Abstract
The invention relates to a production method of a suede color-coating steel plate, which comprises the following steps: (1) first cleaning the surface of the steel plate; (2) then using a pretreating agent to perform double-faced pretreating on a coating section, controlling temperature of the steel plate to be at 90 DEG C, and forming a pretreating coating after solidification; (3) perform primary coating to the steel plate, coating primer on two faces of the steel plate, controlling the temperature of the steel plate to be at 220-230 DEG C, forming a primer coating after solidification, and perform fast water cooling after the temperature of the steel plate reaches 225 DEG C; (4) finally performing fine coating treatment, coating suede coating on the front of strip steel, coating back paint on the back surface of the strip steel, controlling the temperature of the steel plate not to exceed 260 DEG C at maximum, and performing fast water cooling after a slow cooling process in a furnace is performed when the temperature of the steel plate reaches 260 DEG C; and (5) adopting a stretching straightener to stretch and straighten the steel plate, and using a stretching straightening roller to rub down a protrusion arranged on the surface of the steel plate. The production method of the suede color-coating steel plate solves the problem that a steel roll collapses easily in the suede color-coating steel plate.
Description
Technical field
The present invention relates to the production method of a kind of production method of steel plate, particularly a kind of suede color-coating steel plate.
Background technology
So-called " coating for woolen surface ", refers to people and in vision and sense of touch, it is filmed and experiences the sub dued lustre of textile-like, velour leather, soft, smooth feel etc. and have " the high-decoration coating of matte effect.Advanced, comfortableization, personalized and naturalized inevitable outcome are pursued in the appearance of this coating just consumer.The application of coating for woolen surface is increasingly extensive, except being applied to automobile and vehicle interior, decorate, household electrical appliance, office equipment, precision instrument and furniture, leather flies swiftly outside product,, with in interior decoration fields such as commercial building, hotel, hotel and families, is also the third generation building flawless finish coating of current international popular.
But along with the continuous increase of client to product purpose, the color coating product of the high added value that some are new develops thereupon, for example coating for woolen surface steel plate.But because this coating surface is more coarse, fineness is poor, and coating projection is more, lines is heavier, more similar to flannelette cloth cover, but want coarse many, and because coating surface projection is more, lines sense is stronger, with the contact between steel, being now projection and protruding contacting, is 50% left and right of other coating surface smooth product band steel Contact area at ordinary times, and contact friction force is less, curling tension force is less than the stress reverse with it, and volume collapses after batching.Suede color-coating steel plate aborning color coating unit has been produced, and batches after last volume, owing to occurring the flat phenomenon of collapsing of coil of strip, causes product cannot normally pack, deliver, and even entire volume is scrapped.Therefore be badly in need of taking a kind of production method, in the situation that guaranteeing that surface of steel plate coating matte effect is intact, do not produce the volume phenomenon of collapsing.
Summary of the invention
The present invention is exactly the defect for prior art, and a kind of production method of suede color-coating steel plate is provided, and it has solved suede color-coating steel plate and has easily occurred the flat phenomenon of collapsing of coil of strip.
For solving the problems of the technologies described above, the present invention by the following technical solutions: it comprises the following steps:
(1), first by the cleaning section of color coating unit, degreasing alkali cleaning and desalted water rinsing are carried out in the surface of steel plate, complete the surface clean to steel plate;
(2), then with pretreating agent, carry out two-sided pretreatment being coated with interval, controlling steel billet temperature is 90 ℃, after solidifying, forms pretreatment coating; Then with water cooled rolls, to band steel, carry out evenly cooling;
(3), steel plate is carried out to rendering, steel plate two sides is coated with to priming, controls steel billet temperature is 220-230 ℃, becomes primer coating after curing, after steel billet temperature reaches 225 ℃, carries out water quick cooling but;
(4), finally carry out essence and be coated with processing, in the front with steel, coat coating for woolen surface, back paint is coated at the back side, coating machine adopts three roller coating modes, coating roller adopts the contrary thickness that is coated with technical guarantee finish paint simultaneously, control that steel billet temperature is the highest is no more than 260 ℃, after steel billet temperature reaches 260 ℃, carry out after retarded cooling process, carrying out water quick cooling but again in stove;
(5), adopt seven-roll Abramsen machine to carry out tension straingtening to steel plate, and with pulling-straightening roller, the protrusion of surface of steel plate is polished, during tension straingtening, adopt the process of two sections of stretchings, two sections of alignings.
The good technical scheme of the present invention is: during tension straingtening, the percentage elongation that is greater than 0.8 millimeter of Shi，Gai region when the thickness of matte band steel is set as 0.2-0.3%; The percentage elongation that is less than 0.8 millimeter of Shi，Gai region when matte belt steel thickness is set as 0.1-0.2%; The interlock severity control of bending roll group is at 12-15 millimeter, and the interlock severity control of smoothing roll group is at 8-12 millimeter.
The furnace temperature heating setpoint of traditional heating technique sees the following form:
| Stove region | 1st district | 2nd district | 3rd district | 4th district | 5th district |
| Region furnace temperature | 120 | 180 | 260 | 320 | 400 |
| Region belt steel temperature | 75 | 130 | 185 | 240 | 260 |
The furnace temperature heating setpoint of heating process of the present invention sees the following form:
| Stove region | 1st district | 2nd district | 3rd district | 4th district | 5th district |
| Region furnace |
150 | 280 | 400 | 350 | 320 |
| Region |
100 | 200 | 260 | 230 | 210 |
The matte Coil Coating Products that adopts traditional handicraft to produce, because the mountain peak shape material surface of coating surface is long-pending large, easily after long high-temperature baking, there is the situation that hardening becomes fragile, elasticity reduces, thereby interlayer is difficult for combining closely and causes loose winding, tower volume phenomenon after coil of strip rolling.
The present invention adjusts the color coating heating curves of standard as shown in Figure 4, Figure 5, courageously improve the furnace temperature of leading portion, make to be with steel to reach in the short period of time after the needed steel billet temperature of resin crosslinks, reduce rapidly furnace temperature, to prevent that the mountain peak shape material of the coating surface of matte effect after transition baking, embrittlement occurs and follows the string.Therefore having solved suede color-coating steel plate easily there is the flat phenomenon of collapsing of coil of strip.The main test result of product of the present invention is as follows:
| Sequence number | Project | Expection requirement | Measured |
