Abstract

The invention relates to a multifunctional PET (Polyethylene terephthalate) bright master batch. The multifunctional PET bright master batch is characterized by comprising the following components in percentage by weight: 89.5% of PET powder, 10% of fine IPA (isopropylamine), and 0.5% of grafted modified polyfatty acid amide lubricant. The multifunctional PET bright master batch is applied to the PET glass fiber reinforced modified engineering plastics and PET spinning, so that the current and torque during pelletizing can be lowered, and the material melt index is improved. For a product which is injection-molded after being pelletized, a glass fiber exposing phenomenon on the product surface can be effectively prevented, the glossiness of the product surface can be improved, influences on the mechanical performances of the product are not great, and especially, the toughness of the material is improved to a certain extent. Moreover, the brightness, the vividness, the dyeing strength, the wear resistance, the moisture absorption, the antistatic property and the elongation at break for spinning are partially increased, so that the spinnability of the spinning is improved greatly.

Description

technical field [0001] The invention relates to a masterbatch, in particular to a multifunctional bright masterbatch specially used for PET engineering plastic modified materials and cationic polyester filaments. Background technique [0002] Polyethylene terephthalate (PET) is a linear thermoplastic polymer that was first industrialized by Du Pont Company of the United States in 1953. PET can maintain excellent physical and mechanical properties in a wide temperature range. It has excellent fatigue resistance, friction resistance, aging resistance, outstanding electrical insulation, and is stable to most organic solvents and inorganic acids. It has low energy consumption and good processability, so it has been widely used in plastic packaging bottles, films and synthetic fibers. [0003] At present, the development momentum of PET as engineering plastics is good, and its application fields are basically concentrated in industries such as electronics, automobiles and ins...
