Description
Technical Field
The invention belongs to the technical field of coating, and particularly relates to a water-based sealant coating and a preparation method thereof.
Background
The high manganese steel frog is alloy steel with high manganese and carbon contents, has high strength and good impact toughness, and can be quickly hardened under the action of impact load after heat treatment, so that the surface has good smoothness and wear resistance. The high manganese steel frog products need to be coated with a layer of protective varnish before leaving a factory to ensure that the high manganese steel frog products are not corroded and have good appearance, and the coating used for the high manganese steel frog products on the market at present is a solvent-based coating basically, contains a large amount of volatile organic compounds (VOC for short), has large influence on the environment and human health, and has large risks in operation and storage.
Based on the problems caused by the solvent-based coating for the high manganese steel frog product, the high manganese steel frog product starts to use the water-based coating, the water-based coating takes water as a diluent, the volatile organic compound content is less, the cleaning is easy, the influence on the environment and the human health is small, and the operation and the storage are safe. However, in the process of using the water-based paint for the high manganese steel frog product, the high manganese steel frog has a whitish mark locally, the white matter disappears in the process of brushing the water-based paint, but the white mark appears again after the water-based paint film is dried, and the special water-based varnish for the high manganese steel frog can not cover the mark, so that the high manganese steel frog product after painting is directly unattractive.
The substance for generating the whitening mark is cutting fluid (modified water glass), mainly contains silicon dioxide and sodium oxide, is easy to dissolve in water, and has poor water resistance. The high manganese steel frog casting needs to be separated from the casting system by an electric spark cutting technology, and cutting fluid (modified water glass) is used in the process. Since spark is splashed in the electric spark cutting process, cutting liquid is splashed to other parts, and therefore white marks appear at and around the cutting part. The water paint takes water as a diluent, when the water paint is brushed, cutting fluid is dissolved in the water paint, white marks disappear, and after the water is evaporated, the remained substances form a white mark to appear on the surface of the frog casting.
Aiming at the characteristic that the modified water glass is easy to dissolve in water, the modified water glass is erased after being sprayed with water on the surface of a casting with white marks, but the modified water glass after being dissolved in water is colorless and transparent, so that whether the modified water glass is completely removed or not is difficult to know, and the erasing difficulty is high at complex parts such as slits. Further analysis shows that the solution of the modified water glass after being dissolved in water is alkaline, and in the process of water evaporation and drying, the high manganese steel frog casting is in an alkaline environment, so that the high manganese steel frog casting is corroded to a certain degree. The occurrence of the phenomenon seriously hinders the popularization and application of the water-based varnish.
In order to better eliminate the influence of the modified water glass on the application of the water-based paint on the surface of the manganese fork casting, a sealing agent is developed, and the modified water glass is dissolved and coated in a sealing agent coating by utilizing a physical sealing principle, so that the modified water glass is well isolated from water in subsequent water-based varnish.

The preparation method comprises the following steps: mixing cosolvent isopropanol and water-based alkyd resin, stirring the mixed solution for 10-15 minutes by setting a rotating speed of 500-600 r/min through a stirrer, uniformly stirring, sequentially adding a defoaming agent TEGO 810W, a base material wetting agent BYK346, a thickening agent OMG 0434 and a water-based drier chemical WD016, stirring for 10-15 minutes, adding a pH regulator N, N-dimethylethanolamine, finally adding cosolvent D40 solvent oil to adjust the construction viscosity, and filtering and packaging through 200-mesh filter cloth.
The prepared aqueous sealant coating was sprayed on a test board which was degreased and rust-removed, and after maintaining for one week in a constant temperature and humidity chamber, the paint film was subjected to a performance test, and the results are shown in table 3 below:
TABLE 3
The water-based sealant coating disclosed by the invention has good sealing property on residual manganese fork casting cutting fluid, and meanwhile, a paint film prepared from the sealant has excellent performances such as impact property, gloss, adhesive force, water resistance and the like, and by matching with the water-based varnish for the high manganese steel frog, the VOC (volatile organic compound) in the whole construction process is reduced, and the water-based varnish has great significance in promoting the water-based varnish to be used in the field of the high manganese steel frog.
The foregoing description of specific embodiments of the present invention has been presented. It is to be understood that the present invention is not limited to the specific embodiments described above, and that various changes or modifications may be made by one skilled in the art within the scope of the appended claims without affecting the spirit of the invention. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict.
