Safety Research of New Release Agent in Production

The paper aims to analyze the security of new release agent (B release agent) in the production process. Starting with the composition, stability and safety of the new release agent, the security of the new release agent is theoretically verified by means of infrared detection, DSC thermal analysis and solubility test. Polyurethane release agent (A release agent) and B release agent are applied on different models, the ejection force of the two release agents in the production process and the burn rate of the solid motor are compared and analyzed, their technical feature and influence on burn rate of the motor are explored, and the reliability of the new release agent in the production of the solid motor is verified from the practical application. By comparing the infrared spectrum, DSC spectrum and solubility, it is found that the effective components of B release agent are the same as that of A release agent, and B release agent has good thermal stability. The results of process performance of B release agent show that it has good molding ability. Two kinds of release agents are used to test the ejection force and burn rate, and it is found that B release agent can greatly reduce the ejection force in the production process, and B release agent has no effect on the burn rate. B release agent has good security in the production process of solid motor and can be widely used.
