Embodiment

[0006] Example: A preparation process of a polymer elastomer rubber waterproofing membrane. Recycled rubber, asphalt, light calcium carbonate, active agent, 481 reinforcing agent, antioxidant, and accelerator are mixed, and the process is carried out with a sealed kneader Stirring and kneading; sending the kneaded rubber to the laminating machine for back pressure to make the mixing more uniform; sending the back pressed rubber and the lower sheet to the three-roll calender for cold pressing, sheeting, Curl, shape, and pack.

Abstract

The present invention relates to a preparation technology of macromolecule elastomer rubber waterproof membrane; reclaimed rubber, asphaltum, light calcium carbonate, promoting agent, 481 strengthening agent, age inhibitor and accelerant are mixed, and then milled and pressed by a sealed pressing machine; rubber material after being pressed is delivered to a rubber pressing machine for a return press, rubber material can be mixed more evenly; the lower chip of the rubber material after the return press is delivered to a three roll calender for cold pressing, outputting chip, curling, molding and packing. The present invention has the advantages of no three wastes discharged during the whole production, good in compactability and service performance, no air bubble, holes and corrugation produced, as well as single-layer construction, cold working, light weight, aging resistance, long service life, good tensile-strength and percentage of elongtation, strong adaptability for the constriction, craze and fission of the grass root, no embrittlement cracking in low temperature and no aging in high temperature.

Description

Technical field [0001] The invention relates to a preparation process of a polymer elastomer rubber waterproof coiled material. Background technique [0002] At present, the use of vulcanization to produce modified recycled rubber waterproofing membranes has the disadvantages of air pollution, waste of energy, labor and time. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects and provide a process for preparing a polymer elastomer rubber waterproof roll. [0004] The technical scheme of the present invention is: a preparation process of a polymer elastomer rubber waterproof roll material, which is characterized in that: reclaimed rubber, asphalt, light calcium carbonate, active agent, 481 reinforcing agent, antioxidant, and accelerator are mixed , Use a sealed kneader for mixing and kneading; send the kneaded rubber to the rubber press for back pressure to make the mixing more uniform; send the back pressed rubber to...
