Abstract

The invention relates to a carpet material with a formaldehyde removal function and a preparation method of the carpet material. The preparation method comprises the following steps: in the whole process of synthesizing manganese dioxide by using potassium permanganate and manganese salt as raw materials, treating a reaction system by an ultrasonic nanocrystallization device, and adding an aqueousacrylic monomer and a carpet base material into the reaction system before reaction starts; meanwhile, after the reaction is carried out for 10-15 min, rapidly cooling to the temperature which is minus 10 DEG C or below at a rate of 9 DEG C / min or above; and taking out the carpet base material, and drying at the temperature of 120-170 DEG C to obtain the carpet material with the formaldehyde removal function. The finally prepared carpet material with the formaldehyde removal function mainly comprises the carpet base material and porous particles which adhere to the carpet base material; the porous particles are made of manganese dioxide, the average particle size is less than or equal to 30 nm, the specific surface area is greater than 300 g / m<2>, the porosity is greater than or equal to40%, and the pore diameter is less than or equal to 5 nm. The preparation method is simple and feasible, and the carpet material prepared by the method is excellent in formaldehyde removal performance.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and relates to a formaldehyde-removing functional carpet material and a preparation method thereof. Background technique [0002] As a toxic gas, formaldehyde deeply affects people's health, and formaldehyde in carpets directly affects the human body. Most of the existing formaldehyde removal technologies are activated carbon adsorption. Activated carbon has a strong adsorption capacity for large molecular weight gases, but its adsorption capacity for small molecular weight formaldehyde is limited, and there is a problem of secondary pollution caused by formaldehyde desorption. [0003] As an efficient catalytic material, manganese dioxide has broad application prospects in the field of formaldehyde purification. The particle size of manganese dioxide particles greatly affects its catalytic activity. The existing manganese dioxide preparation technology is mainly produced through t...
