Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a flame-retardant flocked decorative board for building materials, in which piles whose surfaces have been subjected to flame-retardant treatment are flocked to a plate-like substrate.

Traditionally, this type of decorative board is made by applying a desired base material to the surface of a substrate such as plywood or fiberboard, and then printing a pattern, or by printing a pattern on decorative paper, decorative cloth, synthetic resin sheet, etc. is attached.

By the way, such a conventional decorative board has a smooth surface, lacks a three-dimensional effect, and is poor in design. Furthermore, the substrate, surface decorative paper, decorative cloth, etc. are flammable, and have poor fire retardancy and flame retardant properties. Also, except when fiberboard is used as a substrate, sound absorption and heat retention are poor. Further, when the substrate is a fiberboard, although the fiberboard itself has sound absorbing properties, the surface is covered with a decorative surface, which ultimately reduces the sound absorbing effect.

Furthermore, in some cases, a large number of small holes are drilled into the decorative board in order to maintain its soundproofing effect, but drilling such a large number of small holes not only involves a complicated process, but also impairs the design. also decreases.

It is an object of the present invention to solve the problems of conventional decorative boards of this type.

In other words, if necessary, pattern printing, decorative paper, etc.
By electrostatically flocking long pile PL and short pile _P2 , which have been previously treated with flame retardant treatment C over the entire length, on the surface of a plate-like substrate coated with decorative cloth, etc., flame retardant properties, soundproof properties, and heat retention properties are achieved. The purpose is to provide a decorative board with a high degree of design.

Embodiments of the present invention illustrated in the drawings will be described below.

(Explanation of Examples) First, the manufacturing method of the decorative board of the present invention will be explained.

(1) First, the adhesive 2 is applied to the entire surface of a combustible plate-like substrate 1 such as plywood or fiberboard or partially in a pattern. Adhesives include epoxy, phenol, vinyl chloride, vinyl acetate, natural or synthetic rubber, polyurethane, solvent-based adhesives such as acrylic esters, emulsion-type organic adhesives such as vinyl acetate, acrylic esters, and synthetic rubber, or water glass. Inorganic adhesives and the like are used.

The adhesive 2 may be used depending on the type of decorative surface, such as one that becomes transparent after curing, one that is originally transparent, one that is translucent, or one that is originally colored and opaque.

The adhesive 2 is applied to the entire surface of the substrate 1 or partially in a pattern using a spreader, a roll coater, a gravure printer, a screen printer, or the like.

The plate-shaped substrate may be subjected to surface treatment such as sealing treatment, sealer treatment, sanding treatment, undercoating, intermediate coating, or pasting with paper or cloth, as required.

A decorative paper or cloth printed with a pattern or a pattern may be attached to the surface of a plate-like substrate that has been subjected to a base treatment.

(2) Next, the long pile p ₁ and the short pile p ₂ , in which the flameproofing treatment c has been applied to the front surface of the substrate 1 or the adhesive 2 partially applied to the entire circumference, are used in a normal electrostatic flocking device. The hair is transplanted using a method to form an uneven surface.

Flame-retardant long and short piles _p1 and _p2 include synthetic fiber piles such as human silk, suffu pile, nylon, vinyl, and corderan, short fibers such as wool pile, and long fibers containing phosphorus-containing organic substances, water-soluble amino, and plush. Those treated with flame retardants such as trinic acid and thiourea, or those treated with vinyl chloride are used.

Some flame retardants also have water repellent properties.

The piles p ₁ and p ₂ are selected depending on the desired surface design, such as transparent piles, opaque piles, or optionally colored piles.

(3) After the piles p ₁ and p ₂ are electrostatically flocked, they dry and harden.

(4) If necessary, a top coat may be applied to the entire surface without filling the piles p ₁ and p ₂ .

In this way, by combining the long and short piles p ₁ and p ₂ in a pattern, a decorative board having an uneven surface and fireproofing performance can be obtained. In addition, since the decorative board of the present invention imparts flame retardant properties to the entire surface of the decorative board, it is desirable that the piles p ₁ and p ₂ be planted over a fairly wide area even when the piles p 1 and p 2 are partially flocked. Furthermore, by applying flocking not only to the surface of the substrate 1 but also to the butt end surface, it is possible to prevent flames from penetrating through the joint joint.

(Effects of the present invention) (a) Since the piles p _{1 and} p ₂ are subjected to the flameproofing treatment c, the flameproof flocked layer 3 is formed on the surface of the substrate 1 by the piles p 1 and p ₂ . Therefore, when a fire occurs, it exhibits a flame-retardant effect and prevents spread of fire. However, in order to exhibit the flameproof effect at this time, it is desirable that the flameproof flocked layer be densely flocked over most of the surface area of the substrate 1. If the flocked area is too small or coarse, the flame retardant effect cannot be achieved.

(b) Since the long pile p ₁ and the short pile p ₂ are combined to partially and mechanically form an uneven surface, a sense of luxury is imparted to the design. In addition, long pile p ₁ and short pile p ₂ have been previously treated with flame retardant treatment e over their entire length, so long pile p ₁ and short pile p 2
The flame retardant layer is completely formed even in the space between p2 and _p2 . If flame retardant treatment is applied after flocking, the flame retardant will not penetrate well between long pile p ₁ and short pile p ₂ , unlike when flocking piles of the same length.

(c) A pattern such as pattern printing, decorative paper, decorative cloth, etc. is applied to the surface of the plate-shaped body in advance, and the pile p ₁ ,
By keeping p ₂ transparent, the piles p ₁ , p ₂
You can see the pattern on the board through it. The pattern seen through the transparent pile gives a mysterious feeling to the human eye, and can significantly enhance the design.
