Embodiment 1

[0008] Embodiment 1: The preparation of described sulfur-free propellant comprises the following steps: take by weight 35 parts of potassium perchlorate, 25 parts of carbon powder, 8 parts of calcium stearate, 5 parts of phenolic resin, 15 parts of hydroxyethyl cellulose Parts, 17 parts of polytetrafluoroethylene. Sieve to mix evenly. If granulation is required, add an appropriate amount of organic solvent, granulate, dry, sieve and pack, and the production is completed.

Embodiment 2

[0009] Embodiment 2: the preparation of described sulfur-free propellant comprises the following steps: take by weight 34 parts of potassium perchlorate, 24 parts of carbon powder, 7 parts of calcium stearate, 4 parts of phenolic resin, 14 parts of hydroxyethyl cellulose Parts, 16 parts of polytetrafluoroethylene. After sieving and mixing evenly, adding an appropriate amount of organic solvent, granulating, drying, sieving and packaging, the production is completed.

Embodiment 3

[0010] Embodiment 3: the preparation of described sulfur-free propellant comprises the following steps: take by weight 36 parts of potassium perchlorate, 26 parts of carbon powder, 9 parts of calcium stearate, 6 parts of phenolic resin, 16 parts of hydroxyethyl cellulose Parts, 18 parts of polytetrafluoroethylene. After sieving and mixing evenly, adding an appropriate amount of organic solvent, granulating, drying, sieving and packaging, the production is completed.

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 [0001] The invention relates to a propellant for fireworks. Background technique [0002] Present fireworks propellant is to use black powder, and the material of black powder contains sulfur. Its main drawback is that the combustion smoke is large and the release of sulfur dioxide and sulfide pollutes the environment. Therefore, in the research and development of black powder substitutes in the industry, vulcanization-free is an important direction. Contents of the invention [0003] In order to solve the above disadvantages, the technical problem to be solved by the present invention is to provide a sulfur-free pyrotechnic propellant. In order to solve the above technical problems, the technical solution adopted in the present invention is a sulfur-free propellant, characterized in that the propellant is composed of the following components in parts by weight: 34 to 36 parts of potassium perchlorate, carbon 24-26 parts of powder, 7-9 parts of calcium s...
