Abstract

The invention discloses a composite material containing silicon dioxide particles. The composite material comprises modified silicon dioxide, titanium dioxide and polylactic acid, wherein the mass ratio of the modified silicon dioxide to the titanium dioxide to the polylactic acid is (0.05 to 0.1) to (0.01 to 0.03) to (50 to 60); titanium dioxide is added into the material system, so that the material has anti-radiation function, and added sodium alginate enhances the antistatic property of the material.

Description

technical field [0001] The invention relates to a composite material used in textiles, in particular to a composite material containing silicon dioxide particles. Background technique [0002] Nano-silica is ultra-fine and nano-sized, with a size range of 1-100nm, so it has many unique properties, such as optical properties against ultraviolet rays, and can improve the anti-aging, strength and chemical resistance of other materials. Very versatile. Nanoscale silicon dioxide is an amorphous white powder, non-toxic, tasteless, and non-polluting. Its microstructure is spherical, and it is a quasi-granular structure of floc and net. Silica nanoparticles play an important role in functional textiles, such as anti-ultraviolet, far infrared, antibacterial and deodorizing, anti-aging, etc., and silica nanoparticles can be compounded with other powders to obtain more beneficial function. However, due to its hydrophilicity, silica nanoparticles are difficult to wet and disperse in ...
