Abstract

The invention relates to a smokeless sulfur-free display shell lift-off agent and a preparation method thereof, and belongs to the technical field of civil entertainment fireworks. The method is as follows: weighing nitrocellulose, dicyandiamide, sepiolite fiber powder, titanium hydride powder, rare earth photoluminescence powder and a polyurethane adhesive; dividing the polyurethane adhesive intothree parts dissolving the dicyandiamide in hot water to prepare a dicyandiamide solution, spraying the dicyandiamide solution onto the sepiolite fiber powder, simultaneously stirring and drying thesepiolite fiber powder, dropwise adding a first part of polyurethane adhesive into the sepiolite fiber powder, grinding and sieving to obtain dicyandiamide/sepiolite fiber powder; mixing the titaniumhydride powder and the rare earth photoluminescence powder, dropwise adding a second part of polyurethane adhesive, sieving and drying to obtain the light-emitting granulation powder; and mixing the nitrocellulose, the dicyandiamide/sepiolite fiber powder and the light-emitting granulation powder, dropwise adding a third part of polyurethane adhesive, kneading, drying, grinding, sieving and granulating to obtain the smokeless sulfur-free display shell lift-off agent. The smokeless sulfur-free display shell lift-off agent provided by the invention has the advantages of good stability, low costand green and environment-friendly setting-off process.

Description

technical field [0001] The invention relates to a smokeless and sulfur-free fireworks shell lift-off agent and a preparation method thereof, belonging to the technical field of civilian entertainment pyrotechnics. Background technique [0002] Firework bombs are one of the most popular types of fireworks. In large-scale performances, they play an important role in exaggerating the joyful atmosphere. After launching into the air, they will show a variety of flower patterns and amazing effects. Greatly meet people's viewing needs. [0003] However, traditional fireworks bombs are now facing a severe development dilemma. Because their main component is black powder, which has poor stability, safety accidents occur frequently when fireworks bombs are set off, causing great losses to people's property and life safety. At the same time, the fireworks bombs produced serious dust and pungent smell during the discharge process, which polluted our living environment and went against ...
