Embodiment 1

[0021] A formaldehyde repellent for textile fabrics, comprising the following components in parts by weight: 12 parts of nano-modified rectorite, 4 parts of 1-vinylimidazole, 2 parts of methylguanamine, 0.6 part of guanidinourea phosphate, and 1.6 parts of antibacterial agent , 2 parts of aromatic agent, 0.3 part of surfactant, 5 parts of polyvinyl alcohol, appropriate amount of distilled water.

[0022] Among them, the nano-modified rectorite is specifically nano-mesoporous alumina / nanometer Maya blue-modified rectorite. The preparation steps are as follows: add rectorite to distilled water 10 times its mass, and place it in a disperser at 75°C at a high speed. Stir for 5 minutes, then add octadecyltrimethylammonium chloride accounting for 3% of the rectorite mass and a mixed solution accounting for 5% of the rectorite mass, continue stirring at a high speed for 30-40min, and freeze-dry to obtain a powder; Blend the powder, nano mesoporous alumina, and nano Maya blue, put it ...

Abstract

The invention discloses a textile fabric formaldehyde remover and preparation and application thereof. The textile fabric formaldehyde remover is composed of, by weight part, 8-14 parts of nano modified rectorite, 2-5 parts of 1-vinyl imidazole, 1-4 parts of acetoguanamine, 0.2-0.7 part of amidinourea phosphate, 1.2-1.8 parts of antibacterial agent, 0.5-2 parts of aromatics, 0.1-0.4 part of surfactant, 3-8 parts of polyvinyl alcohol and distilled water as balance. The textile fabric formaldehyde remover, which is prepared through reasonable formula and processes, is high in specific surface area and self-cleanliness, and compared with traditional absorbent agent of activated carbon, improves the porosity by more than 55% and prolongs the service life by more than 3 times. Meanwhile, the textile fabric formaldehyde remover obtains excellent anti-static, anti-bacteria, antifungal, radiation-proof and fabric-softening effects and achieves a formaldehyde removing rate within 20 minutes up to 99.2%, thereby being efficient and rapid.

Description

technical field [0001] The invention relates to the technical field of formaldehyde repellent, in particular to a formaldehyde repellent for textile fabrics and its preparation and application. Background technique [0002] Formaldehyde is a colorless gas with a pungent odor, easily soluble in water, alcohol and ether. Formaldehyde has a wide range of uses in industry. It is often used in textiles, dyes, leather, resins, paints, plastics, rubber, pharmaceuticals, explosives, etc. Therefore, formaldehyde pollution mainly comes from the above products. The harm of formaldehyde to the human body is mainly manifested in the following aspects: formaldehyde can combine with the protein in the protoplasm of somatic cells, change the internal structure of the protein and solidify, so it has biocidal power. At low concentrations, it initially irritates the mucous membranes of the eyes, and at high concentrations, it irritates the upper respiratory tract, causing coughing, chest ti...
