Abstract

The invention discloses a preparation method of a multifunctional rubber synthesized based on nitrile rubber, which is made of the following raw materials in parts by mass: nitrile rubber 25-40, chlorohydrin rubber 60-70, modified chloroprene rubber 20‑50, carbon black 10‑20, decabromodiphenylethane 4‑5, magnesium oxide 12‑18, vulcanizing agent 1‑1.5, stearic acid 4‑6, zinc oxide 5‑8, antioxidant 7‑10 , flame retardant 8‑15, 2‑dihydroquinoline polymer 1‑2. It can be made of temperature and cold resistance through a simple preparation method. Not only the cost of rubber is low, the effect of chemical corrosion resistance is good, but also the preparation process is simple, easy to industrialize, and it has excellent flame retardancy, stability, heat resistance, and no rubber. It is non-toxic and environmentally friendly, can effectively reduce environmental pollution, and has a long service life.

Description

technical field [0001] The invention relates to the field of rubber, in particular to a method for preparing multifunctional rubber synthesized based on nitrile rubber. Background technique [0002] Rubber Highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer, its glass transition temperature (Tg) is low, and its molecular weight is often large, greater than hundreds of thousands. Rubber is a highly elastic polymer, its molecular structure is chain, and the molecular chain has high flexibility. The molecular chain of rubber can be cross-linked (vulcanized), and the cross-linked material has the ability to recover quickly when it is deformed by an external force, and has good physical and mechanical properties and chemical stability. Only through cross-linking...
