Abstract

The invention discloses a pigment fast brilliant red BBC dispersion and a preparation method therefor. The pigment fast brilliant red BBC dispersion comprises the following components in parts by weight: 10-25 parts of pigment fast brilliant red BBC, 5-9 parts of Arabic gum, 3-7 parts of carboxymethyl cellulose, 2-4 parts of hydroxyethyl cellulose, 4-6 parts of carrageenan, 4-8 parts of short-oil water-based alkyd resin, 3-9 parts of methylated amino resin, 3-7 parts of beta-glucan, 5-10 parts of polyethylene glycol 400, 3-5 parts of a MOA-3 emulsifier and 110-130 parts of water. The preparation method for the pigment fast brilliant red BBC dispersion comprises the following steps of: (1) putting the components in parts by weight into a stirring kettle, and mechanically stirring the components; and (2) shearing the dispersion which is stirred in the step (1) for 15-35 minutes by use of a shearing machine at shearing rotation speed of 4000r / min-6000r / min, and sealing up the dispersion for safekeeping after shearing, thereby obtaining the pigment fast brilliant red BBC dispersion.

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...
