Abstract

The invention discloses a core-shell particle toughening PET slipping antibacterial master batch and a preparation method thereof. The core-shell particle toughening PET slipping antibacterial master comprises the following components in percentage by weight: 15%-30% of PET, 20%-40% of talcum powder, 10%-30% of elastomers, 1%-4% of methacrylic acid, 0.5%-2% of diethyl azodiformate, 3%-8% of anti-blocking agents, 5%-20% of slipping agents, 5%-15% of antibacterial agents, 3%-5% of lubricating agents, 0.5%-3% of coupling agents, 0.1%-1% of stabilizing agents and 0.1%-1% of antioxidants. According to the core-shell particle toughening PET slipping antibacterial master batch, the talcum powder is subjected to surface pretreatment and then interacted and subjected to grafting reaction with an elastomer so as to form a core-shell structure which takes the talcum powder as a core and the elastomer as a shell, so that very good synergistic toughening enhanced effect is achieved; in addition, the prepared master batch is applied to a PET film or sheet product and has the advantages of good anti-blocking slipping effect, antibacterium, stability, good processing property and convenience for use.

Description

technical field [0001] The invention relates to a master batch and a preparation method thereof, in particular to a core-shell particle toughened PET smooth and antibacterial master batch and a preparation method thereof. Background technique [0002] Polyethylene terephthalate (PET) is a linear polyester commonly used as a raw material for fibers, extruded film and sheet, blow molding, and more. The polyester film or sheet made of it has good gas barrier properties, elongation and mechanical strength, but poor smoothness and poor impact toughness. At the same time, with the improvement of people's living standards, the demand for antibacterial PET is also increasing. Adding an appropriate amount of antibacterial agent can endow PET with certain antibacterial and bactericidal capabilities. Contents of the invention [0003] The object of the present invention is to provide a core-shell particle toughened PET smooth and antibacterial masterbatch and a preparation method th...
