Description

Technical Field

[0001] This invention belongs to the field of fine chemical technology, specifically relating to a water-based ink wetting and leveling agent composition, its preparation method, and its application. Background Technology

[0002] Water-based inks primarily use water as a diluent, resulting in high surface tension, difficulty wetting on non-absorbent substrates, especially low surface energy thin film substrates (PP, PE, PET), and a tendency to develop surface defects such as pinholes, edge shrinkage, orange peel, and floating color during film formation. During the production and use of water-based inks, the circulation of pigments within the system leads to floating color and color blooming issues. Different pigments interact due to their varying fluidities. With these flows and turbulence within the coating film, different pigments, due to differences in particle size and density, severely separate in the eddies, resulting in distinct patterns due to color variations. This is particularly noticeable in light gray water-based inks. Floating color refers to the horizontal, layered separation of pigments in the wet film of water-based inks; color blooming refers to the vertical separation of pigments in the wet film, typically appearing as streaks or honeycomb patterns. Some pigments may concentrate at the hexagonal boundaries of the Bénard vortex, making the hexagonal arrangement clearly visible.

[0003] There are many reasons for floating and mottling in water-based inks, including differences in pigment particle size and density, variations in the hydrophilicity and charge of different substances, and the compatibility between resin and pigment. Smaller pigment particles tend to adsorb much more resin and solvent than larger pigment particles, generally resulting in a lower density for smaller particles and a higher density for larger particles. This increased density of larger pigment particles causes them to sink, while smaller particles float, thus creating the floating phenomenon in printing inks.

[0004] To overcome the problem of poor wetting and leveling of water-based inks on non-absorbent substrates, especially low surface energy film substrates (PP, PE, PET), and to obtain a smooth and clear pattern after the wet film flows and dries, the addition of wetting and leveling agents is absolutely necessary. This is because without these wetting and leveling agents, it would be impossible to obtain a continuous, clear and smooth surface paint film.

[0005] Among the many types of leveling agents, silicone wetting and leveling agents are the most widely used water-based coating and ink wetting and leveling agents because they have the ability to efficiently and quickly balance surface tension, solve paint film defects caused by Bénard vortex, and also have the ability to wet and disperse pigments and fillers as well as certain waterproof properties.

[0006] The related technology discloses the preparation of a polyether polyester modified silicone leveling agent with a number average molecular weight of 100315 by stirring and reacting side-chain hydrogen-containing silicone oil with allyl polyether under methyl isobutyl ketone solvent conditions. However, this method uses methyl isobutyl ketone as a solvent, and the molecular weight of the silicone leveling agent with this structure exceeds 100,000, which greatly limits its migration ability in coating and ink systems. This results in a very weak ability to dynamically balance surface tension, and it does not have the ability to quickly reduce the surface tension of the system during high-speed printing of water-based inks or high-speed spraying of coatings.

[0007] The effectiveness of silicone wetting and leveling agents in water-based ink printing on non-absorbent substrates depends on their ability to reduce the static surface tension of the system and their ability to quickly balance the dynamic surface tension (dynamic surface activity). Specifically, the molecular weight of the polysiloxane, the type, size, position, and number of organic groups, and the linkage method of the organic-modified polysiloxane all affect its effectiveness.

[0008] Therefore, how to develop water-based ink wetting and leveling agents with low surface tension and high dynamic surface activity for use in low-energy surface printing through technological innovation and compatibility technology application, and apply them in water-based inks, water-based coatings, water-based varnishes and other systems, is an urgent problem to be solved.

[0039] (1) This invention uses a ternary synergistic effect of a linear ABC structure acetylenic diol ether single-end modified polysiloxane with rapid balancing of dynamic surface tension in aqueous systems, an isoallyl butyl polyether modified heptamethyltrisiloxane surfactant with high efficiency in reducing static surface tension in aqueous systems, and a biosurfactant with high system compatibility as a highly efficient wetting and leveling agent for water-based inks. An addition of 0.3% can achieve the continuous low surface tension (high dynamic surface activity) of water-based inks when printing rapidly on low-energy surfaces, thus achieving excellent surface wetting and leveling performance on film substrates and obtaining high-quality printing.

