Description

Technical Field

[0001] This invention relates to the field of polymer material additives, and more specifically, to a water-dispersible reactive light stabilizer and an aqueous polymer material. Background Technology

[0002] In recent years, the technology of polymer materials has developed rapidly, resulting in a variety of materials with unique properties, providing greater development space and more possibilities for the progress of modern society. Polymer materials are ubiquitous and have extremely wide applications, but most of them are directly exposed to the atmosphere. Light, air, carbon dioxide, water, and biological organisms can all cause the aging of polymer materials, further affecting their performance or service life, thus greatly limiting their applications.

[0003] The aging of polymer materials is mainly due to the degradation of polymer chains, and the primary aging mechanism for materials used at room temperature is photo-oxidative degradation. Adding light stabilizers, such as UV absorbers and hindered amine light stabilizers, is the main way to prevent photo-oxidative degradation. UV absorbers can absorb or shield the harmful ultraviolet rays in the 280–450 nm wavelength range from sunlight and fluorescent light sources without undergoing any changes themselves. Hindered amine light stabilizers stabilize polymers through multiple pathways, including capturing free radicals generated during polymer photo-oxidation and degradation, decomposing alkyl hydrogen peroxide, and quenching excited-state energy. Hindered amine light stabilizers have a good inhibitory effect on the photo-degradation reaction of polymer materials and are currently the most widely used and efficient light stabilizers in the field of polymer anti-aging. Many studies have shown that UV absorbers (UVA) and hindered amine light stabilizers (HALS) have a synergistic effect, significantly improving the anti-aging effect of polymers. Therefore, the combined use of UVA and HALS is widely used in the field of polymer materials.

[0004] However, with continuous social development and increasingly stringent regulatory and environmental requirements in various countries, materials containing solvents, especially solvent-based coatings, contain large amounts of volatile organic compounds (VOCs) harmful to human health. Therefore, environmentally friendly water-based coatings, powder coatings, UV-cured coatings, water-based adhesives, and water-based inks are rapidly developing, and their proportion in industry products is increasing year by year. The requirements for the anti-aging properties of these materials are also constantly rising. Therefore, to adapt to new requirements, reduce VOC emissions, and meet multiple needs and processing technologies, the need for water-based UVA and HALS composite light stabilizers in environmentally friendly water-based coating systems is imperative. However, water-based UVA and HALS composite light stabilizers often encounter the following problems:

[0005] First, the issue of water dispersibility: Traditionally, UVA and HALS are added to polymer materials as additives. They are generally small or high molecular weight compounds that are hydrophobic and do not disperse evenly in water. They are easily soluble in organic solvents and generally need to be dissolved with a co-solvent before being added to water-based coating systems. This also brings the harm of VOCs.

[0006] Secondly, long-lasting effect: Under normal usage conditions, the combination of UVA and HALS provides good long-lasting protection for polymer materials. However, under conditions such as high temperature and environmental corrosion, traditional UVA and HALS will be lost through physical means (evaporation, migration, dissolution), and the concentration of light stabilizers in the material will gradually decrease, eventually failing to protect the material and leading to aging and degradation.

[0007] If UVA and HALS are designed as reactive, and the light stabilizer is chemically crosslinked to the polymer chain, the aforementioned material longevity issues can be resolved, and a long-term protective effect can be achieved. However, although some reactive UVA and reactive HALS compound products exist, there are very few reactive light stabilizers for aqueous systems to adapt to the development trend of aqueous polymer systems.

[0008] In view of this, the present invention is hereby proposed. Summary of the Invention

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] As described in the background section of this invention, there are few reactive light stabilizers used in aqueous systems. This is partly because reactive UVA and reactive HALS emulsifications have poor water dispersibility, making it impossible to form a stable and uniform aqueous dispersion. Furthermore, the adaptability and longevity issues faced by these materials have arisen with societal development needs and advancements in materials technology, and water-based formulations have not yet received sufficient attention.

