Description
Technical field
The invention belongs to mechanized equipment technical field of coatings, especially relate to a kind of mechanized equipment low prepared surface high-performance anti-corrosive primer and preparation method.
Background technology
The surface treatment method that mechanized equipment is conventional has: hand cleaning, derusting by sandblasting, impeller blasting, chemical derusting, wherein in the majority with derusting by sandblasting and impeller blasting, both derusting methods are that efficiency is high relative to maximum advantage other two kinds of rust cleaning modes, price is low, effective, it is more suitable for processing large-scale component, and mechanized equipment ratio for self-manufactured content domestic at present is high, various in style, complex-shaped, structure is strange, dead angle is many, size differences is big, derusting by sandblasting and impeller blasting are required higher, not fully reach the rust cleaning standard that sandblasts, easily occur that rust cleaning is not thorough, the rust cleaning weak effect such as ball blast insufficient strength, the phenomenons such as rust cleaning efficiency is low, it is extremely difficult to Sa2.5~Sa3.0 or the St3 level of surface treatment requirement, and then have impact on the adhesive force of mechanized equipment priming paint and the anti-corrosive properties of Bulk coat.Along with the fast development of mechanized equipment manufacturing technology, mechanized equipment process for treating surface and mechanized equipment priming paint technology of preparing are proposed higher requirement.
Conventional mechanized equipment priming paint has epoxy ester undercoat, epoxy zinc rich primer, epoxy iron red shop primer, alcohol acid primer, acrylic primer and polyurethane primer.The shortcomings such as wherein epoxy ester undercoat, epoxy iron red shop primer, alcohol acid primer, acrylic primer and polyurethane primer ubiquity coating efficiency are low, cold drying poor performance, salt spray resistance are poor, and although but epoxy zinc rich primer antiseptic property excellence exists that coating is relatively costly, internal stress is bigger after film curing, easily ftracture, come off, be unfavorable for large scale application.It addition, the surface treatment of these priming paint requires higher (being Sa2.5~Sa3.0 or St3 level), if sandblasting or ball blast effect are bad, these priming paint easily come off from base material due to poor adhesive force.Therefore, the mechanized equipment coating specification of fast development is met in the urgent need to a kind of low prepared surface high-performance anti-corrosive primer.
Summary of the invention
For overcoming the weak point in above-mentioned technology, disclosure one mechanized equipment low prepared surface high-performance anti-corrosive primer, this coating has the adhesive force of excellence, good film-forming on the moist base material of rusty scale less than 80 μm, meets the requirement of mechanized equipment low prepared surface;Paint film also has water-fast, salt spray resistance, oil resistant and the chemical proofing of excellence, and rustless property highlights, and meets the permanent anticorrosion of mechanized equipment and requirement of shelter;It addition, this coating also has the advantages such as rate of drying is fast, low-temperature setting performance is good, meet the mechanized equipment requirement to coating efficiency.Therefore, this coating can solve that substrate surface treatment is required high (easily sandblasting or ball blast are bad cause coating easily to come off) by current China mechanized equipment priming paint, coating efficiency is low, painting cost is high and the problem demanding prompt solution such as poor corrosion resistance.
