Abstract

The invention relates to the technical field of function modification of plastics, in particular to an anti-conglutinant master batch and a PETG thin film and a preparation method thereof. The anti-conglutinant master batch is prepared from the raw materials such as substrate resin, anti-conglutinant microspheres, an antioxidant, a light stabilizer and an ultraviolet light absorbing agent. Polyacrylonitrile carbon fiber which has good compatibility with PETG resin and has appropriate strength serves as a carrier of a nano anti-conglutinat agent, the problems that the nano anti-conglutinant agent is prone to agglomerating, hard to disperse and not compatible with the substrate resin are solved, meanwhile, the nano anti-conglutinant agent can make the polyacrylonitrile carbon fiber have theuneven surface due to the size effect of the nano anti-conglutinant agent, accordingly the roughness of the thin film is improved, however, the hardness of salient points of the thin film cannot be super high, so the thin film is not easy to damage; in addition, the polyacrylonitrile carbon fiber can serve as an enhancing filling material to enhance the mechanical properties, such as tensile strength and impact resistance, of the master batch.

Description

technical field [0001] The invention relates to the technical field of functional modification of plastics, in particular to an anti-blocking masterbatch, a PETG film and a preparation method. Background technique [0002] Modified polyester PETG is synthesized by introducing 1,4-cyclohexanedimethanol monomer in the polymerization process and modifying PET by copolymerization. Compared with PET, PETG has a significantly lower crystallization rate, wider molding range, higher glass transition temperature, superior optical properties, good printability, better mechanical and processing properties, and has been applied to plates, sheets, and shrink films. , bottles, profiled materials and other products. Among them, heat shrinkable packaging film is one of the important uses. [0003] However, PETG has a common problem with general films - easy to stick. In the prior art, anti-blocking agents are generally directly added to PETG resin for blending modification to solve this ...
