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.
