Problems solved by technology

However, since the base resin selected for the halogen-free masterbatch is polyolefin, which has low hardness and small shear during plasticization, it is not easy to disperse the toner, and it is easy to cause the agglomeration of the toner in the masterbatch, which affects the actual use of the masterbatch, and black appears. Points or uneven dispersion, extruded particles, etc.

preparation example Construction

[0041] The present invention also provides a preparation method of a novel halogen-free color masterbatch, comprising the following steps:

[0042] S1. Add each raw material component weighed according to the formula weight into the mixer in turn and stir to obtain a mixture, wherein the working temperature of the mixer is 30°C-75°C, and the working time is 3min-15min.

[0043] S2. Use a twin-screw extruder to extrude and granulate the mixture at a heating temperature of 125°C to 175°C, and dry it for 1.0h to 3.0h at a temperature of 70°C to 85°C to obtain the required halogen-free Masterbatch.

[0044] Specifically, in step S2, the compound will pass through six heating zones in the twin-screw extruder, and the working temperature of each zone is:

[0045] Temperature in the first zone: 125-140°C, preferably 128-132°C;

[0046] Temperature in the second zone: 135-150°C, preferably 138-142°C;

[0047] Temperature in the third zone: 145-160°C, preferably 148-152°C;

[0048]...

Abstract

The invention discloses a novel halogen-free color master batch as well as a preparation method and application thereof. The halogen-free color master batch comprises the following raw material components in parts by weight: 100 parts of polyolefin resin, 3-10 parts of a modifier, 2-5.5 parts of a lubricant, 0.1-0.65 part of an antioxidant and 20-40 parts of organic toner. The polyolefin resin with excellent comprehensive performance is adopted as a base material, the dispersing effect of the toner is remarkably improved by adding the modifier, it is ensured that the surface of the color master batch is smooth and fine in the production process, and the color master batch is uniform in dispersion, bright in color and fine in surface in the halogen-free insulation and sheath production process; and the color stability and reliability of the color cable insulation and sheath are ensured, and the halogen-free insulation and sheath cable can be widely applied to color halogen-free insulation and sheath cables.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a novel halogen-free color masterbatch and its preparation method and application. Background technique [0002] As the pace of urban development in our country continues to accelerate, the demand for cables is also increasing day by day. With the continuous improvement of people's living standards, the demand for cable safety and other aspects is also more urgent. Therefore, as a new type of cable, halogen-free cables, due to its excellent Flame retardant performance, low smoke performance in case of fire, and sufficient escape time can be guaranteed to the greatest extent in case of fire. It has been very well applied in the field of cables, and its demand is very large, and the market is also very wide. Halogen-free cables are mainly colored halogen-free cables and black halogen-free cables. Colored cables are generally produced by adding color masterbatch or toner. Du...
