Embodiment 1

[0018] 3% of the antibacterial components, of which Ag 2 CO 3 The mass fraction of AgCl accounts for 35%, the mass fraction of AgCl accounts for 45%, and the mass fraction of Ag accounts for 20%. It is injection molded together with 97% ABS. In the tank, after 10 hours, the number of microorganisms such as bacteria and fungi in the water was reduced by 81.3%.

Embodiment 2

[0020] 5% of the antibacterial components, of which Ag 2 CO 3 The mass fraction of AgCl accounts for 45%, the mass fraction of AgCl accounts for 45%, and the mass fraction of Ag accounts for 10%. It is injection molded together with 95% PP, and the shape is a groove. Pour the mineral water that has been placed in the air for a week In the tank, after 10 hours, the number of microorganisms such as bacteria and fungi in the water was reduced by 83.6%.

Embodiment 3

[0022] 8% of the antibacterial components, of which Ag 2 CO 3 The mass fraction of AgCl accounts for 45%, the mass fraction of AgCl accounts for 50%, and the mass fraction of Ag accounts for 5%. It is injection molded together with 92% PC. The shape is grooved and the antibacterial components are mainly concentrated on the inner side of the grass body. Put the mineral water in the air for a week into the tank. After 9 hours, the number of microorganisms such as bacteria and fungi in the water was reduced by 86.5%.

Abstract

The invention relates to plastic used in drinking water bacteriostasis and sterilization. According to the invention, an antibacterial component containing Ag element is added during an injection molding process of a masterbatch. The plastic comprises Ag element. The Ag element can influence microbe growth and reproduction, leading to the death of the microbes. With the Ag element, cell wall synthesis can be interfered, cell membrane can be damaged, protein synthesis can be inhibited, nucleotide synthesis can be interfered, and genetic information replication can be hindered, such that good bacteriostasis and sterilization functions are provided. The plastic of the masterbatch can prevent the excess of silver element in water. The plastic provided by the invention can be widely applied in surfaces directly contacting drinking water, such as drinking fountains, water purification machines, water delivery pipes, and the like.

Description

technical field [0001] The invention relates to a plastic used for antibacterial and sterilizing drinking water, in particular to a plastic containing an antibacterial component of Ag element. Background technique [0002] With the development of modern industry, agriculture and urban modernization, the types of industrial wastewater and domestic sewage are also increasing. A large amount of urban wastewater is directly discharged without proper treatment, resulting in continuous pollution of domestic water sources. However, the treatment process of sewage treatment plants is relatively simple, and cannot remove all bacteria and microorganisms in the water. Moreover, after more than one month of use, a large number of fungi and molds will be parasitic and become a breeding ground for microbial growth. In the long-term evolution of microorganisms, chlorine-resistant pathogenic microorganisms such as Cryptosporidium have been produced. Traditional chlorine-containing disinfect...
