Abstract

The invention relates to a phenyl dipropyl phosphinate fire retardant composition and an application method thereof. The fire retardant composition is prepared by compounding and uniformly mixing one or two of PPD (Phenyl Dipropyl Phosphinate), CP52 (Chlorinated Paraffin), STCE (Tetra(chloroethyl) Silicate), STDE (Tetra(dichloropropyl) Silicate) and STDPE (Tri(dichloropropyl) Phenyl Silicate), wherein the weight fraction of PPD and CP52 is both larger than zero. The fire retardant composition disclosed by the invention has the advantages of multi-element synergetic function, good compatibility with the material, high fire retardant efficacy, low cost and the like, can be used as the fire retardant for materials such as polyvinyl chloride, polyurethane, unsaturated polyester resin and epoxy resin, and can achieve a good application prospect.

Description

technical field [0001] The invention relates to a flame retardant composition of dipropyl phenylphosphinate and an application method thereof. The flame retardant composition can be used as a flame retardant for materials such as polyvinyl chloride, polyurethane, unsaturated resin, and epoxy resin. agent. Background technique [0002] At present, there is a large gap between the flame retardant modification rate of plastics in my country and developed countries, and commercially available flame retardants generally have shortcomings such as high price, poor performance, and easy precipitation, so the research on new high-efficiency and excellent performance flame retardants is more urgent . The study found that the organic phosphine flame retardant containing C-P bond in the molecule has a stable molecular structure and high flame retardant performance. It has the advantages of low toxicity, good compatibility with materials, good machinability, and not easy to precipitate. ...
