技术领域technical field
本发明涉及门业、家装、家电领域用钢带制造工艺，具体涉及一种仿木纹印花彩色涂层钢带的制造方法。The invention relates to a manufacturing process of a steel strip used in the fields of door industry, home decoration and household appliances, in particular to a manufacturing method of a color-coated steel strip imitating wood grain printing.
背景技术Background technique
随着人们对家居美化、装饰品味的不断提高，各种花纹钢板在家装(如门及门套、窗)、内外墙装饰、家电等领域的应用不断扩大，而仿木纹图案由于其柔和的色彩与丰富自然的木纹纹理广受追捧。为满足用户对此类产品花色品种的多样性、个性化需求，目前行业内都是采用钢板喷涂油漆，然后进行印花纸热转印方式实现，即：冷轧钢板表面经过清洗、磷化、粉末喷涂(或清漆)层、再通过热转印工艺，将热转印纸(印花纸)上的图案附着于钢板表面；或者在处理过的钢板表面黏贴PVC膜完成。这两种工艺存在的问题有：1)工艺繁琐，生产效率低下，钢板单张喷涂、热转印、覆膜，效率低；2)环境污染严重；3)产品质量批次之间重复性差，花纹立体效果不明显，极易褪色，耐老化性能不能满足高端市场的需求。With the continuous improvement of people's home beautification and decoration taste, the application of various pattern steel plates in home decoration (such as doors and door covers, windows), interior and exterior wall decoration, home appliances and other fields continues to expand. Colors and rich, natural wood grains are sought after. In order to meet users' diverse and personalized needs for such products, the industry is currently using steel plates to spray paint, and then heat transfer printing on printed paper, that is, the surface of cold-rolled steel plates is cleaned, phosphated, and powdered. Spray (or varnish) layer, and then through heat transfer process, attach the pattern on the heat transfer paper (printing paper) to the surface of the steel plate; or stick PVC film on the surface of the treated steel plate to complete. The problems existing in these two processes are as follows: 1) The process is cumbersome, the production efficiency is low, and the steel sheet is sprayed, thermally transferred, and coated, and the efficiency is low; 2) The environmental pollution is serious; 3) The repeatability between batches of product quality is poor, The three-dimensional effect of the pattern is not obvious, it is easy to fade, and the aging resistance cannot meet the needs of the high-end market.
基于环保、产能及产品质量的多种因素制约，现有热转印及覆膜工艺以及满足不了日益增长的仿木纹钢板的市场需求。Due to various factors such as environmental protection, production capacity and product quality, the existing thermal transfer printing and film coating processes cannot meet the growing market demand for imitation wood grain steel plates.

On the steel strip after cleaning and passivation, the base color (coating primer and back paint) and curing are initially applied; Print the wood grain pattern with quick-drying ink before the topcoat (coating varnish) process, and then apply the varnish and cure it in the finish coating section to obtain a color-coated steel plate with a clear wood grain pattern on the surface; improve production efficiency and improve product quality. Quality (pattern effect, durability, etc.), reduce environmental pollution.
基板为镀锌板或冷轧板。The substrate is galvanized sheet or cold rolled sheet.
镀锌板清洗工序为一次脱脂—二次脱脂—一次漂洗—二次漂洗—三次漂洗；一次脱脂及二次脱脂采用的碱液浓度为0.5-1.5％，槽液温度为50-65℃；一次漂洗和二次漂洗槽液温度为50-65℃，三次漂洗槽液温度为40-55℃。The galvanized sheet cleaning process is primary degreasing-secondary degreasing-first rinsing-secondary rinsing-three rinsing; the concentration of lye used for the first degreasing and the second degreasing is 0.5-1.5%, and the bath temperature is 50-65°C; The temperature of the rinsing and secondary rinsing baths is 50-65°C, and the temperature of the third rinsing baths is 40-55°C.
镀锌板清洗工序具体工艺参数见下表：The specific process parameters of the galvanized sheet cleaning process are shown in the table below:

图案印刷工序中，采用表面刻有木纹图案的印花辊，在印花辊表面涂覆快干油墨，实现图案印刷。印花辊为印花钢辊，模仿自然木材纹理(如：紫檀、红柳、橡木等等)设计图案，图案用激光雕刻在印花钢辊上，印花辊的径向周长为一个花纹周期。这样印花辊转动一圈即在钢带上留下一个完整的图案，使钢带上木纹图案均匀。In the pattern printing process, a printing roller with a wood grain pattern engraved on the surface is used, and quick-drying ink is coated on the surface of the printing roller to realize pattern printing. The printing roller is a printing steel roller, which imitates the natural wood texture (such as: red sandalwood, red willow, oak, etc.) to design the pattern. The pattern is engraved on the printing steel roller with a laser. The radial circumference of the printing roller is a pattern cycle. In this way, the printing roller rotates a circle to leave a complete pattern on the steel belt, so that the wood grain pattern on the steel belt is even.
如图1所示，印花辊底部设有盛放快干油墨的油墨槽，印花辊一侧设有刮刀，印花辊的另一侧依次为精涂用涂覆辊及支撑辊；印花辊转动过程中沾取油墨槽内油墨，实现钢带表面图案印刷；钢带从印花辊上穿出后穿入涂覆辊和支撑辊之间实现精涂。As shown in Figure 1, the bottom of the embossing roller is provided with an ink tank containing quick-drying ink, one side of the embossing roller is provided with a scraper, and the other side of the embossing roller is a coating roller and a support roller for fine coating in turn; the rotation process of the embossing roller The ink in the ink tank is dipped in the middle to realize the pattern printing on the surface of the steel strip; the steel strip passes through the embossing roller and then passes between the coating roller and the support roller to realize the fine coating.
涂层厚度及固化工艺参数如下表：Coating thickness and curing process parameters are as follows:
由上表可知，涂层钢带的正面底漆厚度为8-10μm，油墨厚度为1-2μm，正面罩光清漆厚度为7-10μm；背面漆厚度为5-8μm。It can be seen from the above table that the thickness of the front primer of the coated steel strip is 8-10 μm, the thickness of the ink is 1-2 μm, the thickness of the front varnish is 7-10 μm; the thickness of the back paint is 5-8 μm.
涂底漆和背面漆后固化温度(PMT)为224-232℃。The post-primer and backcoat cure temperature (PMT) is 224-232°C.
