Description

[0001] Field of technology to which the invention relates

[0002] The invention relates to the field of wood preservation and can be used for impregnating wood, in particular for impregnating wooden sleepers, beams, masts, power lines, elements of wooden structures and building structures.

[0003] The invention is intended to improve the performance properties and extend the service life of wood materials, in particular wooden railway sleepers, sleepers and ship matches, expand the raw material resources of impregnating compounds and improve the sanitary-hygienic and environmental conditions at impregnating plants and in places where impregnated wood materials are used.

[0004] State of the art

[0005] Coal tar sleeper impregnating oil is known [GOST 2770-78. "Coal tar oil for wood impregnation"] (analogue), containing in its composition a narrow oily fraction of thermal origin, which is a mixture of the first anthracene fraction (280-360°C) and absorption oil (235-300°C) [Coke Chemist's Handbook, Vol. 3 / Ed. A.K. Shelkov, - M.: Metallurgy, 1966, p. 66].

[0006] The disadvantages of coal tar sleeper impregnating oil include the following factors.

[0007] 1. Coal tar sleeper impregnating oil contains up to 0.3 wt.% of substances insoluble in toluene (carbenes and carboids) and up to 1.5 wt.% of water, which negatively affects the wood impregnation process.

[0008] 2. In terms of toxicity, coal tar sleeper impregnating oil belongs to the second hazard class (highly toxic), which creates an increased risk in terms of the sanitary, hygienic and environmental conditions of sleeper impregnation plants.

[0009] 3. Coal tar sleeper impregnating oil has a low pour point (from minus 2 to minus 5°C), which makes it difficult to drain and pump in winter conditions.

[0010] 4. A significant disadvantage of coal tar sleeper impregnating oil is its tendency to form sediment, which leads to the need to "wash out the sediment" in railway tank cars and to losses during storage in tanks.

[0011] 5. Coal tar sleeper impregnating oil has an unpleasant and very persistent odor.

[0012] The “Oil antiseptic for wood impregnation” (RU patent No. 2187429, B27K 3 / 50, dated 02 / 20 / 2002) (analogue) is known, containing a wide fraction of heavy gas oil from hard catalytic cracking, boiling in the range of 140-500°C - 90÷99.8 wt.%, and a residue from light thermal cracking, boiling in the range of 380-540°C - 0.2÷40 wt.%.

[0013] The following are some of the disadvantages of the well-known antiseptic liquid:

[0014] 1. This liquid has insufficient fungicidal toxicity towards fungi and bacteria that destroy wooden sleepers and beams.

[0015] 2. The need to use relatively expensive components in its production - catalytic cracking fractions.

[0016] 3. The price of the specified antiseptic liquid is relatively high.

[0017] The closest in technical essence and achieved result to the claimed invention is the “Antiseptic oil impregnating agent for wood preservation (variants) (RU Patent No. 2377121, B27K 3 / 50, B27K 3 / 52, B27K 3 / 22, dated 12 / 27 / 2009) (prototype), containing a fungicide - a product of the interaction of copper or zinc metal salts with saponified naphthenic acids - naphthenates and / or resinates of copper or zinc metal salts, a narrow fraction of light, boiling within 230-360 ° C, and a fraction of light vacuum gas oil, boiling within 360-460 ° C, or a fraction of heavy vacuum gas oil, boiling within 390-520°C, or a darkened vacuum gas oil fraction boiling at 360°C, or a fuel oil fraction boiling at 280°C at the stated component ratio. This method was chosen as the prototype.

[0018] The significant disadvantages of this method include the insufficiently high fungicidal toxicity and resistance of this liquid to woodworms, fungi and bacterial colonies that destroy wooden structures (especially in damp and underground conditions) and insufficient protection from the corrosive activity of the external environment and materials in contact with wood, including metal structures.

[0019] Disclosure of the essence of the invention

[0020] The problem that the claimed invention is aimed at solving is to eliminate the shortcomings of the above-mentioned solutions, in particular the insufficiently high fungicidal toxicity and resistance of this liquid to woodworms, fungi and bacterial colonies that destroy wooden structures (especially in humid and recessed areas).

[0021] The purpose of this invention is to increase the resistance of the treated (impregnated) wooden surface to microbiological damage and to increase (extend) the designated service life of wooden structures and constructions.