[0032] To address the above problems, this invention provides a water-dispersible reactive light stabilizer, comprising: a first component: a reactive hindered amine light stabilizer and / or a reactive ultraviolet absorber; wherein the reactive hindered amine light stabilizer is... R1' is a C1-C10 alkyl group; the reactive ultraviolet absorber is... R1, R2, R3, and R4 are each independently selected from C1 to C4 alkyl groups, and R5 is selected from C8 to C20 alkyl groups or mixed alkyl groups; the second component is an emulsifier; the emulsifier is at least two nonionic surfactants, or simultaneously includes at least one anionic surfactant and at least one nonionic surfactant; the anionic surfactant is a sulfonate anionic surfactant or a phosphate ester anionic surfactant; the optional third component is a co-emulsifier; and when the first component contains a reactive ultraviolet absorber, the water-dispersible reactive light stabilizer must contain the third component.

[0033] Both are liquids at room temperature and are more easily and stably dispersed in water with the help of emulsifiers and optional co-emulsifiers. Therefore, the water-dispersible reactive light stabilizer provided by this invention has good compatibility with water-based polymers, can be stably dispersed in water-based polymers without the need for co-solvents, fully ensuring the environmental friendliness of water-based polymers, with no VOC hazards, thereby expanding the application range of reactive composite light stabilizers.

[0034] and, The structure retains the low-basic N-OR type matrix, with a reactive hydroxyl group introduced at the other end. The hydroxyl group can chemically crosslink with functional groups in polymer materials, such as isocyanate groups in polyurethane materials, free amine or ether bonds in amino resins, and epoxy groups in epoxy materials. Ultimately, the small-molecule hindered amine light stabilizer is bonded to the matrix polymer chain. This is especially true when reactive hindered amine light stabilizers... and reactive ultraviolet absorbers When used as the main components of light stabilizers, both have good compatibility and, when applied to water-based polymer materials, exist in a chemically linked form, exhibiting better long-lasting properties. They are less prone to volatilization, migration, and dissolution, thus providing long-term and effective protection for polymer materials.

[0035] Emulsifiers possess both lipophilic and hydrophilic groups, which adsorb onto the interface between two phases, reducing surface tension and forming an interfacial film. This film protects the dispersed phase droplets, preventing them from coalescing during Brownian motion. Droplet coalescence (which disrupts stability) presupposes the rupture of this interfacial film; therefore, the mechanical strength of the interfacial film is one of the main factors determining emulsion stability. The hydrophilic / lipophilic balance (HLB) value, molecular structure, and content of the emulsifier all affect the emulsification effect. The HLB value is related to the emulsifier's hydrophilicity / lipophilicity, as well as its surface tension, interfacial adsorption, emulsifying properties, and basic properties of the emulsion such as stability, dispersibility, solubility, and detergency. It also relates to the emulsifier's application performance. Lipophilic emulsifiers have lower HLB values, while hydrophilic emulsifiers have higher HLB values. The hydrophilic / lipophilic inflection point (HLB) is 10. An HLB value less than 10 indicates lipophilicity, while a value greater than 10 indicates hydrophilicity. The charge of the emulsifier and the polarity of the emulsified oil phase affect the spatial, electrical, or mechanical barriers between the dispersed phase droplets, further affecting the droplet size and the stability of the aqueous dispersion.

[0036] To create a more stable aqueous dispersion system for water-dispersible reactive light stabilizers, making them more suitable for waterborne polymer materials, in a preferred embodiment, each nonionic surfactant is independently selected from the following series: octylphenol polyoxyethylene ether (OP), nonylphenol polyoxyethylene ether (NP), castor oil polyoxyethylene ether (EL), hydrogenated castor oil polyoxyethylene ether (HEL), fatty alcohol polyoxyethylene ether (MOA), isomeric alcohol polyoxyethylene ether (E13), fatty acid polyoxyethylene ester (A), polyethylene glycol (PEG), or polypropylene glycol (PPG). Using these nonionic surfactants further improves the stability of the aqueous dispersion system.

[0037] In particular, in order to better exert the emulsifier's effect and improve the stability of the aqueous dispersion system, preferably, among at least two nonionic surfactants, castor oil polyoxyethylene ether (EL) series is not present simultaneously with nonylphenol polyoxyethylene ether (NP) series, octylphenol polyoxyethylene ether (OP) series or polyethylene glycol (PEG) series, and fatty acid polyoxyethylene ester (A) series is not present simultaneously with fatty alcohol polyoxyethylene ether (MOA) series; preferably, among at least one anionic surfactant and at least one nonionic surfactant, the anionic surfactant is not a sulfate-type anionic surfactant.

