Description
Technical field
The invention belongs to generator cushion blocking glue production technical field, be specifically related to high-performance rubber and preparation technology thereof for a kind of generator cushion blocking.
Background technology
Develop rapidly along with modern industry, the power of generator is increasing, the harm of vibrations and noise is also more and more outstanding, now widely used method is to utilize elastomeric material and framework material (as metal, fiber, engineering plastics etc.) compounded vibroshock or special rubber visco-elasticity high damping material are eliminated the vibratory impulse of vibration source and are absorbed noise, generator is because long term operation produces amount of heat, require the cushion blocking of generator to there is high strength by rubber electrodes, high elongation rate, high-wearing feature, high temperature resistant, avoid occurring thermal ageing, but the performance of yielding rubber still can not meet the demand of generator at present, cause annual glue consumption huge.
Yielding rubber was used after for some time, rubber hardening, shockproof properties variation, reason: 1. sulfur-crosslinked mode changes disulfide linkage and monosulfidic bond into and makes cross-linking density increase by gathering sulfide linkage; 2. rubber sclerosis itself worsens; What 3. by sulfur sulfurizing agent, produced is crosslinked etc.At present long by form single sulfide enrichment crosslinked form, add protective agent or the methods such as the combined amount of sulfur sulfurizing agent reduces as much as possible solved, but can not suppress fully the sclerosis of rubber after life-time service (thermal ageing), shockproof properties worsens.
Application number is 200410104741 invention < < vibration damping rubber composition > >, vulcanizing agent adopts specific bismaleimide compound, do not contain sulphur, to suppress the sclerosis of rubber after life-time service.But bismaleimide compound activity is higher, in sulfidation, easily participate in crosslinking reaction, consume the free radical of the vulcanization accelerator of part, postpone rubber mass curing time; Bismaleimide compound molecular structure is rigidity, and add-on surpasses 1 part, can be uneven because disperseing in rubber mass, in drawing process, produce stress concentration, and can obviously reduce the breaking tenacity of rubber mass; During sulfuration, just do not produce and be cross-linked, also the effect due to heat and other factors produces Congress of Industrial Organizations's chain and molecule chain break.Bismaleimide compound can significantly improve the cross-linking efficiency of peroxide vulcanizing system, excessive if crosslinked institute preponderates, and rubber is will hardness higher.Gained vibration damping rubber composition hardness is higher, and breaking tenacity and elongation at break are on the low side, and it is limited that over-all properties strengthens degree.In addition, bismaleimide compound good heat resistance, vulcanization rate is slower, and sulfuration requires to carry out at higher temperature; Bismaleimide compound price is also more expensive, so at present still only as crosslinking coagent, add on a small quantity, to realize the high-speed vulcanization of rubber.
Summary of the invention
The present invention is in order to make up the deficiencies in the prior art, and high-performance rubber and preparation technology thereof for a kind of generator cushion blocking is provided, and this rubber has good breaking tenacity and elongation at break and suitable hardness, and resistance to elevated temperatures is excellent, good damping effect.
A generator cushion blocking high-performance rubber, its raw materials used comprising: 100 parts of natural rubbers, 0.1～0.2 part of peptizer DBD, 4～5 part of 100 order zinc oxide, 0.9～1.1 part of stearic acid, 0.2～0.3 part of anti-scorching agent CTP, 28～32 parts of spray carbon blacks, 2.5～3.5 parts of vulcanizing agent DCP, 0.5～0.6 part of accelerant B MI, 0.6～0.7 part of mphenylenediamine, 0.1 part of bisphenol A type epoxy resin, 0.1～0.2 part of Vulcanization accelerator TMTD, 0.1 part of accelerant CZ; Described part refers to mass parts.
