Embodiment 1

[0026] A kind of preparation method of earthenware lacquerware is characterized in that, comprises the following steps:

[0027] (1) For the body of the pottery body, according to the ceramic preparation process, the body is prepared with coarse clay;

[0028] (2) Grinding, use No. 120 and No. 320 sandpaper to grind clockwise on the surface of the body to make the surface rough and improve the adhesion of raw lacquer on the surface. The grinding time is 30 minutes, and the grinding speed is 300 rpm;

[0029] (3) To paint raw lacquer, use a hairbrush to brush the raw varnish on part or all of the surface of the embryo body that needs to be decorated with beard paint 5 times, so that the bottom tire of the green body can fully absorb the paint liquid, so that the green body will remain intact during the subsequent painting process. The bottom tire will not absorb and damage the paint;

[0030] (4) Baking the varnish, put it into the kiln and bake at 130°C for 40-45min, the raw ...

Abstract

The invention discloses a manufacturing method of a ceramic substrate lacquerware. The method comprises the following steps of (1) manufacturing a ceramic substrate green body; (2) polishing; (3) coating a raw lacquer; (4) baking a varnish; (5) coating colored paint; (6) carrying out graining modification on a surface; (7) grinding: a, coating a first black refined Chinese lacquer; b, grinding paint; (8) brightening; and (9) wiping. In the invention, a problem that the raw lacquer is easy to fall off when be coated on a ceramic surface is solved. The raw lacquer can be firmly attached to the surface of a ceramic substrate through a scientific baking process, preferably baking is performed at a temperature of 130 DEG C for 40-45 min, and a bright color of the raw lacquer is still kept. Crafts ceramics and arts and crafts are ingeniously combined, a novel and unique ceramic utensil which is not easy to damage, is resistant to a high temperature and moisture, and is easy to store is manufactured, gloss is natural, a texture is clear, soft and beautiful, transparency and brightness are achieved, an artistic ornamental value and a collection value are achieved too, and the manufacturingmethod is scientific in procedure design and is practical.

Description

technical field [0001] The invention relates to the technical field of ceramic surface decoration, in particular to a smooth-surfaced ceramic product partially decorated with raw lacquer and a manufacturing process thereof. Background technique [0002] Lacquerware and porcelain are the treasures of Chinese handicrafts. The use of lacquer has a history of more than 700 years in my country. Lacquer paintings use natural lacquer as the main material. In addition to lacquer, there are gold, silver, lead, tin and eggshells. , shells, stone chips, wood chips, etc. It is not only a handicraft, but also a practical decoration, and has become a form of expression for wall decorations, screens and murals.
