Description
Technical Field
The application relates to the field of coatings, in particular to UV metal ink, a preparation method of the ink and conductive cloth.
Background
The conductive cloth is a conductive fiber cloth obtained by electroplating a metal coating on the fiber cloth and can be divided into nickel plating conductive cloth, gold plating conductive cloth, carbon plating conductive cloth, aluminum foil fiber composite cloth and the like. The conductive cloth is mainly used for shielding work clothes or shielding cloth in work of electromagnetic equal-height radiation.
The conductive cloth is usually colored by using paint or ink according to the use requirement; the main components of the traditional ink comprise ethanol, propylene glycol butyl ether, pigment, emulsion, defoamer, deionized water and the like, but the traditional ink is usually required to be thermally cured, so that a large amount of organic gas is easily generated, and the traditional ink is not environment-friendly and affects the health of workers; in addition, in order to improve the adhesive force of the ink, the baking time of the oven needs to be increased, and the equipment is large in size; most of the traditional ink is not resistant to corrosion of organic matters such as alcohol and the like, and is easy to cause a decoloring problem.
The ink is also UV ink, and the main components of the ink comprise prepolymer, reactive diluent, pigment, photoinitiator, polymerization inhibitor and the like, and the curing mode is UV curing; however, compared with the common fabric, after the UV ink is coated on the conductive cloth, part of the ink has the problems of easy decolorization and poor adhesive force.
Based on the problems, the shielding effect of the conductive cloth is considered, so that on the premise of not obviously improving the surface resistance of the conductive cloth, the conductive cloth with the characteristics of organic corrosion resistance, difficult decolorization and excellent adhesive force is prepared, and the method has positive significance for popularization and use of the conductive cloth.
Disclosure of Invention
The application provides a UV metal printing ink, a preparation method of printing ink and conductive cloth, and the printing ink is used for coating the surface of the metal-plated conductive cloth, has good organic corrosion resistance on the premise of not obviously improving the surface resistance of the metal-plated conductive cloth, is difficult to fade and has excellent adhesive force.
In a first aspect, the present application provides a UV metal ink, which adopts the following technical scheme:
the UV metal ink comprises the following raw materials in percentage by mass: 20-43% of acrylic resin, 20-30% of acrylic monomer, 11-15% of pigment, 2-7% of acrylic conductive silver colloid, 3-8% of acrylic dispersion loaded with nickel graphene, 1-4% of photoinitiator, 2-4% of light accelerator, 0.2-0.6% of defoamer, 2-6% of ethanol, 2-6% of propylene glycol butyl ether and 2-6% of water.
By adopting the technical scheme, the acrylic ester monomer is selected as the photo-curing monomer, so that the photo-curing monomer can better react with the photoinitiator and the photo-accelerator; meanwhile, the acrylic resin is used as matrix resin of the ink, and the conductive silver adhesive and the nickel-loaded graphene also use an acrylic group as a dispersion medium, so that the components of the ink can be well and uniformly dispersed; the nickel-loaded graphene and the conductive silver adhesive can be uniformly dispersed in the ink as conductive substances, so that the surface resistance of the ink on the conductive cloth can be reduced, and the ink can be uniformly colored. And the nickel graphene-loaded acrylic acid-based dispersion can be matched with other components, so that the corrosion resistance and oxidation resistance of the ink are improved, and meanwhile, the adhesive force of the obtained ink on the conductive cloth is very excellent. Therefore, the ink is used for coating the surface of the metal-plated conductive cloth, has good organic corrosion resistance on the premise of not obviously improving the surface resistance, is difficult to fade and has excellent adhesive force. In addition, the ink is combined by UV curing and thermal curing, so that the equipment is small in size; the printing ink of this application when solidifying, still has low VOC's advantage, environmental protection safety.
In a specific embodiment, the raw materials of the nickel graphene-loaded acrylic dispersion comprise the following components in parts by weight: 32-41 parts of nickel-loaded graphene and 30-40 parts of water-based acrylic resin.
In one specific embodiment, the preparation method of the nickel graphene-loaded acrylic dispersion comprises the following steps:
dispersing graphene oxide in water, and performing ultrasonic treatment to obtain graphene oxide dispersion liquid;
dispersing nickel nitrate in absolute ethyl alcohol, and carrying out ultrasonic treatment to obtain nickel nitrate dispersion liquid;
adding nickel nitrate dispersion liquid into graphene oxide dispersion liquid, carrying out ultrasonic treatment, then adjusting the pH value to 9.8-10, carrying out ultrasonic treatment, adding a reducing agent, uniformly mixing, reacting at 80-90 ℃, and centrifuging to obtain a reactant;
preserving heat of the reactant at 180-185 ℃, and finally cleaning and drying the reactant to obtain the nickel-loaded graphene;
and adding the nickel-loaded graphene into the water-based acrylic resin, and performing ultrasonic dispersion to obtain an acrylic-based dispersion of the nickel-loaded graphene.

Application example
The application example provides a conductive cloth, and the preparation method comprises the following steps:
UV printing: printing ink on a nickel-plated conductive cloth, wherein the nickel-plated conductive cloth is 300mm wide and 0.016mm thick, the printing speed is 10m/min, and the UV energy is 10KW and a mercury lamp are arranged.
And (3) heat curing: the speed after UV curing is unchanged, and the conductive cloth is obtained by heat-assisted curing at 70 ℃ through a 2m hot air drying tunnel.
