Detailed description of the invention
Now with regard to the spring anti-corrosion material of the present invention and the technical scheme of spring method for anticorrosion treatment and the beneficial effect that can be generated by thereof, in conjunction with accompanying drawing and form, describe in detail as follows:
As it is shown in figure 1, the present invention provides a kind of spring method for anticorrosion treatment, comprise the steps:
S1: pretreatment of base material: base material is carried out surface coarsening process, then that substrate surface treatment is clean；
S2: spray painting: the base material through pre-treatment is carried out spray painting；
S3: paint solidification: the base material through spray treatment is transferred in curing oven, is to slowly warm up to solidification temperature 80-300 DEG C, keep 5-60min at this temperature；
S4: be down to room temperature by solidifying complete base material, obtain the spring possessing antiseptic property；
Wherein, in described step S2, the coating used is polyurethane powder.
Wherein, in described step S1, carry out surface coarsening process by sandblasting or ball blast, by compressed air, substrate surface is blown off.
Wherein, in described step S2, the mode of described spray painting is compressed air spraying or electrostatic spraying.
Wherein, in described step S3, described solidification temperature, between 180-200 DEG C, keeps 10-30min at this temperature.
The present invention additionally provides a kind of spring anti-corrosion material for above-mentioned spring method for anticorrosion treatment, described anti-corrosion material is selected from polyurethane powder.
For further illustrating the beneficial effect that the present invention can be generated by, incorporated by reference to refering to table 1.
Wherein, the immersion postadhesion power test result of the spring that the spring method for anticorrosion treatment of water-soluble acrylic Amino-Polyester baking vanish, polyesters and triglycidyl isocyanurate mixture and monocomponent polyurethane spring method for anticorrosion treatment and the present invention that table 1 is respectively adopted comparative example obtains after processing, in comparative approach, it is respectively adopted water soluble acrylic acid Amino-Polyester baking vanish, polyesters and the mixture of triglycidyl isocyanurate and monocomponent polyurethane sprays as coating, in the present invention, polyurethane powder is used to carry out spray painting as coating.The method of immersion postadhesion power test is that the spring workpiece entirety after processing immerses in distilled water, takes out after soaking 24 hours and 48 hours respectively, and concrete method of testing sees GB GB/T1733-1993.Cross-hatching (GBT 9286-1998) is used to judge experimental result.
Table 1: the present invention and the spring immersion postadhesion power test result obtained by comparative approach
| Sequence number | Sprayed on material | 24h classification results | 48h classification results |
| 1 | Water-soluble acrylic Amino-Polyester baking vanish | 5 grades | 5 grades |
| 2 | Polyesters and triglycidyl isocyanurate mixture | 5 grades | 5 grades |
| 3 | Monocomponent polyurethane | 5 grades | 5 grades |
| 4 | Polyurethane powder | 3 grades | 4 grades |
As can be seen from Table 1, use the spring that the spring method for anticorrosion treatment of the present invention obtains, compare employing water-soluble acrylic Amino-Polyester baking vanish, the spring that polyesters and triglycidyl isocyanurate mixture and monocomponent polyurethane spring method for anticorrosion treatment obtain, its immersion postadhesion power performance has exceeded one to two ranks, simultaneously, the preservative challenge test result of spring also indicates that, the spring that the spring method for anticorrosion treatment using the present invention to provide obtains, after immersion, spring anticorrosive coat surface is also without substantially peeling off, and use the spring that the spring method for anticorrosion treatment of comparative example obtains, after distilled water immersion, there is significantly peeling on anticorrosive coat surface.
The salt spray resistance method of testing of spring uses GB GBT-10125-2012 neutral salt spray test, experimental period is 120 hours, the method of inspection uses GB GB/T 6461-2002, the salt spray resistance experiment point two groups of spring is carried out, the salt spray resistance test of first group is carried out under spring is not assembled, the salt spray resistance test of second group is all repeatedly to assemble four times, and sample is carried out in the case of there is certain abrasion.Result shows, the spring not being assembled is in salt spray resistance is tested, and its salt spray resistance is nine grades, repeatedly assembles four times, and the spring in the case of the certain abrasion of sample existence is in salt spray resistance is tested, and its salt spray resistance also can reach Pyatyi.
Also can learn in combination with experimentation obtains spring sample, use the spring that the spring method for anticorrosion treatment of the present invention obtains, there is the salt spray resistance of excellence, spring method for anticorrosion treatment of the prior art, many employing anti-corrosion of metal processing modes, obtain only have anti-corrosion of metal process and without the spring of polymeric coating layer, the spring so obtained, after repeatedly assembling four times, spring salt spray resistance is only at two to three grades, the technique simultaneously used can be to environment, and use the spring method for anticorrosion treatment of the application, not only technique environmental protection, and the spring obtained, after repeatedly assembling four times, the salt spray resistance of spring is up to Pyatyi, in the case of not assembling, its salt spray resistance even can reach nine grades, this is that prior art cannot realize.
Meanwhile, using anti-corrosion of metal processing mode in prior art, cost is high, and the spring method for anticorrosion treatment that the application provides, while ensureing the corrosion resistance that spring is good, moreover it is possible to cost-effective.
To sum up, the spring anti-corrosion material of present invention offer and spring method for anticorrosion treatment, not only low cost, environmental protection, and spring after treatment can be made to have superior decay resistance, adhesive force, wearability and processing characteristics.
Although the present invention has utilized above-mentioned preferred embodiment to illustrate; so it is not limited to protection scope of the present invention; any those skilled in the art are within without departing from the spirit and scope of the present invention; above-described embodiment carries out various variation and amendment still belongs to the scope that the present invention is protected relatively, and therefore protection scope of the present invention is with being as the criterion that claims are defined.
