Problems solved by technology

However, the filtering effect of the filter is limited and the wind resistance is increased, which affects the heat transfer effect
3. The full heat exchange mode is adopted, and the air intake adopts outdoor fresh air to avoid the heat exchanger from being exposed to oily fumes, and this method will significantly increase the volume of the air conditioner, which is not conducive to installation in the limited space of the kitchen

preparation example Construction

[0077] According to an embodiment of the present invention, the method for preparing a coated aluminum foil includes the following steps: coating paint on at least one surface of an aluminum foil substrate to form a functional coating to obtain a coated aluminum foil.

[0078] According to an embodiment of the present invention, when the functional coating contains a hydrophilic layer and an anti-corrosion layer, when preparing the coated aluminum foil, the anti-corrosion layer coating is first primed to form an anti-corrosion layer, and then the hydrophilic layer coating is topcoated to form a hydrophilic layer. layer to produce a coated aluminum foil. In some embodiments of the present invention, the preparation method of the coated aluminum foil comprises the following steps: 1) coating an anti-corrosion coating on at least one surface of the aluminum foil substrate, curing to form an anti-corrosion layer; The surface away from the aluminum foil base material is coated with...

Abstract

The invention discloses a coated aluminum foil as well as a preparation method and application thereof. The coated aluminum foil provided by the invention comprises an aluminum foil base material and a functional coating, wherein the functional coating is arranged on at least one surface of the aluminum foil base material; the functional coating at least comprises a hydrophilic layer; the ratio of the single-side coating amount forming the hydrophilic layer to the single-side coating amount forming the functional coating is greater than or equal to 35%. The coating aluminum foil provided by the invention can prevent the performance of the hydrophilic coating from being reduced along with time consumption, so that the hydrophilic effect and the long-term effect of the hydrophilic performance of the coating aluminum foil are improved, and the dirt-removing power is improved.

Description

technical field [0001] The invention relates to the field of coating film materials, in particular to coated aluminum foil and its preparation method and application. Background technique [0002] In hot summer weather, the kitchen temperature can reach above 40°C, and it is necessary to install an air conditioner to enhance the cooking experience. However, edible oil and food undergo thermal oxidation decomposition under high temperature conditions, and secondary reactions can occur between the decomposition products. The use of heat exchangers The hydrophilic coating is good for stain removal, but oil stains adhere to the surface of the heat exchanger, which will reduce the hydrophilicity of the fins, affect the heat exchange efficiency, and produce odors under the action of microorganisms. [0003] The current improvement schemes mainly include: 1. Increase the oil fume sensor to monitor the oil fume concentration. Using this method will result in higher costs and only m...