[0040] (2) The present invention uses linear ABC structure acetylenic diol ether with appropriate end-capping structure to modify polysiloxane at one end and isoallyl butyl polyether modified heptamethyltrisiloxane surfactant with EO / PO ratio to achieve high surface activity while having low self-foaming stability, which can effectively reduce the foaming problem of water-based inks, while improving the smoothness and water resistance of the coating film.

[0041] (3) The present invention uses isoallyl polyether modified heptamethyltrisiloxane with large steric hindrance as the main material of super wetting agent for water-based ink. Compared with conventional allyl polyether modified heptamethyltrisiloxane, it has higher pH stability and can greatly avoid the failure of wetting and leveling agents in water-based ink systems.

[0120] Performance testing

[0121] The following performance tests were conducted using the water-based ink wetting and leveling agents from Examples 1-3 and Comparative Examples 1-6:

[0122] Add 200g of white acrylic ink and 0.6g of water-based ink wetting and leveling agent to a 500mL beaker, disperse at 300r / min for 5min, adjust the pH to 8.5 with monoethanolamine, stop stirring, and perform the following tests:

[0123] (1) Foaming test: Within 5 minutes, the density of the water-based ink after grinding was tested by weighing.

[0124] (2) Substrate wettability test: A 20μm wire rod was used to scrape and coat the ground water-based ink onto a black PET film substrate. The wet film wettability and the smoothness of the paint film were observed. Based on the overall wetting results of the coating film, the wettability was divided into 10 levels, where level 1 = completely unwettable and level 10 = fully wettable with no paint film defects. At the same time, the dry film gloss and dynamic friction coefficient were tested.

[0125] (3) Leveling test: The leveling instrument was used to determine the 2D flow state of water-based ink on black PET film when the wet film was in a horizontal state. According to the flow results, the leveling was divided into 10 levels, of which level 1 = the worst leveling and level 10 = the best leveling.

[0126] (4) Static surface tension test: Dilute the white water-based ink with deionized water at a mass ratio of 1:1, and test the static surface tension of the diluted water-based ink;

[0127] (5) Dynamic surface tension test: Dilute the white water-based ink with deionized water at a mass ratio of 1:1, and test the dynamic surface tension of the diluted water-based ink at 10ms, 100ms and 400ms.

[0128] (6) Storage stability test: Take 50g of white acrylic water-based ink dispersed with wetting and leveling agent, seal it, put it in a 54℃ oven and keep it at a constant temperature for 14 days, then add 50g of tap water to dilute it, and test the dynamic surface tension of the system and the dynamic surface tension at 10ms, 100ms and 400ms respectively.

[0129] (7) Waterproof test: A 20μm wire rod was used to scrape and coat the ground water-based ink on the black PET film substrate. After the paint film dried naturally, 0.1mL of deionized water was dropped on the surface of the paint film. After 5 minutes, the deionized water was wiped dry. The results were observed whether tap water penetrated into the surface of the coating and whether the coating swelled and fell off.

[0130] (8) Foam stability test: Dilute the wetting and leveling agent with deionized water to prepare a 0.5% aqueous solution of 40g, pour it into a 100mL graduated stoppered cylinder, stopper it, shake it vigorously up and down 20 times, let it stand for 5 minutes, and record the foam height. The higher the foam, the more stable the wetting and leveling agent itself is, which is less conducive to the ease of use of water-based inks.

[0131] Table 1. Comparison of performance test results of wetting and leveling agent samples from various embodiments and comparative examples.

