Abstract
The invention discloses an aluminum-plastic separation soaking penetrant for a waste toothpaste aluminum plastic packing material and a using process thereof. The invention is characterized in that: the soaking penetrant is prepared from 20 to 30 mass parts of 93 percent industrial sulfuric acid, 10 to 20 mass parts of sodium formate and 2 to 5 mass parts of fatty alcohol-polyoxyethylene ether, and is added into 100 mass parts of water to form soak solution; the waste toothpaste aluminum plastic packing material is soaked in the soak solution; and the soaked composite material is fished out, an aluminum material and a plastic material are separated, and the soak solution is washed away with clear water. The recycle benefit of the toothpaste aluminum plastic packing material is improved; the quality and grade of the separated polyvinyl plastic and aluminum are improved; and the cost performance of the aluminum and the plastic recycled by the invention is high, the market demand is high, and the environmental pollution is greatly reduced.
Description
Technical field
The present invention relates to a kind of aluminum-plastic separation soaking penetrant for waste toothpaste aluminum plastic packing material and use technique.
Background technology
At present, all can there be the generation of waste materials of the aluminum-plastic packaged material of millions of tons every year in China.Toothpaste is the commodity of commonly using, and its packing also is aluminium plastic composite material.Add up according to authoritative department: the weight of the aluminium plastic composite packaging of 350 gram weight toothpaste is about 17 grams, if a three-person household is used 350 gram weight toothpaste per month, can calculate the Chinese waste toothpaste aluminium plastic composite packaging that produces per month about 5000～5500 tons.Plastic-aluminum combined discarded object can not carry out regeneration and granulation as plastics simply, more can't work as the aluminium waste recovery and smelt.Particularly there is part toothpaste in the toothpaste aluminium plastic composite packaging in the packing, has strengthened the difficulty of recycling, and many salvage collections department rejects this type of discarded object.The aluminum-plastic packaged discarded object of tradition toothpaste is mostly used the processing methods such as simple landfill, burning, cracking, generation is harmful in a large number, the shortcoming of noxious material, during the aluminum-plastic packaged MAT'L recycling of traditional toothpaste of while, aluminium, mould be difficult to separate, shortcoming that the rate of departure is slow, also there is the shortcoming that volatility is high, effectiveness is low, cost is high in the immersion bleeding agent of the use of the aluminum-plastic packaged MAT'L recycling of traditional toothpaste.
Summary of the invention
The purpose of this invention is to provide in a kind of recycling process and do not produce any industrial pollution, improve the aluminum-plastic packaged aluminium-plastic separating process of toothpaste of the aluminum-plastic packaged MAT'L recycling benefit of toothpaste and a kind of efficient, environmental protection, the excellent aluminum-plastic separation of valency soaks bleeding agent.
The technical solution used in the present invention is: a kind of aluminum-plastic separation soaking penetrant for waste toothpaste aluminum plastic packing material, it is characterized in that: industrial sulphuric acid, sodium formate, AEO by 93% concentration mix, and described each constituent mass is such as lower: 20-30 parts of the industrial sulphuric acids of 93% concentration, 10-20 parts of sodium formates, 2-5 parts of AEOs.
The use technique of described aluminum-plastic separation soaking penetrant for waste toothpaste aluminum plastic packing material is: with concentration be 93% industrial sulphuric acid, sodium formate, AEO in mass ratio the ratio of 20-30 parts in sulfuric acid, 10-20 parts of sodium formates, 2-5 parts of AEOs be made into the immersion bleeding agent, add in 100 parts of water and be made into soak, the aluminum-plastic packaged material of waste toothpaste is put into soak to be soaked, temperature is controlled at 30 ℃～40 ℃, through 1～4 hour, be warmed up to 50 ℃～70 ℃, insulation 30min.Then the composite plastic after will soaking is pulled out, with aluminium, mould bi-material separately, with clear water soak is rinsed well.
The present invention will carry out the aluminum-plastic packaged waste material of toothpaste behind the treatment steps such as sorting, cleaning, fragmentation and put into the present invention and soak bleeding agent and soak and separate, when having overcome the aluminum-plastic packaged MAT'L recycling of traditional toothpaste, aluminium, mould be difficult to separate, shortcoming that the rate of departure is slow, improved the aluminum-plastic packaged MAT'L recycling benefit of toothpaste; The quality, the class that have improved vinyon behind the aluminum-plastic separation and aluminium are higher; Overcome traditional shortcoming that immersion bleeding agent volatility is high, effectiveness is low, cost is high.The aluminium and the plastics cost performance that reclaim with the present invention are high, and the market demand is wide, and has greatly reduced the pollution of environment.
The specific embodiment
The present invention is further illustrated below in conjunction with specific embodiment:
Embodiment 1:
In the reactor with agitating device, the aluminum-plastic packaged broken material of toothpaste that add fragmentation of 3kg, cleaned adds 5kg water, 1.25kg sulfuric acid, 0.75kg sodium formate, 0.18kg AEO respectively again, evenly mixes.First temperature is controlled at 30 ℃～40 ℃, soaked 1～4 hour; Then be warmed up to 50 ℃～70 ℃, insulation 30min.Plastics, aluminium are taken out respectively, rinse rear drying well with clear water.The quality of weighing plastics (polyethylene) is behind bone dry: 2.5kg, the quality of aluminium is: 0.3 kg.
Embodiment 2～5, undertaken by the process of embodiment 1, and its concrete data see Table 1
