Abstract

A seawater corrosion resistant PE (polyethylene) material relates to the technical field of production of raw materials of ocean engineering materials, and is mainly made of linear low-density polyethylene resin, high-density polyethylene resin, bisphenol A epoxy vinyl ester resin, EVA (ethylene-vinyl acetate) copolymer, black master batches, antioxidant, rheological agent and PE lubricant. The seawater corrosion resistant PE material is high in stability and uniform in color, has excellent corrosion resistance, insulating property and weather fastness, and is mainly used for special environments contacting with seawater or water in salt lakes.

Description

technical field [0001] The invention relates to the technical field of producing raw materials for marine engineering materials, in particular to a production method of seawater-resistant and anti-corrosion PE materials. Background technique [0002] At present, ordinary PE materials have the functions of insulation, protection, and water isolation, but they are used in environments that are in contact with seawater and salt lake water. Since seawater and salt lake water contain various components, especially acid and alkali components will seriously corrode marine engineering products. appearance, affecting the safety of marine operations. Contents of the invention [0003] The purpose of the present invention is to provide a seawater-resistant and anti-corrosion PE material that can be widely used in various marine engineering materials in contact with seawater and salt lake water. [0004] The invention is mainly composed of linear low-density polyethylene resin, high-...
