Dip dyeing process for asphalt on surface of waterproof roll

Abstract

The invention relates to a dip dyeing process for asphalt on the surface of a waterproof roll. The dip dyeing process includes the following process steps: an unwinding process: rotationally arranging a cloth winding disc wound with base cloth on a winding disc support, and leading out one end of the outer side of the base cloth from the cloth winding disc to bypass the upper part of a pre-tightening wheel; a cloth winding process: putting asphalt paint used for dip-dyeing the base cloth in a dip-coating pool, and driving a first rotating shaft in a horizontal state by a servo motor to rotate in a first mounting block through a transmission mechanism; a dip dyeing process: driving the first rotating shaft by a servo motor to gradually rotate downwards from the horizontal state to a maximum inclination angle state with a sixth rotating shaft as an axis, and then gradually rotate upwards from the maximum inclination angle state to the horizontal state; and a press-fitting process: driving the first rotating shaft in the horizontal state by the servo motor through the transmission mechanism to rotate in the first mounting block, and synchronously winding the tire base cloth by a dip-coating roller. According to the process, the dip dyeing effect between the base cloth and the asphalt on the surface of the base cloth is improved, so that the waterproof effect and the overall strength of the waterproof roll are improved.

Description

technical field [0001] The application relates to the technical field of production of waterproof coiled materials, in particular to a dip-dyeing process of asphalt on the surface of waterproof coiled materials. Background technique [0002] As the country increases the scale of investment in new infrastructure, the demand for waterproof materials for construction projects is also increasing, and the requirements for quality are also getting higher and higher. With the delivery and use of various engineering constructions, the problem of water seepage and leakage in roofs, floors, and basements has always plagued people. As a result, waterproof projects have emerged as the times require. Various waterproof materials emerge in endlessly, and waterproof membranes are widely used in the construction industry. Among them, the asphalt waterproof membrane is an important waterproof building material, which is a rolled material made of asphalt materials, tire materials, and anti-st...

AI Technical Summary

Problems solved by technology

[0003] At present, the production process of asphalt waterproof coiled material is usually to dip-coat asphalt on the surface of the base fabric such as non-woven fabric, and then perform elastic extrusion on the base fabric dipped in asphalt to make the asphalt compact on the base fabric, but In the prior art, the asphalt dipping method on the surface of the tire base cloth is unreasonable, and the uniformity and bonding strength of the surface asphalt are not high, resulting in a poor dipping effect between the asphalt and the tire base cloth, so that the prepared asphalt The tensile strength and tear strength of the waterproof membrane are not high
