Abstract

The invention discloses a high and low temperature-resistant low-compression deformation colored vinyl acrylate rubber material and a preparation method thereof and belongs to the technical field of sealing rubber materials. The rubber material disclosed by the invention is prepared by sending vinyl acrylate rubber, 4, 4'-bis(phenylisopropyl) diphenylamine, a processing aid 18D, stearic acid, a processing aid VAM, white carbon black, ultrafine talcum powder, a softening and plasticizing agent TP-759 and phthalocyanine green into an internal mixer for internal mixing to obtain masterbatch; further sending the obtained masterbatch, 3-aminopropyl triethoxysilane, a cross-linking aid HMDC-1 and a curing agent 1, 8-diazabicyclo [5. 4. 0) undec-7-ene into the internal mixer together for performing two-section mixing, and discharging rubber when the temperature reaches 120 DEG C; and finally performing primary vulcanization and secondary vulcanization process for preparation. The preparation process is simple, and the high temperature resistance of the colored vinyl acrylate rubber is greatly improved; and meanwhile, the resistance to low temperature and the performance of low compression permanent deformation are also relatively excellent.

Description

technical field [0001] The invention relates to the technical field of sealing rubber materials, and more specifically relates to a green ethylene acrylate rubber material that not only meets the DaimlerChrysler standard DBL6038.50, but also has the characteristics of high and low temperature resistance, low pressure change, and environmental protection. Background technique [0002] Ethylene acrylate rubber has good high temperature resistance and lubricating oil resistance. DaimlerChrysler standard DBL6038.50 is easy to achieve for black ethylene acrylate rubber with carbon black as reinforcing filler. However, for colored ethylene acrylate rubber, it is difficult for colored ethylene acrylate rubber to have a strength greater than 10 MPa, and it is also difficult to have a lower Excellent compression set and good high and low temperature resistance.
