Embodiment 1

[0033] Mix 90mL of absolute ethanol and 10mL of deionized water in a 250mL beaker, adjust the pH value of the solution to 8 with a pH meter, add 10g of rutile nano-titanium dioxide, and pour it into a 250mL flat-bottomed flask after ultrasonic dispersion, and drop in 2g of γ -(Methacryloyloxy)propyltrimethoxysilane (KH570) in ethanol (10mL) solution, stirred and reacted at room temperature for 11 hours. After the reaction, the precipitate was washed three times with ethanol and centrifuged at high speed, and placed in a dry Drying in the oven gave 8.04 g of white product, yield 80.40%.

Embodiment 2

[0035] Mix 95mL absolute ethanol and 10mL deionized water in a 250mL beaker, adjust the pH value of the solution to 8.5 with a pH meter, add 9g of rutile nano-titanium dioxide, and pour it into a 250mL flat-bottomed flask after ultrasonic dispersion, and drop in 3g of γ -(Methacryloyloxy)propyltrimethoxysilane (KH570) in ethanol (5mL) solution, stirred and reacted at room temperature for 12 hours. After the reaction, the precipitate was washed three times with ethanol and centrifuged at high speed, and placed in a dry After drying in the box, 8.04 g of white product was obtained, with a yield of 82.35%.

Abstract

The invention provides a preparation method of an organic and inorganic hybridized anti-ultraviolet finishing agent based on nano titanium dioxide. The preparation method comprises the following steps: mixing absolute ethyl alcohol and de-ionized water; adjusting the pH (Potential of Hydrogen) value of the solution to 8 to 9; adding rutile type nano titanium dioxide; after carrying out ultrasonicdispersion, dropwise adding an ethanol solution of gamma-(methacryloyloxy)propyltrimethoxysilane (KH570); stirring to react at room temperature; after finishing reaction, washing sediment with alcoholfor three times and centrifuging at a high speed; drying to obtain the KH570-TiO2 hybridized anti-ultraviolet finishing agent. According to the preparation method provided by the invention, a monomeris finished on a polyester fabric, and two finishing manners including a traditional rolling and roasting technology (PDC) and an electron beam radiation technology (EB) are adopted to prepare a fabric with excellent anti-ultraviolet performance.

Description

technical field [0001] The invention relates to the technical field of anti-ultraviolet finishing textiles, in particular to a preparation method of an organic-inorganic hybrid anti-ultraviolet finishing agent based on nano-titanium dioxide and its application in polyester fabrics. Background technique [0002] Today's world economy is developing day by day, people's quality of life is gradually improving, and the accompanying environmental pollution is becoming more and more serious. As a major branch of synthetic fibers, polyester plays an important role. Long-term ultraviolet radiation will cause the fabric to turn yellow, so how to improve the anti-ultraviolet ability of the fabric is very important. [0003] In recent years, nanotechnology has developed rapidly, and people are interested in nano-TiO 2 The interest in the research and its application has also increased, especially for the more conventional TiO 2 Rutile nano-TiO with extremely high absorption and shiel...
