Hydrophobic oleophobic microporous membrane paster for protection of welded car lamp and manufacturing method thereof

Abstract

The invention discloses a hydrophobic oleophobic microporous membrane paster for protection of a welded car lamp and a manufacturing method thereof. The microporous membrane paster comprises a hydrophobic oleophobic finishing agent, a microporous membrane and a low-viscosity PE adhesive tape, wherein one surface of the microporous membrane is coated with the hydrophobic oleophobic finishing agent, and the low-viscosity PE adhesive tape is adhered on the other surface of the microporous membrane. The manufacturing method comprises the following steps: manufacturing of the microporous membrane; preparation of the hydrophobic oleophobic finishing agent; preparation of a hydrophobic oleophobic microporous membrane: a step of feeding the hydrophobic oleophobic finishing agent in a roller coater, unreeling the microporous membrane, allowing one surface of the microporous membrane and a roller to contact a coating and successively carrying out heating and predrying of the roller, baking and rolling; and process preparation: a step of compounding the other surface of the microporous membrane with the low-viscosity PE adhesive tape, carrying out molding and die cutting, discharging waste leftover materials and successively carrying out inspection, rolling and packaging. The hydrophobic oleophobic microporous membrane paster has self-cleaning capability as a lotus leaf does, a better effect on resistance of pollution by automobile exhaust gas is obtained when the hydrophobic oleophobic microporous membrane paster is used for protection of car lamps, and the hydrophobic oleophobic microporous membrane paster is superior to other protection modes and is an ideal method to overcome environmental load.

Description

technical field [0001] The invention relates to the field of car lamp protection, in particular to a hydrophobic and oil-repellent microporous film patch for welded car lamp protection and a manufacturing method thereof. Background technique [0002] The car light forms air convection through the vent holes at different positions on the lamp. The water vapor in the lamp is discharged from the vent hole at the upper position as the temperature inside the lamp rises, and the vent hole at the lower position continuously replenishes the air outside the lamp, thus reducing water vapor. The phenomenon of steam scattering on the light is blurred. Microporous film is used in the protection of car lights. Although it can make the air in the car lights pass through the film to adjust the pressure balance and achieve non-polluting dust tightness, but when the car is stopped It is impossible to prevent or reduce the water vapor in the environment from entering the housing, and the high ...

AI Technical Summary

Problems solved by technology

The main pollutants of automobile exhaust are hydrocarbons, nitrogen oxides, carbon monoxide, sulfur dioxide, lead-containing compounds, benzopyrene and solid particles, etc. In haze weather and rainy days, these pollutants will stick to the surface of objects that are not water-repellent and oil-repellent , forming dirt, when these oily pollutant particles are deposited on the surface of the non-water and oil-repellent microporous film, the surface of the non-water and oil-repellent microporous film has no self-cleaning ability, and a layer of airtight covering is formed over time The air permeability of the microporous film that is not water-repellent and oil-repellent is seriously affected or airtight, which greatly reduces the ability of the car light to ventilate and convect to adjust the humidity inside the car light
