Abstract
Description
An anti-seepage additive for inkjet printing, its synthesis method and anti-seepage process Technical Field
[0001] This application relates to the field of anti-seepage agents, such as an anti-seepage additive for inkjet printing, its synthesis method, and anti-seepage process. Background Technology
[0002] In the field of printed circuit board manufacturing, after the PCB circuit is manufactured, solder resist ink needs to be printed. Solder resist ink has three main functions: first, it covers the copper circuit and copper surface to prevent short circuits during wave soldering; second, it acts as a protective layer to prevent moisture and other factors from corroding and oxidizing the circuit, thereby affecting its electrical performance; and third, it acts as an insulating medium between copper conductors to improve insulation reliability.
[0003] The relevant solder resist process is mainly as follows: copper surface roughening, ink printing, pre-curing, exposure, development and post-curing. This process has the following shortcomings: (1) The traditional solder resist process adopts a subtractive process, and the ink contains organic solvents, so the production process will generate a large amount of wastewater, waste liquid and waste gas emissions, and the environmental protection problem is prominent. (2) The traditional solder resist ink process is time-consuming, and the process and upstream and downstream cannot achieve line production, making large-scale manufacturing difficult. (3) It is necessary to change the screen or film according to the circuit image, and at the same time, the process requires a lot of equipment and consumes a lot of energy, which is not conducive to reducing production costs.
[0004] To address the above issues, solder resist inkjet printing technology has emerged. Compared to traditional solder resist processes, solder resist inkjet printing technology has a simpler process, consisting only of pretreatment, inkjet printing, and curing. The production process is time-efficient, energy-saving, and generates minimal waste liquid, waste gas, and wastewater, balancing economic and environmental benefits. In recent years, through continuous optimization and improvement, solder resist inkjet printing equipment and inks have gradually become commercialized. However, some challenges remain. The ink has low surface tension, causing it to spontaneously diffuse when sprayed onto the substrate surface, thus affecting printing accuracy and subsequent processes.
[0005] The diffusion of inkjet printing ink on a substrate surface is greatly affected by the substrate's surface energy. Pre-treating the substrate surface to prevent seepage and reduce surface energy is an effective measure. Therefore, developing novel additives that can significantly reduce substrate surface energy is particularly important for the application and promotion of inkjet printing technology. Summary of the Invention
[0006] The following is an overview of the subject matter described in detail herein. This overview is not intended to limit the scope of the claims.
[0007] The purpose of this application is to provide an anti-spray additive for inkjet printing, its synthesis method, and anti-spray process. Substrate surfaces such as metals and resins treated with the anti-spray working solution formulated with the inkjet printing anti-spray additive provided in this application will adsorb a molecular film, reducing the surface energy of the substrate and thus inhibiting the diffusion of inkjet ink on the substrate surface, thereby improving inkjet printing accuracy.
[0008] To achieve this objective, the present application adopts the following technical solution:
[0009] In a first aspect, this application provides an anti-smudging additive for inkjet printing, wherein the raw materials for synthesizing the anti-smudging additive for inkjet printing include compound A and compound B; compound A is an amino-containing polysiloxane; and compound B is a compound containing acryloyloxy group or a compound containing epoxy group.
[0010] This application aims to solve the problem of poor printing accuracy caused by the easy diffusion of ink on the substrate surface during inkjet printing. The diffusion of ink on the substrate surface is greatly affected by the surface energy of the substrate. Pre-treating the substrate surface with an anti-permeability treatment to reduce the surface energy is an effective measure. In this application, compound A is an amino-containing polysiloxane. Polysiloxane chains have low surface tension and high stability. The amino groups in its molecular chain can act as adsorption sites, undergoing physical or chemical adsorption with the surface of substrates such as metals, thus significantly reducing the surface energy of the substrate surface. Compound B has hydrophilic groups in its molecular structure or reacts with compound A to form hydrophilic groups. The inkjet printing anti-permeability additive molecular chain generated after the reaction of chemical A and compound B combines the characteristics of both compounds A and B, possessing the low surface tension of compound A while containing hydrophilic groups, thus improving the poor dispersion of compound A in aqueous solution. Based on this, the substrate surface treated with the inkjet printing anti-permeability additive has a significant inhibitory effect on the diffusion of inkjet ink, exhibiting good anti-permeability and stability.
[0011] Optionally, the amino-containing polysiloxane has the structure shown in Formula I.
[0012] .
