(57) Abstract:

Usage: the composition of the oil impregnating materials for impregnation of wood, in particular, for impregnation of wooden sleepers and rails to protect them from fungi and bacteria. The essence of the invention: creating effective fungicidal and preservative properties antiseptic oil impregnation, reducing its temperature curing and preventing sludge formation. Offer antiseptic oil impregnation contains as the basis obespekoeny and obessolennuyu resin, which is a waste product of phenol and acetone, and ethylbenzol resin, which is a waste product of ethyl-benzene as a diluent in the following ratio, wt.%: obespokoennaya resin 62 - 82; etilbenzene resin 18 - 38.

The invention relates to compositions of oil impregnating materials and can be used for impregnation of wood, in particular for impregnation of wooden sleepers and rails to protect them from fungi and bacteria.

Known oil impregnating material [1] is used as a diluent coal sleeper impregnation oil Oil oil softening agent XM-1, issue the wood can not.

Closest to the invention is coal sleeper impregnation oil [2] representing a wide fraction of organic origin the following composition [3] 25 about. absorption fraction and about 75. anthracene fraction of coal origin [3, c. 244, Fig. 9 18] Coal sleeper impregnation oil is an effective antiseptic and has the following indicators of physico-chemical properties according to GOST 2770-74 [2]

However, coal sleeper impregnation oil has a number of disadvantages and contains up to 0.3 wt. substances insoluble in toluene, which negatively affects propityvaet wood. Coal oil is prone to sedimentation, which makes transportation and storage. It has a relatively high (minus 2 minus 5oC) pour point, which makes it difficult plums in winter conditions. Coal oil is vysokotlake create effective fungicidal and preservative properties antiseptic oil impregnating, the decrease in the freezing temperature (-20oC) and prevent the formation of precipitation. Due to its chemical composition offer antiseptic much less toxic.

The invention consists in that the antiseptic oil impregnating containing a wide fraction of organic origin and thinner as large fractions of organic origin (210 - 465oC) contains, according to the invention, obespekoeny resin (phenol content of 0.1 to 0.5%) which is a waste product of phenol and acetone as the diluent ethylbenzol resin, which is a waste product of ethylbenzene, in the following ratio, wt.

Obespokoennaya resin 62 82

We offer oil impregnation material was obtained as follows.

Phenolic resin waste production of phenol and acetone is subjected to special treatment to obespechivaniya and desalination. The result is obespokoennaya and demineralized resin containing only 0.1 to 0.5% phenol and 0.1 to 0.15% of inorganic salts. This resin is the basis for the preparation of the proposed antiseptic oil which soaks.
