Preparation and property analysis of polyether polyol two-component rubber repair material

In order to solve the problem that the damage of rubber material cannot be repaired quickly and conveniently, this paper studies a repairing agent that is easy to use and repairs quickly.The modifier is composed of A and B components. The A component can be obtained by blending polyether polyol 330N, chain extender, diethylene glycol, 330NH18 slurry, 330N acetylene black slurry, dioctyl phthalate DOP, catalyst, antioxidant, silane coupling agent and defoaming agent at room temperature and vacuum.The mixture of polyether polyol GE220, 220H18 and dioctyl phthalate DOP, MDI-3051 and MDI-100LL at room temperature and vacuum was used to obtain component B.When using, mix A and B components by 1:0.7-1.3.The repair agent is simple to prepare and easy to use, and can be used for repairing any type of rubber damage. It is not limited by space and shape of rubber parts. It can be formed in 1 minute, have strength in 8 minutes, reach 80% strength in 2 hours and put into use.