[0013] In Formula I, R1 and R3 are each independently selected from any one of -NA2, -BNH2, -BNHA, -A, OA, -OH or -COOH, wherein A is an alkyl group having 1 to 5 carbon atoms (e.g., 2, 3 or 4), B is an alkylene group having 1 to 5 carbon atoms (e.g., 2, 3 or 4), and at least one of R1 and R3 is selected from any one of -NA2, -BNH2 or -BNHA.
[0014] In Equation I, R2 is selected from -(R 1O) x R 3 、-(R 1 O) x (R 2 O) y R 3 -R 1 OCH2CHOHCH2R 4 Any one of the following: an alkyl group having 1 to 5 carbon atoms (e.g., 2, 3, or 4), an alkoxy group having 1 to 5 carbon atoms (e.g., 2, 3, or 4), or a hydroxyl group, wherein R 1 and R 2 Each is independently selected from alkylene groups having 1 to 5 carbon atoms (e.g., 2, 3, or 4), R 3 Selected from alkyl groups having 1 to 5 hydrogen atoms (e.g., 2, 3, or 4 carbon atoms), R 4 Selected from -NHC2H4NH2 or -NHC3H6N(CH3)2, x is an integer from 1 to 20 (e.g., 2, 4, 6, 8, 10, 12, 14, 16 or 18, etc.), and y is an integer from 1 to 10 (e.g., 2, 3, 4, 5, 6, 7, 8 or 9, etc.).
[0015] In Formula I, 10 < m + n ≤ 100, where m and n are integers, such as m + n = 20, m + n = 30, m + n = 40, m + n = 50, m + n = 60, m + n = 70, m + n = 80 or m + n = 90, and n is an integer from 0 to 50 (e.g., 5, 10, 15, 20, 25, 30, 35, 40 or 45, etc.).
[0016] In this application, the surface energy of compound A is affected by the degree of polymerization. If the degree of polymerization is too low, it will not be enough to significantly reduce the surface energy of the substrate after adsorption on the substrate surface. Therefore, the degree of polymerization needs to be relatively high. However, if the degree of polymerization is too high, it will result in poor dispersion ability in aqueous solution. It is easy for the microdroplet particles formed after dispersion to have a large diameter or to re-layer after dispersion. This will result in a large number of dot-like residues or deterioration of performance on the surface of the substrate after treatment with the anti-seepage working solution prepared with anti-seepage additive for inkjet printing.
[0017] Optionally, in Formula I, R1 and R3 are each independently selected from any one of -N(CH3)2, -C2H4NH2, -C3H6NH2, -C4H8NHC2H5 or -CH3.

[0045] , .
[0046] In this application, compound B can be a compound with a hydrophilic structure in its molecular structure. For example, compound B can be a compound with the structure shown in formula II-1 or formula II-2, wherein each of R4 is independently selected from -(C2H4O). q R 6 -(CH2)2N + (CH3)2R 7 Cl - -(CH2)2PO4 - (CH2)2N + (CH3)3、-(CH2)2N + (CH3)2(CH2)3SO3 - Compound B can be a compound with the structure shown in Formula III-3, which contains -CH2N + (R7)3Cl - The reason for this is that reactant A is an amino-containing polysiloxane, whose main chain has poor dispersibility in water. By reacting with compound B, which has a hydrophilic structure, its dispersibility in aqueous solution can be improved, thus enhancing the performance stability of the inkjet printing anti-staining additive. In addition, when the hydrophilic group in reactant B is a quaternary ammonium group, the quaternary ammonium group has a better adsorption effect on substrates such as metals. Therefore, after reactant B reacts with reactant A, the quaternary ammonium group is grafted onto the polysiloxane chain, which can increase the density of active adsorption groups on the inkjet printing anti-staining additive, enhance the adsorption capacity of the inkjet printing anti-staining additive on the surface of substrates such as metals (e.g., copper), and thus improve the anti-staining effect of the metal substrate on the inkjet printing ink.

[0063] Thirdly, this application provides a seepage prevention process, which includes the following steps:

[0069] Optionally, the concentration of the inkjet printing anti-seepage additive in the anti-seepage agent described in process (a) is 2.5~50 g / L, such as 5 g / L, 10 g / L, 15 g / L, 20 g / L, 25 g / L, 30 g / L, 35 g / L, 40 g / L or 45 g / L.
[0070] Optionally, the concentration of the organic solvent in the anti-seepage agent described in process (a) is 100~500 g / L, such as 150 g / L, 200 g / L, 250 g / L, 300 g / L, 350 g / L, 400 g / L or 450 g / L.
[0071] For example, the organic solvent includes any one or a combination of at least two of the following organic solvents: diethylene glycol, diethylene glycol monobutyl ether, diethylene glycol monohexyl ether, diethylene glycol monophenyl ether, ethylene glycol monoisopropyl ether, or tripropylene glycol.
