Abstract

The invention relates to a triazine triphenyl phosphinic acid tert-butyl 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 tert-butyl ester (TTPT) at any proportion, wherein the weight part of the TTPT 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 triazine triphenyl phosphinate tert-butyl flame retardant composition and its application method. 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] With the advancement of science and technology and the wide application of polymer materials, the flame retardant industry has developed rapidly. At the same time, with the continuous improvement of people's living standards, the continuous enhancement of safety awareness, and the continuous introduction of higher requirements for flame retardant regulations, the application of halogen-based flame retardants has been restricted in many aspects, which has great significance for the research and development of halogen-free flame retardants. Strong urgency. Those skilled in the art believe that phosphorus-nitrogen flame retardants are the main fo...
