Description

The manufacture method of high-strength marine air bag shaped by lapping

The present invention relates to the manufacturing process of air sac container.

At present, domesticly manyly repair, the shipbuilding yard in, the upper and lower water conservancy project skill of craft adopted boats and ships air bag water conservancy project skill up and down, as using hoisting air chamber jacking boats and ships, so that beat pier or tear pier open, the use scroll airbag moves the upper and lower water of boats and ships etc.As for the manufacturing process of air-bag for ship, the inner tube of a tyre formula air bag with high intensity of introducing in the existing disclosed CN85203958 of the having patent, its method is that natural fiber or chemical fiber are twined and be bonded on the inner tube of a tyre, the inner tube of a tyre is one or more layers, the offset plate or the rubber of sulfuration.Other has the CN87101374 patent application to disclose to heat after vinylon cord that a kind of employing presses rubber twines the manufacture method of the air-bag for ship that press cure forms, and this method also is to process on the inner tube of a tyre.Through long-time production practice and use proof, preceding a kind of air bag has stopped producing and using because working strength is not enough, fragile; A kind of production method in back, though adopted the offset plate of the higher band cord of intensity, owing to be Wrapping formed on the inner tube of a tyre, the one, it is big to manufacture difficulty, and bladder shape is difficult to well-balanced, and technology is difficult to grasp, and the 2nd, owing to the utricule unshapeliness, influence the result of use of air bag.

The manufacturing process that the purpose of this invention is to provide the high-strength air-bag for ship of a kind of inner tube free of practical and type tire.

This utricule that is overlapped to form finger formula high-strength air-bag for ship is that the rubber buttress that adopts multilayer to have continuous synthetic fibre cord (or cord of other syntheticfibres, natural fiber, metal filament etc.) carries out cutting according to the air bag size, and will cut out good rubber buttress according to its cord trend, stagger and pile up together after the lapped seam, the overlap joint of reeling then, and carry out every layer of rubber plate and lap-joint bonding with adhesives, it is bonded as one, last, with the utricule made through high temperature vulcanized and moulding.

This air bag with high intensity has adopted shaped by lapping, is bonded as the technology of one again, and making is got up more feasible, easy, and utricule is more well-balanced, firm, has saved the inconvenience of making the inner tube of a tyre and twining on the type tire, has improved product design and has made work efficiency.As the rolling air-bag for ship of being with the rubber coiled sheet of vinylon cords around shaped by lapping with 3 layers, proof is functional in using practice, and it allows working pressure greater than 2 kilograms per centimeter ², air-tightness is good, has prolonged service life.And can adopt different number of plies rubber plates to process according to customer requirement, breakage occurs and also can adopt the overlap joint bonding mode to repair.

Description of drawings.

Fig. 1, Fig. 2 are the part sectional view of roller air-bag for ship of the present invention, and wherein (1) is the capsule body; (2) be the capsule head; (3) be Nang Zui.

Fig. 3 is Figure 1A-A place section-drawing, and wherein (4) are the nexine offset plate; (5) be the middle level offset plate; (6) be outer offset plate.

Fig. 4 is three layers of rubber plate before the overlap joint of reeling piles up scheme drawing, wherein (7) for overlap joint with stitching.

Below in conjunction with embodiment and accompanying drawing the present invention is elaborated.

Present embodiment is around overlap joint and the high-strength marine scroll airbag of moulding with three layers of rubber coiled sheet with continuous synthetic fibre cord.Being with every pulling force of continuous synthetic fibre cord fabric thread is 22 kilograms, and the rubber plate adopts No. 101 rubber of standard, and adhesives adopts gasoline.The size of three layers of rubber plate and disposing way thereof are: the inside one deck rubber board placing is below for utricule, its disposing way is parallel with utricule according to cord-thread direction, its length equals the length of capsule body and two capsule heads, and its width is spliced into the girth that equals the capsule body with the rubber plate; Interlayer rubber plate piles up on nexine rubber plate, it is vertical with the cord of nexine offset plate according to the cord trend that it piles up mode, its length is longer than 30 centimetres of capsule body girths, grow part and give over to overlap joint usefulness, its width is spliced into the rubber plate and equals capsule height degree, reserve the overlap joint seam when piling up topmost, and two-layer rubber plate is bonded together with gasoline; Outer rubber plate piles up on the rubber plate of middle level, and its cord trend and size are identical with middle level rubber plate when piling up, and just move downwards its top again when piling up, and reserves overlap joint with seam, also with gasoline skin and middle level rubber plate is bonded together.Then, three layers of offset plate that are bonded into one are awarded certain pressure, as using the compacting of iron alkali.At last, three layers of rubber plate of compacting are reeled inwards, each layer overlaps with seam with the overlap joint of reserving respectively and is bonding with gasoline, makes tubular capsule body like this.Two acrocyst heads are coniform, use coniform mould during making, for put, the delivery tool is convenient, a part was not bonding in the middle of capsule can be reserved when last overlap joint is bonding, capsule head innermost layer is by nexine rubber plate two ends it to be cut into strip to be layered on the mould, carry out fissure of displacement overlap joint with the trapezoidal rubber plate that is cut into above it, bonding with gasoline, be bonded in capsule head and capsule body seam with the offset plate bar then, gain in strength, use the trapezoidal rubber plate of one deck fissure of displacement bonding above again, this two-layer trapezoidal rubber plate cord trend is vertical with undermost offset plate bar.After making two capsule heads, capsule head mould tool is taken out from the centre joint, with gasoline that the capsule body centre joint is bonding again, and with whole airbag aeration.The inflation back is twined a circle and bonding at capsule head and capsule body junction with kiss-coating cord line adhesive lath, the outside again with broad not with the thick 5 millimeters 101 rubber laths winding adhesive seal of cord, simultaneously, the longitudinal seam place of capsule body also uses this rubber lath adhesive seal.For improving the air bag working strength, the rubber plate of capsule body and capsule head outermost layer band cord uses thickening rubber plate, thick 2mm.All outermost layer seams of capsule body and capsule head all with thick 5mm not with the rubber lath adhesive seal of cord.After whole air bag is made, utricule is put into direct vulcanizing tank vulcanize, in 4 kilograms per centimeter ²Down sulfuration 50～90 minutes of pressure.
