A kind of molecular sieve coated aluminum foil and preparation method thereof

Abstract

The invention relates to aluminum foil with a molecular sieve coating and a preparation method of the aluminum foil. The aluminum foil comprises an aluminum substrate and a molecular sieve coating, wherein at least one side of the aluminum substrate is provided with the molecular sieve coating, the aluminum substrate is 0.05-0.5mm thick, and the molecular sieve coating is 4-15mu m thick. The molecular sieve coating contains a molecular sieve and waterborne acrylic resin. The molecular sieve is selected from an activated molecular sieve produced by Shanghai Jiuzhou Chemicals Co., Ltd.. The invention also relates to a preparation method of the aluminum foil with the molecular sieve coating. The preparation method comprises the following steps of firstly, carrying out water treatment on powder of the molecular sieve, and placing the powder of the molecular sieve into ionized water to form a mother solution; secondly, uniformly mixing the mother solution obtained in the first step with waterborne acrylic resin to form a mixed solution; and thirdly, coating and curing, namely cleaning and degreasing the surface of the aluminum substrate before coating, uniformly coating the mixed solution obtained in the second step on the aluminum substrate, and then, drying and curing. The aluminum foil with the molecular sieve coating is strong in adhesive force and adsorption capacity and high in heat exchange energy efficiency.

Description

technical field [0001] The invention relates to the field of coated aluminum foil materials, in particular to a molecular sieve coated aluminum foil and a preparation method thereof. Background technique [0002] Aluminum is widely used due to its low density, good thermal conductivity, easy processing, odorless, environmental protection and low price. [0003] With the development of our country's economy and the continuous improvement of people's living standards, the requirements for ambient air quality are also constantly increasing. In order to solve the problem of air quality degradation caused by long-term use of air conditioners in relatively closed environments in large public places, it is wasteful to open windows for ventilation. For the energy problem, an energy-saving ventilation system is being developed and utilized. On the runner of the ventilation system, molecular sieve materials are used to form a hollow skeleton structure to absorb water molecules in the ...

[0003] With the development of our country's economy and the continuous improvement of people's living standards, the requirements for ambient air quality are also constantly increasing. In order to solve the problem of air quality degradation caused by long-term use of air conditioners in relatively closed environments in large public places, it is wasteful to open windows for ventilation. For the energy problem, an energy-saving ventilation system is being developed and utilized. On the runner of the ventilation system, molecular sieve materials are used to form a hollow skeleton structure to absorb water molecules in the air to keep warm, save energy and purify the air. It has been widely recognized , but the molecular sieve material adhered to the aluminum runner in the prior art has poor adhesion, low moisture absorption, and poor durability.
