Problems solved by technology

However, ordinary aluminum composite panels currently on the market can no longer meet this hygienic performance requirement. If antibacterial aluminum composite panels are developed and industrialized, this will be a great deal for China, which ranks first in the world in terms of output, usage and export volume. Undoubtedly a very meaningful thing

Embodiment 1

[0034] First weigh 120KG of resin base material and put it in the material bucket, then add 50KG of solvent and stir at a low speed for 10 minutes, then add 5KG of film-forming aid, 1KG of leveling agent, and 10KG of pigment in turn. Stir at a medium speed for 10 minutes, then slowly add 5KG of compound antibacterial agent. At this time, it must be stirred at a medium speed for 5 minutes while adding, and then add part of the solvent and other additives with a weight of 3KG and stir at a medium speed for 15 minutes, then turn to Stir at high speed for 30 minutes, then turn to medium speed and stir for 5 minutes after the high-speed stirring is completed, and finally make the required antibacterial coating. The viscosity of this paint is 70-80 seconds / 25°C.

Embodiment 2

[0036] First weigh 200KG of resin base material and put it in the material bucket, then add 70KG of solvent and stir at low speed for 10 minutes, then add 7KG of film-forming aid, 3KG of leveling agent, and 50KG of pigment in turn. Stir at a medium speed for 10 minutes, then slowly add 10KG of compound antibacterial agent. At this time, it must be stirred at a medium speed for 5 minutes while adding, and then add part of the solvent and other additives with a weight of 4KG and stir at a medium speed for 15 minutes, then turn to Stir at high speed for 30 minutes, then turn to medium speed and stir for 5 minutes after the high-speed stirring is completed, and finally make the required antibacterial coating. The viscosity of this paint is 70-80 seconds / 25°C.

Embodiment 3

[0038] Microorganism Detection of Antibacterial Aluminum Composite Panel

[0039] According to JC / T897-2002, the antibacterial performance of the antibacterial aluminum composite panel was tested and analyzed, and the results are as follows:

[0040] Table 1

[0041]

[0042] The results show that the antibacterial aluminum composite board has good effects on anti-Staphylococcus aureus, anti-methoxy-resistant Staphylococcus aureus and anti-Escherichia coli.

Abstract

The invention discloses a complex antibacterial agent, an antibacterial coating and an antibacterial aluminum composite plate, and relates to an antibacterial agent, a coating composition containing the antibacterial agent and a laminar product consisting of flat thin layers. The complex antibacterial agent comprises silver-zinc titanium dioxide, zinc bromide and zinc pyrithione, and the mass ratio of the silver-zinc titanium dioxide to the zinc bromide to the zinc pyrithione is 7 to 1 to 1.5; the antibacterial coating contains the complex antibacterial agent with the mass percentage of between 0.24 and 18.9 percent; and the antibacterial aluminum composite plate comprises an aluminum panel and an aluminum bottom board, and the outer surface of the aluminum panel is coated with the antibacterial coating. The antibacterial performance of the antibacterial aluminum composite plate can reach the technical requirement of the national building material antibacterial standard JC / T 897-2002, and the antibacterial aluminum composite plate can satisfy the demand of the antibacterial performance of national building decoration materials and can also remedy the disadvantages of foreign sources of goods.

Description

【Technical field】 [0001] The invention relates to an antibacterial agent and a coating composition containing the antibacterial agent, and also relates to a layered product composed of flat thin layers. 【Background technique】 [0002] As a new type of high-grade curtain wall material and decorative material, aluminum composite panel is widely used by more and more people. Relevant surveys by the World Health Organization show that most infectious diseases are caused by pathogenic infections, especially nosocomial infections are the most common. Therefore, some special places with high requirements for hygiene and cleanliness and densely populated public places have higher hygiene requirements for curtain walls and decorative materials. However, ordinary aluminum composite panels currently on the market can no longer meet this hygienic performance requirement. If antibacterial aluminum composite panels are developed and industrialized, this will be a great deal for China, wh...
