Antiknock enamel static power and preparation method thereof

Abstract

The invention discloses an antiknock enamel static power and a preparation method thereof. The method comprises the following steps: preparing the following raw materials by weight percent: 91-95% of titanium / barium-containing enamel ceramic glaze, 1-3% of enamel pigment, 4-6% of quartz powder, 0.1-0.12% of silane / siloxane concentrated oil and 0.13-0.15% of polymethyldiphenylsiloxane, wherein isocaprylic acid is 7-7.5% silane / siloxane concentrated oil; putting the titanium / barium-containing enamel ceramic glaze, enamel pigment, quartz powder, silane / siloxane concentrated oil and isocaprylic acid into a dry ball mill for grinding, till the ground powder particle D50 is 40-45um; adding polymethyldiphenylsiloxane into the mixed powder and grinding till D50 is 16-18um; putting the acquired material into a heating stirrer at 120 DEG C, stirring and fully homogenizing the organic matter on the powder surface; sieving the powder with 200-mesh sieve, thereby acquiring the product. After the antiknock enamel static power provided by the invention is coated on an enameled pressed steel with porcelain exploding trend and is sintered, the enamelware is free from fish-scaling.

Description

technical field [0001] The invention belongs to the technical field of electrostatic enamel dry powder spraying, and specifically relates to an anti-explosion enamel which is used for electrostatic dry powder spraying of enamel products and fired on enamel steel plates with a tendency to explode. Electrostatic powder and its preparation. Background technique [0002] After the existing electrostatic enamel powder at home and abroad is sprayed on the enamel steel plate with enamel and fired, the enamel products made will produce flaky enamel like fish scales. This defect is caused by firing and cooling to room temperature for a period of time. produce. Every year, the scale-like explosion of porcelain causes huge economic losses to enamel manufacturers. This is the most troublesome problem facing the world's enamel industry, and it is also a difficult problem that has not been solved for quite a while in the field of enamel technology through various efforts. .

AI Technical Summary

Problems solved by technology

Many enamel processing manufacturers process incoming materials and have no right to choose steel plates at all, which makes it easier to cause scale explosion of enamel products.
