Embodiment 1

[0023] Mix 100g of rare earth, 70g of cycloethanol, 10g of 8-carboxyquinoline and 50g of cyclohexane, and stir thoroughly for 15 minutes, then add 2g of sodium m-carboxybenzoate to obtain microemulsion M; suction filter microemulsion M, and add 15g of Tetra-n-butyl titanate, centrifuged after fully stirring, centrifuged for 3 times, washed alternately with acetone-ethanol mixture (the content of acetone is 20%, the content of ethanol is 80%) and deionized water, at 120 ℃ After baking for 20 minutes, it was ground into powder to obtain antibacterial powder N; 300g epoxy resin, 150g sodium benzoate, 20g aluminum silicate, 105g calcium carbonate, and 20g titanium white powder were mixed and heated in a water bath, and then the obtained antibacterial powder was added. Bacteria powder N was subjected to ultrasonic dispersion for 10 minutes at an ultrasonic frequency of 20KHz to obtain the antibacterial watercolor pigment A1.

Embodiment 2

[0025] Mix 100g of rare earth, 95g of cycloethanol, 25g of 8-carboxyquinoline and 75g of cyclohexane, stir thoroughly for 25min, then add 10g of sodium m-carboxybenzoate to obtain microemulsion M; suction filter microemulsion M, and add 35g of Tetra-n-butyl titanate, centrifuged after fully stirring, and washed alternately with acetone-ethanol mixture (the content of acetone is 45%, the content of ethanol is 55%) and deionized water after centrifugation for 5 times, at 200 ° C After baking for 30 minutes, grind it into powder to obtain antibacterial powder N; mix 400g epoxy resin, 200g sodium benzoate, 30g aluminum silicate, 120g talcum powder, and 45g carbon black powder, heat in a water bath, and then add the prepared antibacterial powder. Bacteria powder N was subjected to ultrasonic dispersion for 20 minutes at an ultrasonic frequency of 25KHz to obtain the antibacterial watercolor pigment A2.

Embodiment 3

[0027] Mix 100g of rare earth, 80g of cycloethanol, 15g of 8-carboxyquinoline and 60g of cyclohexane, and stir thoroughly for 17 minutes, then add 6g of sodium m-carboxybenzoate to obtain microemulsion M; perform suction filtration on microemulsion M, and add 20g of Tetra-n-butyl titanate, centrifuged after fully stirring, and washed alternately with acetone-ethanol mixture (the content of acetone is 30%, and the content of ethanol is 70%) and deionized water after centrifugation for 4 times, at 160 ° C After drying for 25 minutes, grind it into powder to obtain antibacterial powder N; mix 350g of epoxy resin, 170g of sodium benzoate, 25g of aluminum silicate, 110g of kaolin, and 30g of light-resistant yellow powder, heat it in a water bath, and then add the prepared antibacterial powder. Bacteria powder N was subjected to ultrasonic dispersion for 15 minutes at an ultrasonic frequency of 22KHz to obtain the antibacterial watercolor pigment A3.

Abstract

The invention discloses antibacterial watercolor and a preparation method thereof. The preparation method comprises the following steps: mixing rare-earth, cyclohexanol, 8-carboxylquinoline and cyclohexane, sufficiently stirring for 15-25 minutes, and adding sodium m-carboxy benzoate to obtain a micro-emulsion M; adding tetra-n-butyl titanate into the micro-emulsion M, sufficiently stirring, centrifuging for 3-5 times, alternately washing with an acetone-ethanol mixed liquid and deionized water, drying, and grinding powder to obtain antibacterial powder N; and mixing epoxy resin, sodium benzoate, aluminum silicate, packing and a colorant, heating in water bath, adding the prepared antibacterial powder N, and performing ultrasonic dispersion to obtain the antibacterial watercolor. According to the antibacterial watercolor, the problem that mould easily grows on the surface of the traditional watercolor in a humid environment can be solved.

Description

technical field [0001] The invention relates to the field of chemical pigments, in particular to an antibacterial watercolor pigment and a preparation method thereof. Background technique [0002] Pigments are powdered substances used for coloring. It is insoluble in water, oil, resin, organic solvent and other media, but can be evenly dispersed in these media and can make the media color, and has a certain covering power. The pigments used in art basically require that the finer the particles, the better, the brighter the color, the better, and the longer the color does not change, the better. The watercolor paints of watercolor paints are almost transparent except for white. Only in this way can the needs of watercolor cover dyeing be met. After the traditional paint is applied, it is easy to breed mold on its surface in a humid environment, and the traditional paint does not have antibacterial properties. Therefore, it is an urgent problem to be solved by the present i...
