Manufacturing method for enamel decorative plate imitating wood grains

Abstract

The invention discloses a manufacturing method for an enamel decorative plate imitating wood grains, comprising the steps of: (1) decomposing wood grains; (2) moulding sheet steel; (3) sintering a ground coat; (4) preparing an enamel frit as a standby; (5) preparing an enamel primary plate; (6) preparing a silkscreen enamel base frit for standby application; (7) imprinting one or several silkscreen printing inks and one or several silkscreen color patterns decomposed from step (1) on transfer paper and sealing a film; (8) pasting the transfer paper on the enamel primary plate for sintering, thus obtaining the enamel decorative plate imitating wood grains after cooling. The enamel decorative plate imitating wood grains of the invention not only has the advantages of enamel decorative plates with wood grains, such as lasting and corrosion resisting, but also has the simple and elegant artistic effects as decorated by wood materials. Color painting and material grain-like pigments are both inorganic glass materials, and the pattern pigment and the enamel layer are closely integrated after high-temperature fusion. Thus, the enamel decorative plate of the invention has durable corrosion resistance and weather ability, amazing abrasive resistance and impact resistance, excellent fireproof performance, elegant appearance, as well as environmental friendly and economical properties.

Description

technical field [0001] The invention relates to a method for manufacturing an enamel decorative board, in particular, the invention relates to a method for manufacturing an enamel decorative board imitating wood grain. Background technique [0002] Enamel is a metal coated with one or more layers of inorganic vitreous materials on its surface. After high temperature, the surface coating is melted, so that complex physical and chemical changes occur, and the metal and its surface coating are firmly combined to form a kind of enamel. Composite material, which has both the mechanical strength and easy processing characteristics of metal materials and the corrosion resistance, wear resistance, heat resistance, non-toxicity and rich decorative effects of inorganic glass materials. The application of enamel is very wide, ranging from daily necessities such as washbasins, cups to bathtubs, cabinets, chemical reaction tanks, oil pipelines, etc. used in industrial production, and soc...

Problems solved by technology

[0003]At present, the color varieties of decorative enamel steel plates in my country are relatively monotonous, mostly plain colors, and occasionally there are some enamel decorative plates with murals and calligraphy fonts, but in general still not rich enough

At present, there are technologies on the market that use screen printing technology or brushing technology to make patterns on the surface of the enamel board, but it is limited to the front of the enamel board, and the patterns produced are also limited to figures, landscapes, etc. How to make patterns on the side of the enamel board? There is no way to do it, because the coloring materials used for enamel must be high temperature resistant and inorganic, there are not many coloring materials with this characteristic in nature and the coloring is limited, so they cannot have CMYK like paper printing technology Four basic colors (cyan, magenta, yellow, and black) can be mixed to produce rich colors in nature, so the colors and patterns used for enamel printing also have many limitations, and it is not possible to print various patterns you want At the same time, there is also the technology of imitating wood grain by mixing and spraying glazes of various textures on the metal substrate and firing them, but the operation is complicated and the imitated wood grain enamel is not realistic.
