Abstract
The invention discloses a kind of production technology of specular aluminium, its feature comprises following production stage: (1) is rolled and prolonged, and (2) polish, and (3) deoil, (4) degreasing, (5) toast, (6) coating is modulated, and (7) coat, (8) secondary baking, (9) detect, (10) pad pasting, (11) packed products; The modulation of described step (6) coating is formulated by the part by weight of following raw material: unsaturated polyester varnish 75 ~ 85 parts, pigment 8 ~ 13 parts, metal carboxylate 2.5 ~ 3.5 parts, high performance chlorine modified resin 1.5 ~ 5 parts, acrylic resin 1.2 ~ 4.8 parts, broken bubble polysiloxanes 1.1 ~ 6 parts, polyvinyl butyral resin 0.8 ~ 4.2 part.The present invention improves the transparency of specular aluminium, strengthens weather resistance, solvent resistance and levelability, change condition of cure and improve production technology, and color variety is various.
Description
Technical field
Patent of the present invention relates to the production technology of surface of aluminum plate process, dragon its relate to the production technology of minute surface aluminium sheet.
Background technology
Present specular aluminium mainly passes through jointed anode oxidation processes, as patent (publication number CN10532142A), anodized aluminium sheet is placed in corresponding electrolyte (as sulfuric acid, chromic acid, oxalic acid etc.) as anode, under specified conditions and impressed current effect, carry out electrolysis.The aluminium plate oxidation of anode, forms alumina flake on the surface, and its thickness is 5 ~ 20 microns.Anodized complex process, cost is high, color is dull, and needs through repeatedly washing time between life, has serious impact with the health of highly acid water on environment and direct labor.
Summary of the invention
In order to solve the problem, the production technology that the invention provides a kind of specular aluminium not only improves the transparency of specular aluminium, strengthens weather resistance, solvent resistance and levelability, changes condition of cure and improves production technology, and color variety is various, cost is low, environmental protection.
A kind of production technology of specular aluminium, comprise following production stage: (1) is rolled and prolonged, (2) polish, and (3) deoil, (4) degreasing, (5) toast, (6) coating is modulated, and (7) coat, (8) secondary baking, (9) detect, (10) pad pasting, (11) packed products;
The modulation of described step (6) coating is formulated by the part by weight of following raw material:
Unsaturated polyester varnish 75 ~ 85 parts, pigment 8 ~ 13 parts, metal carboxylate 2.5 ~ 3.5 parts, high performance chlorine modified resin 1.5 ~ 5 parts, acrylic resin 1.2 ~ 4.8 parts, broken bubble polysiloxanes 1.1 ~ 6 parts, polyvinyl butyral resin 0.8 ~ 4.2 part.
Described step (5) baking is characterized in that the temperature of toasting is 140 ~ 160 DEG C, and the time is 28 ~ 40 seconds; The temperature of described step (8) secondary baking 220 ~ 260 DEG C, the time is 80 ~ 100 seconds.
The production technology of this bright a kind of specular aluminium has following beneficial effect:
First: do not need through overpickling and anodized, more environmental protection, second: modulated by step (6) coating, improve the transparency of specular aluminium, strengthen weather resistance, solvent resistance and levelability, change condition of cure and improve production technology, and color variety is various.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is specifically described.
A kind of production technology of specular aluminium, comprise following production stage: (1) is rolled and prolonged, (2) polish, and (3) deoil, (4) degreasing, (5) toast, (6) coating is modulated, and (7) coat, (8) secondary baking, (9) detect, (10) pad pasting, (11) packed products;
The modulation of described step (6) coating is formulated by the part by weight of following raw material:
Unsaturated polyester varnish 80 parts, pigment 10 parts, metal carboxylate 3 parts, high performance chlorine modified resin 2 parts, acrylic resin 1.5 parts, broken bubble polysiloxanes 2.5 parts, polyvinyl butyral resin 1 part.
Described step (5) baking is characterized in that the temperature of toasting is 150 DEG C, and the time is 30 seconds; The temperature of described step (8) secondary baking 230 DEG C, the time is 90 seconds.
Last it is noted that obviously, above-described embodiment is only for example of the present invention is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of amplifying out or variation be still among protection scope of the present invention.
