Problems solved by technology

At present, domestic ignition powder mainly includes LDNP-KClO 4 series and the current series of potassium picrate and KK medicine, but the LDNP, potassium picrate and KK medicine used in the manufacture of ignition powder will produce a large amount of waste water during the production process, and a series of toxic gases and other substances that pollute the environment will be produced during use Harmful to human health, and the accuracy of the ignition time of the existing ignition powder is low, so the development of a high-precision, environmentally friendly ignition powder has become a top priority for domestic civil explosives enterprises

Embodiment Construction

[0013] Embodiments of the present invention: the novel ignition charge, calculated in parts by mass, includes 40-98 parts of nickel hydrazine nitrate, 1-30 parts of lead dioxide, 1-30 parts of zirconium powder and 100-150 parts of binder. Prepare ingredients.

[0014] The adhesive is a nitrocellulose butyl acetate solution with a mass percentage of 1-10%, or a polyvinyl alcohol aqueous solution with a mass percentage of 3-16%.

[0015] The preparation method of novel ignition charge, each component is taken by above-mentioned mass parts, comprises the following steps:

[0016] 1) Put the adhesive into a mixing container, add lead dioxide and zirconium powder to the adhesive to obtain product A;

[0017] 2) Add nickel hydrazine nitrate to product A again to obtain product B;

[0018] 3) Place the mixing container under the mixing machine, and the stirring paddle goes deep into the liquid surface of the container. After the person leaves the mixing room, start the mixer, stir ...

Abstract

The invention discloses a novel electric ignition fusehead and a preparation method thereof. The novel electric ignition fusehead comprises the following raw materials in parts by weight: 40-98 parts of nickel hydrazine nitrate, 1-30 parts of lead dioxide, 1-30 parts of zirconium powder and 100-150 parts of an adhesive. According to the invention, nickel hydrazine nitrate is adopted as a basic material for preparing the ignition fusehead, thereby substantially improving the environmental friendliness of the ignition fusehead; in addition, the time accuracy of ignition of the ignition fusehead is high, and nickel hydrazine nitrate used for preparing the ignition fusehead is damp gunpowder, thereby improving the inherent safety of the production process.

Description

technical field [0001] The invention relates to the technical field of civil explosives, in particular to a novel ignition charge and a preparation method thereof. Background technique [0002] The electric ignition charge is the core part of the electric detonator and the ignition mechanism of the electronic detonator, and is a key component that affects the reliability of the ignition of the electric detonator. At present, the domestic ignition powder mainly includes LDNP-KClO 4 series and the current series of potassium picrate and KK medicine, but the LDNP, potassium picrate and KK medicine used in the manufacture of ignition powder will produce a large amount of waste water during the production process, and a series of toxic gases and other substances that pollute the environment will be produced during use It is harmful to human health, and the ignition time accuracy of the existing igniting powder is low, so developing a high-precision, environmentally friendly igni...
