Problems solved by technology

[0004] Chlorinated polyethylene (referred to as CPE) is a polymer material obtained from high-density polyethylene through chlorination substitution reaction. It can be blended with PVC resin to improve the low temperature resistance of the product. However, when the blending temperature with PVC is high It is easy to agglomerate, it is not easy to cut the material, the PVC is not mixed well when the temperature is low, and the production process is unstable

Embodiment Construction

[0013] A kind of chlorinated polyethylene and resin blend processing method is characterized in that: comprises the following steps:

[0014] (1) Stir the resin, dioctyl phthalate, calcium-zinc composite stabilizer, calcium carbonate, and toner in the mixer according to the normal production process;

[0015] (2) When stirring to 80°C, turn to low-speed stirring, quickly add chlorinated polyethylene, stir for 10 seconds, and put it into the internal mixer;

[0016] (3) When the internal mixer reaches 130°C, the material is discharged, and the two-stage machine is used for production.

Abstract

A chlorinated polyethylene and resin blending process method includes steps: (1) well stirring resin, dioctyl phthalate, a calcium-zinc composite stabilizer, calcium carbonate and color powder in a stirring machine according to a normal production process; (2) when stirring to 80 DEG C, starting low-speed stirring, quickly adding chlorinated polyethylene, stirring for 10s, and adding into an internal mixer; (3) when the temperature of the internal mixer reaches 130 DEG C, discharging, and adopting a two-stage machine for production. The chlorinated polyethylene and resin blending process method has advantages that power materials are guaranteed against agglomeration, and uniformity in mixing of the power materials, stability of a production process and improvement of product quality are realized.

Description

[0001] Technical field: [0002] The invention relates to the field of wire and cable materials, in particular to a processing method for blending chlorinated polyethylene and resin. [0003] Background technique: [0004] Chlorinated polyethylene (referred to as CPE) is a polymer material obtained from high-density polyethylene through chlorination substitution reaction. It can be blended with PVC resin to improve the low temperature resistance of the product. However, when the blending temperature with PVC is high It is easy to agglomerate, it is not easy to cut the material, and the PVC is not mixed well when the temperature is low, and the production process is unstable. [0005] Invention content: [0006] The purpose of the present invention is to provide a new processing method for blending chlorinated polyethylene and resin, which can ensure that the powder is not agglomerated, the powder is mixed evenly, the production process is stable, and the product quality is wel...
