Abstract

The invention relates to an environment-friendly novel method for recycling and processing magnetic plastic from waste plastic. The magnetic plastic is prepared from the following raw materials in percentage by weight: 40 percent of the waste plastic, 40 percent of carbonyl iron powder, 15 percent of nano-tourmaline powder and 5 percent of plastic additives. The waste plastic is polyethylene and the plastic additives comprise a coupling agent and a plasticizer; the iron carbonyl powder is ferrite carbonyl iron powder or rare-earth permanent carbonyl iron powder. The magnetic plastic provided by the invention is mainly used for magnet therapy cushion products, is low in cot and has a magnet therapy health-care effect.

Description

technical field [0001] The invention relates to plastics, in particular to an environmentally friendly new method for recycling and processing magnetic plastics from waste plastics. Background technique [0002] Composite magnetic plastics are mainly composed of resin and carbonyl iron powder, the resin plays a role in bonding, and carbonyl iron powder is the source of magnetism. Composite magnetic plastics can be divided into two categories according to their magnetic properties: one is that the directions of easy magnetization of magnetic particles are arranged in a disorderly manner, which is called isotropic magnetic plastics, and its performance is low. Barium ferrite is usually used as a magnetic material. . The other type is to arrange the easy magnetization directions of carbonyl iron powder in sequence by applying an external magnetic field or mechanical force during processing, which is called anisotropic magnetic plastics, and strontium ferrite magnetic plastics ...
