一、前言:当前,我国平顶屋面的保温层一般采用内隔热法设置,屋面防水层广泛使用黑色或深色沥青基防水村料,这样,在太阳光的强烈照射下屋面由于黑体吸热产生异常高温,造成居住和使用条件低劣,并且会加速防水层的老化,致使沥青基屋面防水层逐渐失去弹塑性并导致屋面防水层最后龟裂和剥落。 I. Preface: At present, the insulation layer of China’s flat-roof roof is generally set by the internal heat insulation method, and black or dark asphalt-based waterproof village materials are widely used in the roof waterproof layer. In this way, due to the intense sunlight, the roof is endothermic due to black body. The generation of abnormally high temperatures results in poor conditions of residence and use, and will accelerate the aging of the waterproof layer, resulting in gradual loss of elasticity of the waterproof layer of the bitumen-based roof and subsequent cracking and peeling of the waterproof layer of the roof.
