摘要 |
FIELD: chemistry. ^ SUBSTANCE: antipyrene is a mixture of products of oxidation of a lignin-containing substrate. The lignin-containing substrate used is wastes from wood-work and timber processing industry. The antipyrene is obtained through liquid-phase oxidation of a lignin-containing substrate in an alkaline medium in the presence or absence of a catalyst at temperature ranging from room temperature to 90C under the effect of an oxidising agent. The oxidising agent is selected from a group comprising air, oxygen, ozone and hydrogen peroxide. The catalyst used is metal salts, primarily copper (II) or cobalt (II) salts. The antipyrene is used in form of a liquid mixture or dry powder of a mixture of products of oxidation of a lignin-containing substrate. The antipyrene is used to produce low-inflammability materials, for fire-retardant processing of articles made from wood and other combustible materials, as well as for extinguishing combustion sources. The liquid mixture of products of oxidation of a lignin-containing substrate is applied onto the surface of a combustible material and dried until formation of a film of antipyrene on the surface of the said material. Alternatively, the mixture of products of oxidation of the lignin-containing substrate is mixed with a solid combustible material and dried. The dry powder of the mixture of products of oxidation of the lignin-containing substrate is added into molten polymer thermoplastic and fire-resistant articles are then mouled from the obtained composite material. A combustion source is treated by the antipyrene by spraying or sprinkling. ^ EFFECT: antipyrene is an efficient, environmentally safe fire-retardant agent. ^ 24 cl, 7 dwg |
