Embodiment 1

[0037] A method for preparing a rubber compound for leakage plugging, the method comprising the following process steps:

[0038] (1) Put 15kg of fluorocarbon resin, 10kg of foaming agent fatty alcohol polyoxyethylene ether sodium sulfate, 15kg of temperature-resistant filler clay and alumina, and 5kg of colorant colloidal graphite into the disperser to fully disperse until the color is uniform ;

[0039] (2) Add 15kg of lubricating oil glyceryl stearate, and 20kg of asbestos fibers continue to disperse for 20min to obtain a uniformly mixed material;

[0040] (3) Put the uniformly mixed material into the feeding barrel of the extruder. The temperature of the feeding barrel is controlled at 100°C. Start the extruder to extrude the rubber material into a rod shape. After the rod rubber material cools to room temperature, cut it according to the specifications. Just pack it.

Embodiment 2

[0042] A method for preparing the above-mentioned rubber compound, the method comprises the following processing steps:

[0043] (1) Put 10kg of natural rubber, 10kg of acrylic resin, 12.5kg of foaming agent sodium bicarbonate, 10kg of heat-resistant filler sodium silicate, 10kg of magnesium silicate, 20kg of aluminum hydroxide, and 7.5kg of colorant iron oxide red into the dispersion Fully disperse in the machine until the color is uniform;

[0044] (2) Add 30kg of lubricating oil fatty acid glyceride, 35kg of glass fibers continue to disperse evenly, and then pass through the roller machine three times to form a block to obtain a uniformly mixed material;

[0045] (3) Put the uniformly mixed material into the feeding barrel of the extruder. The temperature of the feeding barrel is controlled at 90°C. Start the extruder to extrude the rubber into a rod. After the rod is cooled to room temperature, cut it according to the specification and pack it. That's it.

Embodiment 3

[0047] A preparation method of sizing material for plugging, characterized in that the method comprises the following steps:

[0048] 1) Put 10kg of silicone resin, 8kg of furan resin, 7kg of sodium α-olefin sulfonate and 8kg of azobisisobutyronitrile as foaming agent, 50kg of kaolin as temperature-resistant filler and 10kg of colorant titanium dioxide into the disperser Stir and disperse until the mixture is uniform in color;

[0049] 2) Add 10kg of dioctyl adipate and 10kg of epoxidized soybean oil to the mixture as lubricating oil ester and 30kg of glass fiber, and continue to stir and disperse for 30 minutes to obtain a uniformly mixed material;

[0050] 3) Put the uniformly mixed material into the feeding barrel of the extruder, control the temperature of the feeding barrel to 110°C, then start the extruder, extrude the uniformly mixed material into a rod, and cut the rod after cooling to room temperature .

Abstract

The invention relates to a leak-blocking adhesive and a preparation method thereof. The adhesive consists of the following components in part by weight: 15 to 25 parts of synthetic resin, 15 to 30 parts of lubricating grease, 10 to 15 parts of foaming agent, 20 to 35 parts of fibrous filler, 30 to 50 parts of heat-resistant filler and 5 to 10 parts of coloring agent; the synthetic resin, the foaming agent, the heat-resistant filler and the coloring agent are uniformly dispersed and then are added with the lubricating grease and the fibrous filler, the uniformly mixed materials are added into an extruder and are extruded to form a stick shape, and after being cooled to the room temperature, the stick-shaped adhesive is cut. Compared with the prior art, the leak-blocking adhesive can tolerate most of chemical media, is highly universal, can be automatically filled into a neighboring gap when being heated, enhances the leak-blocking effect, prevents the phenomena of adhesive leakage and adhesive spouting, has excellent flowing property before being solidified, is convenient and easy to operate, and has a wide resisted temperature range.

Description

technical field [0001] The invention relates to a bonding rubber material and a preparation method thereof, in particular to a sealing rubber material and a preparation method thereof. Background technique [0002] The plugging compound is usually called a plugging glue stick, which is generally used for non-stop and pressure plugging of chemical pipelines. Modern large-scale chemical plants use a large number of pipelines to transport chemical materials, and the pipelines are connected by various flanges, and most of the leakage of pipelines occurs at the flanges of the connections. The application method of the plugging glue stick is to inject the plugging glue stick into the leakage of the flange through a special tool under the working condition with a certain pressure or temperature to achieve the plugging effect. There are generally two kinds of glue sticks for plugging, one is thermosetting rubber glue sticks, which can withstand relatively high temperatures, but rub...
