Abstract
The invention relates to a production method of a hot-applied film color-coated board. The production method comprises the following steps of: cleaning a substrate; performing the chromium-free passivation on the substrate; firstly coating the substrate after drying, namely, coating the rear coatings; after curing the rear coatings in the step (3), performing water-cooling on the substrate; gluing the substrate on a precise coating B, namely, coating an adhesive, and activating the adhesive; thermally coating a composite film on the substrate; then water-cooling and cold-applying the film; and checking the obtained hot-applied film color-coated board, then reeling. The production method fills the technical gap in the production of the hot-applied film color-coated board in high speed (more than 30 m/min) in our country, and plays a role of improving the capacity and reducing the cost; and not only the function of the production line device can be completely developed, but also the economic benefit can be obviously improved due to the batch production.
Description
Technical field
The present invention relates to a kind of production method of hot-applied film color-coated board.
Background technology
At present, both at home and abroad to the demand of thermosticking film colored steel product in cumulative year after year.And the production capacity of thermosticking film production line is low, and main cause is that domestic thermosticking film line speed is low, substantially all at 6-20m/min, directly affects production efficiency.How improving thermosticking film production linear velocity is the problem that industry is paid special attention to.The linear velocity that inventor unit one belongs to adopts is 30m/min, and exploitation thermosticking film colored steel is not only a progress of our factory's new product work, has filled up especially the technological gap of high-speed line production thermosticking film colored steel.
Summary of the invention
The object of the present invention is to provide a kind of production method of hot-applied film color-coated board, when improving speed of production, guarantee the quality of production of Coil Coating Products.
Concrete technical scheme is as follows:
A kind of production method of hot-applied film color-coated board, adopt following steps:
(1) substrate is cleaned;
(2) substrate is carried out chromium-free deactivation;
(3) substrate is carried out rendering after drying, i.e. the coated back surface paint;
(4) treat that the back paint in step (3) solidifies, and carries out water-cooled to substrate;
(5) be coated with on B in essence substrate is carried out gluing, namely apply adhesive, and carry out the glue activation;
(6) heat is covered composite membrane on substrate;
(7) carry out water-cooled and cold pad pasting after overlay film;
(8) hot-applied film color-coated board that obtains is tested, then batch.
Further, before step (1) is cleaned substrate, substrate is carried out prerinse.
Further, carry out in prime oven described step (3) and (4).
Further, described step (5) is carried out in roll coater and/or finish oven.
Further, described step (6) is carried out on laminator.
Further, the substrate in described step (1) is selected the softer cold-reduced sheet of material.
Further, the hot overlay film in described step (6) is selected the PET+PVC composite membrane.
Further, the METAL HEATING PROCESS peak value PMT180 in described step (6)～220 ℃, preferred 200 ℃ of left and right.
Further, the pad pasting roller of selecting in described laminator is upper steel rider and lower rubber roller.
Further, the viscosity of the glue in described step (5) or adhesive is controlled at the 20s left and right.
Further, line speed is controlled at 30m/min; When producing hot overlay film product with cold-reduced sheet, must suitably reduce furnace temperature, simultaneously shrend be sprayed pressure and reduce; Before producing, all roll surfaces are cleaned wiping; Cleared up overlay film roller booty before overlay film, adjusted overlay film pressure, pad pasting tension force is cleaned out the glue on roller; When producing hot overlay film product with cold-reduced sheet, must suitably adjust process for cooling; Film place on thermosticking film is also increased closed installation.
Compare with present prior art, the present invention has filled up the technological gap of China's high-speed production thermosticking film colored steel, to improving production capacity, reducing costs and play certain progradation.The function of apparatus for production line can not only be given full play to, in case the more important thing is batch production, economic benefit can be significantly promoted.
Description of drawings
Fig. 1 is critical section technological design figure of the present invention (roller coat-pad pasting-essence is coated with shrend)
Annotate: what squeeze in batea is glue.
The specific embodiment
The below describes the present invention with reference to the accompanying drawings, and it is a kind of preferred embodiment in numerous embodiments of the present invention.
With reference to accompanying drawing 1:
1) the product processes flow process is as follows:
Substrate → prerinse → cleaning → chromium-free deactivation → oven dry → rendering back paint → back of the body paint curing → water-cooled → gluing (essence is coated with B) → glue activation → heat is covered composite membrane → water-cooled → (cold pad pasting) → check → batch.
When 2) producing debugging, rendering coated back surface paint, essence is coated with B and applies adhesive, and linear velocity is controlled at 30m/min.Substrate adopts the partially soft cold-reduced sheet of material, and what hot overlay film was selected is the PET+PVC composite membrane.Glue viscosity is controlled at the 20s left and right.PMT is controlled at 200 ℃ of left and right.
3) before production, all roll surfaces (all rollers on the main roller such as rendering shrend squeeze roll, 5# deviation rectification roller, 8# slewing rollers and 4# idler roller and line) are cleaned wiping, can reduce and eliminate the defectives such as particle, bubble like this.
4) cleared up overlay film roller booty before overlay film, adjusted overlay film pressure (70N), pad pasting tension force (20N) is cleaned out the glue on roller.
5) the pad pasting roller of selecting is upper steel rider, lower rubber roller.From surface quality, respond well.Directly eliminated the fold phenomenon, hot overlay film firm pasting, smooth.
6) for eliminating substrate through producing the phenomenon of middle part, back side folding line after curing oven, when producing hot overlay film product with cold-reduced sheet, must suitably adjust process for cooling, thereby obtain good pad pasting effect.
7) the thermosticking film product is very high to the environmental sanitation requirement of production line, and the place that floating ash much may occur all might cause dust granule.Therefore our factory carries out totally-enclosed transformation to the verifying bench that 2# produces unit (production line of thermosticking film), and film place on thermosticking film has also been increased closed installation.In addition, steel band has one section to be exposed to air from prime oven to finish oven, and for avoiding dust adhesion, all block with curtain on both sides.
The above is exemplarily described the present invention by reference to the accompanying drawings; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as the various improvement of having adopted method design of the present invention and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection scope of the present invention.
