Waterless urinal sealing liquid

The invention discloses a waterless urinal sealing liquid, which relates to a cleaning liquid and comprises the following components in percentage by weight: 80 to 98 percent of long-chain fatty amine, 0 to 20 percent of ester perfume, 0.3 to 2 percent of bactericide, and 0.01 to 0.02 percent of dye. The waterless urinal sealing liquid can prevent urine smell from dispersing into the air, has a high boiling point over 200 DEG C, a low freezing point lower than 20 DEG C below zero, can be used under various climatic conditions, and has a long service life; besides, the waterless urinal sealing liquid has a density of 0.8 to 0.9 g/cm smaller than that of urine and a viscosity similar to that of water, is insoluble in water, can separate the urine rapidly when the urine passes through thesealing liquid without generating an emulsion layer, and can seal the urine smell. Thus, the waterless urinal sealing liquid can effectively prevent the urine smell from escaping into the air so as to achieve the aims of saving
