Abstract

The invention discloses a flame retardant blending modified polytrimethylene terephthalate composition. The composition comprises the following ingredients, by weight, 75%-90% of PTT, 5%-15% of flame retardants, 2%-4% of polyethylene glycol, 0.1%-1% of polytetrafluoroethylene, 0.5%-1% of phenyl glycidyl ether, 0.1%-0.5% of anti-oxidants and 0.1%-1% of lubricants. The flame retardant is a composite phosphorus-based halogen-free flame retardant composed of bisphenol-A bis (diphenyl phosphate), triphenyl phosphate and ammonium polyphosphate with a weight ratio of 4:3:3 through mixing. The beneficial effects are that the composition has excellent flame retardation performance and processing performance, te flame retardation effect can be kept long, no halogen, smoke inhibition and no droplet are achieved, the UL94V-0 level performance requirements can be met, the cost is low, the preparation technology is simple, operation is easy, and popularization and application are convenient.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a flame retardant blended modified poly(trimethylene terephthalate) composition. Background technique [0002] Polytrimethylene terephthalate (PTT), as a new type of polyester polymer material with excellent comprehensive properties, has been widely used in the fields of fibers, monofilaments, polyester dyeing agents, films, thermoplastic engineering plastics and non-woven fabrics. , especially in the field of engineering plastics, PTT has both the high performance of PET and the ease of processing of PBT, and its price is much lower than that of PBT, so it has good practical value. However, PTT, like other engineering plastics, has the disadvantage of poor flame retardancy, which will greatly limit the application range of PTT. In order to meet the fire safety requirements of PTT in practical applications, it is usually necessary to add flame retardants for modificati...
