Problems solved by technology

The traditional marble-like decorative effects are mostly achieved by extrusion coating, transfer printing, etc., and the materials that are blended and injection-molded by an extruder to imitate marble decorative effects are mostly achieved by adding speckled pigments or adding natural marble particles. Preparation, but its texture is very random, and the consistency of mass production cannot be guaranteed. At the same time, it will cause color migration and discoloration after a period of use, which is not conducive to industrial application

Embodiment 1

[0053] Fully dry 25kg of PC resin (melt flow rate: 10g / 10min) and 25kg of PBT resin (viscosity value: 0.91) in a hot air drying oven at a drying temperature of 110-120°C and a drying time of 2 hours.

[0054] Add 25kg of HIPS resin (melt flow rate: 15g / 10min) to the dried PC resin and PBT resin and mix in a high-speed mixer for 5 minutes at high speed to mix evenly.

[0055] Add 25kg of colorant to the mixed resin, the specific components are: titanium dioxide R103 (Kemon), 24kg; carbon black M717 (Cabot), 0.02kg; brilliant red (IRGAZIN RED) K3840SQ (BASF), 0.05 kg; IRGAZIN YELLOW (IRGAZIN YELLOW) K 2060SQ (BASF), 0.93kg, mix again evenly.

[0056] Then add 3kg grafted POE compatibilizer (trademark is FUSABONDN493, purchased from DuPont), 10kgEVA toughening agent (trademark is EVATANE 28-25, purchased from Exxon Mobil), and 0.3kg antioxidant 1076 (purchased from Taiwan Changchun), mix well again.

[0057] The mixed material is extruded and granulated by a twin-screw extruder t...

Abstract

The invention provides a color master batch, a preparation method of the color master batch and a polymer material. The color master batch is prepared from the following components in percentage by weight: 15 to 45 percent of PC (Polycarbonate) resin, 10 to 30 percent of PBT (Polybutylene Terephthalate) resin, 10 to 30 percent of HIPS (High Impact Polystyrene) resin and 1 to 35 percent of a coloring agent. The polymer material is prepared by carrying out injection molding on 3 to 6 percent of the color master batch and the balance of ABS (Acrylonitrile Butadiene Styrene) or HIPS resin. According to the color master batch provided by the invention, the color master batch can keep a stable natural grain imitating special effect in a long-time injection molding production process; the polymermaterial prepared from the color master batch has bright imitated natural grains; a production technology of a plastic product is the simplest and a complicated surface treatment technology is omitted.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to a color masterbatch, a preparation method thereof and a polymer material. Background technique [0002] The surface treatment of the main parts of the pen in the traditional pen-making industry usually uses methods such as electroplating, spray painting, baking varnish, and electrophoresis, but the wastewater from the electroplating plant will pollute the environment, and the solvents from the electrochemical plant such as spray paint and baking varnish will also pollute the environment. With the advancement of technology, spray-free materials will become more and more popular and valued. [0003] Imitation marble effect decorative materials are widely used in the fields of construction, automobiles, and household appliances. The traditional marble-like decorative effects are mostly achieved by extrusion coating, transfer printing, etc., and the materials that are blended and i...
