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
The present invention relates to the production technical field of oceanographic engineering material produce raw material, particularly the working method of sea water resistance protection against corrosion PE material.
Background technology
Common PE material has insulation, protection, water proof function at present; But be used for seawater and environment that salt lake saline contacts under; Owing to contain multiple components in seawater and the salt lake moisture content, special soda acid composition can the heavy corrosion oceanographic engineering be used the product appearance, influences ocean operation safety.
Summary of the invention
The object of the invention is to provide a kind of sea water resistance protection against corrosion PE material, can be widely used in all kinds of oceanographic engineering materials that contact with salt lake saline with seawater.
The present invention mainly is made up of linear low density polyethylene resin, high-density polyethylene resin, bisphenol-A epoxy Vinylite, EVA resin, black agglomerate, inhibitor, rheological agent and PE lubricant.
The mass ratio that said linear low density polyethylene resin, high-density polyethylene resin, bisphenol-A epoxy Vinylite, EVA resin, black agglomerate, inhibitor, rheological agent and PE lubricant are formed is 50:12.5～15.0: 12.5～15.0: 13.0～17.0: 4.0～6.0: 2.5～3.0:1.5～2.5:1.5～2.5.
The present invention only need with more than various raw materials mix evenly after, successively through twin screw extrude, tie rod water-cooled, granulation, air-dry, promptly can be made into.Bisphenol-A epoxy Vinylite, EVA (Injecatable EVA Copolymer) resin have erosion resistance (chemical corrosion such as sea water resistance, grease, acid, alkali, antibiotic, nontoxic, tasteless, pollution-free).
Because the present invention utilizes linear resin to improve the weather resistance of product; Being aided with high-molecular weight high-density polyethylene resin enhancing stretching forces the way across and insulating property; Utilize EVA high workability ability; In the extrusion molding production process, with bisphenol-A epoxy Vinylite, EVA resin, be distributed in the material fully and go, the materials used antiseptic property reaches optimal effectiveness.When product is used for the oceanographic engineering material produce and has corrosion proof function, also have excellent results such as weather-proof function and high tensile.Product stability of the present invention is good, the color and luster uniformity.Product has good Corrosion Protection, insulating property and weathering resistance, is mainly used in the particular surroundings that contacts with seawater or salt lake saline.
Oxidation inhibitor according to the invention is made up of antioxidant 1010 and oxidation inhibitor 168, and the mass ratio of antioxidant 1010 and oxidation inhibitor 168 is 1: 1.
