Embodiment 1

[0024] The magnetic paint that is conducive to environmental protection recycling includes: particles with soft magnetic properties, binder solution, water, and the weight ratio range of each component is as follows:

[0025] Granules with soft magnetic properties 1kg

[0026] Binder solution 0.5kg

[0027] Appropriate amount of water

[0028] The particle size of the particles with soft magnetic properties is below 0.5 micron. Generally, the mass ratio of the binder solution to the soft magnetic particles is about 0.4-0.6.

[0029] In this embodiment, the particles with soft magnetic properties are reduced iron particles, and the anti-oxidation layer is anti-oxidation paint. Particles with soft magnetic properties can also choose ferrite soft magnetic particles. Since ferrite has stable performance, it is not necessary to apply an anti-oxidation layer. The binder solution is made of Shanghai Jinshan Petrochemical PVA grade 1799 binder 80% with Shanghai Jinshan Petrochemic...

Abstract

The invention relates to magnetic coating materials beneficial to environment-friendly recycle, belonging to the technical field of environment protection, and comprising the following components: particles with soft-magnetic characteristics, bonding agent solution and water. The diameter of every particle with soft-magnetic characteristics is blew 0.5 micron. When in use, a few of high-permeability coating materials are sprayed and coated on the surface of products before the products which are not easy for the magnetic separation are abandoned, and then the complete recycle can be realized; and producers can directly spray and coat the coating materials on the products, for example, printing words on the surfaces of plastic films to be recycled, and printing words or figures, such as logo and other forms, on the pop-top cans and beverage plastic bottles. Magnetic particles in the coating materials have soft-magnetic characteristics and high permeability, thus electric magnets or strong magnets with high magnetic energy product are taken as separation tools for separating and recycling the products not easy to separate, which is a key technique changing the present treatment way. After implementing the invention, the magnetic separation way can be used for separating various wastes.

Description

technical field [0001] The invention relates to a magnetic paint beneficial to environmental protection recycling, which belongs to the technical field of environmental protection. Background technique [0002] At present, landfill is the main method of garbage disposal in my country, which is not environmentally friendly and has poor sustainability, causing increasingly serious environmental pollution. There are also many areas that have launched waste incineration power generation projects, which have solved the above-mentioned waste disposal problems to a certain extent, and are more environmentally friendly than landfill methods. However, during the waste incineration process, harmful gases are released, polluting the atmosphere, and after incineration. How to deal with the ashes has become a new environmental problem. [0003] Developed countries have advantages in technology, policy, experience, etc. in the field of garbage classification and recycling, and people can...
