Embodiment 1

[0012] Embodiment 1, a kind of preparation technology of phospho-silicate enamel, it is made by following weight percentage proportioning, P 2 o 5 : 22%, SiO 2 : 32%, B 2 o 3 : 12%, Al 2 o 3 : 5%, TiO 2 : 2%, ZrO 2 : 2%, Na 2 O: 8%, K 2 O: 4%, ZnO: 4%, CoO: 1%, NiO: 2%, CaO: 3%, MgO: 3%.

[0013] The specific production method is:

[0014] (1) Ingredients and high-temperature melting: The above-mentioned various raw material powders are accurately weighed according to the proportion, mixed evenly, sent to a high-temperature furnace, and melted at 1350-1500°C to obtain a uniformly composed enamel melt, which is quickly cooled after being taken out. A homogeneous enamel frit is obtained.

[0015] (2) Preparation of enamel dry powder or glaze slurry: Mix the above-mentioned homogeneous enamel frit with the usual grinding materials in a certain proportion, and perform dry or wet method in a ball mill or other fast grinding equipment (add a certain amount of water) Grin...

Abstract

The invention provides a preparation technology of phosphosilicate enamel, which comprises the raw materials based on weight percentage as follows: 15%-30% of P205, 20%-35% of SiO2, 8%-15% of B2O3, 5%-12% of Al2O3, 1%-4% of TiO2, 1%-5% of ZrO2, 0-1% of CoO, 0-2% of NiO, 5%-10% of Na2O, 2%-6% of K2O, 0-4% of 'ZnO, 2%-6% of CaO and 1%-5% of MaO. The preparation technology comprises the steps of dosing, founding under a high temperature, preparing enamel dried powder or glazeslip, coating the enamel, and sintering. After the phosphosilicate enamel which is prepared by the method is used, the abrasion resistance and the shock resistance of the enamel are effectively improved, and the enamel with better performances is developed for the industrial application of the enamel which is taken as an abrasion resistant structure, a building decoration material, and the like.

Description

technical field [0001] The invention relates to a preparation technology of phospho-silicate enamel. Background technique [0002] As an excellent wear-resistant and corrosion-resistant material, enamel is increasingly favored by the fields of industry and architectural decoration. Enamel has been used more and more widely as wear-resistant structural parts and decorative materials for subway interiors and building exteriors. Therefore, the wear resistance and external impact resistance of industrial enamel are the key to its wider application. [0003] In recent years, there are mainly two methods to improve the wear resistance and impact resistance of enamel products. One is to add some high hardness materials, such as alumina, zirconia, etc., and disperse them in the enamel glaze with hard particles. , to achieve the purpose of improving the wear resistance and impact resistance through particle strengthening; the second is to adjust the composition of the enamel glaze a...
