Low dynamic multiplying power antifatigue neoprene material and preparation method thereof

Abstract

The invention discloses low dynamic multiplying power antifatigue neoprene material and a preparation method thereof. The low dynamic multiplying power antifatigue neoprene material is composed of the following raw materials by weight, neoprene 60-90 portions, trans-1,4-polyisoprene 10-40 portions, carbon black 10-80 portions, accelerant 2-6 portions, vulcanizing agent 4-10 portions, antiager 2-5 portions, active agent 6-10 portions and operating auxiliaries 2-10 portions. The low dynamic multiplying power antifatigue neoprene material has the advantages that the trans-1,4-polyisoprene (TPI) is adopted to be functional auxiliaries of rubber, an ordinary rubber processing device is adopted to process, rubber materials achieved are capable of being improved in the antifatigue and lowered in the dynamic multiplying power, and convenient and simple to process.

Description

technical field [0001] The invention relates to a neoprene material, in particular to a low dynamic ratio, fatigue-resistant neoprene material and a preparation method thereof. technical background [0002] A good shock-absorbing rubber material should have the following characteristics: 1) Excellent dynamic performance, with low dynamic magnification and high attenuation. Low dynamic magnification can provide high shock absorption performance for shock-absorbing products, while high attenuation It can provide products with high damping performance. 3) Fatigue damage resistance. Under the action of alternating stress or strain, the rubber material cannot complete the stress relaxation in time at the stress concentration area, and cracks will inevitably occur. A good shock-absorbing rubber material should have good The performance of inhibiting crack growth prolongs the service life of the product. 4) Environmental resistance. During the use of the product, environmental fa...

5) Bonding properties with metals, most of the shock-absorbing rubber products are composed of rubber materials and metal skeleton materials bonded together, so a good shock-absorbing rubber material should have good bonding properties with metal materials Otherwise, once the rubber material is separated from the metal frame, the function of the shock-absorbing product will be lost

However, the presence of chlorine atoms with a large steric hindrance restricts the molecular chain movement of neoprene, making the flexibility of the molecular chain of neoprene poor and the hysteresis loss large, which leads to shock absorption made of neoprene. The dynamic magnification of the product is very high, the shock absorption performance of the product is reduced, and the heat generation is large, which also leads to a shortened service life of the product

[0004] Due to these characteristics of neoprene, the use of neoprene as a shock-absorbing rubber material is greatly limited, and it is only used for shock-absorbing occasions.
