Embodiment Construction

[0038] This embodiment is a preparation method of a slurry without binding agent precipitation.

[0039] The components of the present embodiment syrup are: 0.1% diethanolamine melamine complex, 10% octyl ferrocene, 5% N-N' diphenyl-p-phenylenediamine, 10% industrial quindiol Diisooctyl acid, 19.9% ​​spherical aluminum powder and 55% hydroxyl-terminated polybutadiene. The stated percentages are mass percentages.

[0040] The concrete process of this embodiment is:

[0041] Step 1, pre-baking.

[0042] Put the colloidal diethanolamine-melamine complex and viscous hydroxyl-terminated polybutadiene in a drying room at 50°C±10°C and heat for 12 to 24 hours to reduce the diethanolamine-melamine complex and terminal polybutadiene. The viscosity of hydroxypolybutadiene.

[0043] Step 2, mixing ingredients.

[0044] The pre-dried diethanolamine melamine complex and the hydroxyl-terminated polybutadiene are premixed into a premixed slurry. The mixture is mixed three times, and th...

Abstract

The invention relates to a preparation method of propellant slurry without a precipitated bonding agent. The method comprises the steps of pre-baking hydroxyl-terminated polybutadiene and a diethanolamine melamine complex for 12h or more at 50+ / -10 DEG C so as to reduce the viscosity of the hydroxyl-terminated polybutadiene and the diethanolamine melamine complex; gradually mixing the hydroxyl-terminated polybutadiene with a viscous material by premixing in a small amount for a plurality of times so as to gradually achieve the purpose of evenly pre-mixing the materials; pouring the premixed slurry of the hydroxyl-terminated polybutadiene and the diethanolamine melamine complex into a premix container of the other raw materials for premixing, and fully and evenly mixing. The method guarantees the uniformity of the premixed propellant slurry in the weighing process by utilizing the existing hardware facilities of the process and by means of analysis, explosion and process improvement inthe aspects such as raw material preparation, a premixing process of the propellant slurry and the physical and chemical properties of the raw materials; the method has strong operability; furthermore, the uniformity of the premixed propellant slurry is basically the same, so that the quality of the propellant slurry is improved.

Description

technical field [0001] The invention relates to the field of solid rocket motors, in particular to a method for preparing a slurry without bonding agent precipitation. Background technique [0002] During the production process of a certain type of solid rocket motor, black and brown spots appeared on the drug surface many times, and a small amount of diethanolamine-melamine complex adhered to the material container after cleaning at the mixing station, and the diethanolamine-melamine complex was difficult to completely Problems such as uniform premixing have seriously affected the product quality and production progress of the powder column. [0003] The existing technology is: according to the process requirements, all the bonding agent diethanolamine melamine complexes with a viscosity greater than 20pa.s are added to the hydroxyl-terminated polybutadiene during premixing, and then other components are added, and then premixed by manual stirring , because the diethanolam...
