Abstract
The invention relates to a waterproof ventilated membrane for car light. The waterproof ventilated membrane is formed by compounding of three layered structures and comprises a fabric layer, a waterproof ventilated layer and a bonding layer which is arranged between the above fabric layer and the waterproof ventilated layer and is used for connecting the fabric layer and the waterproof ventilated layer. The invention solves defects existing in the prior art. According to the waterproof ventilated membrane for car light, a fabric material and an expanded polytetrafluoroethylene film undergo compounding, laminated water resistance and oil resistance processing so as to obtain a multifunctional high-molecular material, thus endowing the expanded polytetrafluoroethylene film with better strength, waterproofness, permeability, oleophobic performance, long life, weldability and the like and maintaining internal and external pressure balance. The waterproof ventilated membrane can be used to raise reliability of many automobile parts, including parts of a car light, an engine controller/anti-lock braking system module, a sensor, a connector, an electric car window motor, a fuel system and the like, and is applied in automobile and heavy trucks. Air exchange can be carried out rapidly according to the pressure variation generated by temperature change, and vehicles can be protected from being polluted by water, automobile discharged fluids and dust.
Description
Technical field
The present invention relates to a kind of vehicle component protecting film, particularly a kind of waterproof air-permeable film of car lamp and manufacture method thereof.
Background technology
Along with popularizing of automobile, people are more and more higher for the qualitative performance requirements of automobile, and automobile is when rainwater and high/low temperature weather travel, and many important spare parts of automobile undergo the pollution of rainwater, automobile greasy dirt, dust and other dirt.As car light, connector, baroceptor, electronic unit and hood bottom etc. are exposed to various weather, road conditions all the time and may affect in the environment of road holding.The protection of these important spare parts was very simple in the past, as blocked with common fabric cloth or plastic sheeting, simple protection causes and dabbles, humidity, automobile greasy dirt, mince in road surface, the situations such as dust have impact on vehicle component, reduce the performance of vehicle component, thus affect vehicle mass performance and security performance, temperature fast decline can cause the internal pressure of some parts assemblies to decline, form negative pressure, thus suck pollution thing, increase the fault that knot mist also may cause part, connector, baroceptor, electronic units etc. infiltrate rear oxidation through rainwater and get rusty, lose function gradually, go wrong frequently, add insecurity and the maintenance cost of automobile.
Summary of the invention
The object of this invention is to provide one and overcome above-mentioned shortcoming, permeability is good, the waterproof air-permeable film of car lamp that waterproof effect is good and manufacture method thereof.
The technical scheme realizing the object of the invention is: a kind of waterproof air-permeable film of car lamp, form for three-decker is laminated, there is tissue layer, waterproof ventilative layer and be arranged between such fabric layer with waterproof ventilative layer, for being connected the tack coat of tissue layer and waterproof ventilative layer.
The waterproof ventilative layer of above-mentioned waterproof air-permeable film of car lamp is eptfe film, and such fabric layer is non-woven fabrics.
A manufacture method for waterproof air-permeable film of car lamp, is characterized in that: have following steps:
A, polytetrafluoroethyldispersion dispersion resin are pressed into cylinder blank;
B, by rolling process, cylinder blank to be laminated;
The de-extrusion aid of c, warp, stretching, thermal finalization, finally obtained eptfe film;
D, the process of non-woven fabrics waterproof and oilproof;
E, eptfe film and non-woven fabric compounded, lamination, integral waterproofing, anti-oil processing;
F, detection;
G, rolling packaging.
The steps d of above-mentioned waterproof air-permeable film of car lamp manufacture method adopts following processing step: non-woven fabrics unreels, and unreels speed 0.5 m/min, and---coating fluorochemical monomer CF4 liquid does water-proofing treatment, and---low temperature 35 ~ 45 degree of oven dry make solvent volatilize---to be coated with organic silicon compound liquid and to do---low temperature 35 ~ 45 degree of oven dry make solvent volatilize---rolling of hating oil processing.
The step e of above-mentioned waterproof air-permeable film of car lamp manufacture method adopts following processing step: eptfe film unreels,---surface of eptfe film coating NaOH and diallyl melamine mixed liquor do microporous membrane activation process and---between non-woven fabrics and eptfe film, are coated with and have polar group binding agent that---low temperature 35 ~ 45 degree is dried for eptfe film and non-woven fabric compounded lamination---eptfe film be coated with organic silicon compound liquid do hate oil processing---to unreel speed 0.2 m/min.
Eptfe film in the step of above-mentioned waterproof air-permeable film of car lamp manufacture method and non-woven fabric compounded, laminating temperature are 40 ~ 60 degree.
The present invention has positive effect: the invention solves the defect existed in prior art, what lamp waterproof ventilated membrane obtained after adopting textile material and eptfe film compound, laminated waterproof and grease proofing processing has multi-functional macromolecular material, makes eptfe film be provided with the advantages such as better intensity, water proofing property, gas permeability (internal and external pressure balance), oil repellency, long-life and weldability; Waterproof ventilated membrane can improve the reliability of many automobile components; comprise car light, engine controller (ECU)/anti-lock braking system (ABS) module; sensor; connector; power window motor and fuel system component etc.; be applied in automobile and heavy truck, the pressure that can produce according to temperature change change carries out air exchange rapidly, and protection vehicle is from the pollution of water, automobile discharge opeing and dust.
