It is processed by the alkali method to produce waste paper pulp, which is cut with a beater (refiner) or refiner (refiner), crushed, fibrillated and dispersed in water, and then collected by filtration with a paper machine and dried. It is produced as a thin leaf, or a plurality of sheets are laminated in an undried state, and so-called piling is performed to produce a paperboard having a desired thickness. Further, with regard to Japanese paper, bast is cooked with a sulfate to produce bast pulp, which is prepared with a handrail or a paper machine.

体の木材の使用量から比べると極僅かである。[0003] In recent years, due to the deforestation of wood used as a raw material for pulp, humus has flowed out to roughen the mountain surface, causing serious environmental damage such as floods. Therefore, although used paper and corrugated paper are collected, the paper is produced as it is from the processed waste paper pulp, or it is mixed with wood pulp to save wood resources, but the amount is It is extremely small compared to the total amount of wood used.

混入する時期に応じて次の三通りが可能である。In order to solve the above-mentioned problems, the present invention makes a crushed rice husk crushed to a predetermined particle size under pressure and heating coexist with other pulp, and uses a conventional papermaking method. A paper and a paper product containing the produced rice husk as a material were constructed. Incidentally, as a known paper-making method, there are a wet method and a dry method, wherein the wet method is a cutting step of crushing, crushing, fibrillating and dispersing in water, and a papermaking step of collecting by filtration and drying. The dry method is a method for mechanically, aerodynamically or electrostatically dispersing, settling, sucking or adhering pulp fibers to prepare. The former is an ordinary paper manufacturing method, and the latter is a non-woven cloth, flocking or other manufacturing method. The following three methods are possible depending on the time when the crushed rice husks are mixed with pulp or an intermediate during the processing thereof.

The paperboard of Sano is made. This includes
It also includes cooking only the crushed rice husk and mixing it with the disintegrated recovered paper to produce pulp.

When rice husk pulp obtained by digesting or cooking with pulp raw materials is mixed with waste paper pulp, paper and paper products can be obtained from the composite pulp increased in amount by the known papermaking method. Further, if the crushed rice husks are mixed with the pulp and produced by a known papermaking method, the crushed rice husks are carried between the fibers by the pulp to fill the gaps between them, and the density is high and the bending strength is strongly modified. Paper and paper products are obtained. Similarly, the crushed rice husks are uniformly adhered and mixed with the intermediate being processed in the papermaking step through the pulp conditioning step, so that the crushed rice husks are directly embedded in the surface layer portion, and the surface is provided with a non-slip action. Paper and paper products are obtained.

It is a so-called compressed / crushed rice husk that has been crushed under pressure and heat.The tough cell structure is broken, lignin is halved compared to normal rice husk, and the proportion of cellulose components is relatively increased. Therefore, it can be disintegrated by cooking or other known pulp production methods. In addition, since the crushed rice husks or rice husk pulp essentially contain natural cellulose as a main component, hydrogen bonds are generated between the natural cellulose fibers constituting the ordinary pulp, and the fibers are entangled with each other and strongly bonded to each other.

Needle-shaped crystals of rice husks remain and the cell structure is stronger than pulp, mechanically grind with a grinder, or heat and pressurize in a short time, explosive treatment by rapid decompression, etc.
Alternatively, it chemically interferes with the disaggregation of fibers by a digestion treatment with a sulfate or the like. Therefore, the crushed rice husk used in the present invention is

してパルプを製造する。That is, first, raw wood such as conifers and hardwoods is shredded to produce wood chips, which are digested with alkali. Alkali is lost in this cooking operation, which is supplemented with sodium sulfate. Compensation for this lost alkali with sodium sulphate is based on the following principle: sodium sulphate produces sodium sulphide when ignited with carbon (in the case of pulp the organics present in the cooking effluent).
For example, Na 2 SO 4 + 4C = Na 2 S + 4CO, and sodium sulfide forms an alkali when dissolved in water. Na 2 S + H 2 O = NaOH + NaSH That is, when the cooking waste liquor is concentrated and further ashed and melted, a required amount of sodium sulfate is added to produce sodium sulfide. The melt thus obtained is mainly composed of Na 2 CO 3 (65 to 70%), and then contains a large amount of Na 2 S (about 20%). This is dissolved in water and lime is added to causticize. , Used for preparing cooking liquor. Then, after performing the above-mentioned digestion treatment, unnecessary components are removed, and bleaching treatment is carried out appropriately to produce pulp.

Further, with regard to Japanese paper, bast is collected from raw materials such as Mitsumata and Kozo, and similarly treated with an alkali (lime, caustic soda, sodium carbonate, etc.) method to produce pulp.

Further, in the papermaking step, the pulp water is filtered and collected by a net to form a thin leaf and dried. This papermaking process is automatically performed on the Fourdrinier paper machine,
A roll-shaped base paper is obtained.

It produces composite pulp. In this case, the crushed rice husk becomes the basic structural material of paper and paper products. At the mixing time B, wood pulp, bast pulp or waste paper pulp is mixed with crushed rice husk, beaten with a refiner, and dispersed in water. In this case, the crushed rice husk does not become the basic structural material of paper and paper products, but is filled and supported between natural cellulose fibers which are structural materials, and becomes paper and paper products having high density and bending strength. Then, at the mixing time C, it is collected by filtration in the papermaking process, uniformly sprayed or sprayed on the surface of the thin leaf-shaped intermediate material containing a sufficient amount of water, and then compressed by a dandy roll. In this case, the crushed rice husks are embedded in the surface layer to form a paper or a paper product, and the crushed rice husks have their own characteristics and exhibit the anti-slip and matting effects of the paper and the paper products.

For example, about 5% by weight is preferable for Japanese paper used for shoji paper, and wallpaper and the like can be mixed up to about 50% by weight. It is preferable that the crushed rice husk is mixed in an amount of 5 to 10% by weight with the base paper for the liner 1 of the corrugated board as shown in FIG. 3, and 30 to 50% by weight is mixed with the base paper for the center 2.

The wet method has been the mainstream since ancient times, but there are many problems in terms of pollution, so this dry method will become more important in the future. Since the crushed rice husk can be finely pulverized up to about 400 mesh, it has excellent applicability even in the dry method.

Since it is made by the paper manufacturing method of No. 1, the amount of pulp used can be saved without significantly lowering the overall paper quality,
As a result, effective utilization of forest resources can be achieved and paper and paper products can be modified.

By doing so, since it is strongly supported by the hydrogen bond between the natural cellulose fibers of the pulp, it is possible to improve the density and bending strength or shear strength of the paper and the paper product. Similarly, the crushed rice husks are uniformly adhered to and mixed with the intermediates being processed in the papermaking process through the pulp preparation process, so that the crushed rice husks can be embedded as they are in the surface layer portion to provide a non-slip action. In particular, when a corrugated cardboard base paper is used, when a large number of corrugated cardboard boxes manufactured by the corrugated board are stacked, the contact surfaces of the corrugated boxes are less likely to slip and collapse even if vibration or lateral shake occurs.
