Abstract

The invention relates to a titanium-containing polyester slice applied to a polyester film. The titanium-containing polyester slice applied to the polyester film is characterized in that the titanium-containing polyester slice comprises the following raw materials by mass percentage: 1 to 3 percent of titanium catalyst, 1 to 3 percent of PEN (polyethylene naphthalate) particle, 10 to 20 percent of regenerated PET (polyethylene terephthalate) particle and balance of PET particle, wherein the titanium catalyst is of a kernel-core structure; a core layer is a titanium-carried coconut shell charcoal material and a kernel layer is polyethylene glycol. The core layer, i.e., the titanium-carried coconut shell charcoal is wrapped inside the kernel layer, i.e., the polyethylene glycol through high-speed grinding, so grinding dispersion and surface covering are simultaneously performed, and not only can the coconut shell charcoal ground during grinding be prevented from being agglomerated, but also the influence on the catalytic effect of the titanium material after the surface covering of the polyethylene glycol is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of polyester films, in particular to a titanium-containing polyester chip applied to polyester films. 【Background technique】 [0002] Polyester film is a film material made of polyethylene terephthalate as a raw material, which is made into a thick sheet by extrusion and then biaxially stretched. It is a colorless, transparent, glossy film with excellent mechanical properties, high rigidity, hardness and toughness, puncture resistance, friction resistance, high and low temperature resistance, chemical resistance, oil resistance, air tightness and fragrance retention. Good, it is one of the commonly used barrier composite film substrates. However, the price of polyester film is relatively high, and the general thickness is 12mm. It is often used as the outer material of retort packaging, and has good printability. Its characteristics are: [0003] (1) High mechanical strength, its tensile strength is 5 t...
