Embodiment 1
[0032] A method for producing a waterproof breathable film, comprising the following steps:
[0033] A. Using the PET polymer material film as the base material, the polymer material film is irradiated with high-energy charged particles.
[0034] The irradiation power is 2,000-10,000 kilowatts, and the irradiation time is 0.5-200 seconds. The micropore density can be adjusted by adjusting the irradiation energy and irradiation time, and the obtained micropore density ranges from 100,000 to 20 million per square centimeter.
[0035] B. Immerse the irradiated PET polymer material film in a container filled with NaOH solution for etching reaction to obtain a waterproof and breathable film.
[0036] The concentration of NaOH solution is 15-35%, the etching reaction temperature is 70-90 degrees Celsius, the etching time is 0.2-60 minutes, and the obtained micropore diameter is 30 nanometers, which can be adjusted by adjusting the alkali concentration, reaction temperature, and reac...

The invention discloses a waterproof and breathable electric appliance cavity structure which comprises a cavity of an electric appliance. The structure is characterized in that a through hole communicating the inside with the outside of the cavity is formed in a cavity wall, a waterproof and breathable film is covered on the through hole, and air holes preventing liquid water from passing are formed in the waterproof and breathable film. Particles become big after water molecules are condensed to become water drops, and due to action (the water molecules pull and contend against each other) of surface tension of the water drops, the liquid water cannot pass a bore diameter capable of allowing free water molecules to pass in a normal-pressure state, so that the waterproof and breathable film is enabled to have a waterproof and breathable function, waterproofing can be realized, and the problems of ventilating and air pressure balancing between the inside and the outside of the cavity of the electric appliance can be solved.
Description
technical field [0001] The invention relates to a waterproof and breathable electrical cavity structure and a production method of a waterproof and breathable film. Background technique [0002] As a kind of electrical appliances, LED lamps are generally divided into three components: 1. The metal shell is used to accommodate other components, to dissipate heat, to protect other components from water, and to realize secondary light distribution. 2. Power drive: used to ensure the normal operation of the LED illuminant and prolong its life. 3. LED illuminant: it consists of several small chips in a single or integrated package. [0003] The waterproofing of outdoor lights mainly depends on the method of sealing and isolation. Generally, rubber pads at the junction and waterproof glue are used to isolate the interior of the lamp body cavity from the outside world. The lamp is in an unbalanced state of internal and external gas pressure. When the lamp is working, the tempera...
