Abstract
The invention discloses a REPDM/RIIR/POE (reclaimed ethylene propylene diene monomer/reclaimed isobutylene-isoprene rubber/polyolefin elastomer) and a preparation method thereof, relating to an elastomer material and a preparation method thereof. The REPDM/RIIR/POE mainly comprises the following components in parts by mass: 100 parts of REPDM and RIIR in combination, 1-2 parts of sulfur, 0.9-2 parts of accelerant, 2.5-8 parts of vulcanizing activator and 0-20 parts of carbon black. According to the invention, the REPDM and the RIIR completely replace EPDM and IIR, thereby reducing the cost of a waterproof material and simplifying the processing process. The REPDM is used as a main body, and the RIIR and the POE are partially added to realize excellent resistance against heat aging and ultraviolet rays. The POE is similar to the EPDM and the IIR in structure, and good processability is realized by combining the three, therefore, the REPDM/RIIR/POE with excellent comprehensive performance such as long service life, cold resistance, weather resistance, ozone resistance, hot-air aging resistance and the like can be obtained and is applied to the waterproof material.
Description
Technical field
The present invention relates to a kind of elastomer material and preparation method thereof, particularly relate to a kind of REPDM/RIIR/POE elastomerics and preparation method thereof.
Background technology
