At present, as the demand for beverages and dairy products increases, the amount of composite packages composed of 75% paperboard, 20% Low Density Polyethylene (LDPE) and 5% aluminum also increases dramatically. The recycling of these packages has become an urgent problem. At present, the recycling technology of the packaging box mainly comprises 3 types: hydraulic regenerated pulp technology, plastic-wood technology and color-music board technology.
1) Hydraulic regenerated pulp technology. Separating paper pulp from the packaging box to produce corrugated boards, paper towels, paper boxes and the like; the plastic and aluminum components in the packaging box are extruded into granules, which become good raw materials for producing plastic and aluminum products.
2) And (3) plastic wood technology. The packaging box contains high-quality paper fibers and plastics, and the paper fibers and the plastics are crushed and extruded to produce low-cost, attractive and durable plastic-wood products, such as roof tiles, protective plates for automobiles, office furniture plates and the like. Meanwhile, the material is also a good raw material for indoor furniture, outdoor gardening facilities and industrial trays.
3) And (4) a color board technology. Directly crushing the waste packaging boxes, and performing hot pressing treatment to prepare the colorful plate. The colorful board can be made into various products, such as advertisement signboard, litterbin and other urban facilities, which is beautiful and durable and has low cost.
The invention provides a method for preparing an HDPE modified aluminum-plastic composite reclaimed material. The aluminum-plastic composite reclaimed material, HDPE and other additives are uniformly mixed by adopting a method of mixing, crushing, extruding, granulating and injection molding by using a dried open mill, and are plasticized by an extruder, uniformly mixed and granulated, and then molded in an injection molding machine to obtain the high-strength aluminum-plastic composite material. The HDPE modified aluminum-plastic composite reclaimed material prepared by the invention has excellent mechanical properties.
Problems to be solved by the invention
The material used in the invention is an aluminum-plastic composite material of the beverage packaging box after paper fibers are removed, and the difficulty of raw material treatment is increased due to a series of problems of high humidity, irregular shape and the like of the raw materials. Because the modulus and tensile strength of LDPE in the regrind are low. Therefore, if a preparation process which is simple and can greatly improve the physical and mechanical properties of the reclaimed materials can be found, the application field of the aluminum-plastic composite reclaimed materials can be further widened. The invention provides an aluminum-plastic composite material with high mechanical property.
