Detailed Description
The present invention is described in detail below with reference to fig. 1.
A silica gel dipping plastic process comprises the following steps:
s1, pouring the semisolid ceramic silica gel into a container;
s2, heating the metal piece;
and S3, placing the heated metal piece in a container, and enabling the ceramic silica gel to be adsorbed on the surface of the metal piece.
Specifically, in step S2, the metal piece is subjected to a heating process, where the heating temperature of the metal piece is positively correlated to the thickness of the ceramic silica gel to be attached to the surface of the metal piece.
That is, the higher the temperature of the heat treatment, the thicker the thickness of the ceramic silica gel adsorbed on the surface of the metal material. This application lets ceramic silica gel adsorb in the surface of metalwork automatically through heating the metalwork, and the ceramic silica gel layer of formation is more even, the surface shape of metal piece of laminating more. Specifically, the metal piece is a special-shaped metal piece. Because the position that the power part of different electric motor cars needs the electricity to be connected is inequality, and the shape of the metalwork that corresponds also is the shape of irregularity, consequently adopts the adsorbed mode of heating to let ceramic silica gel more laminate the surface of metal spare, prevents to appear omitting the place of coating.
In this embodiment, after step S3, the method further includes the following steps: and S4, taking the metal piece adsorbed with the ceramic silica gel out of the container, and baking the metal piece. After the adsorption is finished, the ceramic silica gel layer on the surface of the metal piece is softer, so that the metal piece is baked, and the ceramic silica gel layer can be hardened. Specifically, the temperature of the baking treatment is 150 ℃ to 250 ℃. Such high temperatures may further improve the surface hardness of the ceramic silica gel layer. The baking treatment adopts an oven. This ensures that the temperature of the baking process is continuously high.
In this embodiment, after step S4, the method further includes the following steps: and S5, performing high-temperature curing treatment on the baked metal piece. Therefore, the ceramic silica gel layer on the surface of the metal piece can be subjected to high-temperature ceramic treatment, the ceramic metal piece can resist the high temperature of 1200-1800 ℃, the combustion is prevented, and the use safety of the metal piece is further improved. The temperature of the high-temperature curing treatment is 700-800 ℃. The quality of ceramic silica gel layer ceramic can be ensured by the high temperature. The high-temperature curing treatment adopts a vacuum high-temperature furnace. This ensures that the temperature at which curing takes place is continuously high.
Although the present invention has been described with reference to the above preferred embodiments, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
