Description

Technical Field

[0001] This invention relates to the field of plastic removal technology, specifically to a nano-plastic remover and its preparation method. Background Technology

[0002] Currently, there are two main types of plastic removal coatings on the market: water-based plastic remover and transfer coating (transfer film) processes. Water-based plastic remover is widely recognized and used by most manufacturers due to its environmental friendliness, but its performance in terms of wear resistance, folding resistance, explosion-proof color, and scratch resistance still needs improvement, and it can currently only be used as a downgrade according to customer requirements. The transfer coating process involves transferring the UV coating applied to PET or PP film onto the printed sheet using adhesive to achieve wear resistance, folding resistance, explosion-proof color, and scratch resistance. This process is better than water-based plastic remover in terms of performance, but because it still uses plastic film in the production process, it does not achieve the purpose of plastic removal. Summary of the Invention

[0003] In order to solve the problems existing in the prior art, the present invention aims to provide a nano-plastic remover and its preparation method.

[0004] On one hand, the present invention discloses a nano-plasticizer, comprising the following components: 8-12 wt% photoinitiator, 48-52 wt% modified polyurethane acrylate, 8-10 wt% modified polyester acrylate, 25-28 wt% active monomer, 0.4-0.6 wt% leveling agent, 0.8-1.0 wt% surface energy enhancer, 1.6-2.0 wt% oxygen polymerization inhibitor, and 0.4-0.6 wt% defoamer.

[0005] Preferably, in the photoinitiator: 1-hydroxycyclohexylphenyl ketone accounts for 35-45%, ethyl 2,4,6-trimethylbenzoylphenylphosphonate (TPO-L) accounts for 20-30%, and methyl benzoylformate (MBF) accounts for 30-40%. The combination of 1-hydroxycyclohexylphenyl ketone, TPO-L, and MBF, wherein 1-hydroxycyclohexylphenyl ketone dominates the surface free radical polymerization, TPO-L is used as an aid for deep curing, penetrating the coating to achieve deep curing, and has better environmental performance than TPO, while MBF improves conversion efficiency, increasing the double bond conversion rate to >95%. This photoinitiator combination ensures that both the surface and deep layers of the coating are fully cured during UV curing, improving the overall curing effect and performance of the coating. The 1-hydroxycyclohexylphenyl ketone, TPO-L, and MBF in the photoinitiator generate active free radicals after absorbing ultraviolet light. These free radicals can initiate the polymerization reaction of the active monomer HDDA and silicone-modified polyether acrylate. The polymerization of reactive monomers transforms the coating from a liquid to a solid state. Simultaneously, the rapid polymerization of reactive monomers increases the curing speed of the coating, allowing the photoinitiator to fully exert its effect. Furthermore, the free radical polymerization reaction initiated by the photoinitiator can open the double bonds in the modified polyurethane acrylate, thereby crosslinking the modified polyurethane acrylate into the network structure of the coating. This crosslinking enhances the coating's flexural strength and scratch resistance. At the same time, the flexibility of the modified polyurethane acrylate also improves the brittleness of the coating after photoinitiator curing, resulting in better flexibility and flexural strength.

[0006] Preferably, the modified polyurethane acrylate is formed by grafting long-chain polyether-modified polysiloxane (such as hydroxyl polydimethylsiloxane) onto the main chain of the polyurethane acrylate. The flexibility of the siloxane provides a skin-like feel, while the polyether segment enhances compatibility with the acrylate. The modified polyurethane acrylate is a mixture of 2-functional and 6-functional resins, wherein the mass ratio of the 2-functional to 6-functional resins is 3:1, ensuring the nano-plasticizer's functions such as fold resistance, explosion-proof color, scratch resistance, and self-healing. 2-functional and 6-functional groups refer to molecules with 2 or 6 reactive polyurethane acrylate groups. Through a molecular-level "rigid-flexible complementary" design, the long-standing performance contradiction in the coating field—"high hardness inevitably leads to brittleness, and high flexibility inevitably leads to softness"—is resolved. Specifically:

[0007] A 6-functional resin serves as a rigid crosslinking node (size 2-5 nm) to form a high-density crosslinking framework (crosslinking density 3.0 mol / m³). 3 The abrasion resistance can reach >5000 cycles. The 2-functional resin, as a flexible connecting chain (containing siloxane segments), provides entropy elastic buffer (elongation at break >80%), achieving >50 folding resistance and 92% self-healing efficiency.

