Embodiment

[0022] Take epoxy resin E-51 by weight ratio: 16.4%, epoxy resin E-31: 5.8%, polyurethane 12.3%, 3,5-diamino-p-chlorobenzoic acid isobutyl as curing agent: 7.5%; diamond Micro powder (W7) 4%, electrolytic copper powder 40%, cerium oxide powder 14%.

[0023] The solid-phase diamond powder (W7), electrolytic copper powder, and cerium oxide powder are ball-milled for 1 hour with a ball mill, passed through a 180-mesh sieve, and set aside; the liquid-phase epoxy resin, polyurethane, and curing agent are mechanically stirred for 0.5 hours according to the ratio, and then Add the solid-phase powder mixture and stir for 0.5 hours; inject the castable into the mold coated with silicone grease release agent, shake and exhaust, and then solidify. The curing process is 4 hours at 60°C, 4 hours at 80°C, and 4 hours at 100°C.

Embodiment 2

[0025] Take epoxy resin E-44 by weight: 21.2%, epoxy resin E-31: 7.3%, polyurethane 6.5%, 3,5-diamino p-chlorobenzoic acid isobutyl ester curing agent as curing agent: 8% , diamond powder (W7) 5%, electrolytic copper powder 45%, cerium oxide powder 7%.

[0026] The preparation method of this embodiment is the same as that of Example 1.

Embodiment 3

[0028] Take epoxy resin E-51: 19% by weight, epoxy resin E-31: 8.7%, polyurethane 5.6%, 3,5-diamino-p-chlorobenzoic acid isobutyl as curing agent: 8.7%, diamond Micro powder (W7) 6%, electrolytic copper powder 40%, cerium oxide powder 12%.

[0029] The preparation method of this embodiment is the same as that of Example 1.

[0030] In actual production, the raw material composition ratio of the diamond resin honing oil stone of the present invention can be adjusted according to the difference in material and hardness of the engine cylinder liner, and the diamond resin honing oil stone of corresponding hardness can be prepared. The above-mentioned honing oil stone is processed on a Z4-600-125 Gehring honing machine to process the cylinder liner, and the texture quality is tested with a German Hormel T8000 roughness meter. It takes 30-40 seconds for the honing oilstone to complete a honing process, and the pass rate of the processed cylinder liner pattern is over 96%. After pr...

Abstract

The invention relates to a diamond resin honing stone for ultra-precisely machining a cylinder sleeve platform anilox roller and a preparation method thereof. The diamond resin honing stone comprises the following raw materials in percentages by weight: 20-30% of epoxy resin, 5-15% of polyurethane, 2-6% of W7 diamond micron powder, 35-45% of electrolytic copper powder, 5-15% of cerium oxide powder and 4-12% of isobutyl 3,5-diamino-p-chlorobenzoate as a solidifying agent. The preparation method comprises the following steps of: mixing the raw materials according to percentages by weight, pouring and forming to prepare the diamond resin honing stone for ultra-precisely machining the engine cylinder sleeve platform anilox roller. The engine cylinder sleeve platform anilox roller which is precisely honed by utilizing the diamond resin honing stone prepared by the preparation method disclosed by the invention has uniform deep grooves, the uniform width and distance and high platform precision, and an engine cylinder sleeve reaches EU III and IV emission standards.

Description

technical field [0001] The invention relates to an ultra-precision machining cylinder liner platform reticulated diamond resin honing oil stone and a preparation method thereof. Background technique [0002] The cylinder liner is a key part of the internal combustion engine. The inner surface of the cylinder liner together with the top of the piston, the piston ring and the bottom surface of the cylinder head constitute the combustion chamber of the engine. The quality of its processing directly affects the assembly performance and service performance of the engine. [0003] In the use of the engine, the platform mesh cylinder liner has the following advantages: (1) shorten the running-in time of the cylinder liner and prolong the life of the cylinder liner; (2) increase the bearing area and improve the sealing performance; (3) enhance the oil storage lubrication function and improve Effective power; (4) Reduce engine oil combustion, which is conducive to meeting emission st...
