Description

Technical Field

[0001] The invention belongs to the technical fields of polymer synthesis technology and filter materials, and particularly relates to a method for preparing a reinforced resin for high-temperature resistant lubricating oil glass fiber filter material. Background Art

[0002] Lubricating oil plays the role of lubrication, cooling, cleaning, sealing, rust prevention, power transmission, vibration reduction and noise reduction in the engine lubrication system of mechanical equipment such as aircraft and ships, thereby ensuring the efficient and stable operation of the equipment and extending its service life. It is known as the "blood" of mechanical equipment. High-temperature lubricating oil filter media need to cope with extreme temperatures (≥200°C), chemical corrosion and dynamic filtration challenges. The material must be resistant to high-temperature aging, have high filtration accuracy (≥99% interception of 5μm particles) and chemical stability, while balancing pressure drop and dust holding capacity. Its core application scenarios include harsh environments such as engines and turbines.

[0003] Glass fiber media can operate stably and long-term at temperatures between 200 and 300°C, effectively intercepting tiny particles (≥99% filtration efficiency). It exhibits high-temperature resistance, chemical stability, high mechanical strength, and low pressure drop. Its advantages include long life, resistance to oil oxidation, and low energy consumption. Therefore, glass fiber filter material is the primary material for lubricating oil filtration media. However, the low surface hydroxyl content of glass fiber results in poor bonding strength and a loose structure in the resulting glass fiber base paper. In practical engineering applications, the glass fiber base paper is typically reinforced with resin. Only after this reaction can the resulting glass fiber filter material meet application requirements. Optimizing the fiber shedding prevention process and regularly monitoring the pressure differential and oil contamination status are required to ensure long-term reliability. Traditional reinforcing resins for lubricating oil glass fiber filter media are mostly thermoplastic or thermosetting acrylic resins. Thermoplastic acrylic resins have a low degree of crosslinking, resulting in a decrease in strength after the resin swells and softens in oil at high temperatures, making them unable to meet the high-temperature resistance requirements of applications.

[0004] Patent US2015174509A1 reports a filter medium in which a layer of glass fiber is impregnated with 5% thermoplastic acrylic resin. However, the filter material has a large flow pore size and serves only as a pre-filtration layer. Furthermore, the resin bonding strength is low, and the glass fiber easily falls off into the oil, exacerbating contamination.

[0005] Patent CN110066359B provides a water-soluble thermosetting acrylic resin that can impart excellent tensile strength, elongation at break, and oil and high-temperature resistance to glass fiber filter media. However, this system has a high curing temperature and is susceptible to aging at temperatures exceeding 150°C, resulting in reduced strength and pulse resistance.

[0006] Patent CN116874722A discloses a silicone / polyurethane / epoxy composite resin emulsion. When applied to glass fiber filter media, this emulsion imparts excellent tensile strength and retention, resulting in enhanced oil and high-temperature resistance. However, this system, a simple compound of silicone / polyurethane / epoxy resins, fails to maximize the performance of all three. Furthermore, the physical compounding process, without further chemical crosslinking, is not conducive to application in sustained high-temperature environments.

[0007] With the changes in the application scope and working environment of the lubricating oil system, higher requirements are placed on the high-temperature oil resistance and bonding performance of the bonded resin. The currently disclosed filter material products or reinforced resins cannot meet the requirements of practical application processing and durability. Therefore, there is an urgent need to find a lubricating oil that can withstand higher temperatures and at the same time improve the processing performance of the enhanced filter material and a durable and environmentally friendly reinforced resin system.

Simultaneously, an amide-type high-temperature crosslinking agent is introduced into the polymerization reaction, thereby forming a triple crosslink of epoxy, amide, and siloxy bonds, forming a three-dimensional crosslinked structure, thereby enhancing the cohesive force between the entire resin molecules and forming multiple crosslinks during the coating curing process. The increased crosslinking density of the coating enhances the impact resistance of the coating, thereby resolving the various performance issues of the glass fiber paper under persistent high-temperature conditions and improving its durability. The treated glass fiber paper can be stably stored for a long time, thus facilitating industrial continuous production.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] The experimental methods in the following examples are conventional methods unless otherwise specified. The raw materials, reagents, etc. used in the following examples are commercially available products unless otherwise specified.

