The invention discloses a reaction force plate for an automotive electronic booster and a manufacturing method thereof. The reaction force plate comprises the following raw material components in parts by mass: NBR with low acrylonitrile content: 70-100 parts, common acrylonitrile content NBR: 0-30 parts, wear-resistant carbon black: 30-60 parts, semi-reinforced furnace black: 30-60 parts, zinc oxide: 5 parts, anti-aging agent: 1-4 parts, processing aid: 0.5-1.5 parts parts, anti-scorch agent: 0.2-1 part, tackifying resin: 1-7 parts, plasticizer: 8-20 parts, vulcanizing agent: 1-5 parts, accelerator: 2-7 parts; its manufacturing method includes: The following steps are: (1) first mixing, (2) rubber filtering, (3) second mixing. The reaction force plate material for the automotive electronic booster provided by the invention has high mixing uniformity and stable performance, and at the same time avoids the risk of scorch, realizes high temperature and short-time vulcanization of the product, avoids delamination, and improves production efficiency and product quality. |
