Problems solved by technology

However, spraying a superhydrophobic coating on the surface of the bottle cap to achieve superhydrophobic properties usually requires the introduction of micro-nano rough structures and low surface energy substances on the surface of the substrate. Currently, spraying is used to introduce micro-nano rough structures and low surface energy substances. The preparation process is very complicated, and the preparation process is very cumbersome, and the substances used in the coating are usually not food-grade substances. Long-term use poses a potential threat to human health, and the prepared coating has poor durability and is easy to fall off.

Embodiment 1

[0022] First, the aluminum sheet is polished, and then the polished aluminum sheet is ultrasonically cleaned with ethanol, and dried at room temperature.

[0023] Use a sandblasting machine to treat the surface of the cleaned aluminum sheet for 3 minutes. Laminate a PP plastic plate with a thickness of 1mm on top of the sandblasted aluminum sheet and put it on the embossing machine for embossing. The printing temperature is 200°C, the pressure is 12kPa, and the printing is carried out for 10 minutes. After that, the PP plastic plate after the printing treatment is demolded to obtain a PP plastic film, and the contact angle of the surface of the PP plastic film is tested.

Embodiment 2

[0025] First, the aluminum sheet is polished, and then the polished aluminum sheet is ultrasonically cleaned with ethanol, and dried at room temperature.

[0026] The surface of the aluminum sheet is treated with a sandblasting machine, and the processing time is 3 minutes. A PE plastic plate with a thickness of 1mm is laminated on the top of the sandblasted aluminum sheet, and placed on the embossing machine for embossing treatment. The embossing temperature is After embossing for 10 minutes at 150°C and a pressure of 12kPa, the embossed PE plastic plate was demolded to obtain a PE plastic film, and the contact angle on the surface of the PE plastic film was tested.

Embodiment 3

[0028] First, the aluminum sheet is polished, and then the polished aluminum sheet is ultrasonically cleaned with ethanol, and dried at room temperature.

[0029] Use a sandblasting machine to process the surface of the cleaned aluminum sheet for 3 minutes. A PET plastic plate with a thickness of 0.1mm is laminated on top of the sandblasted aluminum sheet and placed on the imprinting machine for embossing. The embossing temperature was 200°C, the pressure was 10kPa, and after 10 minutes of embossing, the embossed PET plastic plate was demolded to obtain a PET plastic film, and the contact angle of the PET plastic film surface was tested.

Abstract

The invention provides a hydrophobic plastic film and a preparation method thereof. The preparation method comprises the following steps of polishing a metal sheet, and cleaning the polished metal sheet; performing sand blasting treatment on the cleaned metal sheet; laminating a plastic plate above the sand-blast metal sheet, and performing stamping treatment; and demolding the stamped plastic plate to obtain the hydrophobic plastic film. The plastic film prepared according to the preparation method has the advantages that the hydrophobicity of the plastic film can be effectively improved, andthe adhesion problem of viscous fluid to the surface of the plastic film is effectively solved.

Description

technical field [0001] The invention relates to hydrophobic materials, more specifically, to a hydrophobic plastic film and a preparation method thereof. Background technique [0002] At present, the method to solve the sticking problem of viscous liquid on the plastic bottle cap is mainly to spray super-hydrophobic coating on the surface of the plastic bottle cap. However, spraying a superhydrophobic coating on the surface of the bottle cap to achieve superhydrophobic properties usually requires the introduction of micro-nano rough structures and low surface energy substances on the surface of the substrate. Currently, spraying is used to introduce micro-nano rough structures and low surface energy substances. The preparation process is very complicated, and the preparation process is very cumbersome, and the substances used in the coating are usually not food-grade substances. Long-term use has potential threats to human health, and the prepared coating has poor durability...
