高衰减叠层橡胶具有衰减性大,剪切弹性模量低,在长期反复经受剪切变形的条件下剪切弹性模量提高不多及长期稳定性好等特征。这种高衰减支承体用胶料是在100份二烯类橡胶中配合50~90份炭黑,5~45份石油树脂。炭黑的氮吸附比表面积(N2SA)为150~300 m2/g,DBP吸油值在115cm3/100g以下,氮吸附比表面积(N2SA)和溴代十六烷基三甲胺吸附比表面积(CTAB)之差为5~34m2/g。高衰减支承体由高衰减胶料和硬质板材交替叠层经模压而成。
High attenuation laminated rubber has the characteristics of large attenuation, low shear modulus of elasticity, little increase of shear modulus and long-term stability under long-term repeated shear deformation. The high attenuation carrier rubber is prepared by blending 50 to 90 parts of carbon black and 5 to 45 parts of petroleum resin with 100 parts of diene rubber. The carbon black has a nitrogen adsorption specific surface area (N2SA) of 150-300 m2 / g, a DBP oil absorption of less than 115 cm3 / 100 g, a nitrogen adsorption specific surface area (N2SA) and a bromocetyl trimethylamine adsorption specific surface area The difference is 5 ~ 34m2 / g. High attenuation of the body by the high attenuation of rubber and hard plate alternately laminated molded.
