Description
Technical Field
The invention belongs to the technical field of coatings, and particularly relates to a water-based flame-retardant coating for a fireproof cotton textile rope.
Background
Textile cords are textile materials made by twisting a plurality of yarns or threads and are widely used, including clothing, household and specialty materials, and the like. Cotton is one of the most commonly used textile materials, and compared with some synthetic polymer fibers, the main advantages of cotton fibers are fluffiness, softness, temperature sensitivity, no itching feeling (the fiber ends are extremely thin), moisture dispersion, no static electricity under ordinary environment, and no generation of molten drops during combustion. However, the textile rope made of cotton fiber has the main disadvantages of flammability and environmental pollution in the combustion process, and limits the application of the cotton fiber textile rope in special textiles.
In order to reduce the inflammability of the material and improve the flame durability of the material, the flame-retardant method of the cotton textile rope is to react cotton with an organic flame retardant before the rope is formed and graft the material containing the flame-retardant component on the surface of the cotton textile rope; or the principle of layer-by-layer self-assembly is utilized to paste organic/inorganic flame-retardant components with opposite charges on the surface of the cotton textile rope, and a waterproof protective layer is coated on the basis of the organic/inorganic flame-retardant components.
Therefore, there is a need for a flame retardant coating for cotton textile ropes, which has a good flame retardant effect, is low in cost and is convenient to process.

The intumescent flame-retardant water-based paint has good flame retardance and dispersibility, and the flame-retardant and fireproof mechanism is as follows: during the combustion process, PVA and dipentaerythritol are quickly carbonized under the catalytic action of phosphoric acid and boric acid decomposed from ammonium polyphosphate and boric acid ester respectively, and meanwhile, ammonium polyphosphate can be decomposed into incombustible nitrogen-containing gas (NH) at high temperature3) When the gas escapes and passes through the carbon layer, the gas rapidly expands to form a thick protective layer, and kaolin and boron nitride are added into the coating to increase the compactness and the heat insulation of the expanded carbon layer, so that the internal cotton textile rope is protected.
Compared with the prior art, the invention has the beneficial effects that: the intumescent composite flame retardant prepared by the invention has good compatibility with the organic silicon emulsion, can be better fixed on a cotton textile rope, has good adhesion with the cotton textile rope, improves the water resistance of the flame retardant coating on the rope, and prolongs the service life of the cotton textile rope. In addition, the water-based flame-retardant coating can generate a thick expansion layer on the surface of the rope in the combustion process, has stronger fire resistance, widens the application field of the cotton textile rope, and improves the use value of the cotton textile rope. Tests prove that the limited oxygen index of the cotton textile rope treated by the coating can reach more than 35 percent, and the phenomenon of continuous open fire can not occur in a vertical combustion test. The cotton textile rope treated by the coating has the characteristics of good fireproof performance and less smoke.

Example 7
The intumescent composite flame retardant prepared according to the method provided by the example 1 is different from the method provided by the example 1 only in that the type of the polyvinyl alcohol used is PVA2099, and the prepared flame retardant is used for preparing the water-based flame retardant coating instead of the intumescent composite flame retardant in the example 3.

Test example 1
The flame retardant property test is carried out on the water-based flame retardant coating prepared in the embodiment 3-8, and the preparation method of the fireproof cotton textile rope comprises the following steps: firstly, the cotton textile rope passes through a sand frame, then is dipped in coating through a coating tank, then is rolled by two rollers, is dried through a high-temperature drying channel at 120 ℃, and finally is rolled at the speed of 20m/min to obtain the fire-resistant cotton textile rope, and meanwhile, a pure sample of the cotton textile rope which is not treated by the water-based flame-retardant coating is set as a reference, and the detection result is shown in table 1.
TABLE 1 flame retardancy test of aqueous flame retardant coatings
As can be seen from Table 1, the pure samples are very flammable, but after the samples are treated by the water-based coatings of the invention of the examples 3-8, continuous open fire does not appear under the heating of flame, and the limiting oxygen indexes are all over 35 percent. From the six examples it can be seen that the overall performance of example 4 is the best, and that example 3, 4 has a higher content of modified intumescent flame retardant than example 4, so that when the flame treated rope is tested it has a thicker intumescent layer, which is more favourable for the fire resistance of the rope, and in addition has a lower weight gain due to the use of less adhesive. The total intumescent flame retardant system of examples 3 and 5 was added in equal amounts, but example 5 contained more kaolin and boron nitride, which somewhat limited the expansion of the carbon layer and therefore the expanded thickness was seen to be less in the test results.
Test example 2
The flame-retardant water-based paint of the embodiment 3-8 is subjected to dispersion performance test, a control group is set during the test (the intumescent composite flame retardant in the embodiment 3 is replaced by equal amount of ammonium polyphosphate, and the rest is the same), and the test method comprises the steps of respectively measuring 100ml of the flame-retardant water-based paint in the embodiment 3-8 by using 100ml of test tubes, vertically placing the test tubes on an observation frame, and checking whether the paint in the test tubes is settled every 12 hours, wherein the results are shown in table 2.
TABLE 2 Dispersion Performance test of aqueous flame retardant coatings
As can be seen from Table 2, the control group has sedimentation within 12 hours, the dispersibility is the worst, the flame-retardant water-based coatings provided in examples 3 to 5 have good dispersibility, and have no sedimentation after 36 hours, while the intumescent composite flame retardants in examples 6 to 8 have slightly poor dispersibility, have no sedimentation within 24 hours, and have sedimentation within 36 hours as time goes on.
Test example 3
The method of test example 1 was used to prepare a fire-resistant cotton textile rope from the aqueous flame-retardant coating prepared in examples 3 to 8, the fire-resistant cotton textile rope was soaked in water for 12 hours and then taken out, after drying, the appearance of the coating film on the cotton textile rope was observed, and the flame-retardant performance test was performed, the test results are shown in table 3
TABLE 3 Water resistance of aqueous flame retardant coatings
As shown in Table 3, the water resistance of the fire-resistant cotton textile ropes in the examples 3 to 5 is better than that of the fire-resistant cotton textile ropes in the examples 6 to 8, after being soaked in water, the limiting oxygen index of the fire-resistant cotton textile ropes in the examples 6 to 8 is obviously lower than that of the fire-resistant cotton textile ropes in the examples 3 to 5, which indicates that the water-based fire-retardant coatings provided in the examples 6 to 8 are used for fire retardation of the textile ropes, the water resistance is poor, and the fire retardation effect after being soaked is obviously lower than that of the fire-resistant cotton textile ropes in the examples 3 to 5.
Finally, it should be emphasized that the above-described preferred embodiments of the present invention are merely examples of implementations, rather than limitations, and that many variations and modifications of the invention are possible to those skilled in the art, without departing from the spirit and scope of the invention.
