同様の手段で施工することを可能とした。Traditionally, cellulose fibers such as paper, paper products, and pulp exhibit excellent heat insulation, sound absorption, and sound insulation properties, so these fibers can be used alone or with flame-retardant, mold-proof, and insect-proof treatments to build buildings. It has been injected into spaces such as walls, under floors, and attic areas to provide insulation. These methods are generally called blowing methods or blowing methods. In addition, as a method for forming a molded body from chip-like materials such as cellulose fibers, an adhesive is applied to paper such as waste paper and crushed paper products by applying a conventionally known manufacturing method for glass wool mats and fiberboards. After that, it is easily possible to spread and laminate the material to form a plate or mat. [Problems to be Solved by the Invention] The conventional techniques described above have the following problems. In other words, the former construction method has the advantage that it can be constructed regardless of the shape of the building's space, and does not create gaps between columns, studs, edges, etc. in the space, but Compared to the case of installing sheet-shaped insulation materials, there are drawbacks such as a lack of uniformity in product quality due to on-site construction constraints, and poor workability such as generation of dust and relatively long work time. . In addition, water-based adhesives are often used in combination to improve the adhesion of cellulose fibers, but in this case, the moisture in the adhesive cannot be removed, which promotes the formation of dew condensation. It was also the cause. In the latter method of forming a mat, it is difficult to simultaneously satisfy the mechanical strength and heat insulation/sound insulation properties of the product, and it also has the disadvantage that a product with stable quality cannot be obtained. The present application has been made in view of the problems of the prior art, and its purpose is to provide something that can do the following. That is, the present invention aims to make it possible to form a plate-like or mat-like heat insulating material in advance without losing the characteristics of cellulose fibers, and to bring about great industrial effects. [Means for Solving the Problems] In order to solve the above-mentioned problems, the inventor of the present invention has conducted a detailed study, and as a result, the quality of the product obtained by the shape and composition of the paper and paper product pulverized material to be used has been determined. The present invention was achieved based on the discovery that this is largely related to That is, 1 the present invention applies a water-based emulsion type adhesive or pressure-sensitive adhesive at a predetermined ratio to a fibrous material obtained by crushing paper and paper products, spreads and laminates the adhesive, and then dries and removes excess water. A mat-like molded product is formed by roughly crushing the paper and paper products used as raw materials and using large paper pieces of 10 mm or less and 3 m or more in size that retain the paper shape and a 1Ilfil sieve. The first basic feature is that it is a mixture of fine cellulose fibers that can pass through it. That is, in the present invention, the ratio of the fine fiber portion was adjusted to be 300 to 1000 parts by weight to 100 parts by weight of the waste paper piece portion. If the paper dust item is composed only of fine fibers of less than 1 am, it will not be possible to obtain a product with excellent mechanical strength compared to the amount of adhesive, and if too much adhesive is used, the product density will be relatively low. increases, resulting in a loss of insulation. On the other hand, if it is made up of only several pieces of broken paper, the mechanical strength is high, but the density of the product is also large, and the internal voids formed between the pieces of paper are also large, so the air permeation resistance is reduced. , this also results in loss of heat insulation properties. In contrast, the structure of the present invention forms a structure in which coarse paper pieces are dispersed in a matrix of fine fibers. In addition, most of these coarse pieces of paper are bonded through fine fibers, but some of them are bonded between the paper pieces. Therefore, the coarse paper pieces effectively share the mechanical strength, and a product with excellent mechanical strength can be obtained with a relatively small amount of adhesive compared to the case of using only fine fibers. Furthermore, the large-volume voids that occur when using a single piece of coarse paper are filled with fine fibers, and are transformed into more finely divided voids. As a result, air permeation resistance increases, and the presence of fine fibers also reduces product density, which, combined with the reduced amount of adhesive used, makes it possible to create a product with excellent heat and sound insulation properties. . Naturally, if the shape and composition of the paper composition deviate from this range, the results will approach those obtained when each is used alone, and it will not be a practical product. [Effect] This will be explained along with the effects. [Embodiments of the Invention] Examples will be described with reference to the drawings. Used paper whose water content has been adjusted to about 10% is pulverized so that fine fibers with a size of 11 or less are 300 to 1000 parts by weight per 100 parts by weight of coarse paper pieces with a size of 11 or more. This waste paper pulverized preparation was processed using a blower at a rate of 100 kg per hour.
