Abstract

The invention discloses a diamagnetic plastic composite material and a preparation method thereof. The diamagnetic plastic composite material comprises, by weight, 40-76% of plastic, 10-40% of a magnetic material, 10-20% of modified neodymium iron boron, 5-10% of a compatilizer, 0.5-1% of a lubricant and 0.5-1% of an anti-oxidant. Plastic is modified by the magnetic material and the modified neodymium iron boron and then undergoes a concerted reaction with the compatilizer, the lubricant and the anti-oxidant to produce the diamagnetic antistatic plastic composite material. The preparation method has simple processes and a low cost and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a diamagnetic plastic composite material and a preparation method thereof. Background technique [0002] With the rapid development and wide application of computer technology, people can pay without cash when shopping, withdrawing money, borrowing books, and eating, and just take a few ATM magnetic cards. Unfortunately, the following embarrassing situation often occurs: after the user inserts the magnetic card, the terminal device will issue a voice prompt "Hello, your magnetic card is damaged, please pay in cash". This phenomenon is mainly because the magnetism of the magnetic card has been destroyed. [0003] In daily life, plastics are used in all aspects, such as the casing of office equipment, the casing of home appliances, the casing of automobiles, the casing of ATM machines, and so on. If magnetic objects come into contact with these plastic produ...
