Description
Technical field
The present invention relates to a kind of production technique, especially relate to a kind of production technique of vulcanization member.
Background technology
Along with the development of science and technology, automobile industry achieves tremendous development, and various high performance automobile is more and more universal.In order to ensure the high-performance of automobile, the various automobile devices producing automobile also need to have higher performance.Non-corrosibility, as a kind of important performance indexes of automobile device, is generally all provided with protective process technology at present in the production technique of automobile device.Traditional protective process technology is generally the pure zinc technology of plating, but pure zinc coating obtain antiseptic property more and more can not the meeting the demands of automobile device performance, be plated admiro technique at present and replaced.Zinc-nickel alloy electroplating layer has the performances such as the protection against corrosion more excellent than traditional pure zinc coating, has been widely used in the production technique of various devices of automobile industry.
Vulcanization member is that auto-producing commonly uses device, and generally comprise pipe in aluminium, be positioned at iron outer tube outside aluminium pipe and rubber, in aluminium, pipe, iron outer tube and rubber three are combined by sulfuration process.Because aluminium inner tube material is amphoteric metal, be very easy to be dissolved in acid and alkaline liquid, and be all adopt strong acid or strong base solution in the plating process of iron outer tube, so to manage and rubber carries out vulcanization reaction and finally forms vulcanization member product again with in aluminium need separately electroplated zinc nickel alloy art breading to be carried out to iron outer tube in the production technique of vulcanization member after.
The production technique of existing vulcanization member generally comprises following steps: pipe in aluminium is carried out ultrasonic cleaning and Shot Blasting; Iron outer tube is carried out electroplated zinc nickel alloy process; Iron outer tube after plating is carried out passivation and sealing treatment post-drying; Pipe in aluminium after ultrasonic cleaning and Shot Blasting and the iron outer tube of drying are carried out gluing process respectively: the junction of pipe and iron outer tube and rubber coated with adhesive and drying respectively in aluminium; Pipe and iron outer tube and rubber in aluminium after gluing process are put into mould to carry out vulcanization reaction and finally obtain vulcanization member product.In the production technique of existing vulcanization member, after electroplating work procedure and before gluing treatment process the passivation that exists and sealing treatment operation first generate on zn-ni alloy deposits one deck very thin, in granular and that covering performance is good passivation film, then close rete preferably at the Surface Creation bright property of passivation film and planarization.Passivation film becomes independent to be existed mutually, the normally compound of oxidized metal, it plays a part iron outer tube and corrosive medium to separate completely, prevent iron outer tube from contacting with corrosive medium, thus making iron outer tube substantially stop dissolving formation passive state to reach etch-proof effect, the existence closing rete becomes granular defect to overcome passivation film, keeps surface-brightening and the planarization of iron outer tube, make vulcanization member have good outward appearance on the one hand, be convenient to follow-up vulcanization reaction on the other hand and carry out smoothly.But, the existence closing rete can cause following problem: closed rete has the feature such as bright property and planarization, cannot combine closely between iron outer tube and tackiness agent in follow-up coating technique, iron outer pipe surface is bright smoothly more easily to come unstuck, cause the degumming rate of vulcanization member very high thus, and vulcanization member comes unstuck and will cause that product pressure-off power declines, performance and durable inefficacy, cause automobile generation car load abnormal sound, and motor live time is declined greatly.