[0038] To better combine the aforementioned reactive hindered amine light stabilizers and reactive ultraviolet absorbers, achieving better dispersion and superior long-lasting protective capabilities in aqueous polymer materials, in a preferred embodiment, R1' is a C6-C10 alkyl group; R1, R2, R3, and R4 are each independently selected from methyl or tert-butyl groups, and R5 is selected from C12-C16 alkyl groups or mixed alkyl groups. Preferably, the reactive ultraviolet absorber is one or more types, and when there are multiple reactive ultraviolet absorbers, R5 is different in different reactive ultraviolet absorbers (in this case, it is equivalent to R5 being a mixed alkyl group). By selecting the above substituents, the corresponding reactive hindered amine light stabilizers and reactive ultraviolet absorbers are more easily and stably dispersed in water under the action of emulsifiers and optional co-emulsifiers.

[0039] Most preferably, the reactive hindered amine light stabilizer is The reactive ultraviolet absorber is

[0040] In a preferred embodiment, the weight ratio of the reactive hindered amine light stabilizer to the reactive ultraviolet absorber in the above-mentioned water-dispersible reactive light stabilizer is 0–95:0–95, preferably 5–40:10–70, and more preferably 20–30:45–55. Controlling the weight ratio within the above range not only results in better compounding effects but also leads to a more significant synergistic effect when applied to waterborne polymer materials.

[0041] The use of sulfonate-type anionic surfactants or phosphate ester-type anionic surfactants has a crucial impact on stabilizing aqueous dispersion systems. To better leverage this effect, sulfonate-type anionic surfactants can, for example, be one or more of alkylbenzene sulfonates (LAS or ABS), α-olefin sulfonates (AOS), alkyl sulfonates (AS or SAS), α-sulfomonocarboxylic acids and their derivatives (MES), fatty acid sulfonyl esters, or fatty acid sulfonyl amides; phosphate ester-type anionic surfactants can be one or more of alkyl phosphate monoesters, alkyl phosphate diesters (AP), alcohol ethers, ester ether phosphate monoesters, and ester ether phosphate diesters.

[0042] For example, the octylphenol polyoxyethylene ether (OP) series surfactants are selected from at least one of OP-4, OP-5, OP-6, OP-7, and OP-10; the nonylphenol polyoxyethylene ether (NP) series surfactants are selected from at least one of NP-4, NP-5, NP-6, NP-7, and NP-10; the castor oil polyoxyethylene ether (EL) series surfactants are selected from at least one of EL-10, EL-12, EL-20, EL-30, EL-40, and EL-60; the hydrogenated castor oil polyoxyethylene ether (HEL) series surfactants are selected from at least one of HEL-20 and HEL-40; and the fatty alcohol polyoxyethylene ether (MOA) series surfactants are selected from MOA-3, MOA-4, and MOA- 5. At least one of MOA-7 and MOA-9; isomeric alcohol polyoxyethylene ether (E13) series surfactants selected from at least one of E1302, E1304, E1306, E1308, E1310, and E1312; ester nonionic surfactants are fatty acid polyoxyethylene ester (A) series surfactants selected from at least one of A105, A110, and A115; polyethylene glycol (PEG) series surfactants selected from at least one of PEG200, PEG300, PEG400, PEG600, PEG800, and PEG1000; polypropylene glycol (PPG) series surfactants selected from at least one of PPG200, PPG400, PPG600, and PPG1000.

