Embodiment 1

[0031] In a device equipped with stirring, reflux and feeding functions, heat the deionized water to 85°C, and slowly add the aluminum isopropoxide dissolved in isopropanol in portions while stirring at a constant temperature (stirring speed is 100rpm), wherein The ratio of aluminum isopropoxide to isopropanol was 1:2 (molar ratio). After all the addition was completed, the mixture was stirred under reflux for 1.5 hours, and a white precipitate was formed. Then heat up to 95°C, and evaporate under stirring conditions until the isopropanol is completely volatilized, then add peptizer hydrochloric acid according to the molar ratio of aluminum isopropoxide:hydrochloric acid 1:0.1, to redisperse the precipitate, and age for 4 hours , to get transparent (or translucent) alumina sol; add 0.1% (weight) PVA and 0.1% (weight) OP-10 based on the weight of alumina sol in alumina sol, stir evenly to obtain nano antistatic Finishing agent.

Embodiment 2

[0033] In a reactor equipped with stirring, reflux and feeding functions, heat the deionized water to a temperature of 80°C, and then slowly add the aluminum isopropoxide dissolved in isopropanol while stirring at a constant temperature (stirring speed is 200rpm) , wherein the ratio of aluminum isopropoxide to isopropanol is 1:3 (molar ratio), and after all the addition is completed, reflux and stir for 1 hour to form a white precipitate. Then heat up to 90°C, and evaporate under stirring conditions until the isopropanol is completely volatilized, then add peptizer hydrochloric acid according to the molar ratio of aluminum isopropoxide:hydrochloric acid 1:0.3, to redisperse the precipitate, and age for 3 hours , to obtain a transparent alumina sol. Adding 0.5% (weight) of PVA and 1% (weight) TX-10 based on the weight of the aluminum oxide sol to the alumina sol, stirring evenly to prepare the nanometer antistatic finishing agent.

Embodiment 3

[0035] In a reaction kettle equipped with stirring, reflux and feeding functions, heat the deionized water to a temperature of 75°C, and slowly add aluminum isopropoxide that has been dissolved with co-solvent isopropanol in stages (three times) while stirring at a constant temperature ( The total time of adding is 30 minutes), wherein the ratio of aluminum isopropoxide to isopropanol is 1:1 (molar ratio), after all the addition is completed, reflux and stir for 2 hours, forming a white precipitate. Then heat up to 100°C, and evaporate under stirring conditions until the isopropanol is completely volatilized, then add the peptizer hydrochloric acid (dilute hydrochloric acid) according to the molar ratio of aluminum isopropoxide:hydrochloric acid 1:0.2, and stir to redisperse the precipitate. After aging for 5 hours, a transparent (incomplete) alumina sol was obtained. Adding 0.3% (weight) of PVA and 0.5% (weight) TX-10 based on the weight of the alumina sol into the alumina so...

Abstract

The present invention discloses a nano antistatic finishing agent, its preparation method and application. The described finishing agent contains alumina sol, PVA whose content is 0.1-0.5 wt% of alumina sol weight and non-ionic surfactant whose content is 0.1-1 wt% of alumina sol weight. Said invention adopts nano-size inorganic material, so that it can obtain good antistatic effect.

Description

1. Technical field: [0001] The invention relates to an antistatic finishing agent for textiles and a preparation method and application thereof, in particular to a nanometer antistatic finishing agent and a preparation method and application thereof. 2. Background technology: [0002] Synthetic fibers such as polyester are hydrophobic synthetic fibers with poor water absorption. During use, static electricity is generated due to friction, causing dust to adhere, making polyester clothing entangled with limbs and causing discomfort, and even harmful to health. Simultaneously because polyester etc. are flammable fibers, the burning of clothes such as polyester may cause human injury, and the burning of decorative fabrics can cause fires such as buildings, automobiles or airplanes. Therefore, it is necessary to carry out antistatic finishing on clothing and decorative fabrics. [0003] To achieve the antistatic purpose of textiles, the most common way in the prior art is to ar...
