Embodiment 1

[0020] Pulverize the Jilin Antu illite ore and add water to make a suspension with a mass fraction of 20%. After fully stirring, let it stand for 48 hours. 1h, let stand for 1h. Take 100mL of the supernatant liquid and place it in a ball mill jar, then weigh 200g of zirconia large balls (Φ3) and 100g of zirconia small balls (Φ2.2) into the jar, stir well to make them evenly mixed. Afterwards, ball milling was carried out at a speed of 1200 r / min, and a high-purity ultrafine illite solution was obtained after ball milling for 1 hour. The UV-Vis ultraviolet transmittance test was carried out on the above sample, and the results showed that it could shield 52% of UVA, 59% of UVB and 68% of UVC. Then add water to the above-mentioned high-purity ultrafine illite solution to prepare a suspension with a solid content of 20 g / L, add 0.1 g of HPMC at the same time, and magnetically stir for 12 hours to obtain an anti-ultraviolet finishing solution. Put the fabric in the finishing pro...

Embodiment 2

[0022] Grind Jilin Antu illite raw ore and add water to make a suspension with a mass fraction of 10%. After stirring fully, let it stand for 48 hours. 1h, let stand for 1h. Take 100mL of the supernatant liquid and place it in a ball mill jar, then weigh 250g of zirconia large balls (Φ3) and 100g of zirconia small balls (Φ2.2) into the jar, stir well to make them evenly mixed. Afterwards, ball milling was carried out at a speed of 1200 r / min, and a high-purity ultrafine illite solution was obtained after ball milling for 2 hours. The UV-Vis ultraviolet transmittance test was carried out on the above sample, and the results showed that it could shield 44% of UVA, 51% of UVB and nearly 60% of UVC. Then add water to the above-mentioned high-purity ultrafine illite solution to prepare a suspension with a solid content of 10 g / L, add an appropriate amount of polyethylene glycol at the same time, and magnetically stir for 12 hours to prepare an anti-ultraviolet finishing solution. ...

Embodiment 3

[0024] Pulverize the Jilin Antu illite raw ore and add water to make a suspension with a mass fraction of 20%. After fully stirring, let it stand for 48 hours. 1h, let stand for 1h. Take 100mL of the supernatant liquid and place it in a ball mill jar, then weigh 200g of zirconia large balls (Φ3) and 150g of zirconia small balls (Φ2.2) into the jar, stir well to make them evenly mixed. Afterwards, ball milling was carried out at a speed of 1200 r / min, and a high-purity ultrafine illite solution was obtained after ball milling for 1 hour. The UV-Vis ultraviolet transmittance test was carried out on the above sample, and the results showed that it could shield 45% of UVA, 53% of UVB and 62% of UVC. Then add water to the above-mentioned high-purity ultrafine illite solution to prepare a suspension with a solid content of 20 g / L, and add an appropriate amount of HPMC at the same time, and magnetically stir for 12 hours to prepare an anti-ultraviolet finishing solution. Put the fa...

Abstract

The invention relates to an illite mineral based waterborne anti-ultraviolet finishing liquid preparation method and application of waterborne anti-ultraviolet finishing liquid to high polymer material ultraviolet shielding and protection. High-purity illite is subjected to superfine treatment according to a wet milling method by making full use of lamellar structural characteristics and light reflection effects of illite, and consequently lamellar illite can be completely stripped into micro-lamellar illite thinner and smaller in particle size to enhance ultraviolet reflection and refractioneffects to shield ultraviolet to greater extent. Due to a high-purity superfine state of the lamellar illite, prepared illite-based finishing liquid is great in coating performance, aqueous, nontoxicand free of influences on textile hand feel. The method is simple in production process, low in cost, high in yield and efficiency and suitable for industrial production. The obtained superfine illitefinishing liquid has a great ultraviolet shielding performance and can be applied to anti-ultraviolet finishing of textiles and ultraviolet protection of outdoor products, and a novel idea is provided for high-added-value development and utilization of illite.

Description

technical field [0001] The invention belongs to the field of development and utilization of mineral materials, and in particular relates to a preparation method of an illite mineral-based water-based anti-ultraviolet finishing solution and its application in ultraviolet shielding and protection of polymer materials. Background technique [0002] Illite is a common 2-octahedral sheet-like clay mineral, named after it was first discovered on Erie Island in the United States. Its crystal structure is similar to that of 2:1 type mica, which is a sandwich-like TOT unit layer structure formed by sandwiching an octahedral layer between two tetrahedral layers facing each other. Illite is a non-expanding clay mineral that contains more interlayer water than mica. Pure illite usually has fine grains, light white and soft, silky and shiny surface, and is different from other common clay minerals in physical properties. my country has abundant illite resources, but compared with tradi...
