Filter membrane for air conditioner

Abstract

The invention relates to a filter membrane for air conditioners, which is composed of, by mass, 8-32 parts of polylactic acid fibers, 8-20 parts of polyvinyl alcohol, 8-16 parts of polypropylene, 20-30 parts of polyhydroxybutyrate-hydroxyvalerate, 15-65 parts of a solvent, 4-12 parts of an anti-bacterial agent, and 6-10 parts of a pore-forming agent. The anti-bacterial agent is prepared by mixing methylene cyanate and potassium sorbate according to the mass ratio of 2.1-2.7:1. The filter membrane includes the polylactic acid fibers, which have high heat resistance and high strength, so that the filter membrane has excellent heat resistance and is not liable to deform at high temperature, and pore structures in the filter membrane are free from being blocked and heating or cooling effects of the air conditioner are greatly improved. Through synergistic effect of the components, the filter membrane has long-lasting anti-bacterial and bacteria-resistant capability and has self-cleaning effect.

Description

technical field [0001] The invention belongs to the technical field of air conditioner preparation, and relates to an air conditioner accessory, in particular to a [0002] A filter membrane for air conditioners. Background technique [0003] If the air conditioner is not used for a long time, a large amount of dust will accumulate in the air outlet duct inside it. Generally, a filter membrane is installed in the air outlet duct to filter the outlet air. The current filter membranes have poor mechanical properties and chemical stability, and are easily deformed in high temperature environments, causing the pore structure inside the filter membrane to collapse, easily causing blockage of the pore structure of the filter membrane, and affecting the heating or cooling effect of the air conditioner. [0004] After retrieval, the patent CN 105330294 A discloses a filter membrane for automobile air conditioners and a preparation method thereof, wherein the preparation method incl...

AI Technical Summary

Problems solved by technology

It solves the problem that the current filter membrane has poor mechanical properties and chemical stability, and is easy to deform under high-temperature ring conditions, causing the pore structure inside the filter membrane to collapse, which is likely to cause blockage of the pore structure of the filter membrane and affect the heating or cooling effect of the air conditioner Problem; but this filter membrane for automotive air conditioners has the following disadvantages: During the filter membrane filtration process, there are often a large number of pathogenic bacteria and viruses in the filter object, and this filter membrane cannot effectively inhibit and retain germs, and the germs will adhere to the filter membrane On the one hand, it will cause the filtration effect of the filter membrane to decrease, and on the other hand, it will cause secondary pollution

However, this antibacterial self-cleaning filter membrane has certain disadvantages: the filter membrane is not heat-resistant and is easily deformed in a high-temperature environment, which may easily cause blockage of the filter membrane pore structure and affect the heating or cooling effect of the air conditioner.
