The dry powder anti-mold agent for putty has the characteristics of broad-spectrum antibacterial, long-lasting anti-mold, safety and environmental protection. The following is a detailed analysis: The antibacterial spectrum is broad: The dry powder anti-mold agent for putty has a special effect on various molds, bacteria and yeasts, such as Aspergillus Niger, Aspergillus flavus, Aspergillus discolorius, Trichoderma, Mucor, Trichoderma pellicum

Surface coating: Suitable for post-processing antibacterial treatment. The adoption of plasma pretreatment technology to enhance the surface energy of TPE films can improve the adhesion of silver nanoparticle coatings.

In terms of composition, paper glue usually contains nutrients such as starch, protein and oil, which are precisely the "delicacies" needed for the growth and reproduction of mold. For instance, common glue is composed of polyvinyl alcohol, white latex, sodium stearate, talcum powder, urea, ethylene glycol, sucrose, flavoring, water, etc. Among them, components such as sucrose and protein provide rich nutritional sources for mold.

Silver ions/copper ions: Achieve broad-spectrum antibacterial effects by destroying the cell structure of microorganisms and are suitable for plastic handles. When adding, the dosage should be controlled (such as 0.3%-0.8%) to avoid the risk of yellowing or toxicity caused by the precipitation of metal ions. Nano zinc antibacterial agent: Utilizing nano zinc oxide technology, it is safe, environmentally friendly and has a high antibacterial efficiency. It is suitable for food contact grade materials (such as toothbrush handles) and can inhibit Escherichia coli, Staphylococcus aureus, etc.

Nanomaterials such as nano-zinc oxide and nano-titanium dioxide photocatalyze the generation of reactive oxygen species, which destroy the structure of biological cells. Or it can suppress adhesion through physical action, which is highly efficient, environmentally friendly and multi-functional. The preparation process is complex and the cost is relatively high

Adding antibacterial agents to ABS materials is an important means to enhance their antibacterial performance and expand their application fields. The following is an introduction from several dimensions including the types of antibacterial agents, application advantages, and application fields: Types of antibacterial agents for ABS materials

Types and mechanisms of action of antibacterial agents Silver ion antibacterial agent

In an environment with a temperature of 25-35℃ and a humidity of over 70%, microorganisms such as mold and yeast can form colonies within 24 hours, and their metabolic products can cause the following deterioration of the coating:

Polypropylene (PP), as an important general-purpose plastic, features excellent mechanical properties, electrical insulation, thermal stability and processing performance
