Abstract
The invention discloses and belongs to the field of ammonia ester elastomers, and particularly relates to an oil-resistant and heat-resistant cross-linking type ammonia ester elastomer composite and a preparation method thereof. Liquid hydroxyl terminated butyl nitrile rubber is selected as a polyurethane urea elastomer soft segment modified material, and the heat resistance of the material can be easily improved due to the three unique structures of the material that firstly, a carbon chain serves as the molecular main chain of the material, wherein the heteroatom of the molecular main chain of the high polymer material is usually degraded first at a high temperature, -O-, -N- and other heteroatom do not exist in the main chain, and then the stability of the material is much higher; secondly, oxygen atoms having a hydrogen bonding effect with active hydrogen atoms in urea bonds or urethane bonds of hard segments do not exist in the molecular main chain of the material, wherein the hydrogen bonding effect between polyurethane soft segment molecules and hard segment polar bonds is quite weak, and the thermal sensitivity in macro-mechanical properties of polyurethane elastomers is low; thirdly, a small number of unsaturated double bonds are contained in the molecular main chain of the material and can serve as potential reaction points, and therefore the reaction points and the cross-linking agent can easily react to form the cross-linking structure, the movement of high molecular chains is limited by chemical cross-linking of the molecular chains, and therefore the thermal stability of the polyurethane elastomers is improved. The thermal resistance of polyurethane urea elastomers synthesized by the composite is greatly improved.
