Description
Technical Field
The invention relates to the field of protection methods of a thin-wall energy-gathering cutting rope, such as moisture prevention, salt spray prevention, mildew prevention and the like, in particular to a method for protecting the thin-wall energy-gathering cutting rope by utilizing a Parylene micro-nano film.
Background
The thin-wall energy-gathering cutting rope is a priming product with a special structural form, and high-temperature and high-speed metal jet flow is formed along the axis of the cutting rope after explosive charge explosion by utilizing the energy-gathering effect of hollow explosive charge to cut a pre-separation surface so as to achieve the purpose of structural separation, as shown in figure 1. The energy-gathered cutting rope can be used for the interstage separation and window ejection of a multi-stage propelling rocket, the valve cutting of a snap shell and the like, and has the characteristics of high reliability, high synchronism, light structural weight and the like.
The length of the thin-wall energy-gathering cutting rope is several meters to dozens of meters, the width is about 2.5 mm-5 mm, the V-shaped angle is 70-90 degrees, the thickness of the thinnest part of the energy-gathering groove is about 100 mu m-200 mu m, and explosives such as hexogen (RDX) or Hexanitrostilbene (HNS) are filled in the thin-wall energy-gathering cutting rope. The thin-wall energy-gathering cutting rope is required to normally work after a series of environmental assessment tests, and test items comprise impact, vibration, bump, temperature-humidity-height (28 days), salt mist, high-temperature exposure, falling and the like, and the storage period of 17 years is required to be met. Wherein the 28-day temperature-humidity-height test is carried out according to the requirements specified in GJB344-87 general design Specification for insensitive electric initiators, and the specific requirements are as follows: two cycles are carried out in a cycle of 24 hours, wherein one cycle mode is normal temperature and normal humidity for 4 hours, high temperature and high humidity (the temperature is 71 ℃, the relative humidity is 95 percent) for 4 hours, and low temperature and negative pressure (the temperature is minus 54 ℃) for 16 hours; the other circulation mode is that the normal temperature and the normal humidity are 4 hours, the low temperature and the negative pressure are 4 hours, and the high temperature and the high humidity are 16 hours, wherein the two circulation modes are alternately carried out for 20 cycles; the tests performed during the remaining 8 days were: continuous low-temperature negative pressure tests are carried out on the 6 th and 7 th days and on the 20 th and 21 st days; the high temperature and humidity test was continued on days 13 and 14 and on days 27 and 28 for a total of 28 days.
Because the temperature and humidity environment tolerance of the currently used organic silicon resin DBSF-6102 three-prevention protective agent is not ideal, and the uniformity of the three-prevention protective agent is not ensured by manual coating, O in the air is generated at the place where the local paint film is thinner2、H2O and CO2Molecules easily penetrate into the interface of the three-proofing protective agent and the thin-walled tube to form a dissolving film locally. The thin-walled tube is easy to corrode and crack during environmental examination and long-term storage, so that water enters the inside of the cutting rope and is directly contacted with the medicament, and the medicament is moistened, hydrolyzed and deteriorated, so that the problem that the cutting rope is abnormally detonated or broken is caused. Therefore, the effective protection of the thin-wall cutting rope directly influences the application of the thin-wall cutting rope in aerospace models, and becomes a technical bottleneck to be solved urgently.
Disclosure of Invention
The invention aims to provide a method for protecting a thin-wall energy-gathering cutting rope by utilizing a Parylene micro-nano film.
The technical solution of the invention is as follows:
a Parylene micro-nano film protection method for a thin-wall energy-gathering cutting rope is characterized in that a chemical vapor deposition method is adopted to uniformly deposit a Parylene film with a micro-nano thickness on the outer surface of the thin-wall energy-gathering cutting rope.
Further, the thickness of the Parylene film is between tens of nanometers and tens of micrometers.

Furthermore, the energy-gathering cutting rope adopts any one of silver, lead-antimony alloy (the content of antimony is 2% or 6%) or copper and the like as a thin pipe material.
Furthermore, the length of the thin-wall energy-gathering cutting rope is about several meters to dozens of meters, the width is about 2.5mm to 5mm, the V-shaped angle is 70 degrees to 90 degrees, and the thickness of the thinnest part of the energy-gathering groove is about 100 mu m to 200 mu m.
Further, the thin-wall energy gathering cutting rope is internally filled with any one of insensitive explosives such as hexogen (RDX) or Hexanitrostilbene (HNS).
Compared with the traditional cutting rope protective agent, the Parylene film protective agent has the following remarkable advantages:
1. the invention prepares the Parylene film by chemical vapor deposition, the deposition temperature is low, the film component is easy to control, the film thickness is in direct proportion to the deposition time, the uniformity and the repeatability are good, and the step coverage is excellent.
2. The Parylene C film has excellent moisture resistance, salt mist resistance, acid resistance and the like, and can meet the protection requirement.