[0022] This problem is solved due to the fact that the claimed composition, due to the use of the developed composition, provides high fungicidal toxicity and resistance of the preservative composition in relation to woodworms, fungi and bacterial colonies that destroy wooden structures (especially in humid and recessed areas) and an increase in the corrosion resistance of both the wood itself and concrete or metal products in contact with it due to the addition of a corrosion inhibitor-biocide based on the product of the interaction of fatty amines with various mixtures of higher unsaturated carboxylic acids, their esters.

[0023] The proposed invention solves the technical problem of obtaining a new petroleum-based composition (the base products are products from primary oil refining - fuel oil fractions, secondary vacuum distillation of fuel oil - fractions of light vacuum gas oil, heavy vacuum gas oil, darkened vacuum gas oil, narrow fraction of light), possessing protective (protective) and impregnating (penetrating) properties in relation to wood at a level not inferior to the known impregnating composition, improving the performance properties of impregnating compositions and expanding the raw material resources of oily antiseptics due to the rational use of petroleum refining products. To enhance the biocidal and anticorrosive activity of the composition, it is proposed to additionally use substances based on the products of the interaction of fatty amines with various mixtures of higher unsaturated carboxylic acids, their esters.

[0024] When the listed substances are combined into a composition and the above-mentioned component ratio is maintained, an anti-corrosion and biocidal protective effect is observed in high-humidity environments. This effect indicates the mutually enhancing action of all components. An additional argument in favor of using these substances is the ability to obtain these compounds from readily available raw materials in a single step and with high yield.

[0025] The essence of the invention lies in the fact that the composition for preserving wood, including a fraction of light vacuum gas oil (base), boiling within 360-460 ° C, a narrow fraction of light (UFS), boiling within 230-360 ° C (diluent) (E.F. Kaminsky, V.A. Khavkin, Deep oil refining: technological and environmental aspects, Moscow, 1995, pp. 65-70), a fungicide - a product of the interaction of copper or zinc metal salts with saponified naphthenic acids - naphthenates and / or resinates of copper or zinc metal salts, characterized in that it additionally contains as a corrosion inhibitor-biocide a product of the interaction of fatty amines with various mixtures of higher unsaturated carboxylic acids, their esters in the following ratio components, wt.%:

[0026] light vacuum gas oil fraction 5,0-55,0 narrow fraction of light 30,0-94,0 fungicide 0,5-5,0 inhibitor-biocide 0,5-10,0

[0027] This produces a composition for preserving wood according to option 1.

[0028] The characteristics of the narrow fraction of light and the chemical composition of petroleum products are presented in Tables 1 and 2.

[0029] According to the second variant of the invention, a composition for preserving wood, comprising a fraction of heavy vacuum gas oil - a base, boiling in the range of 390-520°C, a narrow fraction of light - a diluent, boiling in the range of 230-360°C, and a fungicide - a product of the interaction of copper or zinc metal salts with saponified naphthenic acids - naphthenates and / or resinates of copper or zinc metal salts, characterized in that it additionally contains, as a corrosion inhibitor-biocide, a product of the interaction of fatty amines with various mixtures of higher unsaturated carboxylic acids, their esters in the following ratio of components, wt.%:

[0030] heavy vacuum gas oil fraction 5,0-45,0 narrow fraction of light 40,0-94,0 fungicide 0,5-5,0 inhibitor-biocide 0,5-10,0

[0031] According to a third variant of the invention, a composition for preserving wood, comprising a fraction of darkened vacuum gas oil - a base, boiling within 360°C, a narrow fraction of light - a diluent, boiling within 230-360°C, and a fungicide - a product of the interaction of copper or zinc metal salts with saponified naphthenic acids - naphthenates and / or resinates of copper or zinc metal salts, characterized in that it additionally contains, as a corrosion inhibitor-biocide, a product of the interaction of fatty amines with various mixtures of higher unsaturated carboxylic acids, their esters in the following ratio of components, wt.%:

[0032] darkened vacuum gas oil fraction 5,0-35,0 narrow fraction of light 50,0-94,0 fungicide 0,5-5,0 inhibitor-biocide 0,5-10,0

[0033] According to a fourth variant of the invention, a composition for preserving wood, comprising a fraction of fuel oil - a base, boiling within 280°C, a narrow fraction of light - a diluent, boiling within 230-360°C, and a fungicide - a product of the interaction of copper or zinc metal salts with saponified naphthenic acids - naphthenates and / or resinates of copper or zinc metal salts, characterized in that it additionally contains, as a corrosion inhibitor-biocide, a product of the interaction of fatty amines with various mixtures of higher unsaturated carboxylic acids, their esters in the following ratio of components, wt.%:

[0034] fuel oil fraction 5,0-40,0 narrow fraction of light 45,0-94,0 fungicide 0,5-5,0 inhibitor-biocide 0,5-10,0

[0035] A significant distinguishing feature of the proposed technical solution is the inclusion of a corrosion inhibitor-biocide in the impregnation composition, which allows for increasing the microbiological resistance and resistance to atmospheric moisture of both the wood itself and the metal structures in contact with it.

