Composite high-molecular material film and preparation method thereof

Abstract

The invention provides a composite high-molecular material film and a preparation method thereof, the composite high-molecular material film comprises a heat conduction micropore base material arranged on a bottom layer, the heat conduction micropore base material is coated with a high-molecular polymer coating, a functional auxiliary agent is arranged in the high-molecular polymer coating, and the functional auxiliary agent at least comprises a negative oxygen ion functional auxiliary agent; and the high-molecular polymer coating is of a coating structure capable of blocking a gas and being selectively permeable for water molecules. The composite high-molecular material film can be applied to a fresh air system, can conduct heat, blocks a gas and is permeable for water molecules, exchangeof sensible heat and latent heat can be achieved, the problems that a traditional exchange paper core cannot be washed with water, goes mouldy and the like are solved, and the problems that an exchange aluminum core cannot recover latent heat, is high in cost, and the like are also solved. The composite high-molecular material film at least contains a negative oxygen ion functional additive, cangenerate negative oxygen ions, decomposes and eliminates formaldehyde, benzene and the like in the air, neutralizes dust particles, destroys bacteria, pathogenic bacteria and mould molecules, comprehensively purifies the air, improves the indoor negative oxygen ion concentration, and protects the human body.

Description

【Technical field】 [0001] The invention relates to the technical field of air exchange, in particular to a composite polymer material membrane and a preparation method thereof. 【Background technique】 [0002] With the rapid development of society and the improvement of people's living standards, the surrounding living environment has been severely damaged, and the air quality has been seriously reduced. In order to change the indoor air quality, air purifiers and fresh air systems have been developed. The fresh air system introduces fresh outdoor air into the room after filtration and purification, and exhausts indoor polluted air to the outside, completing the effective circulation of indoor and outdoor air to ensure fresh and comfortable indoor air. [0003] Negative ions are negatively charged oxygen ions of small particle size produced by air through natural action. Negative ions in the air are collectively referred to as "negative oxygen ions" and are colorless and odorl...

AI Technical Summary

Problems solved by technology

Aluminum pellets are only limited to "sensible heat" exchange. Because the humidity cannot be exchanged, "latent heat" cannot be exchanged. The aluminum material also leads to high costs, and the metal material increases the weight of the product; the paper pellets pass through the moisture and moisture in the air. After the dust is corroded, the strength will drop sharply or even be damaged, and the vents will be blocked and cannot be cleaned, resulting in poor ventilation and dehumidification effects, and moreover, it is easy to mold and breed bacteria, leading to secondary pollution

These will result in low heat transfer efficiency, shortened service life, frequent replacement, and virtually increased use costs

The exchange membrane used in the traditional fresh air system cannot decompose harmful gases in the air such as formaldehyde and benzene, let alone release negative oxygen ions
