Embodiment 1

[0033] Step 1: Add 0.01mol SnCl 4 and 0.02mol Na 2 S was dispersed in 20 mL of [3-MBP][BF with a purity of 0.99 4 ] In the ionic liquid, in order to ensure uniform dispersion, the mixture needs to be ultrasonically treated for 5-10 minutes;

[0034] Step 2: Add 3×3cm uniform non-woven fabric to the above mixture, ultrasonic treatment for 60 minutes, ultrasonic power is 300W;

[0035] Step 3: The above-mentioned non-woven fabric is washed 4-6 times with deionized water and absolute ethanol, and dried at 60° C. for 2-4 hours to obtain the final product.

[0036] Attached SnS prepared as above 2 Non-woven SEM such as figure 1 As shown, it can be seen from the figure that the SnS on the non-woven fabric 2 The particles are extremely fine and clear in shape, well separated and evenly attached to the fiber, SnS 2 The particle size of the particles is 30nm-50nm.

[0037] In order to test the attached SnS prepared in this example 2 For the self-cleaning effect of non-woven fabri...

Embodiment 2

[0040] The difference between this example and Example 1 is that the ionic liquid is 1-ethyl-3-methylimidazolium hexafluorophosphate ionic liquid with a purity of 0.99.

[0041] Attached SnS prepared as above 2 Non-woven SEM such as figure 2 As shown, it can be seen from the figure that the SnS on the non-woven fabric 2 The distribution of particles is uneven, and most of them are concentrated in a certain position on the non-woven fabric, appearing in a pile, and the particle agglomeration phenomenon is serious.

[0042] In order to test the attached SnS prepared in this example 2 For the self-cleaning effect of non-woven fabrics after dipping in red wine, SnS will be attached 2 The non-woven fabric is tested according to the photocatalytic degradation test method.

[0043] The result is: after 30 minutes of ultraviolet irradiation, the colorimetric result is grade 6, and the self-cleaning effect is not good.

Embodiment 3

[0045] The difference between this embodiment and the first embodiment is that the solvent of this embodiment is deionized water.

[0046] In order to test the attached SnS prepared by the method of the present invention 2 The self-cleaning effect of non-woven fabrics on red wine after dipping, will be attached to SnS 2 The non-woven fabric is tested according to the photocatalytic degradation test method.

[0047] The result is: after 30 minutes of ultraviolet irradiation, the colorimetric result is grade 7.

Abstract

The invention relates to a preparation method and application of an attachment SnS2 nonwoven fabric. The method includes the step of attaching SnS2 particles to the nonwoven fabric through an impregnation method with 1-butyl-3-picoline tetrafluoroborate ionic liquid as solvent, wherein particularly, the attachment SnS2 nonwoven fabric is prepared through the impregnation method with SnCl4 and Na2S as raw materials and 1-butyl-3-picoline tetrafluoroborate ionic liquid as solvent, and the obtained attachment SnS2 nonwoven fabric is used for self-cleaning of red wine. According to the preparation method, the ionic liquid with low volatility, high stability, low toxicity and incombustibility is used as solvent, and the purposes of green chemistry are achieved; meanwhile, the preparation method is simple and easy to operate, the obtained attachment SnS2 nonwoven fabric has a good self-cleaning effect under the condition with ultraviolet light, and the special function that the nonwoven fabric can resist ultraviolet light and conduct self-cleaning at the same time is achieved.

Description

technical field [0001] The invention belongs to the field of materials science, in particular to a SnS attached 2 Preparation method of non-woven fabric and its application. Background technique [0002] Non-woven fabrics are a necessity in daily life. With the increase of economic income, red wine has become a daily consumer product, so there is an embarrassing situation where red wine drips on non-woven fabrics. Therefore, how to remove red wine from non-woven fabrics efficiently and simply Wine stains have practical value. [0003] The tannins and pigments rich in red wine are easy to oxidize with air, which endows red wine with the characteristics of being easy to oxidize. Therefore, the self-cleaning nonwoven fabric for red wine based on pyridine ionic liquids has good visible light catalytic activity. At present, the methods of producing non-woven fabrics in the market include thermoplastic fiber bonding method. The thermoplastic fiber bonding method is to use therm...
