Abstract

The present invention relates to a preparation method of anti-corrosion self-adhesive polymer modified bitumen waterproof coiled material, step S1, prepare jelly; step S2, prepare modified asphalt layer; step S3, control unit start spraying device The obtained jelly is sprayed on the modified asphalt layer in the step S2 to form a sprayed layer, and when sprayed to a preset thickness, an adhesive layer is obtained; in step S4, the adhesive layer in the step S3 is coated with PET Film, drum leveling, coiling, sealing and packaging; the control unit compares the actual spraying layer increasing thickness with the preset spraying layer increasing thickness, and adjusts the spraying times of the spraying assembly and the rotation of the driving assembly according to the comparison result Speed, through the control unit to precisely control the spraying process, so that after each spraying, the growth thickness of the sprayed layer meets the preset standard. While improving the spraying efficiency, it can effectively avoid material waste and further ensure waterproofing The quality of the coil.

Description

technical field [0001] The invention relates to the technical field of waterproof rolls, in particular to an anti-corrosion self-adhesive polymer-modified bitumen waterproof roll and a preparation method thereof. Background technique [0002] The waterproofing membrane is mainly used for building walls, roofs, tunnels, highways, garbage disposal sites, etc., and is a flexible building material product that can be rolled into a roll to resist the leakage of external rainwater and groundwater. The non-leakage connection between buildings is the first barrier of waterproofing of the whole project and plays a vital role in the whole project. [0003] During the preparation process of the existing waterproofing membrane, it is impossible to control the spraying process of the sticky layer in real time, resulting in uneven spraying of the sticky layer, resulting in waste of jelly, reducing the service life of the waterproofing membrane, and reducing the waterproofing membrane. qu...
