Description
Известны способы защиты металлов от коррозионного -воздействи агрессивных сред, например кислот, щелочен, нефтепродуктов, путем покрыти металлов лаком. Однако эти покрыти не обладают одновременной стойкостью ко всем указанным агрессивным средам.There are known methods for protecting metals from corrosive effects of corrosive media, such as acids, alkalis, and petroleum products, by coating metals with varnish. However, these coatings do not possess simultaneous resistance to all specified aggressive media.
Предлагаемый способ отличаетс тем, что в качестве лака примен ют раствор фурило-феноло-формальдегидо-поливинилацетальной смолы . Это позвол ет повысить защитные свойства покрыти . По предлагаемому способу в лак .могут быть введены наполнители и пигменты.The proposed method is characterized in that a solution of furyl-phenol-formaldehyde-polyvinyl acetal resin is used as a varnish. This makes it possible to increase the protective properties of the coating. According to the proposed method, fillers and pigments can be introduced into varnish.
При осуществлении способа поверхность металла покрывают лаком Ф-10, полученным из фурило-феноло.-формальдегидо-поливинилацетальной смолы.In the process, the metal surface is coated with F-10 lacquer obtained from furyl-phenol-formaldehyde-polyvinyl acetal resin.
Пример. Поверхность металла зачищают, удал ют жировые п тна , влагу и покрывают лаком Ф-10 (как с наполнителем и пигментом, так и без них) удобным способо.м (маканием, распылением и др.). В кость лака 10-32 сек по вискозиметру ВЗ-4. Покрытие состоит из 3-5 слоев лака. Промежуточные слои покрыти подвергают сущке при 100° в течение 1 часа. После нанесени последнего сло покрытие отверждают при 150-170° Б течение 4-5 час.Example. The metal surface is cleaned, the fatty spots are removed, moisture is coated with F-10 lacquer (both with and without filler and pigment) in a convenient manner (by dipping, spraying, etc.). In the bone of lacquer 10-32 seconds by viscometer VZ-4. The coating consists of 3-5 layers of varnish. The intermediate coating layers are dried at 100 ° for 1 hour. After the last layer has been applied, the coating is cured at 150-170 ° B for 4-5 hours.
