The invention relates to gunpowder, in particular to the gunpowder for a traffic safety warning torch annunciator. The gunpowder is formed by mixing the following raw materials in percentage by weights: 55% of strontium nitrate, 13% of potassium perchlorate, 5% of polrvinyl chloride, 5% of phenolic resin, 2% of yellow granular sand, 10% of atoleine, and 10% of sulphur. The gunpowder for the traffic safety warning torch annunciator has a long combustion time, a high wind resistance, and a sighting distance can reach more than 1200 meters.
Description
technical field [0001] The invention relates to a gunpowder, in particular to a gunpowder for a traffic safety warning torch signal. Background technique [0002] Signal torches are developed from bonfires. A long time ago, when a train stopped suddenly due to an accident, in order to prevent the subsequent or coming trains from colliding, a fire was lit to warn. Due to the continuous development of science and technology, the method of temporarily igniting combustibles is changed to a solid special object, which gradually evolves into the current signal torch. [0003] Signal torch, warning with red light. When the train suddenly stops halfway due to an accident at night, in order to prevent the subsequent or coming trains from colliding; or when there are a series of problems affecting the train such as railway damage, roadbed damage, trees or other objects blocking the railway at night, it will be ignited The signal torch is used to warn; for this reason, the signal to...
