Bar code for sulfurizing rubber tyre and its making process

Abstract

The sulfurized rubber tyre bar code is prepared with the materials including butyl bromide, natural rubber, terpene resin, softener, antiager, white carbon black and titanium white powder in certain weight proportion. The preparation process includes the following steps: screen printing bar code and number with the compounded rubber ink on transparent polyester film; coating one layer of white sulfurizing material; and cutting into single bar codes. The bar code is combined with tyre through sulfurizing, and is wear resistant and low in cost. There are bar code and number printed simultaneously for recognition with computer and by human eyes.

Description

technical field

[0001] The invention relates to a barcode and its preparation process, in particular to a rubber tire vulcanized barcode and its preparation process. Background technique

[0002] The application of tire barcodes began in the late 1980s. Michelin was the first to use barcodes on tires. Since the bar code played a very significant role in the production process of tires, quality tracking and production cost control, so in the late 1990s. Major tire manufacturers in the world are also using bar codes one after another. At present, the barcode used is a label barcode, which is a special pressure-sensitive adhesive coated on a white polyester material. The barcode is printed with a barcode printer, and the tire is pasted on the tire before vulcanization. This kind of barcode has the following defects: 1. It is not made of rubber material, and it is easy to fall off; 2. The barcode is large on the surface of the polyester film, which is not resistant to frictio...
