Embodiment 1

[0018] Mix 100 parts of octadecyltrimethylammonium chloride, 100 parts of fumed silicon dioxide, 200 parts of deionized water, and 100 parts of isopropanol and stir them evenly with an electric mixer to make a treatment solution. The temperature is 100°C, pour the treatment solution into 50,000 parts of glass beads in a high-speed mixer, stir and mix evenly, the stirring speed is 1000rps, and the stirring time is 5min, fully mix until uniform, and then bake in an oven at a temperature of 200°C , the time is 90 minutes, and after cooling, it becomes a kind of reflective glass beads 1 .

Embodiment 2

[0020] Mix 100 parts of dodecyltrimethylammonium chloride, 50 parts of fumed silica, 100 parts of deionized water, and 50 parts of isopropanol and stir them evenly with an electric mixer to make a treatment solution. The temperature is 60°C, pour the treatment solution into 30,000 parts of glass beads in a high-speed mixer, stir and mix evenly, the stirring speed is 800rps, and the stirring time is 3min, fully mixed until uniform, and then baked in an oven at a temperature of 150°C , the time is 50 minutes, and after cooling, it becomes a kind of reflective glass beads 2 .

Embodiment 3

[0022] Mix 100 parts of N, N, N-trimethyl-1-tetradecyl ammonium bromide, 1 part of fumed silica, and 1 part of deionized water, mix them with an electric mixer to make a treatment solution, and treat in a water bath The temperature of the treatment liquid is 25°C. Pour the treatment liquid into 10,000 parts of glass beads in a high-speed mixer, stir and mix evenly, the stirring speed is 600rps, and the stirring time is 1min. Fully mix until uniform, and then bake in an oven. The temperature is 50° C., and the time is 10 minutes. After cooling, a kind of reflective glass beads 3 are obtained.

Abstract

The invention relates to the technical field of surface treatment, aims to solve the problem that static electricity is easily produced due to rolling of beads and friction of high-polymer original film in the bead embedding process and provides a surface treatment method of glass micro-beads for light reflection. A cationic surfactant serves as an antistatic agent, nano silicon powder is added to improve free fluidity of powder, meanwhile a dispersion agent makes the surfactant and the nano silicon powder mixed well, then surface treatment is performed, the treated glass beads have good antistatic property and fluidity, and the surface treatment method is suitable for gloss-silver light-reflecting cloth and light-reflecting films.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to a surface treatment method and application of reflective glass beads. Background technique [0002] Reflective cloth is to make high refractive index glass beads on the surface of the cloth base by coating or filming process, so that ordinary cloth can reflect light under the irradiation of light. Reflective cloth can be divided into: general bright reflective cloth, high brightness reflective cloth, bright silver reflective cloth, metal light reflective cloth and so on according to the difference of reflective brightness. [0003] At present, the glass beads used in reflective fabrics are first treated with a coupling agent to achieve a certain fluidity and washing fastness. The friction of the original material film is easy to generate static electricity, and the surface treatment of traditional glass microspheres has not achieved good antistatic and free flow proper...
