Specifically, SMA is adopted as a polymer matrix, AgNO3 is added, nano silver is reduced by means of ultraviolet light, the nano silver with antibacterial performance is stably loaded on SMA colloidal particles through the complexation between carbonyl groups on an SMA anhydride ring and the silver, and the obtained silver nano colloidal particles are further added into an aqueous polyurethane coating system to replace conventionally used bactericides such as isothiazolinone and the like in the aqueous polyurethane coating.
Description
Technical Field
The invention belongs to the field of high polymer materials and nano materials, and particularly relates to a waterborne polyurethane coating.
Background
At present, the application range of the waterborne polyurethane coating is widened to various fields due to the excellent mechanical property, higher solid content and other properties of the polyurethane coating and the solvent-free and environment-friendly properties of the waterborne coating, and the waterborne polyurethane coating is mainly applied to wood coatings, automobile repairing coatings, anticorrosive coatings, floor coatings, electronic coatings and the like. At present, the mildew-proof bactericide is a kind of auxiliary agent commonly added in the waterborne polyurethane coating, and can endow the coating with certain antibacterial property. Isothiazolinones are commonly used, but these biocides are not ideally dispersed in some polyurethane systems, thereby affecting their biocidal properties.
The typical characteristic of nano silver is antibacterial property, and the sterilization mechanism of the silver is different from that of a chemically synthesized antibacterial agent and is mainly based on the denaturation of heavy metal ions on bacterial protein, so that the nano silver has the characteristics of broad-spectrum sterilization and less generation of drug-resistant bacteria. Under the condition of the same nano-silver concentration, the longer the action time is, the higher the bacteriostasis rate is. The nano silver has good thermal stability and still has good bacteriostatic effect after high-temperature treatment.
SMA (styrene-maleic anhydride copolymer) is a polymer material, which contains hydrophilic maleic anhydride elements and hydrophobic styrene elements in the structure, can be used as a polymer surfactant, a good dispersant, a compatilizer and the like, and can form nano colloidal particles in a certain solvent.

The invention solves the technical problems through the following technical scheme: the waterborne polyurethane coating is characterized by comprising the following components: the water-based polyurethane resin, silver nano colloidal particles and an auxiliary agent. Specifically, the feed additive comprises the following components in parts by weight: 100 parts of waterborne polyurethane resin, 5-10 parts of silver nano colloidal particles and 3-6 parts of an auxiliary agent. The auxiliary agent is one or more of defoaming agent, flatting agent, wetting agent, pigment, thickening agent and filler.
Wherein, the silver nano colloidal particles are prepared by the following processes:
(1) weighing 0.5-0.7g of macromolecular SMA, dissolving in 10-15ml of organic solvent, vigorously stirring, slowly dripping water (preferably ultrapure water), slowly dripping the solution into 100ml of water (preferably ultrapure water) when blue opalescence appears, and vigorously stirring to obtain the SMA nano colloidal particles. (2) And (3) taking 10ml of the SMA nano colloidal particle solution, dropwise adding 15 mu L of 0.2mol/L AgNO3 solution, wrapping the solution with tinfoil paper in the dark, stirring the solution for 3 hours under the action of magnetic stirring to fully mix the colloidal particles with silver nitrate, and then placing the mixture under an ultraviolet lamp for exposure to prepare the silver nano colloidal particle (nano SMA-Ag) solution.
The organic solvent in the step (1) is DMF. And (3) in the step (2), the exposure time under an ultraviolet lamp is 5-10 min.
The positive progress effects of the invention are as follows: (1) cheap polymer SMA is used as a matrix, and nano silver can be stably loaded on a polymer matrix carrier by utilizing the complexation between carbonyl and Ag on anhydride; (2) the nano silver is reduced from AgNO3 by means of ultraviolet irradiation, the load on SMA colloidal particles is realized, the preparation condition is mild, the light energy is fully utilized, the use of the traditional reducing agent NaBH4 is avoided, the environment is protected, and the short-time ultraviolet irradiation can not degrade the SMA; (3) the prepared silver nano colloidal particles are further added into a water-based polyurethane coating system, and acid anhydride in the SMA structure is partially hydrolyzed into carboxylic acid in an aqueous solution, so that a certain hydrogen bond effect can be formed with polyurethane, the compatibility is ensured, a stable system is formed, and the silver nano colloidal particles can replace the traditional bactericides such as isothiazolinone and the like.

Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1 preparation of silver nano colloidal particle solution
(1) 0.5g of macromolecular SMA (Mn & ltn & gt 100000) is weighed, dissolved in 10ml of organic solvent DMF, vigorously stirred, and at the same time ultrapure water is slowly dripped, when blue opalescence appears, the solution is slowly dripped into 100ml of ultrapure water, and vigorously stirred to obtain the SMA nano colloidal particles. (2) And (3) taking 10ml of the SMA nano colloidal particle solution, dropwise adding 15 mu L of 0.2mol/L AgNO3 solution, wrapping the solution with tinfoil paper in the dark, stirring the solution for 3 hours under the action of magnetic stirring to fully mix the colloidal particles with silver nitrate, and then placing the mixture under an ultraviolet lamp for exposure for 5 minutes to prepare the silver nano colloidal particle (nano SMA-Ag) solution.
Example 2 characterization of silver nanocolloid particle solution
The silver-loaded nano colloidal particle (nano SMA-Ag) solution prepared in step 2 of example 1 was diluted, and then dedusted with a 0.45 μm filter, and then the particle size distribution was measured by dynamic laser light scattering (DLS), and the results are shown in FIG. 1. And dropping a drop of the solution dedusted by the filter membrane onto a copper net, drying at room temperature for 1 day, and observing the morphology by using a TEM (transmission electron microscope), wherein the result is shown in FIG. 2. DLS results show that two peaks appear on the particle size distribution diagram, nano silver exists at the position of 8-12nm, and the peak appearing at about 70nm comes from SMA nano particles. TEM results show that the particle size of the nano Ag is about 8-16 nm (the SMA colloidal particles in TEM are unclear due to the contrast problem between Ag and the SMA colloidal particles), and TEM images show that the nano Ag can be well dispersed on the surface or around the SMA colloidal particles, because the SMA polymer contains a large amount of carbonyl groups and can be complexed with the nano Ag.
Example 3 preparation of aqueous polyurethane coating
Adding the silver nano colloidal particle solution prepared in the example 1 into the waterborne polyurethane resin, and adding an auxiliary agent, wherein the specific components are as follows: 100 parts of waterborne polyurethane resin, 5 parts of silver nano colloidal particles, 2 parts of a water-based defoaming agent and 2 parts of a flatting agent.
Example 4 preparation of aqueous polyurethane coating
Adding the silver nano colloidal particle solution prepared in the example 1 into the waterborne polyurethane resin, and adding an auxiliary agent, wherein the specific components are as follows: 100 parts of waterborne polyurethane resin, 10 parts of silver nano colloidal particles, 2.5 parts of water-based defoaming agent, 2 parts of flatting agent and 1.5 parts of thickening agent.
