Novel threaded joint sealing material

Abstract

The invention is applicable to the technical field of sealing materials for threaded joints of pipes, and provides a novel threaded joint sealing material. The novel threaded joint sealing material comprises a coating layer material and a coated layer material which are compounded with each other, wherein the coating layer material comprises the following components in parts by weight: 40-60 partsof sodium-based clay, 2-5 parts of a clay additive, 10-20 parts of epoxy resin, 5-10 parts of polyurethane, 5-10 parts of organic silicon, 5-8 parts of a vinyl-propylene elastomer, and 12-15 parts ofpolytetrafluoroethylene, wherein the sodium-based clay enables the coating layer material to have the characteristic of water swelling, so that secondary sealing can be carried out, and then the sealing effect is better, the epoxy resin, polyurethane, organic silicon, vinyl-propylene elastomer and polytetrafluoroethylene which are used as ingredients are added into the coating layer material, sothat the coating layer material is better in elasticity and higher in viscosity, the coated layer material is made of non-woven fabric, thus the sealing material has more stable overall structural strength and higher tearing resistance, and then the service life is longer.

Description

technical field [0001] The invention belongs to the technical field of sealing materials for thread joints of pipe materials, and in particular relates to a novel sealing material for thread joints. Background technique [0002] Pipe is a commonly used fluid transmission tool in construction. The connection between pipes is generally in the form of wire connection. Wire connection is also called threaded connection. It is a connection used in water supply, heating, oil circuit, compressed air, etc. The method is to connect two pipe fittings of different or the same material, the inner and outer wires of the car, and rotate them. The wire joints between the pipes need to be further sealed with sealing materials. [0003] At present, the sealing materials that should be available on the market include: hemp silk, white thick paint, raw material tape, anaerobic adhesive, etc. Hemp silk is a plant rhizome, which has been used for the longest time and is the oldest sealing mater...

AI Technical Summary

Problems solved by technology

Its technical defect is that the operation is cumbersome and the use of technical requirements is very high

It is very labor-intensive. White thick lacquer is used as an auxiliary product for sealing materials. It cannot achieve the sealing effect when used alone, and there are certain toxic and harmful substances. It is not easy to clean. Raw material tape is a common sealing material in the market at present, and the pressure bearing performance of raw material tape is average. , It is very time-consuming to use. It takes 15-20 turns to wind a threaded button. At the same time, the cost of materials is also the highest, which is time-consuming and labor-intensive.

Anaerobic adhesive is a new type of sealing material in the market this year. It has good sealing performance, but it needs to wait for more than 24 hours before it can be pressed after use. It is more convenient to install, and it is very difficult to remove and modify. It is easy to install and not easy to disassemble.

At the same time, there should be no oil stains on the wire connection pipe, and it needs to be wiped clean before use, otherwise the glue and oil will not react, and the sealing effect will not be achieved
