Abstract

The invention provides a vitrification agent, a preparation method thereof and a vitrification process. The vitrification agent comprises the following components in parts by weight: 5-10 parts of hexafluorozirconic acid, 15-25 parts of diamino silane, 6-15 parts of monoethanolamine borate, 1-7 parts of sodium nitrite, 3-16 parts of a pH regulator and 50-100 parts of water. According to the vitrification agent and the preparation method thereof and the vitrification process, by introducing the monoethanolamine borate, a compact and uniform vitrification film layer with excellent anti-rust performance can be generated on the surface of a workpiece, the phenomena of re-rusting, dust sticking and the like after the workpiece is subjected to vitrification treatment are effectively avoided, and the requirements before coating are met; the salt spray test time of the ceramic workpiece can be more than 500 hours, excellent adhesive force can be provided for the combination of the workpiece and various coatings, the corrosion resistance time of the workpiece is prolonged, and the impact resistance is relatively strong.

Description

technical field [0001] The invention relates to the technical field of potting procedures, in particular to a potting agent, a preparation method thereof, and a potting process. Background technique [0002] Metal workpieces usually need to be pre-treated including degreasing, rust removal, etc. before coating. In addition, a chemical conversion film needs to be formed on the surface of the metal workpiece during the pre-treatment. The conversion film has a certain anti-corrosion ability and can avoid parts. Rusting back in a short time before spraying can also increase the roughness of the surface of the part and enhance the bonding force between the coating and the substrate. The existing processes for this treatment are mainly phosphating process, pottery process, surface silanization process and organic film pretreatment process. [0003] Among them, in the existing pottery process, the metal workpiece is immersed in a potting solution containing fluorozirconic acid or ...
