Problems solved by technology

Although the present invention has an antibacterial effect by improving the traditional formula and adding a special graphene nano-silver dispersion in the formula, the raw materials used in this invention are graphene and nano-silver, and graphene is currently used more in aerospace or aviation equipment In fact, the reason is that it is expensive, and its application to the coating of this invention will inevitably increase its production cost and reduce the market demand for coatings.

preparation example Construction

[0032] A preparation method for antibacterial nano-coating, comprising the following specific steps:

[0033] 1), prepare four kinds of nano dispersions

[0034] a. Add the deionized water and the wetting and dispersing agent of the component amount sequentially (by weight percentage) and stir evenly, and slowly add the nano powder while stirring;

[0035]b. After the powder is added, disperse at high speed for 30 minutes, turn on the nano-grinder, carry out circular grinding, and take samples at intervals for inspection. When the median particle size (D50) is between 40 and 80 nm, stop the machine to obtain nano-slurry and nano-dispersion The particle size distribution is uniform and very stable, with a long shelf life at room temperature and good compatibility with most film-forming substances;

[0036] 2), preparation of antibacterial nano coating

[0037] a, the nano-rice husk-nano-silver dispersion, nano-ATO dispersion, nano-LaB prepared in step 1) 6 Dispersion, Nano W...

Embodiment 1

[0042] A preparation method for antibacterial nano-coating, comprising the following specific steps:

[0043] 1), preparation of nano-dispersion

[0044] a. The preparation process of nano-ATO dispersion is as follows: 66% deionized water, 2% wetting and dispersing agent (T90), 7% wetting and dispersing agent (AFCONA4560), 25% nano-ATO powder, and deionized components are added in sequence Water, wetting and dispersing agent and stirring evenly, then slowly add nano powder while stirring, after the powder is added, disperse at high speed for 30 minutes, turn on the nano grinder, and carry out circular grinding, the grinding time is about 13-15 hours, and the median Nano-ATO dispersion with a particle size of about 75nm and a solid content of 25%;

[0045] b. The preparation process of nano-rice husk-nano-silver dispersion is as follows: deionized water 64%, wetting and dispersing agent (BYK90) 2%, wetting and dispersing agent (AFCONA4560) 7%, nano-rice husk-nano-silver powder...

Embodiment 2

[0053] The steps of this example are the same as the preparation process of Example 1, and the proportioning ratio of each component of the antibacterial nano-coating is listed in Table 1.

Abstract

The invention discloses an antibacterial nano-coating, a preparation method thereof, and an antibacterial nano-coating cloth. The coating includes, by weight, 20-40% of aqueous acrylic resin, 10-20% of aqueous amino resin, 15-30% of ATO nano-dispersion, 5-10% of LaB6 nano-dispersion, 5-15% of WO3 nano-dispersion, 0.5-1% of a leveling agent, 0.5-1% of an antifoaming agent, 10-20% of deionized water, and 0.5-1% of nano-rice husk-nano-silver dispersion, wherein a mass ratio of nano-rice husks to nano-silver is (20-50):1. The rice husks adopted as a component raw material has wide sources, is cheaper than graphene, greatly reduces the production cost, and has an antibacterial effect, and small amounts of granular carbon and silica play a role in skeleton to improve the impact strength of the coating.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular relates to a widely used antibacterial nano-coating and a preparation method thereof, and also relates to a coating based on the antibacterial nano-coating. Background technique [0002] Coating is one of the indispensable materials for the development of the national economy. It is a material that can be well bonded with the base material and form a complete and tough protective film when painted on the surface of an object. Due to the many special functions of the coating, there are various types of coatings. [0003] At present, there are nearly a thousand kinds of coatings that have been issued by the Ministry of Chemical Industry on the market, and they can be classified according to their functions. One of the antibacterial coatings has a good antibacterial effect and is widely used, such as Chinese invention patent (CN105419495A ) discloses an architectural c...
