Embodiment 1

[0014] Carbon black 20%, HDPE 14%, transparent ABS 20%, PE wax 3%, EBS 3%, barium sulfate 40%. The components are added to a low-speed mixer, blended for 10 minutes, and the fully mixed materials are added to the twin-screw extruder to be extruded and granulated to prepare the color masterbatch.

Embodiment 2

[0016] Carbon black 30%, LLDPE20%, LDPE10%, PC20%, EVA wax 6%, SMA3%, magnesium stearate 2%, antioxidant 10106%, antioxidant 1683%. The components are added to a low-speed mixer and blended for 5 minutes. The fully mixed materials are added to a double-rotor continuous mixer for mixing, and then extruded and pelletized by a single-screw extruder to prepare a color masterbatch.

Embodiment 3

[0018] Carbon black 35%, oil-soluble black 5%, LLDPE10%, PMMA10%, SMA2%, ASA28%, ester wax 7%, oxidized PE wax 2%, antioxidant 10101%. Each component is directly put into the internal mixer for banburying for 15 minutes, and then extruded and granulated by the screw extruder to prepare the color masterbatch.

Abstract

The invention discloses a universal high-gloss black masterbatch. The universal high-gloss black masterbatch comprises the following components in percentage by weight: 20-60% of carbon black and / or solvent black, 10-75% of polyethylene, 5-50% of a transparent resin and 4-40% of an additive. The universal high-gloss black masterbatch disclosed by the invention is suitable for most plastics including the polyolefin plastic, the styrene copolymer plastic, the polyester plastic and the polyamide plastic, has good dispersibility and high gloss and can be less affected by the mechanical properties of a colored resin.

Description

Technical field [0001] The invention relates to the field of plastic coloring, in particular to a universal high-gloss black masterbatch. Background technique [0002] Color masterbatch is an aggregate obtained by uniformly loading an ultra-constant amount of pigment or dye in the resin, also known as pigment concentrate. According to the statistics of China Color Masterbatch Committee: In 2011, the national output of color masterbatch exceeded 650,000 tons. Among them, 40% are black masterbatches. Black masterbatch is widely used in agriculture, packaging industry, construction and decoration industry, automobiles, machinery, home appliances, post and telecommunications and other fields. [0003] At present, most black masterbatches are dedicated and color masterbatches with the same or similar resin as the colored resin as the carrier; or general black masterbatches with polyethylene as the carrier. Special black masterbatches such as: Patent CN200610030033.6 discloses black m...
