AI Technical Summary

Problems solved by technology

Epoxy asphalt has high strength, which is generally three to four times that of ordinary asphalt. However, epoxy asphalt has a long curing period and high cost. It must be completed within one hour from production to construction, otherwise it can only be discarded. The impact on the construction environment Temperature and humidity also have certain requirements

Abstract

The invention belongs to the field of building materials, and provides a foamed epoxy asphalt material. The foamed epoxy asphalt material comprises the following raw materials in parts by weight: 30-40 parts of asphalt, 5-10 parts of epoxy resin, 5-10 parts of silicon dioxide, 5-10 parts of diacetone acrylamide, 1-3 parts of p-hydroxybenzenesulfonic acid, 1-3 parts of polyoxypropylene glycerol ether and 1-3 parts of stearic acid file. Advantages of high strength of common epoxy asphalt are reserved, meanwhile, the curing time is shortened, and construction efficiency is improved. The foamed epoxy asphalt material is uniform in foaming and stable in texture, and can be used at an environment temperature of 25-40 DEG C. The raw materials are simple and are easy to obtain, and preparation isconvenient.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a foamed epoxy asphalt material. Background technique [0002] Epoxy asphalt is a complex chemically modified mixture of epoxy resin, curing agent and base asphalt. It was only introduced to my country from the United States ten years ago, and it has been applied on bridges such as the Second Nanjing Yangtze River Bridge and the Runyang Yangtze River Highway Bridge with good results. Epoxy asphalt has high strength, which is generally three to four times that of ordinary asphalt. However, epoxy asphalt has a long curing period and high cost. It must be completed within one hour from production to construction, otherwise it can only be discarded. The impact on the construction environment Temperature and humidity also have certain requirements. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiency of common epoxy asp...