Furthermore, the solid content concentration in this discharged material is 2.
An aqueous acrylic emulsion type adhesive adjusted to 5% is sprayed using a spray gun at a rate of 40 kg per hour, and the adhesive is dotted onto the waste paper pulverized preparation by mixing them under an air stream. The crushed waste paper coated with adhesive is immediately stacked as is. It is desirable that the blending amount of this adhesive is in the range of 5 to 15% based on the crushed waste paper, and the solid content concentration of the adhesive is in the range of 25 to 50%. This is because if the amount of adhesive is small, the required mechanical strength cannot be obtained, and if it is excessive, the product density increases and the heat insulation properties decrease. If the solid content concentration of the adhesive is low, mixing of the adhesive and fibers will be hindered, and if it is high, the moisture content of the product will increase, which will interfere with the subsequent drying operation. Further, as in the case where the amount of adhesive is large, the density of the product increases. In this way, by appropriately setting the blending amount of the adhesive and the solid content concentration of the adhesive, it is possible to adjust the moisture content of the laminate and the product density. Further, if necessary, the density can be adjusted by applying a compression operation after lamination. Next, the laminate is heated or vented to absorb moisture.
It is dried so that it becomes 0% or less. By controlling the moisture content to 20% or less, the adhesive layer between the paper pieces and the fibers becomes strong, and there is an effect that the shape does not collapse during normal handling operations performed during construction. If the laminate has already been finished to the same thickness as the required product, it can be used as a product. In addition, if there are multiple layers, after drying, the product is cut out to a predetermined thickness. Typical properties of the product thus obtained are as follows. Moisture: 15% Density: 0.04 Thermal conductivity: 0.034 As a variation of the present invention, a part or all of one large piece of paper may be replaced with another similarly shaped material, for example,
It is possible to replace it with natural vegetable fibers such as rice straw, bagasse, hemp, rush, and rice grains, threads made of natural and chemical fibers, pieces of cloth, or mineral fibers such as glass fibers and rock wool. In these cases, micro-pressed cellulose fibers provide insulation and
Since the sound insulation properties are shared, an effect similar to that obtained using coarse paper pieces can be obtained, but the mechanical strength is further improved. Moreover, by carrying out this lamination operation on plastic sheets, cloth, plywood, and metal plates, it is possible to obtain products integrated with these. Furthermore, as a variation of this, it is possible to manufacture a sandwich structure or one in which these materials are placed in the middle layer of a cellulosic insulation material. Furthermore, after the lamination operation, it is also possible to apply a synthetic resin to the surface portion of the cellulose-based heat insulating material and harden it to form a reinforcing coating. By these means, it is possible to obtain a product with even better mechanical strength. Furthermore, the crushed waste paper can be treated in advance with fireproofing, insectproofing, and moldproofing, and in this case, these properties are imparted to the resulting product, which has great practical effects. Furthermore, by pre-water-repelling the crushed waste paper, the penetration of applied adhesive droplets into the fibers is suppressed, making it possible to bind fibers together in dots with a smaller amount of adhesive. This makes it possible to further improve the heat insulation properties and physical properties. [Effects of the Invention] Since the present invention is configured as described above, it produces the following effects. The cellulose-based heat insulating material of the present invention has strong strength and thermal properties by forming a mixture of coarse paper pieces obtained by crushing paper and paper products and fine fibrous material into a mat shape using an adhesive. These two elements are assigned their respective functions, and the material has a well-balanced combination of these functions. As a result, we have been able to supply cellulose-based insulation materials as mat-like industrial products of uniform quality, and have realized rationalization and simplification of insulation construction. In other words, it has become possible to construct a cellulose-based heat insulating material that is functionally superior to heat insulating materials such as glass wool and rock wool using the same method.
