点があつた。 Conventionally, when bonding acrylic resin materials with a solvent, methylene dichloride and ethylene dichloride have been widely used. Furthermore, it is possible to use the same solvent as the acrylic resin material when bonding the polycarbonate resin material with a solvent. However, when methylene dichloride or ethylene dichloride is used to bond an acrylic resin material and a polycarbonate resin material with a solvent, the bonded area turns white, significantly impairing the appearance, and especially when a transparent material is used, the product cannot be used. It was hot.
本発明は、このような状況に鑑み、アクリル樹

これらを単独にあるいは併用して使用する。 Methylene dichloride or ethylene dichloride used in the present invention is generally used for solvent bonding.
These may be used alone or in combination.

防ぐことができる。 Methanol is added for the purpose of lowering the solubility of methylene dichloride and/or ethylene dichloride in acrylic resin materials and polycarbonate resin materials, but since adding a large amount will significantly reduce the adhesion speed, the It is necessary to adjust the mixing amount within the range of 150 parts by weight. Adding methanol in this way can prevent whitening of the bonded area.
さらに接着部分に発生する白化を防止し、同時

着剤組成物に必要に応じて、一般に用いられてい
る助剤や安定剤等を添加することができる。 Furthermore, in order to prevent whitening that occurs in the bonded area and at the same time to prevent bubbles that occur at this time, glacial acetic acid is added from 5 to 5.
Add 40 parts. If this amount exceeds 40 parts, whitening will appear again, which is not preferable. Additionally, commonly used auxiliaries, stabilizers, etc. can be added to the adhesive composition of the present invention, if necessary.
以下、具体的実施例について説明する。 Specific examples will be described below.

めて美麗であり、充分な接着強度も得られた。Example 1 A transparent acrylic resin plate with a thickness of 2 m/m (Acrylite L manufactured by Mitsubishi Rayon Co., Ltd.) and a transparent polycarbonate resin plate with the same thickness (Iupilon) were used.
(manufactured by Mitsubishi Gas Chemical Co., Ltd.) was cut into a size of 100 x 100 m/m, and a mixed composition of 100 parts of methylene dichloride, 100 parts of methanol, and 20 parts of glacial acetic acid was poured with a syringe between the stacked resin plates, and the load was applied. I applied it. After several minutes, the bonded area was observed and was found to be very beautiful with no whitening or bubbles, and sufficient adhesive strength was obtained.

It was cut into pieces and bonded together in the same manner as in Example 1 using a mixed composition of 100 parts of ethylene dichloride, 80 parts of methanol and 10 parts of glacial acetic acid. As in Example 1, the bonded portion had a beautiful appearance and excellent adhesive strength.
