preparation example Construction

[0031] The invention discloses a self-cleaning hydrotalcite / fiber fabric composite material with both wear-resistant and self-repairing functions and a preparation method thereof. The preparation method specifically includes the following contents:

[0032] (1) Wash the fabric with detergent, rinse with deionized water and ethanol, and dry it for later use.

[0033] (2) under room temperature conditions, a certain amount of divalent metal salt and trivalent metal salt are respectively added to an appropriate amount of deionized water, the divalent metal salt is aluminum nitrate, and the trivalent metal salt is aluminum nitrate, magnesium chloride, nitric acid Magnesium, cobalt nitrate or nickel nitrate. Under the action of the magnetic rotor, stir evenly, the stirring rate is 100-500 r / min, and the stirring time is 5-20 min. After stirring, a homogeneous solution A is formed; then ammonium fluoride and urea are added in batches, and ammonium fluoride and urea are added separat...

[0039]

[0040] Fabrics are washed with detergent, rinsed in deionized water and ethanol, and dried for later use.

[0041] At room temperature, 0.1 mol / L nickel nitrate and 0.05 mol / L aluminum nitrate were added to an appropriate amount of deionized water, and stirred for 10 min at 200 r / min under the action of a magnetic rotor to form a homogeneous solution A; then 0.4 mol / L ammonium fluoride and 0.3 mol / L urea were added, and the precursor solution B of hydrotalcite was obtained after stirring for 20 min respectively.

[0042] The prepared hydrotalcite precursor solution B was put into a hydrothermal reaction kettle, and the cleaned fabric was added to soak it for 20 minutes, then placed in an oven and reacted at 100° C. for 10 hours. After the hydrothermal reaction, the samples were taken out, rinsed with deionized water, and placed in an oven to dry at 50 °C for 12 h before use.

[0043] The fabric grown with hydrotalcite was immersed in an ethanol solution of 0.08mol...

Abstract

The present invention discloses a self -cleaning water / fiber woven composite material and preparation method with a self -cleaning and self -cultivation function.This method adopts the original growth process, including the following steps: First, different types of fabrics such as cotton fabrics and polyester fabrics are cleaned in the mixed solution of ethanol and water, and after dryingLater, add the reactor; second, soak different types of fabrics into the above solutions. After a certain period of time, perform water and heat reactions, and grow different types of water slippery stones on the surface of the fabric;The alcohol solution of fatty acid is modified to obtain a wear -resistant self -repairing water talc to clean the fabric.Different types of water -skid stones can grow evenly on the surface of the fiber beam to form a porous micronering structure. The fabric has excellent self -cleaning performance. The contact angle is above 155 °, and the rolling angle is less than 5 °.

Description

【Technical field】 [0001] The invention belongs to the technical field of functional composite materials, and in particular relates to a self-cleaning hydrotalcite / fiber fabric composite material with both wear-resistant and self-repairing functions and a preparation method thereof. 【Background technique】 [0002] Fabric is one of the important materials for people to survive. It has the characteristics of loose and porous structure and is widely used in various fields, such as medical treatment, clothing, home decoration, bedding, transportation, military field, public places, etc. The fabric has good moisture absorption and water absorption, so it is easily polluted, which limits its application in some occasions. In recent years, superhydrophobic fabrics have received extensive attention as an important functional material. The fabric itself has a certain surface roughness. With the help of the texture structure of the fabric, the micro-nano-level rough structure of the s...
