Problems solved by technology

[0013] In addition, after mixing and crushing various plastic parts of scrapped cars, various materials are mixed together, such as materials mixed with PP, ABS, PVC, and PC. The performance of various plastics is quite different, and it is difficult to mix and remanufacture. The added value of remanufacturing is low, the scope of industrial application is narrow, and the feasibility of mixed recycling and remanufacturing methods is low

Abstract

The invention belongs to the field of recycling of waste plastics of scraped automobiles, and relates to a method for recycling thermoplastic polypropylene plastic parts of a scraped automobile. The method comprises the following steps of: manually disassembling nonmetallic inner and outer ornaments and structural parts of the scraped automobile, manually sorting thermosetting plastic parts and thermoplastic plastic parts, further manually sorting the thermoplastic polypropylene plastic parts, manually disassembling and separating metallic linkage parts, circuits and the like of the sorted thermoplastic polypropylene plastic parts, performing two-stage crushing on the polypropylene plastic parts, performing ferromagnetic sorting on two crushed materials respectively to separate out metallic scraps, separating out fine metallic scraps and metallic paint by using a roller direct-current high-voltage corona and electrostatic composite electric field sorter, performing sampling performance detection on the cleaned and dried materials, adding a modifier according to the detection results and the using requirements, granulating, and manufacturing automobile plastic members by using the materials. By using the method, the plastic recycling problem of the scraped automobile is solved, broken plastic resources of the scraped automobile are recycled, environmental pollution is avoided, the energy consumption is low, and the additional value is high.

Description

technical field [0001] The invention belongs to the field of recycling and remanufacturing of waste plastics from scrapped automobiles, and relates to a method for remanufacturing plastics required by automobile components through a series of processes by utilizing waste plastic parts of scrapped automobiles. Background technique [0002] With the improvement of people's awareness of environmental protection, it is required to recycle scrapped automobile materials, especially scrapped automobile waste plastics that pollute the environment. The "Automotive Product Recycling Technology Policy" issued in 2006 requires the establishment of a classified collection and sorting system for scrapped automotive materials and substances, and a complete recycling, processing, and utilization system for automotive renewable resources. The goal of the first stage: from 2010, the recycling rate of all domestic and imported M2 and M3, N2 and N3 vehicles should reach about 85%, and the recyc...
