Problems solved by technology

In addition, although some domestic units have developed some metal fillers and wear-resistant adhesives, their performance cannot meet the requirements for equipment maintenance.
Although the performance of the above-mentioned foreign-developed repair materials is higher than that of domestic products, Germany’s Diamant products were used for tank track hangers in my country in the 1980s, but the strength and temperature resistance are still difficult to meet the demanding performance requirements for repairing military equipment or strength. equipment requirements, and the price of imported repair agents is extremely expensive, consuming a large amount of foreign exchange, resulting in the company's consumption of huge funds in equipment maintenance

Abstract

The invention provides a quick mending agent and a preparation method thereof. The mending agent is a normal-temperature curing dual-component reactive mending agent, and has better comprehensive performances than those of epoxy, anaerobic and other common adhesives; a cured adhesive layer is grey and has the bonding strength of 43MPa; and the temperature for using the mending agent is between 60and 180 DEG C. The quick mending agent is mainly used for sealing and blocking oil tanks, water tanks and gas transmission pipelines.

Description

technical field [0001] The invention relates to a fast repairing agent, in particular to an epoxy-modified normal-temperature curing two-component reactive fast adhesive. Background technique [0002] As an important means of maintenance, surface engineering has been paid more and more attention. As an important part of the surface engineering discipline n9 surface technology, surface repair technology includes electroplating, electro-brush plating, thermal spraying, adhesive bonding, etc. These repair methods complement each other and become the necessary emergency measures for equipment maintenance. The old parts have been brought back to life, saving huge economic losses for the enterprise, and equipment maintenance has become an integral part of productivity. [0003] As one of the modern surface technologies, surface adhesive coating technology has played an important role in the field of equipment maintenance in recent years and achieved good social and huge economic ...
