Description

(1) Technical field

[0001] The invention relates to a waterproof coiled material and its production process, in particular to a modified asphalt self-adhesive waterproof coiled material and its production process. (2) Background technology

[0002] The existing modified asphalt self-adhesive waterproofing membrane generally contains the following components in its formula: 1) modified asphalt; 2) binder; 3) plasticizer; 4) filler, 5) other additives. Generally, natural binders such as rosin and modified rosin are added to the modified asphalt formula. The direct consequence is that the self-adhesive layer of the self-adhesive waterproof membrane has poor adhesion and low initial adhesion. The adhesiveness can only be increased by increasing the proportion of modified asphalt, which increases the cost and the adhesive effect is not good. The existing process for producing modified asphalt self-adhesive waterproofing membrane: the adhesive is treated with a colloid mill for 5...
