Abstract
The present invention discloses a rubber anti-reversion agent, which comprises the following components in weight percentage: 42-55% of zinc fatty acid, 16-21% of poly zinc carbonate with branched chains, and 25-40% of petroleum resin. The above rubber anti-reversion agent is stable in performance. After the overvulcanization process, the rubber anti-reversion agent is low in themogenesis and high in stress retention rate at definite elongation.
Description
Technical field
The present invention relates to chemical field, be specifically related to a kind of rubber anti-recovery agent.
Background technology
Reversion refers to that sulfide cross-linked bond degradation causes vulcanized rubber physicals to decline, the phenomenon that use properties is deteriorated.Traditional sulfidation comprises sulfuration induction, pre-sulphur, plateau cure and over cure four-stage, in sulfuration inductive phase (time of scorch), be cross-linked and not yet start, sizing material has good mobility, this one-phase determines incipient scorch and the processing safety of sizing material, the terminal of this one-phase, sizing material lost flowability, and carry out the crosslinked arrival prevulcanized stage with certain speed, the crosslinking degree of prevulcanized phase is low, even if do not reach anticipation level to the intensity of later stage cross-linked rubber and elasticity yet, along with the growth of heated time, arrive the plateau cure stage, now the physicals of cross-linked rubber respectively close to or reach optimum point, or reach the overall equilbrium of performance, after the plateau cure stage, be the over cure stage, still preponderate if be cross-linked in this stage, rubber just hardens, tensile modulus continues to rise, otherwise, rubber feels like jelly, just there is reversion phenomenon.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention is: the rubber anti-recovery agent that a kind of dependable performance is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of rubber anti-recovery agent, it comprises the component of following weight percent: fatty acid zinc 42-55%, the many zinc carbonates 16-21% with side chain, petroleum resin 25-40%.
Further, described fatty acid zinc is Zinic stearas.
Further, described petroleum resin be aromatic resin, group aliphatic resin, alicyclic resin, hydrogenation resin one or more.
Beneficial effect: rubber anti-recovery agent stable performance of the present invention, has after over cure that heat-dissipating is low, stress at definite elongation conservation rate is high, resistance to fatigue good.