[0008] By combining long-chain polyethers with polysiloxanes through chemical reactions or physical blending, the advantages of both can be combined. This modified polysiloxane not only retains the flexibility and heat resistance of polysiloxanes, but also enhances its compatibility with other materials (especially acrylate materials) due to the introduction of long-chain polyethers. During the chemical synthesis process, the modified polysiloxane is attached to the resin backbone formed by polyurethane acrylate (PUA) through a chemical reaction. This grafting method allows the modified polysiloxane to exist more stably in the resin system, fully utilizing its advantages such as flexibility and compatibility, while also helping to improve the overall performance of the resin system, such as flexibility, folding resistance, and scratch resistance.

[0009] Preferably, the modified polyester acrylate includes perfluoroalkyl-modified polyester acrylate (such as perfluorodecyl-modified polyester acrylate). Perfluoroalkyl-modified polyester acrylate (hereinafter referred to as perfluoroalkyl acrylate) is a polyester modified by end-capping or side-chain modification of perfluoroalkyl chains. It possesses properties such as low surface energy, excellent heat resistance, chemical corrosion resistance, and hydrophobicity and oleophobicity, which can significantly improve coating performance. Perfluoroalkyl chains have strong polarity and can be strictly oriented and directionally arranged on the material surface, thereby forming a low surface energy surface region, enhancing the hydrophobicity and oleophobicity of the material, and significantly improving stain resistance to achieve an anti-fingerprint function.

[0010] Modified polyurethane acrylate provides the coating with flexibility and scratch resistance, while the perfluoroalkyl acrylate in the modified polyester acrylate imparts hydrophobicity and oleophobicity, thus achieving fingerprint resistance. The combination of these two components gives the coating both excellent mechanical properties and unique surface properties, meeting the comprehensive performance requirements of printed materials that need to be abrasion-resistant, fold-resistant, scratch-resistant, and fingerprint-resistant. The polyether segment in the modified polyurethane acrylate enhances its ester compatibility with the modified polyester acrylate, allowing both to be uniformly dispersed in the coating and forming a stable network structure. This good compatibility avoids phase separation during use, ensuring the stability and durability of the coating performance.

[0011] Preferably, the active monomer comprises 1,6-hexanediol diacrylate (HDDA) and silicone-modified polyether acrylate, wherein the mass ratio of 1,6-hexanediol diacrylate to silicone-modified polyether acrylate is 1:3. The active monomer provides the nano-plasticizer with properties such as fold resistance, explosion-proof color, and scratch resistance. The bifunctional monomer of HDDA acts as a crosslinking anchor, increasing the crosslinking density, reducing the system viscosity (contribution value 15 cPs), and preventing the gelation of high-functionality resins. The polyether segments of the silicone-modified polyether acrylate (molecular weight 2000) enhance chain mobility, ensuring low-temperature flexibility (no breakage at -20℃), a surface tension of 24 mN / m, and assisting in leveling (roughness Ra < 0.1 μm). In addition, the active monomers HDDA and silicone-modified polyether acrylate have high reactivity and can react rapidly with the double bonds in the modified polyurethane acrylate to form a tight crosslinked network structure. This cross-linked network structure not only improves the coating's hardness and wear resistance but also enhances its resistance to chemical corrosion. The addition of silicone-modified polyether acrylate further improves the individual properties of the active monomers, giving the coating high hardness while also providing a degree of flexibility and self-healing ability. When the coating is subjected to external scratches, the flexible segments within it can mitigate the impact to some extent, reducing scratches. Furthermore, during subsequent use, the coating can self-repair to a certain degree through its own flexibility.

