Abstract
Description
technical field
[0001] The invention belongs to the field of pigments, and relates to a pigment dispersion and a preparation method thereof, in particular to a sunfast brilliant red BBC dispersion and a preparation method thereof. Background technique
[0002] When manufacturing water-based inks, it is very important to choose the right pigment. Most manufacturers will provide several pigments with different properties, so that pigments can be selected for special systems. Hue is the primary consideration in pigment selection, followed by gloss, chemical resistance, ease of dispersibility and compatibility with other components. The dispersion and stabilization of pigments play an important role in the final performance and storage stability of coatings. Due to the variety of pigment and resin systems, choosing the right dispersion process is a complex task. The impact of traditional dispersion processes in Shinjuku can be attributed to three variables: pigments, dispersan...
Examples
Embodiment 1
[0019] (1) Take 25 parts of sunfast bright red BBC, 5 parts of gum arabic, 7 parts of carboxymethyl cellulose, 4 parts of hydroxyethyl cellulose, 4 parts of carrageenan, and 130 parts of water respectively by weight, and mix the above-mentioned various ingredients Put it into the stirred tank, mechanically stir, the stirring speed is 300rpm, and the stirring time is 20min;
[0020] (2) Take again by weight 8 parts of short-oil water-based alkyd resin, 3 parts of methyl etherified amino resin, 7 parts of β-glucan, 5 parts of polyethylene glycol 400, and 3 parts of MOA-3 emulsifier, Stir the above ingredients again, the stirring speed is 300rpm, and the stirring time is 10min;
[0021] (3) The dispersion stirred in the step (2) is then sheared with a shearing machine, the shearing speed is 6000r / min, and the shearing time is 35min. After shearing, it is sealed and stored, and it is a Brilliant Red BBC dispersion.
Embodiment 2
[0023] (1) Take 10 parts of sunfast bright red BBC, 9 parts of gum arabic, 3 parts of carboxymethyl cellulose, 2 parts of hydroxyethyl cellulose, 6 parts of carrageenan, and 110 parts of water respectively by weight, and mix the above-mentioned various ingredients Put it into the stirred tank, mechanically stir, the stirring speed is 100rpm, and the stirring time is 50min;
[0024] (2) Take 4 parts of short-oil water-based alkyd resin, 9 parts of methyl etherified amino resin, 3 parts of β-glucan, 10 parts of polyethylene glycol 400, and 5 parts of MOA-3 emulsifier by weight, Stir the above ingredients again, the stirring speed is 100rpm, and the stirring time is 30min;
[0025] (3) The dispersion stirred in the step (2) is then sheared with a shearing machine, the shearing speed is 4000r / min, and the shearing time is 15min. After shearing, it is sealed and stored, and it is a Brilliant Red BBC dispersion.
Embodiment 3
