Abstract

The invention relates to gluing technologies of macromolecule co-mixing forming machines, and discloses an integrated forming technology of macromolecular sheet production and gluing. The technology comprises the steps of material mixing, extrusion of raw materials of macromolecules and glue, co-extrusion, direct coating of isolating membranes, and the like. According to the technology, sheet production and gluing are integrated, the production technology process is greatly simplified, a three-roll calendaring device, a traction and winding device and an unwinding device are decreased, a sheet and glue are compounded in the thermal state, the sheet and the glue are bonded more firmly and do not separate from each other, secondary heating of the glue is avoided, the energy consumption is reduced, the resources are saved, the labor cost is reduced, the controllability of the production steps is strengthened, the performance of a produced coiled material is higher, the continuous production can be achieved, and the stability is higher.

Description

Technical field [0001] The invention relates to a glue coating process of a polymer blending molding machine, in particular to a polymer sheet and glue coating integrated molding process. Background technique [0002] Polymer self-adhesive coiled materials (including waterproof coiled materials and building floor adhesive sheets and coils) are composed of polymer sheets, self-adhesive layers and isolation membranes, and can be reinforced with composite fabrics on the polymer sheets as needed; The coiled material combines the advantages of polymer waterproof coiled material and self-adhesive coiled material, which greatly improves the performance of puncture resistance, weather resistance, self-healing, high and low temperature resistance, and has better physical properties and more stable chemical properties. The new polymer self-adhesive waterproofing membrane can be permanently bonded to the concrete structure layer to form a "skin-like" waterproof structure without the hidden ...
