いて開示されている。2. Description of the Related Art In recent years, from the viewpoint of effective use of resources, various techniques for reusing glass powder generated in a glass manufacturing process and waste glass such as glass bottles that cannot be recycled as bottles have been proposed. There has been proposed a technique in which waste glass is crushed, that is, glass cullet is mixed with clay such as bentonite used as a binder or a ceramic raw material and fired to obtain a fired product, which is used as a building material or the like. Such technology is described in, for example,

くの問題があった。However, firing glass cullet using clay as a medium requires a temperature of about 1000 ° C. to 1300 ° C., which is the sintering temperature of clay.
In order to maintain such a high temperature for a predetermined time required for sintering, enormous energy is consumed, and when the temperature rises, the amount of CO 2 emitted increases and the load on the environment increases, Clay is a finite natural resource and may be depleted and may destroy nature during its collection. In addition, if the clay itself is expensive, the fired material will be expensive There were many problems.

重要な課題である。[0004] When glass cullets are sintered alone, there is a problem that the glass cullets are fused with each other to include voids inside the glass cullets or cause swelling, thereby deteriorating the quality and strength of the sintered product. As a method of molding glass cullet without using the sintering method, a technique using a resin instead of clay has also been proposed, but the problem is that the resin is expensive and deteriorates due to ultraviolet rays, so its life is short and there is a limit to its use. There is. Also,
The recycling rate of glass cullet is 60% or more at present, and a new recycling method is required. Of the glass bottles, wine bottles, in particular, have various colors and are considered to be most difficult to reuse, and the development of such reuse is an important issue.

However, since these are unstable in components, it is difficult to produce a uniform product. Contains many heavy metals. Therefore, with the aim of reducing the volume and sealing heavy metals for sewage sludge, and avoiding the generation of dioxin during incineration of municipal waste, there is an increasing trend to melt them and turn them into slag. The production of sewage sludge and municipal waste melting slag produced by gasification is steadily increasing. Further, in a blast furnace such as an ironworks, steel slag is generated as an impurity. Therefore, development of a method for effectively using these slags is required.

However, since a large amount of chips is generated during mining, development of new applications is desired. In addition, development of uses of crystallized incineration ash and pottery waste is desired.

他、セラミックの屑を含む。[0024] The present inventors have found that those which are expected to be developed for effective use, such as sewage sludge slag, municipal waste melting slag, iron and steel slag, waste incineration ash crystallite, and anti-fire stone, have a softening temperature lower than that of glass cullet. It was decided to use this as a dispersant, focusing on the fact that pottery waste, which is highly vitreous and is expected to be similarly developed for effective use, has a higher softening temperature than glass cullet. . When using anti-firestone as a dispersing material, it is desirable to use the chips, so-called anti-firestone chips, from the viewpoint of effective utilization of resources. Pottery waste includes ceramic waste in addition to normal ceramic waste.

て焼結体全体としての焼結性は向上する。In the method for producing a sintered body according to the present invention, since the sintering step is performed at a lower temperature than in the case of the above-described clay, the energy consumption is low and the amount of CO 2 emitted is reduced. Although the glass cullets soften and fuse together,
Since the dispersant does not melt at a temperature of about 1000 ° C., the dispersant plays a role of releasing air bubbles inside the glass cullet or between the glass cullets, improving the quality and strength of the sintered body, and improving the quality of the sintered body as a vitreous material. In particular, when the glass cullet is used, the glass cullet and the dispersing material are appropriately fused to improve the sinterability of the whole sintered body.

In the sintering step, the mixture may be vibrated to the extent that the mixture is not separated for the purpose of discharging air bubbles in the mixture.

Since it is used in place of clay or a resin which is expensive and deteriorates due to ultraviolet rays, a highly durable sintered body can be provided while reducing the load on the environment.

Here, as a glass bottle that is difficult to recycle, wine bottles that are colored in various shades are particularly problematic. By using the glass cullet of such a wine bottle, it is possible to effectively use a wine bottle that is difficult to recycle as a resource. The color of the sintered body can be diversified. In addition, sewage sludge slag, municipal waste melting slag, steel slag, garbage incineration ash crystal, and anti-firestone are gray to black,
