[0004] Tio disclosed in the above patent 2 The preparation of the coating requires high temperature sintering, and the process is relatively cumbersome
Moreover, in the production process of enamelled steel plates in the prior art, due to unbalanced firing, uneven glaze distribution, and thickness of glaze powder, the color difference of the enameled steel plate often results, and the enameled steel plate obtained by the existing firing process still has a porcelain layer. Thick, poor impact resistance and elasticity, short service life and other defects

Embodiment 1
[0030] Such as figure 1 Shown, a kind of production technique of enamelled steel plate of the present embodiment comprises the following steps:
[0031] Step 1. Forming: Cut the steel plate substrate to be processed into the desired shape; the steel plate substrate is first drawn by computer, and then cut into the desired shape by the laser cutting machine according to the digital data of the design drawing input by the computer , and then through the bending machine to make surface features such as face angles, side angles or arcs.
[0032] Step 2. Pretreatment: Chemically treat the formed steel plate substrate to remove pollutants and derust at the same time;
[0033] Step 3, bottom glaze spraying: spray bottom glaze on the steel plate substrate;
[0034] Step 4, drying: drying the base glaze on the steel plate base material sprayed with the primer at 100°C to 250°C to form a biscuit state;
[0035] Step 5. Furnace firing: Preheat the steel plate base material to 400°C, p...

Abstract
The invention provides a production process of an enamel steel plate, comprising the steps of forming, pretreating, ground coat spraying, drying, furnace burning, over glaze spraying, drying, furnace burning and back surface underboarding. The enamel steel plate has the advantages of bright color, even glaze distribution, seismic resistance, noise reduction and long service life, and is safe and environmental-friendly, and can be applied in the industries such as art murals, household enamel products, industries, buildings and the like. The enamel steel plate in the invention is a compound material which is formed by the steps that a high quality steel plate as a substrate is processed by a static dry method and then is burnt with inorganic nonmetallic material at high temperature so that tight chemical bonds are between the high quality steel plate and the inorganic nonmetallic material generate, and the enamel steel plate is a perfect combination of metals and inorganic materials. The enamel steel plate has flexibility of a steel plate substrate and also has the characteristics of acid-base resistance, endurance, non-combustion, safety, environmental protection and the like of an inorganic enamel layer. The enamel steel plate in the invention is static-free and is easy to clean, the enamel surface is fine and smooth, shakeproof, compression resistant and noise resistant and has small possibility of dust accumulation, the service life is long, and the enamel steel plate does not need to be maintained for 50 years under regular atmospheric environment.
Description
technical field [0001] The invention relates to a production process of decorative materials used in art murals, household enamel products, industry and construction industries, in particular to a production process of enamel steel plates. Background technique [0002] The enamel process originated from glass decoration metal. Ancient Egypt appeared first, followed by Greece. In the 8th century, China began to develop enamel, and by the end of the 14th century, the enamel technology became more and more mature. In the middle of the 15th century, the products made during the Jingtai period of the Ming Dynasty were particularly famous, so they were called cloisonne. In the middle of the 19th century, the development of various industries led to the rise of steel plate substrate enamel, creating a new era of modern enamel. [0003] The base material of enamelled steel plate is a complex non-organic coating material that provides protection for the metal. It not only has the s...
