evaporateing into airborne acetate and also have certain sterilization, is the method for a kind of environmental protection, safety as stripper with acetate therefore.
Embodiment
The stripper of aluminum-plastic composite membrane of the present invention is characterized in that by acetate and water formulatedly, and its formulation weight per-cent is: acetate 7～80%, water 93～20%.
In concrete enforcement, can select the stripper of different proportionings for use according to desired velocity of separation and appointed condition.
Embodiment 1: the lower concentration stripper
The weight percent of stripper prescription is an acetate 10～20%, water 90～80%.Be mixed with lower stripper, at normal temperatures, aluminum-plastic composite membrane soaked in this stripper 10～14 hours, aluminium layer is peeled off mutually with plastic layer.Under the comparatively high temps about 60 ℃, splitting time can shorten to 3～5 hours.
Embodiment 2: the intermediate concentration stripper.
The weight percent of stripper prescription is an acetate 30～40%, water 70～60%.Splitting time at normal temperatures can shorten to 5～7 hours, and under the temperature about 60 ℃, splitting time can shorten to 0.5～1 hour.
Embodiment 3: the high density stripper.
The weight percent of stripper prescription is an acetate 60～70%, water 40～30%.Evidence, though the acetic acid concentration in peeling off has had large increase, splitting time is not seen obvious shortening; Still need soak under the normal temperature plastic-aluminum is peeled off.At this moment acetate volatilizees in a large number, must be sealed reactor, stimulates otherwise can produce more seriously operator.
Embodiment 4: the stripper of recommendation.
The weight percent of stripper prescription is an acetate 35%, water 65%.Splitting time is about 6 hours under the normal temperature, and under 60 ℃ of temperature, disengaging time then is about half hour.Therefore can be used as industrial recommendation proportioning, can be stirred when closing to an end, separate to promote plastic-aluminum in the immersion process neutralization.
Claims (5)
1, a kind of stripper of aluminum-plastic composite membrane is characterized in that by acetate and water formulatedly, and the weight percent of its prescription is: acetate 7～80%, water 93～20%.
2, the stripper of aluminum-plastic composite membrane according to claim 1 is characterized in that described formulation weight per-cent is acetate 10～20%, water 90～80%.
3, the stripper of aluminum-plastic composite membrane according to claim 1 is characterized in that described formulation weight per-cent is acetate 30～40%, water 70～60%.
4, the stripper of aluminum-plastic composite membrane according to claim 1 is characterized in that described formulation weight per-cent is acetate 60～70%, water 40～30%.
5, the stripper of aluminum-plastic composite membrane according to claim 4 is characterized in that described formulation weight per-cent is acetate 35%, water 65%.
