Description
Technical field
The present invention relates to motor processing and manufacturing technical field, be specially the method for anticorrosion treatment of motor water cooling base inner chamber.
Background technology
The support water-cooled machine is the existing conventional product.Because the long-term work of water cooling base inner chamber in the mobile hot water more than 50 ℃, is subjected to the souring of circulating water, coating must have excellent water tolerance and anti-scouring force, and therefore the preservative treatment to the water cooling base inner chamber has proposed specific (special) requirements.At present, the anticorrosive paint that adopts usually is an epoxy zinc rich primer.Existing motor water cooling base adopts assembling and annealing in process earlier, carries out the preservative treatment of water cooling base inner chamber again.Because elongated narrow and small, the complex structure of water cooling base intracavity space after the assembling is difficult to effectively carry out Coating Pretreatment operation, can't guarantee good coating quality, and can only adopts and irritate the method that is coated with and carry out external coating and realize preservative treatment.Water cooling base inner chamber antiseptic effect through above-mentioned existing method for anticorrosion treatment processing is undesirable, service life is shorter, can't reach designing requirement.
Summary of the invention
The present invention is undesirable for the method for anticorrosion treatment antiseptic effect that solves existing motor water cooling base inner chamber, water cooling base short problem service life, and a kind of method for anticorrosion treatment of motor water cooling base inner chamber is provided.This processing method can greatly improve antiseptic effect, can make reach 20 years the service life of water cooling base.
The present invention adopts following technical scheme to realize: the method for anticorrosion treatment of motor water cooling base inner chamber, and the inner chamber to each component parts of water cooling base sprays paint earlier, and then assembles, anneals; Lacquer spraying technique is as follows: one, surface of internal cavity is handled, 1, surface of internal cavity is carried out ball blast or blasting treatment (ball blast, sandblast are existing known, ripe process of surface treatment), make the surface of internal cavity derusting grade reach the Sa2.5 level of GB8923 standard, roughness reaches 40～70 μ m; Adopt craft and powertool cleaning at each parts surface of internal cavity ball blast or place, blasting treatment blind area, derusting grade reaches the St3 level of GB8923 standard; 2, surface of internal cavity is cleaned (thoroughly removing pollutants such as surface of internal cavity oil, fat, dust); Two, application, 1, surface of internal cavity is sprayed, high mode waterborne zinc-rich thermostable rustproof lacquer, film thickness 50～80 μ m are adopted in spraying; 2, after the spraying workpiece was placed 30～60 minutes, made the paint film surface drying; Three, maintenance behind the paint film surface drying, is lower than in relative humidity under 65% the environment, every 30～40 minutes coating surface is sprayed a water smoke, carry out 4～5 times (at ambient humidity greater than 65% o'clock, under overcast and rainy season, need not to carry out water smoke handles), place then and make the full cross-linked curing of paint film.The present invention is owing to be to spray paint earlier afterwards to assemble, anneal, therefore can handle surface of internal cavity fully, and provided concrete process of surface treatment parameter, also be convenient to simultaneously the detection of coating quality after the application, film thickness, guaranteed that water cooling base inner chamber coating quality is even, consistent, satisfied the long-effective corrosion quality requirement of water cooling base inner chamber.If roughness is too big, be prone to thick coating crest place, trough place coating and approach, be full of cracks appears in trough place coating, and crest place coating antiseptic effect does not reach requirement; If roughness is too little, the mechanical bond power of coating and metallic matrix is little, and adhesive force is equally also relatively poor.The adhesion of coating and metal surface is poor; the problem that can occur disbonding on the one hand; even coating is not peeled off temporarily on the other hand; but also can not firmly can not form a firm entity because of combining between coating and metallic matrix; cause coating to produce good electrochemical protection effect to matrix; in corrosive environment, can cause coating to be peeled off in early days, reduce the anticorrosion useful life of product.Adopting sprays paint earlier afterwards assemble, anneals, and carries out under 550～600 ℃ of high temperature and anneal, therefore, height is anti-corrosion except that having for the anticorrosive paint that need select for use, high adhesion force, Gao Naihou, anti-wash away and good self-healing, also to have high temperature tolerance.Conventional adopt anticorrosive paint---epoxy zinc rich primer is bonding agent with epoxy resin, therefore about 200 ℃ of the high-temperature resistants of paint film are not suitable for the present invention.The present invention is preferred high mode waterborne zinc-rich thermostable rustproof lacquer in numerous anticorrosive paints, this antirust paint has high anti-corrosion, high-temperature resistant (650 ℃), high adhesion force, Gao Naihou and good self-healing, the long-effective corrosion that adapts to workpiece in the water has satisfied the technological requirement of the high annealing that eliminates stress after the workpiece welding.High mode waterborne zinc-rich thermostable rustproof lacquer is the existing known products that sell in market, and concrete model is AL-551, by Wuhan Fumaishi New Material Chemical Co. Ltd.'s production and selling.During this product export, be divided into solid material and liquid material, the weight allotment ratio that is provided according to product description by the user during use is carried out solid-liquid and is mixed.The weight allotment ratio that product description provides is solid material: liquid material=72: 28.Carry out the solid-liquid mixing in this weight allotment ratio and can satisfy needs of the present invention.The present invention has also carried out the film forming maintenance, and has provided concrete maintaining process parameter and film thickness requirement.
Processing method science of the present invention, reasonable can be guaranteed the coating quality of forming film, can make the antiseptic effect of water cooling base and reach 20 years useful life.
It is that main film forming substance and high mode potassium silicate carry out compound that high mode waterborne zinc-rich thermostable rustproof lacquer adopts the high mode lithium metasilicate, adding fluorine activating agent and high-purity zinc powder is made, have high anti-corrosion, high-temperature resistant, high adhesion force, high performance such as weather-proof, the key technical indexes sees Table 1.
