Embodiment Construction

[0040] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0041] Table 2 is the acetone consumption during the anti-caking additive formula of embodiment 1~embodiment 4 and preparation, and its preparation method is:

[0042] ① Mix surfactant and plasticizer with acetone solution;

[0043] ② Mix the above mixture with the inert nanocarrier and stir until the inert nanocarrier is completely wetted;

[0044] ③Acetone is removed by vacuum drying to obtain the finished product.

Abstract

The invention discloses an anti-blockingaccessory ingredient for a gas production drugoxidizing agent and a preparation method of the anti-blocking accessory ingredient, which belong to the technical field of gas production drugs for producing gas for explosion or propulsion. The anti-blockingaccessory ingredient is at least prepared from an inert nano-carrier with the component being silicon dioxide powder, a surface active agent and a plasticizer; the mass ratio of the inert nano-carrier to the surface active agent is 5:3.5 to 5:4.5; the mass ratio of the nano-carrier to the plasticizer is 5:1.5 to 5:2.5. The anti-blockingaccessory ingredient can prevent ammonium perchlorate powder from absorbing moisture and caking during a conventional storage process, and solves the problem that ammonium perchlorate cannot be stored for a long time when being used as an oxidizing agent.

Description

technical field [0001] The invention relates to the technical field of a gas-generating agent for generating gas for explosion or propulsion, in particular to an anti-caking additive for an oxidant of a gas-generating agent and a preparation method thereof. Background technique [0002] Gas-generating drugs are used to generate gas for explosion, propulsion, or filling expansion under the conditions of heating, combustion or collision, and have been widely used in civil fields, such as safety airbags on traffic equipment. When a car collides, the gas produced quickly fills the airbag itself, making it inflated to protect and buffer people from impact damage. It is also like the signal flares used in mountaineering, navigation and other fields, which are filled with gas-producing drugs. The gas is generated under the open condition to propel the flare itself to launch and advance a certain distance, so that the signal can be clearly and continuously transmitted. [0003] Tra...
