Abstract
The invention discloses a varicosity Teflon film paster with patterns on the surface and a manufacturing method thereof. The paster comprises a varicosity Teflon micropore film, a pattern layer, a water and oil repellent finishing agent layer, a pressure-sensitive rubber layer and a PE film carrier band layer. The manufacturing method comprises the steps of pressing the pattern layer on one surface of the varicosity Teflon micropore film, coating the outer surface of the pattern layer with a water and oil repellent finishing agent, attaching the pressure-sensitive rubber layer to the other surface of the varicosity Teflon micropore film, and attaching the PE film carrier band layer to the pressure-sensitive rubber layer; enabling the micropore film surface to face downwards, punching a positioning hole and automatically semi-cutting to the micropore film, removing a waste rubber layer, enabling the micropore film surface to face upwards, detecting the positioning hole at a photoelectric sensor, and automatically semi-cutting the periphery of the micropore film to form patterns. A pollutant rolls off from the surface of the paster due to a self cleaning capacity similar to that of a lotus leaf, air and water vapor permeability is kept, and a particle pollutant can easily fall off due to the surface pattern layer, and does not easily block a ventilation area of the micropore film.
Description
Technical field
The present invention relates to film field, particularly relate to the dapple eptfe membrane paster of a kind of surperficial tool and manufacture method thereof.
Background technology
Car light forms cross-ventilation by the upper diverse location air-vent of light fixture, in lamp, steam raises with the temperature in lamp and discharges outside lamp from the air-vent of upper position, the air-vent of upper/lower positions constantly supplements lamp outer air, thus reduces the ambiguous phenomenon generation of the scattering of steam to light.
In many big and medium-sized cities, the quantity reality of automobile " overload ".The environmental pollution that the waste gas of motor vehicle emission causes.Vehicle exhaust major pollutants are hydrocarbon, oxynitrides, carbon monoxide, sulfur dioxide, lead-containing compounds, Benzpyrene and solid particulate matter etc., in haze weather and overcast and rainy, these pollutants can stick in the body surface of the not water and oil repellant of car light, form dirt, when these oiliness contaminant particles are deposited on the microporous membrane surface of not water and oil repellant, the microporous membrane surface of water and oil repellant does not have self-cleaning ability, with the passing of time the air-locked blanket layer of one deck is defined, the permeability of the microporous membrane of not water and oil repellant is had a strong impact on or airtight, car light convection current of breathing freely is made to regulate the ability of car light humidity greatly to reduce.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the dapple eptfe membrane paster of a kind of surperficial tool and manufacture method thereof, the self-cleaning ability with similar lotus leaf makes pollutant tumble from film paster surface, keep the ability of air-moisture-permeable, the flower-pattern layer on surface is both attractive in appearance, particulate contaminants can be made again more easily to drop, the not easily ventilation area of blocking microporous film.
