[0022] The preparation method of above-mentioned silver paste ink of the present invention, as figure 1 , follow the steps below to implement:

[0023] Step 1. Weigh each component, the total mass percentage is 100%, of which the aluminum powder is 48.72%-51.22%, the particle size is 11-14μm, the solvent is 24.65%-27.75%, and the surface modifier is 0.49%- 1.02%, dibutyl phthalate is 0.5%-0.6%, acrylic resin is 19.51%-25.64%;

[0024] Step 2. Compare the quality of aluminum powder weighed in step 1, and weigh ethyl acetate according to the ratio of aluminum powder to ethyl acetate mass ratio of 3:5, add the ethyl acetate weighed in this step to step 1 and weigh In the aluminum powder, stir with a magnetic stirrer for 2-3h, filter after standing for 2-3h, and dry at 40-60°C for 2-3h to obtain pretreated aluminum powder;

[0025] Step 3. Put the solvent weighed in step 1 into a beaker, add the surface modifier weighed in step 1, stir with a magnetic stirrer for 20-30 minutes, ...

Embodiment 1

[0029] According to the above-mentioned silver paste ink preparation method, as figure 1 As shown, follow the steps below to implement:

[0030] Step 1. Weigh each component, the total mass percentage is 100%, wherein the aluminum powder particle size is 12 μm, the aluminum powder is 51.22%, the solvent is 27.75%, the surface modifier is 1.02%, dibutyl phthalate 0.5% for acrylic resin and 19.51% for acrylic resin. The surface modifier is composed of 15% oleic acid, 30% sodium dodecylbenzene sulfonate, and 55% sodium stearate; the solvent is 45% ethyl acetate, 25% ethylene glycol Alcohol butyl ether, 30% ethylene glycol composition;

Abstract

The invention discloses a silver paste printing ink for scratch notes, which comprises the following components in mass percentage: 48.72 to 51.22 percent of aluminum power, 24.65 to 27.75 percent of solvent, 0.49 to 1.02 percent of surface modifier, 0.5 to 0.6 percent of dibutyl phthalate and 19.51 to 25.64 percent of acrylic resin based on the total mass of 100 percent. The invention also discloses a method for preparing the silver paste printing ink, which comprises the following steps of: 1) weighing each component; 2) weighing ethyl acetate according to a mass ratio of 3: 5 based on the weighed mass of the silver power, adding the ethyl acetate into the silver powder, magnetically stirring the mixture, standing the mixture, filtering the obtained product and drying the filtrated product to obtain the preprocessed silver powder; 3) adding the weighed solvent into the surface modifier, magnetically stirring the mixed material and standing the mixed material to obtain the mixed modifier; and 4) adding the preprocessed silver powder into the mixed modifier, magnetically stirring the mixture and standing the mixture; adding dibutyl phthalate into the obtained product and magnetically stirring the mixed substance; and adding the acrylic resin into the mixed solution and mixing the mixed product to obtain the silver paste printing ink. The glossiness of the silver paste printingink of the invention is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of printing and packaging materials, and relates to a silver paste ink used for scratch-off bills, and also relates to a preparation method of the silver paste ink. Background technique [0002] Silver paste ink is a kind of aluminum powder ink. Aluminum powder ink is the most widely used and most diverse type of metal ink. It has a good metal effect and has a huge market demand. Aluminum powder has a good ability to reflect light, forms a good metal film in the ink, can reflect visible light, ultraviolet rays and infrared rays, and is silvery white when it reflects visible light, making it have good decorative and covering properties; the reflection of ultraviolet rays can be Protect the coating from ultraviolet damage and prolong the life of the coating; the reflection of infrared rays makes it have the thermal insulation performance of reflecting heat radiation. After nearly a century of continuous devel...
