specific Embodiment approach

[0020] figure 1 and figure 2 Show the specific embodiment of a kind of breathable ultra-lubricating film of the present invention: this air-permeable super-lubricating film comprises lubricating surface layer 1, film base layer 2 and adhesive layer 3, and film base layer 2 and adhesive layer 3 are densely packed with a large amount of penetration The hole 5, the diameter of the permeable hole 5 is nanoscale, and has waterproof and air-permeable functions.

[0021] combine figure 1 and figure 2 , the lubricating surface layer 1 is a lubricating surface layer formed by preparing a micro-nano composite structure on the surface of the film base layer by physical and chemical methods, then performing hydrophobic treatment, and finally injecting lubricating liquid. The film base layer 2 has the characteristics of good light transmission, good wear resistance, good mechanical properties and the like. The adhesive layer 3 is polyurethane adhesive, which has good bonding effect a...

Abstract

The invention discloses a super-lubricating film with air permeability. The super-lubricating film comprises a super-lubricating film layer, a thin film base layer and a bonding layer, wherein the super-lubricating film layer is a lubricating surface layer formed by preparing a micro-nano structure on the surface of the thin film base layer through a physical or chemical method, then carrying outhydrophobization treatment, and finally injecting lubricating liquid, and nano-sized permeating holes are formed in the thin film base layer and the bonding layer. According to the super-lubricating film, the same film has dual functions of air permeability and super lubrication. At the same time, according to the super-lubricating film, the air permeability degree can be changed by changing the size of the permeating holes, the lubricating property can be changed by changing the nanostructure on the surface of the thin film base layer, so that the application range of the thin film is expanded to various fields such as ice resistance, fog prevention, oil pollution prevention, pollution prevention, medical treatment and 3D printing.

Description

technical field [0001] The invention relates to the field of preparation of super lubricating films, in particular to a breathable super lubricating film. Background technique [0002] DLP laser molding technology is a kind of 3D printing technology. It is a molding technology that uses high-resolution digital light processor (DLP) projectors to irradiate and cure liquid photopolymers. It uses photosensitive resin as printing materials and has fast printing speed. , high molding precision, high printing resolution, and smooth surface of molded parts, which can be compared with injection molded parts. [0003] However, during the printing process of DLP, the working platform needs to move up and down continuously to separate the cured molded parts from the transparent film at the bottom of the resin tank, and the resin in the resin tank refills the bottom. However, during this process, the cured resin layer and the transparent film are torn, and this happens repeatedly as th...
