Problems solved by technology

[0002] With the rapid development of social economy, wires and cables have been widely used in all walks of life. However, in the production process of existing cable materials, the matrix material has poor fluidity, uneven mixing between materials, and color mixing. Insufficient, and the interaction between the matrix and the additive, the stability is poor, yellowing is easy to occur, and the defective rate is high; in addition, after mixing, the matrix material has poor adhesion and is not easy to knead; moreover, the existing cable materials Although a certain amount of lubricant is added, the appearance of the product is still rough, uneven and dull when extruded

Embodiment 1

[0027] A polyvinyl chloride color masterbatch suitable for high-speed production of automotive wires and cables and a preparation method thereof, the active ingredient is composed of the following raw materials in weight fractions, each part is calculated as 1 kg, and the following steps are adopted:

[0028] (1) premixing: respectively take by weighing 3 kilograms of calcium-zinc stabilizers and 45 kilograms of polyvinyl chloride in the polyvinyl chloride color masterbatch suitable for high-speed production of automobile wire and cable, and premix them with a low-speed mixer to obtain premixed materials for subsequent use; Wherein, the screw speed during stirring is 550 R / min, the temperature is 20° C., and the stirring time is 13 minutes. This step can make the added material more divergent and evenly mixed with the base material, avoiding poor plasticization and graininess on the surface of the product.

[0029] (2) Mix the premixed material obtained in the above steps and ...

Abstract

The invention relates to polyvinyl chloride color masterbatch suitable for high-speed production of automobile wires and cables and a preparation method of the polyvinyl chloride color masterbatch. The active components of the polyvinyl chloride color masterbatch consist of the following raw materials in parts by weight: 45-55 parts of polyvinyl chloride, 5-12 parts of titanium dioxide, 4-8 partsof a brightening agent, 3-6 parts of a calcium zinc stabilizer, 1-3 parts of oxidized polyethlene wax, 1-3 parts of a surface treating agent, 1-3 parts of zinc stearate, 1-3 parts of a coupling agentand 25-35 parts of pigment. The polyvinyl chloride and the oxidized polyethlene wax are pre-stirred, so that substrate materials are stable and uniform when being mixed, the polymerizing degree is higher, when the temperature of masterbatch substrates is lower than that of squeezed materials, diverging and coloring of masterbatch are facilitated, the fusion degree of the masterbatch substrate materials and the squeezed materials is increased, and high-speed squeezing is facilitated; and through measures of added materials and a production technology, the masterbatch materials are more suitablefor high-speed squeezing of automobile wires and cables, the production efficiency is greatly improved, and unnecessary losses caused by color problems are reduced.
