Problems solved by technology

However, at present, in the field of air filtration, no such products have entered the market, and they are still in the research and development stage.
[0003] In short, there is currently no effective and practical filter monofilament that can be used for air filters with functions such as antibacterial, mildew-proof, deodorization, anti-fouling self-cleaning, and emission of negative ions, and there is no air filter with these functions. Filter

preparation example Construction

[0039] The preparation method of the photocatalyst antibacterial and mildew-proof anion polypropylene monofilament involved in the present invention, comprises the following steps successively:

[0040] (1) Coupling treatment of photocatalyst, antibacterial and negative ion powder

[0041] According to the weight ratio of photocatalyst powder: antibacterial powder: antimildew powder: negative ion powder=35~45:15~25:4~8:25~35, four kinds of powders are weighed, each kind of powder diameter is between 0.01~10 μm. Put the three powders of photocatalyst, antibacterial and negative ion powder into the mixer and mix them well at room temperature for about 3 minutes. Then measure the coupling agent according to 0.5% to 1.5% of the total amount of the four powders, and then dilute the coupling agent with a coupling agent solvent of the same weight as the coupling agent. Sprinkle the diluted coupling agent evenly on the photocatalyst antibacterial negative ion mixed powder, and stir e...

[0100] (1) Coupling treatment of photocatalyst, antibacterial and negative ion powder

[0101] According to the weight ratio of photocatalyst powder: antibacterial powder: antimildew powder: anion powder=35:15:4:25, four kinds of powders are measured, and the average diameter of the powders is 0.01. Put the three powders of photocatalyst, antibacterial and negative ion into the mixer and stir them well at room temperature for 3 minutes. Then measure the coupling agent by 0.5% of the total amount of the first four powders, and then weigh the liquid paraffin with the same weight as the coupling agent as a solvent to dilute the coupling agent. Sprinkle the diluted coupling agent evenly on the photocatalyst antibacterial anion mixed powder, and stir evenly for 6 minutes. And the measured anti-mildew powder is ready for use

[0122] According to the weight ratio of photocatalyst powder: antibacterial powder: antimildew powder: negative ion powder = 39: 15: 5: 29, four kinds of powders were weighed, and the average diameter of the powders was 10 μm. Put the three powders of photocatalyst, antibacterial and negative ion into the mixer and stir them well at room temperature for 3 minutes. Then measure the coupling agent according to 0.9% of the total amount of the first four powders, and then take liquid paraffin with the same weight as the coupling agent as a solvent to dilute the coupling agent. Sprinkle the coupling agent evenly on the photocatalyst antibacterial anion mixed powder, and stir evenly for 6 minutes. And the measured anti-mildew powder is ready for use

Abstract

The photocatalytic antibacterial moldproof negative ion polypropylene monofilament contains photocatalyst powder, antibacterial powder, moldproof agent powder and negative ion powder in the weight ratio of 35-45 to 15-25 to 4-8 to 25-35 and in the total amount of 3-8 wt% of the polypropylene monofilament, coupler in the amount of 0.5-1.5 wt% of the foregoing four additives, solvent for diluting the coupler in the same amount as the coupler, and dispersant in the amount of 1-3 wt% of the foregoing four additive. The present invention also provides the preparation process and use of the polypropylene monofilament. The polypropylene monofilament is used in weaving air strainer for air filter, and has the functions of resisting bacteria, preventing mildew, deodorizing, self-cleaning, emitting negative ion, etc.

Description

technical field [0001] The invention relates to a functional polypropylene monofilament and its preparation method and use, in particular to a photocatalyst antibacterial and anti-mildew anion polypropylene monofilament and its preparation method, which can be used especially for the air filter in the air filter. Background technique [0002] With the improvement of social living standards, people have higher and higher requirements for the air quality output by air conditioners and air purifiers that are used in large quantities, and the requirements for air filters have also increased. It must not only be able to filter out dust in the air, but also have functions and functions such as antibacterial, mildew-proof, deodorization, anti-fouling self-cleaning, and emission of negative ions. It should be antibacterial, mildew-proof, deodorizing, anti-fouling, self-cleaning, and emit negative ions. However, at present, in the field of air filtration, no such products have enter...
