Method for preparing ultraviolet shielding textile composite fabric with graphene nanoplatelets

Abstract

The invention provides a method for preparing an ultraviolet shielding textile composite fabric with graphene nanoplatelets. The method is characterized by comprising the following steps: performing shock dispersion on a graphene nanoplatelet solution and a nano titanium dioxide solution and adding into a certain quantity of adhesive solution, and fully stirring the mixed solution, wherein the composite fabric is prepared from the following raw materials in percentage by weight: 30-60 percent of graphene solution, 10-30 percent of nano titanium dioxide solution and 30-60 percent of adhesive solution; performing coating with a transfer coating method; performing high-temperature ultraviolet curing on a graphene coating fabric for 5-30 minutes and drying at 75-95 DEG C; and after the fabric is cooled, stripping the graphene coating fabric from transfer coating paper, thereby obtaining the composite material with the ultraviolet shielding function. The method is simple and reasonable in process, easy to operate and high in yield; the using amount of the graphene nanoplatelets is less, and the composite fabric has the high ultraviolet shielding function and can be used in functional textile products such as ultraviolet shielding sun umbrellas and protective clothing.

Description

technical field [0001] The invention relates to the technical field of textile product manufacturing, and specifically relates to the processing technology of textile fabrics with protective functions, in particular to a preparation method of nano-graphene microchip ultraviolet-shielding textile composite fabrics. Background technique [0002] With the rapid development of global industrialization, the air has been seriously polluted, the atmospheric ozone layer has been destroyed, the thickness of the ozone layer has decreased, and the short-wavelength ultraviolet rays radiated to the earth from the sun have increased. An appropriate amount of ultraviolet rays can make the human body synthesize vitamins and kill some microorganisms and viruses, but excessive intake of ultraviolet rays and short-waves will cause major harm and impact on the human body; long-term exposure to ultraviolet rays will cause people's skin to produce melanin, sunburn and sunburn, if sunburn and sunbu...

Problems solved by technology

The above two types of shading agents are used to prepare anti-ultraviolet fabrics by blending spinning and post-finishing methods. For inorganic reflectors, their large specific surface area can produce diffuse reflection on ultraviolet rays to achieve anti-ultraviolet effects, but their anti-ultraviolet effects are stable. Performance and efficiency need to be impr...
