摘　　要：为阻隔墙壁内的氡,减少其对人体的危害,研究了辐射对丙烯酸面漆的交联作用,提出研制防氡涂料的新方法。利用γ射线对涂料进行照射,设置吸收剂量为1、2、3、4、5、6、7、8、9、10kGy,探索了不同吸收剂量对涂料的交联作用。结果表明,当吸收剂量小于2kGy时,涂料交联作用随吸收剂量的增加而加强,相应的防氡效率也逐渐增加;当吸收剂量为2kGy时,防氡效率达到最大值,为67.3%;当吸收剂量大于2 kGy时,交联作用随着吸收剂量的增加而逐渐降低,涂料的防氡效果也越来越差。The cross-linking effect of radiation on acrylic paint was investigated in order to block the emission of radon from walls and to reduce its harmful influence on the human body. As a result, a new method is proposed for the development of an anti-radon coating. The investigated coating was irradiated with gamma-rays, and the absorbed dose was in the range of 1 to 10 kGy in increments of 1 kGy. Subsequently, the cross-linking effect of the different absorbed doses on the coating was examined. The results indicated that when the absorbed dose was less than 2 kGy, the cross-linking effect of the coating increased with the absorbed dose, and the corresponding radon prevention efficiency also gradually increased. An absorbed dose of 2 kGy resulted in a maximum value of 67.3% for the flood prevention efficiency. In the case when the absorbed dose was more than 2 kGy, the cross-linking effect gradually decreased with an increase in the absorbed dose, and the anti-radon effect of the paint progressively deteriorated.
