Embodiment 1

[0030] Weigh 130kg of deionized water, add 20kg of absolute ethanol, stir evenly, add 5kg of β-cyclodextrin compound, ultrasonically disperse for 10 minutes, heat to 60°C, and stir at 600r / min for 30 minutes to obtain Add 25kg of polyether-modified silicone BYK-333 and 15kg of sodium laurate to the first dispersion, heat to 80°C, and stir at a speed of 600r / min for 30 minutes to obtain a second milky white dispersion.

[0031] Specification 210g / m 2 The light-yellow base material cloth is sprayed with the pre-configured second dispersion liquid on the upper and lower sides of the cloth through the spraying equipment, and dried through the drying tunnel. After winding, the finished cloth of anti-fog glasses cloth is obtained in rolls. Gram weight is 260g / m 2 ,The above finished cloth is cut into 15cm×15cm size by cutting equipment, anti-fog glasses cloth with jagged edges at right angles.

Embodiment 2

[0033] Weigh 130kg of deionized water, add 20kg of absolute ethanol, stir evenly, add 5kg of hydroxypropyl β-cyclodextrin, ultrasonically disperse for 10 minutes, heat to 60°C, and stir at a speed of 600r / min for 30 minutes, To obtain the first dispersion, add 25kg of polyether-modified organic fluorine DuPont-3100 and 15kg of sodium dodecylbenzenesulfonate, heat to 80°C, and stir at 600r / min for 30 minutes to obtain the milky white second dispersion liquid.

[0034] Specification 220g / m 2 The white substrate cloth is sprayed with the pre-configured second dispersion liquid on the upper and lower sides of the cloth through the spraying equipment, dried in the drying tunnel, and rolled to obtain the finished anti-fog glasses cloth cloth in rolls. The gram of the finished cloth is Weight is 260g / m 2 , The above finished cloth is cut into 13cm×17cm anti-fog glasses cloth with jagged edges and right angles through cutting equipment.

Embodiment 3

[0036] Weigh 130kg of deionized water, add 20kg of absolute ethanol, stir evenly, add 5kg of hydroxypropyl β-cyclodextrin, ultrasonically disperse for 10 minutes, heat to 60°C, and stir at a speed of 600r / min for 30 minutes, To obtain the first dispersion, add 25kg of polyether-modified organic fluorine DuPont-3100 and 15kg of sodium dodecylbenzenesulfonate, heat to 80°C, and stir at 600r / min for 30 minutes to obtain the milky white second dispersion liquid.

[0037] Specification 220g / m 2 The white substrate cloth is cut into a 13cm×17cm size by a cutting device, with jagged edges and right-angled ordinary glasses cloth. Take 130kg of cut glasses and arrange them in the dipping tank, pour the pre-configured second dispersion liquid into the dipping tank, soak for 30 to 60 minutes, and dry to obtain the finished anti-fog glasses cloth, weigh and calculate the finished product The weight of the cloth is 270g / m 2 .

Abstract

The invention provides anti-fog glasses cloth based on core-shell structure sustained-release microcapsules and a preparation method of the anti-fog glasses cloth. The anti-fog glasses cloth comprises base material cloth and the sustained-release microcapsules sprayed on the base material cloth; the sustained-release microcapsules comprise cyclodextrin compounds and compound surfactants wrapped in the cyclodextrin compounds, and the compound surfactants comprise a nonionic surfactant and an anionic surfactant. The anti-fog glasses cloth is sprayed with the slow-release microcapsules with the core-shell structure, a large number of anti-fog components are effectively wrapped, and the anti-fog glasses cloth has the advantages of being high in anti-fog component storage capacity, long in shelf life and wide in lens application range; in the process that the anti-fog glasses cloth is used for wiping glasses, and the slow-release microcapsule components are transferred and adsorbed to glasses lenses to form transparent molecular layers; when fog is encountered, the anti-fog components can convert small fog drops into a transparent water film, and the purpose of lasting anti-fog is achieved.

Description

technical field [0001] The invention belongs to the field of daily necessities, and in particular relates to an anti-fog glasses cloth based on core-shell structure slow-release microcapsules and a preparation method thereof. Background technique [0002] People who wear glasses often encounter such troubles. When eating, drinking hot water, and entering a warm room from a cold outdoor in winter, fog will appear on the glasses, which seriously affects people's vision. With the requirements for the prevention and control of the new crown epidemic this year, wearing masks has become a norm in people's daily life. Wearing masks has exacerbated the fog troubles of people wearing glasses and seriously affected travel safety. Existing anti-fog glasses wiping cloth can be divided into two kinds of wet type and dry type. Wet eyeglass wiping cloths contain organic solvents and have a severe odor. There are water stains on the surface of the wiped lens, which affects the permeability...
