Fully biodegradable anti-static film for electric appliance packaging and preparation method thereof

Abstract

The invention relates to a fully biodegradable antistatic film for electric appliance packaging and a preparation method thereof, the fully biodegradable antistatic film is prepared by blowing a biodegradable master batch, the biodegradable master batch comprises a main material and an auxiliary material, wherein the main material comprises the following raw materials in percentage by weight: 25-30% of polypropylene carbonate resin, 44-72% of polybutylene-terephthalate adipate, 2-5% of polyethylene glycol succinate and ethylene glycol terephthalate, 1-3% of polylactic acid and 0-18% of talcumpowder; and the auxiliary material comprises the following raw materials in percentage by mass: 0.3-1.3 percent of antibacterial powder, 1.1-2 percent of antifogging agent, 2-4 percent of beewax, 3-4percent of inorganic filler and 25-40 percent of additive. The prepared environment-friendly anti-static film has high tearing strength and high tensile strength, has good stability and high barrier property in a high-temperature and high-humidity environment, does not deform such as warping and wrinkling, and has light transmittance of 94.1% or above and an anti-static value of 108-1012 ohms.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a fully biodegradable antistatic film for electrical packaging and a preparation method thereof. Background technique [0002] Static electricity is an objective natural phenomenon that can be produced in various ways, such as contact, friction, induction between electrical appliances, etc. Static electricity is characterized by long-term accumulation, high voltage, low power, low current and short action time. The action of the human body or the contact, separation, friction or induction with other objects can generate thousands of volts or even tens of thousands of volts of static electricity. [0003] Anti-static film is a stretch film used to prevent static electricity from friction, and is widely used in packaging films for electronics, electrical appliances, and power transmission and transformation equipment. In the development and manufacturing pr...

Problems solved by technology

Static electricity often causes the operation of electronic and electrical products to be unstable or even damaged. At the same time, in the actual production and transportation process, the performance of electronic products will be affected by the storage or transportation environment, such as the surrounding environment with high humidity and high heat, which is easy to damage the packaging of electronic products. Cause damage, severe cases rot, and then cause serious damage to electronic products, so the packaging should shield dust and moisture, and have high temperature resistance and corrosion resistance, so that the packaged electronic products can be transported without being affected by the environment
