Problems solved by technology

However, due to the low tensile strength of the asbestos-free fiber material itself, when the internal pressure of the used part is high, leakage is likely to occur. How to make up for the shortcomings of the asbestos-free material itself and better apply it to the sealing industry has become a must. critical issue
Manually apply the adhesive on the surface of the gasket, which not only requires a large labor force, but also has low work efficiency, and wastes materials and increases production costs.

Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment: see figure 1 with figure 2 , a full-circumferential sealing gasket, including a body 1, the body 1 is made of pressed non-asbestos material, and can also be made of other composite materials. In this embodiment, non-asbestos material is used. The thickness of the main body 1 is 0.5mm-1.0mm.

[0013] The edge of the inner hole 2 of the main body 1 is uniformly coated with adhesive glue on the edge of the inner hole 2 of the main body 1 by means of rotary dipping, and then the adhesive layer 3 is formed by baking at a drying temperature and gasket separation technology. The glue layer 3 is firmly bonded to the edge of the inner hole 2 of the body 1, so that the body 1 and the glue layer 3 are tightly bonded together. The glue coated on the edge of the inner hole 2 can be silica gel, fluorine rubber, nitrile rubber, etc., preferably silica ge...

Abstract

The invention relates to the field of gaskets, in particular to a circumferential sealing gasket and a production process thereof. The circumferential sealing gasket comprises a body. Bonding glue is coated at the position of an inner hole of the body evenly to form a glue layer. The circumferential sealing gasket has the advantages of being oil-resistant, pressure-resistant, low in leaking rate, good in sealing performance, good in compensation performance, good in machinability, low in cost and the like. The glue layer is first in contact with the upper face and the lower face of a flange, face pressure between flanges can be increased, the strength of the gasket itself can be improved by coating silica gel on the inner hole of the gasket, and the inner hole is prevented from leaking. An advanced mature manufacturing technology can be adopted in the process to achieve batch production, labor force is reduced, and working efficiency is improved. Consumed bonding agent is reduced, and cost is saved.

Description

technical field [0001] The invention relates to the field of gaskets, in particular to a full-circumference sealing gasket and a production process thereof. Background technique [0002] Gasket is an indispensable part of the sealing industry. Its main function is to prevent the medium from leaking from the sealing mechanism. Due to the requirements of its working environment, gaskets are also divided into many types. Asbestos material and asbestos-free fiber material gaskets are mainly used for the sealing of carburetors and tank chambers. With the improvement of people's living standards and environmental protection awareness, asbestos materials have been gradually eliminated, and the application of non-asbestos fiber materials has become a trend. However, due to the low tensile strength of the asbestos-free fiber material itself, when the internal pressure of the used part is high, leakage is likely to occur. How to make up for the shortcomings of the asbestos-free mater...
