Embodiment 1

[0018] First, the three elements of resin, pigment and additive are stirred and mixed by a mixer, the percentage of resin is 10-85%, the percentage of pigment is 15-90%, and the percentage of additive pump is 0.1-10% ; Then the uniformly mixed material is crushed by a pulverizer; then the pigment is fully dispersed under shear through a two-roller machine, and the two-roller machine mixes and plasticizes the material through two rotating rollers with a certain speed difference. The two rollers rotate in opposite directions so that the material is strongly squeezed and sheared in the gap between the rollers, so as to achieve uniform dispersion and mixing of the pigment.

Embodiment 2

[0020] In embodiment one, add following operation:

[0021] The resin in the step (1) includes cellulose, ammonium polyacid and vinyl acetate resin, and the pigment includes inorganic pigment and organic pigment.

[0022] First, the three elements of resin, pigment and additive are stirred and mixed by a mixer, the percentage of resin is 10-85%, the percentage of pigment is 15-90%, and the percentage of additive pump is 0.1-10% , wherein the resin includes cellulose, ammonium polyacid and vinyl chloride resin, and the pigment includes inorganic pigment and organic pigment; then the uniformly mixed material is crushed by a pulverizer; then the pigment is fully dispersed under shear by a two-roller machine, The two-roll machine mixes and plasticizes the materials through two rotating rollers with a certain speed difference. The two rollers rotate in opposite directions to make the materials be strongly squeezed and sheared in the gap between the rollers, so as to achieve uniform...

Embodiment 3

[0024] In embodiment two, add following operation:

[0025] Auxiliaries in step (1) include drier, toughener, emulsifier, thickener, pigment dispersant, defoamer, leveling agent, anti-skinning agent, matting agent, light stabilizer, antifungal agent and antistatic agents.

[0026] First, the three elements of resin, pigment and additive are stirred and mixed by a mixer, the percentage of resin is 10-85%, the percentage of pigment is 15-90%, and the percentage of additive pump is 0.1-10% , wherein resins include cellulose, polyammonium and vinyl acetate resins, pigments include inorganic pigments and organic pigments, wherein auxiliary agents include driers, tougheners, emulsifiers, thickeners, pigment dispersants, defoamers, Leveling agent, anti-skinning agent, matting agent, light stabilizer, anti-fungal agent and antistatic agent; then the uniformly mixed material is crushed by a pulverizer; then the pigment is fully dispersed under shear by a two-roller machine The two-ro...

Abstract

The invention discloses a production process of pre-dispersed pigment dye color chips. The process comprises the following steps: performing mixing: mixing 10-85% of resin, 15-90% of pigments and 0.1-10% of auxiliary agents through a stirrer under stirring; performing pulverization: pulverizing the uniformly-mixed material by a pulverizer; and performing dispersion: fully dispersing the pigments under cutting through a two-roller machine, mixing the material through two rotating rollers with a certain speed difference of the two-roller machine, performing plasticization, and allowing the two rollers to rotate in opposite directions to strongly press and cut the material between a gap of the rollers, so as to achieve the purpose of uniformly dispersing and mixing the pigments. The pre-dispersed pigment dye color chips provided by the invention have the advantages of good dispersibility, good gloss, high vividness, good transparency, little environmental pollution and good mutual filterproperty; and the process provided by the invention solves the problem that pigment chips produced in the prior art have certain defects in dispersibility, gloss, vividness and transparency.

Description

technical field [0001] The invention relates to the technical field of dye color chips production, in particular to a production process of pre-dispersed pigment dye color chips. Background technique [0002] Pigment color chips, also known as solid color paste, color granules, dry flakes, slices, and pre-dispersed pigments, refer to a solid uniform mixture of pigments and designated carrier resins, that is, high-concentration pigments pre-dispersed in resins. The pigment content in the pre-dispersed pigment chip is relatively high, depending on the system, it can generally be between 50-70%, and the content of the carrier resin is about 30-50%. Some systems such as nitrocellulose (N / C) The pigment chip variety also contains environmentally friendly plasticizers. Pre-dispersed pigment color chips are equivalent to the pigments and resins prepared in proportion to the ink manufacturer. It can be directly loaded into the ink formula, or it can be dispersed into a semi-finishe...
