Embodiment

[0107] The following examples are given to describe the present invention in more detail. However, the present invention is not limited by the following examples.

[0108] (sample preparation 1)

[0109] Various samples of Examples 1 to 4 and Comparative Example 1 were prepared according to the compositions shown in Table 1. The preparation method is as follows: First, components other than the isocyanate component are mixed with the polyol component, and then the polyol component and the isocyanate component are mixed and reacted. Various samples were prepared by heating in a heating furnace at 60 to 75° C. for 10 minutes for aging.

[0110]Moreover, BORANORU V3022J (trade name) manufactured by Mitsubishi Chemical Industry Co., Ltd. and MN700 (trade name) manufactured by Mitsui Takeda Chemicals, Inc. were mixed in equal amounts as a polyol component and used. In addition, toluene diisocyanate (TDI-80) was used as the isocyanate component. As a catalyst component and charc...

Abstract

The present invention provides one kind of foamed polyurethane plastic with excellent stink and moisture adsorption or excellent antibiotic property, and the foamed polyurethane plastic has visible compounded deodorant, antiseptic and other additives. The foamed polyurethane plastic features that it contains carbon powder and/or inorganic antiseptic and is preferably foamed polyurethane plastic with rebound elasticity.

Description

technical field [0001] The present invention relates to polyurethane foams having deodorant or antibacterial properties. More specifically, the present invention is to provide an additive that is excellent in absorbing or antibacterial properties for odors, moisture, etc., and at the same time allows users to visually recognize that a deodorant, antibacterial agent, etc. is added to polyurethane foam. of polyurethane foam. Background technique [0002] Polyurethane foam is widely used in various fields as shoe soles and insoles, bedding such as mattresses and pillows, cushioning materials for home chairs and car seat cushions, and as bed and wall materials. [0003] When polyurethane foam is used as a cushioning material for bedding such as mattresses or pillows, chairs for household use, and seat cushions for cars, it is easy to lose moisture due to sweating of the user and moisture in the air in high-temperature and high-humidity environments such as summer. produce mite...
