Embodiment Construction

[0010] A kind of preparation method of the environment-friendly iron oxide black that is used for toy paint, comprises the following steps:

[0011] (1) Bentonite was calcined at 700°C for 5 hours, taken out and cooled, and added tricresyl phosphate equivalent to 2% of its weight, 2% monoethanolamine, stirred at 1700 rpm for 40 minutes, dried and ground into nano-powder , to obtain the modified nano-bentonite for subsequent use;

[0012] (2) Get 203 6 parts of octyl phenolic resins (kg), 18 parts of ethyl acetate, stir 5 minutes at 30 ℃, mix, then add iron oxide black, stir 20 minutes, finally add 5 parts of modified nano-bentonite 1. 0.3 parts of sodium petroleum sulfonate, 0.4 parts of dimethyl carbonate, heated in a water bath to 55°C, and then kept warm for 6 minutes, taken out, sheared at 2000rpm at high speed for 15 minutes, taken out, dried, and obtained.

[0013] The iron oxide black product performance analysis data that present embodiment produces is as followi...

Abstract

The invention discloses a method for preparing environment-friendly black iron oxide for toy paint. The method comprises the following steps: (1) calcining bentonite for 5-6 hours at 700-800 DEG C, taking out and cooling down, then adding tricresyl phosphate 1-2% the weight of the bentonite and monoethanolamine 1-2% the weight of the bentonite, stirring for 30-40 minutes, then stoving and grinding into nanopowder so as to obtain modified nanometer bentonite for later use; (2) weighing 4-6 parts of octyl group phenolic resin 203 and 15-20 parts of ethyl acetate, stirring for 3-5 minutes at 20-30 DEG C so as to mix uniformly, then adding black iron oxide, stirring for 10-20 minutes, finally, adding 3-5 parts of modified nanometer bentonite, 0.1-0.3 part of petroleum sodium sulfonate, and 0.2-0.4 part of dimethyl carbonate, heating up to 45-55 DEG C in water bath, then performing heat preservation for 5-7 minutes, taking out, shearing for 10-15 minutes at high speed of 2000-2400 rpm (revolutions per minute), taking out, and stoving so as to obtain the black iron oxide.

Description

technical field [0001] The invention relates to the field of iron oxide black, in particular to a preparation method of environment-friendly iron oxide black used for toy paints. Background technique [0002] Ferric oxide, chemical formula Fe 3 o 4 . Also known as iron oxide black, magnet, magnet, it is a black crystal with magnetic properties, so it is also called magnetic iron oxide. Iron oxide black is widely used, but its performance indicators are limited, and there is an urgent need to customize special varieties in all directions. Contents of the invention [0003] The object of the present invention is to provide a kind of preparation method of the environment-friendly iron oxide black that is used for toy paint. [0004] The above purpose is achieved through the following schemes: [0005] A kind of preparation method of the environment-friendly iron oxide black that is used for toy paint, it is characterized in that: comprise the following steps: [0006] (...
