Abstract

The invention relates to a preparation method of an anti-corrosion self-adhesive polymer modified asphalt waterproof coiled material. The preparation method comprises the following steps: S1, preparing jelly; S2, preparing a modified asphalt layer; S3, starting a spraying device by the control unit to spray the jelly obtained in the step S1 on the modified asphalt layer in the step S2 to form a spraying layer, and when the spraying layer is sprayed to a preset thickness, obtaining an adhesive layer; and S4, applying a PET film to the adhesive layer in the step S3, and flattening, through a roller, and coiling the adhesive layer, and packaging the adhesive layer in a sealed mode. The control unit compares the actual spraying layer increasing thickness with the preset spraying layer increasing thickness, the spraying frequency of the spraying assembly and the rotating speed of the driving assembly are adjusted according to the comparison result, the spraying process is precisely controlled through the control unit, and therefore the increasing thickness of the spraying layer meets the preset standard after spraying every time, while the spraying efficiency is improved, the waste of materials can be effectively avoided, and the quality of the waterproof coiled material is further ensured.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled material, in particular to an anti-corrosion self-adhesive polymer modified asphalt waterproof coiled material and a preparation method thereof. Background technique [0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, garbage cleaning sites, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis and There is no leaky connection between buildings, which is the first barrier for the waterproofing of the whole project and plays a vital role in the whole project. [0003] During the preparation process of existing waterproof membranes, the spraying process of the adhesive layer cannot be controlled in real time, resulting in uneven spraying of the adhesive layer, resulting in waste of jelly, reducing the service life of waterproof membranes, and reducing the qual...
