Abstract

The invention discloses a pipeline emergency plugging agent which is composed of the following components in percentage by weight: 45-50% of epoxy resin, 2-5% of toughener, 0-2% of nano material, 3-20% of diluter, 0-5% of coupling agent, 25-80% of filler, 5-40% of curing agent and 0-4% of accelerator. The pipeline emergency plugging agent satisfies the pipeline plugging adhesive requirements in the aspects of heat resistance and shear strength, has the advantages of high setting and hardening speed, high bonding capacity and favorable dielectric resistance, and is convenient for construction and operation. The pipeline emergency plugging agent can be cured at room temperature at high speed, and thus, can simplify the operation. The technique is simple, and thus, is especially suitable for field pipeline plugging operation.

Description

technical field [0001] The invention relates to a pipeline emergency plugging material, which belongs to new chemical materials or polymer materials. Background technique [0002] Once the pipeline leaks, in addition to the direct economic loss caused by the loss of the medium, it may also cause environmental pollution, hidden safety hazards and other negative social impacts. At present, due to a series of advantages such as fast curing, high strength, good durability, stable storage, and a wide range of bonding materials, room temperature fast-curing epoxy adhesives have been widely used in aerospace, automobiles, ships, machinery manufacturing, electronics and other industries as well as in daily life. Widely used, it is an urgently needed and irreplaceable chemical material in China. Foreign countries have been developing since the early 1970s, and there were nearly a hundred varieties in the mid-1990s, of which 5min curing varieties accounted for the majority. The main...
