Problems solved by technology

However, due to the maintenance and welding of the car body, the deformation of the hatch cover and hatch structure caused by long-term vibration, the aging of the sealing ring, and the compression permanent deformation, the above two sealing methods cannot meet the long-term effective sealing of the armored vehicle power hatch.

Embodiment Construction

[0008] The manufacturing method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0009] 1. Overall vulcanization mold made by external agreement: process and manufacture the overall vulcanization mold according to the hatch cover and hatch size and sealing method.

[0010] 2. Preparation of the main rubber material: the natural rubber compound can be prepared by mixing according to the formula 5-6 of "Rubber Products Use Formula Encyclopedia".

[0011] 3. Preparation of the inner and outer rubber layer films for molding: the mixed rubber obtained in step 2 is rolled by a calender to obtain a raw film, and stored for later use.

[0012] 4. Preparation of the buffer reinforcement layer for molding (3) Coated fabric: Paste the mixed rubber obtained in step 2 on both sides of the domestic nylon knitted buffer cloth through a calender to prepare a raw rubber cloth for use.

[0013] 5. Preparation of external rubber profile...

Abstract

The invention discloses an inflation sealing tape for a power hatch of an armored vehicle. The inflation sealing tape belongs to a rubber hollow sealing product and is particularly used for the power hatch of the armored vehicle. The inflation sealing tape comprises an inner rubber layer, a buffer reinforced layer, an outer rubber layer, a rubber-attached rubber section, a hollow inflation cavity and an air valve; the sealing tape is preformed and embedded into a special mold, so as to be formed through integral inflation vulcanization technology. The inner rubber layer, the outer rubber layer, the rubber coated on both sides of the rubber-attached rubber section and the buffer reinforced layer are natural rubber mixed compound. The buffer reinforced layer is formed in a way that natural rubber mixed compound is rolled on both sides of chinlon knitted buffer fabric. The inflation sealing tape for the power hatch of the armored vehicle has the advantages that the deformation compensation is large, the aging resistance is good, the mildew resistant, salt mist resistant and damp and hot condition resistant performances are good, the service life is long, the sealing effect is good, and the performance is stable after the sealing tape is frequently compressed.

Description

technical field [0001] The invention belongs to a rubber hollow sealing product, in particular to a sealing tape for a power hatch of an armored vehicle. Background technique [0002] The armored vehicle power cabin is the power source of the whole vehicle, which is equipped with a high-power generator and a large number of circuits and oil circuit systems. If the seal fails, dust and impurities enter the engine circuit or oil circuit system, which will cause engine failure or mechanical damage, shorten the service life of the engine and the maintenance cycle of the whole vehicle. The traditional sealing method is to adopt two methods of contact sealing between the metal hatch cover and the hatch structure or embedding a solid rubber sealing ring between the hatch structure and the hatch cover. However, due to the maintenance and welding of the vehicle body, the deformation of the hatch cover and hatch structure caused by long-term vibration, the aging of the sealing ring,...
