Abstract

The invention relates to a high-temperature resistant spray fast-setting rubber asphalt waterproof coating which is a high-temperature resistant water-based spray coating prepared proportionally by adding a vulcanizing agent and a composite reinforcing agent into liquid rubber asphalt mastic emulsion prepared from modified emulsified asphalt and high-molecular polymer rubber latex and then mixing with a coagulating agent. The high-temperature resistant spray fast-setting rubber asphalt waterproof coating provided by the invention is a novel spray fast-setting rubber asphalt environment-friendly waterproof material which is nontoxic, tasteless and pollution-free and can be subjected to cold construction at normal temperature; and meanwhile, the high-temperature resistant spray fast-setting rubber asphalt waterproof coating has good heat resistance (160 DEG C), high elongation at break (greater than 1,000%), high elasticity recovery rate (greater than 90%), high bonding strength (greater than 0.5MPa), excellent low temperature resistance (without breakage at -30 DEG C) and excellent ageing resistance, acid/alkali resistance, cohesiveness and shear resistance, and can prevent structural damage caused by water penetration so as to prolong the service 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...