[0072] Optionally, the acid includes organic acids and / or inorganic acids.
[0073] Optionally, the acid includes any one or a combination of at least two of formic acid, acetic acid, phosphoric acid, boric acid, hydrochloric acid, or sulfuric acid.
[0074] Optionally, the pH of the anti-seepage agent is 5.0 to 7.0, such as 5.2, 5.4, 5.6, 5.8, 6.0, 6.2, 6.4, 6.6 or 6.8.
[0075] Optionally, process (b) includes the following steps: diluting the anti-seepage agent obtained in process (a) with water to obtain an anti-seepage working solution.
[0076] Optionally, the concentration of the anti-seepage agent in the anti-seepage working solution is 20~60 mL / L, such as 25 mL / L, 30 mL / L, 35 mL / L, 40 mL / L, 45 mL / L, 50 mL / L or 55 mL / L.
[0077] Optionally, the substrate is an ultra-roughened plate.
[0078] In this application, the term "roughened board" refers to a copper-clad laminate that has undergone an ultra-roughening treatment. The ultra-roughening treatment can be carried out using methods known in the art, which will not be elaborated here.
[0079] Optionally, the spraying process described in process (c) is a continuous spraying process.
[0080] In this application, the process parameters of the spraying treatment in process (c) also have a certain impact on the seepage prevention effect.
[0081] Optionally, the temperature of the spray treatment is 20~30℃, such as 21℃, 22℃, 23℃, 24℃, 25℃, 26℃, 27℃, 28℃ or 29℃.
[0082] In this application, the temperature of the continuous spraying treatment can be selected as 20~30℃. If the temperature is too low, the inkjet printing anti-seepage additive components in the anti-seepage working fluid are prone to precipitation, resulting in a poor anti-seepage effect. If the temperature is too high, the organic solvent in the anti-seepage working fluid evaporates faster, which is not conducive to the stable operation of the anti-seepage working fluid.
[0083] Optionally, the spray pressure of the continuous spray treatment is 1~2.5 kg / cm². 2 For example, 1.2 kg / cm 2 1.4kg / cm 2 1.6 kg / cm 2 1.8 kg / cm 2 2.0 kg / cm 2 2.2 kg / cm 2 Or 2.4 kg / cm 2 The value can be selected as 1~2 kg / cm³. 2 .
[0084] In this application, the spray pressure of the continuous spray treatment can be selected as 1~2.5 kg / cm². 2 If the pressure is too low, the contact between the anti-seepage working fluid and the substrate surface will be insufficient, resulting in uneven adsorption of the anti-seepage additive for inkjet printing on the substrate surface, which may lead to poor local anti-seepage effect on the substrate surface; if the pressure is too high, the load on the circulation pump will increase and shorten the life of the circulation pump.
[0085] Optionally, the continuous spraying treatment time is 20~80 s, such as 25 s, 30 s, 35 s, 40 s, 45 s, 50 s, 55 s, 60 s, 65 s, 70 s or 75 s, etc.
[0086] In this application, the continuous spraying treatment time can be selected as 20~80 s. If the time is too short, the inkjet printing anti-seepage additive will not be fully adsorbed on the substrate surface, resulting in a poor anti-seepage effect; if the spraying treatment time is too long, it will reduce production efficiency.
[0087] Compared with related technologies, this application has the following advantages:
[0088] The anti-seepage working fluid made from the anti-seepage additive for inkjet printing described in this application can reduce the surface energy of the substrate after treating the substrate surface, thereby effectively inhibiting the spontaneous diffusion of inkjet ink on the substrate surface, resulting in good anti-seepage effect and helping to improve inkjet printing accuracy.

[0190] (2) Anti-seepage agent residue test: perform electroplating copper treatment on the ultra-roughened board treated with the anti-seepage working solution, clean and blow dry after electroplating, then perform 20 times of reflow soldering treatment, and observe the delamination between the copper plating layer and the ultra-roughened board treated with the anti-seepage working solution. If delamination or board explosion occurs, it is regarded as unqualified, otherwise it is regarded as qualified.
[0191] (3) Adhesion test: spray the same inkjet ink on the surface of the ultra-roughened board by an inkjet printer (spraying thickness is 25μm), then perform pre-curing (80°C, 1h), light curing (500mJ / cm 2 ) and heat curing (150°C, 1h) in sequence to form ink drops. Cut two incisions with an interval of 1cm on the surface of the cured ink drops with a scalpel, then soak in 6N hydrochloric acid for 10min, after washing and drying, use 3M 600 series tape to attach to the ink surface for peeling treatment, and evaluate the adhesion strength of the solder resist ink on the copper clad laminate. If the ink drop does not fall off after 3 consecutive pulls, it is regarded as qualified, otherwise it is regarded as unqualified.

