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.

Abstract

The invention discloses a resin composite material and a preparation method thereof. The method comprises the following steps that amination pretreatment and nanocarbon modification are conducted on polyacrylonitrile macroporous adsorption resin; the polyacrylonitrile macroporous adsorption resin is added into an antibacterial composite material dispersing solution, ultrasonic stirring and standing are conducted in sequence, drying is conducted at the temperature of 60 DEG C to 80 DEG C, and then the resin composite material can be obtained, wherein the weight of an antibacterial composite material accounts for 0.5%-1% of the total weight of the polyacrylonitrile macroporous adsorption resin. According to the resin material, the excellent antibacterial property is achieved, graphene quantum dots irradiated by a laser are adopted as carriers of silver, then the carriers are coated with silicon dioxide thin layers and titanium dioxide, surface treatment is conducted, silver is attached to porous graphene finally, therefore, silver nanoparticles and nano-titanium dioxide can be better loaded and fixed to the carbon-modified resin, agglomeration of the silver nanoparticles and nano-titanium dioxide is prevented, the stability of the silver nanoparticles and the like is significantly improved, and the more long-acting antibacterial activity is achieved; meanwhile, the antibacterial properties of the silver particles and titanium dioxide are combined, and compared with a single nano-silver antibacterial agent, the better and lasting antibacterial effects are achieved.

Description

technical field [0001] The invention relates to the technical field of resin materials, in particular to a 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. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a resin composite material and a preparation method thereo...
