Anti-microbial plastic composition and washing machine comprising the parts manufactured by using the same

Abstract

Disclosed are anti-microbial composition, a washing machine including parts manufactured by the same, and a drum washing machine including a stand manufactutred by the same. The anti-microbial plastic composition includes 99.0-99.7% of polypropylene and 0.3-1.0% of an anti-microbial master patch, the anti-microbial master patch having 90% of polypropylene and 5% of isothiazolin compound, and 5% of inorganic compound or 89% of polypropylene, 5% of inorganic compound, and 1% of silver compound. The isothiazolin compound comprises 4,5-dichloro-2-n-octyl-4-isothiazolin-3-non of chemical fformula 1 and 2-N-octyl-4-isothiazolin-3-non of chemical formula 2 at a ratio of 4:1. The inorganic compound is zinc oxide. The washing machine in accordance with the present invention includes the anti-microbial plastic composition, and parts manufactured by the same such that the germs and fungus are prevented from being generated thereof. The drum washing machine in accordance with the present invention includes a cabinet divided into two drawers at the stand thereof.

Description

technical field [0001] The present invention relates to an antibacterial plastic composition and a washing machine comprising parts made of the composition, more particularly, to an antibacterial plastic composition comprising 99.0-99.7% polypropylene and 0.3-1.9% antibacterial masterbatch and a A top-loading washing machine and a drum washing machine including parts made of the antibacterial plastic composition, and a drum washing machine including a machine base made of the antibacterial plastic composition. The antibacterial masterbatch of the present invention comprises 90% polypropylene, 5% isothiazoline compound and 5% inorganic compound, or 89% polypropylene, 5% isothiazoline compound, 5% inorganic compound and 1% silver compound. Isothiazoline compounds include 4,5-dichloro-2-N-octyl-4-isothiazoline-3-DCOIT and 2-N-octyl-4-isothiazoline-3-OIT, the ratio of the two 4:1, and the inorganic compound contains 5% zinc oxide. Background technique [0002] In general, a wa...

Problems solved by technology

In the case where the structural elements are made of plastic, there is the problem of the growth of bacteria such as microorganisms due to nutrients or pollutants from the detergent and laundry, and the contamination of washed laundry due to contamination of the washing machine. pollution problem

[0030] Moreover, from a hygienic point of view, there is a problem in that although other structural parts of the washing machine are used in the washing machine at positions indirectly related to washing, fungus or other bacteria may grow during washing due to splashed washing water on other structural components
