Problems solved by technology

At the same time, these products also have shortcomings, such as high cost, and the magnetic material used in the product is iron oxide powder of 1-3 microns. Due to the large particle size of the functional powder material, the developing effect is poor and the developing stripes are not good. uniform

example 1

[0019] According to the experimental process of the patent publication number CN1741207, the nanometer iron ferric oxide powder with an average grain size of about 20nm was prepared. Take 10g of the prepared nanometer ferric oxide magnetic powder, add 50mL of absolute ethanol, ultrasonically disperse for 2min, add 10mL of silane coupling agent KH570, fully stirred, placed in a ball mill tank, milled by a planetary ball mill for 5 hours, the solution was separated by a magnet and centrifuged, washed 3 times with absolute ethanol, heated to 80°C and dried to obtain modified magnetic powder body. Add 1 g of the prepared modified magnetic powder into 100 mL of HFE-7100, then add 1 g of titanium dioxide, place it in a ball mill jar, and mill it for 5 hours in a planetary mill to prepare a nano-magnetic developer for use. Take a magnetic card and place it in a horizontal plane, dropper or spray nano-magnetic developer on the magnetic strip of the magnetic card, let it dry naturally ...

example 2

[0021] According to the experimental process of the patent publication No. CN1741207, the nanometer ferric oxide powder with an average grain size of about 20nm was prepared. Take 10g of the prepared nanometer ferric oxide magnetic powder, add it to 100mL distilled water, add 1g of titanium dioxide, Ultrasonic dispersion for 3 minutes, adding 0.55 g of sodium dodecylbenzene sulfonate and stirring thoroughly, ultrasonic dispersion for 5 minutes, placed in a ball mill jar, and milled by a planetary mill for 3 hours to prepare a nano-magnetic developer. The magnetic imaging test was as in Example 1.

example 3

[0023] According to the experimental process of the patent publication number CN1741207, the nano-ferric oxide powder with an average grain size of about 20nm was prepared. Take 0.1g of the prepared nano-ferric oxide magnetic powder, add 100mL of absolute ethanol, and ultrasonically disperse for 1min. Add 0.1mL titanate coupling agent NXT-201, stir well, add 0.1g iron oxide red, 0.2g sunfast scarlet, put in a ball mill jar, and mill for 6 hours in a planetary ball mill to prepare a nano-magnetic developer. The magnetic imaging test was as in Example 1.

Abstract

The invention relates to a nano developer and a preparation method thereof. The preparation of the nano developer includes the steps as follows: the raw materials of magnetic nano materials, a surface dispersing finishing agent, tinting colors and medium solutions are arranged inside a container with a certain proportion; and then the nano developer is obtained by mixing and dispersing the mixture evenly. The nano developer prepared with the invention has the advantages of moving directionally in the effect of the magnetic filed, developing the magnetic recoding materials such as tap and magnetic strip, simple preparation and easy use.

Description

technical field [0001] The invention relates to a magnetic developer and a preparation method thereof, in particular to a nano-magnetic developer and a preparation method thereof, which is a type of application research of nano-magnetic materials in the field of magnetic recording. Background technique [0002] At present, in the domestic products, the corresponding magnetic developer has not been reported, and foreign products have been sold in the market, such as Q-view Magnetic Developer and Sprague-Mag SM-1, etc. These products mainly disperse magnetic materials in highly volatile In the permanent HFE-7100 or FCFC-141b, the magnetic recording data can be displayed on the magnetic medium by spraying or dripping. These products have great advantages in use. The dispersion medium used not only has high volatility, but also has the characteristics of being non-flammable and not destroying the ozone layer of the atmosphere, and has little environmental pollution. At the same...