[0036] The presence of an additional biocide inhibitor in the proposed wood preservation composition, which is more resistant to microbiological damage, will increase the microbiological stability of the impregnation composition and, accordingly, extend the designated service life of wooden and metal products and structures.

[0037] The combination of essential features of the proposed technical solution allows for an increase in the microbiological stability of the impregnating composition and, accordingly, the level of protection of the wood composition, as well as the production of a new, more effective and cheaper oil-based antiseptic with high impregnating (penetrating) properties in relation to wood at a level not inferior to the known impregnating composition, improving the performance properties of impregnating compositions and expanding the raw material resources of oily antiseptics due to the rational use of petroleum products.

[0038] Implementation of the invention

[0039] An analysis of the physicochemical properties of a known oil impregnation composition (prototype) and the proposed compositions of oil impregnation antiseptics for wood preservation was carried out in laboratory conditions (see Table 3).

[0040] The proposed petroleum-based wood preservatives were prepared by simply mixing the following components: "base plus diluent plus fungicide plus corrosion inhibitor (biocide)." The fungicide (a reaction product of metal salts (copper or zinc) with saponified naphthenic acids—naphthenates and / or resinates of metal salts (copper or zinc)—and the inhibitor-biocide—a reaction product of fatty amines with various mixtures of higher unsaturated carboxylic acids and their esters—are used as finished products.

No phenols.

[0051] As follows from the given examples 1-8, the proposed antiseptic liquid (composition for wood preservation), in comparison with the prototype, has a lower viscosity and high penetrating ability, a high flash point in an open crucible, which allows to simplify the technology of its application and ensure higher quality of wood impregnation.

[0052] In addition, the proposed composition has a higher microbiological resistance and a high level of wood protection due to the combined use of a fungicide and a biocide inhibitor.

[0053] The examples also illustrate the achievement of the same technical result when using copper or zinc naphthenate, or copper or zinc resinate separately, as well as in a mixture, in various combinations of them.

[0054] Thus, based on the above examples, it is obvious that the proposed method of wood preservation has the following advantages in comparison with the prototype:

[0055] 1. All obtained and tested compositions of the oil-based wood preservative impregnation are fundamentally new and fully comply with the requirements of GOST 20022.5-99 "Wood Protection. Autoclave Impregnation with Oily Preservatives" for all key quality indicators (flash point, viscosity, density, volume fraction of water).

[0056] 2. One of the main requirements for wood preservatives, according to GOST 20022.5-99 "Wood Protection. Autoclave Impregnation with Oily Preservatives," is the kinematic viscosity of the preservative. The kinematic viscosity of the preservative should be no more than 5 mm. 2 / s, the proposed compositions for wood preservation have a kinematic viscosity depending on the ratio of the initial components within the range of 3.24-4.98 mm 2 / s, which indicates their good penetrating (impregnating) ability.

[0057] 3. The proposed wood preservation composition contains aromatic hydrocarbons with high protective properties. The addition of a fungicide—a reaction product of metal salts (copper or zinc) with saponified naphthenic acids (naphthenates and / or resinates of metal salts (copper or zinc)—and an inhibitor (biocide)—a reaction product of fatty amines with various mixtures of higher unsaturated carboxylic acids and their esters—increases the protective capacity of the petroleum preservative compared to the prototype.

[0058] 4. The invention can be used for preserving wood, in particular in construction and other industries, in order to protect them from damage by fungi and bacteria (biodamage).

[0059] 5. The proposed method for wood preservation contains abundant petroleum fractions and is classified as hazard class 3 (low hazard). It expands the raw material resources of oil-based preservatives through the rational use of petroleum products.

[0060] 6. The obtained results are achieved only in the aggregate of the essential features of the proposed technical solution of the invention.
