Problems solved by technology

[0005] This production process has the following disadvantages: 1. The production process adopts the open refining type, which is easy to mix impurities, the product quality is difficult to guarantee, and the dust pollution is serious; 2. The labor intensity is high, the automation and continuous production cannot be realized, and the production efficiency is low. ;3. The discharge from top to bottom between the processes has a lot of leakage, is uneconomical, and the plasticizing effect is poor; 4. The temperature of the material is measured through the fuselage, which has low accuracy and affects product quality.

Abstract

The invention discloses a polypropylene cable protective material and manufacturing technology of submersible pump, which comprises the following parts: 100wt% polypropylene resin, 30-50wt% modifier, 0.2-1wt% lubricant, 0.5-1wt% anti-oxidant and 0.2-0.8wt% copper-proof agent.

Description

technical field [0001] The invention relates to a polypropylene cable sheathing material for a submersible oil pump and a production process thereof. Background technique [0002] In the past, cable sheathing materials for submersible pumps were mostly produced with polyethylene, but because polypropylene has the advantages of high electrical properties, low density, and high mechanical and physical properties, it has gradually replaced polyethylene cable sheathing materials in the mid-1990s. In the early 1990s, China began to develop polypropylene cable sheath materials for submersible pumps. At present, only a few large petrochemical companies can produce them. The production cycle is long, the loss is serious, and the quality is difficult to meet and meet the special needs and use requirements of customers. [0003] At present, the production process of polypropylene cable sheath material for submersible pumps is mainly: [0004] Twin-screw production line process: raw a...
