Process for producing reflective shell and reflective helmet coating reflective shell

Abstract

The invention belongs to the technical field of safety helmets, and in particular relates to a process for producing a reflective shell and a reflective helmet coated with the reflective shell. The production process comprises the following steps of: (1) preparing a PC (Poly Carbonate) sheet with a certain specification; (2) printing ink on the reverse side of the PC sheet; (3) printing ink on the positive side of the PC sheet; (4) coating a high-temperature-resistant film; and (5) performing plastic molding. The reflective helmet comprises a helmet shell, wherein the helmet shell is integrally molded by a foam material; a decorative shell is thermally sealed on the outer side face of the helmet shell at high temperature; the decorative shell is the prepared reflective shell; the helmet shell and the reflective shell are adhered into a whole through a connecting ink layer; and a reflective ink layer is directly arranged on the outermost side of the reflective shell and has an excellent reflective effect. The reflective ink layer can be protected by the high-temperature-resistant film, so that the reflective ink layer does not have stains and scratches, the yield of the reflective helmet is greatly improved, and batch production is realized.

Description

technical field [0001] The invention belongs to the technical field of safety helmets, in particular to a production process of a reflective shell and a reflective helmet covered with the reflective shell. Background technique [0002] At present, the world is advocating energy-saving and carbon-reducing activities. Therefore, more and more people ride bicycles, and the peripheral equipment related to the safety of riders is becoming more and more diversified. Among them, bicycle safety helmets are the most necessary, and are currently on the market. The styles of helmets sold are very diverse. In order to increase the display effect of the rider at night, the helmets are generally designed with reflective strips, reflective stickers, and luminous warning lights to achieve safety when riding at night. [0003] Among them, the reflective strips or reflective stickers are thick, and will fall off after a period of use, making the overall appearance of the bicycle not good, and...

AI Technical Summary

Problems solved by technology

[0003] Among them, the reflective strips or reflective stickers are thick, and will fall off after a period of use, making the overall appearance of the bicycle not good, and the effect is not obvious, and the luminous warning lights must be additionally installed on the bicycle frame, which requires additional costs Purchase and are easy to steal

[0004] There are also some manufacturers who directly spray reflective paint or reflective ink on safety helmets to achieve a reflective effect, but the helmets obtained in this way are relatively rough and have a general reflective effect; The shell is scratched during the heat sealing process, and the defective rate is extremely high
