Product by spraying with high molecular materials by dry method and glazing at low temperature and production process thereof

Abstract

The invention provides a product by spraying with high molecular materials by a dry method and glazing at low temperature and a production process thereof. The product is obtained by spraying with glazing powder by a dry method and glazing at low temperature on surface of a balled iron blank. The glazing powder is made from the following parts of raw materials by weight: substrate materials: 30-50 parts of resin, 2-8 parts of silicon dioxide and 10-20 parts of titanium dioxide; auxiliary materials: 2-9 parts of stainless steel powder, 3-8 parts of iron powder, 2-7 parts of calcium carbonate and 5-12 parts of magnesium carbonate; and additives: 0.5-3.5 parts of a curing accelerator, 1-3 parts of a leveling agent, 1-3 parts of a colorant, 1-3 parts of a luster-enhancing agent and 1-3 parts of an anticorrdant. The production process thereof comprises the following steps: fabricating the balled iron blank, pickling, degreasing, surface conditioning, phosphating, spraying by the dry method, pyrographing, spraying with fluorescent liquid and adding a steel ring to obtain a finished product. The sintering temperature of the production process is 160-200 DEG C, porcelain surface of the product is flat and smooth and is bright like a mirror, and rich in designs and colors; avoids porcelain shedding during collision and beating, and has long service life.

Description

technical field [0001] The invention relates to a production process for spraying fixed glaze on the surface of metal products, in particular to a product and a production process for spraying low-temperature fixed glaze on the surface of a polymer material. Products and production processes that are made and attached to the metal surface glaze. Background technique [0002] Among the currently disclosed technologies, the enamel industry mostly adopts a wet enamelling process. Wet enamelling is prone to surface defects such as pinholes, air bubbles, cracks or deformation, shrinkage of glaze, and porcelain dropouts during enamelling and post-cooling. When fired at high temperature, the pattern is easy to change color, not bright, the product qualification rate is low, and the raw materials in the enamelling process cannot be recycled, which is easy to cause environmental pollution. Chinese patent 200510094501.1 discloses "a low-temperature electrostatic enamel powder for st...

Problems solved by technology

Compared with the traditional process, its invention overcomes the defects of the wet enamelling process to a certain extent, but the firing temperature still needs to be 700 ° C ~ 740 ° C
