A kind of Coil Coating Products of writing
Technical field
The utility model relates to a kind of Coil Coating Products of writing as teaching and office usefulness.
Background technology
That existing blackboard exists is easily reflective, color and luster is dim, adhesive force and pliability is poor, not scrubbing resistance, surperficial paint film easily chap, efflorescence, shock resistance is poor, defectives such as ageing resistance is weak, therefore blackboard in use can occur writing not smooth, the problem that service life is short, and the cost of traditional blackboard is higher.For addressing the above problem, the applicant has developed a kind of Coil Coating Products of writing, and this writes the substitute that Coil Coating Products can be used as teaching and office usefulness blackboard.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of fluent writing, long service life and the lower-cost Coil Coating Products of writing.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of Coil Coating Products of writing is characterized in that it comprises a substrate, and the surface-coated of substrate has immersion coating, wherein is coated with green plate paint on the immersion coating of substrate front side.
As the utility model improvement of the technical scheme, be coated with priming paint on the immersion coating of described substrate back, be coated with diaphragm on the green plate paint.
Substrate of the present utility model can adopt steel plate to make.
The beneficial effects of the utility model are: substrate front side of the present utility model singly is coated with (only being coated with one deck finish paint) special green plate paint, solidify the back free from extraneous odour, color presents blackish green, be difficult for reflective, feature performance benefit: pencil hardness can reach 4H, anti-scratch performance is good, and impact test and organic solvent-resistant test reach tame electroplax standard.This product technology is simple, and the output height is cheap.Can replace teaching to use fluent writing, long service life with blackboard.Owing to adopt the mode that singly is coated with, the paint consumption is few, has saved cost under the situation that guarantees good function of use.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1, the disclosed a kind of Coil Coating Products of writing of the utility model comprises a substrate 1, this substrate 1 can be made with steel plate, also can adopt other hard material to make, immersion coating 2 be arranged, wherein be coated with green plate paint 3 on the immersion coating 2 in substrate 1 front in the surface-coated of substrate 1, green plate paint 3 solidifies the back free from extraneous odour, color presents blackish green, is difficult for reflectively, and feature performance benefit: pencil hardness can reach 4H, anti-scratch performance is good, and impact test and organic solvent-resistant test reach tame electroplax standard.
As shown in the figure, be coated with priming paint 4 on the immersion coating 2 at substrate 1 back side, be coated with diaphragm 5 on the green plate paint 3, manufacture craft of the present utility model is simple, and the output height is cheap.Can replace teaching to use fluent writing, long service life with blackboard.Owing to adopt the mode that singly is coated with, the paint consumption is few, has saved cost under the situation that guarantees good function of use.
