The invention relates to the field of light industry, and more specifically to processing and rope products used in industrial fisheries and other sectors of the economy. A method of processing and rope products (patent RF №2230141, IPC D06 3/06, D06M 13/02, D02J 3/18, publ. 10.06.2004, BI No. 16), including the application process of the drug through the gradual unwinding of the product, dipping and pulling it through the process the drug at a speed which provides the desired depth of impregnation, and the temperature of the process of the preparation is maintained at a level (120±10)°C.
The disadvantage of the method described above are technological difficulties for maintaining the temperature of the impregnation product in the molten wax at a temperature (120±10)°C. When the temperature drops below the specified limit increases the gain of impregnation, and at temperatures above 140°there is a risk of decomposition of the wax, which is reflected in the decline in the quality of the treated products.
A method of processing fishing sitematerials composition-based latex (copyright certificate №1636492, IPC 5 D06P 1/52, D06M 15/16, publ. 23.03.1991, BI No. 11), including pulling sitematerials cooked through technological preparation based latex BSM-65, representing a mixture of a latex of butadiene is Teroldego copolymer with a mass fraction of styrene units 60-65%, stable partynator potassium and water solution alkylresorcinol resin with the addition of the dye disperse black mixtures or mixtures of nigrosine with soot and water for 2-8 min, the temperature of which is equal to 18±5°C. After impregnation metamaterial subjected to preliminary drying, using the blowout air temperature of 40±5°With over 10±5 min. Then carry out a two-stage drying at a temperature of 70±10°at the first stage 110 and±10°in the second stage, soaking for 5-10 minutes at each stage. At the final stage, carry out the heat treatment at 190±10°C for 1.0 to 1.5 minutes
The disadvantage of the method described above to handle and rope products is the fact that the bulk impregnated ropes and cords with a diameter of 10-16 mm not dry after drying at 40±5°With over 10±5 min and at the first stage of drying at 70±10°C for 5-10 min, therefore, falls into the second zone drying temperature of 110±10°C, the wet latex inside the ropes boils and squeezed on the surface of the product in the form of bubbles, which the music industry in the curing oven at 190±10°forming roughness on the surface of the product, this worsening of the quality of finished products.
The disadvantage is you who Oka stiffness impregnated with this composition of ropes and cords, used for the construction of the cable part of the large trucks and their color only in black color. Currently, the fishing use of the cable layer in trawls as unpainted and painted in different colors, depending on the requirements. This is useful in the manufacture of trawls when connecting the top, bottom and side surfaces of trawls, and especially when you repair them in the event of rush some parts during operation.
The invention solves the problem of decreasing the hardness of saturated and rope products (ropes, cords, ropes and others), maintaining their flexibility and plasticity, creating opportunities to paint and rope products in different colors and are aimed at improving the quality of soaked and rope products, expanding their range due to the possibility of impregnation of ropes and cords with a diameter of 8-18 mm
The technical problem is solved due to the fact that in the known composition for impregnation fishing metamaterials, including latex BSM-65 grade a or B and the water injected wax emulsion VE-40, in the following ratio of the components of dry matter, wt.%:
|latex BSM-65 grade a or B||17-25|
|wax emulsion VE-40||1,5-2,8|
If necessary, coloring and rope products in the proposed composition is administered dye and latex BSM choose grade B in the following ratio of the components of dry matter, wt.%:
|latex BSM-65 grade B||17-25|
|wax emulsion VE-40||1,5-2,8|
The ratio of the components is verified.
If necessary, a collaborative process of impregnation and dyeing in black, brown or another dark color brown latex BSM-65 brand And not an obstacle to its use. When it is necessary to paint the ropes, going for the construction of large trucks in bright colors: yellow, red, blue or green, it is essential that the latex film was colorless, which is provided by the use of latex BSM-65 grade B, not tucked alkylresorcinol resin, i.e. colorless.
In the composition used wax emulsion VE-40 (TU RB 600125053.016-2003) or emulsion derived from the emulsion of wax, representing a mixture of non-volatile residue, wt.%:
|wax AA-30 (polyethylene)||33,9|
As a material used in the manufacture of fishing and rope products, the largest volume occupied polyamide fibers. Due to the dense structure and high orientation polyamide fiber dyeing their dyes is carried out at elevated temperature and using assistive and surfactants for better wetting and penetration of the dye into the fiber. Included in the latex and a wax emulsion surfactants (sintana-10, ALM, triethanolamine, wax) play the role of auxiliaries in dyeing, so when it is saturated polyamide and rope products latex-wax composition entered into the acid dye is instantaneous wetting and penetration of the impregnating composition between fiber products, as the dye in the fibre structure. Acid dyes such as acid orange fade resistant and acid red solid have a high degree of affinity with the polyamide fiber and low aggregative properties, so that they dyed polyamide fiber at relatively low temperatures. Further gradual agrew during drying and subsequent heat treatment promotes fixation of the dye on the fiber. As the dye can be used and disperse dyes under the same mode of impregnation, drying and heat treatment.
