C Introduction三、导言



Many different types of finishes may be applied to metal surfaces by coil coating. These finishes include paints, whose properties are strongly influenced by the resins used in the formulation, and plastic films that may be laminated to the metal strip.






Alkyds are the condensation product of polybasic acids and polyhydric alcohols (polyls). Chemically, alkyds are polyesters, but alkyds are formulated with drying or non-drying oils while polyester are oil-free. Coatings based on alkyd resins tend to be relatively low cost but exhibit poor durability. Alkyd resins are often modified with other resins to obtain specific properties.

多元醇酸树脂由多元酸和多元羟基缩聚而成。用化学方法来表示，多元醇酸树脂称为聚酯。但是多元醇酸树脂由干油或非干油组成，聚酯树脂由无油的。在多元醇酸树脂为基础的涂料成本较低但耐久性不佳。多元醇酸树脂通常用其它树脂改性以获得特殊的特性。



Amine alkyd finishes are also referred to as alkyd/amino types. An amine or amino resin is the alkylated reaction product of urea or melamine and formaldehyde. The alkyd is cross-linked by the amino resin during baking.

氨基醇酸涂料—通常指氨基醇酸类型。含胺基或氨基树脂是尿素或三聚氰胺和甲醛 烷基化反应产品。这种醇酸是氨基树脂在烘烤时交联而成。

Silicone alkyd coating are based on either the reaction product of a silicone intermediate and an alkyd resin, or a cold blend of silicone resin and compatible alkyd resin. Silicone alkyds are generally cross-linked with amino resins. They have improved exterior durability.

硅多元醇酸树脂涂料在硅树脂和聚酯反应为基础的而得到的产品。或硅树脂和它相容性的多元醇酸树脂共混物。硅多元醇酸树脂通常用氨基树脂作为交联剂。它们已发展成为室外耐久性材料。

Acrylics are synthetic resins made from derivatives of acrylic acid. Thermoplastic acrylics (lacquers ), thermosetting acrylics, and acrylic latexes are available; the latter two are used in coil coating.

丙烯酸涂料是由丙烯酸衍生物经化学合成的树脂。热塑性丙烯酸和热固型丙烯酸(涂料)和丙烯乳液是可供应的，后两者可用于卷钢涂料中。

Thermoset acrylic coating are based on resins prepared from acrylic and methacrylic esters, acrylic and methacrylic acids, and /or styrene. They contain one or more functional group such as amide, hydroxy, or carboxy. They are cross-linked with themselves, amino, or epoxy resins. Acrylics may also be modified with other resins.

热固型丙烯酸涂料是由丙烯酸和甲乙基丙烯酸酯，丙烯酸和甲基丙烯酸，或苯乙烯反应而成。它们含有一个或多个功能团如：氨基、羟基、羧基。它们可以自交联，或和氨基、环氧树脂进行交联。丙烯酸也可以被其它树脂改性。

Silicone acrylic resins can be either the reaction product of a silicone intermediate with acrylic monomers, or a cold blend of silicone resin and acrylic polymers.

硅丙烯酸树脂是由硅树脂和丙烯酸单体反应而得到的产品，或是硅树脂和丙烯酸类聚合物的共混物。

Polyester resins are the condensation products of polybasic acids and polyols. Polyesters are sometimes refereed to as oil-free alkyds. They may be modified by the addition reaction of other monomers, such as styrene or acrylic esters. Polyester resins are generally cross-linked with amino resins during baking.

聚酯树脂是多元酸和多元羟基化合缩聚而成。通常情况下，聚酯也叫无油醇酸。它们可以被加以其它单体而改性，如苯乙烯、丙烯酸酯。在烘烤条件下，聚酯树脂通常用氨基树脂进行交联。

Silicone polyesters resins are the reaction product of organo-siloxane intermediates and a suitable polyester resin intermediate (typically characterized by the absence of drying oils ). These resins are generally cross-linked with amino resins. Coil coating made from silicone-modified polyester resins are often referred to as SMPs.

硅改性聚酯树脂是有机硅氧烷和相应的聚酯树脂中间产物反应而得到的产品。(典型的由无干油)，这种树脂通常用氨基树脂作为交联剂。卷材涂料所用的硅改性聚酯树脂经常称作SMP。

Vinyl resins are available to coil coaters in several forms.

乙烯基树脂用于卷材涂料有以下几种形式。

Solution vinyl coating are based on copolymers or terpolymers of vinyl chloride, vinyl acetate, and other monomers. Solution vinyl are thermoplastic, but some cross-linking may be accomplished when reactive groups are present.

、 可溶解乙烯基树脂是氯乙烯、醋酸乙烯和其它单体共聚物或三元共聚合物。可溶解乙烯基树脂是热塑性树脂，当有反应基团存在时，可发生交联反应。

Vinyl alkyd coatings are based on the blend of a copolymer ( or more commonly terpolymer ) of vinyl chloride, vinyl acetate, and vinyl alcohol with a compatible alkyd resin. These are thermoplastic coatings, but may approach the performance of thermosetting coatings by the incorporation of amino resins. The amino resin will cross-link not only the alkyd but the hydroxyl portion of the vinyl terpolymer.

乙烯基多元醇酸涂料是氯乙烯、醋酸乙烯和乙烯醇共聚物(或其它的三元共聚物)和相容的多元醇酸树脂的共混物。它们是热塑性涂料，当它和氨基树脂结合时，也可达到热固涂料的某些特性。氨基树脂不仅能和多元醇酸交联，而且和乙烯三元共聚物中的羟基部分反应。

Plastisol coatings are dispersions of finely divided higher molecular weight polyvinyl chloride resins in plasticizers. During the baking process the finely divided resin particles dissolve in the plasticizers. These particles fuse into a tough, flexible plastic film on cooling. Solvent can be added to plastisol coating to lower the viscosity, producing organosol coatings.

塑性溶胶涂料高分子量聚氯乙烯树脂非常精细地分散在增塑剂中而形成的涂料。在烘烤过程中，这些精细分布的树脂粒子溶解在增塑剂中。这些粒子在冷却过程中熔合成韧性、柔性塑料膜。可加入溶剂到塑性溶胶涂料中以降低它的粘度，形成有机溶胶涂料。

Epoxy are synthetic resins formed by reactions of compounds containing epoxy groups. The most common epoxies are those made from the reaction of bisphenol A with epichlorohyrin. These resins are typically cross-linked with amino or phenolic resins.

环氧树脂是化学合成的树脂，它由含环氧基的化合物反应而成。最平常的环氧由双酚A和环氧丙烷反应而成。这种树脂通常由氨基或酚醛树脂作交联剂反应而成。

Epoxy ester coatings are based on resins prepared by the esterfication of an epoxy resin with fatty acids. Because of their excellent adhesion to metals, epoxies are widely used as primers.

环氧酯涂料环氧树酯和脂肪酸酯化的基础上制作的树脂。因为它的对金属优异的附着力，环氧树脂被广泛应用于底漆。

Fluoropolymer-based coatings are usually based on a dispersion of finely-divided resin particles in dispersants and diluents.
