Description
Technical Field
The invention relates to a novel self-healing brominated butyl rubber/natural rubber blending modification system and a preparation method thereof, belonging to the technical field of rubber modification.
Background
The butyl rubber is prepared by polymerizing and copolymerizing more than 97% of polyisobutylene and less than 3% of polyisoprene through cations, the highly saturated alkane-like structure endows the high solvent resistance, aging resistance and other performances, and the symmetrical side methyl enables the high air tightness to be kept while the high air tightness is kept without crystallization, so that the butyl rubber is widely applied to the fields of tire inner tubes, sealing rings and the like.
The self-healing method of the high polymer material comprises two methods of external aid type healing and intrinsic type healing. By exo-healing is meant the repair of a damaged area by external or internal supplementation of substances or energy after the material has been damaged, such as the addition of healing agents (unreacted reactants and catalysts) to the material, which reactants begin to react after the wound has been inflicted, in such a way that the substance is consumed, and loses its self-healing properties after many damages. The latter is a mode of re-assembly, bonding at the damaged site, even spontaneously, with only the supply of energy (heating, light, etc.) by means of reversible covalent bonds and supramolecular interactions (ionic, hydrogen, coordination, Π - Π interactions, van der waals forces, etc.), the process involving only energy transmission. The first method is relatively easy to actually operate and has been applied to road materials such as asphalt, but the healing agent (i.e. unreacted reactant and catalyst) is gradually consumed after being damaged many times, and the self-healing performance of the material is correspondingly lost, which greatly limits the development prospect. Reversible covalent bond-type intrinsic healing is generally thermoreversible, requiring temperature regulation, i.e., heat supply. The supermolecule type intrinsic healing does not need to consume a healing agent and a matrix material, and does not need external energy action. The self-healing mode is gradually developed along with the proposal of supramolecular chemistry and system research, and becomes the main form and development direction of self-healing material research. However, the existing internal healing materials have the problems which are difficult to overcome, such as insufficient mechanical properties, insufficient self-healing performance and the like.
Patent CN202111133764 discloses a production process capable of automatically repairing a butyl rubber inner tube, wherein a carbon/nitrogen organic compound is added in a final refining process of the production process of the butyl rubber inner tube, and the carbon/nitrogen organic compound and bromine react to enable a system to have an ionic interaction, so that sheared brominated butyl rubber can be self-healed, a completely cut sample can keep the original characteristics after the self-healing process is applied, the self-repairing capability of the butyl rubber inner tube is improved, and the repairing speed is accelerated.
The patent CN202011396956 discloses a high-strength self-healing rubber material and a preparation method thereof, wherein a polyethylene polymer graft modified boron nitride nanosheet with a pyridine vinyl monomer is obtained by carrying out free radical polymerization on the boron nitride nanosheet and the pyridine vinyl monomer, and a dynamic ionic cross-linking bond can be formed when the boron nitride nanosheet is uniformly dispersed in a halogenated butyl rubber matrix through a mechanical blending method, so that the finally obtained rubber material is endowed with high tensile strength and high self-healing performance, and the preparation method is simple in process and easy to realize large scale.
The patent CN202210743399 discloses a conductive self-healing rubber support and a crack overhauling method thereof, wherein a rubber support body comprises a rubber support part and a rigid support part which are connected with each other, and the rubber support part is made of a conductive self-healing rubber material; the electrode is connected with an external power supply and used for changing the structure of the rubber support piece under the electrified condition so as to enable the crack in the rubber support body to be self-healed; the problem of among the prior art can't guarantee that the support normally uses and the durability of support satisfies original design requirement all the time in the life cycle of building structure and bridge structures is solved.
