The present invention relates to a method of bonding a plastic sheet to a steel material. Conventionally, plastic sheet steel sheets are produced by applying an adhesive onto the steel material, heating and drying it at a high temperature of 200°C to 280°C for a short time, and then immediately stacking the plastic sheets on top of each other and pressing them together by passing them between a pair of rubber-coated steel rolls. However, in this method,
Since the plastic sheet comes into contact with the high-temperature steel material, there are drawbacks such as the embossed pattern previously provided on the plastic sheet being destroyed, and the lamination of relatively thin plastic sheets being difficult. From the viewpoint of resolving these problems and saving resources and energy, there is a strong desire for an adhesive capable of low-temperature bonding. The present inventors previously proposed a method of using an electron beam as a low-temperature bonding method between a plastic sheet and a steel material. In other words, an electron beam curing adhesive is applied directly onto a surface-treated steel plate, the plastic sheet and the steel are then bonded together, and the adhesive is cured by irradiation with electron beams.This method provides excellent initial adhesive strength. However, when a boiling water test or a long-term moisture resistance test is conducted, there is a problem in that the adhesive strength significantly decreases. The inventors of the present invention have conducted intensive research to produce plastic sheet steel plates with good adhesion even after boiling water and moisture resistance tests, and have discovered that a method of forming a thermosetting coating on steel materials is highly effective. The invention has been completed. The present invention is a plastic film characterized in that a thermosetting paint is applied to a steel material, dried and hardened, and then an electron beam curing adhesive is applied and a plastic sheet is laminated, and the surface of the plastic sheet is irradiated with an electron beam. This is a method of bonding sheets and steel materials. Thermosetting paints used in carrying out the present invention include thermosetting acrylic paints, thermosetting epoxy paints, thermosetting urethane paints, etc.; Considering the environmental protection of the entire process of manufacturing plastic sheet steel sheets, it is especially preferable to use water-dilutable thermosetting acrylic paints. The coating amount of the paint is preferably in the range of 1 to 5μ,
Outside this range, the effects of the present invention will be reduced. As the electron beam curing adhesive used in the present invention, a resin mainly composed of a compound having 0.5 to 12 polymerizable unsaturated groups per 1000 units of molecular weight is preferably used, and pigments and dyes are blended as appropriate. However, if the number of unsaturated groups in the compound is less than this, the crosslinking curability of the compound will decrease, while if it is larger than this, the resulting cured product will become brittle, which is not preferred. Specific examples of these compounds include (1) α, maleic acid, fumaric acid, itaconic acid, etc.
Unsaturated polyester obtained from polycarboxylic acid containing β-unsaturated dicarboxylic acid and polyhydric alcohol, styrene, vinyltoluene, (meth)
Mixtures with acrylic esters (2) Epoxy polyacrylates obtained by modifying polyepoxy compounds with carboxyl group-containing vinyl monomers (3) Polyisocyanate compounds modified with hydroxyl group-containing vinyl monomers alone or in combination with polyol compounds Urethane polyacrylates (4) Polyester polyacrylates (5) Polyol polyacrylates and vinyl monomers such as polyethylene glycol di(meth)acrylate, 1,4 butanediol (meth)acrylate, trimethylolpropane tri( Examples include meth)acrylate, dipentaerythritol penta(meth)acrylate, (meth)acrylic acid esters, styrene, vinyltoluene, butoxymethylacrylamide, vinylpyrrolidone, dimethylacrylamide, and the like. In order to cure the adhesive by irradiating the adhesive with an electron beam, an electron beam with a dose rate of 0.1 to 100 Mrad/sec is taken out from an electron beam accelerator with an acceleration voltage of 0.1 to 20 Mev,
It is sufficient to irradiate at an absorbed dose of 0.5 to 20 Mrad. In the following examples, parts mean parts by weight. Example 1 An undercoat obtained by kneading 100 parts of water-dilutable thermosetting acrylic resin HW-135 (manufactured by Mitsubishi Rayon), 30 parts of titanium oxide, and 5 parts of strontium chromate was coated on a zinc phosphate-treated steel plate to a thickness of 3 μm. It was coated and cured by heating at 250°C for 70 seconds.
Next, urethane polyacrylate resin UK-
An adhesive consisting of 100 parts of 6039 (manufactured by Mitsubishi Rayon) and 40 parts of tetrahydrofurfuryl acrylate was applied to the base coat treated steel plate to a thickness of 5μ,
Soft vinyl chloride sheets (thickness 0.15 mm) were overlapped. After that, the acceleration voltage is 300Kev, the current strength is
The sheet surface was irradiated with an electron beam at 40 mA with an absorbed dose of 5 Mrad. A vinyl chloride sheet steel plate () obtained by this method, and a vinyl chloride sheet steel plate (2) produced in the same manner except that an electron beam curing adhesive was applied directly to the steel plate without applying an undercoat coating. Table 1 shows the adhesive strength. As is clear from the adhesive strength measurement results shown in Table 1, the vinyl chloride sheet steel plate produced by this method exhibits excellent adhesive strength not only in the initial adhesive strength but also after boiling water and water resistance tests.

After that, an acrylic film (manufactured by Mitsubishi Rayon, thickness 75μ) was placed on top of the film, and an electron beam was irradiated under the same conditions as in Example 1 to a thickness of 3 Mrad. The acrylic sheet steel plate obtained by this method showed excellent initial adhesive strength and passed the boiling water test and 200
No decrease in adhesive strength was observed even when a moisture resistance test was conducted over time.
