Abstract
(EN) A halogen-free flame-retardant reinforced PET composite material, comprising the following raw materials in parts by weight: 70-80 parts of PET, 20-30 parts of a toughening agent, 15-20 parts of a modified halogen-free flame retardant, 3-8 parts of a modified flame-retardant synergist, 5-10 parts of modified carbon fibers, 0.1-0.5 part of an antioxidant, 0.2-1 part of a lubricant, and 0.1-0.5 part of an anti-hydrolysis agent. The modified halogen-free flame retardant is a compound of melamine phosphate and an organic carbon source; the modified flame-retardant synergist is PGMA graft modified montmorillonite; the modified carbon fibers are carbon fibers subjected to an oxidation treatment. Also disclosed is a preparation method for the halogen-free flame-retardant reinforced PET composite material. The preparation method is simple and convenient and is easy to implement.
(FR) Matériau composite de PET renforcé ignifugeant et sans halogène, comprenant les matières premières suivantes, en parties en poids : 70 à 80 parties de PET, 20 à 30 parties d’un agent de trempage, 15 à 20 parties d'un ignifugeant sans halogène modifié, 3 à 8 parties d'un synergiste ignifugeant modifié, 5 à 10 parties de fibres de carbone modifiées, 0,1 à 0,5 partie d'un anti-oxydant, 0,2 à 1 partie d'un lubrifiant et 0,1 à 0,5 partie d'un agent anti-hydrolyse. L'ignifugeant sans halogène modifié est un composé de phosphate de mélamine et d'une source de carbone organique ; le synergiste ignifugeant modifié est de la montmorillonite modifiée par greffage de PGMA ; les fibres de carbone modifiées sont des fibres de carbone soumises à un traitement d'oxydation. Un procédé de préparation d'un matériau composite de PET renforcé ignifugeant sans halogène, est également divulgué. Le procédé de préparation est simple et facile à mettre en œuvre.
