Description

TECHNICAL FIELD The present invention relates to an environmentally friendly flame retardant wallpaper, a method of manufacturing the same,

The present invention relates to eco-friendly flame retardant wallpaper of mineral material, and a manufacturing method and apparatus. More specifically, the base material, which is a base material of a wallpaper, is a flame retardant mineral and has a flame retardant effect. In addition, since a water-based printing composition and a foam composition are used, a flame retardant Wallpaper and a manufacturing method thereof.

In modern society, chemicals are useful in all industrial fields, but the effects of some harmful components on nature and human health are severe. So now the environmental problem is not a matter of one industry or one country, but a common problem of humanity.

In general, wallpaper is largely divided into base paper, paper wall paper, vinyl wallpaper, and fiber wallpaper according to the base material, that is, paper base paper made of paper as base paper. . In recent years, however, vinyl wallpapers are not only highly productive, but also capable of expressing a variety of colors and designs. They are highly resistant to pollution and moisture, and are widely used in public facilities such as hotels. It is gradually increasing. However, in the case of joint facilities, flame-retardant treatment or flame-retardant treatment is essential, and therefore, the cost of flame-retardant treatment is high.

Here is a brief overview of the manufacturing steps of PVC wallpaper (PVC) foamed wallpaper and double-layered paper laminated wallpaper.

◇ Hollywood vinyl (PVC) foam wallpaper

Application → Printing → Valfosol application (Plastisol) → Foaming (Thermal chamber) → Drying

◇ Two-ply paper lined foam wallpaper

Mainland → Printing → Insulation (not applied) → Embossing → Drying (Heat chamber)

1, a foamed resin composition is applied to a vinyl wallpaper paper by a known cotta method, passed through a thermal chamber at 100 to 150 캜 to be fixed, cooled, Roll on a roll to make the printing paper. It is again hooked to the unwinding machine 101, and the printing process, the foaming and the embossing process are finished in a serial process. Specifically, printing paper is made through a printing process 120 including a plurality of printers 102a to 102f, hot air is blown into a hot air chamber 104b from a heating chamber 103 at 140 to 180 deg. The layer is gelled and foamed. Then, the layer is heated to 200 to 230 DEG C in the auxiliary heater 104a, and then the embossing roller 105 is embossed with the engraved angles in a state in which the unfolded portion is formed. And cooled by the auxiliary cooling rollers 107 and 108, the embossed foam wall is completed while the yang angle is fixed, and is wound on the roll 109.

2, the foaming composition is applied (211), printed (212) and foamed (213) to the upper body (210), and the adhesive agent is applied The embossing roller 216 and the engraved roller 217 are embossed by laminating the two at the joint rollers 215a and 215b and moved to the heat chamber 218 to fix them. (219) is performed to produce a paper foamed foam wallpaper.

As a method for imparting flame retardancy or flame retardancy to a wallpaper, a flame retardant wallpaper using a flame retardant or a flame retardant can be cited as a conventional technique related to a flame retardant or flame retardant wallpaper. In the registration room No. 20-0219294, a flame retardant such as phosphoric ester Which has been impregnated with a flame-retarding agent, is adhered to a flame-retarding medium impregnated with a flame-retarding agent. However, the polyamide fiber of the flame retardant wallpaper is an expensive material as a synthetic paper (trade name " Nomex " manufactured by DuPont, USA) mixed with a mixture of aromatic amide polymer short fibers (registered trademark "Kevlar" . It is difficult to use it as a practical general-purpose wallpaper, and since the flame-retarded medium and the upper polyamide paper are adhered together and embossed together, it is difficult to produce a smooth surface of the medium, There arises a problem that the pattern is shifted in the printing process. In addition, Japanese Laid-Open Patent Application No. 10-2010-0001456 discloses a flame-resistant wallpaper composed of a base layer composed of synthetic fibers, natural fibers and a mixture thereof, a flame-retardant layer composed of phosphate, silicate, borate, phosphorus and organic flame retardant, . In addition, Japanese Laid-Open Patent Application No. 10-2009-0026000 discloses a flame-retarded wallpaper printed by a digital printing method by bonding flame-retarded raw paper and fibers made of a flame retardant composed of ammonium sulfamate and dicyandiamide. In addition, Patent Registration No. 10-0937092 discloses a wallpaper comprising a surface film layer made of a polyethylene film, a lower film layer and a master batch in place of PVC as wallpaper which can block the harmfulness of existing PVC wallpaper. However, the common point is that when all the raw paper used as the substrate is paper, synthetic resin or fiber, when paper is lighted, the paper serves as a flash bulb, and synthetic resin or fiber also generates fire or organic compounds to suffocate people. Therefore, in many of the prior arts, a suitable flame retardant is blended with a foaming composition or a printing composition to provide a flame retarded wallpaper. As can be seen from these prior arts, the problem of flame retardancy and flame retardancy is not a method other than flame retarding treatment or flame retardancy treatment. However, these techniques are not flame retarding treatment of substrates, but they are not only a temporary flame retarding effect but also a fundamental effect of flame retarding or flame retarding effect.

Practical registration No. 20-0219294 'Flame-retarded wallpaper' Open Patent No. 10-2010-0001456 'Flame-retardant wallpaper capable of inkjet printing' Patent Publication No. 10-2009-0026000 'Flame-retarded wallpaper of digital printing method using flame-retarded raw paper'

The inventors of the present invention have conducted extensive researches to solve the above problems, and have found that the use of mineral paper as a base material can fundamentally solve the problem of flame retardancy and flame retardancy, , And finally the invention was completed.
