術についての提案である。Detailed Description of the Invention (Industrial Application Field) The present invention relates to a method for manufacturing a fluororesin film laminate plate, and particularly when bonding a thermoplastic fluororesin film having a melting point lower than the bonding temperature to the surface of a metal strip. The present invention proposes an advantageous technique in which the film can be bonded by the heat contained in the metal strip (hereinafter, the "copper strip" will be specifically referred to) without melting, breaking, stretching, wrinkling, etc.

ものが使用されてきたに過ぎない。(Conventional technology) Laminated steel sheets can be used in a wide range of applications depending on their characteristics depending on the type of resin they are coated with, so they are used in fields such as buildings, home appliances, vehicles, steel furniture, and objects. . However, in the field of long-term durability such as weather resistance, although there has been a market demand for it, there are few products that can meet it (,
For example, only polyvinyl chloride, polymethyl methacrylate, or a composite of these with polyvinyl chloride has been used.
この点に関し、本発明者らはポリぶつ化ビニリデンフィ

ミネート鋼板を製造することが困難であった。In this regard, the present inventors have focused on the excellent durability of polyvinylidene buttride film and have been conducting research on a film-laminated steel plate in which this film is adhered to a steel plate. However, most of the resin films that have been used under this technology have a melting temperature close to or higher than the bonding temperature, or have a film thickness of 80 μm or more, and are polyvinylidene butt films. There is no such film with a low melting point and a thin film, and the lamination process of such a film usually causes the film to melt and break, elongate, wrinkle, etc., and it is difficult to produce a normal laminated steel sheet. It was difficult.
またラミネートの分野で接着剤としては長期耐久性を有

採用して接着が行っているのが実情である。Furthermore, in the field of lamination, it is difficult to use thermosetting adhesives with long-term durability as adhesives, so it is difficult to lower the temperature, and there are no practical adhesives yet. The reason for this is that in the case of thermosetting adhesives, activation is imparted during thermal bonding, and sufficient activation cannot be imparted at low temperatures. Therefore, the current situation is that bonding is performed at a temperature of around 200°C.

There remained a problem to be solved in that it was not possible to properly laminate a thin thermoplastic fluororesin film with a melting point lower than the bonding temperature without causing melt rupture, elongation, wrinkles, etc.

、その解決手段として採用する。(Means for solving the problem) When manufacturing laminated steel sheets using a fluororesin film with a melting point lower than the bonding temperature, we have solved the problems faced by conventional technology, such as melt fracture, elongation, wrinkles, etc. The invention provides a method for thermally bonding a thermoplastic fluororesin film having a melting point lower than the bonding temperature to a metal strip whose bonding surface is coated with a thermosetting adhesive via a pair of upper and lower heated laminating rolls. A method for producing a fluororesin film laminate board, which is characterized by controlling the temperature of a heated laminating roll in consideration of the adhesive melting temperature and the film softening temperature, is adopted as a means for solving this problem.
そして、上記ラミネートロールの上ロール表面温度とし
ては、３０〜８０℃に保持する一方、同下ロール表面温
度としては８０〜１２０℃を好適温度範囲として採用す
る。The surface temperature of the upper roll of the laminating roll is maintained at 30 to 80°C, while the surface temperature of the lower roll is preferably set to 80 to 120°C.
（作 用） 以下にこの発明を想到した経緯について説明する。(for production) The background of how this invention was conceived will be explained below.
フィルム接着の基本要件は、第１にフィルム、接着剤双
方が充分に多くの接着活性点を有するようにすること、
第２にフィルム、接着剤の双方を可能な限り近づけるこ
とである２第１は、接着の主反応が水素結合であること
から、それが容易となるように双方を選択することで対
処している。The basic requirements for film adhesion are, first, that both the film and the adhesive have a sufficiently large number of adhesive active points;
The second is to bring both the film and the adhesive as close as possible.The first is that the main reaction of adhesion is hydrogen bonding, so it is necessary to select both in a way that facilitates this reaction. There is.
第２はフィルムが固相だから液状の接着剤を用いること
で対処している。ところが、接着後に長期にわたり安定
な接着力を与える接着剤としては熱硬化型のものの方が
液状のものより優れている。The second problem is that the film is in a solid phase, so a liquid adhesive is used. However, thermosetting adhesives are superior to liquid adhesives in providing stable adhesive strength over a long period of time after bonding.
このため熱硬化型の接着剤を用いる場合には、接着時に
フィルムの接着面を軟化ないしは溶融しており、いわゆ
る熱可塑性フィルムが用いられるのはこのためである。For this reason, when a thermosetting adhesive is used, the adhesive surface of the film is softened or melted during adhesion, and this is why a so-called thermoplastic film is used.
さて、ふっ素樹脂フィルムラミネート鋼板の場合、使用
するふっ素樹脂フィルムによっては、フィルム溶融温度
が接着温度より２０〜３０℃低く、そのため接着時に調
帯からの電熱により接着面から軟化、溶融が始まる。そ
の結果、特にフィルムが薄い場合には、フィルム張力、
接着速度、接着ロール加圧力によってフィルムの溶融破
断、伸び、しわが不可避に発生する。Now, in the case of a fluororesin film-laminated steel plate, depending on the fluororesin film used, the film melting temperature is 20 to 30° C. lower than the bonding temperature, and therefore, during bonding, the bonding surface begins to soften and melt due to the electric heat from the belt. As a result, film tension, especially when the film is thin,
Depending on the adhesion speed and pressure applied by the adhesive roll, melting, breakage, elongation, and wrinkles inevitably occur in the film.
そこで容易に接着可能ならしめるべく、種々の実験を重
ねた結果以下の事実を見出した。すなわち、
（１） フィルムの一方からフィルムの溶融に充分な
熱を供給する一方逆の方向から冷却すると、フィルムの
伸びや、溶融を招くことなくして接着ができる。そうし
た冷却方法は、フィルムに接触するラミネートロールの
上ロールの表面温度を制御することで可能となる。Therefore, as a result of repeated various experiments in order to make it possible to bond easily, the following facts were discovered. That is, (1) By supplying sufficient heat to melt the film from one side of the film and cooling from the opposite direction, adhesion can be achieved without stretching or melting the film. Such a cooling method is made possible by controlling the surface temperature of the upper roll of the laminating roll that comes into contact with the film.
（２） ラミネートローマの上ロールに接触して供給
されるフィルムは、薄膜のためしわが発生し易いが、ロ
ールの表面温度により加熱収縮が起り、接着点に達する
までにしわが消失する。(2) The film that is supplied in contact with the upper roll of the laminating roll is a thin film and is therefore prone to wrinkles, but heat shrinkage occurs due to the surface temperature of the roll, and the wrinkles disappear by the time the film reaches the bonding point.
（３） ラミネートロールの下ロール表面温度は、接
着時の銅帯の温度を安定化させるために重要である。(3) The surface temperature of the lower roll of the laminate roll is important for stabilizing the temperature of the copper strip during bonding.

