Abstract

The invention relates to a high magnetic conductive additive beneficial for environment protection and recycling and belongs to the technical field of environment protection. The high magnetic conductive additive is added into a plastic product and is a particle with soft magnetic property. The partical size of the particle is in the range of more than or equal to 1mum and less than or equal to 50mum. The magnetic conductivity of the product is over 30,000 Hunters per meter. The high magnetic conductive additive has fine granularity and can be conveniently dispersed and attached into few plastic particles so as to better disperse few plastic particles with magnetic particles into a great amount of plastic particles, or can be directly added into plastic products. The high magnetic conductive additive uses the following products containing a plastic bag, a convenient meal box, a small plastic toy, a pen, a small plastic part, a plastic film and the like. Due to the soft magnetic property and high magnetic conductivity of the high magnetic conductive additive, an electromagnet or a high magnetic energy product strong magnet can be used as a separation tool so as to recover and separate the white pollutants which are originally difficult to be separated. The high magnetic conductive additive is the key technology which changes the existing processing mode.

Description

technical field

[0001] The invention relates to a high magnetic permeability additive and a preparation method, belonging to the technical field of environmental protection. Background technique

[0002] Plastic products are used more and more in daily life, and it is difficult to recycle and degrade, so it is called white pollution. A kind of degradable plastic was invented abroad, which can realize automatic degradation without polluting the environment. However, the application range of this degradable plastic is not wide enough, and it is mainly used in plastic films (agricultural, medical, food packaging), degradable foam nets, plastic bags and disposable fast food boxes. Its production cost is slightly higher than ordinary plastics, and its strength and tension are lower than ordinary plastics, so its promotion has been limited.

[0003] All major cities in China have implemented bagging of household garbage. Landfilling or incineration of bagged garbage for power ge...

Examples

Embodiment Construction

[0020] Below in conjunction with example the present invention is described in further detail. However, the invention is not limited to the examples given.

[0021] The invention is a high magnetic permeability additive beneficial to environmental protection recycling, which is added to plastic products. It is a particle with soft magnetic properties, and the particle size range of the particle is [1 μm, 2 μm]. In this example, the particles with soft magnetic properties are selected from reduced iron particles, the surface of which is coated with an anti-oxidation paint coating, and its magnetic permeability is above 30000 H / m. In addition, ferrite soft magnetic particles can also be used as soft magnetic particles. Since the properties of ferrite materials are relatively stable, there is no need to apply an anti-oxidation layer.
