Problems solved by technology

[0004] In order to overcome the disadvantages existing in the prior art that marine airbag materials are combined with joints, are not tight, are not uniformly vulcanized, are unevenly stressed on the skeleton, are prone to air leakage, and have low pressure in blasting, etc., the present invention provides a high-strength airbag and Its production process, the airbag is formed by sticking and vulcanized as a whole, without a single seam all over the body, which greatly increases the elasticity of the airbag, improves the strength of anti-burst and the number of times of impact fatigue resistance, and has a long service life

Embodiment 1

[0017] Embodiment 1 The high-strength airbag described in the present invention is composed of an airbag body 1, an airbag head 2, and an airbag valve 3. The airbag body 1 is composed of an inner sleeve layer and several layers of hanging glue that are cross-applied from the inside to the outside. The cord fabric is formed, and the airbag head 2 is connected together with the airbag body 1 into a conical shape, and the airbag valve 3 for inflation is fixedly installed on the airbag head.

[0018] The direction of the glued cord fabric of the airbag body 1 is arranged parallel to the longitudinal fabric bars from one end of the bag head to the other end, and the two sides are glued and rolled into a barrel shape as the inner sleeve, and then the inner sleeve is circled from the inside to the outside to apply two Layers of rubber cord fabric, the angle of application between the two layers of cord fabric intersects, and the direction of the cross application of the outer layer of...

Embodiment 2

[0022] Embodiment 2 The high-strength airbag of the present invention is composed of an airbag body 1, an airbag head 2, and an airbag valve 3. The airbag body 1 is composed of an inner jacket layer and several layers of hanging glue that are cross-applied from the inside to the outside. The cord fabric is formed, and the airbag head 2 is connected together with the airbag body 1 into a conical shape, and the airbag valve 3 for inflation is fixedly installed on the airbag head.

[0023] The direction of the glued cord fabric of the airbag body 1 is arranged parallel to the longitudinal fabric bars from one end of the bag head to the other end, and the two sides are glued and rolled into a barrel shape as the inner sleeve, and then the inner sleeve is circled from the inside to the outside to apply two Layers of rubber cord fabric, the angle of application between the two layers of cord fabric intersects, and the direction of the cross application of the outer layer of cord fabr...

Abstract

The invention is a high-intension gas cell and its facture. The gas cell comprises the cell body, the cell head and the air gate mouth. The cell body is composed of the inner sleeving layer and plural layers of curtain cloth. The cell head and the cell body are jointed together to form the conoid shape, the cell head is solidified with the air gate mouth. The facture is to longitudinal arrange the curtain cloth, adhere the two sides and roll them to barrel shape to be the inner sleeve. The demolishing inner pressure of the gas cell is higher than 1.11 MPa, and the cell wall is sealed well. The invention has a wide range of appliance.

Description

Technical field [0001] The invention relates to a high-strength air bag and a production process thereof, in particular to an air bag used for the upper discharge and launching of ships and the production process thereof. Background technique [0002] Airbag launching technology for ships first appeared in the early 1980s. Due to the low carrying capacity of airbags at that time, they could only be applied to small wide-bottomed barges with a self-weight of tens of tons, and it was difficult to break through the threshold of launching weight exceeding 500 tons. In order to meet the needs of the safe launch of larger ships, the strength of the airbag itself must be improved. The material selection, bladder structure, manufacturing method and process flow are the key factors that determine whether the strength of the airbag can be improved. [0003] At present, the manufacturing process of marine airbags mainly has the following methods. One is to use the method of overlappin...
