Embodiment Construction

[0035] The present invention will now be described in further detail with reference to the embodiments.

[0036] The antibacterial and antistatic polyester film is prepared by the following method: Weigh the components in proportion, mix them thoroughly, heat and dry them, and then add them to the melt extrusion equipment for extrusion, and then stretch, heat-set, and cool. , and winding to obtain an antibacterial and antistatic polyester film.

[0037] Among them, the extrusion temperature is 230-300 ℃; the stretching is biaxial stretching, the stretching temperature of longitudinal stretching is 80-110 ℃, the stretching ratio is 2.5-4.5 times, and the stretching temperature of transverse stretching is 110- 140℃, the stretching ratio is 2.5-4.5 times; the heat setting temperature is 230-250℃, and the cooling temperature is lower than 80℃.

[0038] The components and the amounts of the components in Examples 1-3 and Comparative Examples 1-3 are shown in Table 1.

Abstract

The invention belongs to the technical field of polyester films, and in particular relates to an antibacterial and antistatic polyester film, which is characterized by comprising the following components in parts by weight: 50-70 parts of polyester, 1-4 parts of lubricant, light stabilizer 0.1-2 parts, antioxidant 0.1-1 part, curing agent 0.05-0.1 part. In the present invention, terephthalic acid, ethylene glycol and antibacterial and antistatic components are used as raw materials, and the polyester component is obtained by polymerization, and a structure with antibacterial and antistatic effects is introduced into the polyester component by means of polymerization, and no additional small Molecular antibacterial agent and antistatic agent to avoid adverse effects on the tensile properties and mechanical properties of polyester film; the antibacterial and antistatic component of the present invention provides good antibacterial effect through the triphenylphosphine structure, in addition, antibacterial and antistatic The component contains ionic structure, which has antistatic effect. The conductive effect of ions can make static electricity leak in time and avoid charge accumulation.

Description

technical field [0001] The invention belongs to the technical field of polyester films, in particular to an antibacterial and antistatic polyester film. Background technique [0002] Polyester film (PET) is made of polyethylene terephthalate as a raw material, made into a thick sheet by extrusion method, and then made into a film material by biaxial stretching. Polyester film is usually colorless, transparent and glossy film (additive particles can be added to make it have color), excellent mechanical properties, high rigidity, hardness and toughness, puncture resistance, friction resistance, high temperature and low temperature resistance, chemical resistance It has good drug resistance, oil resistance, air tightness and fragrance retention, and is one of the commonly used barrier composite film substrates. Polyester film is widely used in various fields such as packaging materials, film or film substrates, electrical insulating materials, and flexible printed circuit boar...
