Problems solved by technology

It can be found from the relevant literature that the repair of pipelines is mainly plugging and repairing. The problem is that the operation is limited, especially for the leaks on the pipe wall. Corrosion is more serious when it grows; the steel skin is covered, which increases the load bearing of the pipeline, and it is difficult to process, and the appearance of the pipeline is not beautiful after the above operations

Abstract

The invention provides a chemical pipeline adhesive which comprises the following components in parts by weight: 50-80 parts of modified epoxy resin, 12-18 parts of a coupling agent, 16-20 parts of a thixotropic agent, 20-60 parts of a nano chemical-resistant powder, and 13-20 parts of an anti-aging agent, and 10-15 parts of a color paste, wherein the nano chemical-resistant powder includes one or more of nano calcium carbonate, nano alumina, nano talcum powder, nano titanium dioxide, nano silica, a nano metal powder, nano zinc oxide, nano magnesium oxide or nano zirconium oxide. The chemical pipeline adhesive has the beneficial effects that (1) the modified epoxy resin is a nitrile rubber-polyurethane-epoxy resin ternary copolymer compound, and is combined with common advantages of both CTBN modified epoxy resin and polyurethane modified epoxy resin, so that the adhesive ability of the adhesive is increased, and the tensile strength and impact resistance are also greatly improved.

Description

technical field [0001] The invention relates to a chemical pipeline adhesive. Background technique [0002] In metallurgy and chemical production, pipelines play the role of transporting fluid and gas medium. Due to the corrosion of the medium or the atmosphere, chemical pipelines often leak, which causes material leakage and brings unsafe factors to production. The discharge of some harmful media also causes environmental pollution. Temporary plugging and repairing can only solve individual problems. For severely aging pipelines, the frequent leakage problem is no longer a problem that can be solved by plugging. If all the pipelines are replaced, the impact on production will be immeasurable. [0003] The special repair agent for chemical pipelines is a kind of coating on the surface of chemical pipelines. As a layer of organic composite material, it can not only be tightly bonded to the pipeline wall, but also a layer of functional polymer material with special chemical r...
