Process for producing microprism reflective crystal lattice strip and microprism reflective crystal lattice strip

Abstract

The invention discloses a process for producing a microprism reflective crystal lattice strip. Compared with a pyramid subjected to hot press molding in the prior art, a resin pyramid subjected to ultraviolet (UV) light source radiation curing has higher hardness and is firmly bound to a film. In addition to a reflective effect, a metal reflection layer forms a protective layer with a tear-resistant base material, so that the tensile tearing strength of the produced microprism reflective crystal lattice strip is greatly improved, the folding resistance and wear resistance are improved, and the microprism reflective crystal lattice strip is difficultly broken and damaged and can be repeatedly washed at a moderate temperature. When the microprism reflective crystal lattice strip produced by the production process is influenced by external factors such as washing, extruding, scraping and temperature change, a good reflective effect is always kept, and a safety protection effect is achieved. The invention also discloses a microprism reflective crystal lattice strip.

Description

technical field [0001] The invention relates to the technical field of reflective film production, in particular to a production process for a microprism reflective lattice strip and the microprism reflective lattice strip. Background technique [0002] Reflective lattice tape with micro-prism structure is more and more widely used in various road traffic safety facilities, vehicle passive safety protection devices, signs and personal safety protection products due to its excellent retroreflective performance and excellent aging resistance and other fields. The so-called microprism structure refers to a pyramid composed of three two-by-two perpendicular planes, which can perform total internal reflection on the incident light from the front surface, thereby greatly improving the reflection efficiency of the incident light. [0003] In the prior art, the production method of the microprism reflective lattice tape is mainly the spaced hot pressing method, that is, the film an...

AI Technical Summary

Problems solved by technology

However, when the pyramid formed by hot pressing is affected by external factors such as extrusion, weather changes, and washing, it is easy to be damaged and deformed, resulting in a significant decline in the reflective function, unable to maintain the consistency of the reflective brightness of the material, and easily causing safety hazards. Moreover, the existing microprism reflective film usually uses release paper or polyvinyl chloride film as the substrate. This product has poor tear strength, poor folding resistance and wear resistance, and cannot be washed with medium temperature water. It is easy to be damaged during production or use, which affects the service life
