Detailed Description
The following embodiments are described in detail with reference to the accompanying drawings, so that how to implement the technical features of the present invention to solve the technical problems and achieve the technical effects can be fully understood and implemented.
The invention discloses a processing technology of a wood grain decorative wallboard, which comprises the following steps:
providing a cold-rolled steel sheet of predetermined size having a chemical composition content of not more than 0.008% of C, not more than 0.03% of Si, not more than 0.3% of Mn, not more than 0.01% of P, and not more than 0.02% of S;
b, cutting, bending, polishing, cleaning, drying and inspecting to ensure that the surface is smooth;
step c, mixing a hydrophobic and oleophobic agent, wherein the hydrophobic and oleophobic agent comprises 10 mL-100 mL of ethanol, 0.2 g-1.0 g of paraffin, 2 g-15 g of stearic acid and 0.5 g-5 g of calcium carbonate;
d, adhering the wood grain paper by using a hydrophobic and oleophobic agent, and circularly rolling for at least 4 circles by using a press roller, wherein the pressure is 12-16N;
and e, extruding and scraping the residual hydrophobic and oleophobic agent by using a soft scraping blade, drying for 30-60 seconds at 15-20 ℃, tearing off the release film on the surface, and boxing and warehousing.
In the step a, the enameled steel plate is required to adopt a special zero-carbon cold-rolled steel plate, except sufficient iron, the carbon content of the enameled steel plate is not more than 0.008 percent because the content of the steel plate determines enameling property and machining property, the general content of the steel plate is less than 0.19 percent, the carbon content of the steel plate for daily use and sanitary ware is less than 0.1 percent, and the best steel plate is ultra-low carbon steel (zero-carbon steel) with the content of less than 0.01 percent, the general carbon content of the enamel is 0.12-0.19 percent, the lower carbon content of the steel can increase the plasticity and toughness of the steel plate, the cold stamping, welding and other properties of the steel plate can be improved, and the. The carbon content is high and the formability is generally poor. The iron blank is repeatedly processed at the room temperature of about 900 ℃ for many times, and carbon in steel has violent chemical and physical reactions with oxygen, water vapor and water in porcelain glaze in a furnace pit gas: namely, cementite or pearlite decomposes and precipitates free carbon C + O2 → CO2+ CO; c +2H2O → CO2+2H 2. These gases are abundant in the enamel layer, causing the enamel layer to fail in adherence, pinholes to the surface of the enamel layer, some of them to form cells larger than 0.1MM, and some of them to cause fish scaling. Therefore, it is preferable that the carbon content is set to not more than 0.008% in the embodiment of the present invention.
Silicon in an amount not exceeding 0.03% increases the strength of the steel and adjusts the coefficient of expansion, while too high an amount reduces not only the toughness and ductility of the steel but also the adherence of the enamel to the steel. The cold rolled sheet is generally 0.01 to 0.04%, and preferably not more than 0.03% in the present invention.
The presence of a certain amount of manganese in the steel increases the toughness of the steel, gives the steel sheet good punching properties, and it also combines with sulphur into manganese sulphide, which is stable at the enameling temperatures, eliminating part of the harmful SO2 gas.
The sulfur and phosphorus are harmful elements, which increase the brittleness of the steel to deteriorate the processing performance, and simultaneously form SO2 which is unfavorable for a porcelain layer, and the excessive content of the sulfur and the phosphorus easily forms segregation and increases inclusion to reduce the surface quality of the steel, and generally the content is controlled to be less than 0.04%. The present invention preferably does not exceed 0.01% P, and does not exceed 0.02% S.
The final formed cold-rolled steel sheet has yield point of 280MPa or less, tensile strength of 306MPa or more, elongation of 40% or more, good mechanical properties and regular post surface treatment.
After cutting into the shape of specification to fashioned cold-rolled steel sheet through the punch press, through the buffing, guarantee that the surface is smooth, alright add the hydrophobic and oleophobic agent and carry out adhesion wood grain paper, the hydrophobic and oleophobic agent includes ethanol 10mL ~100mL, paraffin 0.2g ~1.0g, stearic acid 2g ~15g, calcium carbonate 0.5g ~5g, can dredge the protective layer of water and grease, can fully glue in adhesion wood grain paper, difficult turn-ups after the rainwater corrodes drops, and is practical effective.
Preferably, the thickness of the wood grain paper is 0.5-1 mm, and the wood grain paper is light and thin and has good wood texture.
And (e) one side of the wood grain paper is soaked with epoxy glue, the viscosity is 20-22 seconds, the permeability is 0-2 seconds, and in the steps d and e, the bonding reliability is good, the bonding is tight, and the practicability is high.
In addition, the outer surface of the wood grain paper is sprayed with printing ink which comprises flashing powder, pearl powder, a binder and a mildew inhibitor, so that the visual attractiveness is enhanced, the wood texture is enhanced, and the curtain wall is more attractive after being decorated.
And finally, scraping redundant hydrophobic and oleophobic agents by a soft scraping blade, drying for 30-60 seconds at 15-20 ℃, drying, tearing off a release film on the surface, and forming the wooden decorative wallboard, so that the attractiveness is greatly enhanced.
It is to be noted that before step c, the surface of the cold-rolled steel sheet may also be treated by a method of pickling with oil or degreasing with alkali or degreasing with acid or degreasing with electrochemical degreasing or by nickel immersion or a combination thereof.
The oil burning and acid washing method comprises oil burning, acid washing, water washing, neutralization and drying; the alkali degreasing method comprises degreasing, washing, alkali leaching and drying; the pickling degreasing method comprises pickling degreasing, washing, neutralizing and drying; the electrochemical degreasing method comprises electrochemical degreasing, water washing, alkaline leaching and drying; the nickel leaching method comprises degreasing, acid pickling, water washing, nickel leaching, neutralizing and drying. Thus, the surface treatment of the blank can be realized. The method has multiple modes, and a cost-adaptive method is selected according to needs, so that the method is convenient and efficient.
