Problems solved by technology

[0003] Patents CN1569923A, CN1445270A and US 7282538B2 introduced a processing method in which guanidinium salt polymers were first made into antibacterial masterbatches, and then used to prepare antibacterial plastics. The single guanidinium salt polymer group was analyzed quickly, which could not meet the antibacterial requirements of wading products. Product performance requirements with high durability requirements
[0004] Patent CN1282698C introduces a preparation method of polyolefin functional masterbatch, which adds guanidinium salt polymer components to polyolefin materials through a grafting process, which is difficult in process control and poor in product stability
[0005] Patent CN101724284B introduces an antibacterial thermoplastic composition and its preparation method. Its composite antibacterial component contains micro-nano inorganic or organic particles and guanidinium salt polymer. Technological requirements, but cannot meet the filament processing
[0006] Patent CN102644162B introduces a preparation method of antibacterial non-woven fabric based on nano-silver elemental antibacterial agent. The anti-bacterial masterbatch containing nano-silver prepared by this method has good performance in non-woven fabric processing, excellent anti-bacterial effect, and hygienic safety. Extremely high, but in the application practice, it is found that the control requirements of 80-100nm nano silver single substance powder are relatively high during the preparation process, and the product performance stability is not good

Abstract

The invention relates to quick-acting antibacterial functional master batch for a polyolefin filamentous material as well as a preparation method and an application of the master batch. According to the method, nano-silver inorganic antibacterial master batch in ZL201310571129.3, a guanidine salt polymer, polyolefin carrier resin, a stabilizer and a dispersant are mixed, double-screw melt extrusion and granulation are performed, and the quick-acting antibacterial functional master batch is prepared. The prepared quick-acting antibacterial functional master batch has good drawing or spinning performance in the processing process of the polyolefin filamentous material and has longer net change period and spinning assembly change period than those of other similar antibacterial master batch.The antibacterial polyolefin filamentous material prepared with the method contains nano-silver and guanidine salt polymer binary compound synergistic antibacterial components and thus has high antibacterial quick-acting performance, good washing durability and good whiteness and is applicable to production and processing of antibacterial products such as non-woven fabric of disposable medical health supplies, bath balls / bath towel for bathing, artificial turf filaments and carpets.
