Abstract

The invention relates to a POSS-modified flame-retardant, low-smoke and low-toxicity vinyl ester resin composition and a preparation method thereof, and belongs to the technical field of flame retardance. Vinyl ester resin is used as a raw material, one or a combination of any two or three of potassium sulfonate POSS, trapezoidal POSS and phosphorus-containing POSS is used as a flame retardant, methyl ethyl ketone peroxide or the like is used as a curing agent, cobalt isooctanoate or the like is used as an accelerator, and finally the POSS-modified flame-retardant, low-smoke and low-toxicity vinyl ester resin composition is obtained. The vinyl ester resin composition has strong flame retardance, good heat stability and good compatibility of the POSS and the vinyl ester resin, does not contain halogen, can achieve the effects of flame retardance, low toxicity and smoke suppression at the same time, and can be mixed in the molecular level; the preparation method is simple, and is suitable for mass production.

Description

technical field [0001] The invention relates to a POSS modified flame-retardant low-smoke and low-toxicity vinyl ester resin composition and a preparation method thereof, belonging to the technical field of flame retardancy. Background technique [0002] Vinyl ester resin is a product of addition polymerization of epoxy resin and unsaturated monocarboxylic acid containing double bonds. Its technological performance is similar to that of unsaturated polyester resin, and its chemical structure is similar to that of epoxy resin. Therefore, it can be called a combination A new type of resin produced by the advantages of both polyester resin and epoxy resin. As a kind of unsaturated polyester resin, vinyl ester resin has excellent mechanical properties, high temperature resistance, chemical corrosion resistance and fast The advantages of solidification, low viscosity and easy flow have been widely used in FRP corrosion-resistant products and chemical corrosion-resistant projects....