After the inkjet ink is completely cured, perform a thermal shock test thereon, specifically, perform tin dipping treatment thereon, the tin dipping temperature is 288°C, and the number of times is 6 times. If the ink drop formed by curing the inkjet ink does not fall off in all 6 tests, it is qualified, otherwise it is regarded as unqualified.
[0193] The test results are shown in Table 1 below.
[0194]
[0195] In Table 1, “—” indicates that the test was not performed.
[0196] The anti-seepage agents provided in Examples 1-13 and Comparative Examples 1-2 were tested as follows.
[0197] (1) Storage stability: Store the anti-seepage agent at -5℃ and 40℃ for 10 days respectively, and observe the changes in the appearance of the anti-seepage agent. If there are any adverse phenomena such as oil floating, layering, or turbidity, it is considered unqualified, otherwise it is qualified.
[0198] (2) Aging resistance test: The anti-seepage agent and deionized water were mixed to prepare the anti-seepage working solution. The concentration of the anti-seepage agent in the anti-seepage working solution was 40 mL / L. 5 L of the above anti-seepage working solution was placed in a spraying machine, and then the temperature was heated to 25℃. After heating, the ultra-roughened plate was sprayed. The spraying pressure was 1 kg / cm². 2 The spraying treatment time is 40 seconds; after the anti-seepage working fluid is consumed, the anti-seepage agent is manually added to the spray tank, with each addition being 5 mL / (m²). 2 (·L), while the pH of the seepage prevention working solution is monitored online using an online pH meter, and controlled within the range of 5-7. Each liter of seepage prevention working solution can continuously treat 5m³ 2 After the plate is roughened, assess whether the anti-smudging effect on the inkjet printing can be maintained when the plate is further roughened. If it can be maintained, it is qualified; if it cannot be maintained, it is unqualified.
[0199] The test results are shown in Table 2 below.
[0200]
[0201] In Table 2, “—” indicates that the test was not performed.
[0202] As can be seen from Tables 1 and 2, the anti-seepage additives for inkjet printing prepared in Examples 1 to 13 have good storage stability and good aging resistance. The ultra-roughened plate treated with the prepared anti-seepage working solution has good stability. The anti-seepage treatment does not affect the bonding force between the inkjet ink and the copper surface of the ultra-roughened plate, and has no negative impact on thermal reliability.
[0203] As shown in Figure 1, in Example 1, compound A (denoted as A1) at a wavenumber of 788 cm⁻¹ -1 (Si-CH3, Si-CH2-), 1021~1088 cm -1 (Si-O) and 1257cm -1Four groups of vibrational absorption peaks characteristic of the polysiloxane backbone appeared at (Si-CH3). Due to the relatively large molecular weight and low amino content of A1, no -NH2 absorption peak appeared in the infrared spectrum. Compound B (denoted as B1) in Example 1 is acryloyloxyethyltrimethylammonium chloride, which has an absorption peak at a wavenumber of 951 cm⁻¹. -1 Location, 1188cm -1 ~1268cm -1 Location, 1481cm -1 Location, 1636cm -1 Location, 1726cm -1 Characteristic absorption peaks are observed at these locations, corresponding to the vibrational absorptions of CN, CO, CH, C=C, and C=O bonds, respectively. A1 and B1 can undergo a Michael addition reaction via an amino group and a double bond; after the reaction, the double bond disappears, and the primary amine is converted to a secondary amine. The product of A1 and B1 (denoted as C1) exhibits a polysiloxane chain absorption peak (788 cm⁻¹) attributable to A1 in its infrared spectrum. -1 1009cm -1 1088cm -1 1257cm -1 ) and the C=O absorption peak of B1 (1739 cm⁻¹) -1 However, C=C(1636cm) belongs to B1. -1 The disappearance of the absorption peak indicates that A1 and B1 have successfully reacted to form a new substance C1, namely the inkjet printing anti-bleeding additive prepared in Example 1.
