preparation example Construction

[0013] The invention provides a method for preparing a filter membrane for automobile air conditioners, wherein the preparation method comprises: mixing polyethylene terephthalate, trifluoroacetic acid, dichloromethane and sodium hydroxide to form a mixed liquid M; mix nano-silver oxide and glycerin, and obtain mixed solution N after dispersion; after mixing the mixed solution M and the mixed solution N, the filter membrane is obtained through a spinning device, wherein, relative to 100 parts by weight polyethylene terephthalate, the consumption of trifluoroacetic acid is 40-60 parts by weight, the consumption of dichloromethane is 15-25 parts by weight, the consumption of sodium hydroxide is 50-70 parts by weight, and the consumption of nano-silver oxide The dosage is 1-3 parts by weight, and the dosage of glycerin is 20-35 parts by weight. Through the synergistic effect of various raw materials, the prepared filter membrane has excellent mechanical properties and antibacteri...

Embodiment 1

[0019] 100g polyethylene terephthalate, 45g trifluoroacetic acid, 18g methylene chloride and 55g sodium hydroxide were mixed to form a mixed solution M; 1.5g nano-silver oxide and 25g glycerin were mixed and ultrasonically dispersed (ultrasonic frequency was 2HKz, the time is 2min) to obtain the mixed solution N; after the mixed solution M and the mixed solution N are mixed, the filter membrane A1 is obtained by a spinning device, wherein the average weight molecular weight of polyethylene terephthalate is 8000, the particle size of nano-silver oxide is 10nm.

Embodiment 2

[0021] 100g polyethylene terephthalate, 55g trifluoroacetic acid, 22g methylene chloride and 65g sodium hydroxide were mixed to form a mixed liquid M; 2.5g nano-silver oxide and 30g glycerin were mixed and ultrasonically dispersed (ultrasonic frequency was 5HKz, the time is 5min) to obtain the mixed solution N; after the mixed solution M and the mixed solution N are mixed, the filter membrane A2 is obtained by a spinning device, wherein the average weight molecular weight of polyethylene terephthalate is 12000, the particle size of nano-silver oxide is 30nm.

Abstract

The invention discloses a filter membrane for an automobile air conditioner and a preparation method of the filter membrane, wherein the preparation method comprises the steps of mixing polyethylene glycol terephthalate, trifluoroacetic acid, dichloromethane and sodium hydroxide to form mixed liquor M; mixing nano-silver oxide and glycerol, dispersing to obtain mixed liquor N; mixing the mixed liquor M with the mixed liquor N, and and preparing the filter membrane through a spinning device. The problems that the existing filter membrane is easily broken after being used for a long time, and the bacteriostatic ability is worse are solved.

Description

technical field [0001] The invention relates to an automobile air conditioner accessory, in particular to a filter membrane for an automobile air conditioner and a preparation method thereof. Background technique [0002] With the rapid growth of the automobile industry, the auto parts industry has also developed rapidly. As an important component to improve the comfort of automobiles, automobile air conditioners have been recognized by the majority of automobile manufacturers and consumers. After the car air conditioner is used for a long time, a large amount of dust will accumulate inside it, so it is necessary to install a filter membrane at the air outlet to filter the dust. The current filter membrane is easily broken after long-term use, and at the same time, the antibacterial ability is poor. Contents of the invention [0003] The invention provides a filter membrane for automobile air conditioners, which solves the problems that the current filter membrane is easil...
