Problems solved by technology

However, the current passbook magnetic stripe generally has the following disadvantages: 1. Poor wear resistance, the passbook has undergone dozens of times of magnetic head reading and writing wear and tear, resulting in frequent folding; 2. The fracture elongation of the magnetic stripe is large, and the passbook edge remains There are redundant magnetic stripes and debris polluting the surface of the passbook; 3. The peeling strength is high, it is not easy to peel off and break during the magnetic mounting process, and the magnetic stripe cannot be broken neatly at the edge during the magnetic mounting process, which cannot meet the magnetic mounting processing of a single passbook
The above defects lead to unstable passbook quality, high reject rate and poor passbook durability after the magnetic strip is mounted.

Abstract

A transfer magnetic stripe for passbooks comprises a base, a stripping layer, a magnetic layer and an adhesive layer. The stripping layer comprises, by weight, 10.0-70.0 parts of low-elongation macromolecule resins, 5.0-15.0 parts of pigment, 5.0-20.0 parts of aids, 8.0-30.0 parts of 101-B cross-linking agent and 800-1500 parts of solvent. The magnetic layer comprises, by weight, 60.0-80.0 parts of magnetic powder, 10.0-30.0 parts of low-elongation macromolecule resins, 1.0-5.0 parts of dispersing agent, 0.3-1.0 part of aids, 1.5-5.0 parts of 101-B cross-linking agent and 200-400 parts of solvent. The low-elongation macromolecule resins are macromolecule resins with elongation below 300%. The magnetic stripe is easy in stripping, low in elongation at break and breaking tenacity, and neat in edge breaking and free of chips when being adhered to passbooks and passbook covers, and quality of the passbooks is high.

Description

technical field [0001] The invention relates to a magnetic strip, in particular to a special transfer type magnetic strip for passbooks. technical background [0002] A passbook is a running book that records the transactions of customers in the bank, and is the main voucher for customers to reconcile accounts with the bank. The magnetic stripe for passbooks is the carrier for recording customer information in passbooks. It has strong reliability, high data density, low misreading rate, and fast information input and readout. The information reading and writing of magnetic stripes is relatively simple and easy. Easy to use and low cost, it is mainly used in financial service industries such as bank current passbook, regular passbook, medical passbook, rural credit cooperative passbook, etc. It has been widely used due to its good foundation for technology popularization. [0003] The current passbook magnetic strip generally adopts 3 to 4 coatings, that is, a peeling layer,...