Wherein the inks are derived from UV metal inks prepared in examples and comparative examples, see in particular Table 5. Meanwhile, conducting adhesive force detection, alcohol-resistant wiping detection and surface resistance detection on the conductive cloth.
1. And (3) adhesive force detection:
the surface of the sample was scribed with 10X10 1mm X1 mm grids with the blade perpendicular to the template, each scribe being deep and the bottom of the paint (scribed through the ink); cleaning fragments in the test area by using a hairbrush; sticking a tested area by using a 3M600# adhesive tape, and wiping the adhesive tape by using an eraser with 1.5Kg force so as to strengthen the force of the contact area between the large adhesive tape and the tested area; after standing for 1-2 minutes, the other end of the adhesive tape is grasped by hand, the adhesive tape is lifted instantly at a vertical (90 DEG), the test is repeated for 2 times at the same position, and the adhesive tape can be observed by using a magnifying glass.
Taking conductive cloth with the same application example, heating at 150 ℃ for 30min, cooling to room temperature, and repeating the adhesive force detection operation.
(2) Alcohol-resistant wiping detection: the sample was repeatedly wiped with absolute ethyl alcohol dust-free cloth 50 times to see if the ink turned off.
(3) And (3) surface resistance detection: the detection is carried out according to the method in GB/T30139-2013 general technical Condition for Industrial electromagnetic shielding fabrics.
The detection results are specifically shown in Table 5
Table 5 application example conductive cloth ink type and performance test table
As is clear from the detection results of application examples 1 to 4, the conductive cloth using the ink has surface resistance smaller than 0.07, excellent conductive performance, good adhesive force and alcohol resistance, and excellent adhesive force after being heated for a short time at 150 ℃. Wherein application example 1 is the most preferred embodiment. In addition, it was found by comparing the results of the tests of application examples 17 to 18 that the final properties of the ink were deteriorated regardless of whether the acrylic-based conductive silver paste was used alone or the nickel graphene-supported acrylic-based dispersion was used alone. In particular, in application example 17, the high temperature resistance was further lowered without using the nickel graphene-supported acrylic dispersion. Therefore, the nickel-graphene-loaded acrylic acid-based dispersion and the acrylic acid-based conductive silver adhesive are used together, so that the ink has lower surface resistance, better high-temperature resistance, better adhesive force and alcohol resistance, and can be better applied to conductive cloth.
As is clear from the detection result of application example 5, increasing the content of the conductive particles does not further decrease the surface resistance of the conductive cloth, but causes an increase in the surface resistance, which indicates how it is more important to make the conductive particles more uniformly dispersed in the ink system than to continuously increase the content of the conductive particles; therefore, the acrylic resin is used as matrix resin of the ink, the conductive silver colloid and the loaded nickel graphene also use the acrylic group as a dispersion medium, so that the loaded nickel graphene and the conductive silver colloid can be uniformly dispersed in the ink as conductive substances, and the usability of the ink is improved. From the detection results of application examples 14 and 15, it is known that the ratio of the nickel-loaded graphene to the conductive silver paste as a conductive material has a certain influence on the performance of the ink.
From the detection results of application example 6, it was found that although pure silver powder was used as the conductive particles, the adhesion was also excellent, and the surface resistance of the conductive cloth was also less than 0.07, but there was still no application example 1 in which the surface resistance was small, indicating that the use of the silver-loaded carbon nanotubes has a more positive significance to the performance of the conductive plate, probably because the silver-loaded nanotubes could be dispersed more uniformly and stably in the ink system.
As can be seen from the detection result of application example 7, the addition of the polyethylene glycol/polyamide amine copolymer improves the more performance of the ink, on the one hand, the polyethylene glycol/polyamide amine copolymer causes the conductive particles to be dispersed in the ink system more uniformly and stably; in addition, the polyethylene glycol/polyamide amine copolymer can adjust the viscosity and other properties of the ink, so that the ink can be better attached to the base cloth. And the performance of application example 7 was more excellent than that of application examples 8 and 9. Furthermore, the results of the test of comparative application example 10 revealed that if the performance of application example 10 and the performance of application example 1 were similar to each other, it was demonstrated that the carboxylated carbon nanotubes could be matched with the polyethylene glycol/polyamidoamine copolymer.
It is also evident from the results of the tests of application examples 11 to 13 that the algebraic amount of the polyamidoamine in the polyethylene glycol/polyamidoamine copolymer has a certain influence on the effect of the polyethylene glycol/polyamidoamine copolymer, which is probably because the algebraic amount of the polyamidoamine affects the combination of the polyethylene glycol/polyamidoamine copolymer with other substances, and the algebraic amount of the polyamidoamine affects the stability and dispersibility of the polyethylene glycol/polyamidoamine copolymer in the ink system. As is clear from the results, the ink performance was good when the number of polyamide amine generations was 4 to 5. Furthermore, it was found from the results of the test of application example 16 that the addition of pure polyamidoamine does not improve the performance of the ink well, probably because the polyethylene glycol/polyamidoamine copolymer acts better on the ink system after the polyethylene glycol has been modified with polyamidoamine.
The present embodiment is merely illustrative of the present application and is not intended to be limiting, and those skilled in the art, after having read the present specification, may make modifications to the present embodiment without creative contribution as required, but is protected by patent laws within the scope of the claims of the present application.
