A color-changing enamel processing method applied to metal surfaces

Abstract

The invention discloses a color-changing enamel processing method applied to a metal surface. The steps include: making a pattern groove on the surface of a metal body; 10‑14wt%, phosphorus 8‑12wt%, organic pigment 20‑30wt%, binder 20‑30wt% mixed to make enamel glaze powder; add thermosensitive coloring material and color filler required by the product into the enamel glaze powder and adjust Forming enamel paste; the metal embryo body pattern grooves are filled with enamel paste many times and baked for many times until the enamel completely fills the precious gold embryo body grooves. The invention promotes the release of the concentrated internal stress of the enamel glaze during the molding process through multiple fillings and baking and cooling, and realizes a simple production process through the step-by-step attachment of the enamel, so that the enamel glaze is not easy to appear after cooling Detachment due to cracks or production sandwiched layers.

Description

Technical field [0001] The present invention relates to the field of 珐 handicrafts, and more particularly to a discoloration processing method applied to a metal surface. Background technique [0002] The existing enamel products are used in glass products, ceramic products, and enamel will be pulverized to ground glaze, apply to glass products after processes, after the surface of ceramics, dry, burna, etc. The resulting composite handicraft. [0003] The composition of the glaze mainly includes raw materials such as quartz, pulp, boron sand, fluorine, etc., and is added to a powder shape, and then bold into a mixture of silicic acid compounds. [0004] The difference between the metal color material and the quartz high melting point of silica as the main ingredient, the difference in expansion coefficients between the ceramic articles, can be completely attached to the glass, the ceramic product surface after direct firing, showing a bright color However, when the conventional ...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is that, aiming at the defects of the prior art, the present invention provides a color-changing enamel processing method applied to the metal surface, by increasing the adhesion between the enamel glaze and the metal surface, and performing multiple filling and baking Make the enamel gradually shape and release the internal stress, aiming to solve the problem of surface cracking when the enamel pigment in the prior art is directly applied to different metals, so as to improve the yield rate of the color-changing enamel in the mass production process
