Abstract

The invention relates to a formula and a method for producing wood-plastic composite material from waste polyethylene cables. Such raw materials as waste polyethylent cable particles, pure polyvinyl chloride powder, wood powder, a metallic soap stabilizer, a coupling agent, chlorinated polyethylene and methacrylic acid polyesters and a lubricator are added into and mixed in a high speed mixer according to the formula, and the mixing temperature is 100 to 110 DEG C, the mixing time is 20 to 35 min; the well mixed material is added into an extruder for extrusion, the rotating speed of the mainframe of the extruder is 40 to 60r / min, the rotating speed of a feeding machine is 4 to 6r / min, and the materials are shaped after being extruded. The polyvinyl chloride raw material adopted by the method of the invention is the peels of waste cables dismantled by domestic enterprises undertaking the dismantling of waste cables, and is cheap and helpful for environmental protection; most of the plastic auxiliary agents adopted by the method are non-toxic products or products of low toxicity, which are of little harm to human body and the environment during material production and using process.

Description

technical field [0001] The invention relates to the recycling and utilization of waste plastics, in particular to a formula and a method for producing wood-plastic composite materials by using waste polyvinyl chloride cable materials. Background technique [0002] In the research on the preparation of wood-plastic composite materials, the polyvinyl chloride used is basically commercial-grade pure material, and some recycled materials are also scraps or some quality waste that appear in the production of polyvinyl chloride products. Better transparent polyvinyl chloride products have a higher cost. And utilize the waste and old polyvinyl chloride cable material of low price to produce wood-plastic material, also do not see the report. [0003] As the sheath of wires and cables, cable materials are exposed to the natural environment all the year round, subjected to sun exposure, rain erosion, seawater immersion, acid and alkali corrosion, and erosion of metal elements and bac...
