Problems solved by technology

However, in the existing methods, metal ions such as nano-silver and matrix resin cannot be tightly combined (especially when the content of nano-silver particles increases, agglomeration is prone to occur), and it is easy to fall off during use, thereby affecting the service life and antibacterial effect.
At the same time, the existing resin materials have a single function, and one resin material cannot meet various needs. Often, resin materials with multiple functions are mixed, but it is difficult to achieve the desired effect.

Abstract

The invention discloses a formaldehyde-removing resin composite material and a preparation method thereof. The method includes the steps of firstly, performing amination preprocessing on polyacrylonitrile macroporous resin; secondly, adding the polyacrylonitrile macroporous resin of the first step into a diatomite / porous carbon dispersing solution, performing ultrasonic stirring, standing for 60 minutes, and drying under 60-80 DEG C to obtain the formaldehyde-removing resin composite material, wherein antibacterial composite materials account for 0.5-1% of the total weight of the polyacrylonitrile macroporous resin, and diatomite / porous carbon accounts for 0.5-1% of the total weight of the polyacrylonitrile macroporous resin. The formaldehyde-removing resin composite material and the preparation method thereof have the advantages that diatomite and the antibacterial composite materials are reasonably coordinated to allow the resin material to have excellent antibacterial and formaldehyde-removing performance, the requirements of the multifunctional resin material are satisfied, and the application of the resin material is further expanded.

Description

technical field [0001] The invention relates to the technical field of resin materials, in particular to a formaldehyde-removing resin composite material and a preparation method thereof. Background technique [0002] At present, antibacterial materials prepared by various metal ions have become a research hotspot, such as the preparation of new broad-spectrum antibacterial functional fibers by chemical modification of organic polypropylene nitrile fibers, and metal complexed broad-spectrum antibacterial functional fibers. However, in the existing methods, metal ions such as nano-silver cannot be tightly combined with the matrix resin (especially when the content of nano-silver particles increases, agglomeration is prone to occur), and it is easy to fall off during use, thereby affecting the service life and antibacterial effect. At the same time, the existing resin materials have a single function, and one resin material cannot meet various needs. Often, resin materials wit...
