Abstract
The invention relates to a method for improving interface adhesive property of an HTPB (hydroxyterminated polybutadiene) liner and an NEPE (Nitrate Ester Plasticized Polyether) high-energy propellant. The method comprises the following step: adding a curing catalyst in the HTPB liner, wherein the curing catalyst is one or a combination of triphenyl bismuth (TPB), iron naphthenate, magnesium naphthenate, zinc naphthenate, zinc isoocatanoate, calcium naphthenate or stannous octoate, wherein the adding amount of the curing catalyst accounts for 0.3-2.5 percent the total weight of the HTPB liner. According to the method, the proper curing catalyst is added in the HTPB liner so that the migration loss of the curing catalyst in the interface propellant is compensated, the curing speed of the interface propellant is kept, the adverse influence of external factors to curing and mechanical property of the interface propellant is reduced, and the interface adhesive property of the liner and the propellant is remarkably improved.