The way to handle and rope products includes applying technological preparation by dipping and pulling the product through it, pre-drying the product at a temperature of 40±5°C, two-stage drying and final heat-treated at this temperature for the first stage of drying is chosen within the 60±10°for the second - within 80±10°and carry out drying at both stages within 6-18 min, and heat treatment is carried out at a temperature of 130±10°within 1.5 to 3.5 minutes
These temperature regimes of drying and heat treatment obtained experimentally.
Technology of preparation of the proposed structure is as follows.
In stainless steel tank with a volume of 1.3 m3equipped with a lid and a mixer, pour the latex BSM-65 grade B (colorless) with a dry matter content of 50% in the amount of 400 l (determination of solids is carried out on THE 38.103579-85).
When a mechanical stirrer in the container of latex is poured 545 litre of water and stirred for at least 10 minutes Then in the same capacity, also when the stirrer is served wax emulsion 40%concentration of nonvolatile substances in quantities of 50 l and mixed for not less than 10 is in. In the finished composition is injected dye acid orange lightfastness
in the amount of 2 kg, pre-diluted in 5 liters of water, heated to ˜50°C.
The thus prepared latex-wax composition is poured into an impregnating bath of impregnating and drying unit type IFL-1000 for implementing the method of impregnation materials.
A specific example of implementation of the proposed method of treatment and rope products offered by the structure.
Be impregnated and rope products with a diameter of 16 mm, connected in a continuous stream, stretched through the impregnating bath filled work impregnating composition in % of the volume to prevent transfusion over the edge when immersed impregnated materials. The speed of pulling products through an impregnating bath was 1.2 m/min
The impregnated product was then admitted into the chamber drying airflow, where he maintained a temperature of 40°and passed through it for a period of 7.5 minutes and Then the product was sent in the 1st drying chamber with the set temperature at 60°that the product was held for 18 min and did in the 2nd drying chamber, where the temperature was maintained 90°in which the product was 18 min, after which he entered the chamber termopan the TCI with a temperature of 130° With which he served for 3.5 minutes Dried so the product had a smooth glossy surface without Nalimov and fuzz. A cross section of the impregnation visible across the slice, the structural components of the rope strands, kabalci, strand) is not broken.
Optimal regimes for rope diameter 16 mm are presented in examples 2, 3, 4, which correspond to the above-described method.
Physico-mechanical properties of the rope diameter 16 mm, impregnated with latex BSM-65 grade are presented in table 4. These figures do not differ from the performance of the rope impregnated with latex BM-65 marks, combined with the dye.
Table 1 presents the physical and mechanical properties of the rope diameter 16 mm, treated with the proposed structure. The table clearly shows the dependence of physical-mechanical indicators on the number of latex and a wax emulsion in the composition.
|№ p/p||Content in dry matter, wt.%||Physico-mechanical properties of the rope diameter 16 mm|
|Latex type BSM-65 (grade B)||Wax emulsion||Dye||Water||Gain impregnation, %||Water absorption, %||The hardness, h, cm2||Vymyvaemosti impregnation after 2 hour wash||The intensity of the color ball.|
|Before washing||After washing|
As can be seen from table 1 is optimal for use are compounds in examples 2, 3, 4. With the increase of the dry matter content of the latex increases the gain of impregnation, reduced water absorption and vymyvaemosti, but simultaneously increases the stiffness of the treated products.
With the introduction and increased the percentage of wax stiffness soaked and rope products decreases, and:vymyvaemosti impregnation is maintained at a low level. Compared with the composition is analogous to the stiffness of the rope is reduced in 2 times. The intensity of color after washing is reduced by one point, but the color remains bright enough. Vymyvaemosti impregnation up to 10% as a result of numerous experiments is considered a good indicator.
In table 2 clearly shows the dependence of the appearance soaked ropes with a diameter of 16 mm from the processing modes in accordance with the proposed method.

|6||40°||7,5||90||18||110||18||180||3,5||Hard with a large number of dried bubbles latex|
In table 3 comparative physico-mechanical properties of polyamide rope diameter 16 mm impregnated and impregnated with the following composition:
- melt the wax;
- latex BSM-65;
- proposed composition.
|Melt wax||Latex BSM-65 with a dry matter content of 25 wt.%||The proposed composition|
|Linear density, ctex||145||184||171||170|
|The breaking load, kgf||5525||5330||5440||5430|
|Gain impregnation, %||20,2||10,0||9,0|
|Leaching impregnation after 2 hours of washing||2,8||7,0||5,6|
|The hardness, h, cm2||32,0||50,0||65,0||45,0|
|The coefficient of hydrodynamic resistance||0,57||0,046||0,055||0,039|
From table 3 it follows that the physical and mechanical properties of ropes impregnated proposed composition, linear density, the breaking load and the absorption close to the ropes impregnated with latex BSM-65, but less hard and have a very low coefficient of hydrodynamic resistance, and therefore, have better properties.
