Abstract

The invention relates to a method for preparing an upholstery multifunctional air purification function fabric for public transport means, which comprises the following steps: (1) mixing nano Fe3O4, sodium dodecyl benzene sulfonate, methyltrimethoxysilane and ammonium polyphosphate, carrying out ultrasonic dispersion, stirring, controlling a reaction temperature in the range of 30 to 80 DEG C, stirring, adding a catalyst, continuously stirring for 0.5 to 1h, immerging a fabric, dyeing, then carrying out natural drying and baking; and (2) adding bismuth salt, a stabilizer and cetyl trimethyl ammonium bromide into phosphate buffer with stirring, then adding the fabric, dropwise adding phosphate buffer of metavanadate, regulating a pH value of the solution by alkali liquor, and performing reaction for 4 to 8h at a temperature of 70 to 100 DEG C so as to obtain the air purification function fabric. The preparation method is simple to operate, is low in cost, does not increase new equipment and is easy for industrial production; and the composite air purification function fabric prepared by the method has a good air purifying effect, has no secondary pollution and can be used for a long time.

Description

Technical field [0001] The invention belongs to the field of preparation of functional fabrics, and in particular relates to a method for a multifunctional air purification functional fabric for the interior of public transportation vehicles. Background technique [0002] According to the World Health Organization, 1.6 million people die every year due to indoor air pollution, with an average of 1 death every 20 seconds. The annual number of excess deaths caused by indoor air pollution in China has reached 111,000, the number of excess emergency visits has reached 4.3 million, and the direct and indirect economic losses have reached 10.7 billion US dollars. [0003] Nowadays, people basically know the hazards of indoor air pollution in buildings, but consumers know very little about air pollution in cars. In fact, due to the relatively small space in the car and the improper use of interior materials, the content of air harmful substances in the car is much higher than that of ind...
