摘　　要：通过添加过氧化氢或过碳酸钠考察废胶粉再生过程中氧化程度对再生橡胶性能的影响。结果表明:废胶粉再生配方中添加过氧化氢或过碳酸钠后,再生橡胶的溶胶质量分数增大,门尼粘度下降,强伸性能有所改善;综合考虑再生橡胶的加工性能和强伸性能,过氧化氢用量以0.7份为宜,过碳酸钠用量以1.8份为宜,过碳酸钠的再生效果更好。The effect of oxidation degree of wasted rubber powder during the reclamation on the properties of reclaimed rubber was investigated by adding hydrogen peroxide or sodium percarbonate. The results showed that,with addition of hydrogen peroxide or sodium percarbonate in the waste rubber powder regeneration formula,the sol fraction in the reclaimed rubber increased,Mooney viscosity decreased,and tensile properties were improved. Considering the processing and tensile properties of reclaimed rubber,the suitable amounts of hydrogen peroxide and sodium percarbonate were 0.7 phr and 1.8 phr,respectively,and sodium percarbonate possessed better regeneration result.
