本発明は新規な鋼板用塗料組成物及び該塗料組成物を塗

プレコート鋼板が提案されても実用的に市販されること
は少ないのが実情である。After forming a coating film, the pre-painted steel sheet is cut and used for various purposes.So-called pre-painted steel sheets began to be used as building materials in the 1950s, and in recent years have been further expanded to include home appliances and other uses. It's coming. In addition to this situation, various improvements have been made to paint compositions and coating methods due to consumers' preference for luxury products and diversification of preferences.
board is proposed. However, pre-coated steel sheets are painted at high speeds, and in the market where they are actually used, painted sheets with different lofts (LoL) are used mixed (so-called bonding), so the color tone and appearance between the painted lofts are different. The reality is that even if new pre-coated steel sheets are proposed, they are rarely put on the market.
前期した消費者の高級化志向や嗜好を満足させるプレコ

６７号公報参照）。As a coating composition for pre-coated steel sheets that satisfies the consumer's desire for luxury and preferences, for example, it is possible to apply a high-molecular-weight, inert, non-elastic,
A compound containing organic fine particles with high abrasion resistance has been proposed, and it has been shown that this compound gives the paint an uneven appearance and improves hardness, abrasion resistance, etc.
(See Publication No. 67).
しかしながら、かかる塗料組成物を用いた場合には、近
年の消費者の嗜好であるつや消し状の落着いた重厚な光
沢外観が得られず、この塗料組成物に対して通常の手段
で光沢を低下せしめようとした場合、塗膜の耐久性を著
しく低下せしめる。However, when such a paint composition is used, it is not possible to obtain the matte, calm, and heavy gloss appearance that is desired by consumers in recent years. If you try to do so, the durability of the paint film will be significantly reduced.
さらにかかる塗料組成物を用いて通常のプレコート塗装
を実施した場合には、有機微粉体の塗膜中における分散
状態が、塗装速度、塗装膜厚等の微妙な条件差によって
著しく変わるのみならず、場合によっては偏在が発生し
、その結果塗膜の凹凸部の片寄りや、波の深さの不均一
が生じるため、プレコート鋼板としての商品価値が全く
ないものとなる。Furthermore, when ordinary pre-coating is carried out using such a coating composition, the dispersion state of the organic fine powder in the coating film not only changes significantly due to subtle differences in conditions such as coating speed and coating film thickness, but also In some cases, uneven distribution occurs, and as a result, unevenness of the uneven parts of the coating film and non-uniformity of the depth of the waves occur, so that the pre-coated steel sheet has no commercial value at all.
そこで、本発明者らは、かかる前記欠点を解消したプレ

It can be applied to anything, and the coating form may be a long coil or a short sheet-shaped cut plate as long as curtain coating or roll coating is possible. Furthermore, when painting, if the surface of the material to be painted is not contaminated with oil or other contaminants, it may be painted as is, but in order to improve the adhesion and corrosion resistance between the paint film and the paint film, metal surface treatment using known techniques can be applied. It is desirable to apply These known surface treatment methods include phosphate-based surface treatment, chromate-based surface treatment, and coating treatment with a chromic acid-based coating agent. In addition, when it is necessary to improve the quality of the coating film, it is preferable to apply the primer coating after the metal surface treatment and then apply the coating composition of the present invention. Applicable primers include the known primers currently used for colored steel plates, and are selected appropriately depending on the type of steel material to be painted and the type of metal surface treatment, but in particular, epoxy-based and/or polyester-based primers and their modified Primers are preferred, and if processability is particularly required, polyester primers are preferred.

In particular, in the case of a paint containing large organic fine particles, the curtain coating method is suitable. When applying a roll coating method, a top feed method using three rolls is recommended in order to achieve the best uniformity of the coated surface, but for practical purposes, a bottom feed method using ordinary two rolls may also be used.
