Изобретение относитс к радиотехнической промышленности, в частности, к способу нолучени носител магнитной записи на полпэтилентерефталатной основе.FIELD OF THE INVENTION The invention relates to the radio industry, in particular, to a method for obtaining magnetic recording media on a polyethylene terephthalate basis.
Известны способы изготовлеип носител магнитной заннси нутем нанесени рабочего сло па основу из нолиэтилептерефталата.Methods are known for the manufacture of a magnetic carrier medium by applying a working layer to a substrate of nylethylethyl terephthalate.
Одпако при прпмеиении известных способов сложпо обеспечить хорошую адгезию рабочего сло к основе пз нолиэтплентерефталата.However, when applying the known methods, it is necessary to ensure good adhesion of the working layer to the basis of pz nolyet telenterephthalate.
С пелью увеличеип адгезпп рабочего сло к основе из полпэтилентерефталата но предлагаемому способу перед нанесением рабочего сло основу из полиэтплентерефталата покрывают раствором сополиэфира .из терефталиевой кислоты, этиленглнкол и дпэтиленглпкол в хлоросодержащпх углеводородах .Before applying the working layer, a polyethylene terephthalate base is coated with a copolyester solution of terephthalic acid, ethylene glycol and dipethylene glycol in chlorine-containing hydrocarbons.
В качестве промежуточного сло используетс сополиэфир терефталевой кислоты этиленглйкол и диэтплепглнкол с соотношением носледних от 55 :45 мол. % до 65:35 мол. %.A terephthalic acid copolyester, ethylene glycol and diettleplegne, is used as an intermediate layer with a nasolace ratio of 55: 45 mol. % to 65:35 mol. %
В смеси растворителей, состо ш,ей из метиленхлорида и дихлорэтана в соотношении 3 : 1 раствор етс сополиэфир на основе терефталиевой кислоты, этиленглйкол и диэтиленгликол с соотношением последних 62 :38 мол. %.In a mixture of solvents consisting of 3: 1 methylene chloride and dichloroethane, a copolyester based on terephthalic acid, ethylene glycol and diethylene glycol with the ratio of the last 62: 38 mol. %
в течение 4 час, полученный (0,1-2,5%) раствор наноситс па полнэтнлентерефталатную основу, сушнтс при температуре 40Ч;5°С, после чего наноснтс ферромагнитное нокрытие .for 4 hours, the obtained (0.1-2.5%) solution is applied on a full-ethnol terephthalate base, dried at a temperature of 40 ° C; 5 ° C, after which a ferromagnetic coating is applied.
Таким образом, полученна магнитна лента исиытываетс на держанне нокрыти нараллельно с образцом без подсло . У неподслопрованной магнитной лентыThus, the resulting magnetic tape is searched on the holder with the sample parallel to the sample without a sublayer. Unslapped tape
после п тидес тпкратного изгиба наблюдаетс отделенне магнитного покрытн , а у нодслоированной магнитной ленты магнитный слой не отдел етс после двухсоткратного нзгиба .after five times of bending, a separate magnetic coating is observed, and in a non-laminated magnetic tape, the magnetic layer does not separate after two hundred times.
Таким образом, при сравнении испытаний иодслой пз сополиэфира на основе терефталиевой кислоты этиленглйкол обеспечиваетс хороша адгези ферромагнитного лака к нолиэтилентерефталатной основе.Thus, when comparing terephthalic acid-based ethylene glycol copolyester iodine tests, a good adhesion of ferromagnetic varnish to polyethylene terephthalate is ensured.
