Description
Technical Field
The invention relates to a production process of a color coated plate, in particular to a production process of a TDX10 color coated plate.
Background
At present, the domestic times of surplus color coating productivity and high profit of color coated plates are declared to be over, the competition is more and more intense, and the color coated plates can gain the market competitiveness only by improving the product quality, expanding the market share of the products and adopting market segmentation and differentiated operation strategies. The technological development of color coated sheets has mainly surrounded the variation of the combination of coatings and coatings to meet different market demands.
The invention discloses a color-coated sheet and a preparation method thereof in the patent of CN201210092782.7, and provides the color-coated sheet and the preparation method thereof, the color-coated sheet comprises a substrate, the substrate is a steel plate with stamping deformation performance, the surface layer of the substrate is provided with a primer coating and a finish coating in sequence, a chemical conversion layer is arranged between the primer coating and the substrate, and the preparation method of the color-coated sheet comprises the following steps: 1) when the color-coated plate is prepared, firstly, the surface of a substrate is passivated to form a chemical conversion layer; 2) forming a primer coating on the surface of the chemical conversion layer by using coil coating; 3) and respectively forming a front coating and a back coating on two sides of the substrate with the primer coating by using coil coating. The color-coated sheet and the preparation method thereof enable the color-coated sheet to have good stamping performance in the color-coated production line, and can solve the problem that the coating is easy to crack or the substrate is easy to crack when the color-coated sheet is stamped.
The CN201510086879.0 patent is a production method of a color coated sheet with ultrahigh film thickness, and the method comprises the steps of degreasing by pretreatment, surface conditioning and hot water rinsing; the weight of the passive film is controlled to be 30-40 mg/m 2; the designed film thickness of the primer is 15 +/-5 mu m, and upper limit control is adopted; the designed film thickness of the finish paint is 25 +/-3 mu m, and lower limit control is adopted; the stirring speed and time of the premixing room are controlled, the set values of the wind speed and the temperature of the first section and the second section of the curing process are reduced by 20-30% compared with those of a common color-coated plate, the cooling water adopts desalted water, the conductivity is 70 mu m/s, and the cooling treatment time is 12-15 s; the thickness of the plate is less than or equal to 0.6mm, the initial weight of the coiling machine is 1900-2100 kg, the final weight is 2900-3200 kg, and the step tension is 140%; the thickness was > 0.6mm and the step tension ratio of the coiler was set to 40000/base tension. The invention can stably produce the color coated sheet with the ultra-high film thickness of 40 mu m and excellent corrosion resistance, wear resistance and better cost performance in a large scale, the yield reaches more than 95 percent, and the invention is a color coated sheet production process with high added value.
The coating weight of the color-coated substrate is mainly selected according to factors such as application, environmental corrosivity, service life and durability. The corrosion resistance is one of the main functions of the color-coated plate, and the coating weight is a main factor influencing the corrosion resistance of the color-coated plate. Since the color-coated sheet for construction is usually exposed to the atmospheric environment, a substrate such as a hot-dip galvanized sheet or a hot-dip aluminum-zinc sheet having high corrosion resistance and a thick coating layer is usually selected. The corrosion resistance is generally improved along with the increase of the coating weight, and the corrosion resistance of various coated steel plates is basically in direct proportion to the coating thickness, so the corrosion resistance of the color coated plate can be improved by increasing the coating weight. For example, in severe industrial pollution and coastal humid areas, 75/75-140/140 g/m2 hot-galvanized plates are generally used, and 30/30-50/50 g/m2 hot-galvanized plates or hot-dip aluminum-zinc plates are generally used as color-coated substrates required for corrosion prevention. The coating of the color coated steel plate generally has a thickness of about 20 to 25 μm on the upper surface, and the corrosion resistance is generally improved with the increase of the coating weight, and the coating film has protection effects such as scrub resistance, solvent resistance, pollution resistance, sunlight resistance, corrosion resistance and the like, so the color coated steel plate is widely used. The functions of the coatings are from the coating material itself and the good color coating production process. The properties of the coating are an important part of the impact on the coating performance. The paint is composed of four raw materials of resin, pigment, additive and solvent. The resin is the most important part of the coating, and forms a smooth and uniform film on the surface of a coated object. The excellent resin must have the following properties, can form a thin film and has good binding force to a substrate; has good dispersibility on the pigment and uniform color. The appearance is transparent and the chroma is low; resistance to the environment such as sunlight, air and moisture, acid rain, grease and smoke; has the performances of scrubbing resistance, abrasion resistance, collision resistance and the like.
The development of the color-coated sheet suitable for local climate characteristics is a development direction by combining the current demand situation of the local market in Xinjiang; the method is characterized in that the method is carried out on the vernix in Xinjiang, is far away from the sea, is dried all the year round in climate and has low requirement on corrosion resistance of the color-coated sheet, but the color-coated sheet on the market at present generally has thicker coating (about 20-25 microns) and thicker plating (30/30-50/50 g/m 2), and has resource waste when being used in Xinjiang, so that the method is urgently needed to develop a production process of an ultrathin plating thin-coating color coated sheet, and produce an economical color coated sheet suitable for the Xinjiang climate to improve the existing production technology.
