Abstract
The invention discloses sulfur-free propellant powder composed of the following components in parts by weight: 34-36 parts of potassium perchlorate, 24-26 parts of carbon powder, 7-9 parts of calcium stearate, 4-6 parts of phenolic resin, 14-16 parts of hydroxyethyl cellulose and 16-18 parts of polytetrafluoroethylene. The propellant powder contains no sulfur components so that environment pollution caused by sulfur dioxide and sulfide is eliminated when fireworks are displayed; no restricted articles are contained, so that the environment-friendly property is greatly improved; the emission performance is better than that of the traditional black powder under the same working condition; all safety performance indexes such as shock sensitivity and friction sensitivity are excellent, so that potential safety hazards are fundamentally reduced; and the propellant powder is low in moisture rate, favorable in storage stability and capable of overcoming the defect that the black powder easily absorbs moisture.
Description
Technical field
The present invention relates to a kind of fireworks propelling charge.
Background technology
Current firework launching medicine uses black powder, containing sulphur in the materials of black powder.Its major drawbacks is that combustion fumes is large and releases sulfurous gas and sulphide staining environment.So the research and development of the black powder substitute of carrying out in the industry are important directions without sulfuration.
Summary of the invention
In order to solve above-mentioned drawback, technical problem to be solved by this invention is, provides a kind of without sulphur fireworks launch medicine.In order to solve the problems of the technologies described above, the technical solution used in the present invention is, a kind of without sulphur propelling charge, it is characterized in that, described propelling charge is made up of the component of following portions by weight ratio: potassium perchlorate 34 ~ 36 parts, carbon powder 24 ~ 26 parts, calcium stearate 7 ~ 9 parts, 4 ~ 6 parts, resol, Natvosol 14 ~ 16 parts, tetrafluoroethylene 16 ~ 18 parts.
Preferably, described propelling charge is made up of the component of following portions by weight ratio: potassium perchlorate 35 parts, carbon powder 25 parts, calcium stearate 8 parts, 5 parts, resol, Natvosol 15 parts, tetrafluoroethylene 17 parts.
