Production method of anti-cracking waterproof coiled material

The invention relates to the field of waterproof coiled materials, in particular to a production method of an anti-cracking waterproof coiled material, which is characterized in that asphalt layers are adhered to two sides of a tire base layer to prevent the coiled material from cracking; the process comprises the following steps: S1, adding raw materials into a reaction kettle, heating and mixing to obtain a melt; s2, adding the melt into a profiling device, and preparing an asphalt layer by using the profiling device; s3, the asphalt layers are adhered to the two sides of the tire base layer; and S4, the surfaces of the asphalt layers on the two sides are covered with surface films, and the anti-cracking waterproof coiled material is obtained. The profiling device comprises two side plates which are fixedly connected through two connecting plates, the lower portions of the two side plates are both connected with pressing wheel frames, pressing wheels are rotationally arranged at the inner ends of the two pr
