FIELD: process engineering.
SUBSTANCE: invention relates to protective composition for timber. Proposed composition is produced by one-step electrolysis of bischofite solution using zinc electrodes. Said electrolysis is performed at current density of 0.05 A/dm2, voltage of 3 V and electrolyte solution temperature of 20-25°C. Electrolyte density makes 1030 kg/m3 at the following ratio of components, g/l: bischofite - 100-150, oxidiser - 2-2.5, zinc ions - 0.75-1.0.
EFFECT: higher antiseptic and fire resistance properties.
