Environment-friendly filter membrane

Abstract

The invention relates to an environment-friendly filter membrane, which is composed of the following raw materials in parts by mass: 10-22 parts of polylactic acid fiber, 10-26 parts of polyvinyl alcohol, 10-20 parts of polypropylene, and 24-32 parts of polyhydroxyalkanoate 10-60 parts, 10-60 parts of solvent, 6-16 parts of antibacterial agent and 6-10 parts of additive; wherein, said antibacterial agent is formed by mixing chitin and potassium sorbate, and the mass ratio of chitin and potassium sorbate is 1:1.7~2.1. The advantage of the present invention is that: polylactic acid fiber is used in the formula of the present invention to prepare the filter membrane, which can make the filter membrane have excellent heat resistance, is not easy to deform under high temperature environment, avoids clogging of the pore structure of the filter membrane, and greatly Improve the heating or cooling effect of the air conditioner; and through the synergistic effect of each component, the filter membrane has long-term antibacterial and antibacterial ability, plays a self-cleaning role, and uses environmentally friendly polyhydroxyester fatty materials , improve the environmental performance of the filter membrane.

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] An environmentally friendly filter membrane. 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 an automobile environmental-friendly filter membrane and its preparation method, wherein the preparation method in...

Problems solved by technology

It solves the problem that the current filter membrane has poor mechanical properties and chemical stability, and is easily deformed under high-temperature ring conditions, causing the pore structure inside the filter membrane to collapse, which is likely to cause blockage of the filter membrane pore structure and affect the heating or cooling effect of the air conditioner Problems; but this kind of automotive environmental protection filter membrane has the following disadvantages: During the filtration process of the filter membrane, 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: 1. This 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; 2. . Some raw materials selected in the formula will produce a large amount of carbon dioxide during production, causing environmental pollution
