NOVELTY - A damping pad comprises 70-90 pts. wt. natural rubber, 20-30 pts. wt. nitrile rubber, 5-10 pts. wt. anti-aging agent, 4-6 pts. wt. vulcanizing agent, 1-2 pts. wt. accelerant, 3-5 pts. wt. plasticizer, 20-30 pts. wt. reinforcing agent and 1-2 pts. wt. anti-scorch agent. The anti-aging agent comprises nano zinc oxide, nano titanium dioxide and rare earth compound at weight ratio fo 1-2: 2-5: 2-4. USE - Damping pad used for compressor and refrigerator for polymer material field. ADVANTAGE - The damping pad has good anti-aging and anti-cracking effects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of damping pad comprising weighing natural rubber, nitrile rubber, anti-aging agent, accelerant, vulcanizing agent, plasticizer, reinforcing agent and anti-scorch agent, mixing natural rubber, nitrile rubber, anti-aging agent, accelerant, plasticizer, reinforcing agent and anti-scorch agent, rolling, thinning, repeating for 3-5 times to obtain mixed rubber, tableting mixed rubber, cooling to obtain film, mixing film and vulcanizing agent, heating to melt film, vulcanizing for 1-2 hours to obtain vulcanized rubber material, performing wire drawing forming to vulcanized rubber material at staggered and alternate wire drawing direction, and trimming.
