Embodiment Construction

[0024] A kind of solution film masterbatch formula that can reduce antibacterial, comprises the component composition of following parts by weight:

[0025] Polyacrylate: 100~200 parts;

[0026] Polypropylene: 150~300 parts;

[0027] Starch: 50~100 parts;

[0028] Polylactic acid: 20~50 parts;

[0029] Slippery agent: 20~30 parts;

[0030] Antibacterial agent: 5~15 parts;

[0031] Synthetic vegetable ester: 5~50 parts.

[0032] The molecular weight of the starch is 10000-17000.

[0033] In the present invention, polyacrylate and polypropylene are selected as the base material, and through the addition of starch and polylactic acid, when polyacrylate and polypropylene are aggregated together, starch and polylactic acid are aggregated together in the middle. . At the same time, polypropylene and polyacrylate have good compatibility, so the two can be well mixed together during the blending process. At the same time, polyacrylates have carboxyl groups, while starch and po...

Abstract

The invention discloses a formula of a degradable antibacterial thin film master batch. The formula comprises the following components in parts by weight: 100-200 parts of polyacrylate, 150-300 parts of polypropylene, 50-100 parts of starch, 20-50 parts of polylactic acid, 20-30 parts of a smoothening agent, 5-15 parts of an antibacterial agent and 5-50 parts of synthesized stanol ester. The master batch prepared according to the formula has relatively good biodegradable ability and antibacterial performance.

Description

technical field [0001] The present invention relates to a medical product, and more particularly, to a thermoplastic elastomer tourniquet formulation. Background technique [0002] Biaxially oriented polypropylene film (BOPP) is generally a film, which is obtained by co-extruding polypropylene particles to form a sheet, and then stretching in both vertical and horizontal directions. Due to the orientation of the stretched molecules, this film has good physical stability, mechanical strength, air tightness, high transparency and gloss, and is tough and wear-resistant. It is currently the most widely used printing film, and the general thickness is 20~ 40μm, the most widely used is 20μm. The main disadvantage of biaxially oriented polypropylene film is poor heat sealability, so it is generally used as the outer film of composite film. For example, after compounding with polyethylene film, the moisture resistance, transparency, strength, stiffness and printability are all idea...
