Abstract
The invention relates to a repairing method for an easy-to-wear component. According to the repairing method, a bonding agent, a hardener and filler are mixed according to a mass ratio of 0.55:0.45:1.2 to obtain a mixed paster I; the bonding agent, the hardener and the filler are mixed according to the mass ratio of 0.55:0.45:1.05 to obtain a mixed paster II; and then the mixed paster I is used to carry out a filling process on a roughed worn surface, after the a worn component is dried, the mixed paster II is used for repairing, and finally a worn surface is subjected to a refining process to complete repairing. After the worn component is repaired via the method, a surface of the worn component is smooth and fine, the method is simple, raw materials are cheap, the amount of scrapping a main body component or a spare part is greatly reduced, the production cost is lowered, and the use time of equipment is prolonged.

Background technology
in the conventional abrasive material production process, many equipment directly contact with the abrasive material powder, industrial production causes contact portion easily to be subject to the wearing and tearing of abrasive material powder for a long time, grinding, cause the part link, wearing and tearing appear in key position, because equipment is strict to interior space dimension, appearance along with wearing and tearing, the aperture, it is large that cavity size becomes, cause the equipment operation exception, brought a lot of uncertain factors for abrasive material powder production process, cause the production timeliness to reduce, the processing precision reduces, affect product quality, if main element or the parts of wearing and tearing are directly changed, increased production, processing cost, increased the enterprise operation cost.
Summary of the invention
The method for repairing and mending that the purpose of this invention is to provide a kind of easy-abrasion part can reduce the quantity of scrapping main element or parts, reduces production costs, and extension device service time.
The technical solution adopted in the present invention is: a kind of method for repairing and mending of easy-abrasion part comprises the following steps:
Step 1, the alligatoring that the wearing and tearing aspect of easy-abrasion part is mixed the paste I fill to be processed, can take potassium hydroxide to do that coarsening solution is processed, the direct method of roughening such as polishing according to different materials, until till wear surface can fill mixing paste I fully;
Step 2, repair dry: it is drying 2 hours in the environment of 60～70 ℃ that the easy-abrasion part that step 1 was processed is positioned over temperature, then will mix the position that the paste II evenly is coated on roughening treatment in step 1, until smooth surface, be positioned over afterwards temperature and be in the environment of 55～65 ℃ oven dry 1.5 hours;
Step 3, repair the interface micronization processes: the easy-abrasion part after step 2 is processed carries out sanding and polishing to be processed, and completes;
Described mixing paste I is comprised of adhesive, curing agent and inserts, and adhesive, curing agent and inserts mix according to mass ratio 0.55:0.45:1.2;
Described mixing paste II is comprised of adhesive, curing agent and inserts, and adhesive, curing agent and inserts mix according to mass ratio 0.55:0.45:1.05;
Described adhesive is one or both in acrylic acid modified epoxy, polyacrylate, epoxy resin or polyurethane;
Described curing agent is ethylenediamine;
Described inserts is silicon-carbide particle.
2, the method for repairing and mending of a kind of easy-abrasion part as claimed in claim 1 is characterized in that: described inserts is that D50 is one or both in the silicon-carbide particle of 10.5～12.5 μ m, 8.7～10.3 μ m, 7.4～8.6 μ m, 6.1～7.3 μ m.
The invention has the beneficial effects as follows: the present invention mixes the paste I by use the alligatoring wear surface is filled processing, then the wearing terrain drying is repaired with mixing the paste II afterwards, to the method for wear interface micronization processes, completes repairing at last.After adopting the present invention to repair, not only smooth surface is fine and smooth, and method is simple, raw material are cheap cheap, has greatly reduced the quantity of scrapping main element or parts, has reduced production cost, has extended equipment service time.
