一种耐腐蚀环氧树脂复合材料及其制作方法

Corrosion-resistant epoxy resin composite material and preparation method thereof

Abstract

The invention discloses a corrosion-resistant epoxy resin composite material which is characterized by being prepared from the following raw materials in parts by weight: 55-60 parts of epoxy resin, 3-5 parts of dialdehyde starch, 1-2 parts of nano calcium carbonate, 8-10 parts of turpentine, 1.1-2.1 parts of seaweed fiber, 10-13 parts of high-carbon fatty alcohol polyoxyethylene ether, 11-12 parts of octanol, 6-9 parts of polyvinyl butyral, 1-2 parts of a silane coupling agent KH792, 13-16 parts of trifluoroacetic acid ethyl ester, 12-14 parts of isooctyl acetate, 5-8 parts of polyacrylamide and 3-6 parts of an auxiliary agent. A preparation process of the corrosion-resistant epoxy resin composite material disclosed by the invention is simple, and the prepared epoxy resin prepared by adding various additives for modification has the advantages of corrosion resistance, aging resistance, radiation protection, good heat conductivity and the like; and a water-soluble varnish obtained by mixing the epoxy resin with a curing agent has good insulating property, corrosion resistance and rust preventing property and can be used in the fields of insulating oil paints, furniture varnishes, adhesives and the like.
