Embodiment 1

[0059] A preparation method for self-cleaning formaldehyde-removing wall cloth, comprising the following steps:

[0060] (1) Preparation of photo-induced free radical polymer composite finishing solution:

[0061] Every 1 kilogram of photo-induced free radical macromolecule composite finishing liquid is made up of the following components: the degree of etherification is 9g of sulfonated polyetheretherketone of 70%; hydrogen atom donor polymer 7g; crosslinking agent 1.7wt% (crosslinking agent Weight accounts for the percentage of sulfonated polyether ether ketone and hydrogen atom donor polymer total weight); An appropriate amount of acetic acid adjusts the pH value of the finishing solution to 5; the balance is deionized water; the hydrogen atom donor polymer is polyvinyl alcohol, The joint agent is glutaraldehyde;

[0062] Preparation steps: Put sulfonated polyether ether ketone and 400mL deionized water into a 3-liter stirring container, heat to 50°C under stirring, and di...

Abstract

The invention relates to a preparation method of a self-cleaning formaldehyde removing wall cloth. The method includes the steps of: preparing 9-21g of sulfonated polyether ether ketone, 7-16g of a hydrogen atom donor polymer, 1.7-12.4wt% of a crosslinking agent, an appropriate amount of acetic acid regulating the pH value of a finishing liquid to 2-5, and the balance deionized water into a 1kg solution; coating a pure cotton fabric with the polymer composite finishing liquid; conducting predrying in a 100DEG C drying oven for 15min; performing baking for 45s in a 160DEG C baking machine for 45s; coating the back of the pure cotton fabric coated with the composite finishing liquid with a nano-Ag water-based resin dispersion liquid, then conducting predrying in a 100DEG C drying oven for 15min and performing baking in a 160DEG C baking machine for 45s; coating the macromolecular resin surface with a gold salt containing foam finishing liquid, and conducting vacuum drying; using 350nm ultraviolet light to conduct irradiation, and reducing gold ions into gold nanoparticles to prepare the self-cleaning formaldehyde removing wall cloth. The wall cloth provided by the invention can effectively degrade toxic and harmful substances and play a role in self-cleaning of wall cloth.

Description

technical field [0001] The invention relates to a preparation method of a self-cleaning formaldehyde-removing wall covering, belonging to the field of functional textiles. Background technique [0002] Formaldehyde (chemical formula HCHO, molecular weight: 30.03) is a colorless gas with a strong pungent odor. Formaldehyde is a highly toxic substance, and it ranks second on the list of priority control of toxic chemicals in my country. Formaldehyde is defined as carcinogenic and teratogenic shape material by the World Health Organization, is the allergen of generally acknowledging, also is one of potential strong mutagen. The lot of documents record, formaldehyde mainly shows aspects such as allotriosmia, stimulation, allergy, abnormal pulmonary function, dysfunction of liver and immunologic dysfunction to health effects. Formaldehyde concentration reaches 0.06-0.07mg / m in every cubic meter of air 3 When the child is mildly wheezing. When the formaldehyde content in the i...
