Background

In recent years, the reflective material has been widely used in various industries due to its metallic texture and the individualized visual effects of flashing and reflecting. However, most of the existing reflective materials are prepared by mixing metal layers, luminescent pigments, glass beads, butyl acetate, reflective resins, dispersants, curing agents and other components in a certain proportion to obtain reflective coatings, and the reflective coatings are connected to carriers such as clothes, sign boards, adhesive tapes, billboards and the like in a manner of electroplating, printing, brushing, adhering and the like, so that the reflective materials have the effects of absorbing light, reflecting light and warning.

Chinese patent CN104834038B discloses a reflective luminescent film, which comprises the following layered structures arranged in sequence: a reflecting layer formed by bonding a plurality of optical elements by an adhesive; an attaching layer for attaching to the surface of the substrate; the optical element is an optical element which is subjected to electroplating treatment in advance and can reflect multiple colors of light, the attaching layer is coated or printed with luminescent powder and color or the luminescent powder and a first pattern to form a luminescent color layer, or the surface of the reflecting layer is coated or printed with the luminescent powder and the color or the luminescent powder and the first pattern to form a luminescent color layer; or the light reflecting layer is electroplated with an electroplated layer for enabling the optical element to reflect multi-color light, the attaching layer is coated or printed with luminescent powder and color or luminescent powder and a first pattern to form a luminescent color layer, or the surface of the light reflecting layer is coated or printed with luminescent powder and color or luminescent powder and a first pattern to form a luminescent color layer; wherein the optical element is provided as a reflective bead composed of glass, ceramic or synthetic resin, and the electroplated material comprises aluminum, silver, tin, chromium, zinc or a combination thereof.

The Chinese invention patent application CN109778554A provides a preparation method of a traffic police uniform reflective fabric with a bacteriostatic effect. The preparation method comprises the specific steps of (1) soaking a fiber fabric containing 45-55 wt% of antibacterial fibers in an aqueous solution of an antibacterial treating agent for 1-2 d, and then removing moisture from the treated fiber fabric in multiple steps to obtain the antibacterial fabric; (2) uniformly stirring and mixing reflective resin, aluminum silver powder, butyl acetate and a curing agent, and then coating the antibacterial fabric prepared in the step (1); (3) pretreating glass microspheres with the weight 0.5-0.8 times of that of the reflective resin, drying, adding the glass microspheres into a sodium dodecyl sulfate aqueous solution with the mass fraction of 60-75% accounting for 10% of the weight of the reflective resin, stirring the mixture in a water bath at 65-75 ℃ for 6-12 hours, cooling, filtering, washing the mixture with distilled water and absolute ethyl alcohol for three times in sequence, and drying the mixture in vacuum at 60 ℃ to obtain coated glass microspheres; (4) and (3) planting the coated glass beads on the PE/PET composite film, and then compounding the coated glass beads on the coating fabric prepared in the step (2) to obtain the antibacterial reflective fabric.
