Abstract

The invention relates to a high-temperature-resistant spraying quick-setting rubber asphalt waterproof coating, which is prepared from modified emulsified asphalt and high molecular polymer rubber latex. The liquid rubber asphalt emulsion component is added with vulcanizing agent and composite reinforcing agent, and then combined with The coagulant components are mixed and prepared in proportion to the high temperature resistant water-based spray coating. The invention is a new type of spraying quick-setting rubber asphalt environmental protection waterproof material. The coating is non-toxic, tasteless and does not pollute the environment. Elongation (>1000%), high elastic recovery rate (>90%), high bond strength (>0.5MPa), excellent low temperature resistance (-30 ℃ no fracture), excellent aging resistance, acid and alkali resistance Performance, cohesion and shear resistance to prevent structural damage caused by water seepage and extend the life of highway bridges.

Description

technical field [0001] The invention relates to a waterproof paint, in particular to a high-temperature-resistant spray-coated quick-setting rubber asphalt waterproof paint. technical background [0002] In recent years, my country's road construction has developed rapidly, the road grade has been continuously improved, and the proportion of bridge structures is increasing. Because most of the bridge decks in the past did not lay a waterproof layer, the road bridges were damaged and cracked, which affected the service life of the road bridges. Therefore, doing a good job of waterproofing the road and bridge is the guarantee to ensure the quality of the road. With the development of road and bridge waterproof technology, my country promulgated industry standards for road and bridge waterproof materials, providing technical support for the quality of road and bridge projects. Contents of the invention [0003] In order to meet the needs of the road and bridge waterproof ma...
