Embodiment 1

[0140] Preparation of Pigment Preparation XP303-C (Pigment Concentration = 85%)

[0141] 6800 g of Pigment Red 254 pigment (available as SR2P from Cinic company) was mixed with 1,200 g of dispersant Disperplast 1018 (supplied by BYK company) and ground.

[0142] The dry grinding unit is a discontinuous unit equipped with 4 rotors.

[0143] Process parameters: 1 minute at a peripheral speed of 6 m / s, 14 minutes at a peripheral speed of 15 m / s and then 6 minutes at a peripheral speed of 25 m / s; the temperature reaches 72°C.

[0144] The pigment preparations thus obtained correspond to microgranules.

[0145] The particle size values ​​of the pigment additives in the pigment preparation are as follows (analyzed in butyl acetate dispersion with the aid of a laser Beckman Coulter particle size analyzer):

[0146] D10 = 0.571 μm

[0147] D50=0.790μm

[0148] D90=1.034μm

[0149] The particle size of the microparticles: in the range of 80-350 μm.

Embodiment 2

[0151] Preparation of Pigment Preparation XP901 (Pigment Concentration = 80%)

[0152] 6400 g of carbon black pigment PBL-7 (Carbon Black Special Black 100 from the company Orion) were mixed with 1600 g of dispersant Disperplast 1018 (by BYK.) and ground by means of a discontinuous dry mill equipped with 4 rotors. Process parameters: 1 minute at a peripheral speed of 6 m / s, 14 minutes at a peripheral speed of 15 m / s and then 6 minutes at a peripheral speed of 25 m / s; the temperature reaches 132°C. The composition obtained is in the form of dust-free granules.

[0153] D50 of the pigment additive in the pigment preparation (measured as in Example 1) = 1.5 μm

[0154] The particle size of the microparticles: 80-350 μm

Embodiment 3

[0156] Preparation of Pigment Preparation XP307C (Pigment Concentration = 90%)

[0157] 5400 g of Pigment Red 101 pigment (Bayferrox 130M from Lanxess) and 600 g of dispersant Disperplast 1018 (by BYK) were mixed and ground by means of a discontinuous dry mill equipped with 4 rotors.

[0158] Process parameters: 1 minute at a peripheral speed of 6 m / s, 14 minutes at a peripheral speed of 25 m / s. The temperature reaches 50°C.

[0159] The composition obtained has the form of a free-flowing powder.

[0160] D50 of the pigment additive in the pigment preparation (measured as in Example 1) = 1.2 μm

[0161] The particle size of the powder is <50μm

Abstract

The invention concerns a pigmentary preparation having universality of use in tinting plastics.

Description

technical field [0001] The present invention relates to pigment preparations (preparations for pigments) intended for the reinforcement and coloration of plastic materials (preparations for pigments), comprising pigments, and / or other additives and / or their use as dye concentrates or filler. Background technique [0002] In order to obtain objects and finished products made of plastic or rubber, it is generally necessary to introduce polymers in the base stock, ie some substance suitable to give them the properties desired in the final product. These substances may be: substances that impart color (hue) to the material, such as pigments or dyes; or substances that impart functionality to the finished product (for example, improved resistance to fire and / or light); or even, Substances that improve the mechanical and / or thermal properties of the final article (finished product). Usually, additives (often defined as process additives) are also used in order to protect said po...