[0012] In this embodiment, the perfluoroalkyl acrylate has extremely low surface energy, allowing the coating to form numerous tiny protrusions and depressions. When illuminated, there is almost no specular reflection at 60° because the light undergoes diffuse reflection on the rough surface, thus achieving a matte effect. Furthermore, the appropriate ratio of HDDA and silicone-modified polyether acrylate allows them to react and form a dense coating with fine roughness, increasing light scattering and reducing specular reflection, which helps achieve the required matte finish.

[0013] Preferably, the leveling agent comprises a polyether acrylate with a molecular weight of 2000-5000 Da, which has excellent substrate wetting ability, anti-cratering ability, does not affect adhesion, and can effectively reduce the surface tension of the system to 23 mN / m, eliminating cratering and achieving a matte finish retention rate of >99%. The leveling agent reduces the surface tension of the coating, improves the leveling properties of the coating on the substrate, and allows the coating to be uniformly applied to the surface of the printed material. The flexibility of the modified polyurethane acrylate complements the effect of the leveling agent, allowing the coating to better adapt to the surface of the substrate during the drying process, forming a smooth and even coating surface and improving the appearance quality of the coating.

[0014] Preferably, the surface energy enhancing agent includes one of acrylate copolymers and quaternary ammonium salt modified acrylates. These additives are all silicone- and fluorine-free surface additives, which, while increasing the surface energy of the cured coating, do not pollute the environment and are safer, achieving recoatability of the nano-plastic oil removal process, complying with environmental regulations, and promoting sustainable development. Furthermore, the surface energy enhancing agent can increase the surface energy of the cured coating, giving it better adhesion and recoatability. The modified polyester acrylate imparts hydrophobic and oleophobic properties to the coating; under the action of the surface energy enhancing agent, it can ensure the anti-fingerprint performance of the coating while making the coating surface easier to bond with other materials, providing convenience for subsequent processing and use.

[0015] Preferably, the oxygen inhibition inhibitor comprises one of pentaerythritol tetra(3-mercaptopropionate), pentaerythritol tetramercaptopropionate, and trimethylolpropane tri(3-mercaptopropionate). This inhibitor can be a thiol compound, which functions to reduce the influence of oxygen on UV surface curing. The oxygen inhibition inhibitor can reduce the influence of oxygen on the photoinitiator curing reaction, ensuring the curing effect of the photoinitiator on the coating surface. Under the protection of the oxygen inhibition inhibitor, the photoinitiator can more effectively initiate the polymerization reaction of the active monomer and modified polyurethane acrylate, improving the curing depth and performance uniformity of the coating.

[0016] Preferably, the defoamer comprises one of a hydrocarbon-chain modified acrylic polymer, a fatty alcohol and a polyoxyethylene ether copolymer. The defoamer can be a polymer-type defoamer, free of silicone, possessing rapid and efficient defoaming capabilities, and significantly shortening the defoaming process in high-viscosity systems.

[0017] On the other hand, this invention discloses a method for preparing nano-plastic remover, comprising the following steps:

[0018] Mix the active monomers according to the specified ratio and stir until homogeneous to form Agent A, for later use;

[0019] Modified polyurethane acrylate and modified polyester acrylate are mixed with half of agent A and stirred evenly to form agent B.

[0020] Mix the photoinitiator according to the ratio and stir evenly. Then add the other half of agent A and stir for 15-20 minutes at 45-50℃ and 400-600r / min until the photoinitiator is completely dissolved to form agent C. The photoinitiator first dissolves in part of the monomer (agent A) at 45-50℃ to avoid high-temperature decomposition of TPO-L. The solubility rate is >99%.

[0021] Mix agent B and agent C, and stir evenly at 1000-1500 r / min to form agent D;

[0022] Add leveling agent, surface energy enhancer, oxygen polymerization inhibitor and defoamer to agent D while stirring. After the addition is complete, stir at 1000-1500 r / min for 30-40 min to obtain crude reagent.

[0023] The crude reagent is filtered, barrelled, and packaged to obtain nano-plastic remover.

