Problems solved by technology

However, due to the low output of raw lacquer and the complicated lacquer coating process, the use of raw lacquer on daily necessities and handicrafts is not commonly used, and due to its unique characteristics, it is generally only used on wooden or bamboo utensils. The lacquer coating process on the surface of copper ware has been lost in today's society
[0005] Due to the existing technology, it is still impossible to paint raw lacquer on the surface

specific Embodiment 1

[0032] Specific embodiment 1: the technical solution formula that the present invention adopts is:

[0033] A large-color lacquer formula for the surface of copper ware, the prepared large-color lacquer is composed of the following raw materials and their mass percentages: raw lacquer: 65%; turpentine: 10%; colored mineral powder: 25%; and the colored After the ore powder is ground, the particle size is 600 mesh to 800 mesh. The colored ore powder is a mineral base compound, including cinnabar, silver vermilion, ocher, stone yellow, stone blue, stone green, lead powder, soot, and titanium dioxide.

[0034] Preferably, the raw lacquer is vacuum-filtered to remove impurities in the reactor.

specific Embodiment 2

[0035] Specific embodiment 2: the technical scheme paint coating process that the present invention adopts is:

[0036] Adopt a kind of varnish coating process on the copper surface of formula among the embodiment 1, it may further comprise the steps:

[0037] (1) Preliminary polishing: Preliminary polishing of the surface of the cast copperware; remove the gate and fusion joints, and use 800-1500 mesh sandpaper to polish until the surface is smooth;

[0038] (2) Copper heating: Use a liquefied gas flamethrower to heat the copper to be painted, and the heating is limited to more than 2 / 3 of the surface of the copper; the heating temperature is controlled at 800-1500°C;

[0039] (3) Cooling and spraying wax: Cool the copper ware naturally, and spray wax on the surface of the copper ware when the waste heat is cooled to room temperature; cover the part of the copper ware that needs to be painted with waterproof paper to avoid interference from wax spraying; wait for the wax to d...

Abstract

The invention discloses a formula of painted lacquer for copper ware surfaces. The painted lacquer is prepared from the following raw materials in percentage by mass: 65% of raw lacquer, 10% of turpentine and 25% of colored ore powder, wherein the grain size of the colored ore powder is 600 to 800 meshes. Simultaneously, the invention further discloses a painting process for constructing copper ware by adopting the painted lacquer. The formula and painting process of the painted lacquer for the copper ware surfaces, provided by the invention, have the aims that the copper ware surfaces are painted with the raw lacquer, and the specific texture of a utensil part is reserved; meanwhile, the single black color of the raw lacquer is changed, and the characteristics of convergence, glittering and translucence, and ancient colors and rhymes are reserved; the diversity and ornamental value of artware are improved.
