Abstract
The utility model discloses a colour coated plate, belonging to the technical field of the colour coated plates used in buildings. The utility model comprises a composite layer consisting of a front topcoat layer (1), a front primer layer (2), a substrate layer (3) and a back primer layer (4), wherein, the structure of the composite layer is that the front topcoat layer (1), the front primer layer (2), the substrate layer (3) and the back primer layer (4) are arranged orderly, and the coating material of the front primer layer (2) is different from that of the back primer layer (4). Compared with the prior art, the utility model has better elasticity and toughness, i.e. excellent T bending performance, and also has better wear resistance simultaneously.
Description
Technical field:
The utility model belongs to this technical field of Coil Coating Products, belongs to this technical field of Coil Coating Products for building especially.
Background technology:
Coil Coating Products is a kind of construction material that scribbles coating at the front and the back side of substrate, therefore coating performance is the key that guarantees product quality, in processing and application process, the product coating performance is had different specific requirements: face-coating will have good ornamental, durability, processability; Back coating will have higher workhardness, excellent adhesive property etc.Coating performance is except that being subjected to finish paint influences, and priming paint also has very important effect.Common building Coil Coating Products finish paint mostly is the polyester system, and paint base system mainly contains polyurethane and epoxy.Polyurethane primer has elasticity and toughness preferably, and promptly You Yi T bends performance, but hardness of paint film is lower, and anti-wear performance is slightly poor, and is not strong with the bonding adaptability of processing auxiliary material; Epoxy primer coated adhesive performance is good, and hardness is higher, has wearability preferably, bends slightly inferior properties but the pliability of paint film is T.Because two kinds of solidifying priming paint technologies are variant, in traditional Coil Coating Products production process, for the ease of technology controlling and process and easy to operate, priming paint positive, that the back side applies all is same system, promptly just, the back side is used polyurethane simultaneously or is used epoxy coating simultaneously, therefore be unfavorable for giving full play to the advantage function of different system priming paint, the integrated application performance is produced comparatively passive influence.
The utility model content
Problem to be solved in the utility model provides a kind of Coil Coating Products that can give full play to different system priming paint.
The technical scheme of the utility model technical solution problem is: a kind of Coil Coating Products, comprise the composite bed that front finish paint layer, front prime coat, substrate layer, back side prime coat are formed, lamination layer structure is that front finish paint layer, front prime coat, substrate layer, back side prime coat are arranged in order, and the front prime coat is different with the coating material of back side prime coat.
Preferred front prime coat material is a polyurethane coating, and the material of back side priming paint is an epoxy coating.
Used substrate is heat zinc coating plate, galvanizing aluminium alloy plate, hot-dip coating aluminium-zinc alloy plate, zn-fe alloy coating plate etc., can select for use arbitrarily according to user's request.Generally, preferred heat zinc coating plate is a substrate.
The utility model is by adjusting polyurethane and the dicyandiamide solution of epoxy primer and the prescription of curing agent component, realize the unification of the curing performances such as solvent evaporates speed, cross-linking reaction temperature of two kinds of system priming paint, thus make that the coating of different systems all can be firm attached on the substrate.
The utility model compared with prior art has elasticity and toughness preferably, and promptly the curved performance of You Yi T also has wearability preferably simultaneously.
Description of drawings:
Fig. 1 is the structural representation of an optimal way of the utility model;
In diagram, front finish paint layer 1, front prime coat 2, substrate layer 3, back side prime coat 4.
The specific embodiment:
Embodiment 1: as shown in Figure 1, the front of hot dip galvanizing substrate layer 3 scribbles polyurethane primer layer 2, the back side scribbles epoxy resin primer layer 4, solidifying front finish paint layer 1 in the other one side that polyurethane primer layer 2 and hot dip galvanizing substrate layer 3 link, the material of this coating can be selected according to requirement of client, as polyester, silicon modification of (co) polyesters, PVDF etc.
Embodiment 2: except that front prime coat 2 and back side prime coat 4 are the epoxy resin, all the other are identical with embodiment 1.
Embodiment 3: except that front prime coat 2 and back side prime coat 4 are the polyurethane resin, all the other are identical with embodiment 1
Hardness detects by ASTM D3363 standard.
T is curved to be detected by ASTM D4145 standard.
Adhesive property detection method: take by weighing A glue, B glue two components by a certain percentage, mix well and be applied over the back coating surface of two colored steels rapidly, the pressure of compound after-applied about 2Kg solidifies and observes the adhesion condition of foam at coating surface after 3 hours, and effectively bond area 〉=80% is qualified.
Salt fog resistance detects by ASTM B117 standard.
| Hardness | T is curved | Adhesive property % | Salt fog resistance | |||||
| Positive | The back side | Positive | The back side | Positive | The back side | Positive | The back side | |
| Embodiment 1 | F | 2H | 2T | 3T | 100 | 3T | 2000 | 500 |
| Embodiment 2 | H | 2H | 3T | 3T | 100 | 3T | 2000 | 500 |
| Embodiment 3 | F | H | 2T | 3T | 60 | 3T | 2000 | 300 |
Find out by table 1, behind enforcement the utility model (embodiment 1), the workhardness of back coating, adhesive property, decay resistance is better than embodiment 3, the curved performance of the processing T of face-coating is better than embodiment 2, just, the coating advantage performance at the back side embodied in identical product, improved product greatly and used the adaptability of processing.
Claims (2)
