Anti- biotic and mould proof resin molded body and air conditioner

Abstract

Provided is an anti-bacteria and anti-mold resin mold, usable as a drain plate for an air conditioner, for example, in which generation of slime in drain water can be restricted for a long period, andan air conditioner, in which failure due to slime is not generated. In this anti-bacteria and anti-mold resin mold, mix of anti-bacteria and anti-mold agent with wax and resin material are used for abase material, where dispersion quantity of the anti-bacteria and anti-mold agent is set to be 10-60 wt%, instead of addition of filler. The air conditioner comprises a resin mold for an air conditioner composed of the anti-bacteria and anti-mold resin mold.

Description

technical field

[0001] The present invention relates to an antibacterial and antifungal resin molded article with high molding accuracy and an air conditioner free from trouble caused by slime, which is used as a drain pan for an air conditioner that can suppress slime in drain water for a long period of time. Background technique

[0002] When the air conditioner is running, the air introduced into the machine is cooled by the heat exchanger, and at the same time, the moisture contained in the air is condensed on the surface of the heat exchanger. Condensed water (drainage) temporarily accumulates in the drain pan located below the heat exchanger, and is discharged out of the system by the drain pump and the drain pipe. However, microorganisms multiply in the drain water accumulated in the drain pan, and sometimes sticky Substance (slime). Slime created in the drain clogs the drain pump or drain pipe, quickly becoming the cause of air conditioner failures like drain leaks....

Embodiment

[0028] Example: Manufacture of an air conditioner drain pan dispersed with an antibacterial and antifungal agent

[0029] 80% by weight of zinc pyrithione, 18% by weight of polyolefin wax, and 2% by weight of synthetic resin lubricant were uniformly mixed at 70°C to prepare a mixture, and the mixture was mixed with polypropylene at a ratio of 1:1 at room temperature. Manufactured by injection molding figure 1 and figure 2 The dispersion amount of zinc pyrithione in the shape shown is a drainage dish of 40% by weight. The hardness (ASTM D 2240) of this drain pan is 70 to 72 (actual measurement value obtained by using a hardness meter D type manufactured by Polymer Meter Instruments Co., Ltd.), which is in a moderate hardness range (55 to 85) for elution of zinc pyrithione ( The hardness of the polypropylene molded body in which zinc pyrithione is not dispersed is 74-75).
