Problems solved by technology

The high-branch epoxy vinyl ester resin composition can effectively and greatly improve the toughness and elongation of epoxy vinyl ester resin, and the appearance of the resin is uniform without delamination. The performance is not good, it is easy to be corroded by seawater in the marine environment, resulting in serious performance degradation and greatly shortened service life

Abstract

The invention provides a seawater resistant vinyl ester composite material. The seawater resistant vinyl ester composite material comprises, by weight, 40-50 parts of epoxy vinyl ester resin, 0.4-1.8 parts of a curing agent, 0.6-2 parts of an accelerant, 2-4 parts of organic rectorite, 12-18 parts of nanometer kaolin, 1-4 parts of a release agent, 10-15 parts of styrene and 5-8 parts of chemigum. The seawater resistant vinyl ester composite material is good in seawater resistance, can effectively lower the adverse effect of seawater corrosion and is long in service life.

Description

Technical field: [0001] The invention relates to a composite material, in particular to a seawater-resistant vinyl ester composite material and a preparation method thereof. Background technique: [0002] Epoxy vinyl ester resin (EVER) is a resin obtained by ring-opening addition reaction of epoxy resin and methacrylic acid or acrylic acid. It has excellent mechanical properties and corrosion resistance of epoxy resin. , and unsaturated polyester resin has good process performance, and the composite materials made of it as matrix resin are widely used in electrical insulation, automotive components, sporting goods and land and sea transportation. Seawater is the most abundant and highly corrosive electrolyte solution in nature, containing 3.2%-3.75% NaCl and other salts, dissolved oxygen and carbon dioxide and other gases, and a large number of marine organisms. The complex marine environment has caused damage to the seawater. The corrosion of composite materials will affec...
