Problems solved by technology

Because chlorinated paraffins are cheap and widely used, but the flame retardancy and plasticizing properties of chlorinated paraffins are not very good, so improving the flame retardancy and plasticizing properties of chlorinated paraffins is a hot topic in the plastic processing industry.
It has been found that the flame retardant plasticizer tricresyl phosphate (TCP) can improve the compatibility and flame retardancy of chlorinated paraffin and materials, but its price is expensive and its application cost is high, so it is limited to a certain extent.

Abstract

The invention relates to a diisopropyl phenylphosphinate (PPDI) flame retardant composition and an application method thereof. The flame retardant composition is prepared by the steps of compounding one or two of PPDI, chlorinated paraffin-52 (short for CP52), tetrachloroethyl silicate (short for STCE), tetradichloropropyl silicate (short for STDE) or tridichloropropyl phenyl silicate (short for STDPE) according to any ratio, and then, uniformly mixing, wherein the weight parts of both PPDI and CP52 are larger than zero. The flame retardant composition provided by the invention has the advantages of synergistic effect among various elements, good compatibility with materials, high flame-retardant efficiency, low cost and the like and can be used as a flame retardant for materials such as polyvinyl chloride, polyurethane, unsaturated resin, epoxy resin and the like so as to have favorable application prospects.

Description

technical field [0001] The invention relates to a flame retardant composition of diisopropyl phenylphosphinate and an application method thereof. The flame retardant composition can be used as a flame retardant for polyvinyl chloride, polyurethane, unsaturated resin, epoxy resin and other materials. Fuel. Background technique [0002] With the rapid development of the polymer material processing industry, there is a great demand for flame retardant plasticizers. Chlorinated paraffins are cheap and widely used, but the flame retardancy and plasticizing properties of chlorinated paraffins are not very good. Therefore, improving the flame retardancy and plasticizing properties of chlorinated paraffins is a hot topic in the plastic processing industry. It has been found that the flame retardant plasticizer tricresyl phosphate (TCP) can improve the compatibility and flame retardancy of chlorinated paraffin and materials, but it is expensive and has high application costs, which ...
