Abstract
The invention discloses a photocureable coating for stainless steel, which overcomes the defects of low hardness, low production efficiency and high comprehensive use cost of the traditional general coating by adding 1 to 5% of special adhesion accelerating agent and a little of special inorganic assistant to the traditional photocureable coating. The invention can ensure that the stainless steel materials after the processing procedures of sand blasting, polishing, wire drawing. PVD (Physical Vapor Deposition) magnetron sputtering and the like have good adaptability; the coating can be directly coated on the surface of the stainless steel materials and has the advantages of very strong binding power, working procedure simplification and cost reduction; and the coating efficiency is greatly enhanced.
Description
Technical field
The invention belongs to paint field, is a kind of stainless steel photo-cured coating.
Background technology
The coating material solidified adhesion property that can't obtain of ordinary light and other comprehensive corrosion resistance natures on the existing stainless steel surface, the present invention can solve above problem.1., sandblast pretreatment process commonly used when stainless material is applied to electronic product casing is as follows:; 2., polishing; 3., wire drawing; 4., the PVD magnetron sputtering, this product has excellent adaptability.Stainless steel baking-type coating at present commonly used mainly contains that hardness is not high, and production efficiency is low, the comprehensive high problem of use cost.
Summary of the invention
The objective of the invention is deficiency, provide a kind of at existing stainless steel paint, can directly apply, efficiently, ultraviolet-curing paint that over-all properties is superior.
Technical scheme of the present invention is: add special attachments power promotor and modified inorganic additive in existing photo-cured coating, its concrete proportioning is as follows:
Two functional polyurethane acrylate 10～30%
High functional polyurethane acrylate 10～40%
Gao Guanneng reunion acrylate monomer 5～10%
Simple function group polyacrylic ester monomer 0～15%
Special attachments power promotor 1～5%
Special inorganic additives 0.1～1%
Light trigger 3～5%
Solvent 20～50%
The technique effect of the stainless steel photo-cured coating of the present invention of employing said ratio is as follows:
1., hundred lattice sticking power 5B;
2., with more than wear-resisting 500 circles of the original-pack wear-resisting machine testing RCA of U.S. MOM CM;
3., 5% salt-fog test, under 35 ℃ of situations, 48 hours no changes;
4., constant temperature and humid test: under 75 ℃, 95% humidity condition, 72 hours no changes;
5., thermal shock performance: under-40 ℃ → 25 ℃ → 80 ℃ conditions, rise, drop to a circulation, each temperature spot kept 0.5 hour, (accumulative total 30 hours) no change after 10 circulations;
6., can mix colours 3% in the coating, i.e. look smart ratio 3～5%.
Example formulations:
Two functional polyurethane acrylate 20%
High functional polyurethane acrylate 25%
Gao Guanneng reunion acrylate monomer 8%
Simple function group polyacrylic ester monomer 10%
Special attachments power promotor 3%
Special inorganic additives 1%
Light trigger 3%
Solvent 30%
Claims (2)
1. stainless steel photo-cured coating, proportioning is as follows:
Two functional polyurethane acrylate 10～30%
High functional polyurethane acrylate 10～40%