[0043] More preferably, when the first component contains a reactive ultraviolet absorber, the emulsifier is a blend of fatty alcohol polyoxyethylene ether series surfactants and isomeric alcohol polyoxyethylene ether series surfactants; preferably, the weight ratio of fatty alcohol polyoxyethylene ether series surfactants to isomeric alcohol polyoxyethylene ether series surfactants is 5-7.5:5-10; more preferably, the emulsifier is a blend of MOA-3 surfactant and E-1310 surfactant; when the first component contains only a reactive hindered amine light stabilizer, the emulsifier is a blend of fatty alcohol polyoxyethylene ether series surfactants and castor oil polyoxyethylene ether series surfactants; preferably, the weight ratio of fatty alcohol polyoxyethylene ether series surfactants to castor oil polyoxyethylene ether series surfactants is 2-4:2-5.2; more preferably, the emulsifier is a blend of MOA-3 surfactant and EL-10 surfactant. In the above-mentioned water-dispersible reactive light stabilizer of the present invention, depending on whether the first component contains a reactive ultraviolet absorber, the above-mentioned specific compound surfactant is preferably used, which is more conducive to forming a tightly packed interfacial film at the interface between the two phases and helps to further maintain the stability of the application system.

[0044] In a preferred embodiment, the amount of emulsifier is 10-30% of the weight of the first component, for example, 12%, 15%, 18%, 20%, 22%, 25%, 28% and intermediate values, more preferably 13-23%. At the above amounts of emulsifier, it is more beneficial to improve the dispersibility and stability of the composite light stabilizer in aqueous polymer materials.

[0045] The aforementioned co-emulsifiers adsorb onto the oil-water interface, further reducing interfacial tension, enhancing the fluidity of the interfacial film, and decreasing the bending energy required for emulsion formation, thus enabling spontaneous emulsion formation. Co-emulsifiers can form interfacial barriers on droplet surfaces, delaying the migration of the composite light stabilizer from small droplets to large droplets. Generally, the co-emulsifier should be soluble in the composite light stabilizer but insoluble in water; the better the water solubility of the co-emulsifier, the worse the delaying effect. There are two mechanisms by which co-emulsifiers achieve co-emulsification: one is through the interaction of dipoles or hydrogen bonds with the composite light stabilizer, dispersing the composite light stabilizer in water and achieving miscibility; the other is through the formation of micelles in water by amphiphilic molecules that have solubilizing ability for the composite light stabilizer, achieving miscibility through the solubilizing effect of the micelles. To more fully utilize these effects, C8 to C18 fatty alcohols are preferred as co-emulsifiers, and dodecyl alcohol is more preferred. When the water-dispersible reactive light stabilizer contains the reactive ultraviolet absorber UV-400, the water-dispersible reactive light stabilizer also contains a co-emulsifier; more preferably, the amount of the co-emulsifier is 3 to 10% of the weight of the first component, for example, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10% and any value between them, more preferably 3.3% to 6.7%.

[0046] According to another aspect of the present invention, an aqueous polymeric material includes a light stabilizer, wherein the light stabilizer is the aforementioned water-dispersible reactive light stabilizer. and Both are liquids at room temperature and are more easily and stably dispersed in water with the help of emulsifiers and optional co-emulsifiers. Therefore, the water-dispersible reactive light stabilizer provided by this invention has good compatibility with water-based polymers, can be stably added to water-based polymers without the need for co-solvents, fully ensuring the environmental friendliness of water-based polymers and eliminating VOC hazards.

[0047] and, The structure retains the low-alkalinity N-OR type matrix, with a reactive hydroxyl group introduced at the other end. The hydroxyl group can chemically crosslink with functional groups in polymer materials, such as isocyanate groups in polyurethane materials, free amine or ether bonds in amino resins, and epoxy groups in epoxy materials. Ultimately, the small-molecule hindered amine light stabilizer is bonded to the matrix polymer chain. In particular, when the aforementioned reactive hindered amine light stabilizer and reactive ultraviolet absorber are used as the main components of the light stabilizer, in addition to their excellent synergistic effect, they exist chemically linked to waterborne polymer materials after application, exhibiting better long-lasting properties and being less prone to volatility, migration, and dissolution. This provides long-term and effective protection for the polymer materials, resulting in superior long-term anti-aging performance of the modified waterborne polymer materials.

[0048] To further enhance the anti-aging properties of waterborne polymer materials, in a preferred embodiment, the effective component of the light stabilizer (i.e., the first component consisting of a reactive hindered amine light stabilizer and / or a reactive ultraviolet absorber) is added to the waterborne polymer material at an amount of 0.1% to 10% based on the solid component. "Based on solid component" represents the proportion of the effective component of the light stabilizer relative to the solid component in the waterborne polymer material.

