专利申请范围本发明的特征是使用偏二氯乙烯——丙烯腈共聚物,偏二氯乙乙烯——氯乙烯聚共聚物以及湿固型氨脂弹性题,聚氨酯预聚物等反省性聚氨酯树脂为主要成分的粘合剂。把磁粉在这种粘合剂中混合成磁浆后涂布到带基上制成磁带。发明的详细说明本发明的目的是改善记录题的满耐久性。关于磁记录提,特别是计算机,录象方面用的磁带,都要求具有良好的耐磨性。为此,研究人员曾提出过不少有关改进
Patent Application Scope The present invention is characterized by using a vinylidene chloride-acrylonitrile copolymer, a vinylidene chloride-vinyl chloride copolymer and a moisture-curing urethane elastomer, a retroreflective polyurethane resin such as a polyurethane prepolymer, As the main component of the adhesive. The magnetic powder in this binder mixed into a magnetic slurry coated on the tape base made of tape. DETAILED DESCRIPTION OF THE INVENTION The object of the present invention is to improve the full durability of the recorded questions. With regard to magnetic recordings, especially computers, video tapes, are required to have good wear resistance. To this end, researchers have put forward many improvements
