Secondary coating equipment for asphalt waterproof coiled material

Abstract

The invention relates to the technical field of asphalt waterproof coiled material production equipment and discloses secondary coating equipment for an asphalt waterproof coiled material. The equipment comprises a drying device and a coating device which are arranged in sequence, the drying device comprises two drying rollers which are arranged at an interval and are independently driven, and thetwo drying rollers are a first drying roller and a second drying roller which have heat; the coating device comprises a coating pool used for containing and / or bearing asphalt and a double-straight-row extrusion forming mechanism arranged above the coating pool. The double-straight-row extrusion forming mechanism comprises two pairs of extrusion rollers which are arranged at intervals, have heatand are arranged in pairs, the two pairs of extrusion rollers are a first upper extrusion roller and a first lower extrusion roller which are used for rough pressing and a second upper extrusion roller and a second lower extrusion roller which are used for fine pressing, and the rotating speed of the first upper extrusion roller is larger than that of the second upper extrusion roller. The mode ofcombining drying and coating is adopted, through improvement of the multiple drying devices and the coating device, the multiple drying devices and the coating device better adapt to each other, andtherefore the quality of a finished waterproof coiled material is promoted to be improved.

Description

technical field [0001] The invention relates to the technical field of asphalt waterproof coiled material production equipment, and more specifically, relates to a secondary coating equipment for asphalt waterproof coiled material. 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. [0003] Modified asphalt waterproofing membrane is commonly ...
