Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "open," "upper," "middle," "length," "inner," and the like are used in an orientation or positional relationship for convenience in describing the present invention and for simplicity of description, and do not indicate or imply that the referenced components or elements must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
Referring to fig. 1, the present invention is a three-dimensional touch steel plate panel, including: a steel plate substrate 11, a back paint layer 12, a primer layer 13 and a finish paint layer 14; a back paint layer 12 is arranged on the back of the steel plate substrate 11; the front surface of the steel plate substrate 11 is provided with a primer layer 13 and a finish paint layer 14 in sequence from inside to outside.
Specifically, the topcoat layer 14 includes ethylene diamine and metallic sodium; the mass fraction of the ethylenediamine in the finish paint layer 14 is 3-5%; the mass fraction of the metal sodium in the finish paint layer 14 is 8-10%; the steel sheet substrate 11 was a hot-dip galvanized steel sheet having a thickness of 0.5 mm.
Referring to fig. 2, a manufacturing process of a three-dimensional touch steel plate panel includes the following steps:
a00: selecting a hot-dip galvanized steel plate with the thickness of 0.5mm as a steel plate substrate 11;
a01: sequentially performing degreasing treatment, washing treatment and passivation treatment on the steel plate substrate 11;
a02: coating a back paint layer 12 on the back surface of the steel plate substrate 11 in a roller way, and completely curing the back paint layer 12 through a heat drying channel at 230 ℃; specifically, the lowest temperature of the drying tunnel is not less than 170 degrees, the highest temperature is not more than 230 degrees, and the temperature in the drying tunnel is higher and higher, and the drying process in the drying tunnel in the steps A03 and A04 is also the same;
a03: coating the primer layer 13 on the front surface of the steel plate substrate 11 by roller, and completely curing the primer layer 13 through a hot baking channel at 230 ℃ and 170 ℃;
a04: coating a finish paint layer 14 on the outer surface of the primer layer 13 of the steel plate substrate 11 in a rolling way, and completely curing the finish paint layer 14 through a 170-230 ℃ hot baking channel;
in addition, the main material in the top coat layer 14 is polyester resin, and contains ethylenediamine and metal sodium, and the mass fractions of ethylenediamine and metal sodium are 3% and 10%, respectively. After finishing the roller coating of the finish paint, the steel plate substrate 11 passes through a 170-230 ℃ baking channel, at this time, the metal sodium is changed into a liquid state (the melting point of the metal sodium is 98 ℃), and the liquid metal sodium slowly migrates to the surface of the paint layer, so that the purposes of improving the brightness and surface texture of the finish paint layer 14 are achieved. The boiling point of the ethylenediamine is about 117 ℃, in the hot drying channel, the ethylenediamine is heated and then is converted into a gas state from a liquid state, bubbles are dissociated to the surface of the finish paint layer 14, the bubbles are exploded due to large difference of internal pressure and external pressure, and the original smooth structure of the finish paint layer 14 is destroyed by force generated by the bubble explosion, so that the finish paint layer 14 is uneven, and the PCM plate presents random three-dimensional texture. And the steel plate substrate 11 is discharged from the hot drying channel, cooled by an air cooler and rolled into a PCM plate finished product.
According to the invention, the metallic sodium and the ethylenediamine are added into the finish paint layer 14, only the temperature needs to be adjusted, and through the change of the physical states of the metallic sodium and the ethylenediamine, the three-dimensional random texture can be realized on the surface of the steel plate substrate 11, and the surface brightness of the plate can be improved; in addition, the manufacturing process is simple, the original PCM plate production process is not changed, no additional equipment investment is needed, the efficiency is high, and the cost is low; meanwhile, the panel breaks through the technical bottleneck that the surface of the PCM plate is smooth and flat, greatly improves the texture and the grade of the product, and obviously reduces the surface quality defect rate of the PCM plate during molding.