[0049] The aforementioned waterborne polymer materials can be common types in the polymer field. The specific types of polymer materials mentioned above include, but are not limited to, waterborne acrylic resin materials, waterborne polyurethane materials, waterborne amino resin materials, waterborne epoxy resin materials, waterborne alkyd resin materials, waterborne polyester resin materials, or waterborne phenolic resin materials.

[0050] According to another aspect of the present invention, an aqueous polymer material article includes a light stabilizer, which is the aforementioned water-dispersible reactive light stabilizer, such as, but not limited to, aqueous coatings, aqueous adhesives, aqueous inks, aqueous sealants, aqueous leather, or aqueous shoe sole paste.

[0051] The water-dispersible reactive light stabilizer of this invention can be directly added to aqueous polymer materials or diluted with water before use. Under good stirring conditions, the water-dispersible light stabilizer can be directly added to the aqueous polymer material; however, it is generally used after dilution. Depending on the characteristics of the aqueous polymer material, the water-dispersible light stabilizer is diluted with water at a ratio of 1:1 to 1:100, preferably 1:1 to 1:50, and more preferably 1:3 to 1:10, to effectively avoid foaming problems.

[0052] The present application will be further described in detail below with reference to specific embodiments, which should not be construed as limiting the scope of protection claimed in the present application.

[0100] Performance evaluation test

[0101] (1) Evaluation of water dispersibility and static stability

[0102] Visually inspect the water dispersion effect of the composite light stabilizer emulsion prepared in the above examples after uniform mixing with deionized water at a weight ratio of 1:5, at the initial stage, after standing for 3 days, and after standing for 21 days. A homogeneous emulsion indicates a better water dispersion effect, and vice versa. The aqueous dispersion was allowed to stand at room temperature, and the presence of stratification, sedimentation, turbidity, gelation, or other phenomena was observed. The results are shown in Table 1.

[0103] Table 1

[0104]

[0105]

[0106] (2) Storage stability at high and low temperatures

[0107] To meet the usage requirements of different regions and temperatures worldwide, the composite light stabilizer was stored at 50℃, room temperature (25℃), 2℃, -7℃, and -20℃, with daily records and observations of any phenomena such as stratification, sedimentation, turbidity, or gelation. The results are shown in Table 2.

[0108] Table 2

[0109]

[0110]

[0111]

[0112] (3) Long-term storage stability in water-based coatings

[0113] Solvent-based reactive composite light stabilizers cannot be uniformly dispersed in water (they always remain un-layered, exhibiting oily precipitation). Therefore, when used in water-based polymer materials, especially water-based coatings, they are difficult to disperse evenly, easily causing phenomena such as loss of gloss and mottling. This water-dispersible reactive light stabilizer, on the other hand, can be dispersed well in water-based coatings, and its addition method is more convenient.

[0114] The compound light stabilizer was added at a weight ratio of 2% to a single-component acrylic waterborne industrial paint system (specific components are shown in Table 4). The system was left at room temperature, and the surface was observed every few days for any delamination, precipitation, or other abnormalities. The results are shown in Table 3.

[0118] (4) Long-term weather resistance evaluation

[0119] A. Evaluation of the improvement in weather resistance of water-based dispersible reactive composite light stabilizers in single-component acrylic water-based industrial paints.

[0120] The following single-component acrylic waterborne industrial paint was used as the waterborne polymer material to be evaluated, and its formulation is as follows:

[0121] Table 4

[0122] name Proportion supplier Setaqua 9160 7 Zhanxin Resin Setalux 6100GR-68 19 Zhanxin Resin Setaqua B E270 5 Zhanxin Resin Cymel 373 11 Changxin Resin Titanium dioxide, R960 18 DuPont Barium sulfate 2 Bentone EW 0.5 Hemings Tego 810 0.2 Evonik Tego 450 0.5 Evonik Dipropylene glycol methyl ether 5 Ethylene glycol monobutyl ether 7 Deionized water 26.8

[0123] Based on the above-mentioned waterborne industrial paint system, composite light stabilizers from Examples 1 and 4 were added respectively, at a ratio of 2.1% of the total weight of the waterborne industrial paint. The following test coating samples were obtained by adding different types of light stabilizers.

