Description
Technical field
The present invention relates to a kind of car light waterproof ventilative materials of PVDF electrostatic spinning fiber film compound nonwoven cloth.
Background technique
With the aesthetic raising of China's automobile consumption, automotive type appearance is in streamline curved face type, especially Automobile more
Lamp is the eyes of automobile, and mode of appearance is more curving, lively beautiful, outside halogen bulb that car light maturation uses, xenon lamp, is increased newly
LED headlight new technology；The car light of modernization, in order to pursue beauty, shape becomes increasingly complex, and complex-shaped also results in lamp
Temperature difference is generated in shell, therefore after outside air (humidity) entrance, easily generation fog, influence traffic safety.Automobile lamp
Curving and newly-increased LED headlight new technology make automobile lamp clear bulb in offices such as cold place's curved surface, wedge angle transitional regions
The glass bulb inner surface fogging condensation in portion is heavier, and the common scattered mist of following four Foreign Automobile power also can't resolve except the technology of dew
The car light of above-mentioned influence traffic safety coagulates mist condensation trouble.
The bend pipe air hole of European Union's automobile lamp dissipates mist and goes condensation theoretical: inside having sponge dust-proof, also connects in lamp air with lamp
The variation of interior temperature can go out greatly greatly into realize that scattered mist removes condensation in lamp faster, the ventilative car light of bend pipe is using soon
Dust accumulation yellowing and electrical component corrosion in back casing.The condensation fogging of air themperature lower region in shell cannot be solved through using
Problem.
The scattered mist in the U.S. goes condensation theoretical: car light is by, with convection current ventilative outside lamp, establishing a kind of air pressure balance, lamp in lamp
Interior vapor is increased with the temperature in lamp and is discharged outside lamp, and the ventilated membrane pasting method that usable floor area is bigger on shell, which is realized, to be dissipated
Mist removes condensation.Occur to reduce the smudgy phenomenon of scattering of the vapor to light, external environment tide when car light does not work
Humid air can enter in shell.The ventilative film paster quantity that the theory uses is more, cannot solve the lower area of air themperature in shell
The condensation fogging problem in domain.
The scattered mist of Japan goes condensation theoretical: car light is that cross-ventilation is formed by the upper and lower position air hole of lamps and lanterns, in lamp
Vapor increases outside the air hole of upper position discharge lamp with the temperature in lamp, and lamp outer space is continuously replenished in the air hole of lower position
Gas.Occur to reduce the smudgy phenomenon of scattering of the vapor to light, the ventilation plug quantity which uses is more, breathes freely
Measure condensation fogging that is small, but cannot solving the problems, such as air themperature lower region in shell.
Domestic existing lamp inner surface anti-fog coating facture: on the inside of vehicle lamp body after spraying anti-fog coating, through overheating
Drying process is air-dried, hydrophilic group forms antifog coating after film coated surface arrangement.When outside air enters, because high/low temperature influences to generate
When aqueous vapor, water droplet makes moist extension in envelope inner surface, forms smooth moisture film, prevents the generation of fog, light will not be because of fog
And scatter, anti-fog performance shows, and forms reusable functional antifog coating.Micro- water content of the inner casing of some car lights
Height, the vapor that a large amount of micro- moisture content that instantaneous burst discharges within the half an hour that lighting starts are formed, has carried out antifog processing
Envelope inner surface forms that smooth moisture film speed is slow, and trickling becomes water under the influence of the ponding of car light shell bottom is in car light heat
Steam increases the humidity in car light, and a large amount of vapor is still bent at the cold place of automobile lamp clear bulb in shell at this time
The reason of glass bulb inner surface of the part such as face, wedge angle transitional region is because of temperature difference fogging condensation is heavier, and coating glass bulb inner surface rises
Beam divergence caused by mist condenses causes security risk, and the production line investment of car light anti-fog coating needs up to ten million members,
In fact the big difference of producing effects of investment, it is very uneconomical.
Summary of the invention
