JPS58142949A - Magnetic coating composition - Google Patents

Abstract

PURPOSE:To prepare the titled composition having excellent dispersibility, storage stability and coating characteristics, and giving a dried magnetic layer having excellent magnetic properties, by compounding magnetic powder with a resin binder and a dispersing agent having a specific structure. CONSTITUTION:The objective composition is prepared by compounding (A) 100pts.wt. of magnetic powder having a long axis of 0.8-0.15mu and a short axis of 0.15-0.015mu (e.g. gamma-Fe2O3) with (B) 10-60pts.wt. of a resin binder (e.g. polyurethane) soluble in an organic solvent and (C) 0.5-7.0pts.wt. of an alkenyl or alkylsuccinic acid of romula (R is 4-20C, preferably 6-18C alkenyl or alkyl) or its salt or its acid anhydride, an kneading the mixture in the presence of a proper solvent.

Description

[Detailed description of the invention] In order to take responsibility for the dispersion and give it to nine *ms relatives, I am going to explain it in more detail. In order to avoid the possibility of coating with electrical properties and coatings of 41 mK and drying, the film has excellent nine-way properties.

Regarding china clay with 0-dispersion Ik, various studies have been carried out from one point onwards, and a book has been written on how to improve the dispersibility by adding elevated steel. Therefore, O-@, which uses lecithin as a surfactant, is also a general hook. It is also possible to neutralize the diethylene ester with alkylene ζ and layer it (0).

For epoxy resin, however, from 1k, even if the dispersion in terms of ζζ is limited to π, the magnetic IIO dispersion will necessarily be 1 - 0, but not O.

Nire et al.'s O binder has the ability to adhere to the A board, has excellent physical properties as a tape, and is far superior to just the quality of dispersibility. We don't meet in person.

Thus, regardless of the amount of research on improving the dispersibility of working paints, it is still a must to improve OI.

Because the active steel is molded and dispersed throughout the steel, it has good properties due to the presence of a binder during drilling and because the dispersion is more or less affected by the glue.

If the energy is reduced and the dispersion tube is electrified, because the binder is set, the energy increases again and the dispersion Ilk becomes cloudy, or the energy is low and the particles of the binder are suddenly formed.
