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 dibutyl phenylphosphinate (PPDB) flame retardant composition and an application method thereof. The flame retardant composition is prepared by the steps of compounding one or two of PPDB, 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 PPDB 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 dibutyl 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] With the continuous advancement of science, polymer materials are more and more used in people's production and life, but due to their flammable characteristics, fires occur frequently, which often pose a serious threat to people's lives and property safety, and promote the development of fire protection. The rapid development of fuel industry. With the enhancement of people's awareness of safety and environmental protection and the continuous promulgation of flame retardant regulations, the research on flame retardants with excellent performance is more urgent, especially the new and efficient flame retardant plasticizers are more popular.
