Description
Technical field
The invention belongs to rubber shock-absorbing field, be specifically related to a kind of warping strength yielding rubber.
Background technology
The natural high moleculer eompound of natural rubber to be a kind of with polyisoprene be main component, dynamic lag loss is few, and heat-dissipating is low, has good sealing property and dynamic flexing performance; Anti-form-1,4-polyisoprene (TPI) trans content up to 98%, because its trans purity is higher, at room temperature in crystal form, its second-order transition temperature is about-60 DEG C, and with natural rubber, cis-1,4-polybutadiene rubber use, its rubber unvulcanizate shows excellent warping strength characteristic.Yielding rubber material is widely used in the position such as lathe, vehicle, plays the effect of damping, buffering, shock insulation, requires that yielding rubber material has heat-resisting, warping strength performance preferably.The how easy premature aging of yielding rubber material now used, to deflect performance bad, causes cushioning material to break and lose damping effect.
Summary of the invention
The object of the present invention is to provide a kind of warping strength yielding rubber.Technical scheme of the present invention is: a kind of warping strength yielding rubber, counts by weight, comprises following material: natural rubber 90 ~ 100 parts, anti-form-1,4-polyisoprene 10 ~ 20 parts, promoting agent 6 parts, strengthening agent 40 ~ 45 parts, nano imvite 5 ~ 15 parts, 2 ~ 4 parts, anti-aging agent, scorch retarder 0.3 part, processing aid 2 parts, silane coupling agent 1 ~ 3 part, 1.5 ~ 3 parts, sulphur, promotor 0.5 ~ 3 part.
By parts by weight, to be the zinc oxide of 5 parts and parts by weight be described promoting agent that the stearic acid of 1 part forms.
Described strengthening agent is made up of carbon black N330, white carbon black, and described silane coupling agent is Si-69; The also use of white carbon black, silane coupling agent and carbon black N330, not only reaches the physical mechanical strength required by rubber, and the wear resisting property improving cross-linked rubber adds the autohension of rubber unvulcanizate simultaneously; Nano imvite belongs to layered silicate non pinetallic nano mineral substance, deflects performance with carbon black and with what can increase vulcanization of rubber glue.
4020 and RD that described anti-aging agent is 2:1 by ratio of weight and number form, and antioxidant 4020 belongs to p phenylenediamine type antioxidant, have to resist preferably to deflect be full of cracks performance and good antioxidant property; Anti-aging agent RD belongs to the anti-aging agent of quinoline, has good protection effect to heat and the aging of oxygen; These two kinds of anti-aging agent synergies, can reach optimum protection effect in the formula of rubber.
Described scorch retarder is CTP, and scorch retarder CTP adds the stability increasing rubber mixed processing characteristics.
Described processing aid is Microcrystalline Wax.
Described promotor is sulfenamide type accelerators.The also use of sulfenamide type accelerators and sulphur, can make rubber unvulcanizate have more smooth vulcanization curve, give cross-linked rubber good over-all properties simultaneously.
Beneficial effect of the present invention is: the deflecting standard pattern and can accomplish not occur for 300,000 times be full of cracks of warping strength yielding rubber, the pure glue damping sample using this formula to produce can be accomplished not rupture for 2,400,000 times, has good application for the resistance to higher product of damping requirement of subduing.
