Problems solved by technology

[0003] Currently commonly used antibacterial agents such as quaternary ammonium salts and metal ions (such as silver ions) are attached to the interior or surface of the material through ordinary blending, coating or spraying processes, but due to their low molecular weight natural properties, it is usually difficult to better Bonded to the material matrix, migration or leaching will generally occur during use, resulting in a decrease in antibacterial effect

Embodiment Construction

[0024] The present invention will be further described below in conjunction with embodiment, but protection scope of the present invention is not limited to this:

[0025] Step 1: Preparation of antibacterial thermoplastic starch granules:

[0026] Table 1 embodiment 1-6 prepares the required amount of each component of antibacterial thermoplastic starch granule

[0027]

[0028] The preparation method of antibacterial thermoplastic starch granules: take the required amount of each component in Table 1, and then prepare antibacterial thermoplastic starch granules as follows:

[0029] Starch, polyhexamethylene monoguanidine hydrochloride aqueous solution with a mass concentration of 36% and glycerol are mixed and stirred uniformly to obtain a mixture, and the mixture is kneaded, melted, extruded and granulated to obtain antibacterial thermoplastic starch granules.

[0030] The operating conditions for the preparation of antibacterial thermoplastic starch granules are as fol...

Abstract

The invention discloses a migration-free antibiotic polyolefin film and a preparation method thereof, and belongs to the antibiotic field. The method comprises the steps of: mixing starch, high-molecular polymer sterilization disinfectant aqueous solution and glycerinum, stirring uniformly, and thereby obtaining a mixture, and then blending, fusing, extruding and pelleting the mixture, thus obtaining antibiotic thermoplastic starch particles; mixing polyolefin, thermoplastic starch particles and bulking agent, stirring uniformly, and then blending, fusing, extruding and pelleting, thus making into antibiotic polyolefin particles; making the obtained antibiotic polyolefin particles into migration-free antibiotic polyolefin film by using the film blowing technology. The migration-free antibiotic polyolefin film produced by the method provided by the invention has good antibiotic effect, in addition, the antibiotic constituents in the antibiotic film has good migration resistant performance.

Description

technical field [0001] The invention belongs to the field of antibacterial, and in particular relates to a non-migration antibacterial polyolefin film and a preparation method thereof. Background technique [0002] With the increasing awareness of high hygiene level, prevention of disease spread and microbial contamination, antimicrobial activity becomes a very important feature of new materials, at the same time, the emergence of antibiotic resistant bacteria presents new challenges for the development of antimicrobial agents and antimicrobial materials. requirements. Compared with low-molecular-weight biocides, antibacterial agents and antibacterial materials prepared from polymer materials have fewer drug resistance problems, higher antibacterial activity and lower residual toxicity, so the preparation and application of antibacterial polymers have gained More attention. In addition, traditional low-molecular-weight antibiotics (such as ciprofloxacin) kill bacteria by p...
