Embodiment 1

[0024] Formulation: LLDPE6201 15%

[0025] Degussa 900L 70%

[0026] PE wax 5%

[0027] EBS 9.4%

[0028] Antioxidant 1076 0.4%

[0029] Coupling agent KH-550 0.2%

[0030] Preparation method: first pre-mix according to the formula ratio, then mix evenly in a high-speed mixer (speed 1500r / min), then add to an internal mixer, banbury at 150°C for 10 minutes, and crush the obtained material with a crushing equipment. Finally, put the pulverized material into a twin-screw extruder to extrude, heat-cut in water, cool, and dry to obtain the required masterbatch.

[0031] The process is: twin-screw first stage temperature 180-200°C, second stage temperature 180-200°C, third stage temperature 180-200°C, fourth stage temperature 180-200°C, fifth stage temperature 170-180°C, sixth stage temperature 170-180°C, The seven-stage temperature is 170-180, the eight-stage temperature is 170-180, and the die head temperature is 190-210.

Abstract

The invention discloses a black master batch and a preparation method thereof. The black master batch comprises the following components in percentage by weight: 5-15% of carrier resin, 70-90% of carbon black, 5-15% of dispersion lubricating agent and 0.6-1% of other auxiliaries. The black master batch prepared by the formula disclosed by the invention has the characteristics of high carbon black concentration, good dyeing effect, good dispersion high blackness brightness and no influence to mechanical properties of products compared with the existing black master batch, thus being widely applied to polyolefine resin and ABS (acrylonitrile butadiene styrene) resin.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-concentration black masterbatch and a preparation method thereof. Background technique [0002] Black masterbatch is mainly used in chemical fiber products (carpets, polyester, non-woven fabrics, etc.), blown film products (packaging bags, cast films, multi-layer composite films, etc.), blown products (medicine and cosmetic containers, paint containers, etc.) , Extruded products (sheets, pipes, cables, wires, etc.), injection products (auto parts, electrical appliances, building materials, daily necessities, toys, sporting goods, etc.). It is easy to use, has no pollution to the molding environment, has uniform and stable coloring, improves the quality of plastic parts, is easy to measure, and can be applied to a molding production system with a high degree of automation. It can integrate coloring, anti-aging agents, and antistatic agents in one place. Made of m...
