Problems solved by technology

The aluminum-plastic and aluminum-plastic paper packaging materials that are separated and recovered with strong acid have obvious defects: 1) the use of strong acid may lead to unsafe operation; 2) strong acid will cause environmental pollution
The current hydraulic separation technology also has defects such as low economic benefit and incomplete recovery.

Abstract

The invention relates to an environment-friend dissociation technique for recovering plastic-aluminum and plastic-aluminum paper package materials. The invention comprises a, mixing the materials of following mass ratio into a mixture organic solvent which contains 60-70% organic alcohol, 10-15% organic ester, 5-8% organic hydrocarbon, 10-15% organic ether and 1-3% organic phenol, b, immerging recovered plastic-aluminum and plastic-aluminum paper package materials into the mixture organic solvent which can submerge the recovered plastic-aluminum and plastic-aluminum paper package materials, c, immerging the recovered plastic-aluminum and plastic-aluminum paper package materials for 6-12h, while aluminum and plastic, or aluminum, plastic and paper can automatically separate, taking out aluminum, plastic and paper, classifying and packing. The invention has the advantages of safe operation, non environment pollution, low cost and high recovery rate.

Description

technical field [0001] The invention relates to a method for controlling environmental pollution and waste utilization, in particular to an environment-friendly decomposition technology for recycling aluminum-plastic and aluminum-plastic paper packaging materials. Background technique [0002] With the improvement of our country's national economy, technological level, and people's living standards, aluminum-plastic and aluminum-plastic paper packaging materials are widely used. Aluminum-plastic packaging materials (composited by aluminum foil and plastic) are most commonly used in pharmaceutical factories Tablet packaging and the leftover scraps of the packaged tablets, etc. Aluminum-plastic paper packaging materials (made of aluminum foil, wood pulp paper, polyethylene plastic hot-pressed or high-frequency composite), the most common are milk cartons (Tetra Pak), beverage boxes, etc. These packaging materials are not easy to separate naturally, so A huge amount of non-deg...
