Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood by those skilled in the art, the present invention is further described with reference to the accompanying drawings and examples.
As shown in FIG. 1, the present invention provides a method for enhancing the integrity and durability of a surface coating on a fibrous material, comprising steps S1-S3:
s1, pretreating the fiber material;
s2, performing surface chemical plating on the pretreated fiber material to form a chemical plating layer on the surface of the fiber material;
and S3, immersing the fiber material subjected to surface chemical plating into a PVA solution for coating, so that a PVA coating layer is formed on the surface of the chemical plating layer.
According to the invention, the PVA film is coated on the fiber material subjected to surface chemical plating, and the chemical plating layer of the fiber material is protected by the PVA film coating layer, so that the phenomenon that the chemical plating layer of the fiber material is largely peeled off can be avoided, and the integrity and the durability of the surface chemical plating layer of the fiber material are enhanced.
The invention can be applied to the preparation process of surface metallization by taking different fiber materials as a matrix, and the PVA film coating layer is utilized to protect the chemical coating layer so as to enhance the integrity and durability of the chemical coating layer on the surface of the fiber material. In a specific embodiment, the fiber material may be Kevlar fiber, or may also be other fiber materials such as nylon, dacron, and the like; surface electroless plating may be copper plating, zinc plating, nickel plating, and the like.
As shown in FIG. 2, in a preferred embodiment of the present invention, a method for enhancing the integrity and durability of a surface coating on a fibrous material includes steps S10-S30:
s10, pretreatment of the Kevlar fibers.
In this example, Kevlar fibres were pretreated using the following procedure:
s11, placing the Kevlar fiber in 45g/L sodium hydroxide solution, and ultrasonically oscillating for 30 minutes at the temperature of 45 ℃;
s12, placing the Kevlar fiber into a mixed solution of 45g/L stannous chloride and 20ml/L hydrochloric acid (the concentration of the stannous chloride in the mixed solution is 45g/L, and the concentration of the hydrochloric acid is 20ml/L) for 10 minutes;
s13, Kevlar fiber is put into sensitizing solution made of 0.5g/L palladium chloride and 10ml/L hydrochloric acid for 10 minutes. In the above steps S11-S13, after each step, Kevlar fibers are washed clean with distilled water.
And S20, performing surface chemical copper plating on the pretreated Kevlar fiber to form a chemical plating layer on the surface of the Kevlar fiber, thereby obtaining the chemically plated copper Kevlar fiber.
In this example, chemical copper plating was performed on the pretreated Kevlar fibers to form a copper plating layer on the surface of the Kevlar fibers, thereby obtaining electroless copper plated Kevlar fibers. The formula of the copper plating solution adopted by the electroless copper plating is 8g/L of copper sulfate, 38g/L of potassium sodium tartrate, 10ml/L of formaldehyde solution and 4.1g/L of sodium hydroxide.
And S30, immersing the chemical copper-plated Kevlar fiber into a PVA (polyvinyl alcohol) solution for coating, and forming a PVA coating on the surface of the chemical coating to obtain the PVA coated chemical copper-plated Kevlar fiber.
In the step, PVA is firstly put into distilled water at 95 ℃ to be hydrolyzed for 2 hours to obtain PVA solution, and then chemical copper plating Kevlar fiber is immersed into the PVA solution for film coating and is dried to obtain PVA film coating chemical copper plating Kevlar fiber. In this example, the concentration of the PVA solution was 5 g/L; in other embodiments, the concentration of the PVA solution may be 1g/L, 3g/L, 7g/L, or 10 g/L.
FIGS. 3-a, 3-b, and 3-c are surface topography maps of virgin Kevlar fiber, electroless copper plated Kevlar fiber, and PVA coated electroless copper plated Kevlar fiber, respectively. As can be seen from the figure, the original Kevlar fibres had a smooth surface, exhibiting a bright state; after electroless copper plating, the surface of the Kevlar fiber is attached by a copper plating layer and has larger particles, which is a phenomenon caused by automatic decomposition of a plating solution; after the PVA coating, the sample surface did not change much, but the surface clarity was slightly worse than when no coating was applied, because the conductivity was reduced after the PVA coating.
FIGS. 4-a and 4-b are surface topography maps of electroless copper plated Kevlar fiber and PVA coated electroless copper plated Kevlar fiber after bending peel tests, respectively. It can be seen that when no film is coated, the large-scale peeling phenomenon occurs on the surface of the coating after the sample is bent, and the falling is obvious; after PVA film coating, the surface of the coating has only a few cracks and has no large damage phenomenon.
FIG. 5 is a graph showing the change in surface unit resistance of electroless copper plated Kevlar fibers and PVA coated electroless copper plated Kevlar fibers, from which it can be seen that the surface unit resistance of the electroless copper plated Kevlar fibers is about 0.3 Ω/cm, indicating that the copper plating is relatively uniform and the conductivity is good; however, the hydrolysis concentration is less than 10g/L, the resistance change range is not large, and the PVA coating with the appropriate hydrolysis concentration has a certain protection effect on the plating layer and has little influence on the conductivity.
According to the embodiment of the invention, the chemical plating layer of the Kevlar fiber is protected by the PVA film coating layer through carrying out PVA film coating on the Kevlar fiber subjected to surface chemical copper plating, so that the phenomenon that the chemical plating layer of the Kevlar fiber is peeled off in large pieces can be avoided, and the integrity and the durability of the surface chemical plating layer of the Kevlar fiber are enhanced.
The foregoing is considered as illustrative of the preferred embodiments of the invention and is not to be construed as limiting the invention in any way. Various equivalent changes and modifications can be made by those skilled in the art based on the above embodiments, and all equivalent changes and modifications within the scope of the claims should fall within the protection scope of the present invention.
