The coating preparation method provided by the embodiment of the application can greatly reduce the quality inspection cost, and simultaneously improve the quality inspection efficiency and the quality of the prepared product. For the convenience of understanding the present application, a detailed description will be given of a coating preparation method provided by the present application.
Fig. 1 shows a flowchart of a coating preparation method according to an embodiment of the present application, wherein specific steps include S101 to S103.
S101, spraying a bottom layer material on the substrate, wherein the bottom layer material comprises a target material.
In a specific implementation, a base material and a target material are mixed in advance to obtain a base material, wherein the base material is a material for spraying a substrate, such as paint and the like, the target material can be a photosensitive color-changing microcapsule coating a photosensitive pigment, and can also be a mixture of methyl red, bisphenol A and p-nitrophenol and the like, and the target material does not have quality influence on the base material.
Fig. 2 shows a schematic diagram of the structure of the coating during the coating preparation process, and in connection with fig. 2, a substrate requiring a spray material, i.e., the a structure shown in fig. 2, is prepared in advance. After the primer material is obtained, the primer material is sprayed on the surface of the substrate so that the primer material can completely cover the surface of the substrate.
S102, determining whether a target bottom layer formed after the bottom layer material is solidified meets preparation conditions or not based on detection means, wherein the detection means can enable the target material to change.
After the step of spraying the primer material on the surface of the substrate is completed, the target primer, i.e., the B structure shown in fig. 2, is obtained after the primer material is cured. In the actual preparation process, the process of transferring, polishing and the like is required for the target bottom layer obtained after curing, and in the process of transferring, polishing and the like for the primer layer, the primer may be dropped, that is, the partial primer is damaged, so that the C2 structure shown in fig. 2 is formed, and of course, the situation that the primer is not dropped, that is, the C1 structure shown in fig. 2 is also present.
After the target underlayer is obtained, the target underlayer is inspected based on a detection means capable of causing a change in the target material, such as a color change, to determine whether the target underlayer satisfies a preparation condition.
In the specific implementation, the detection means corresponding to the different target materials are different, and the detailed explanation will be made below with the target materials being the photosensitive material and the temperature sensing material, respectively, but those skilled in the art should understand that the target materials are not limited to the photosensitive material and the temperature sensing material, as long as the target materials can be changed by the corresponding detection means.
As one example, in the case where the target material is a photosensitive material, the corresponding detection means is to change the light in the environment where the target underlayer is located. Optionally, the target bottom layer is placed under the target light, so that the target bottom layer generates color change, and then a first target area, which is not covered by the target bottom layer, on the substrate is determined, specifically, the area, which is not changed, is determined to be the first target area, which is not covered by the target bottom layer, on the substrate, and the first target area is the damaged area of the target bottom layer. When the target material is a photochromic microcapsule, the target light is sunlight or ultraviolet light; when the target material is a mixture of methyl red, bisphenol A and p-nitrophenol, the target light is ultraviolet light with the wavelength of 500-570 nm.
Further, comparing the first target area with a first preset area, and determining that the target bottom layer meets the preparation condition, namely that the target bottom layer is qualified in preparation, when the first target area is smaller than or equal to the first preset area or a first target proportion of the first target area to the total area of the substrate is smaller than or equal to the first preset proportion.
As another example, in the case where the target material is a temperature sensitive material, the corresponding detection means is to change the temperature of the target underlayer. Optionally, the temperature of the target underlayer is adjusted to be a target temperature, where the target temperature is a temperature that can cause the target underlayer to change color, so as to determine a second target area of the substrate that is not covered by the target underlayer, specifically, determine an area of the substrate that is not changed in color as the second target area of the substrate that is not covered by the target underlayer. When the target material is a temperature sensing material, the corresponding detection means may also be to change the temperature of the environment where the target bottom layer is located, that is, adjust the temperature of the environment where the target bottom layer is located, so as to determine the second target area, which is not covered by the target bottom layer, on the substrate.
Here, the temperature sensing material is not exemplified one by one in the embodiment of the present application, and those skilled in the art should know that a material capable of sensing temperature and color may be used as the temperature sensing material in the embodiment of the present application.
Further, comparing the second target area with a second preset area, and determining that the target bottom layer meets the preparation condition, namely that the target bottom layer is qualified in preparation, when the second target area is smaller than or equal to the second preset area or a second target proportion of the second target area to the total area of the substrate is smaller than or equal to the second preset proportion.
Referring to fig. 2, it is detected by the detection means that the target underlayer satisfies the preparation condition and is represented as a D1 structure, and the target underlayer does not satisfy the preparation condition and is represented as a D2 structure.
In the actual preparation process, the target bottom layer is one or more layers, the target materials added in the bottom layer materials of the two adjacent layers are different, namely, when the target bottom layer is detected based on the detection means, the colors displayed by the two adjacent layers of target bottom layers are different, preferably the colors displayed by the two adjacent layers of target bottom layers are larger, so that quality inspectors can easily distinguish the two layers of target bottom layers, the condition that the quality inspectors produce false detection due to the fact that the colors of the two layers of target bottom layers are similar or identical is avoided, and the purposes of improving the quality inspection efficiency and the quality of prepared products are also achieved.
It should be noted that after determining whether the target underlayer formed after curing the underlayer material meets the preparation condition, the detection means is eliminated, for example, the target underlayer is moved out from the target light, the temperature of the target underlayer is adjusted to a non-target temperature, and the target material is restored to the state before the change occurs.
And S103, spraying a surface layer material on the target bottom layer to form a coating layer under the condition that the target bottom layer meets the preparation conditions.
And under the condition that the target bottom layer meets the preparation conditions, spraying a surface layer material on the target bottom layer to further obtain an E structure shown in fig. 2, and completing the preparation of the coating.
According to the embodiment of the application, the target bottom layer is formed by using the bottom layer material comprising the target material, whether the target bottom layer formed after the bottom layer material is solidified meets the preparation condition is determined by using the detection means, and under the condition that the bottom layer meets the preparation condition, the surface layer material is sprayed on the target bottom layer to finish the preparation of the coating, so that the coating is obtained, wherein the detection means can change the target material, so that a special inspection station and a special quality inspection personnel are not required when the target bottom layer is detected, and the quality inspection cost is greatly reduced; and after the target material changes, the target bottom layer and the base material can be conveniently distinguished, so that the condition that quality inspection personnel produce false detection due to the fact that the colors of the base material and the primer layer are similar or the same is avoided, and the quality inspection efficiency and the quality of the prepared product are greatly improved.
The second aspect of the present application further provides a coating, which is prepared by using the above coating preparation method, fig. 3 shows a schematic structural diagram of the coating provided by the embodiment of the present application, and referring to fig. 3, the coating includes a substrate 1, a target underlayer 2, and a surface layer 3, where the target underlayer 2 is located between the substrate 1 and the surface layer 3. Specifically, the target underlayer 2 is covered on the surface of the substrate 1, wherein the underlayer material forming the target underlayer 2 includes a target material, which generates a certain change, such as a color change, under the detection means, and the surface layer 3 is covered on the surface of the target underlayer 2. The coating obtained by the coating preparation method has better product quality.
