Abstract
The invention discloses a kind of preparation method of sharp epoxy resin binder diamond grinding tool, its working lining is made primarily of diamond abrasive, epoxy adhesive, curing agent, auxiliary abrasive, filler and auxiliary addition agent; First by self-sharpening diamond 5 ~ 20 parts, auxiliary abrasive 5 ~ 28 parts, filler 10 ~ 40 parts, other auxiliary addition agents 0.5 ~ 10 part, after mechanical mixture is even, with liquid epoxies 17 ~ 45 parts, after 5 ~ 25 parts, curing agent is mixed together and stirs, by the mode of cast, will have in the said mixture injected plastic mould of mobility, after solidification, obtain sharp epoxy resin binder diamond grinding tool; Above number is mass percent.The present invention compared with the grinding tool of hot-forming preparation, preparation process simple process, energy-saving and emission-reduction, the pollution of solid dust to environment can be reduced, environmental protection, speed of production, compared with external existing product, then there is the advantages such as sharpness is high, self-sharpening is strong, polishing effect is good, the life-span is long.
Description
Technical field
The present invention relates to a kind of grinding tool, espespecially a kind of preparation method of sharp epoxy resin binder diamond grinding tool.
Background technology
Superhard material resin abrasive tools is for abrasive material with superhard material diamond or cubic boron nitride, take resin-oatmeal as bonding agent, add suitable packing material, that is made by preparation, mixing, hot-forming, solidification and the technical process such as machining is had certain geometrical shape, can be suitable for a kind of machining tool that different grinding requires.In superhard material grinding tool, resinoid bonded grinding tool proportion is about 30% ~ 60%, and superhard material resin abrasive tools has raw material and is easy to get, and cost is low; Low-temperature setting, with short production cycle, equipment needed thereby and manufacturing process flow simple; Grinding efficiency is high; Grinding tool self-sharpening is good, not easily blocks, and processed subject surface is not easily burnt; The advantages such as grinding tool has certain elasticity, and polishing performance is good.Affect the factor of the sharpness of superhard material resin abrasive tools, life-span and grinding performance, mainly comprise the factor such as kind and ratio of diamond, resinoid bond.The resin that can be used as polishing abrasive tool at present has many kinds, such as phenolic resins, epoxy resin, polyurethane resin, Pioloform, polyvinyl acetal etc.What wherein grinding tool industry was the most frequently used is phenolic resins, and it has higher heat resistance, has now been widely used for manufacturing resin wheel, resin cutting slice etc.But cause phenolic resins decomposition or softening owing to releasing a large amount of thermal conductances in grinding process, cohesive force declines, abrasive material comes off in a large number, make in actual grinding application, expensive superhard material does not have complete blunt just to come off, this has had a strong impact on grinding efficiency and the grinding ratio of grinding tool, also result in very large waste simultaneously.And have accessory substance in Analysis on Curing Process of Phenolic to generate, adhesion strength is low, and rigidity is comparatively large, and polishing performance is poor, be used for making polishing abrasive tool also not bery desirable.In addition, have the generation of small-molecular-weight accessory substance in solidification process, to ask the grinding tool making densification just must pressurize in the curing process, this will inevitably make complex process.Other various resins, as polyurethane resin, Pioloform, polyvinyl acetal, polyimides, polyphenylene sulfide etc. also all there is complex manufacturing, the factor such as production efficiency is low, poisonous and affect its scope of application.
Epoxy resin (EP) is the very important thermosetting resin of a class, and it is one of most widely used matrix resin in polymer matrix composite.The epoxy resin added after curing agent solidification has good physical and chemical performance, the surface of it and material has excellent adhesive property, dielectric properties are good and cure shrinkage is little, product size good stability, hardness is high, pliability is better, to alkali and most of solvent-stable, is commonly used for the purposes such as cast, dipping, lamination material, bonding agent, coating.Epoxy resin has the strongest cohesive force, has very high cohesive force to metal, the multiple material such as nonmetal.This is convenient to add various inserts in grinding tool very much, and it has higher intensity when inserts large percentage to make grinding tool.Secondly, epoxy resin also has certain heat resistance.Epoxy resin has the heat resistance of 20 ~ 300 DEG C after by anhydride-cured.If inorganic filler content is high, heat resistance also can improve further.3rd, epoxy resin has good elasticity, and after especially adding endurable active toughener in epoxy resin, elasticity increases substantially.
Chinese patent CN101200053A reports the grinding tool of a kind of epoxy resin in conjunction with abrasive compound, comprise 15 ~ 78% epoxy resin, 2 ~ 44% abrasive material and 4 ~ 18% curing agent, abrasive material described in its Patent comprises one or more the above combinations in diamond, carborundum or corundum, curing agent comprises 4,4, one or more the combination in-methylene dianiline, solid diaminodiphenyl-methane or liquid modifying ~ amino ~ phenylmethane.The epoxy resin that this invention obtains can be applicable to various grinding-polishing equipment in conjunction with the grinding tool of abrasive compound.
Except resin types is to the diamond abrasive of diamond employing from sharp type, effectively can improve the stock-removing efficiency of grinding tool, Chinese patent CN1762660A reports a kind of preparation method of diamond resin grinding tool, the working lining of its feature technology mainly grinding tool is primarily of self-sharpening diamond abrasive material (12.5 ~ 31.25%, volume ratio, lower with), resinoid bond (40% ~ 50%), filler make (hard carbide of 5 ~ 15%, the hardening oxidation thing of 5 ~ 15% and 0 ~ 3% the additive of graphite composition), this invention grinding tool grinding efficiency is high, long service life.