[0124] The following methods were used to prepare the coating test samples: Steel plates were uniformly used as the substrate. Both sides were uniformly sanded with 800-grit sandpaper. A gray epoxy primer was applied to both sides to a film thickness of 20 micrometers. The primer was allowed to level at room temperature for 10 minutes, then baked in a 120℃ oven for 30 minutes, and finally sanded with 800-grit sandpaper. A water-based gray intermediate coat was applied to a film thickness of 25 micrometers. The primer was allowed to level at room temperature for 10 minutes, then baked in an 80℃ oven for 10 minutes, followed by baking in a 145℃ oven for 30 minutes, and finally sanded with 2000-grit sandpaper. A white water-based industrial topcoat was applied to a film thickness of 35 micrometers. The primer was allowed to level at room temperature for 10 minutes, then baked in a 130℃ oven for 20 minutes. Xenon lamp and QUV tests were started 3 days after surface conditioning.

[0125] The QUV test conditions are as follows: The test plate is placed in the QUV UV aging lamp box (model: Q-Lab QUV / Spray UV fluorescence aging test chamber), and the test standard refers to ASTM G154-06 cylce.

[0126] The xenon lamp test conditions are as follows: the test board is placed in a xenon lamp aging chamber (model: ATLAS Ci4400 xenon lamp aging chamber), and the test standard is SAE J2527 / J1960.

[0127] The test panel was removed at regular intervals to measure the color difference. The colorimeter used was an X-rite MA5 spectrophotometer. Test results are shown below. Figure 1 and Figure 2 ,in Figure 1The QUV aging test color difference curves of the water-based dispersible reactive composite light stabilizers provided in Examples 1 and 4 after application in single-component acrylic waterborne industrial paints are shown (the blank group is the one without anti-aging additives). Figure 2 The color difference change curves of the water-based dispersible reactive composite light stabilizers provided in Examples 1 and 4 after application in a single-component acrylic water-based industrial paint under xenon lamp aging test are shown (the blank group is the one without anti-aging additives).

[0128] B. Evaluation of the weather resistance improvement of waterborne dispersible reactive composite light stabilizers in two-component waterborne acrylic polyurethane topcoats. The following two-component waterborne acrylic polyurethane topcoat was used as the waterborne polymer material to be evaluated, and its formulation is as follows:

[0129] Table 5

[0130] Component A: name Proportion supplier Setaqua 6515 45 Zhanxin Resin SETAL 6306SS-60 4.2 Zhanxin Resin Aerosil 972 0.5 Evonik Titanium dioxide, R960 0.7 DuPont Ultramarine, EP-25 20 New Zealand Barium sulfate 1.2 BYK 011 0.3 BYK Chemical BYK 348 0.4 BYK Chemical Dipropylene glycol methyl ether 3 Dipropylene glycol butyl ether 3 Deionized water 21.7

[0131] Component B: project wt% supplier Bayhydur 2655 9.45 Covestro

[0132] In the above-described waterborne acrylic polyurethane topcoat system, A:B has an NCO:OH ratio of 1.1:1. Composite light stabilizers from Examples 1 and 4 were added, with an addition amount equal to 2.1% of the total weight of the two-component waterborne acrylic polyurethane topcoat. The following test coating samples were obtained by adding different types of light stabilizers.

[0133] The following methods were used to prepare the coating test samples: Steel plates were uniformly used as the substrate. Both sides were uniformly sanded with 800-grit sandpaper. A gray epoxy primer was sprayed onto both sides to a film thickness of 20 micrometers. The primer was allowed to level at room temperature for 10 minutes, then baked in a 120℃ oven for 30 minutes, and finally sanded with 800-grit sandpaper. A solvent-based gray intermediate coat was sprayed to a film thickness of 25 micrometers. The primer was allowed to level at room temperature for 10 minutes, then baked in a 60℃ oven for 30 minutes, and finally sanded with 2000-grit sandpaper. A blue water-based topcoat was sprayed to a film thickness of 50 micrometers. The primer was allowed to level at room temperature for 10 minutes, then baked in an 80℃ oven for 20 minutes. Xenon lamp and QUV tests were started 3 days after surface conditioning.

