Abstract: A new type of adhesive ZJ-3101 used for bonding NBR insulant has been developed. It is mainly composed or NBR, resorcinol resin and additives. And additive MFA can increase the bonding strength greatly.The colouring agent makes it possible to inspect the shellingout quality of the adhesive. Adhesive ZJ-3101 is of great originalbonding power, and its performance is reliable and stable. It has passed the engine test.The performance test indicates that adhesive ZJ-3101 has great power to bind NBR insulant to solid-propellant rocket engine component made of 30CrMnSiA steel, D6AE steel, titanium alloy, alluminum-magnesium alloy and glass fibre reinforced plastic.
