The dead long paper 200 is attached to the rear surface 150 of the acrylic plate 110 to give a mirror effect. Deadlon paper 200 is a condensation polymerization of terephthalic acid (terephthalic acid), dihydric alcohol and dihydric carboxylic acid (Carboxylic Acid) produced by oxidizing xylene (Xylene) in the air with a heavy metal such as cobalt or manganese catalyst Made of polyester, it is a material that is very thin, has a metallic feel, has excellent surface gloss, and has high resistance to water and moisture. The dead paper 220 is generally used for labeling electronics or home appliances. Since it is mainly used as a sticker or the like, detailed description thereof will be omitted.

The adhesive 210 used when attaching the dead long paper 200 to the back surface 150 of the acrylic plate 110 may include VMCH (manufactured by DOW, USA), toluene and methyl ethyl ketone (MEK). ) Is used in combination at a constant ratio.

VMCH is a kind of vinyl resin, a carboxyl-modified compound composed of 86% vinyl chloride, 13% vinyl acetate, and 1% maleic acid. Copolymer) and is provided in powder form.

In addition, VMCH is a product of Dow (DOW) of the United States and has excellent adhesion to metal materials and acrylic materials, and is widely used in fields such as aluminum foil, can coating, and cell phone coating using various metallic pastes.

When the VMCH is mixed with toluene in a one-to-one ratio, the powdered VMCH solidifies into a small grain form. After reacting for about 20 to 40 minutes (preferably about 30 minutes), mix the solidified pellets and MEK at a ratio of 3 to 2, and mix well for 20 to 40 minutes (preferably about 30 minutes). To be done. Since the mixed adhesive 210 is very toxic by the toluene component, it is necessary to remove the toxicity. Toluene toxicity occurs when toluene is volatilized, and the half-life of toluene itself is very short. Therefore, the toluene toxicity naturally disappears when it is sealed and aged for 2 to 3 days.

Therefore, the mixing ratio of VMCH, toluene, and MEK becomes 3: 3: 4 by weight ratio, and the method of attaching the dead paper 200 to the back surface 150 of the acrylic plate 110 is as follows.
