摘要
研究硫化橡胶低温脆性的测定方法。试样裁切方向会影响硫化胶脆性温度的测定结果。建议在GB/T 1682—2014修订时应该考虑试样裁切方向和试样冷冻期间搅拌的影响。明确了在给定脆性温度限值时的试验结果判定方法,对橡胶制品的低温脆性检测具有一定的指导意义。
The determination method of the low temperature brittleness of vulcanizates was studied.The cutting direction of the sample would affect the measurement results of the brittleness temperature of the vulcanizate.It was suggested that the influence of cutting direction of sample and stirring during freezing should be considered in the revision of the national standard GB/T 1682—2014.The method of judging the test results at the given limit of brittleness temperature was defined,which was of certain significance for the low temperature brittleness detection of rubber products.