[0134] The QUV test conditions are as follows: The test plate is placed in the QUV UV aging lamp box (model: Q-Lab QUV / Spray UV fluorescence aging test chamber), and the test standard refers to ASTM G154-06 cylce.

[0135] The xenon lamp test conditions are as follows: the test board is placed in a xenon lamp aging chamber (model: ATLAS Ci4400 xenon lamp aging chamber), and the test standard is SAE J2527 / J1960.

[0136] The test panel was removed at regular intervals to measure the color difference. The colorimeter used was an X-rite MA5 spectrophotometer. Test results are shown below. Figure 3 and Figure 4 ,in Figure 3 The QUV aging test color difference curves of the water-based dispersible reactive composite light stabilizers provided in Examples 1 and 4 after application to two-component waterborne acrylic polyurethane topcoats are shown (the blank group is the one without anti-aging additives). Figure 4 The color difference change curves of the water-based dispersible reactive composite light stabilizers provided in Examples 1 and 4 after application to two-component water-based acrylic polyurethane topcoats are shown in the xenon lamp aging test (the blank group is the one without anti-aging additives).

[0137] The hydroxyl groups in the water-dispersible reactive light stabilizer of the present invention can chemically crosslink with the isocyanate groups in the polyurethane resin. Ultimately, the small-molecule hindered amine light stabilizer is linked to the matrix polymer chain. Therefore, the addition of this composite light stabilizer provides better long-term anti-aging effect for the above system.

[0138] C. Evaluation of the anti-migration properties of water-based dispersible reactive composite light stabilizers in plastic coatings.

[0139] With the trend of replacing steel and wood with plastics, the usage of plastics continues to grow. To achieve both aesthetic and protective effects, a layer of plastic coating can be applied to the surface of plastic substrates. For plastic surfaces used outdoors for extended periods, such as in automobiles, the coating may age due to the effects of light and heat. The addition of hindered amine light stabilizers can slow down this process. However, many plastic substrates themselves have good plasticity, providing some "free space" within the substrate for the migration of small-molecule hindered amine light stabilizers. This test uses PP, a typical plastic material, for testing.

[0140] In the waterborne acrylic polyurethane topcoat system (formulation as in Table 6), the amount of this composite light stabilizer added in the blank group was 2.1% by weight.

[0141] The following test coating samples were obtained by adding different types of light stabilizers.

[0142] Paint test samples were prepared using the following method: PP boards were used as the substrate. A PP-specific primer was applied to a uniform film thickness of 6 micrometers, and allowed to level at room temperature for 10 minutes until surface dry. A solvent-based gray intermediate coat was applied to a uniform film thickness of 25 micrometers, and allowed to level at room temperature for 10 minutes. The samples were then baked in a 60℃ oven for 30 minutes and sanded with 2000-grit sandpaper. A blue water-based topcoat was applied to a film thickness of 50 micrometers, and allowed to level at room temperature for 10 minutes. The samples were then baked in an 80℃ oven for 20 minutes. Xenon lamp and QUV tests were conducted after 3 days of surface conditioning.

[0143] The QUV test conditions are as follows: The test plate is placed in the QUV UV aging lamp box (model: Q-Lab QUV / Spray UV fluorescence aging test chamber), and the test standard refers to ASTM G154-06 cylce.

[0144] The xenon lamp test conditions are as follows: the test board is placed in a xenon lamp aging chamber (model: ATLAS Ci4400 xenon lamp aging chamber), and the test standard is SAE J2527 / J1960.

[0145] The test panel was removed periodically to measure the color difference. The colorimeter used was an X-rite MA5 spectrophotometer. Test results are shown below. Figure 5 and Figure 6 ,in Figure 5 The QUV aging test color difference curves of the water-based dispersible reactive composite light stabilizers provided in Examples 1 and 4 after application in plastic coatings are shown (the blank group is the group without anti-aging additives). Figure 6 The xenon lamp aging test color difference curves of the water-based dispersible reactive composite light stabilizers provided in Examples 1 and 4 after application in plastic coatings are shown (the blank group is the group without anti-aging additives).
