Description

Известен способ ио.чучени  защитных лаков на основе эпоксидны: смол. Однако водосто1 1кость покрыти:, выполненных при помощи этих .лаков, недостаточна вс.ледствие в эпоксидных смолах некоторого количества свободных фенольных гидрокси/юв.There is a known method of protecting epoxy-based protective varnishes: resins. However, the water resistance of coatings: made with these lacquers is not sufficient, as a result, in epoxy resins of a certain amount of free phenolic hydroxy / ju.

С це;1ью получени  водостоиких защитных покрытиГ:. например, дл  медных барабанов 1ил лтовальных мажин, предлагаетс  добавл ть в эпоксидный лак перед его нанесением некоторое количество окислов металлов (СаО, РЬО), способных св зьиипь {|)еиольные гидроксилы с образованием металлических люстикоп.For the first time to obtain a water-resistant protective coating. For example, for copper drums, it is suggested to add a certain amount of metal oxides (CaO, PbO) to the epoxy lacquer before applying it (св) ethylene hydroxyls to form metallic lustikop.

Ко.чичество окислогз eтaллoв рассчитываетс  в соответствии с содержанием в лаке свободных фенольных гидроксилов, например, к лаку э-4100 (30%-иы| раствор смолы э-41 в органических :)астворител х( перед его нанесением добаил ют окись кальцп.  в количестве 0.05% или .окись свинца в количестве 0,2% от веса .чы. Дл  бо.чее ио.чного р.ззмешивани  окись метал.-ia предварительно растирают с небольшим ко . ичество, лака э-4100 и ..иинь затем добав.ч ют в общую массу. В ириготов .ченный таким образом лак ввод т отие11дитель и нанос т его на иодлежащмо зап1ите иоверхиость в 2-3 сло  с промежуточной гор чеГ сущкой в течение двух часов после нанесени  каждого сло .The oxidative content of etacs is calculated according to the content of free phenolic hydroxyls in the lacquer, for example, e-4100 lacquer (30% solution of e-41 resin in organic:) solvents (before it is applied, Calcium oxide is added amount of 0.05% or lead oxide in the amount of 0.2% by weight. of chips. For the boiling water of the mixed mixing, the metal oxide — ia is pre-ground with a small quantity, lacquer e-4100 and .. then added to the total weight. A varnish thus added to the irigots is introduced from the driver and applied to the surface. 2-3 with intermediate layers of mountains cheg suschkoy within two hours after application of each layer.
