Problems solved by technology

[0008] In order to solve these problems, the patent KR100048670 uses zeolite and anti-discoloration agent substituted by ammonium ions, but it cannot completely prevent discoloration, and it is easy to release ammonium when the resin is heated during processing, which leads to the problem that the resin is easy to foam
[0009] Patent KR100086520 proposes a method of coating paraffin oil on the surface of an inorganic antibacterial agent to solve this problem, but the disadvantage of this method is that it needs to increase the process required for coating, resulting in increased cost, and the thickness and degree of coating are not easy to adjust uniform
[0010] Patents such as JP4275370 propose that in order to prevent the problem of discoloration, a phosphate inorganic antibacterial agent with a strong binding force between the antibacterial metal component and the carrier can be used to solve this problem, but the stability of the antibacterial agent itself is greatly increased. The additives used to improve the physical properties of the resin interact to promote the oxidation / reduction of antimicrobial agents and cause discoloration

preparation example Construction

[0055] The preparation method of the resin composition with antibacterial activity and antistatic performance of the present invention, comprises the following steps: (1) general-purpose resin and dendrimers used as base resin, with the weight ratio of general-purpose resin and dendrimers as 90-99: 10-1 Mixing and extruding to obtain composite resin; (2) Mixing antibacterial agent and antistatic agent in the composite resin obtained in step (1), and the total weight of antibacterial agent and resin composition The percentage by weight is 0.01-10%, and the percentage by weight of the total weight of the antistatic agent and the resin composition is 5-25%, so as to obtain a resin composition with antibacterial activity and antistatic performance.

[0056] Step (1) The general-purpose resin used as the base resin is mixed and extruded to obtain a composite resin. The mixing temperature, mixing time and extrusion temperature are based on the type and use of the dendritic polymer re...

Embodiment 1

[0061] (1) Mixing and extruding 2 parts by weight of dendritic polymers and 98 parts by weight of polypropylene to obtain a composite resin. Dendritic polymers are prepared according to the method described in the patent KR100852384, mixing and The extrusion time is kept for 6-10 hours, the kneading temperature is kept at 80-100°C, and the extrusion temperature is kept at 180-220°C.

Abstract

The invention relates to a resin composition having outstanding antibacterial activity and antistatic performance by imparting antibacterial activity and antistatic performance to a composite resin comprising a dendritic polymer, a preparation method of the resin composition, and a product comprising the resin composition. The resin composition comprises composite resin, an antibacterial agent and an antistatic agent, wherein the composite resin comprises general-purpose resin serving as base resin and dendritic polymer; and the resin composition is spun to obtain woven cloth or non-woven fabric, the woven cloth or the non-woven fabric is made into operation cloth and other products, and the operation cloth and other products are endowed with semi-permanent antibacterial activity and antistatic performance, so that static electricity is prevented, adsorption of substances such as dust is further prevented, and bacterial infection caused by falling bacteria is prevented.

Description

technical field [0001] The invention belongs to the technical field of resin compositions, and in particular relates to a resin composition with antibacterial activity and antistatic performance, a manufacturing method thereof and products comprising the composition. Background technique [0002] Some products need to have antibacterial activity and antistatic properties at the same time. Surgical cloth is one of them. Surgical cloth is a general term for the cloth that is laid in advance on the operating table in the operating room to absorb blood or body fluids discharged during the operation. Surgery The importance of cloth is self-evident, and it is a very important part. [0003] All surgical knives in the operating room must be cleaned and disinfected. The surgical drapes that must be used in the operating room are also disposable products that have been sterilized. Bacteria cannot prevent cell infection. In order to prevent these situations and prevent problems befo...
