Ultra-high-temperature chemical-resisting label tape

Abstract

The invention provides an ultra-high-temperature chemical-resisting label tape which has special chemical substances on the coating of a printing surface. The temperature-resisting coating composition of the label tape has very good adherence performance to the substrate, can resist heat and weather, and has good ink-absorbing performance when printed. The ultra-high-temperature chemical-resisting label tape is attached with a heat-resisting acrylic adhesive coating on the upper surface of a release paper layer; and a biaxial tensile polyimide film coating is attached on the upper surface of the heat-resisting acrylic adhesive coating, and a polyurethane and epoxy resin copolymer coating is attached on the upper surface of the biaxial tensile polyimide film coating. The tape has excellent extreme high temperature resistance and chemical resistance and welding resistance, can achieve non-scorching, non-brittle and non-cracking, be applicable to the object processing flow of all the high-temperature projects, can save materials and reduce pollution in the processing of workpieces, and can be widely applied to the electronics manufacturing filed.

Description

technical field [0001] The invention relates to a label tape for identification and identification, in particular to a label tape with ultra-high temperature chemical resistance and good printability. Background technique [0002] At present, in the target processing process of high-temperature engineering in the field of electronic product manufacturing, tapes for various purposes are required for identification and identity marking and measurement management, such as: electroplating of printed circuit boards (main boards), patch welding of electronic components Most of the tapes used in the electronics manufacturing industry are required to be fireproof, solderproof, temperature resistant, chemical resistant, and insulating, and can achieve no scorching, no brittleness, no cracks, and good printing The characteristics of convenience and performance are higher than those of ordinary tapes, especially when used in the soldering process of electronic components. In addition t...

AI Technical Summary

Problems solved by technology

The traditional label tapes used in the field of electronic manufacturing that are currently manufactured and used will fail or be damaged when the working temperature is high, and their high temperature resistance, chemical resistance and solder resistance are extremely poor, and the tapes of the prior art cannot meet these requirements. One requirement, need to be improved
