Embodiment 1
[0022] In this example, the vulcanization system used is composed of sulfur, TMTD, and DM. The vulcanization activator is zinc oxide and stearic acid. 5 parts of zinc, 3 parts of stearic acid, 1.5 parts of sulfur.
[0023] The RIIR / REPDM elastomer described in this embodiment, its preparation steps:
[0024] a. First pass RIIR and REPDM on the mill for several times to mix them evenly, then add zinc oxide and stearic acid, add accelerator after mixing evenly, and finally add sulfur; then pack the mixed rubber 10 times, mix Discharge evenly and store for 24 hours for use;
[0025] b. Return the film that has been parked for 24 hours and reload it for later use;
[0026] c. Put the remixed rubber in step b on a flat vulcanizer for vulcanization, the temperature is controlled at 160°C, and the t is measured with a rubber rotorless vulcanizer during vulcanization. 10 and t 90 ,M L and M H (The test results of each example are shown in Table 1); after the time is reached, the...
Embodiment 2
[0029] The difference between this example and Example 1 is that the type of accelerator has been changed, and the specific formula is: 90 parts of RIIR, 10 parts of REPDM, 1.5 parts of TMTD, 0.5 parts of M, 5 parts of zinc oxide, 3 parts of stearic acid, and 1.5 parts of sulfur share. Table 2 shows the mechanical property test results of the RIIR / REPDM elastomer described in this example.
Embodiment 3
[0031] The difference between this example and Example 1 is that the type of accelerator is changed, and the specific formula is: 90 parts of RIIR, 10 parts of REPDM, 1.5 parts of BZ, 0.5 parts of DM, 5 parts of zinc oxide, 3 parts of stearic acid, and 1.5 parts of sulfur share. Table 2 shows the mechanical property test results of the RIIR / REPDM elastomer described in this example.

Abstract
An RIIR / REPDM elastomer and a preparation method thereof, relating to a regenerated butyl rubber and a preparation method thereof, the waterproof material RIIR and REPDM are combined with a total amount of 100 parts, 1-2 parts of sulfur, and 0.9-2 parts of an accelerator. 2.5-8 parts of vulcanization active agent, 0-20 parts of carbon black. Both RIIR and REPDM have good process compatibility. Adding part of REPDM to RIIR can not only obtain better comprehensive performance, but also improve the machinability of RIIR. The two glues can use the same vulcanization system, and the vulcanization rate is relatively close, and it is easy to form co-vulcanized materials. The present invention uses RIIR and REPDM to completely replace EPDM and IIR, which reduces the cost of waterproof materials, improves the adhesion between waterproof materials and substrates, and makes the RIIR / REPDM waterproof materials obtained in the final research have ozone resistance, weather resistance, and Low temperature, chemical medium resistance, heat air aging resistance and other excellent properties.
Description
technical field [0001] The invention relates to a regenerated rubber and a preparation method thereof, in particular to a RIIR / REPDM elastomer and a preparation method thereof. Background technique [0002] Leakage in buildings has always been a major problem in my country's construction industry. At present, the leakage rate of houses in our country is very high, mainly due to the low grade and poor quality of waterproof materials and the prevalence of counterfeit products. Therefore, there is a great demand for high-performance waterproof materials in our country, but it is difficult to popularize high-performance waterproof materials in the construction industry due to cost problems. In recent years, with the rapid development of my country's automobile industry, the output of RIIR has also increased. RIIR has the characteristics of heat resistance, aging resistance and water resistance. In order to avoid wasting precious rubber resources, it becomes especially importan...
