Abstract

The invention belongs to the field of casting materials, and in particular relates to an oxygen-releasing quick curing patching material as well as a preparation method and application of the material in the field of quickly repairing pavements. The oxygen-releasing quick curing patching material provided by the invention consists of 60-95 parts of compact aggregate, 4-30 parts of thermoplastic resin bonder and1-10 parts of a thermal initiation latent curing agent which can induce the thermoplastic resin bonder to be quickly cured in a heated state, and 0.5-1 part of solid oxidant which is heated to release oxygen. The patching material in the heated state can release a small amount of oxygen and support combustion of heat release of combusting substances so as to provide heat required by curing the patching material, and therefore, the purposes of quick curing and repairing are realized.

Description

technical field [0001] The invention belongs to the field of foundry materials, and in particular relates to a repairing material that can be heated to release oxygen and can be rapidly cured, a preparation method thereof, and an application in the field of rapid repair of road surfaces. Background technique [0002] With the rapid development of my country's economy, the number of airport runways has increased rapidly, a large number of high-grade expressways have been constructed, and the implementation of concrete projects such as urban squares and municipal roads has improved the quality of human life and promoted the healthy development of the national economy. Most of the existing roads use concrete to construct the pavement, which not only has good quality but also has a long service life. However, the maintenance of concrete pavement after the road surface is damaged during use is more complicated. It needs to be closed and stopped for repair. It requires the use of ...
