Production method of polyvinyl chloride waterproof coiled material

Abstract

The invention relates to a production method of a polyvinyl chloride waterproof coiled material. A pasting device is used in the method and comprises a base, a winding and unwinding device, a gluing device, a laminating device and an alignment table. According to the winding and unwinding device, by starting a driving motor, the output end of the driving motor drives a material winding rotating shaft to rotate, and rotation of the material winding rotating shaft drives a material winding roller to rotate, thus achieving unwinding, adhesion and winding of a separation film roll and a waterproof layer roll. According to the laminating device, after an extrusion motor is started, the output end of the extrusion motor drives a center shaft to rotate, the center shaft drives a gear to rotate when rotating, and therefore, two extrusion rollers do repeated opposite movement and relative movement along the middle part of the laminated coiled material, so that bubbles and redundant glue in the laminated waterproof coiled material can be extruded out.

Description

technical field [0001] The invention relates to the technical field of polyvinyl chloride coiled material, in particular to a production method of polyvinyl chloride waterproof coiled material. Background technique [0002] Polyvinyl chloride is a polymer formed by the polymerization of vinyl chloride monomers in peroxides, azo compounds and other initiators or under the action of light and heat according to the mechanism of free radical polymerization; [0003] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis There is no leakage connection with the building. It is the first barrier for the waterproofing of the whole project and plays a vital role in the whole project. There are many kinds of waterproof rolls. The common self-adhesive waterproof rolls are made of isolation The waterproo...

AI Technical Summary

Problems solved by technology

[0005] (1) When laminating the isolation membrane and the waterproof layer roll cloth, since the waterproof roll material is rolled up during production and spread out, the length of the roll material during processing is too long, and the existing device cannot realize Unwinding, gluing, and rewinding cannot be realized simultaneously during waterproofing membrane processing;

[0006] (2) The existing device cannot glue the waterproof membrane when it is pulled forward according to the waterproof roll cloth, which causes troubles in processing;

[0007] (3) When processing the waterproof membrane, the two layers of the membrane will produce air bubbles after the glue is applied and the excess glue cannot be discharged, which will affect the quality of the waterproof membrane
