Embodiment 1

[0018] In this example, 295Kg of tall oleic acid, 100Kg of oleic acid, 440Kg of polyetheramine D400, and 450Kg of wetting agent PPG200 were put into a 200L reactor; the temperature was raised to 120-150°C, and the reaction was kept for 3-5 hours; the temperature was lowered to below 45°C , that is, the finished product of phthalocyanine blue anti-floating dispersant.

Embodiment 2

[0020] In this example, 100Kg of linoleic acid, 220Kg of abietic acid, 85Kg of oleic acid, 150Kg of polyetheramine D230, and 280Kg of ED2000 were put into a 200L reactor; the temperature was raised to 115-145°C, and the reaction was kept for 3-5 hours; the temperature was lowered to 45°C The following is the finished product of phthalocyanine blue anti-floating dispersant

Abstract

The invention relates to a preparation method of a phthalocyanine blue anti-flooding dispersant. The dispersant is prepared from the following substances: a carboxylic acid extracted from natural plants, a polyether modified multifunctional amine and at least one active wetting agent. The method comprises the following steps: putting the substances into a reaction kettle, heating to 100-150 DEG C, and carrying out heat preservation reaction for 3-5 hours to obtain the phthalocyanine blue anti-flooding dispersant. The phthalocyanine blue color paste prepared by using the dispersant has an anti-flooding function. The carboxylic acid extracted from natural plants accounts for 15-45% by weight; the polyether modified multifunctional amine accounts for 30-65% by weight; the active wetting agent accounts for 20-40% by weight. The phthalocyanine blue anti-flooding dispersant prepared by the invention has the advantages of simple technical process, low equipment requirement and high production efficiency; the produced dispersant has a good viscosity reduction effect, has good compatibility when being matched with titanium white inorganic color paste, and has the function of preventing flooding.

Description

technical field [0001] The invention relates to a production method of a phthalocyanine blue anti-floating dispersant, belonging to the technical field of dispersant preparation. Background technique [0002] Phthalocyanine blue pigment has become the preferred pigment for the preparation of blue paste because of its bright color, strong tinting strength, stable chemical properties, and acid and alkali solvent resistance. However, due to the low polarity of the surface of phthalocyanine blue, the particles are not easy to be firmly combined with ordinary dispersants, and there is a certain degree of desorption phenomenon, which leads to the aggregation or precipitation of particles in the dispersion system, and is easy to re-flocculate. The prepared phthalocyanine blue slurry has poor stability. , Poor compatibility with other inorganic pigments and resins, prone to disadvantages such as floating color. [0003] Therefore, it is very necessary to prepare a dispersant that i...
