Description

technical field [0001] The invention relates to the use of melt electrostatic spinning technology and inorganic particle and polymer coupling technology to load inorganic catalytic particles on polymer nanofibers to prepare formaldehyde catalytic purification fibers, so as to have efficient performance of catalytic purification of indoor formaldehyde. Background technique [0002] First of all, most indoor formaldehyde catalysts are in powder state, which is easy to agglomerate, has a small contact area with formaldehyde, and has a low effective utilization rate. Moreover, powder catalysts are not easy to shape and are difficult to apply. Fiber curing technology can effectively solve these two problems. The higher specific surface area effectively increases the contact area between the catalyst and formaldehyde, the purification rate is improved, and the fiber is easy to weave, and can be prepared into products of various shapes. [0003] Secondly, there are two traditional ...

Problems solved by technology

[0003] Secondly, there are two traditional methods for preparing catalytic fibers: one is the impregnation method, the catalyst required by the impregnation method must be a soluble chemical, the preparation process will cause air pollution, and the catalytic fiber prepared by the impregnation method has a low degree of soaping , low reusability

Another method is the solution electrospinning technology. Polymers that are insoluble in organic matter cannot be spun, and insoluble inorganic particles must be soluble polymers loaded with inorganic particles before they can be directly spun with polymers. Complicated, and the mechanical properties of the fibers obtained by solution electrospinning are significantly reduced due to the appearance of holes on the surface of the solvent volatilization
