Dip-coating process and dip-coating system for padding waterproof roll

Abstract

The invention relates to the technical field of production of waterproof rolls with tires and discloses a dip-coating process for a padding waterproof roll. The process comprises the steps of performing asphalt dip-coating on a tire base cloth to prepare a padding waterproof coiled material, coating a surface of a padding base cloth with the asphalt or soaking the padding base cloth into the asphalt to enable the asphalt to cover the surface of the padding base cloth, and then extruding the padding base cloth with the surface coated with the asphalt in the direction forming an acute angle withthe vertical direction. The invention further discloses a dip-coating system for the padding waterproof roll. The system comprises a dip-coating pool used for containing asphalt and performing dip-coating on the padding base cloth with the asphalt, and an extrusion device which is arranged above the dip-coating pool and is used for extruding the padding base cloth which is subjected to the dip-coating with the asphalt; the extrusion device comprises at least two extrusion rollers; the rotating shafts of every two adjacent extrusion rollers are parallel to each other and are not located in thesame vertical plane, the padding base cloth penetrates into a gap between every two adjacent extrusion rollers from lower sides of the two adjacent extrusion rollers after being subjected to the dip-coating with asphalt in the dip-coating pool, and the asphalt extruded to run to the two sides can be received by the padding base cloth again and cannot be attached to the extrusion rollers.

Description

technical field [0001] The invention relates to the technical field of production of waterproof coiled materials with tires, and more particularly relates to a dip-coating process and system for waterproof coiled materials with tires. Background technique [0002] Asphalt waterproofing membrane refers to a roll material made of asphalt material, tire material and anti-adhesive material spread on the surface, also known as linoleum, which is often used for pasting waterproof layers. Bitumen waterproofing membranes include tire membranes and tireless membranes. Any roll-shaped material made of thick paper or glass cloth, asbestos cloth, cotton and linen fabrics and other tire materials impregnated with petroleum asphalt is called tire-shaped roll material; asbestos, rubber powder, etc. are mixed into the asphalt material, and after rolling The resulting roll material is called a rolled roll, that is, a tireless roll. Asphalt waterproofing membrane has low cost, low tensile s...

AI Technical Summary

Problems solved by technology

Although it can play the role of extruding the tire base cloth, since the driving roller 61, the extruding fixed roller 62 and the extruding moving roller 63 are arranged on the same vertical plane, the action point of extruding is located in the lower middle of the two adjacent rollers. At the highest point of the set roller, the asphalt extruded during extrusion will flow to both sides of the extrusion point, and the roller surface on the side not covered by the tire base cloth on the lower set roller will flow The flowed asphalt adheres to the roller, and when the viscosity of the asphalt is high, it will also affect the extrusion of the subsequent tire base fabric, resulting in obvious potholes on the surface of the extruded tire base fabric, which eventually leads to the appearance of the finished product. Bubbles, white spots on the surface, poor water impermeability, low peel strength