[0132]

[0133] As shown in Table 1, the water-based ink wetting and leveling agents prepared by Examples 1-3 of this invention exhibit excellent wetting and leveling properties, as well as storage stability and pH stability. They effectively improve the dispersion performance of various pigments and fillers, significantly reducing Bénard vortex film defects such as floating color, blooming, and pinholes caused by differences in density and surface properties among pigments and fillers in the water-based ink system. This results in printed materials with high smoothness and a silky feel, effectively enhancing the gloss and water resistance of the printed materials without increasing the foam stability of the system. The overall performance is significantly better than that of Comparative Examples 1-6. Details are as follows:

[0134] The density test results show that the densities of Examples 1-3 range from 0.97 g / mL to 1.01 g / mL, which is comparable to the blank sample. The densities of Comparative Examples 1-6, except for Comparative Example 3, are all less than 0.95 g / mL, demonstrating a certain degree of foam stability. The foam height test data shows that the foam heights of Examples 1-3 are all below 50 mL, slightly lower than the blank sample, while the densities of Comparative Examples 1-6, except for Comparative Example 3, are all greater than 70 mL, indicating significant foam stability.

[0135] The wetting and leveling ability test results show that, compared with the blank sample, the wetting and leveling performance of the water-based inks on PET film substrates was significantly improved after adding 0.3% by weight of Examples 1-3 of this invention. The wetting and leveling ability of Examples 1-3 was significantly better than that of Comparative Examples 1-6. Compared with Example 1, Comparative Example 1 used polyether-modified heptamethyltrisiloxane instead of isoallyl butyl polyether-modified heptamethyltrisiloxane. Although it also achieved certain wetting and leveling properties, its storage stability and pH stability were poor. Polyether-modified heptamethyltrisiloxane was easily hydrolyzed in alkaline systems, causing the correlation energy to disappear rapidly in the system, and it also had foam stability problems. This indicates that the linear ABC structure acetylenic diol ether single-end modified polysiloxane with a suitable end-capping structure and the isoallyl butyl polyether-modified heptamethyltrisiloxane surfactant with an EO / PO ratio used in this invention achieves high surface activity while having low self-foam stability, which can effectively reduce the foaming problem of water-based inks, while improving the smoothness and water resistance of the coating film.

[0136] Comparative Examples 2 and 4-6 did not use ABC-structured acetylacetonate-modified polysiloxane with high dynamic surface activity, so their dynamic surface tension at 400ms reached between 39.1mN / m and 43.1mN / m, which is much higher than the data of Examples 1-3. Consequently, their wetting and leveling properties, water resistance and foam stability also decreased significantly.

[0137] Compared to Example 2, Comparative Example 3, lacking the use of a ternary compound formulation of highly surface-active biosurfactants, exhibited inferior gloss, water resistance, and smoothness compared to Example 2. This indicates that biosurfactants can effectively promote the dispersion and arrangement of water-based ink pigments and fillers in the system, resulting in a highly smooth and dense coating. Furthermore, its 400ms dynamic surface tension was significantly higher than the 27.3mN / m of Example 2, leading to significantly inferior wetting and leveling properties. This demonstrates that biosurfactants, due to their extremely high surface activity and system compatibility, can achieve a synergistic effect with the highly dynamically surface-active ABC-structured acetylenic glycol ether-modified polysiloxane and the isoallyne butyl polyether-modified heptamethyltrisiloxane with super wetting and spreading properties.

[0138] Therefore, this invention employs a ternary synergistic effect of a linear ABC structure acetylenic glycol ether-modified polysiloxane that rapidly balances the dynamic surface tension of the water-based system, an isoallyl butyl polyether-modified heptamethyltrisiloxane surfactant that efficiently reduces the static surface tension of the water-based system, and a biosurfactant with high system compatibility. This synergistic effect serves as a highly efficient wetting and leveling agent for water-based inks, effectively improving the dispersion performance of various pigments and fillers in the water-based ink system. It greatly reduces Bénard vortex film defects such as floating color, blooming, and pinholes caused by differences in density and surface properties among various pigments and fillers in the water-based ink system, resulting in printed materials with high smoothness.

[0139] The present invention has been described in detail above with reference to the embodiments. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
