を添加しても完全な黒色成形品にはならない。BACKGROUND OF THE INVENTION Composite resins containing inorganic fillers and the like are generally colored by adding pigments, and depending on the purpose, other dispersants, antistatic agents, etc. are added and molded. In particular, carbon black is used as a pigment as a black coloring material. However, when pigments such as carbon black are mixed, the dispersibility is extremely poor, and carbon black must be processed with a dispersant or mixed with resin at a high concentration beforehand, which increases the number of steps. may become necessary and the cost will increase. Also, if these processed pigments are blended at high concentrations, the physical properties will deteriorate. Also, unlike carbon black, unburned waste contains a wide variety of components, so it may not be possible to use it as a black coloring agent if it is used as is, no matter how much carbon black is added to it later. It will not be a completely black molded product.

However, in this case, unlike carbon black, it contains a variety of components, so processes such as water washing and drying are necessary to remove them, and other additives are also mixed in to improve dispersibility. Therefore, although the number of steps increases and waste is used, there is no cost advantage to using it as a practical matter, making it difficult to put it into practical use.

要である。[0006] The combustion ash used here is ash generated when combustible materials are burned in a fluidized bed boiler, pulverized coal boiler, or the like. The ash composition of this combustion ash depends on the combustible material used, but from the viewpoint of stability of the ash shape, it is preferably ash that is emitted when a combustible material containing 10% by weight or more of coal is burned. The particle size of this combustion ash is 1 to 2 on average by weight.
A material with a diameter of 0 μm can be used. If the particle size of the combustion ash exceeds 20 μm, the dispersibility in the resin will deteriorate and the physical properties of the molded article will deteriorate, which is not preferable. Further, if the particle size of the combustion ash is less than 1 μm, it is not preferable because it does not exhibit any effect as a filler and becomes a fine powder, making it difficult to handle. Furthermore, this combustion ash is porous and has a specific surface area of 9 x 10 cm/

。[0007] This combustion ash usually contains carbon as unburned matter. This is a component caused by coal, paint, resin, and other organic substances burned during incineration that are not completely combusted and remain in the combustion ash in the form of carbon.It is the main component that gives the black color and is equivalent to a coloring agent. It is. Therefore, it is necessary that 2 to 30% by weight of carbon be present in the combustion ash. If the amount of carbon is less than 2% by weight, it will be difficult to color the resin black. Moreover, if it exceeds 30% by weight, the effect may be saturated or even deteriorate, which is not preferable. The amount of carbon can be calculated from the amount reduced by further igniting and burning the combustion ash obtained normally.

るためには必要である。[0008] Since this carbon is attached and dispersed in other combustion ash, it does not exist as a fine carbon powder, so this combustion ash can be easily dispersed in the resin and colored in the same way as a carbon black masterbatch. can do. The combustion ash also contains TiO2 and Fe2O3. This is mainly due to pigment components contained in the waste, and if present in large amounts, the black tone changes. That is, TiO2 is a main component of what is normally used as a white pigment, and if a large amount of TiO2 is present, the colored product becomes gray, making it difficult to achieve a black tone. On the other hand, Fe2O3 is the main component of the red pigment, and if it is included in a large amount, the black tone will change, which is not preferable. Therefore, the total amount of both in the combustion ash is 10
It is necessary to keep the amount below % by weight in order to develop a black tone in the molded product.

This is the total amount obtained by actually measuring the combustion ash content mainly using fluorescent X-rays. To satisfy the above conditions, Ti and Fe in the coal must be
It is desirable to use a material whose total amount is 3% by weight or less. Further, it is desirable to use waste in which the total amount of Ti and Fe is 5% by weight or less. By increasing the ratio of coal to waste at a ratio of 1:2 or more and burning the waste at a temperature of 1000° C. or lower, combustion ash containing predetermined components can be obtained.

するために好ましい。。[0010] In addition to the above-mentioned components, this combustion ash contains various kinds of inorganic oxides, including alumina, silicon dioxide, and calcium oxide as main components, and other inorganic oxides as minor components, as shown in Table 1. This combustion ash can be added in an amount that does not exceed 60 parts by weight per 100 parts by weight of the resin. At that time, the amount of carbon in the resin is 0.4 to 6% by weight.
In order to maintain the color tone and physical properties, it is preferable to mix the amount so that the amount is less than 10%. .

To add this combustion ash to the resin, either mix it for a predetermined time with a mixer such as a V-type mixer, W-type mixer, cylindrical mixer, or Henschel mixer, and then extrude it with an extruder.
A method of adding the resin through a vent and mixing while kneading the resin with an extruder or the like can be applied. At this time, other additives such as plasticizers, stabilizers, lubricants, and dispersants may also be added.

物性の低下も少ない。[0012] By simply blending this combustion ash into a resin, both a coloring effect and a filling effect can be obtained. Therefore, there is no need to separately mix and disperse pigments and fillers, and there is little deterioration in physical properties.

なっているものと推定される。[Function] The black coloring filler of the present invention is combustion ash containing a specific coloring component, so it has a filling effect and a coloring effect at the same time. That is, the carbon contained in the combustion ash serves as a coloring material, and the total amount of other ash serves as a reinforcing agent. Furthermore, it is presumed that because carbon is retained in the porous body formed from other ash, it is easily dispersed into the resin.

For other compositions, the weight excluding the carbon amount from the whole is taken as 100% by weight.

The molded product is colored black, has an excellent appearance, and has a high Izod impact value. (Comparative Example) For comparison, a case where the total amount of TiO2 and Fe2O3 was large, a case where the amount of carbon was outside the range, and a case where conventional calcium carbonate and carbon black were blended were similarly evaluated. The results are shown in Table 3.

When 2% by weight of carbon black was added to No. 10 g of combustion ash, coloring was possible, but the impact strength was lowered by the addition of carbon black (the amount of filler was the same as No. 10).

している。(Test Example) TiO2 and Fe2 in combustion ash
Figure 1 shows the relationship between the amount of O3 and the color tone.If the vertical axis is the amount of TiO2 and the horizontal axis is the amount of Fe2O3, then if it is below the straight line connecting 10% by weight of each amount, then This shows that the black color tone is satisfactory. That is, it shows that the total amount of both should be 10% by weight or less.

剤として有用であることを示している。FIG. 2 also shows that when the amount of filler is kept constant and the amount of carbon or carbon black contained in the resin is increased, the same effect occurs in the case of combustion ash, which corresponds to the filler, and in the case of calcium carbonate. Izod impact value is reduced. However, in the case of combustion ash, the degree of decrease is smaller than in the case of calcium carbonate, as shown in the graph of FIG. Therefore, the combustion ash specified in this invention has been shown to be useful as a filler for black coloring.

るので樹脂中への混合や分散性の点でも優れている。Effects of the Invention It has been known that when carbon black is added to a resin containing an inorganic filler, the physical properties, particularly the impact strength, are reduced. However, in the resin composition containing the black coloring filler of the present invention, the degree of deterioration of physical properties is significantly lower than that of conventional compositions. Furthermore, since the filler itself can be colored, it is also excellent in terms of mixing and dispersibility into the resin.
