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

A preparation method of a syrup without bonding agent precipitation, pre-baking the hydroxyl-terminated polybutadiene and diethanolamine melamine complex at 50°C±10°C for more than 12 hours to reduce the concentration of hydroxyl-terminated polybutadiene and diethanolamine Viscosity of the melamine complex; through a small amount of premixing multiple times, the hydroxyl-terminated polybutadiene is gradually blended with the viscous material, and the purpose of premixing it is gradually achieved; the hydroxyl-terminated polybutadiene and diethanolamine The melamine complex premixed slurry is poured into other raw material premix containers to participate in premixing, and fully stirred. The present invention utilizes the existing hardware facilities of the process, and improves the process through the analysis and exploration of the preparation of raw materials, the premixing process of the drug slurry, and the physical and chemical characteristics of the raw materials, so as to ensure the uniformity of the premixed drug slurry in the weighing process, and has the advantages of The operability is strong, and the uniformity of the pre-mixed slurry is basically the same, which ensures the quality of the slurry.

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...
