Abstract
The invention discloses a flame retardant PTT/TPEE composite fiber and a preparation method thereof. The flame retardant PTT/TPEE composite fiber comprises the following components by mass: 60%-85% of PTT, 5%-20% of TPEE, 5%-10% of a flame retardant, 2%-5% of a flame retardant synergist, 2%-5% of a compatilizer, 0.1%-0.5% of an antioxidant, and 0.1%-1% of a lubricant. The flame retardant is one of decabromodiphenyl ethane, melamine polyphosphate, melamine urate, and PSPPP. The flame retardant PTT/TPEE composite fiber provided by the invention has the advantages of good elasticity and toughness, good softness, strong glossiness, good flame retardant and anti-pollution performance, and simple preparation process, and can be used in the indoor fabric or automotive interior decorating fabric field.
Description
Technical field
The present invention relates to technical field of polymer materials, specifically a kind of flame-retarding PTT/TPEE composite fibre and preparation method thereof.
Background technology
Polytrimethylene terephthalate (PTT) is as a kind of new polyester macromolecular material of excellent combination property, be widely used in the fields such as fiber, film, engineering plastics at present, but be used alone PTT and there is the problems such as poor fire, intensity are not high, DIMENSIONAL STABILITY is bad.Polyether ester (TPEE) is polybutylene terephthalate-poly(ethylene oxide)-poly(propylene oxide) thermoplastic elastomer (TPE), it is the block copolymer obtained by copolycondensation by dimethyl terephthalate (DMT), butanediol, polyethylene oxide glycol and/or polypropylene oxide glycol, there is the elasticity of rubber and the intensity of engineering plastics, and will there is better processing characteristics and longer service life compared with rubber, there is the high feature of same intensity compared with engineering material, and pliability and dynamic mechanical better.Therefore, by blended for PTT and the TPEE advantage that better can play both, play complementation, there is good practical value and application prospect.
