Particle size] in m + + carbon The main purpose of the powder is to make the whole polyurethane foam plastic to have a roughly uniform black color. When the particle size is less than 〇 · 〇 丨 # m, it is difficult to prepare the dispersion, and it is difficult to disperse approximately evenly when it exceeds 1 V m, so It is difficult to obtain a coloring effect.

When 1 to 5 0 0 // m carbon powder is mixed, it is better to use 丨 0 to 4 00 // m, and more preferably 100 to 300 / zra. The main purpose of blending 1 ~ 500 // m carbon powder is to obtain the deodorizing effect and hygroscopic effect of the carbon powder. When the particle size is 1 # m or less, the deodorizing effect and the moisture absorption effect are reduced, and when the particle size is 500 # m or more, it cannot be dispersed and retained in the foam, so it is not suitable.

Regarding the carbon powder, the log was burned at 75 0 to 1 2 0 ° C and then charred at 3 50 to 520 ° C, or the log was burned at 400 to 7 5 0 ° C and then 2 5 0 ~ 4 5 0 ° C black carbon obtained by carbonization, both can be used. For example, in the case of white borer, for example, quercus phillyraeoides is used as a log at 1200 ° (: long and long-burning binchotan charcoal. As for black borer, for example, Quercus acutissima), green Quercus serrata, etc. are the charcoal of the logs. In addition, bamboo charcoal, carb omb 1 ack, or activated charcoal, which are of the genus Gramineae, are also applicable. In the present invention, particularly It is better to use porous carbon powder such as charcoal and bamboo charcoal, and it is better to use long carbon. In the present invention, it is also possible to use charcoal and / or a mixture of bamboo charcoal and carbon black. The reason is that the charcoal and bamboo charcoal are the result of mixing carbon black The dispersibility is good. As a result of blending carbon black, the whole polyurethane foam plastic is colored black to make the visual effect of the inorganic fungicide good. The particle size of carbon black is not particularly limited. The ratio of the ratio of woody and / or bamboo and carbon black is not particularly limited. In terms of weight ratio, it is charcoal and / or bamboo charcoal: carbon black = i:. 5 to 5, and , 1.1.5 ~ 2.5 is better. Carbon black When the total amount is less than 0.5 weight times of the charcoal and / or bamboo blend, the effect of blending carbon black cannot be obtained. However, the amount of black blend exceeds 5 weight times of the blend of charcoal and / or bamboo charcoal. ! 柄 木 ί = or the relative reduction of the amount of bamboo charcoal to reduce the hygroscopicity and deodorization, so it is not suitable.

Page 17 200530311 V. Description of the invention (13) The blending amount of the carbon powder is preferably from 0.01 to 30% by weight based on the total composition. This is because when the blending amount of carbon powder is less than 0.01% by weight, the effect of blending carbon powder cannot be obtained, and when it exceeds 30% by weight, poor foaming may occur due to poor dispersibility, so neither is suitable. Furthermore, when the particle diameter of the carbon powder is 0. 1 to 1 // m, 0.1 to 20% by weight is preferable, and 0.5 to 15% by weight is more preferable. When the particle diameter of the carbon powder is 1 / z m or more, it is preferably 0.1 to 10% by weight, and more preferably 0.5 to 5% by weight. The polyurethane foam of the present invention contains an inorganic fungicide.

The inorganic germicidal agent used in the present invention is preferably a metal ion germicidal agent, and examples thereof include silver, copper, zinc, and titanium dioxide. In the present invention, it is particularly preferable to mix silver and / or titanium dioxide. The reason is that silver or titanium dioxide has good antibacterial activity. When combined with toner, more excellent antibacterial effect can be obtained. Further, in the present invention, it is preferable to use silver and titanium dioxide as inorganic germicides at the same time. The reason is that when silver and titanium dioxide are mixed together, it is possible to obtain particularly excellent antibacterial properties as compared with when they are mixed separately.

1〜10 重量 ％ 更。 The amount of inorganic fungicide blending is not particularly limited, is 0.01 to 30% by weight of the total composition, and 0.1 to 10% by weight is better. When the content is less than 0.01% by weight, the antibacterial activity cannot be imparted to the polyurethane foam, and when it exceeds 30% by weight, foaming in the production of the polyurethane foam may be hindered, and Sometimes the plastic comes off from polyurethane foam. In addition, when silver and titanium dioxide are used as an inorganic fungicide at the same time, the mixing ratio is not particularly limited, but the total of the above silver and titanium dioxide is blended.

The particle size of the inorganic bactericide is not particularly limited. 4 "," MA υ · 1 ~ 300 # Π1, ΪΓΛ ~ "Γ. In addition, the particle size of the inorganic bactericide should be smaller than the latter two, and smaller. The reason is that the carbon powder can carry the inorganic bactericide, and at the same time, it is excellent in the visual effect that the user mixes the plate powder. Redstone and brookite type titanium dioxide, but anatase is used. Also, "Ti oxide exists in titanium dioxide such as ruin type and gold. The present invention can use any type of mineral titanium dioxide, which has excellent antibacterial activity and is suitable.

In the present invention, only one of the carbon powder or the inorganic fungicide may be blended, or the carbon powder and the inorganic fungicide may be blended at the same time. Furthermore, in the present invention, it can be re-dispersed on the surface of porous carbon powder or re-dispersed on the surface of porous carbon powder or fruit's inorganic fungicide. Sex. The organic fungicide is carried in porous carbon powder and foam plastic. The fine pore surface of the inorganic fungicide is divided into carbon powders. At the same time, because of the ratio of the porous carbon powder to the organic fungicide, the antibacterial property and anti-odor are improved. When the inorganic fungicide is carried in the porous carbon powder, The particle size of the evening carbon powder should be larger than the particle size of the inorganic fungicide. ', Xi Kong ^ There is no particular method for supporting inorganic fungicides in porous carbon powder. For example, if the carbon powder and the inorganic fungicide are mixed in water and carried, or if the powder is Raw wood flour, etc. are mixed with an inorganic fungicide and burned and carried at 500 ° C (rc temperature). When wood flour is mixed with an inorganic agent, clay or an adhesive can be added as needed. And other preservatives.

Description of the invention (15) Furthermore, in the present invention, the method for sterilizing the inorganic sterilization surface or the inner surface of its pores can be carried out by the method of supporting carbon powder surface, non-electrolytic plating method, evaporation method, etc. . The above-mentioned inorganic germicidal agent and carbon powder can be used in the precipitation method and fumed graphite. However, in the present invention, it is especially blended in the above-mentioned range: 篁, that is, the germicide and carbon powder are used at the same time. It is advisable to mix the weight ratio of inorganic killer 1 ~ 5 inside. The reason is% to 10, and it is preferred that when the inorganic fungicide is added in an amount of 0.1 times the weight of the inorganic fungicide, the powder does not reach the visual effect of the fungicide. In addition, the toner rubbing amount and the amount of m combined with the inorganic material are also poor. In view of the blending amount of the inorganic fungicide, Figs. 1 to 4 are schematic diagrams showing the cross sections of the materials related to the present invention. In addition, as shown in Figure = = vinegar foam contains stone powder (3). Zhan Shiba ’s material (2) is known to swim plastic, but in polyurethane: B carbon powder inorganic fungicide.
