Problems solved by technology

[0002] Among inorganic antibacterial agents, due to Ag + It has the characteristics of broad-spectrum antibacterial, high bactericidal efficiency, and is not easy to produce drug resistance. Therefore, silver-type antibacterial agents occupy an important position in antibacterial agents, but because the antibacterial effect of silver ions is greatly affected by light and heat, in the long-term use process Silver ions are easily transformed into brown silver oxide or reduced to black simple silver, which not only changes color, but also reduces the antibacterial effect

Abstract

Disclosed is an antibacterial surface decorative material and its preparation method, wherein the material comprises (by weight percentage) adhesive 100 parts, acicular zinc oxide crystal whisker antibacterial agent 0.1-10 parts, pre-dispersing agent 0.1-10 parts, auxiliary agent 0.1-5 parts. The preparing process consists of charging into a reaction kettle, stirring at 30-60 deg. C, and mixing the pre-dispersion system with other components.

Description

Technical field [0001] The invention relates to a surface decoration material and a preparation method thereof, in particular to an antibacterial surface decoration material and a preparation method thereof. Background technique [0002] Among inorganic antibacterial agents, due to Ag + It has the characteristics of broad-spectrum antibacterial, high sterilization efficiency, and resistance to antibiotics. Therefore, silver-type antibacterial agents occupy an important position in antibacterial agents. However, the antibacterial effect of silver ions is greatly affected by light and heat. The silver ion is easily converted into brown silver oxide or reduced to black silver element, which not only appears discoloration, but also reduces the antibacterial effect. The four-needle zinc oxide whisker (T-ZnOw) material is a new type of antibacterial material that has emerged in recent years. Due to the unique spatial three-dimensional four-needle structure and the tip nano effect of T-...
