Description

Technical Field

[0001] The invention belongs to the technical field of polyurethane foam composite materials, and in particular relates to an aging-resistant high-performance polyurethane foam composite material and a preparation method and application thereof. Background Art

[0002] Pipeline transportation is widely used due to its large capacity, low cost, safety and reliability, strong continuity, low energy consumption and high efficiency. However, its disadvantage is that as the transportation time increases, a large amount of dirt will adhere to the inner wall of the pipeline, increasing the resistance to transportation and causing problems in the transportation process. Therefore, it is very necessary to clean the inner wall of the pipeline.

[0003] At present, CN107501521A discloses a polyurethane foam composition used in pipe inner wall cleaners and its preparation method. It uses a variety of polyether polyols as raw materials. The prepared products have good elasticity and excellent hydrolysis resistance, but the mechanical properties of the products are poor. CN116655873A discloses a composite material for making a pipe cleaning head and its preparation method. By mixing polyester polyols and polyether polyols, a polyurethane composite material is prepared for use in pipe cleaning heads. The obtained product has good mechanical properties, especially wear resistance. In short, the polyurethane foam composite material has a good application effect in pipe cleaners, but the density of the pipe cleaners made by the above two patents is 200kg / m 3 The density is suitable for making medium-sized and smaller pipe cleaners. When making large-sized pipe cleaners, the weight is large, which is not conducive to practical use.

[0004] In order to reduce the density of the product and prepare a pipe cleaner suitable for large diameter pipes, the common method is to increase the amount of water or add some 141B foaming agent, but full water foaming affects the performance of the product, 141B foaming agent is highly polluting, and the products made by these two methods are easy to shrink, unstable in nature, and have poor use effects. Therefore, it is necessary to develop aging-resistant high-performance polyurethane foam combinations to meet the requirements of large diameter (Φ>1000mm) pipe cleaning. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned defects of the prior art, provide an aging-resistant high-performance polyurethane foaming composite material, meet the needs of large-diameter pipeline cleaning, and apply it to a low-density pipeline cleaner, which has the advantages of low density, aging resistance, excellent mechanical properties, good stain resistance, etc. The present invention also provides a preparation method thereof.

[0085] Comparative Example 1

[0086] This comparative example is the same as Example 1, except that AFS-L-1011 in component A is replaced with an equal amount of PE-Y173, and the remaining steps are the same.

[0087] Comparative Example 2

[0088] This comparative example is the same as Example 1, except that AFS-L-1001 in component B is replaced by an equal amount of PE-2316, and the remaining steps are the same.

[0089] Comparative Example 3

[0090] This comparative example is the same as Example 2, except that 10 parts of SA5000-D in component A are removed, the mass fraction of H2O is increased from 2.5 parts to 3.5 parts, and the remaining steps are the same.

[0091] Comparative Example 4

[0092] This comparative example is the same as Example 3, except that the mixture of A33:FOCAT-8003M=1:0.5 in component A is replaced with an equal amount of A33, and the remaining steps are the same.

[0093] The performance of the aging-resistant high-performance polyurethane foam composite materials prepared in Examples 1-5 and Comparative Examples 1-4 was tested. The test results are shown in Table 1.

[0094] Hardness and tear strength were tested according to GB / T 2411-2008 and GB / T 10808-2006 respectively, and the test standard for tensile strength and elongation was GB / T 6344-2008; the dimensional retention rate was tested according to the standard GB / T 10801.2-2018, dimensional retention rate (%) = product volume after use / product volume at mold opening × 100%, the higher the dimensional retention rate, the more stable the product is, the less likely it is to deform, and the practicality of the product is maintained; the water contact angle was tested using the method in ASTM D7490-2013; the aging test conditions were: temperature 80°C, relative humidity 80%, left for 48 hours, and the tensile strength change rate and elongation change rate of the product were tested after aging; the pollution resistance test was to mix edible oil and dark soy sauce in a mass ratio of 5:2, immerse the product in it for 10 minutes, bake it in an oven at 60°C for 30 minutes, and then wash it in clean water to measure the color difference on the surface of the product.

[0095] Table 1 Test results

[0096]

[0097] It can be seen from the test results of Examples 1-5 and Comparative Examples 1-4 in Table 1 that, compared with Comparative Examples 1 and 2, the product in Example 1 has a larger water contact angle, a smaller change in elongation and tensile strength after aging, and a better stain resistance test effect, which indicates that the addition of methyl fluorosilicone oil and hydroxy fluorosilicone oil improves the stain resistance and hydrophobicity of the product, and the strong hydrophobicity of fluorine atoms slows down the aging of the product and extends the service life of the product; secondly, Comparative Examples 1 and 2 further show that when AFS-L-1011 and AFS-L-1001 exist at the same time, the stain resistance and anti-aging performance of the product are better, and the two fluorosilicone oils work together to enhance the performance of the product.

[0098] Compared with Example 2, Comparative Example 3 uses water instead of the physical foaming agent SA5000-D to produce a product with lower density, but the mechanical properties of the product are significantly reduced; at the same time, the product made by the all-water system has a low dimensional retention rate and unstable properties. Combined with the test results of Example 2, it is shown that adding an appropriate amount of physical foaming agent can increase the stability of the product and improve the life of the product.

[0099] Compared with Comparative Example 4, Example 3 uses a mixture of A33 and FOCAT-8003M as a catalyst, which is beneficial to increase the surface thickness of the product. At the same time, the thicker skin is also beneficial to improving the mechanical properties, hydrophobicity and stain resistance of the product.
