A polyolefine particle with electromagnetic shielding function for plastics is prepared from polyolefine plastics (60-84 wt.%), high-B tourmalinite ore powder (5-15), inorganic filler (5-10), disperser (0.5-1) and aluminium powder (5-15). Said tourmalinite ore powder is the silicate containing B, Al, Si, Mg, Mn, Zn and Ti. The resultant plastics has high effect to shield electromagnetic wave.
Description
technical field [0001] The invention relates to a plastic master batch, in particular to a polyolefin plastic master batch with electromagnetic shielding function. Background technique [0002] At present, some equipment or products with electromagnetic waves are encountered in industrial production or daily life, and some existing packaging materials do not have the function of electromagnetic shielding, especially some products such as magnetic cards will damage and fail the magnetic cards when they encounter electromagnetic waves. Contents of the invention [0003] The purpose of the present invention is to solve the problem that some equipment or products with electromagnetic waves will be encountered in industrial production or daily life in the prior art, but some existing packaging materials do not have the function of electromagnetic shielding, especially when some products such as magnetic cards encounter The problem that the magnetic card will be damaged and inva...
