Abstract
The present invention discloses a composition of lead-free aluminium enamel for pure aluminum sheets and aluminium alloy sheet materials, which has the structural formula of SiO2-B2O3-TiO2-R2O. The namel has the characteristics of no lead pollution to environment, good acid-proof chemical stability, good adherence with a base material, etc. The enamel is suitably used for surface decorations with various colors and protection on pure aluminium or aluminium alloy.
Description
Technical field
The invention belongs to enamel enamel technical field, be specifically related to a kind of unleaded aluminium enamel enamel, be mainly used in the surperficial application of slip of metal fine aluminium and aluminium alloy.
Background technology
The melt temperature of metal fine aluminium and aluminium alloy is lower, the existing aluminium enamel enamel that is used for the surperficial application of slip of metal fine aluminium and aluminium alloy, in order to satisfy the requirement of low melting point complete processing, its composition generally all contains a large amount of plumbous oxide compositions, and high-load plumbous oxide can cause bigger pollution to environment in the use of process of producing product and product; In addition, existing leaded aluminium enamel enamel acid resistance is relatively poor relatively, and general acid resistance is no more than the A level.
Summary of the invention
The objective of the invention is to invent does not a kind ofly have the unleaded relatively preferably aluminium enamel enamel of Lead contamination, acid resistance to environment.
A kind of unleaded aluminium enamel enamel provided by the invention mainly comprises in its prescription: alkalimetal oxide R
2O, silicon-dioxide SiO
2, titanium dioxide TiO
2, boron oxide B
2O
3, it is characterized in that: each component is at SiO
2-B
2O
3-TiO
2-R
2Weight percent in the O composition system is:
Silicon-dioxide SiO
2: 28.00-38.00%
Boron oxide B
2O
3: 2.00-10.00%
Titanium dioxide TiO
2: 20.00-30.00%
Alkalimetal oxide R
2O:20.00-40.00%
Alkalimetal oxide R wherein
2O adopts the mixture of sodium oxide, potassium oxide and Lithium Oxide 98min, and the mol ratio between them is 4: 3: 2.
This component system also can add the aluminium oxide Al that accounts for the gross weight 0.5-5.0% of system outward
2O
3, aluminium oxide Al
2O
3Enter the network of silicon-oxy tetrahedron, can improve the density of network body, favourable to improving unleaded aluminium enamel crystalline chemical stability and physical strength.
This component system also can add the weisspiessglanz Sb that accounts for the gross weight 0.5-5.0% of system outward
2O
3, to improve the opacifying power of unleaded aluminium enamel enamel.
In the above proportioning: SiO
2Amount more lower slightly than conventional formulation because SiO
2Measure highly more, its surface tension is high more, and adherence is poor more, and firing temperature is also high simultaneously, lowly can make whole enamel forfeiture physical strength and chemical stability but cross, and determines that therefore its weight ratio is between 28.00-38.00%.
B
2O
3Can significantly reduce surface tension, improve adherence, improve porcelain facing gloss, in this system, can do the enamel base stock again within the specific limits simultaneously, but consider that its coefficient of expansion is less, so the introducing amount be defined as 2.00-10.00%.
TiO as strong opacifying agent
2, its introducing mainly is to strengthen enamel to the aluminium sheet opacifying power, improves the chemical stability of unleaded aluminium enamel enamel, and strengthens the physical strength of enamel layer, because aluminium enamel is to burn till TiO being lower than under 600 ℃
2Do not have the secondary crystallization, so the introducing amount determines at 20.00-30.00%, than traditional enamel opacifying agent content height.
R
2O is the general name of monovalent base metal oxide, adopts sodium oxide Na in the native system
2O, potassium oxide K
2O and Lithium Oxide 98min Li
2The mixture of O, the mol ratio between them is 4: 3: 2.This mainly is a chemical stability of utilizing " mixed alkali effect " significantly to reduce firing temperature and improve system, R
2The introducing amount of O is defined as 20.00-40.00%.
The making and the use of unleaded aluminium enamel enamel are as follows:
Qualified various required industrial chemicals and raw mineral materials by the prescription weighing, behind the thorough mixing, are sent into temperature and are 1100-1150 ℃ kiln and found, treat the furnace high-temperature melt reel off raw silk from cocoons do not have knot after, can come out of the stove quenches is broken into the enamel frit; After the frit drying, with mixed grindings such as itself and suspension agent, wetting ability pigments to the suitable fineness and the glaze slip of unit weight, by spraying glaze slip is applied on the surface-treated already fine aluminium or aluminium alloy equably then, promptly enter temperature after the drying and be in 550 ℃ ± 20 ℃ the kiln and burnt till 4-8 minute, promptly get the disposable aluminium enamel that burns till after the cooling of coming out of the stove.
Therefore lead-free element in the component of unleaded aluminium enamel enamel provided by the invention does not produce plumbous volatilization and separates out pollution on the environment in the use of process of producing product and product; With prior art relatively, utilization of the present invention " mixed alkali effect " significantly reduces firing temperature and has improved the chemical stability of system, makes the acid resistance of enamel significantly improve, and has selected silicon-dioxide SiO simultaneously rightly
2The introducing amount, not only guaranteed the acid resistance of enamel but also made enamel and the adhesion property of base material is improved.The present invention is applicable to surface decoration and the protection of doing various colors on fine aluminium or aluminium alloy.
