Embodiment 1

[0045] A kind of preparation method of porous graphene silver-loaded antibacterial composite material, it comprises the following steps:

[0046] (1) Preparation of graphene quantum dot suspension: weigh 0.5g of C60 powder, measure 50ml of concentrated sulfuric acid with a mass fraction of 98%, mix C60 powder and concentrated sulfuric acid in a beaker, place the beaker in an ice-water bath, and simultaneously Stir at a speed of 500rpm to obtain a mixed solution; weigh 0.5g of potassium permanganate powder, and slowly add it to the above mixed solution; remove the ice-water bath and replace it with a water bath, keep the temperature of the water bath at 30~40°C, and react for 8 hours; quickly add 200ml Pure water, filtered, and then dialyzed for 3 days with a dialysis bag with a molecular weight cut-off of 1000, to obtain a suspension of graphene quantum dots; the suspension of graphene quantum dots was stirred at a speed of 100 rpm, while laser irradiation was performed for 30 ...

Embodiment 2

[0052] A kind of preparation method of porous graphene silver-loaded antibacterial composite material, it comprises the following steps:

[0053] (1) Preparation of graphene quantum dot suspension: Weigh 0.6g of C60 powder, measure 80ml of concentrated sulfuric acid with a mass fraction of 98%, mix C60 powder and concentrated sulfuric acid in a beaker, put the beaker in an ice-water bath, and simultaneously Stir at a speed of 500rpm to obtain a mixed solution; weigh 1g of potassium permanganate powder, and slowly add it to the above mixed solution; remove the ice-water bath and replace it with a water bath, keep the temperature of the water bath at 30~40°C, and react for 6 hours; quickly add 200ml of pure Water, filtered, and then dialyzed for 3 days with a dialysis bag with a molecular weight cut-off of 1000 to obtain a suspension of graphene quantum dots; the suspension of graphene quantum dots was stirred at a speed of 100 rpm, while laser irradiation was performed for 40 mi...

Embodiment 3

[0059] A kind of preparation method of porous graphene silver-loaded antibacterial composite material, it comprises the following steps:

[0060] (1) Preparation of graphene quantum dot suspension: Weigh 0.8g of C60 powder, measure 100ml of concentrated sulfuric acid with a mass fraction of 98%, mix C60 powder and concentrated sulfuric acid in a beaker, put the beaker in an ice-water bath, and simultaneously Stir at a speed of 500rpm to obtain a mixed solution; weigh 3g of potassium permanganate powder, and slowly add it to the above mixed solution; remove the ice-water bath and replace it with a water bath, keep the temperature of the water bath at 30-40°C, and react for 5 hours; quickly add 100ml of pure Water, filtered, and then dialyzed for 3 days with a dialysis bag with a molecular weight cut-off of 1000 to obtain a suspension of graphene quantum dots; the suspension of graphene quantum dots was stirred at a speed of 100 rpm, while laser irradiation was performed for 30 m...

Abstract

The invention discloses photochromic gravure water-based ink and a preparation method thereof. The photochromic gravure water-based ink is prepared from, by weight, 70%-75% of water soluble resin, 10%-15% of deionized water, 5%-10% of water-based organic pigment, 3%-6% of ethyl alcohol, 0.5%-1% of kieselguhr/antibacterial compound, 1%-2% of dispersing agent, 0%-1% of slow drying agent, 0.5%-1% of water-based flatting agent, 0.5%-1% of water-based wax emulsion, 0.5%-1% of kieselguhr/inorganic oxide, 0.5%-1% of organic amine, 0.5%-1% of antifoaming agent and 0.1%-2% of photochromic compound. The ink has excellent antibacterial, anti-formaldehyde and deodorization properties and photochromic properties and meets the need for multiple functions, and the application range of the ink is further widened.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a photochromic gravure water-based ink and a preparation method thereof. Background technique [0002] Ink is an important material for printing packaging materials. It expresses patterns and characters on the substrate through printing. The ink includes main components and auxiliary components. They are evenly mixed and rolled repeatedly to form a viscous colloidal fluid; It is composed of pigments, linking materials and additives; it is used in various printings such as books, periodicals, packaging and decoration, and architectural decoration. With the increase of social demand, the variety and output of ink have also expanded and increased accordingly. Gravure printing water-based ink is a new type of ink with low toxicity, no irritating smell, non-flammable, energy-saving and environmental protection, but ordinary water-based ink does not have antibacterial properties. The hi...
