The publication number is CN102807739A Chinese patent application discloses that aluminum diethylphosphinate (Exolit OP1230) is compounded with MPP for flame retardancy. When the addition amount reaches 30%, it can reach VW-1 level, but it also reduces the mechanical properties. 59%, great loss of performance
The Chinese patent with the authorized announcement number CN101541871B discloses a flame-retardant TPEE. The TPEE hardness is 63D, which is relatively high, and does not reach the higher-grade 0.8mm V0 flame-retardant effect.

Abstract

The invention discloses a halogen-free flame-retardant polyether ester elastomer composition and a preparation method thereof, which is composed of the following components according to weight percentage: polyether ester type TPEE resin 69.4%-81.7%, flame retardant 17.8%- 29.5%, anti-dripping agent 0.2%-0.5%, antioxidant 0.3%-0.6%; wherein, the hardness of the polyether ester type TPEE resin is 28D-45D, and the flame retardant is organic phosphate Burning agent, the composition of the anti-dripping agent is polytetrafluoroethylene. The formulation of the halogen-free flame-retardant polyetherester elastomer composition can effectively meet the halogen-free flame-retardant requirements of low-hardness polyetherester-type TPEE, so that its flame-retardant grade can reach 0.8mm V0, expanding its application field.

Description

technical field [0001] The invention belongs to the field of polymer modified materials, in particular to a halogen-free flame retardant polyetherester elastomer composition and a preparation method thereof. Background technique [0002] Thermoplastic polyester elastomer (TPEE) is a kind of thermoplastic elastomer (TPE), also known as polyester rubber, is a kind of polyester hard segment containing polybutylene terephthalate (PBT) and aliphatic polymer. Linear block copolymer of ester or polyether satin. TPEE has both the elasticity of rubber and the easy processing characteristics of plastic. Its hardness ranges from 25D to 82D, and it has a high degree of design freedom. [0003] The rigidity, polarity and crystallinity of TPEE hard segment make it have outstanding strength and good high temperature resistance, creep resistance, solvent resistance and other excellent characteristics. The elasticity and strength of TPEE are between rubber and plastic. Compared with other ...
