Resistance To The Refrigerant R134a Brominated Butyl Rubber Material Preparation

For resolving the ozone layer that the freon causes to break a problem, R134 is chosen as the refrigerant to replace freon currently, with the expansion and application of R134a, it request oil resistance, permeance resistance and age resistance of rubber in new cold system are better than rubber used in CFC system, therefore the demand make sure the new rubber material and the match principle. Because the bromination Butyl rubber material towards making a cold the R134a as to have lower of through rate, goodly heat-proof aging and the PAG oil function, last few years, bromination Butyl rubber material is used widely in Europe, America and Japan to apply extensively in the R134 as system the cold get in touch with mutually of work environment.According to the above reason, this topic turns the research that the match system of the bromination Butyl rubber, turning the vulcanized system of the bromination Butyl rubber to carry on a choice, through a great deal of experiment, making sure the sour salt amidocyanngen formic acid is a vulcanized agent, its characteristics is the physical machine function is high, bearing aging function and compress permanence to transform function good. Secondly, choice the compensation with fill the category of, carry on the contrast experiment, already certain in keeping with of the species and the dosage. Turn the premise that the Butyl gum anticipates the technique index sign in the contented bromine finally under, turn the Butyl rubber and 3 dollars B C rubber to counteract with the improvement craft function through a bromine, the exaltation produces an efficiency.The research expresses the bromination Butyl rubber material that bear the R134 meet the technique request as a result, it is a satisfied a local product and can reduce the dependence on importing.
