Problems solved by technology

SBS composite materials can be used as elastic shock-absorbing materials, but their strength and elastic properties are not up to the requirements of use. In the industry, inorganic reinforcing phases are often filled to improve their performance, but the surface of the inorganic filling phase is hydrophilic and oleophobic. Large energy and easy agglomeration between particles make it difficult to disperse uniformly in the organic matrix and the binding force with the matrix is ​​weak, resulting in poor strength of the material and unsatisfactory elastic properties

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a preparation method of an elastic shock-absorbing SBS material. Background technique [0002] Styrene-butadiene-styrene block copolymer (SBS) is a tri-block copolymer of styrene and butadiene as monomers, which has the characteristics of plastic and rubber, and is called "third-generation synthetic rubber". Similar to styrene-butadiene rubber, SBS can be in contact with water, weak acid, alkali, etc. It has excellent tensile strength, large surface friction coefficient, good low-temperature performance, and good processing performance. It has become the most consumed thermoplastic elastomer at present. SBS composite materials can be used as elastic shock-absorbing materials, but their strength and elastic properties are not up to the requirements of use. In the industry, inorganic reinforcing phases are often filled to improve their performance, but the surface of t...
