Portable polyurethane emergency curing device

The utility model relates to a portable polyurethane emergency curing device. The two curing agents can be sprayed at the same time and cured rapidly, leaked dangerous objects are wrapped in a sealed mode, pollutants are isolated from air, the two curing agents can be contained in the urethane bottle A and the polyurethane bottle B respectively, the two curing agents can be sprayed out at the same time at a high speed under boosting of high-pressure gas, and meanwhile the two curing agents can be sprayed out at a high speed. Under the cooperation of a spraying button, a closing button, a polyurethane A electric control valve, a polyurethane A liquid pump, a polyurethane B electric control valve, a polyurethane B liquid pump, a gas electric control valve, a gas pump and a controller, one-key starting and one-key closing are achieved, meanwhile, after closing, self-cleaning of the spray head can be achieved, and blockage of the spray head in the follow-up using process is avoided. 本实用新型涉及一种便携式聚氨酯应急固化装置；可以实现两种固化
