Description

The method put to sheets of paper both sides of Polyethylene-rezin film together and manufactured goods}

The present invention relates to a bonded processing paper in which pulp is pressed onto both sides of a film with respect to a film fabric and a pulp fabric having an undetermined length, and a method of manufacturing the same, wherein the fabric of the film is a large amount of lime (CaCO3) added thereto. The fabric of the finished polyethylene-rezin film product, and the pulp fabric is made of pulp products, which are classified as foil or pure white roll paper having a basis weight of 0.05 mm. By the above description, the present invention is based on the manufacturing method using the joining processing technology, which is based on [Patent Publication 998-2440], for example, the case of the window paper manufacturing method, the contents of the synthetic resin on both sides of the transparent synthetic resin plate It discloses about the manufacturing method of the window paper formed by apply | coating a paste and attaching and pressing Hanji on both surfaces.

Further, in the case of a moisture-proof paper that is easy to recycle according to [Patent No. 98-2441], for example, the content contains a copolymer of styrene-maleic anhydride copolymer or styrene-maleic acid derivative between polyolefine on paper. The process of introducing an alkali-soluble strata is disclosed.

In addition, there are many products that use the bonding processing technology, for example, various corrugated cardboard or silver foil. According to the already known contents, there are various types and various uses of the bonded processing paper. In general, the bonded processing paper is made of polarized paper, glassine paper, white paper, kraft paper, paper, such as paper, plastic film, cellophane, vinyl chloride, polyethylene and polypropylene, and aluminum foil. The use of the bonded processing paper is a case for reinforcing impact resistance and strength, such as corrugated paper bonded to each other to increase the thickness and strength, and the products processed by bonding other materials such as silver foil are mostly moisture resistant, resistant to (耐 脂 性) To increase shading, it can be easily found in everyday life. As described above, the use of the bonded processing paper is various, but the motivation of the present invention is a non-material that generates filth or odor from medicines or various solutes or solutions on the bed sheets and clothes that they use for emergency or surgical patients in hospitals. The idea of dilution papers was to think that it would be effective to remove odors and maintain cleanliness when treating activated garbage. It also comes from the idea that if there is such a product, the product itself has an environment-friendly property, there will be more ideal utility.

The invention of the dilution paper has been studied in the field of bonding processing in the above-mentioned point, and the environment-friendly, biodegradable material that was not previously thought, that is, the film containing lime between The present invention has been invented a method of producing a new product by heating and pressing pulp having water-absorption and dispersibility.

The object of the present invention is as described above.

On the other hand, the dilution paper size of the present inventors is not standardized and its design is also not considered the taste of the consumer is also highlighted, the circumferential surface of the upper roller drawn in [Fig. Embossed convex is applied to the upper surface of the dilution paper produced by the process by engraving. However, from a technical point of view, the design should be considered elaborate and scientific, and the developmental study on functionality as a medical or oriental use will be an urgent task for the present invention in pulp pressed on both sides of the film. For example, by adding an appropriate fragrance, it is possible to improve the sense of smell in use, or it can be treated with herbal treatment to promote health and to have clean functionality of the product.

As an example, in order to eliminate the stiffness and stimulation of the dilution paper of the present invention, and to avoid the burden on the environment during the waste disposal process, alkaline lime is added to the thermoplastic resin and the basis weight is 0.03 mm. It is to use the film product adjusted to.

Hereinafter, described in detail by the accompanying drawings as follows.

1 is a process chart showing a series of process for producing a dilution paper. This is extruded in a state where the film fabric and the pulp fabric are laminated between the upper roller in a high temperature state and the corresponding lower roller. The process is the same as that of a known joining process. Lime-added polyethylene resin film is a thermoplastic resin that is dissolved at about 120 ~ 140 ℃ but the present invention is dissolved in the process of instantaneous extrusion at the optimum temperature of about 200 ~ 250 ℃ and at the same time cooled in the air to flow out of the paper It does not cause the problem of changing its shape or tearing, because the pulp protects both sides of the film, and also because the lime contained in polyethylene resin blocks the flow of the melted resin. It is also. The main reason why lime should be added is to develop environmentally friendly products, but to eliminate the concern that the products produced during the process will be spoiled. In general, lime has a variety of uses because its properties are contrary to acidity, and it is mainly used for lime fertilizer, acid soil improver, desiccant to moisture collecting agent, lime mortar, mixed mortar, mixed cement, raw materials for civil construction materials and bleach. Closely useful for carbides, lime nitrogen, etc. As such, the thermoplastic resin, ie, the polyethylene resin film, as a finished product containing lime (CaCO3), which is useful for its use, has a clear chemical property. Thus, the pulp is pressed and bonded on both sides of the film. It is useful by heat treatment.

