Abstract

The invention discloses a flame-retardant polyester material, a preparation method thereof, a granule and a fiber product. An o-hydroxybenzophenone derivative, acid anhydride, 2-hydroxyethyl isocyanurate, chloroethanol, terephthalic acid and ethylene glycol are used as raw materials, the defect that traditional polyester is inflammable is overcome, and reaction steps are simple and are easy to operate; 2-hydroxyethyl isocyanurate is adopted as one of the raw materials, so that the reaction activity of -OH and-NH2 is high, the reaction flexibility is high, the nitrogen content is high, and theflame retardance of the material is outstanding; the o-hydroxybenzophenone derivative is used as one of the raw materials, the o-hydroxybenzophenone derivative has an ultraviolet absorption effect andcan be used as a light stabilizer, para-hydroxyl groups in the structure can be used as reaction points for esterification, and the contained benzene ring structure is similar to a polyester structure, so good compatibility and facilitation of wide promotion and application are achieved.

Description

technical field [0001] The invention relates to the technical field of polyester materials, in particular to a flame-retardant polyester material, a preparation method thereof, pellets and fiber products. Background technique [0002] Conventional polyester fibers are single-functional and flammable, which can no longer meet the needs of domestic and foreign markets for product diversification and functionalization. Endowing conventional chemical fibers with new functions is one of the key points and hotspots in the field of new chemical fiber materials research. The flame retardancy of fiber is one of the hotspots that people pay attention to at present. Most of the flame retardant properties of textiles on the market are improved by post-additive additives. The product obtained in this way has the disadvantages of being not wear-resistant and washable, and most of the flame retardants used are halogen-based flame retardants, which are harmful to human health and the envir...
