Plastic with function of seawater corrosion resistance

Abstract

The invention relates to a plastic with a function of seawater corrosion resistance. The formula of the plastic comprises raw materials in parts by weight as follows: 80 parts of HDPE (high-density polyethylene), 11 parts of hydroxyethyl acrylate, 10 parts of vinyl acetate, 15 parts of Ni-Cr alloying powder, 2.5 parts of alginate polysaccharides, 2.5 parts of quaternary ammonium salt of chitosan, 2 parts of isobarbaloin, 3 parts of corilagin and 5 parts of plant fiber. The plastic has the function of seawater corrosion resistance and can be used for a building at the sea.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a seawater corrosion-resistant plastic. Background technique [0002] Seawater has high chloride ion content and high conductivity, so buildings corrode more seriously in seawater. If proper anti-corrosion measures are not taken, the plastics in marine structures will inevitably be severely corroded. Contents of the invention [0003] The object of the present invention is to provide a seawater corrosion-resistant plastic against the deficiencies of the prior art. [0004] The technical scheme adopted in the present invention is as follows: a plastic resistant to seawater corrosion, the formula is composed of the following raw materials in parts by weight: 80 parts of HDPE, 11 parts of hydroxyethyl acrylate, 10 parts of vinyl acetate, 15 parts of Ni-Cr alloy powder, seaweed 2.5 parts of acid polysaccharide, 2.5 parts of polysaccharide quaternary ammonium salt, 2 parts of iso...
