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 an antibacterial and anti-radiation resin composite material and a preparation method thereof. The preparation method comprises the following steps: carrying out amination pretreatment and carbon modification on polyacrylonitrile macroporous adsorption resin; then adding in an antibacterial composite material and photochromic compound dispersion mixed solution, ultrasonically stirring, standing and drying for subsequent use; and (4) adding in nano bamboo charcoal dispersion liquid, ultrasonically stirring, standing, and drying at the temperature of 60-80 DEG C to obtain the antibacterial and anti-radiation resin composite material. A photochromic compound, nano bamboo charcoal and an antibacterial composite material are matched reasonably and are synergistic, so that the resin material has excellent antibacterial and photochromic properties, meanwhile has anti-radiation and air purification characteristics, and meets requirements of a multifunctional resin material, and application of the resin material is further broadened.

Description

Technical field [0001] The invention relates to the technical field of resins, in particular to an antibacterial and radiation-proof resin composite material and a preparation method thereof. Background technique [0002] At present, antibacterial materials prepared from various metal ions have become research hotspots, such as the preparation of new broad-spectrum antibacterial functional fibers by chemical modification of organic polyacrylonitrile fiber, and metal complex type broad-spectrum antibacterial functional fibers. However, in the existing methods, metal ions such as nano-silver cannot be closely combined with the matrix resin (especially when the content of nano-silver particles increases, agglomeration is prone to occur), and they are 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 multiple needs. It is often through mixi...
