Description

家电用拉丝类印刷彩钢板Brushed printed color steel plate for household appliances

技术领域 technical field

本实用新型属于家用电器外壳、建筑内外装饰等用的金属板领域,具体地说,涉及一种家电用拉丝类印刷彩钢板。 The utility model belongs to the field of metal plates used for housings of household appliances, interior and exterior decoration of buildings, etc., in particular to a drawing-type printed color steel plate for household appliances.

背景技术 Background technique

现有表面拉丝类彩钢板制作工艺,目前一般都是运用在包装以及建筑等非精细化领域,该类彩钢板是将铝箔类彩膜、PET+PVC覆合彩膜或PET彩膜贴覆在经高温烘烤后基板上(基板表面涂覆胶水)覆合而成,上述三类彩板具体如下: The existing surface drawing color steel plate production process is generally used in non-refined fields such as packaging and construction. This type of color steel plate is made by pasting aluminum foil color film, PET+PVC laminated color film or PET color film on After being baked at high temperature, it is laminated on the substrate (coated with glue on the surface of the substrate). The details of the above three types of color plates are as follows:

1)铝箔类拉丝效果彩板的彩膜结构:优先在铝箔膜表面进行勾丝,上面依次是颜色层、胶黏剂层、PET层、花纹图案层,即在铝箔类彩膜表面上压有拉丝类花纹图案,但目前使用铝箔类彩膜主要为进口,采购成本较高。 1) The color film structure of the aluminum foil type drawing effect color plate: the surface of the aluminum foil film is first hooked, and the top is followed by a color layer, an adhesive layer, a PET layer, and a pattern layer, that is, pressed on the surface of the aluminum foil type color film. Brushed patterns, but the current use of aluminum foil color films is mainly imported, and the purchase cost is relatively high.

2)PET+PVC覆合类拉丝类效果彩板的彩膜结构:PET膜上面压有花纹图案层,下面为依次为颜色层/蒸镀层、胶黏剂层、PVC。PET+PVC覆合彩膜层间附着力存在风险且含PVC材料,产品不环保。 2) The color film structure of the PET+PVC laminated wire drawing effect color plate: the PET film is pressed with a pattern layer, and the bottom layer is the color layer/evaporation layer, adhesive layer, and PVC. The adhesion between PET+PVC laminated color film layers is risky and contains PVC materials, so the product is not environmentally friendly.

3)PET拉丝类彩板的彩膜结构:PET膜下面为颜色层,上面压有花纹图案层。拉丝类PET彩膜由于PET原材料局限存在性能不合格。 3) The color film structure of the PET wire drawing color plate: the color layer is under the PET film, and the pattern layer is pressed on the top. Due to the limitations of PET raw materials, the performance of the brushed PET color film is not up to standard.

因此,上述三种彩膜结构的印刷彩钢板均不适合用于家用电器外壳领域。 Therefore, the printed color steel plates with the above three color film structures are not suitable for use in the field of housings of household appliances.

实用新型内容 Utility model content

本实用新型的目的在于提供一种家电用拉丝类印刷彩钢板,该拉丝类彩钢板用于家用电器外壳领域,降低了成本,产品附着力以及表面性能得到提升,而且更加环保。 The purpose of the utility model is to provide a drawing-type printed color steel plate for household appliances. The drawing-type color steel plate is used in the field of household appliance shells, which reduces the cost, improves product adhesion and surface performance, and is more environmentally friendly.

为解决上述技术问题,本实用新型采用以下技术方案予以实现: In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions to achieve:

一种家电用拉丝类印刷彩钢板,该彩钢板包括基板,在基板上面由下至上依次是化学处理层、底漆层、中涂层、拉丝印刷层、罩光层、保护膜层,基板下面由上至下依次是化学处理层、背漆层。 A wire-drawn printed color steel plate for household appliances, the color steel plate includes a substrate, on the substrate from bottom to top are a chemical treatment layer, a primer layer, a middle coat layer, a wire-drawing printing layer, a finish layer, a protective film layer, and the bottom of the substrate From top to bottom are the chemical treatment layer and the back paint layer.

其中,所述底漆层、中涂层以及罩光层采用涂料涂覆。所述涂料的主树脂采用线形树脂,该线形树脂的分子量范围:10000-25000。采用线形树脂,延伸性能好。而建材上用的涂料主树脂为网状结构,呈铰链形,延伸性能差。 Wherein, the primer layer, middle coat layer and finish layer are coated with paint. The main resin of the paint is a linear resin, and the molecular weight range of the linear resin is 10000-25000. Using linear resin, good elongation performance. However, the main resin of the paint used in building materials is a network structure, which is hinge-shaped and has poor elongation.

其中,所述拉丝印刷层采用油墨涂覆印刷。所述油墨的主树脂采用线形树脂,该线形树脂的分子量范围:10000-25000。而建材上用的油墨的主树脂分子量一般低于10000,通常在5000-10000之间。 Wherein, the brushed printing layer is coated and printed with ink. The main resin of the ink is linear resin, and the molecular weight range of the linear resin is 10000-25000. The molecular weight of the main resin used in building materials is generally lower than 10,000, usually between 5,000 and 10,000.

所述保护膜层采用PE保护膜。 The protective film layer adopts PE protective film.

本实用新型的拉丝类印刷彩钢板,由环保涂料以及油墨替代目前的铝箔类彩膜、PET+PVC覆合彩膜以及PET膜,涂覆于基板制成彩板,基板采用不锈钢板、电镀锌板、热镀锌板、镀铝锌板或镀锡板。由于目前涂料以及油墨都是符合国际ROHS检测标准,并且涂料的性能(耐污染、耐划伤、耐盐雾、耐酸碱)都明显高于彩膜的性能,因此本实用新型很好的解决了原材料不环保以及彩涂钢板性能局限的缺点。 The brushed printed color steel plate of the utility model replaces the current aluminum foil color film, PET+PVC laminated color film and PET film with environmentally friendly paint and ink, and is coated on the substrate to make a color plate. The substrate is made of stainless steel plate, electrogalvanized sheet, hot-dip galvanized sheet, galvalume sheet or tin-plated sheet. Since the current coatings and inks are in compliance with the international ROHS testing standards, and the performance of the coating (pollution resistance, scratch resistance, salt spray resistance, acid and alkali resistance) is obviously higher than that of the color film, so the utility model is a good solution It eliminates the shortcomings of raw materials that are not environmentally friendly and the performance of color-coated steel sheets is limited.

相比较传统的铝箔类拉丝彩钢板、PET+PVC覆合彩膜拉丝彩钢板或PET覆膜拉丝彩钢板,本实用新型的印刷类拉丝彩钢板具有以下优势: Compared with the traditional aluminum foil brushed color steel plate, PET+PVC laminated color film brushed color steel plate or PET film coated brushed color steel plate, the printing brushed color steel plate of the utility model has the following advantages:

成本降低:较铝箔类彩膜或PET+PVC覆合彩膜彩钢板,成本降低约30%; Cost reduction: Compared with aluminum foil color film or PET+PVC laminated color film color steel plate, the cost is reduced by about 30%;

性能优化:较PET覆膜拉丝彩板,性能更加优化,提高层间附着力; Performance optimization: Compared with PET coated wire drawing color board, the performance is more optimized and the adhesion between layers is improved;

环保:较PET+PVC彩膜覆合彩钢板,无PVC层,产品更加环保。 Environmental protection: Compared with PET+PVC color film and color steel plate, there is no PVC layer, and the product is more environmentally friendly.
