Abstract
The invention discloses a low-smoke halogen-free flame-retardant PTT polyester and a preparation method therefor. The low-smoke halogen-free flame-retardant PTT polyester comprises the following ingredients, by weight, 75%-90% of PTT, 5%-15% of halogen-free flame retardants, 2%-5% of aliphatic polyethers, 0.5%-3% of low smoking promoter, 0.1%-0.5% of anti-oxidants and 0.1%-1% of lubricants. The halogen-free flame retardants are a mixture of halogen-free phosphorus-based flame retardant bisphenol-A bis (diphenyl phosphate) and a silicon-based flame retardant dimethyl silicone polymer with a weight ratio of 4:1. The low smoking promoter is one of nanosilicon dioxide, nano-zinc oxide, nanometer titanium dioxide and nanometer aluminum oxide.

Description
Technical field
The present invention relates to technical field of polymer materials, specifically a kind of low-smoke non-halogen flame-retardant PTT polyester and preparation method thereof.
Background technology
Poly(Trimethylene Terephthalate) (PTT) gathers naphthalate (PET) and a kind of new polyester macromolecular material having development prospect of new research and development after the polybutylene terephthalate seventies (PBT) continue the 1950's, due to its excellent combination property, be considered to a kind of new polyester material that 21 century gets a good chance of.The fields such as fiber, monofilament, polyester dyeing agent, film, thermoplastic engineering plastic and non-woven fabrics are widely used at present, especially in engineering plastics field, PTT has the high-performance of PET and the workability of PBT simultaneously, and its price is much lower compared with PBT, bring sizable impact can to undoubtedly general engineering plastic market.Then, unmodified PTT is the same with other general-purpose plastics, and still there is easy firing, defect that notch sensitivity is large, this will greatly limit the expansion of PTT range of application in every field, in order to meet PTT fire safety demands in actual applications, usually needing to add fire retardant and carrying out modification.Add halogen flame effective, but do not meet environmental requirement, substituted by halogen-free flame retardants gradually, and also some halogen-free flame retardants amount of being fuming when burning is large, still can cause great threat to the life security of people and living environment.
Summary of the invention
The object of the present invention is to provide low-smoke non-halogen flame-retardant PTT polyester that a kind of good flame resistance, intensity are high and cost is low and preparation method thereof.

Described aliphatic polyether be molecular weight 600 ~ 5000 polyoxyethylene glycol.
Described low promotor of being fuming is the one in nano silicon, nano zine oxide, nano titanium oxide, nano-aluminium oxide.
Described oxidation inhibitor is the Hinered phenols antioxidant 1010 or 1076 of mass ratio 1:1 and the compound of phosphite ester kind antioxidant 168.
Described lubricant is pentaerythritol stearate.
The preparation method of above-mentioned low-smoke non-halogen flame-retardant PTT polyester is: take each component by weight ratio, and add respectively in high-speed mixer, make to stir 3 ~ 5 minutes together, evenly rear discharging to be mixed adds in twin screw extruder, extrude through melting mixing at 220 DEG C ~ 250 DEG C temperature, cooling granulation, drying, obtain low-smoke non-halogen flame-retardant PTT polyester of the present invention.
The invention has the beneficial effects as follows, the present invention has good flame retardant properties and mechanical property, and meets the low cigarette of halogen-free flameproof, safety, environmental protection and UL94 V-0 level flame-retardancy requirements, and processing fluidity is good, cost is low, and preparation technology is simple and be easy to manipulation, easy to utilize.
