Abstract

The invention discloses a process for preparing a rubber compound of an ethylene propylene diene monomer waterproof roll. The process comprises the following steps: compounding, filtering rubber, yielding sheets, sulphurating and yielding strips. With the adoption of the manner, in the process for preparing rubber the compound of the ethylene propylene diene monomer waterproof roll, during sulphurating, an open mill is replaced with an internal mixer for sulphurating and compounding. A film cooling machine is used for guaranteeing timely and rapid cooling of the sulphurated rubber compound firstly in the industry, the quality of a prepared product is stable, linkage operation of the internal mixer, a rubber filter, a sheet-outputting machine and the film cooling machine, the energy consumption is reduced, the labor intensity of workers is reduced, the environmental pollution is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of preparation technology of mixed rubber for waterproof coiled material, in particular to a preparation process for mixed rubber for EPDM waterproof coiled material. Background technique [0002] Waterproof membranes are used in roofs, storage tanks, dams, subways, railway and highway tunnels, and tank linings for agricultural irrigation. They are used in large quantities. In the past, asphalt felt was the main material, but now rubber and plastic membranes are the main materials. EPDM waterproofing membrane has become a high-grade membrane due to its excellent material properties. [0003] The rubber compound in the waterproof membrane is the raw material for manufacturing the coil, that is, the semi-finished product. Therefore, the colloidal dispersion quality of the rubber compound is directly related to the quality of the finished product. At the same time, the viscoelasticity and rheology of the rubber compound ...
