Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and relates to a halogen-free flame-retardant vinyl ester resin compound and a preparation method thereof. Background technique [0002] Vinyl ester resin molecules contain vinyl groups at both ends, and the middle skeleton is epoxy resin, which is obtained by the ring-opening esterification reaction of unsaturated organic monocarboxylic acid (usually acrylic acid and methacrylic acid) and epoxy resin. Vinyl ester resin has the advantages of both unsaturated polyester resin and epoxy resin: good molding process, that is, suitable viscosity, room temperature curing and adjustable gel time; good mechanical properties and bonding to fibers It has excellent chemical resistance and is suitable for making various specifications of corrosion-resistant overall FRP products, corrosion-resistant FRP protective layers on the surface of metal structures and concrete structures; various ac...