In the foregoing, the manufacturing method for producing dilution paper has already been described in the field of bonding processing. The manufacturing method of the joining process is a matter already known in the foreign patent applications. Indeed, a French patent application No. 81.16574 describes a process for forming a laminate of cardboard, in which a thermoplastic material made of pure or scrap material and made of particles is sandwiched between two sheets of cardboard, which is then Its heating, compression, molding, cooling, and length cutting are the main points. In addition, according to the desire of the processor, a plurality of thermoplastic material layers and a plurality of cardboard layers are alternately arranged between the upper and lower layers of the cardboard to complete the finished product. Varying the thickness and imparting the appropriate mechanical properties to it, the superimposed layers of the cardboard and thermoplastic material together undergo a heating step and a compression step so that the dissolved thermoplastic material is completely and accurately in each of those layers and in the two outer cardboard layers It is known to be attached.

In addition, the following facts are known domestically in Patent Application No. 89-8773. It relates here to the continuous manufacture of elongated products, such as shapes or plates, which have a core of thermoplastic material which may contain or be free of fillers and are protected by at least one flexible sheet of material. It is explicit. In addition, with respect to the manufacture of a wide variety of siblings and plates having a core of thermoplastic material, each cross section containing or not containing a filler and having a core of thermoplastic material sandwiched between an old flexible film sheet such as paper, cardboard or polyethylene film. Are facts known from a number of recent techniques. However, if the present invention is different from other manufacturing methods, even though there is no difference in the manufacturing process itself as an area of the joining process, the embodiment ignores the first material and complicated process of the finished product. It is only extrusion that relies on instantaneous high temperature compression. Of course, this includes cutting after completion, and the configuration of the present invention is an example that has not been attempted in the prior art, two pulp (0.05mm foil or pure white roll paper) and one film (lime so-called CaCO3) The finished product of the processed polyethylene resin film), and the pulp is laminated on both sides of the film, and the laminated paper is made of two end rollers that provide heat and pattern when extruded, and the diluted paper produced by extrusion. (A polyethylene resin in which lime is added as a component of a material, i.e., a finished product in which pulp is pressed on both sides and embossed on the surface as a filler). Referring to Figure 4 is a cross-sectional view of the dilution paper, the upper and lower parts correspond to the pulp, and the part appearing in the middle is between the instantaneous melting and quenching while passing between the rollers dissipating heat of about 200 ~ 250 ℃ It turns out that the film as a product in which fusion was performed is shown.

The overall composition of the dilution paper is as follows. First, as shown in FIG. 2, the upper roller is the space between the two rollers in the embodiment, so that three heater rods are inserted so that the heat transfer is maintained at about 200 ° to about 250 ° C. through both terminals of the heater rod. A sensor that detects can usually maintain about 250 ° C at the reference temperature. Also, in this process, the rotation speed of the roller is also related. If the roller is stopped, the lamination should not be sandwiched between the rollers. Due to the nature of the paper, there is room for the film to dissolve or the pulp to be burned, which means that the paper is extruded between the rollers when there is a rotational speed of the roller.

In addition, the embossing method is already known in the present invention as regards the part of the surface of the dilution paper, which is a finished product by putting a pattern on the roller, and in the present invention, the surface of the dilution paper is embossed on the surface of the lower roller by the rotation of the patterned upper roller. That is, the embossing method is useful by protruding a pattern of regular intervals on the surface of the upper roller as shown in FIG. 3 and continuing to rotate until the surface of the compressed high density pulp portion of the lower roller is raised to the same depth as the upper end. Extrusion of the dilution paper by embossing in an embodiment to emboss the dilution paper is useful in consideration of the design of the finished product and the uniformly or evenly or precisely fused with each other.

As described above, the present invention is a method of compressing two kinds of fabrics by simple reason and the actual effect of the dilution paper completed through the process is as follows.

The dilution paper produced by the present invention includes double-sided water-absorption and dispersibility, and waterproofness is useful. In practical terms, its usefulness relates to objects that are to be protected from the effects of undesired solutions, solutes, and various kinds of dirt in the real world. In a broad sense, in the narrow sense of clothing, textiles or flooring, or dining table, In addition, the usefulness of dilution paper from dirt, drugs, and blood generated during surgery on bed sheets used for medical use in hospitals, medical tool display boxes on operating tables, or clothing of patients, etc. results in a clean image. Efforts to completely remove traces of previous procedures will be an important task for any hospital. The two-sided water-absorption and dispersibility of the dilution paper also applies to odors, which is important for hospitals where cleanliness is important in that penetration and absorption from the object can be prevented by the film in the composition of the product and at the same time it can block the diffusion. Its usefulness is valid.

As described above, the present invention is intended to give the effective effect to the portion of the dilution paper produced by the present invention biodegradable bonding paper by using the film product using the lime, which is an environmentally friendly material as the material.
