Description
Technical field
The invention belongs to adhesive area, relate in particular to the high-strength SEBS tackiness agent of a kind of heatproof/environmental protection type high viscosity and preparation method.
Background technology
SEBS is thermoplastic elastomer SBS's hydrogenation products, often is called Hydrogenated SBS.SEBS is take polystyrene as end segment, the ethylene-butene copolymer that obtains take the polyhutadiene hydrogenation as in the middle of the linearity three embedding multipolymers of elastomeric block.SEBS does not contain unsaturated double-bond, therefore has satisfactory stability and ageing resistance.
SBS is a kind of polystyrene plasticity-elastomerics of excellence, needn't namely have the physical properties of similar vulcanized rubber through sulfuration, but the direct injection moulding, and one of can percentage hundred recycle, be widely used in each field.But contain a large amount of aliphatic double bonds on the SBS main chain, not good, deteriorated easily to the resistivity of weather, ultraviolet money, ozone and heat, the Application Areas that has seriously restricted the SBS sizing agent is widened.Therefore, s-generation polystyrene thermoplastic elastomer SEBS arose at the historic moment in 1972.
SEBS utilizes the hydrogenation mode with the double-stranded saturation of aliphatics, to enlarge the range of application of product.Saturation type thermoplastic elastomer SEBS since soft section be the alkene architecture of saturation type, weathering resistance, heat-resistant aging are better than SBS, and physical property is also more tough than SBS, so range of application is more extensive.
Through widely applying practice to find that it is poor that common SBS glue exists environmental-protecting performance, bonding strength is low, anti-old/problem such as heat-resistingization index is undesirable.
Summary of the invention
