摘　　要：研究了退火温度和时间及退火后放置时间对橡塑开孔材料透水速率的影响。结果表明 :开孔材料透水速率随退火温度的升高而下降 ,退火温度越高 ,下降的幅度越大 ;同一退火温度下 ,透水速率随退火后放置时间的增长而降低 ,放置时间越长下降的幅度越大 ;透水速率随退火时间的增长而下降 ,退火时间越长 。This article mainly analyzes the effect of annealing temperature, time and shelf time on the water saturating rate of porous rubber thermoplastic blend system The results showed that the water saturating rate of the porous materials decrease with the increase of annealing temperature,the higher the annealing temperature,the more the rate decreased When the annealing temperature was the same,the water saturating rate decreases with the increase of the shelf time after the annealing,and the longer the shelf time,the more the rate decreased The water saturating rate decreased with the increase of annealing time,the longer the annealing time,the more the rate decreased
