Abstract

The invention discloses a flame retardation enhanced PTT/TPEE composite material and a preparation method therefor. The flame retardation enhanced PTT/TPEE composite material comprises the following ingredients, by weight, 45%-85% of PTT, 5%-25% of TPEE, 5%-15% of reinforcing agents, 4%-10% of halogen-free flame retardants, 2%-4% of compatilizers, 0.5%-2% of aging resistant agents, 0.1%-0.5% of anti-oxidants and 0.1%-1% of lubricants. The reinforcing agent is one of organo montmorillonite, nano calcium carbonate, gas phase nanosilicon dioxide and glass fibers with surfaces processed through activity processing of coupling agents. The halogen-free fire retardants are a mixture composed of of polysulfonyldiphenylene phenyl phosphonate, polydimethylsiloxane and polytetrafluoroethylene with a weight ratio of 5:4:1. The beneficial effects are that the composite material has advantages of high intensity, good flame retardation, high chemical resistance, high heat resistance and the like, the processability is good and the ageing resistance is high.

Description

Fire-retardant enhancing PTT/TPEE matrix material and preparation method thereof

Technical field

The present invention relates to technical field of polymer materials, specifically a kind of fire-retardant enhancing PTT/TPEE matrix material and preparation method thereof.

Background technology

Poly(Trimethylene Terephthalate) (PTT), as a kind of new polyester macromolecular material of excellent combination property, has been widely used in the fields such as fiber, film, engineering plastics at present, but is used alone PTT and there is the problems such as flame retardant resistance is bad, intensity 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.

Summary of the invention

The object of the present invention is to provide fire-retardant enhancing PTT/TPEE matrix material that a kind of modified effect is good, cost is low and preparation method thereof.

The technical solution adopted for the present invention to solve the technical problems is: fire-retardant enhancing PTT/TPEE matrix material, its component by mass percent proportioning is: PTT 45% ~ 85%, TPEE 5% ~ 25%, toughener 5% ~ 15%, halogen-free flame retardants 4% ~ 10%, compatilizer 2% ~ 4%, antiager 0.5% ~ 2%, oxidation inhibitor 0.1% ~ 0.5%, lubricant 0.1% ~ 1%.
