Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
SEBS
The term "SEBS" as used herein refers to a linear triblock copolymer having polystyrene as the terminal block and an ethylene-butene copolymer obtained by hydrogenation of polybutadiene as the middle elastomeric block. The basic performance characteristics of SEBS in triblock configuration are: firstly, the molecular chain is formed by embedding a soft elastic polybutadiene segment with the glass transition temperature lower than room temperature and a hard plastic polystyrene segment with the glass transition temperature higher than room temperature; secondly, the two blocks are not thermodynamically compatible and form a two-phase separated "sea-island structure" with microscopic-scale phase separation. When the polystyrene content is low, the polystyrene is divided into isolated domains surrounded by a polybutadiene continuous phase of rubber. Due to the existence of the plastic phase, the movement of the rubber molecular chain segment is limited, so that the thermoplastic elastomer has the performance of vulcanized rubber. Except that the crosslinking of the plastic phase is reversible physical crosslinking, and when the plastic phase is dissolved in an organic solvent or heated to be molten, the plastic phase is dissolved or molten, and the crosslinking effect is lost; after the solvent is evaporated or the melt is cooled, the plastic phase separates again and precipitates and returns to the original physical cross-linked state. The elastomer block in the SEBS is completely hydrogenated, so that the SEBS has excellent weather resistance, good tolerance to ozone, ultraviolet rays and electric arcs, low-temperature resistance, good flexibility at the temperature of-60 ℃ and the like; therefore, the SEBS has excellent rubber elasticity, excellent weather resistance, low temperature resistance, environmental protection performance and the like. In a preferred embodiment of the present invention, the SEBS is in a powder form, and the degree of hydrogenation is > 95%.
Polyurethane elastomer
The term "polyurethane elastomer" as used herein means a polyurethane elastomer prepared by reacting polytetrahydrofuran diol with polyisocyanate to obtain a prepolymer and then adding cyclodextrin as a chain extender.
The term "polyisocyanate" used in the present invention is selected from those commonly used in the art, such as aromatic diisocyanate compounds, e.g., toluene diisocyanate, diphenylmethane diisocyanate, m-xylylene diisocyanate, m-phenylene bis (dimethylmethylene) diisocyanate, etc.; aliphatic or alicyclic diisocyanate compounds such as hexamethylene diisocyanate, lysine diisocyanate, 1, 3-bis (isocyanatomethyl) cyclohexane, 2-methyl-1, 3-diisocyanatocyclohexane, 2-methyl-1, 5-diisocyanatocyclohexane, 4' -dicyclohexylmethane diisocyanate and isophorone diisocyanate. In a preferred embodiment, the polyisocyanate is one of HDI, MDI and IPDI; preferably, the polyisocyanate is HDI or MDI.
The term "cyclodextrin" as used in the present invention is alpha-cyclodextrin, beta-cyclodextrin and derivatives thereof. The cyclodextrin derivative in the present invention is chemically modified cyclodextrin, such as amino modification, methyl modification, propyl modification, triacetyl modification, monoacetyl modification, tosyl modification and sulfonyl modification.
A preparation method of a polyurethane elastomer comprises the following steps:
(1) a certain amount of beta-cyclodextrin and 40ml of DMF were weighed into a schlenk tube with a volume of 80ml, and stirred magnetically under the condition of an oil bath at 80 ℃ and Ar atmosphere.
