Description of the Related Art Conventionally, for the oil absorption treatment of these oils, cotton-like, fibrous, or blanket-like oil-absorbing materials made of mere natural paper pulp, waste paper, recycled paper pulp or non-woven fabric have been used. That is, as a conventional technique in which a water repellent material is not used, a non-woven fabric made of general chemical fibers, natural paper pulp fibers, opened fibers such as used paper, etc. have been used.

があった。Therefore, although the absorption of water and the absorption of oil occur at the same time, or generally due to the manufacturing process, the fibers themselves are often hydrophilic, and water is absorbed preferentially. The result was that oil absorption was hindered. These oil-absorbing materials adsorbed oil and at the same time adsorbed water in the vicinity of the oil. Therefore, the oil absorption efficiency is poor,
In addition, since the water absorbed by the capillary phenomenon wets the surface of the pulp fiber, the apparent specific gravity of the oil-absorbing paper to be composed becomes 1 or more, so that there is a problem that the material after oil-absorption processing settles in water. It was

理済材料の回収が容易にすることができる。The object of the present invention is to treat water in a water-repellent manner by treating the fibers of paper pulp with a water-repellent treatment or by mainly using paper pulp that has been subjected to waterproofing and water-repellent finishing to be opened like cotton. In the case of absorbing mixed oil and oil floating on water, it is water-repellent, so that water is not adsorbed, and a property of adsorbing only oil by a capillary phenomenon is imparted. Further, after adsorbing oil, it has spongy coagulation, floats with a clear boundary with water, and does not settle in water. When the oil is not adsorbed, the fibers themselves are hydrophobic and the surface tension with water is so large that they do not get wet so that there is no sedimentation in the water. , Shows a change in color and facilitates the determination of whether or not the oil absorption ability is possible. Further, since the oil-absorption-treated material of the waste oil floating on the water does not settle, the treated material can be easily collected.

As the water repellent material, a solution of oils and fats, cellulose ester, vinyl resin, silicone resin or the like is used. These water repellent materials are thoroughly mixed with a high speed mixer to coat the fibers of the paper pulp uniformly. This treatment ensures that the surface tension of the fibers with respect to water is extremely high. In addition, these water repellent materials are also materials that are lipophilic or partially combined with oil to form a highly viscous gel.

Need to let. If it is less than 1%, the water absorption and the oil absorption occur at the same time, and the oil absorption capacity decreases, and it becomes impossible to maintain the state that the material after absorbing oil floats on water, especially when it floats on water. When the waste oil is subjected to the oil absorption treatment, sedimentation of the material is observed, which makes it difficult to recover the treated material.

Therefore, the absorption of water and the absorption of oil occur at the same time, or generally due to the manufacturing process, but the fibers themselves are often hydrophilic, and the absorption of oil is hindered because water is preferentially absorbed.

状態が良好である。When the oil is adsorbed, the oil adsorbability is improved by the amount that water is not adsorbed as compared with the conventional product. Since it repels water and adsorbs only oil, not only is oil adsorbed quickly in the removal process of oil that floats above the sea or above water, but also because only oil is adsorbed, oil up to the oil film at the interface with water It can be removed and a clear boundary with water can be created. Also, after adsorbing oil, it aggregates like sponge and does not settle in water. This can greatly streamline the work of removing oil that has flowed out to seawater, lake water, rivers, etc., and can clean the water quality, which will greatly contribute to the improvement of the environment. In addition, the material after the oil absorption treatment can be discarded as a general combustible material, and can be used as an auxiliary combustion material for combustion and can be used as an effective use of energy by separating and collecting. The state of combustion is good because it does not adsorb water.

As a comparison, a pulp containing no pulp is placed in a 300 cc beaker, 250 cc of tap water is poured, and 15 cc of machining waste oil is poured over the beaker and stirred, and then allowed to stand. Waste oil floats on the surface of the water. Then, each flocculent pulp was thrown into a 3g beaker, and the oil absorption state was compared and investigated. As a result, the pulp completely absorbed the waste oil in 10 seconds. The cotton after oil absorption was aggregated in a sponge-like manner and the boundary with water clearly appeared, and did not settle in water even after 100 hours had elapsed. Pulp absorbs water as well as waste oil, and it takes more than 60 seconds to absorb waste oil,
It was dispersed so that it would swell from the part that absorbed water, the interface with water was not clear after adsorption, and the position in water was not clear after standing for 24 hours, causing it to float or sink. The pulp absorbs both water and oil, and it takes 120 seconds or more to absorb the waste oil.
After hours, the position in the water was not clear, and it floated and sank. Moreover, although the recovery work was easy, the recovery work was not easy and the water quality was observed.

質の汚濁がみられた。[Example 2] As a cotton-like material, vinyl-coated water-repellent paper was used to crush the waste paper to be discarded, and contained 1% or more of cotton-like pulp opened and less than 1% of the same pulp. The oil-absorption conditions were compared and investigated in the same manner as in Example 1, using as the comparison those that did not contain the same pulp at all. As a result, the pulp completely absorbed the waste oil in 15 seconds. The cotton after oil absorption was aggregated in a sponge-like manner and the boundary with water clearly appeared, and did not settle in water even after 100 hours had elapsed. The pulp absorbs not only the waste oil but also water, and it takes more than 100 seconds to absorb the waste oil, and it disperses so as to swell from the part that absorbed the water. The position in the water is not clear,
It floated and sank. The pulp absorbs both water and oil, and it takes 120 seconds or more to absorb the waste oil. Like the pulp, it swells and disperses, and after 24 hours the position in the water is not clear, and it floats or sinks. . Or, the collection work was easy, but it was not so easy and the water quality was polluted.