１からの熱に耐えるため耐熱ゴムロールが用いられる。Therefore, based on such knowledge, we came up with a means to solve the above problem. That is, in the method of the present invention, first, the steel strip 1 is subjected to a chemical conversion treatment such as phosphate treatment or chromate treatment,
Thereafter, a thermosetting adhesive is applied using a roll coater 2 or other method, and then baked and cured using a heating furnace 3. After leaving the heating furnace 3, the steel strip 1 is immediately heated up and down 2 while retaining its heat.
The book is passed through a laminating roll 4. As the upper roll 4a of the laminating roll, a heat-resistant rubber roll is used to absorb minute irregularities of the steel strip 1, to prevent air from being drawn in during film adhesion, and to withstand heat from the high-temperature steel strip 1.
下ロール４ｂは、鉄ロールが用いられる。An iron roll is used as the lower roll 4b.

のため、相溶性の良い他の樹脂を加えるで接着性を改良
しているが、これによりフィルム５の溶融点が低下して
くる。このため機械的な方法でしわをなくすことはむす
かいしい。The film 5 is fed from an unloader under constant tension through several deflector rolls and expander rolls, along the upper roll 4a, and is thermally bonded to the steel strip between 1.2 and 2. At this time, the tension of the film 5 is selected to be such that the film does not wrinkle or stretch, but if the film 5 is thin and a soft film with a low melting point, wrinkles are likely to occur. In particular, in the case of a fluororesin film, when the amount of fluorine substituted in the fluororesin increases, the adhesiveness decreases because the film has a surface tension greater than that of the adhesive. For this reason, adhesion is improved by adding another resin with good compatibility, but this lowers the melting point of the film 5. For this reason, it is difficult to eliminate wrinkles using mechanical methods.
ところで、かかるフィルム５は、その製造上のフィルム

昇温を防ぐには充分でない。このため上ロール４ａの表
面温度を上記範囲にするためには、外部冷却の併用が好
ましい。Incidentally, the film 5 has a property that stress remains during film stretching during production and shrinks when heated. Therefore, when the wrinkled film 5 is brought into contact with the thermal laminator roll 4, the contact portion undergoes thermal contraction and the wrinkled portion is stretched. Table 1 shows the relationship between roll temperature, film tension, elongation, and wrinkle formation. As can be seen from the results shown in Table 1, the surface temperature of the upper roll 48 is 30°C to 80°C.
It can be seen that C1 is desirably within the range of 40°C to 60'C. However, in the case of continuous production, the conveyed steel strip serves as a heat supply source and raises the temperature of the laminating roll 4. Normally, the upper roll 4a is hollow and lined with rubber, and is cooled by internal water flow, but this is not sufficient to prevent heating from the surface. Therefore, in order to keep the surface temperature of the upper roll 4a within the above range, external cooling is preferably used in combination.
一方、下ロール４ｂも同様に鋼帯１から給熱昇温される
。下ロール４ｂは中空鉄ロールであり、昇温による歪み
を防ぐため通水冷却を行っているが、ロール表面温度が
下がり過ぎると、銅帯の温度を低下させ、接着不良を起
す。特に鋼帯の巾方向両端部の温度が下がり易（、端部
剥れを起し易い。On the other hand, the lower roll 4b is also heated by heat supplied from the steel strip 1. The lower roll 4b is a hollow iron roll, and is cooled by passing water to prevent distortion due to temperature rise, but if the roll surface temperature drops too much, the temperature of the copper strip will drop, causing poor adhesion. In particular, the temperature at both ends in the width direction of the steel strip tends to drop (and the ends tend to peel).
このため、ロールの保守と安定した接着を保持するため
の下ロール温度は、８０℃〜１２０℃、望ましくは９０
℃〜１１０℃の範囲が良い。Therefore, the lower roll temperature for maintaining the roll and maintaining stable adhesion is 80°C to 120°C, preferably 90°C.
A range of 110°C to 110°C is preferable.