[0047] Examples 1-4

[0048] Examples 1-4 disclose a reinforced resin for high-temperature resistant lubricating oil glass fiber filter material. The raw material composition is shown in Table 1 and is prepared by a method comprising the following steps:

[0049] Step (1) Synthesis of epoxy-modified polyurethane:

[0050] Add dehydrated epoxy polyester polyol and catalyst to a reactor, heat to 65-75°C, add isocyanate and stir evenly, react for 2-4 hours, slowly dropwise add hydrophilic chain extender DMPA and add solvent to adjust viscosity, continue to react for 1-3 hours, add hydroxy acrylate, heat to 75-85°C, keep warm for 2-4 hours, cool to 40-45°C after end-capping, add TEA to neutralize for 0.5-1.5 hours, then add deionized water and disperse at high speed for 0.5-1.5 hours, discharge, and remove residual solvent by rotary evaporation to obtain an epoxy-modified polyurethane aqueous emulsion with a solid content of 50%;

[0051] Step (2) Synthesis of Enhanced Resin:

[0052] After the synthesized epoxy-modified polyurethane aqueous emulsion, vinyl silicone oil, crosslinking agent, cosolvent, water, and composite emulsifier are dispersed at high speed, 1 / 3 of the mixed emulsion is added to a bottle, 1 / 3 of the initiator is added dropwise, and the mixture is heated to 70-80°C. The rotation speed of the electric stirrer is set to 100-200 r / min. After the system reacts for about 15-20 minutes, a blue phenomenon will appear; the remaining mixed emulsion and the remaining initiator are added dropwise separately, and the dripping is controlled to be completed continuously within 2.5-3.5 hours. After the dripping is completed, the system is heated to 80-90°C, kept warm for 0.5-1.5 hours, and finally cooled and discharged to obtain a white emulsion with a slightly light blue light and a solid content of 40%. A measured amount of water-based curing agent Wanner H123 is added for compounding to form a reinforced resin emulsion.

[0053] The reinforcing resin emulsion is compounded according to the theoretical value that the epoxy equivalent is equal to the active hydrogen equivalent.

[0054] The initiator is a mixture of 0.2 g KPS and 10 g water.

[0055] The reinforced resin for high temperature resistant lubricating oil glass fiber filter material can be obtained by completing the above steps. The results are shown in Table 1.

[0056] Table 1 Composition of Reinforced Resin Raw Materials in Examples 1-4

[0057] Table 1

[0058]

[0059]

[0060] As shown in Table 1, Examples 1-4 can form stable and blue-light emulsions within the scope of the present invention. C 2200 (Covestro), E-300 (Huntsman), by replacing isocyanate with diphenylmethane diisocyanate and hexamethylene diisocyanate, replacing the cosolvent with dipropylene glycol and dipropylene glycol monomethyl ether, and replacing the initiator with ammonium persulfate, can also obtain a reinforcing resin for high-temperature resistant lubricating oil glass fiber filter material that meets the above requirements.

This is the characteristic peak of polyurethane and amide. 1250cm -1 At the peak, and 800cm -1 Nearby is the characteristic absorption peak of epoxy. 1000-1100cm -1 The interval corresponds to the Si-O-Si asymmetric stretching vibration peak.

[0062] Comparative Examples 1-3

[0063] Comparative Examples 1-3 prepared a reinforced resin for high-temperature resistant lubricating oil glass fiber filter material. The raw material composition is shown in Table 2. The preparation was carried out according to the same steps and methods as in Examples 1-4. The results are shown in Table 2:

[0064] Table 2: Comparative Example Raw Material Composition

[0065]

[0066]

[0067] Examples 5-8

[0068] Examples 5-8 and Comparative Examples 4-6 respectively prepared high-temperature resistant lubricating oil glass fiber filter materials using the reinforced resins for high-temperature resistant lubricating oil glass fiber filter materials of Examples 1-4 and Comparative Examples 1-3.

[0069] Mix 3g of the reinforced resin emulsion prepared in Examples 1-4 or Comparative Examples 1-3 with 98g of water and stir until uniform. Lay the formed micro-glass fiber paper flat and immerse it in the diluent for 30 seconds. Remove it, remove it, and cure it at 150°C for 15 minutes to obtain a high-temperature lubricating oil-resistant glass fiber filter material. Maintain a sizing agent at 4-6%.

