Ship launching fiber-reinforced rubber air bag and molding technique thereof

Abstract

The invention belongs to the field of ship launching and discloses a ship launching fiber-reinforced rubber air bag and a molding technique thereof. The ship launching fiber-reinforced rubber air bag is characterized in that bag heads at the two ends of a core mold are of an isostress structure, and a rubber air bag body is provided with a rubber layer, a fiber-reinforced layer and a protection layer. The molding technique includes the steps that firstly, a rubber band is wound around the core mold to cover the surface of the core mold, so that the rubber layer is formed; dry fiber yarns cover the surface of the rubber layer through a specific geodesic line winding technology, so that the fiber-reinforced layer is formed; then the surface of the fiber-reinforced layer is wound with multiple layers of rubber bands, so that the protection layer is formed; and finally the rubber air bag obtained through winding is subjected to sulfuration and demolding. By means of the technique, automatic machining of one machine can be achieved, the machining environment is optimal, the labor intensity is low, and the production efficiency is high. The ship launching fiber-reinforced rubber air bag is good in flexibility, low in mass, low in cost, long in service life, stable in reinforced structure, capable of being recycled, and capable of bearing high-tonnage ship launching.

Description

technical field [0001] The invention relates to the field of ship launching, in particular to a molding process of fiber reinforced rubber airbags for ship launching. Background technique [0002] The ship launching airbag is the first ship launching technology in my country. The current ship launching airbag is a complex multi-layer flexible laminated structure composed of rubber as the basic material and reinforcing fibers. With the development of ship technology and the continuous increase of hull tonnage, higher quality requirements are put forward for launching airbags. However, the current rubber airbag molding technology mainly adopts multi-layer rubber structure, and most of them are formed by manually laying multi-layer cord fabrics and then vulcanized. The production environment is harsh, the labor intensity is high, the production efficiency is low, and the quality of the molded products is poor. Low, uneven force, unstable structure.