[0024] The nano-plastic remover of this invention has the advantage of achieving excellent comprehensive performance through the rational combination of photoinitiators, modified polyurethane acrylates, modified polyester acrylates, active monomers, and additives. The photoinitiator combination ensures full curing of both the surface and deep layers of the coating; the modified polyurethane acrylates impart flexibility, folding resistance, scratch resistance, and self-healing ability to the coating; the modified polyester acrylates provide hydrophobic and oleophobic properties, achieving an anti-fingerprint effect; the active monomers increase crosslinking density and hardness, enhancing abrasion resistance and chemical corrosion resistance; and the additives optimize the coating's leveling properties, surface energy, defoaming, and degassing performance. Compared with water-based plastic removers, the product of this invention exhibits superior performance in abrasion resistance, folding resistance, scratch resistance, matte finish, and transparency, while achieving zero VOC emissions, meeting environmental protection requirements, and providing comprehensive protection and excellent performance for printed materials. The nano-plastic remover of this invention is a 100% solids-content environmentally friendly coating that can form a nano-level matte coating on printed sheets through UV processing, while simultaneously providing excellent abrasion resistance, folding resistance, explosion-proof color, scratch resistance, and tactile properties. The nano-plastic remover of this invention can simultaneously meet customers' performance requirements for high wear resistance, high folding resistance, good scratch resistance, low matteness (down to less than 1° at a 60-degree angle), and excellent coating transparency on different types of paper and inks. In addition, it can also achieve 0VOC emissions and excellent environmental performance.

[0025] This invention discloses a simple method for preparing nano-plastic remover. By mixing the components in stages and precisely controlling the temperature, proportions, and stirring speed, the stability of the nano-plastic remover's performance is ensured. First, monomers are prepared as agent A in a specific ratio. Then, modified polyurethane acrylates and other components are prepared as agent B. Next, a photoinitiator is added to agent A and heated and stirred until dissolved. Then, agent B is added and stirred until homogeneous. Finally, additives are added, stirred until homogeneous, filtered, and packaged. This method ensures that all components react fully and disperse evenly, guaranteeing product quality and performance. The entire process is easily scalable for mass production, providing the coatings industry with an efficient and stable solution for preparing high-performance nano-plastic remover, and strongly promoting the development of environmentally friendly high-performance coatings.

[0083] Comparative Example 1

[0084] Uses traditional BOPP plastic film;

[0085] Comparative Example 2

[0086] Lambo XS360 water-based plasticizer remover, manufactured by Dongguan Lanbo Chemical Technology Co., Ltd., was purchased from the market.

[0087] The nano-plastic remover produced in Examples 1-4, the plastic film in Comparative Example 1, and the water-based plastic remover in Comparative Example 2 were compared and tested under the same conditions. The results are shown in the table below.

[0088]

[0089] In summary, in terms of environmental performance, the VOC emissions in all four embodiments of the present invention are zero, while Comparative Example 1 and Comparative Example 2 both have VOC emissions, which cause significant environmental pollution. The nano-plasticizer of the present invention has excellent environmental performance.

[0090] Functionally, the nano-plastic remover of this invention exhibits abrasion resistance exceeding 90% of that of plastic films, thus significantly improving scratch resistance. The nano-plastic removers of Examples 1-4 can withstand at least 50 bends without breaking, while Comparative Example 2 only withstands 8. This is attributed to the synergistic effect of modified polyurethane acrylate and photoinitiators, which give the coating excellent flexibility and folding resistance, allowing it to withstand repeated bending during the use of printed materials. The nano-plastic remover of this invention achieves extremely low matte finish (60° gloss less than 1°), while the two comparative examples have a matte finish of at least 8°. This is mainly due to the special process and composition design, enabling it to meet the market demand for high-end matte products, providing a skin-like feel while being non-reflective and offering a superior visual effect.

[0091] In terms of process adaptability, the recoatability solves the pain point of multi-layer printing. In Comparative Example 1, the BOPP film coating and the water-based plastic remover coating in Comparative Example 2 could not be coated again and were easily peeled off in layers. However, the nano plastic remover in Examples 1-4 of this invention can be repeatedly scraped and coated.

[0092] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this invention.
