Abstract
The invention discloses an environmental protection flame resistant PTT/TPEE composite material and a preparation method therefor. The environmental protection flame resistant PTT/TPEE composite material comprises the following ingredients, by weight, 60%-85% of PTT, 5%-20% of TPEE, 5%-10% of halogen free fire retardants, 2%-4% of compatilizers, 0.5%-2% of aging resistant agents, 0.1%-0.5% of anti-oxidants, 0.1%-1% of lubricants and 0.1%-1% of pigments. The halogen free fire retardants are a mixture of phosphorus-based flame retardant polysulfonyldiphenylene phenyl phosphonate and silicon-based flame retardant polydimethylsiloxane with a weight ratio of 3:1. The beneficial effects are that the PTT/TPEE composite material has excellent flame resistance, the limit oxygen index is more than 35%, the composite material is advantaged by halogen-free, low-smoke and environmental protection, and meets the UL94V-0 level flame retardation level requirement, the processability is good, the chemical resistance is high, the anti-aging service life is long, and the composite material is suitable for textile fabric or engineering plastics fields.
Description
Technical field
The present invention relates to technical field of polymer materials, specifically a kind of environmental protection flame retardant PTT/TPEE matrix material and preparation method thereof.
Background technology
Poly(Trimethylene 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 the problems such as PTT exists that flame retardant resistance is bad, ageing resistance is strong, dimensional stability is not high.Polyether ester (TPEE) is polybutylene terephthalate-polyethylene oxide-poly(propylene oxide) thermoplastic elastomer, it is the segmented copolymer obtained by copolycondensation by dimethyl terephthalate (DMT), butyleneglycol, polyethylene oxide glycol and/or polypropylene oxide glycol, there is the elasticity of rubber and the intensity of engineering plastics, and with rubber phase than having better processing characteristics and longer work-ing life, there is the high feature of same intensity compared with engineering material, and snappiness and dynamic properties better.Therefore, by blended for PTT and the TPEE advantage that better can play both, play complementary action, there is good practical value and application prospect.
