Embodiment 1

[0040] A method for filling wood-plastic molding with waste packaging, the specific steps include:

[0041] a. Add the recovered Tetra Pak packaging waste to the agglomerator, the amount of Tetra Pak packaging waste added is 2 / 3 of the internal capacity of the agglomerator; open the agglomerator, so that the agglomerator can break the Tetra Pak packaging waste into Fragments, continue to use the agglomerator to agglomerate the fragments, during which the temperature is controlled at 100~120°C, specifically: when the temperature rises to about 100°C, the rotational speed of the rotating blade of the agglomerator is controlled at 500~700rpm during the stable period, And stop for 30 seconds every working 5 minutes, after continuous treatment for 20 minutes in this way, the pellets of Tetra Pak packaging waste are obtained; the pellets have the following properties: the pellets are a homogeneous mixture, and the pellets can It is a hard non-stick solid when it is hot, and it is a ...

Abstract

The invention discloses a filling wood-plastic forming method for Tetra Pak package wastes, and belongs to the technical field of wood-plastic co-extrusion. The filling wood-plastic forming method forthe Tetra Pak package wastes comprises the following steps: breaking the Tetra Pak package wastes by using a granulator to form aggregates from the Tetra Pak package wastes; carrying out breaking treatment or crushing treatment on the aggregates by using a breaker or a crusher to obtain small particles; adding the small particles and other additives into a main extruder, melting, plasticizing andextruding, extruding a coating structure from a co-extrusion coating section, entering a cooling section of a die, and then extruding from a die orifice of the die to obtain a wood-plastic co-extrusion coated floor. The filling wood-plastic forming method for the Tetra Pak package wastes has the advantages of being simple and feasible, convenient to implement, low in cost, environment-friendly, free of pollution, and the like.

Description

technical field [0001] The invention relates to a molding method for filling wood-plastic with Tetra Pak packaging waste, and belongs to the technical field of wood-plastic co-extrusion. Background technique [0002] Tetra Pak packaging is a series of packaging products for liquid food, a six-layer composite paper packaging composed of paper, aluminum and plastic. In today's society, the demand for Tetra Pak packaging is huge, and a large amount of Tetra Pak packaging waste is generated as a result. In 2016, according to the survey results of relevant departments, the demand for aseptic packaging in China's dairy industry was 110 billion packs, and Tetra Pak had 60 billion packs, accounting for 54.55%. However, the recycling rate of Tetra Pak packaging is only about 0.1%. Some recycled milk cartons and beverage boxes are handed over to paper recycling companies, while plastic and aluminum foil are not fully utilized. More Tetra Pak packaging is treated as garbage or inciner...
