Abstract

The invention discloses a natural / butadiene rubber formula for a hovership finger and a manufacturing method thereof. The manufacturing method comprises the following step of: carrying out banburying, opening, batching-off and vulcanizing on NR (Natural Rubber), BR (Butadiene Rubber), S, DM, NOBS (N-(Oxidiethylene)-2-benzothiazolyl sulfonamide), ZnO, carbon black N550, carbon black N330, argil, white carbon black, Si-69, a rubber cement XS-100, StA, aromatic oil, protection wax, anti-aging agent 4010NA, anti-aging agent A and RD. The BR is used in the NR, the compound cement XS-100 with good dispersing property is adopted and is high in feeding; and the manufacturing method is simple and easy to operate; and a less quantity of BR is adopted in the NR, so that the abrasive resistance is improved; and the white carbon black and si-69 are matched for use, so that the bonding strength of rubber and a framework material can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of rubber, in particular to a formula of natural / butadiene rubber for hovercraft fingers and a production method thereof. Background technique [0002] Hovercraft use harsh conditions, and its replaceable parts—fingers are always one of the main factors affecting the service life of the hovercraft. The hovercraft is violently beaten and repeatedly flexed by wind waves and air currents, which causes the rubber layer of the finger to wear, accelerates the tearing and delamination between the rubber layer and the skeleton material, and leads to rapid failure of the finger. In short, the abrasion resistance of the rubber of the hovercraft fingers, and the low bond strength properties of the rubber and the frame material are the reasons for this phenomenon. Contents of the invention [0003] Aiming at the deficiencies in the existing rubber technology, the purpose of the present invention is to solve the wear...
