Problems solved by technology

But, there are following problems in the existing plugging glue with pressure: 1, the texture of the plugging glue with pressure is relatively soft, after it is put into the plugging tool with pressure, the glue with pressure will make the plugging gun The gun bolt sticks to the gun wall of the plugging gun, and there will be glue overflow between the plugging gun bolt and the gun wall, and the gun bolt cannot return
It is necessary to disassemble the gun body to return the gun bolt. The operation is cumbersome, time-consuming and labor-intensive, and it is easy to delay the plugging opportunity and bring losses to the enterprise; 2. The hardness of the plugging glue under pressure is poor, and it is easy to break; 3. The surface of the pressure plugging glue is rough and the appearance is not beautiful enough

Embodiment 1-10

[0010] The production process of pressure plugging glue is as follows:

[0011] (1) Take each raw material respectively according to the consumption in Table 1;

[0012] (2) Put the raw materials that have been weighed into the same container, and use a metal rod or a mixer for simple mixing. Then, put all the raw materials after the simple mixing on the open mill, and fully mix the raw materials. The uniform raw materials are put into the inlet of the extruder, and the cylindrical semi-finished products with different lengths and diameters of 21mm are extruded with the equal pressure of the extruder;

[0013] (3) Place the prepared semi-finished product on the board to lower the temperature of the product, and then cut the semi-finished product with different lengths into black cylindrical glue sticks with a diameter of 21mm and a length of 90mm according to the actual length. The product making process is over.

Abstract

The invention belongs to the field of leakage stopping adhesives, and especially relates to a pressure leakage-stopping adhesive. The pressure leakage-stopping adhesive comprises 5-20g of 107 adhesive, 0.2-1.2g of silicone oil, 1.5-9g of FB resin, 1.6-11.6g of montmorillonite, 1.6-11.6g of ferric oxide, 3.6-13.6g of titanium dioxide, 0.5-4.5g of white carbon black, 0.28-10.28g of mica powder, 0.32-2.32g of talcum powder, 0.5-3.5g of glass fiber, 0.2-1.2g of carbon fiber, 0.5-25g of liquid nitrile butadiene rubber, 0.3-2.3g of 108 adhesive, 0.2-1.2g of FR adhesive, 0.1-1.2g of stearic acid and 0-9g of glass ball. The inside of the pressure leakage-stopping adhesive is hard, so after the pressure leakage-stopping adhesive is put in a pressure leakage-stopping tool, the bolt of a leakage stopping gun does not adhere to the wall of the gun, no adhesive overflow appears at the leakage stopping gun bolt or the gun wall, and the gun bolt normally returns without disassembling the body of the gun; the pressure leakage-stopping adhesive has the advantages of use convenience, good hardness and beautiful appearance; and the pressure leakage-stopping adhesive cooperates with a cross-linking pressure leakage-stopping adhesive in the practical use process in order to realize a good leakage stopping effect.

Description

technical field [0001] The invention belongs to the field of leak-stopping glue, in particular to a leak-stopping glue under pressure. Background technique [0002] Pipeline container without fire and non-stop rapid plugging under pressure is referred to as plugging under pressure. The pressure plugging technology originated in the United Kingdom. It is an advanced equipment maintenance technology developed in the mid-1970s. It refers to leaks caused by corrosion or man-made leakage of various material pipeline containers and accessories with or without seals. And the plugging process of using one technology or a combination of multiple technologies in the pressure plugging. At present, the pressure plugging technology is widely used in ships, warships, petroleum, chemical industry, gas, power generation, metallurgy, papermaking, fire protection, storage and transportation, water supply, heating, wine making and other enterprises. It is an important means and can avoid the...
