Abstract

The invention relates to a preparation method of a golden yellow ceramic paint for subway stations. The preparation method comprises the following steps: (1) preparing a functional polysiloxane prepolymer; (2) preparing modified conductive functional power bodies; (3) preparing the golden yellow ceramic paint, under a stirring condition, adding the functional polysiloxane prepolymer, a solvent, the modified conductive functional powder bodies and an addition agent in proportion by weight for mixing, and eliminating bubbles by a supersonic antifoaming method so as to obtain the desired golden ceramic paint for the subway stations. According to the invention, the modified conductive powder bodies are acetified and adsorbed and fixed by carbon black, so that the surface of the carbon black is coated with copper ions; besides, the color of the copper is golden yellow, by an adsorbing and reducing method, not only the electric conductivity of single carbon black can be improved, but also the traditional conductive paint can be enabled to be transformed into golden yellow from single black, as for simple metal addition, the addition level of metal can be reduced, and the high unification of the electric conductivity and the color of the paint is realized.

Description

【Technical field】 [0001] The invention relates to the technical field of ceramic coatings, in particular to a method for preparing golden yellow ceramic coatings used in subway stations. 【Background technique】 [0002] Traffic congestion has appeared in major cities in China since the 1990s, and the solution at that time was to build roads. However, under the extraordinary speed of development, road construction alone cannot solve the problem of traffic congestion. Therefore, the state proposes to vigorously develop public transportation, especially the development of urban rail transit to solve the problem of urban congestion. Major cities such as Beijing, Shanghai, and Guangzhou have formulated large-scale rail transit construction plans, and other domestic cities have also entered the peak period of rail development. Currently, Shanghai has 13 lines with a total mileage of 500 kilometers; Beijing has 14 lines with a total mileage of 336 kilometers; Guangzhou has 8 lines...
