Abstract

The present invention relates to a method for producing high-gloss, high-strength printing paper and fiber film made through roll coating at room temperature under normal pressure using an ultraviolet curable resin without pressing or heating rolled printed paper or fibers.

The coating method sprays UV-curable resin onto a winding machine for winding printed paper and film in a roll form, a pair of rollers and a horizontal roller while feeding at a constant speed, and at least one of the pair of rollers. It consists of a plurality of resin discharge holes that can be coated on paper and fibers, scrapers to collect the extra resin while maintaining a constant coating thickness, and after the resin is applied, the resin is applied to the surface protective film through a film winding machine The present invention relates to a method of manufacturing high gloss and high strength printing paper and fiber film obtained by wrapping a film on a surface of a paper and a fiber roll, partially drying it through a drying furnace, and then winding the film through a UV curing chamber equipped with an ultraviolet lamp.

Description

The method of high strength and high glossy printed paper / fiber by UV curing}

The present invention relates to a method of manufacturing high-strength, high-gloss printing paper and fibers that can be applied to architectural interior and exterior materials and floor decorative materials by protecting the surface of paper and fibers printed by various methods and giving high gloss, and more specifically, in the form of rolls. The present invention relates to a method for producing high-gloss, high-strength printing paper and fiber films made of rolled paper under normal pressure and atmospheric pressure using an ultraviolet curable resin without pressurized or heated printed paper or fibers.

Conventional paper and fiber coating methods apply a polyethylene film on the printed surface for strength and surface gloss, dissolve resins such as polystyrene in organic solvents, or cut hot melt resins at high temperature and apply them to the surface. Has come. However, the coating method according to the above method is uneconomical due to poor workability due to curing at room temperature, requires a certain curing time, and consequently the installation of additional equipment and loss of raw materials.

In general, coating with an organic solvent can obtain a high gloss product, but has a disadvantage of being environmentally harmful and flammable to humans due to organic substances discharged after use, and the method of aqueous coating is difficult to obtain a high gloss product, To this end, it can be solved by increasing the solid content of the water-based coating agent, but the viscosity increase and dispersibility are significantly lowered, resulting in poor workability and difficulty in uniform surface coating.

The present invention provides a high-strength, high-gloss printing paper and fiber that can be applied to interior and exterior materials and floor decorative materials by protecting the surface of the printed paper and fiber surface or veneer with a coating by UV-curable resin and giving a high gloss to solve the above problems. Or it relates to a method of manufacturing veneer, more specifically, high-gloss, high-strength printing paper and fibers or veneer made of rolled printed paper or fiber in the form of rolls using a UV-curable resin without pressing or heating at room temperature under normal pressure A method for producing a film.

The manufacturing method according to the present coating includes a winding machine for winding a rolled printed paper film, a pair of rollers for feeding and maintaining a horizontal level at a constant speed, and at least one of the pair of rollers, an ultraviolet curable resin. It consists of two or more resin discharge holes that can be sprayed onto the paper and fibers, and a scraper to collect the excess resin while maintaining a constant coating thickness. The resin is then applied to the recovery pump. It is supplied to the resin supply portion of the roller through. The surface protection film supplied through the film winding machine is wrapped on the roll surface of the resin coated paper and fibers, and partially dried through the drying furnace, and then passed through an ultraviolet curing chamber equipped with an ultraviolet lamp or a chamber for irradiating an electron beam. It is done by passing it and finally winding it. Surface protective film may be PET, PP, PVC, PE, OPP, NYLON film. Here, a pair of coating rollers are formed with a coating liquid discharge hole on both the upper and lower roller surfaces, and can be applied on one side and both sides, depending on the application, and then the one side and both sides can be wrapped by the surface protection film.

Hereinafter, the configuration and operation of the present invention in detail.

As the coating medium used in the present invention, a continuous paper and fiber roll type printed by various methods such as conventional heat, pressurization and sublimation transfer can be used.

As the ultraviolet curable resin used for coating, a resin containing a certain amount of an ultraviolet curable catalyst in thermosetting resins such as phenol, epoxy, urene, acrylic, melamine, polystyrene, and unsaturated polyester may be used. Depending on the wavelength range, the reaction rate and the reaction rate are different and generally catalysts of amines (primary, secondary, tertiary amines) and metal oxides may be used. In addition, as described above, an ultraviolet curable coating material is used to cure through an ultraviolet curing chamber or a chamber capable of electron beam irradiation.

As described above, according to the high-strength, high-gloss printing paper and the fiber manufacturing method through curing by ultraviolet or electron beam according to the present invention, the rapid workability at room temperature and atmospheric pressure through ultraviolet curing, the printing paper by lamination with the protective film And the hardened surface of the fiber has the effect of showing a high strength, high gloss.
