Chloroprene rubber/nature rubber for skirt of hovercraft and manufacturing method of chloroprene rubber/nature rubber

Abstract

The invention relates to a chloroprene rubber / nature rubber for skirt of a hovercraft and a manufacturing method of chloroprene rubber / nature rubber; banburying, open milling and vulcanization technology are carried out on NR (natural rubber), CR (chloroprene rubber), S (sulfur), DM (dry matters), ZnO (zinc oxide), MgO (magnesium oxide), NA-22, carbon black N550 and N330, kaolin, white carbon black, Si-69, rubber adhesive XS-110, StA, aromatic oil, preservation wax, anti-aging agents 4010NA, A and RD; and in the rubber adhesive XS-110, rubber adhesive XS-110 and resorcinol pre-condensation resin are used as main body materials, active additives and inert fillers are added for manufacturing, and then the rubber adhesive XS-110 is directly added in the later stage of mixing of sizing materials, material feeding speed is high, so that the process is simple and easy; and white carbon black / si-69, namely rubber containing an XS-100 / white carbon black / si-69 system, is matched, so that the adhesive intensity of the rubber and a framework material is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of rubber formulations, in particular to neoprene / natural rubber for hovercraft aprons and a production method. Background technique [0002] Hovercraft use harsh conditions, and the life of its apron is always the main factor affecting the use of the hovercraft. The hovercraft apron is violently beaten and flexed repeatedly by wind waves and air currents, resulting in delamination between the rubber and the skeleton material, which will accelerate the damage of the apron. In short, the low bond strength of the hovercraft apron rubber to the frame material is the cause of this phenomenon. Contents of the invention [0003] Aiming at the deficiencies in the existing rubber formula technology, the purpose of the present invention is to solve the delamination phenomenon between the rubber of the hovercraft apron and the skeleton material, provide a neoprene / natural rubber for the hovercraft apron and a manuf...
