The rubber composition provided in the invention has low permanent compression deformation; and the composition is used for fabricating rubber products like sealing rings, having the advantages of conservation of cost and excellent performance.
Description
Technical field
The present invention relates to the rubber combination field, exactly is a kind of rubber combination with low compression set characteristic.
Background technology
Paracril claims divinyl one acrylic-nitrile rubber again, is called for short NBR, molecular-weight average about 700,000.Pearl to light yellow bulk or powdery solid, specific density 0.95～1.0.Acrylonitrile content is one 52 ℃ of 26% paracril second-order transition temperature Tg=, one 47 ℃ of embrittlement temperature Tb=, and acrylonitrile content is one 22 ℃ of 40% paracril second-order transition temperature Tg=.SP δ=8.9～9.9 are dissolved in vinyl acetic monomer, N-BUTYL ACETATE, chlorobenzene, methylethylketone etc.Paracril has excellent oil resistance, and its oil-proofness is only second to thiorubber and viton, and wear resistance that has and resistance to air loss.The shortcoming of nitrile rubber is not anti-ozone and aromatic series, halohydrocarbon, ketone and esters solvent, is unfit to do insulating material.Thermotolerance is superior to X 050, X 050, can be 120 ℃ of long term operations.Resistance to air loss is only second to butyl rubber.The performance of paracril is influenced by acrylonitrile content, improve along with acrylonitrile content increases tensile strength, thermotolerance, oil-proofness, resistance to air loss, hardness, but elasticity, winter hardiness reduces.Paracril ozone resistance and electrical insulation capability are not good.And existing sealing-ring goods require it to have lower compression set.
