Embodiment 1

[0044] 1. Add 60 parts of polypropylene resin, 40 parts of titanium dioxide, 17 parts of dispersant, 18 parts of polylactic acid, 24 parts of flame retardant and 8 parts of coupling agent into the low-speed mixer in sequence, and mix at 100 rpm at room temperature for 2 ~5 minutes. Add 3 parts of additives and 4 parts of high-temperature stabilizer to the mixture, and then use a high-speed mixer to mix at a high speed of 2000 rpm for 8-10 minutes.

[0045] 2. Use the screw extruder to plasticize and extrude the mixture obtained in step 1. The temperature settings of the five temperature zones in the extruder are 170°C, 180°C, 190°C, 180°C, and 190°C, and the speed of the main engine is 500 ~800 rpm, the extrudate is cooled at 10-20°C.

[0046] 3. After hardening, use a granulator to granulate the resulting product, pass through a vibrating sieve, remove irregular products, and ventilate. After the masterbatch is completely cooled and dried, the finished product can be obtaine...

Abstract

The invention discloses an environment-friendly, halogen-free and flame resistant polypropylene color master batch. The environment-friendly, halogen-free and flame resistant polypropylene color master batch is prepared from the following raw materials: a polypropylene resin, titanium dioxide, a dispersant, a polylactic acid, a flame retardant, a coupling agent, an auxiliary agent and a high-temperature stabilizer. The invention also discloses a preparation method of the environment-friendly, halogen-free and flame resistant polypropylene color master batch.

Description

technical field [0001] The invention belongs to the field of color masterbatch manufacturing, and more specifically, the invention relates to an environment-friendly halogen-free flame-retardant polypropylene color masterbatch and a preparation method thereof. Background technique [0002] With the advancement of science and technology and the improvement of living standards, polymer materials such as plastics and rubber, especially synthetic polymers, are becoming more and more important in people's lives, and their applications are showing a trend of expanding year by year. However, most organic polymer materials have different degrees of flammability in the air. In order to realize their applications in many industries such as military, aerospace, transportation, electric power and civil use, their flame-retardant modification has become a new topic. At present, the ideal method of flame retardant modification of plastics is generally to improve the fire resistance of pla...
