Abstract
The invention relates to a preparation method for magnetic plastic particles. The preparation method comprises the following steps: feeding waste plastics into a clean water pond and pouring a mixed solution; taking out the waste plastics, drying the waste plastics, and inputting the waste plastics in a plastic crusher to be crushed; putting the crushed waste plastics, ground calcium carbonate andan organic solvent into the plastic granulator, adding the softened waste plastics into a reaction kettle, then adding a magnetism-increasing auxiliary material, wherein the proportion of the magnetism-increasing auxiliary material and the waste plastics is 1: 23, and keeping the temperature and insulating the mixture for 1-3 hours; and mixing the auxiliary material with the stirred mixture in the reaction kettle in a reinforced manner, melting and blending the mixture through a twin-screw extruder, and carrying out extrusion and granulation. By blending the magnetic material into the waste plastics, the plastics have certain magnetism for adsorbing metal particles underwater. Compared with a magnet, the cost is low, rust is not generated, and the magnetic plastic particles are light. Meanwhile, the magnetic materials adsorb each other to enhance the cohesiveness, so that the tensile strength is enhanced.
Description
Technical field: [0001] The invention relates to the field of plastic processing, in particular to a method for preparing magnetic plastic particles. Background technique: [0002] Plastic particles are roughly divided into more than 200 types, and there are thousands of types of subdivisions. There are dozens of common types, general-purpose plastics, engineering plastics, and special plastics. General plastics: polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, polyurethane, etc. Engineering plastics: nylon, polytetrafluoroethylene, polyoxymethylene, polycarbon silicone, etc. Special plastics: thermosetting plastics, functional polymer plastics, such as artificial kidneys. [0003] Most of the existing plastic particles start from the toughness and strength. The design process improves the strength through the combination of compounds. There is no one that adds magnetic materials to increase the internal links, thereby enhancing the strength of pla...
