Description

Technical Field

[0001] The present application belongs to the field of coating technology, and specifically relates to a fluorosilicone polyether additive, an additive composition, a coating composition, a coating, a coating, and a product having a coating. Background Art

[0002] Currently, there are various types of coatings (including water-based coatings) on the market suitable for various application environments. A smooth, crater-free surface is crucial for many coating applications. However, existing coatings can develop craters on the coating film surface during the spraying process due to various factors, resulting in poor coating appearance. Summary of the Invention

[0003] In order to solve the technical problem that the existing coatings have poor appearance due to the generation of shrinkage cavities, the present application provides a fluorosilicone polyether additive, an additive composition, a coating composition, a coating, a coating and a product having the coating.

[0004] In a first aspect, the present invention provides a fluorosilicone polyether additive comprising an active substance, wherein the chemical composition of the active substance has the chemical structure shown in Formula I:

[0005]

[0006] In Formula I,

[0007] R1, R2, R3 and R4 are the same or different, and are independently selected from the following: alkyl, oxygen-containing group, halogen.

[0008] It can be seen from the above technical solution that the fluorosilicone polyether additive provided in the embodiment of the present application, on the one hand, the main chain structure of the chemical component of the active substance in the fluorosilicone polyether additive is a polysiloxane chain containing a "-F-Si-" structure. Due to the certain softness of the polysiloxane chain and the introduction of fluorine elements, it has extremely low surface free energy, which can reduce the surface tension of the coating system and effectively avoid the phenomenon of shrinkage holes caused by external environmental substances such as silicon particles and oil particles adhering to the newly applied coating film; on the other hand, the fluorosilicone polyether additive as a whole presents a three-dimensional network structure containing "-F-Si-", which has extremely strong permeability and can easily help the coating to spread quickly and smoothly after spraying, thereby improving the leveling speed of the coating system and effectively avoiding the phenomenon of shrinkage holes caused by the coating drying before it is fully leveled. Based on the above two points, the fluorosilicone polyether additive provided in the embodiment of the present application can effectively improve the anti-shrinkage ability of the coating system, thereby solving the technical problem that the existing coatings have poor appearance due to the generation of shrinkage holes. In addition, the side chains of the chemical components of the active substance in this fluorosilicone polyether additive are composed of non-polar, lipophilic hydrocarbon chains and polar, hydrophilic groups such as aldehyde groups, giving it dual hydrophilic and lipophilic properties. Even when the coating is exposed to residual fingerprints or moisture, it can still maintain excellent leveling, thereby achieving a very good appearance.

[0009] Compared to the currently commonly used leveling agents, the fluorosilicone polyether additive provided in the embodiments of the present application includes a polysiloxane main chain containing a "-F-Si-" structure, and a side chain composed of a non-polar, lipophilic hydrocarbon chain portion and a polar, hydrophilic group such as an aldehyde group, forming a three-dimensional network structure containing "-F-Si-" as a whole. When applied to coatings, it can not only avoid the shrinkage phenomenon of the coating film caused by external environmental substances with surface tension such as silicon particles in the air and oil particles, but also improve the leveling property of the coating system itself. From the two aspects of external environmental factors and the internal structure of the coating system itself, the anti-shrinkage ability of the coating system is effectively improved, thereby solving the technical problem of poor appearance of the coating obtained due to the generation of shrinkage holes in existing coatings.

[0010] Optionally, in some embodiments, n is 2-8.

[0011] By controlling the value of n, the main chain of the fluorosilicone polyether additive has an appropriate length, ensuring that it can effectively improve the anti-cratering ability of the coating system while having excellent compatibility with other components of the coating system.

[0012] Optionally, in some embodiments, R1, R2, R3 and R4 are each independently selected from an alkyl group, and n is 2-5.

[0013] When R1, R2, R3 and R4 are independently selected from alkyl groups, the value of n is preferably 2-5, so that the fluorosilicone polyether additive has a shorter main chain length, which can improve the compatibility of the fluorosilicone polyether additive with other components of the coating system.

[0014] Optionally, in some embodiments, R1, R2, R3 and R4 are each independently selected from an oxygen-containing group or a halogen, and n is 6-8.

[0015] When R1, R2, R3 and R4 are independently selected from oxygen-containing groups or halogens, the value of n is preferably 6-8, so that the fluorosilicone polyether additive has a longer main chain length, which can improve the leveling property of the coating containing the fluorosilicone polyether additive.

[0016] Optionally, in some embodiments, the alkyl group is preferably a C1-C4 alkyl group.

[0017] C1-C4 alkyl groups can improve the adaptability and compatibility of fluorosilicone polyether additives with other components of the coating system.

[0018] Optionally, in some embodiments, the oxygen-containing group is preferably selected from the following: carboxyl, hydroxyl, and propoxy.

[0019] The oxygen-containing groups can increase the ductility of the coating containing fluorinated silicone polyether additives on different substrates.

[0020] Optionally, in some embodiments, the halogen is selected from the following: fluorine, chlorine, bromine, and iodine.

[0021] Fluorine, chlorine, bromine and iodine can increase the permeability of coatings containing fluorinated silicone polyether additives on the substrate surface.

[0022] Optionally, in some embodiments, the weight concentration of the fluorosilicone polyether additive is 0.2 wt %-0.4 wt %.

[0023] When the weight concentration of the fluorosilicone polyether additive is less than 0.2 wt % or greater than 0.4 wt %, the leveling effect will be affected to a certain extent.

[0024] In a second aspect, the present invention provides an auxiliary agent composition, including the following components:

[0025] antifoaming substances, and

[0027] The additive composition provided in the embodiments of the present application, because it includes the fluorosilicone polyether additive described in the first aspect, possesses the advantages of the aforementioned fluorosilicone polyether additive. Furthermore, the addition of a defoaming agent effectively prevents the formation of craters due to surface drying of the coating before sufficient defoaming. The combined use of the two further enhances the anti-cratering capability of the coating system.

[0028] In some embodiments, the defoaming substance comprises a defoaming agent and / or an anti-foaming agent.

[0029] During the drying process, the paint is prone to bubbles due to a side reaction between the resin and water, which can cause shrinkage craters on the coating surface. The use of a defoamer in conjunction with the fluorosilicone polyether additive described in the first aspect is to prevent shrinkage craters that occur when the paint dries before sufficient defoaming has occurred. The addition of the antifoamer provides a stable anti-cratering effect.

[0030] Optionally, in some embodiments, the content of the defoaming substance is 0.1-0.5 parts by weight relative to 1 part by weight of the fluorosilicone polyether additive.