[0070] Test Case

[0071] The performance of Examples 1-8 and Comparative Examples 1-6 was tested using the following method:

[0072] 1. Emulsion particle size test

[0073] The particle size of the reinforced resins prepared in Examples 1-4 and Comparative Examples 1-3 of the present invention was tested by using a Mastersizer 2000 laser particle size analyzer (Malvern, UK) to test the size and distribution of the latex particles. The test results are as follows: Figure 2 shown.

[0074] 2. Stiffness test

[0075] The stiffness test was performed in accordance with GB / T 22364-2018. The stiffness of the glass fiber filter materials of Examples 5-8 and Comparative Examples 4-6 was tested using a bending stiffness tester. The sample length was 70 mm, the bending length was 50 mm, and the bending angle was 15°.

[0076] 3. Tensile strength

[0077] The tensile strength test was performed in accordance with GB / T 12914-2023. The tensile strength and tensile strength retention of the glass fiber filter materials of Examples 5-8 and Comparative Examples 4-6 were tested using a tensile strength meter. The sample length was 100 mm and the width was 15 mm.

[0078] 4. High temperature resistant oil performance test

[0079] The glass fiber filter materials prepared in Examples 5-8 and Comparative Examples 4-6 were immersed in aviation lubricating oil at an oil temperature of 200°C for 48 hours so that both sides could be fully exposed to the oil. After being taken out, the surface lubricating oil was gently wiped off with oil-absorbing paper, and the filter materials were then washed three times with petroleum ether to wash off the residual lubricating oil. Finally, they were placed in an oven at 150°C and dried to constant weight before the stiffness test.

[0080] 5. Durability-Failure Test

[0081] Failure testing is measured using test time and the sample's stiffness retention rate. In a failure test, the sample is first tested for stiffness after preparation, designated X0. The sample is then placed in a storage environment at 85±2°C and 85±2% relative humidity. The stiffness is measured multiple times at regular intervals, designated X1, X2, X3, and so on, at regular intervals. The stiffness retention rate is calculated as the ratio of the test stiffness values ​​(X1, X2, X3, and so on, Xn) to the initial stiffness value (X0). A stiffness retention rate of less than 80% is considered failure. Failure testing can reflect the durability of filter materials.

[0082] The glass fiber filter papers prepared in Examples 5-8 and Comparative Examples 4-6 were tested for pleating performance. The test results are shown in Figure 3 and Table 4 below:

[0083] Table 3: Performance data of glass fiber filter papers prepared in Examples 5-8 and Comparative Examples 4-6

[0084]

[0085] As shown in Table 3, the initial tensile strength, stiffness and durability of ordinary polyester polyols are all decreased compared with Example 5. This is because there is no curing agent, which affects its cross-linking. Compared with Example 5, the amide cross-linking agent is less during the secondary synthesis, and the initial tensile strength and stiffness are all decreased, and the durability decreases significantly. After 500h, the stiffness retention rate is halved. This shows that the introduction of the amide cross-linking agent can improve the cohesion between the entire resin molecules and improve durability. Compared with Example 5, the amount of siloxane used is reduced, the initial tensile strength decreases, and the stiffness increases, indicating that the epoxy resin accounts for too high a proportion, making the cured film too hard and brittle, resulting in poor tensile strength and a decrease in durability.

[0086] Table 4: High temperature oil resistance performance data of glass fiber filter paper treated with reinforced resin emulsion

[0087]

[0088] As can be seen from the results in Table 4, compared with Example 5, the tensile strength retention rate of ordinary polyester polyol after 200°C high-temperature oil is only 41.82%, and the stiffness retention rate is 46.88%. Epoxy polyester plays a very important role in high temperature resistance. Compared with Example 5, the amide cross-linking agent is less during the secondary synthesis. After 200°C high-temperature oil, the tensile strength retention rate is only 67.11%, and the stiffness retention rate is 59.46%. This shows that the introduction of the amide cross-linking agent can form multiple cross-links with epoxy and siloxy bonds during the coating curing process, thereby increasing the cross-linking density of the coating and enhancing the high-temperature resistance of the coating. Compared with Example 5, the amount of siloxane used is reduced. After 200°C high-temperature oil, the tensile strength retention rate and stiffness retention rate are about 50%, indicating that the proportion of epoxy resin is too high, making the cured film too hard and brittle, and the adhesion is poor.