[0204] As shown in Figure 2, in Example 2, compound A (denoted as A2) at a wavenumber of 788 cm⁻¹ -1 (Si-CH3, Si-CH2-), 1012~1079 cm -1 (Si-O), 1256cm -1 Four groups of vibrational absorptions characteristic of the polysiloxane backbone appeared at (Si-CH3). Because A2 has a larger molecular weight and lower amino content, no -NH2 absorption peak or characteristic absorption peak appeared in the infrared spectrum. Compound B (denoted as B2) in Example 2 is ethylene glycol diglycidyl ether, and its absorption at a wavenumber of 755 cm⁻¹... -1 851cm -1 910cm -1 And 1091cm -1 A strong absorption peak is observed at this location, corresponding to the characteristic absorption peaks of the epoxy group and COC bond. A2 and B2 can undergo an addition reaction between the amino group and the epoxy group, after which the epoxy group undergoes ring-opening to convert to an alcohol, and the primary amine to a secondary amine. The product of A2 and B2 (denoted as C2) exhibits a polysiloxane chain absorption peak (786 cm⁻¹) attributable to A2 in its infrared spectrum. -1 1009cm -1 1082cm-1 1260cm -1 The disappearance of the characteristic absorption peak of B2 indicates that A2 and B2 have successfully reacted to form a new substance C2, namely the inkjet printing anti-bleeding additive prepared in Example 2.
[0205] As can be seen from Application Examples 1, 2, 3, 6 and Comparative Application Example 1, when the prepared anti-seepage agent working solution contains anti-seepage additive components for inkjet printing, the inkjet ink does not diffuse on the surface of the treated ultra-roughened plate, as shown in Figures 3-6. If the prepared anti-seepage agent working solution does not contain anti-seepage additive components for inkjet printing, the inkjet ink diffuses on the surface of the treated ultra-roughened plate, as shown in Figure 11. This shows that the anti-seepage additive components have a significant impact on the anti-seepage effect, and further demonstrates that the anti-seepage additive for inkjet printing provided in this application has an excellent anti-seepage effect.
[0206] As can be seen from Application Examples 1 and 9, when the pH of the anti-seepage agent is between 5.0 and 7.0, the inkjet ink does not diffuse on the surface of the ultra-roughened plate after treatment with the prepared anti-seepage working solution, as shown in Figures 3 and 7. It can be seen that within this pH range, the anti-seepage additive for inkjet printing provided in this application has chemical stability, and thus the anti-seepage performance is stable.
[0207] As can be seen from Application Examples 1 and 14, the concentration of the anti-seepage agent in the anti-seepage working solution is in the range of 20~60 mL / L, the spraying temperature is in the range of 20~30℃, and the spraying pressure is in the range of 1~2 kg / cm². 2 Within the range of 20-60 seconds, the inkjet printing ink did not diffuse on the surface of the ultra-roughened plate after treatment with the anti-seepage working solution, as shown in Figures 3 and 10. This indicates that the anti-seepage effect of the anti-seepage agent working solution is good under this anti-seepage process.
[0208] Compared with Application Example 1, if the polymerization degree of compound A is too small, the prepared anti-seepage working solution is used for anti-seepage treatment of ultra-roughened plate (Application Example 12). The anti-seepage effect is shown in Figure 8. The inkjet ink diffuses to a certain extent, and the anti-seepage effect decreases.
[0209] Compared with Application Example 1, if the polymerization of compound A is too large, the prepared anti-seepage working solution is used for anti-seepage treatment of the ultra-roughened plate (Application Example 13). The anti-seepage effect is shown in Figure 9. The inkjet ink diffuses slightly, and the anti-seepage effect decreases. In addition, there are substances remaining on the surface of the treated ultra-roughened plate, which leads to poor adhesion between the inkjet ink and the copper surface. The cured inkjet ink falls off after thermal shock.
[0210] Compared to Application Example 1, if the inkjet printing anti-staining additive is hydroxyl-terminated polydimethylsiloxane (Comparative Example 2), which has no amino groups in its molecular structure, the anti-staining working solution prepared in this way is used for anti-staining treatment of ultra-roughened plates (Comparative Application Example 2). The anti-staining effect is shown in Figure 12. The inkjet ink diffuses significantly on the treated copper surface, and the anti-staining effect is significantly worse than that of Application Example 1, but comparable to that of Comparative Application Example 1. This indicates that the amino structure has a significant impact on the anti-staining effect of the inkjet printing anti-staining additive. This is because when the anti-staining additive has no amino groups in its molecular structure, it is difficult to adsorb onto the copper surface and therefore cannot play a role.
[0211] As shown in Figures 12 and 13, the anti-seepage agent provided in Example 1 underwent aging resistance testing and continuous anti-seepage treatment for 5m. 2 / L and 10m 2 When using / L ultra-roughened boards, they all maintain good seepage prevention and have good aging resistance.
[0212] In summary, the anti-sperm additive for inkjet printing described in this application can effectively inhibit the spontaneous diffusion of inkjet ink, has good anti-sperm effect, good storage stability, good binding effect with inkjet ink, and maintains stable performance after aging.
