Specific embodiment
The present inventor in order to be able to preferably understand technical scheme, below by specifically real
Example is applied, is described in detail：
A kind of wet and heat ageing resistant rubber for automobile engine connecting bushing of the invention has resistance to high humidity and is difficult old
The characteristics of change.
In order to reach above-mentioned purpose, the present invention first has to select suitable rubber raw material, improves the wet and heat ageing resistant of rubber
The wet-hot aging performance that it is critical only that raising rubber molecule main chain section of performance, it is critical only that the homopolymerization again for improving rubber raw material
Degree, and the molecular weight dispersion coefficient of rubber raw material is leveled off to 1.Weight average degree of polymerization is high, molecular weight dispersion coefficient level off to 1 life
Even if collagen material occurs backbone breaking, degree of deflecting and good viscoplasticity higher is still can guarantee that.Isoprene rubber and natural rubber
The polymerized monomer of glue is isoprene, but isoprene rubber as a result of Ziegler-Natta polymerization technique, therefore its heavy homopolymerization
Right higher than natural rubber, molecular weight dispersion coefficient ratio natural rubber more levels off to 1, and side chain is less, therefore humidity resistance
Can be more excellent.But isoprene rubber yield strength and tensile strength are lower than natural rubber, therefore using isoprene rubber and natural rubber
Used as in rubber raw material, and rubber raw material, the weight accounting of isoprene rubber is 55%~70% to blend, natural rubber material
Accounting is 30%~45%, and the wet-hot aging performance of rubber can be so improved while rubbery intensity is not reduced.
Secondly the reinforcing agent that selection coordinates with rubber raw material, the effect of reinforcing agent is to improve the connection between molecule segment
Intensity, and optimize the vulcanizing system and protection system of rubber, improve vulcanization effect and wet and heat ageing resistant performance.In current rubber often
Reinforcing agent is carbon black and white carbon.White carbon also known as nano silicon, therefore compared to carbon black, white carbon surface area
Greatly, particle diameter is smaller, and activity is high, and with white carbon as reinforcing agent, the rubber tensile intensity and tearing strength after vulcanization are high, heat resistance
Can more preferably, but elasticity can be reduced, and white carbon and carbon black share the problem that can improve caoutchouc elasticity reduction after vulcanization.It is simultaneously white
The siloxanes or silanol of carbon blacksurface are big with the Chemical bond energy that silane coupler is formed, not easy to break, and can drop
The self heat generation of rubber after low-sulfur, so as to improve the wet-hot aging performance of rubber.
3rd, age resistor is TMQ, i.e., 2,2,4- trimethyl -1,2- dihyaroquinolines condensate and IPPD, i.e. cumene
Base p-phenylenediamine is used in combination, improve after vulcanization rubber is heat-resisting, resistance to ozone and it is anti-deflect cracking performance, while being disperseed using activation
