Description

Detailed Description of the Invention

This invention applies to polyethylene, polypropylene, PET,
New PPT, PEA, OPP resin and P of industrial waste
ET, PPT, PEA resin as a raw material, and a resin paste obtained by dissolving it by adding a mince mineral powder, a pigment, and adding a 30% phenol aqueous solution or another phenol mixed solution as a solvent to fabric fibers, fiber paper or other fibers. Using a resin film made by applying it to the quality, drying and heating and melting it as a substitute for paper, as a substitute for memo paper boards and notebooks, and as wallpaper, write with printing ink, ballpoint pen ink, magic ink Not only resin film processed products that can be easily wiped off with a sweeper containing an eraser or a surfactant, but also waterproof and mildewproof wallpaper and tile paper, peelable water surface processing, tipak and paper bags. By making a resin fill that is characterized by processing, erasable printing ink erasable and waterproof, antibacterial, and peelable that enables effective reuse of industrial waste and recycling of natural wood resources. Is according contents sexual resin processed article. In general, letters and pictures scribbled on the wall of a residential condominium may damage the privacy of people, and it is necessary to erase them, but it was difficult to remove them easily. Further, when it is necessary to erase the secret text of the copy paper or the printing paper, the amount of dust increases because the paper is cut or crushed by a cutter, and it is often difficult to reproduce it. Also, telephone memo paper, notebook paper, school paper, painting paper,
On blackboards, a complicated process is required to recycle what was written or printed with an oil-based ballpoint pen, magic ink or printing ink, and it is not possible to erase with a simple rubber eraser or surfactant. Since it cannot be done, it consumes a lot of wasted paper, leading to the depletion of wood resources and becoming a social problem. On the other hand, the current situation is that waste is treated at a high cost. Even when considering this memo paper and notebook for students, the reason why oil-based ballpoint pens are often used is that pencils are vulnerable to friction and easily erased. However, this oil-based ink cannot be erased with an eraser and cannot be erased with a surfactant, so it was necessary to replace the paper with a blank sheet for recording. In the case of wrapping paper and cardboard, food stores such as supermarkets are increasing the number of cases of direct sales, and the display at the time of arrival and delivery affects the freshness of food, and sometimes it is wasteful to discard fresh food from time to time. Written packaging labels, tapes, or the entire surface of corrugated cardboard can be pressed with a polypropylene powder film or heat-sealed, or a bonded resin film can be written with magic ink and the date can be easily displayed. It is useful because it can display the store opening order and can be reused and collected many times. In particular, when it is used as a substitute for the outer kraft paper for corrugated board, the adhesiveness is improved when the amount of the mining mineral powder mixed with the polypropylene resin is increased. Therefore,
A mixing amount of 30% or more is practical. A porous resin obtained by adding an inorganic salt powder such as limestone, gypsum powder, baking soda powder, salt, salt cake, urea, etc., and extracting with an acidic liquid can also obtain the same effect. In addition, PET resin, PPT resin, polyamide resin,
When applying a paste prepared by dissolving paraffin powder in a 30% aqueous solution of phenol solution on the wall surface and treating with hot air to form a film, graffiti is added as a surfactant solution, thinner solution, acetic acid ester, acetic acid, butyric acid ester. The resin film is not destroyed even when it is erased with an organic solvent such as acetone, benzene, alcohol, benzaldehyde, triethanol, amine acrylate, phenolcyclo, hexanone, or furan. It is also used as a bonding resin for the PET, PAT, PP and PE film resins, and is also used as a red ink paste applied to the film resin. in this case,
Heat treatment is performed with hot air of 180 to 300 ° C. to fuse them. The PP, PE, PET, and PPT resins have poor adhesion of general ink, but the aqueous liquid paste of the present invention is not only very stable as an ink paste liquid containing a pigment, but also has a long-term antifungal effect. Not only can it be mixed with polyamide resin, phenolic resin, and synthetic rubber, it can have various characteristic properties, but it is also useful as synthetic leather or wall cloth when applied to fiber cloth and heat treated. Trilaminated paper is used as notebook paper and copy paper as PET paper. In particular, when making this ink paste as a reprocessing treatment of PET and PPT, it is difficult to erase with alkyl benzene and sulfonate as a surfactant as a erasing agent useful for effective regeneration of industrial waste, but erasing is difficult. Surfactants consisting of long dodecyl petroleum plus phenol and long molecules of ethylene oxide are used. Also, a phenol triethanolamine solution is used. This surface-active agent can be easily erased by impregnating paper, cloth or sponge resin and wiping it off. As described above, P
P, hard PE film, PET, PPT resin, a coating of 10% to 50% of a mixture of mines ore powder, bentonite, zeolite, pumice powder, limestone powder, gypsum powder, etc. When using on notebook paper, memo paper, copy paper, you can easily erase with an eraser or surfactant sweeper as an eraser printed with oil-based ink, magic ink, printing ink, Recycling the amount reduces costs, saves resources, and helps eliminate privacy graffiti in used condominiums and homes. This resin coating is useful for erasing graffiti in elevators and toilets and erasing printing ink on copy paper, and is useful as an antifungal agent, so it is an industrially useful invention.
