Embodiment 1

[0018] Under normal temperature and pressure, the following components and percentages by weight: ABS 40%, titanium dioxide 40%, polyethylene wax 8%, MBS 9%, phenolic antioxidant 1076 1%, stearic acid 1%, calcium carbonate 1% %, after grinding into powder, carry out high-speed mixing in a high-speed mixer for 10 minutes, and use a twin-screw extruder to carry out melt blending, the temperature is controlled at 190 ° C, and the screw speed is 200r / min. Refining to disperse the pigment uniformly in the carrier resin, and then carry out granulation, drying, packaging and other processes to obtain the color masterbatch of the present invention.

Embodiment 2

[0020] Under normal temperature and pressure, the following components and weight percentages: AS 25%, SEBS 20%, titanium dioxide 30%, EBS 10%, phosphite 1681%, polysilicone 2%, wollastonite 12%, After being ground into powder, mix at a high speed for 15 minutes in a high-speed mixer, and use a twin-screw extruder for melt blending. The temperature is controlled at 200°C, and the screw speed is 100r / min. The pigment is uniformly dispersed in the carrier resin, and then granulation, drying, packaging and other processes are carried out to obtain the color masterbatch of the present invention.

Embodiment 3

[0022] Under normal temperature and pressure, the following components and weight percentages: PS 5%, K glue 10%, SBS 6%, SEBS 15%, SIS 5%, titanium dioxide 13%, lithopone 5%, azo pigment 0.5% %, oxidized polyethylene wax 5%, paraffin wax 1.5%, monoglyceride 5%, ACR4013%, stearic acid 1%, lanthanum stearate 2%, phenolic antioxidant 1010 1%, phosphite 6263%, DOP 4%, acetyl tributyl citrate 4%, talc powder 5%, barium sulfate 6%, after grinding into powder, mix in a high-speed mixer, first use a banbury mixer to banbury, and then use a screw extruder to make The color masterbatch of the present invention is obtained by granulating.

Abstract

The invention discloses a color master batch for hard PVC and a preparation method thereof. The color master batch for the hard PVC consists of the following components in percentage by weight: 20 to 70 percent of carrier, 0.01 to 70 percent of toner, 0 to 40 percent of dispersant, 0.1 to 2 percent of antioxidant, 0 to 10 percent of processing aid and 0 to 40 percent of filler. The invention provides the color master batch for the hard PVC with environmental protection, no pollution, high dispersion and good thermal stabilizing effect; and when the color master batch is applied to coloration of a hard PVC product, the color master batch can solve the pollution problem of toner coloration and solve the problem of color change of the common PVC color master batch. The color master batch of the invention can reduce the problems of product flow line, non-uniform color, great color difference and the like, and can improve the impact resistance of the hard PVC product. The preparation method for the color master batch for the hard PVC is simple and practical, and has broad application prospect.

Description

technical field [0001] The invention relates to the field of plastic coloring, in particular to a color masterbatch used for extrusion of rigid PVC and coloring of injection molded parts. Background technique [0002] Polyvinyl Chloride (hereinafter referred to as PVC) is a non-toxic, odorless white powder. In China, the production and consumption of PVC rank first among the five general-purpose resins. According to statistics, the total output value of PVC in China in 2008 was close to 67 billion yuan. The market for PVC downstream products is even wider. In 2008, the output value of downstream products using PVC as raw material exceeded 100 billion yuan. In the field of rigid PVC, profiles and profiled materials are the largest consumption areas of PVC in my country, accounting for about 25% of the total consumption of PVC. They are mainly used to make doors and windows and energy-saving materials, and PVC pipes are the second largest consumption area. , accounting for a...
