Abstract

The invention discloses a synthesis method of improved efficient flame-retardant epoxy ethyl ester resin. Disphenol A epoxy resin is used as a synthesis material, and other synthesis materials includechain extender binary acid containing halogen element, unsaturated monoacid, flame-retardant aid, catalyst, polymerization inhibitor, antioxidant and crosslinking agent. By introducing the reactive chain extender containing flame-retardant element and adding the solvent-type organic phosphate flame-retardant aid for compounding, flame-retardant synergism between the chain extender and the flame-retardant aid is brought into full play to prepare the efficient flame-retardant epoxy ethyl ester resin.

Description

technical field [0001] The invention belongs to the field of synthesis of organic polymer compounds, in particular to a synthesis method of an improved high-efficiency flame-retardant epoxy vinyl ester resin. Background technique [0002] Vinyl ester resin is prepared by chemical reaction of epoxy resin and unsaturated monobasic acid through ring-opening addition. It retains the basic chain segment of epoxy resin, and has the good process performance of unsaturated polyester resin. It inherits the excellent characteristics of epoxy resin, and has better curability and formability. It can be dissolved in styrene and acrylic acid. System monomer. Due to the advantages of both epoxy and unsaturated, its application field is constantly expanding, mainly used in the chemical industry with strict requirements such as chemical corrosion resistance, acid and alkali resistance, such as in the manufacture of desulfurization and denitrification equipment in new energy wind power and e...
