Description
В качестве материалов дл временной защиты металлических изделий от коррозии вместо смазок в последние годы примен ют снимающиес пленки на основе сплавов эфиров целлюлозы с минеральными маслами, перхлорвиниловые пленки и другие материалы .As materials for temporary protection of metal products from corrosion, instead of lubricants, in recent years, removable films based on alloys of cellulose ethers with mineral oils, perchlorovinyl films and other materials are used.
Первый состав не технологичен, так как его нанос т только методом окунани при 180°С, а перхлорвиниловые пленки требуют применени токсичных и пожароопасных растворителей .The first composition is not technological, since it is applied only by the method of dipping at 180 ° C, and perchlorovinyl films require the use of toxic and flammable solvents.
В Качестве материала дл снимающихс пленок используют также ингибированный латекс на основе сополимера метилакрилата с бутилакрилатом и акрилонитрилом. Однако использование акрилонитрила из-за его высокой токсичности технологически затруднено.Inhibiting latex based on a copolymer of methyl acrylate with butyl acrylate and acrylonitrile is also used as a material for stripping films. However, the use of acrylonitrile due to its high toxicity is technologically difficult.
По предлагаемому способу дл расширени ассортимента материалов, дл временной защиты от коррозии и дл защиты изделий из черных и пветных металлов в услови х повышенной влажности в качестве полимерных пленок примен ют пленки, изготовленные из латекса на основе сополимеров акриловых зфиров с (или без) виниловыми мономерами типа стирола и винилтолуола.In the proposed method for expanding the range of materials, for temporary protection against corrosion and for protecting products from ferrous and pale metals in conditions of high humidity, films made of latex based on acrylic copolymer copolymers with or without vinyl monomers are used as polymer films. such as styrene and vinyltoluene.
Акриловые латексы получают в услови х эмульсионной полимеризации при 74-76°С в присутствии эмульгаторов и инициатора.Acrylic latexes are prepared under the conditions of emulsion polymerization at 74-76 ° C in the presence of emulsifiers and an initiator.
В таблице приведены примерные рецептуры латексов, вес. ч.The table shows the approximate formulations of latex, weight. h
Содержание сухого остатка в латексе 39- 44%, рН 7-9. В латекс ввод т 10-20% (по отношению к сухому остатку) ингибитора коррозии хромовокислого гуанидина, SVo ОП-7 или ОП-10, 2-3% аэросила и воду до необходимой в зкости.The content of dry residue in latex is 39- 44%, pH 7-9. 10–20% (with respect to the dry residue) of a hydrochloric acid guanidine corrosion inhibitor, SVo OP-7 or OP-10, 2-3% aerosil and water to the required viscosity are added to the latex.
Предмет изобретени Subject invention
Снособ временной защиты металлов от коррозии снимающимис полимернымн пленками , содержащими хромовокислый гуаниднн и полиэтилепоксидные соединени , отличающийс тем, что, с целью расширени ассортимента материалов, дл временной защиты от коррозии, в качестве полимерных пленок примен ют пленки, изготовленные из латекса, на основе сополимеров акриловых эфиров с (или без) виниловыми мономерами типа стирола и винилтолуола.Method for temporary protection of metals from corrosion by removing polymer films containing chromic acid guanidine and polyethylene oxide compounds, characterized in that, in order to expand the range of materials for temporary protection against corrosion, films made of latex based on acrylic copolymers are used as polymer films esters with (or without) vinyl monomers such as styrene and vinyltoluene.
