A kind of method and product for improving TMXDI HTPB Propellant Processing Characteristics is that process auxiliaries ZnAR is added in the system, and the mass percentage content which accounts for HTPB propellant is 0.01% ~ 0.2%.The mixing temperature of medicine slurry, the addition time of premature cure agent are improved simultaneously.The present invention can significantly improve the processing performance using TMXDI as the propellant of curing agent in the case where not increasing total incorporation time, improve production efficiency, and propellant has preferable mechanical property, the needs of practical application can be met, be to substitute toxic curing agent TDI or IPDI with less toxic curing agent TMXDI to lay the foundation.
Description
Technical field
The present invention relates to propellant technical field, more particularly to a kind of solid propellant rocket motor charge fourth hydroxyl
Propellant formulation and its hybrid technique.
Background technology
Country's end hydroxy butadiene (being commonly called as fourth hydroxyl) propellant is generally with toluene di-isocyanate(TDI) (TDI) and different Buddhist at present
Your ketone diisocyanate (IPDI) is curing agent.Wherein, TDI is severe poisonous chemicals, has strong mucous membrane irritation and lures by force
Denaturation, and IPDI invades body toxicity on inhalation category hypertoxic type through respiratory tract and skin.Also, it is tight that TDI synthesis technologies are related to pollution
The nitration reaction and phosgenation reaction of weight, using a large amount of nitration mixture and the phosgene of severe toxicity in preparation process, and IPDI synthesis technologies make
With severe toxicity and fatal raw material hydrogen cyanide and phosgene.Therefore, TDI and IPDI is for physico-chemical property or synthesis technology,
Green requirement is not met, is all restrained by National Environment Policy Act, regulation is restricted, and increases China's missile armament Project R＆D
With the risk of production.Therefore, it is badly in need of carrying out the research that HTPB propellant substitutes TDI and IPDI with novel non-toxic green curing agent,
To meet the requirement of the less toxic Non-toxic in China's HTPB propellant powder charge process.
Tetramethylxylylene diisocyanate (abbreviation TMXDI) is a kind of to be permitted through U.S.'s food and Drug Administration
Can, it is almost non-hazardous to human body available for the curing agent of packaging material for food, and it is without the use of nitration mixture and play in its building-up process
Cytotoxic compound is a kind of ideal green curing agent.Its structural formula is as shown in Equation 1.
TMXDI has meta position (m-) and aligns (p-) two kinds of isomers, is white crystal, fusing point 72 under p-TMXDI room temperature
DEG C, it is colourless liquid under m-TMXDI room temperature, solidification point is -10 DEG C.TMXDI used is m-TMXDI in the present invention.TMXDI's
NCO group is not conjugated on the methylene being connected with phenyl ring with phenyl ring, therefore its spy with both aliphatic and aromatic series
Point, elastomer obtained have higher intensity, elasticity and durability.Hydrogen atom quilt on the methylene being connected with NCO group
After methyl substitution, ultraviolet-resistant aging and hydrolytic stability are improved, the effect of hydrogen bond is reduced, increases elongation.And
Due to the influence of steric hindrance, the reactivity of TMXDI weakens, and reduces sensibility of the curing agent to water, and working life extends.Base
In these advantages, TMXDI is applied to have good prospect in propellant.
Only the fewer companies such as U.S. Cytec industrial groups can carry out industrialized production to TMXDI at present, and the U.S. is earlier than last century
Application studies of the TMXDI in HTPB propellant is just carried out the eighties, U.S.'s Naval Weapons Center, China Lake, California is at one
In the research that hypertoxic type compound substitutes in propellant, preferably TMXDI substitutes the IPDI curing agent applied in propellant, by right
Than they think, TMXDI is not only less toxic, also have mechanical property comparable with IPDI and price.But it is external almost without with
TMXDI is the research in terms of the HTPB propellant processing performance of curing agent.Domestic related TMXDI researchs be concentrated mainly on synthesize and
Civilian aspect, applications of the TMXDI in HTPB propellant are not yet carried out, and its application in HTPB propellant stands in the breach and is
The processing performance using TMXDI as the HTPB propellant of curing agent is solved, because the reactivity of TMXDI is poor, if only carrying out
Simple curing agent substitutes, and the processing performance of the propellant containing TMXDI is very poor, can not carry out adherent cast.Therefore, to carry out
Applications of the TMXDI in propellant needs to solve first the processing performance using TMXDI as the propellant of curing agent.
