Embodiment Construction

[0016] The following examples are further explanations and illustrations of the present invention, and do not constitute any limitation to the present invention.

[0017] The ultra-thin flexible magnetic sheet of the present invention is made by mixing synthetic fiber powder, engineering plastic powder or silica gel powder and magnet powder, extruding, injection molding to form a magnetic composite, and then cutting into an ultra-thin flexible magnetic sheet by cutting processes such as laser. The synthetic fiber is polyamide fiber, the engineering plastic is polyphenylene sulfide, and the magnet powder is anisotropic samarium iron nitrogen magnetic powder, anisotropic neodymium iron nitrogen magnetic powder, anisotropic neodymium iron boron magnetic powder, each One or a combination of anisotropic ferrite magnetic powder. The auxiliary agent is a silane coupling agent. In the magnetic composite, the weight percentage of one of the synthetic fiber powder, engineering plastic ...

Abstract

The invention relates to anultrathin flexible magnetic sheet and application. The ultrathin flexible magnetic sheet comprises the following components in percentage by weight: 2-40 parts of synthetic fiber powder, engineering plastic powder or silica gel powder, 59-97 parts of magnet powder and 1-10 parts of assistant. The ultrathin flexible magnetic sheet is prepared by the following steps: uniformly mixing the components in proportion, internally mixing, extruding and chopping the mixture, performing injection molding on the mixture through an injection molding machine to obtain a magnetic complex, carrying out orientationunder the condition of a strong magnetic field while injection molding is carried out, forming an anisotropic magnetic complex, and then cutting the magnetic complex into the ultrathin flexible magnetic sheet with the thickness of 0.02-0.4 mm. The ultrathin flexible magnetic sheet integrates thinness, lightness, flexibility, no leakage of magnetic lines and the like, is particularly suitable for being used as a false eyelash carrier for eye makeup, and is applied as the false eyelash carrier.

Description

【Technical field】 [0001] The invention relates to a magnetic composite body, in particular to an ultra-thin flexible magnetic sheet which integrates ultra-thin, ultra-light, flexible and high magnetic field utilization rate, and is especially suitable for magnetic false eyelashes. 【Background technique】 [0002] At present, magnetic materials have been widely used in various fields such as industry and science and technology. From small magnetic buttons to large magnetic levitation trains, magnetic materials and their applications are inseparable. Most of the magnets used in industrial production are ring or block, which can meet the needs of many applications. But in some special fields, the thinness of magnetism is the first condition. For example, in the field of eye makeup, the traditional false eyelashes for eye makeup are worn by bonding, and its defects are self-evident. For this reason, people try to replace the traditional adhesive eyelashes with magnetic false ey...
