The present invention relates to a method for producing a fixed and supported water-absorbing composite.

問題があった。Examples of these water-absorbing polymers include polyacrylate cross-linked products, starch-acrylate graft cross-linked products, polyvinyl alcohol-modified cross-linked products, and maleic acid copolymer cross-linked products, but depending on the purpose of use, they may have a deodorizing effect. In some cases, it is desirable to have a However, since the polymer itself has little deodorizing effect, methods of adding activated carbon or the like to impart a deodorizing effect have been considered. However, as a method of blending water-insoluble fine particles such as activated carbon with a water-absorbing polymer, for example, JP-A-56-133028 and JP-A-59-38271 disclose methods of adding water-absorbing polymer powder and water-insoluble fine particles to a car. The only methods disclosed are methods such as mixing powdered water or adding mixed condensate to the water. In such a composite, the water-absorbing polymer powder and the water-insoluble fine particles are simply physically mixed, or in a state close to that, and furthermore, the mixed state is non-uniform, so the water-absorbing polymer powder and the water-insoluble fine particles are mixed. There were disadvantages in that the expression of effects was uncertain and insufficient, and the water-insoluble fine particles easily separated during transportation and storage. Furthermore, since the water-insoluble fine particles are handled in powder form, the working environment is seriously degraded by the dust, which poses a non-negligible problem in terms of occupational health.

ものでも、いずれでも使用でき、特に限定されない。Examples of such water-absorbing polymers include, for example, in addition to the above-mentioned crosslinked polyacrylates, hydrolysates of starch-acrylonitrile graft copolymers (Japanese Patent Publication No. 49-4339

であるし、しかも十分な効果が得られない場合もある。If the particle size of the above-mentioned water-insoluble substance is too large, it is preferable to crush it into fine particles before use. If it is too large, it is necessary to increase the amount added in order to obtain a sufficient dispersion state, which is uneconomical, and furthermore, sufficient effects may not be obtained.

い。On the other hand, if the fine particles have an appropriate size and shape, they can be well entangled with the water-absorbing polymer surface layer that is swollen by the water supplied together with the fine particles, and can be firmly attached. In order to obtain the various effects mentioned above, the fine particles are usually 50 μm or less, preferably 10 μm or less.

見合った効果の向上がＵめられ難くなるからである。さ
らに好ましくは０．１〜５重量部の範囲である。In the present invention, the amount of water-insoluble fine particles can vary widely, but is usually preferably 0.01 to 10 parts by weight per 100 parts by weight of the water-absorbing polymer powder. If the amount is less than 0.01 part by weight, the effect of adding water-insoluble fine particles may not be observed, and if the amount exceeds 10 parts by weight, the probability that water-insoluble fine particles will adhere to each other increases, and the effect commensurate with the amount added. This is because it becomes difficult to appreciate the improvement in performance. More preferably, it is in the range of 0.1 to 5 parts by weight.

合は水不溶性微粒子を乾燥させる工程と、乾燥させたも
のを粉砕する工程を省略することができ経済的である。In carrying out the present invention, the water-insoluble fine particles are used as an aqueous dispersion. The aqueous dispersion herein refers to a dispersion in which the water-insoluble fine particles are uniformly dispersed in water, and has fluidity. In a preferred embodiment, the upper limit of the viscosity is 10,000 cps (25° C.), and although a low viscosity does not pose a problem in the present invention, it is possible to use one having a viscosity substantially comparable to that of water. For example, a slurry, a suspension, an emulsion, and the like are also included in the aqueous dispersion in the present invention. Furthermore, when the water-insoluble fine particles are produced in the form of an aqueous dispersion, they can be used as they are without drying or in a somewhat concentrated state. Particularly in this case, the process of drying the water-insoluble fine particles and the process of pulverizing the dried particles can be omitted, which is economical.

エネルギーコストの上昇を招く結果となる。The amount of water used to prepare the aqueous dispersion can vary over a wide range, but it is usually preferably in the range of 1 to 30 parts per 100 parts by weight (hereinafter referred to as "parts") of the water-absorbing polymer powder. By adding water, the surface layer of the water-absorbing polymer swells and becomes in a state where it partially embraces the fine particles that are supplied at the same time as the water, making it possible to firmly support them. If the amount used is less than 1 part, the water-insoluble fine particles may not be supported sufficiently on the water-absorbing polymer powder, and if more than 30 parts are used, no improvement in effectiveness can be expected, and the energy cost during drying may be increased. This results in an increase in
吸水性ポリマー粉末と水分散液とを混合する装置として

適に使用できる混合装置として、例えば高速回転パドル
型混合機を挙げることができる。As a device for mixing the water-absorbing polymer powder and the aqueous dispersion, any mixing device well-known to those skilled in the art can be used without limitation, and a suitable example of a mixing device that can be used is a high-speed rotating paddle type mixer.

ることもできる。To describe a specific embodiment of carrying out the present invention using such a mixing device, for example, a water-absorbing polymer is placed into a cylindrical container in which the paddle of the high-speed rotating paddle type mixer is rotating at high speed. A typical example is a method in which the powder and the aqueous dispersion are continuously or intermittently supplied, and the mixture is continuously or intermittently discharged from the container. At this time, the degree of mixing can be freely controlled by adjusting the supply amount and discharge amount.

The drying method is not particularly limited, and any method may be used as long as it does not inhibit the functions of the water-absorbing polymer and water-insoluble fine particles.
