Problems solved by technology

[0008] It can be seen from the above patents that the conditions for preparing guanidine salt polymer powder in CN101037503A and CN1350022A are relatively harsh and the process is relatively complicated; in CN1445270A and US7282538B2, the guanidine salt polymer needs to be made into antibacterial masterbatch, the steps are cumbersome and the cost is high; CN102453315A , CN102453316A needs to use sodium pyrithione, and the cost is higher; CN102453273A needs to operate at a certain temperature in the process of preparing antibacterial agent, the energy consumption is large, and the shape and particle size of the product after drying and crushing are not well controlled
[0009] Therefore, the current antibacterial agents may have various defects and are difficult to apply to the non-woven fabric preparation process, or they may be applicable but have problems such as cumbersome steps and high cost

Abstract

The invention belongs to the field of preparation of polypropylene non-woven fabrics, and relates to an antibacterial mildewproof polypropylene non-woven fabric and a preparation method thereof. The antibacterial mildewproof polypropylene non-woven fabric comprises polypropylene, a guanidine salt composite antibacterial agent, a mildewproof agent and other auxiliaries; the guanidine salt compositeantibacterial agent is prepared from, by weight, 100 parts of a guanidine salt polymer, 0.01-40 parts of zinc salt and/or copper salt, 0.1-10 parts of an anti-migration agent, 0.5-100 parts of nano-sized powder rubber and 0.1-10 parts of a dispersing agent. The non-woven fabric has good antibacterial and mildewproof performance, a long-lasting effect and good water resistance.

Description

technical field [0001] The invention belongs to the field of polypropylene nonwoven fabric preparation, and more specifically relates to an antibacterial and mildewproof polypropylene nonwoven fabric and a preparation method thereof. Background technique [0002] Plastic products are one of the most common and most contacted items in people's life and work. Because plastic products are easy to be contaminated and breed a variety of microorganisms during processing and use, pathogenic bacteria and molds have caused certain damage to people's health. hazards. In recent years, with the improvement of living standards and the enhancement of hygiene awareness, people pay more and more attention to the pursuit of a healthy living environment, and the demand for antibacterial material products is increasing, among which antibacterial plastic products occupy an important position. [0003] Polypropylene (PP), as a thermoplastic with excellent performance, non-toxic, heat-resistant,...
