Embodiment 1

[0015] A method for preparing antistatic functional materials from aluminum-plastic composite waste, the process flow is: aluminum-plastic composite waste—cleaning—crushing—sieving—agglomeration—aluminum powder, additives—extrusion—semi-finished product—extrusion—finished product, the method The specific steps are as follows:

[0016] (1) Cleaning: The recycled aluminum-plastic composite waste was washed repeatedly with water for 5 times until there was no oil stain. In order to speed up the decontamination, 5% NaOH solution was used for cleaning, and the recycled materials were dried naturally after cleaning. Adopt plastic cleaning machine to clean in the example, purchased from Zhangjiagang City Xinke Machinery Co., Ltd.;

[0017] (2) Crushing and sieving: The cleaned and dried recycled materials are crushed into granules with a pulverizer, screened with a 10-mesh sieve, washed once with water and dried. The pulverizer is purchased from Shandong Tongjia Machinery;

Abstract

The invention discloses a method for preparing an antistatic functional material by using aluminum-plastic composite wastes. The method comprises the following steps: cleaning the aluminum-plastic composite wastes, crushing, sieving, granulating, adding aluminum powder and assistants, extruding to form a semi-finished product, and extruding to obtain a finished product, wherein technologic conditions of the granulating step are characterized in that 0.8L of 95DEG C water is sprayed, the charging time is 3min, the air exhaust time is 5min, the crushing time is 10min, and 15kg of the wastes is processed every time; and technologic conditions of the extrusion step are characterized in that the extrusion temperature is 180-200DEG C, and the extrusion pressure is 20-35MPa. The method for preparing the antistatic functional material has the advantages of simple operation process, low raw material cost, high economic benefit and good social benefit.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to the technical field of recycling waste materials, in particular to a method for preparing antistatic functional materials by using aluminum-plastic composite waste materials. Background technique [0002] Under the background of the country's advocacy of circular economy, the recycling of aluminum-plastic composite packaging waste has become a hot spot of "turning waste into treasure" by environmental protection departments and investors in recent years. Waste aluminum-plastic composite film is a large category of aluminum-plastic composite waste. At present, common aluminum-plastic composite films include BOPP / aluminum, PE / aluminum, etc., which are mainly used for various food packaging. The actual use of aluminum-plastic composite flexible packaging bags is It is a kind of mixed waste, which is difficult to recycle. The treatment method abroad is mainly incine...
