Problems solved by technology

[0005] CN203025366U discloses a kind of colored reflective product, is provided with base material, colored resin layer, coating film layer, micro-coating layer and glass bead layer successively from bottom to top, and it increases coating film between colored resin layer and glass bead layer layer to improve the reflective performance while ensuring the color effect of the product. However, because the color display is directly added to the resin layer to make the resin layer have the color performance, the color will still be affected by the coating, and the product color distortion
[0007] However, the product made by the above method produces color from the color layer, but there is more distortion than the expected color, and the retroreflection coefficient is low.

Abstract

The invention relates to a positive black high-brightness reflecting material and a preparation method thereof. The positive black high-brightness reflecting material comprises a base material layer, wherein a composite adhesive layer is arranged on the base material layer, a black color modulation layer is arranged on the composite adhesive layer, a mixed layer of a reflection layer and the black color modulation layer is arranged on the black color modulation layer, a color regulation channel layer is arranged on the mixed layer and is used to allow a black color modulation adhesive layer to display black through a regulation channel and a metal plating layer without influence of the brightness, a glass micro-bead layer is arranged on the color and metal mixed layer, and black light absorption compositions fill between the glass beads. The positive black high-brightness reflective cloth displays positive black in sunlight and displays a reflective effect in a retro-reflective state, has a very obvious effect on improving the visibility of a wearer at night or in an environment with poor sight, and greatly improves the use of clothes or textiles in consumer products.

Description

technical field [0001] The invention relates to the technical field of reflective materials, in particular to positive black high-brightness reflective materials and a preparation method thereof. Background technique [0002] The reflective material produces a strong reflective effect under the light source, which has the purposes of marking and warning, and also provides safety guarantee for walking at night. Reflective materials are widely used in life-saving clothing, traffic police clothing and other fields, and with the maturity of the production process of reflective materials, the application field of reflective cloth is also expanding. With the application of reflective materials in consumer clothing, people's requirements for the aesthetics of reflective materials are also getting higher and higher. At present, the color reflective materials on the market either require color and color compounding but the reflection brightness is very low, or the reflection brightn...
