Abstract
The invention relates to a degradable cotton swab and a preparation method, and relates to the field of medical supplies, the degradable cotton swab is prepared from the following raw materials by weight: 110-130 parts of poly (butylene succinate), 70-90 parts of polylactic acid, 15-25 parts of a filler, 5-10 parts of a flexibilizer, 3-5 parts of a compatilizer, and 1-2 parts of a degradation accelerator; the preparation method of the degradable cotton swab comprises the following steps: S1, heating the poly (butylene succinate), the polylactic acid, the filler, the flexibilizer, the compatilizer, the degradation accelerant, an anti-static additive and an antibacterial agent to 120-150 DEG C according to a set proportion, and stirring for 20-25 minutes to obtain a blended material; S2, extruding and cooling the blended material to obtain a raw material rod; S3, cutting the raw material rod to obtain a formed cotton swab. The handle of the cleaning verification cotton swab can be degraded, and the cleaning verification cotton swab can have the antistatic and antibacterial effects at the same time.
Description
technical field [0001] The application relates to the field of medical supplies, in particular to a degradable cotton swab and a preparation method. Background technique [0002] Cleaning validation is documented evidence of the reproducibility and effectiveness of cleaning procedures for equipment surfaces that come into direct product contact. During the cleaning validation process, a large number of cleaning validation sampling cotton swabs will be used for professional sampling, and the analytical method must be successfully validated by the quality control department of the pharmaceutical company before use. Cleaning verification sampling cotton swabs are different from cotton swabs used in the general medical industry. They have higher requirements, no shedding impurities, low TOC, and should have no effect on sampling samples. [0003] The cleaning verification sampling cotton swab consists of a polypropylene handle and a polyester head sleeved at one end of the hand...
