Problems solved by technology

[0005] The stability of traditional enamel in the atmosphere is very poor. The resistivity of traditional enamel drops rapidly one hour after electrostatic spraying, so it cannot be used for electrostatic dry powder spraying. It must be insulated. When its resistivity reaches a fairly high value , can be used for electrostatic dry powder coating

Embodiment 1

[0038] See figure 1 , the preparation method of electrostatic enamel powder in the present embodiment comprises the following steps:

[0039] 1. Prepare raw materials according to the following ingredients and weight ratio:

[0040] A. Quartz 45%;

[0041] B. Borax 18%;

[0042] C. Adhesive 5%;

[0043] D. Flux 32%;

[0044] The flux described therein includes: albite feldspar, potassium feldspar, calcium fluoride, sodium fluorosilicate, and the weight ratio of each component in the enamel powder raw material is: albite feldspar is 8%; potassium feldspar 4% %, calcium fluoride 9%, sodium fluorosilicate 11%. The adhesive is one of nickel oxide, cobalt oxide and manganese oxide. In this embodiment, nickel oxide is used.

[0045] Among the above raw materials, the main component of quartz is silicon dioxide. Its physical and chemical properties are very stable mineral resources. In the present invention, it is the main material for making enamel powder.

[0046] Borax i...

Embodiment 2

[0066] Embodiment two, this is a preferred embodiment of the present invention, and the difference from the above-described embodiment is: the raw material type and weight proportion of electrostatic enamel powder in the present invention are:

[0067] A. Quartz 50.1%;

[0068] B. Borax 12.47%;

[0069] C. Adhesive 5.6%;

[0070] D. The composition of the flux, that is, the weight ratio is: 10.87% of albite feldspar; 5.15% of potassium feldspar, 7.3% of calcium fluoride, and 8.51% of sodium fluorosilicate.

Abstract

The invention relates to the technical field of enamel powder and a preparation method thereof, in particular to electrostatic enamel powder and a preparation method thereof. The electrostatic enamel powder is prepared from the following raw materials in percentage by weight: A, 44 to 55 percent of quartz, B, 8 to 18 percent of borax, C, 4 to 6 percent of adherence promoter, and D, 21 to 38 percent of fluxing agent. The electrostatic enamel powder has the advantages that: 1, processes and energy are saved and drying is avoided; 2, a two-enameling one-sintering process can be realized, namely ground coat and cover coat are sprayed and enameled respectively and sintering is performed at one time; 3, resource utilization rate is high, wherein the utilization rate of the powder is over 98 percent by recycling; 4, waste water and waste gas are avoided; 5, clay or various electrolytes do not need adding into porcelain glaze, the porcelain face is bright, clean and compact after sintering, porosity is low and impurities and different colors are obviously reduced; 6, the spraying quality is high and the porcelain face is uniform and has uniform thickness; and 7, labor is saved and automatic operation and automatic production are realized.

Description

Technical field: [0001] The invention relates to the technical field of enamel powder and its production method, in particular to an electrostatic enamel powder and its production method. Background technique: [0002] Enamel is also called enamel. Traditional enamel products have good acid resistance, alkali resistance, heat resistance, and beautiful surface gloss. They are widely used in industry and daily necessities. When traditional enamel enamel is used, the enamel is first ground into a glaze slurry by the action of clay and a dielectric, or first ground into powder and then mixed with water to prepare a glaze slurry and then coated on the body. [0003] With the development of social science and technology, the electrostatic dry powder spraying process appears. As a new type of spraying process, its principle is: the embryo body is charged positively, and the high-voltage electrostatic generator in the spray gun generates a high-voltage negative voltage, which produ...
