Abstract

The invention relates to a triazine triphenyl phosphinic acid isopropyl ester flame retardant composition and an application method thereof. The flame retardant composition is prepared by compounding and uniformly mixing any two, three or four of melamine cyanurate (MCA), melamine pyrophosphate (MPP), 9, 10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) and pentaerythritol methyl silicate (PEMS) with triazine triphenyl phosphinic acid isopropyl ester (TTPI) at any proportion, wherein the weight part of the TTPI is greater than zero. The flame retardant composition provided by the invention has the advantages of multielement synergic effect, good flame retardancy, good compatibility with materials, low cost, zero halogen, environmental protection and the like, can be used as a flame retardant for polyester PET, polyester PBT, polyurethane, polypropylene, epoxy resin and other materials, and has excellent application and popularization prospects.

Description

technical field [0001] The invention relates to a flame retardant composition of isopropyl triazine triphenylphosphinate and an application method thereof. The flame retardant composition can be used as polyester PET, polyester PBT, polyurethane, polypropylene, epoxy Flame retardant for materials such as resins. Background technique [0002] Generally, organophosphorus flame retardants are mostly liquid, with small molecular weight, high polarity, poor heat resistance, high volatility, large smoke generation, poor compatibility with materials, small application range, easy migration, low phosphorus content, Disadvantages such as poor flame retardancy. Therefore, there is an urgent need in the market to develop organic phosphine flame retardants with excellent comprehensive properties that can overcome the above-mentioned shortcomings. It is an effective way to improve the flame retardant performance through the synergy of multiple flame retardant elements in the structure ...
