Description

Technical field [0001] The present invention relates to the technical field of SBS composite material modification, and more specifically, to a SBS composite material modified by aging resistant sisal fiber. Background technique [0002] Sisal belongs to the Agave family and is a widely cultivated perennial economical plant. The sisal fiber taken from its leaves has a white color, is resistant to seawater corrosion, has tough texture, low density, high tensile strength and modulus. It has a wide range of sources and low price. Therefore, sisal fiber has obvious advantages for preparing high-strength, high-modulus and inexpensive fiber-reinforced polymer-based composites. [0003] Styrene-butadiene-styrene block copolymer (SBS) is a block copolymer with styrene as monomer. It has the characteristics of plastic and rubber, has good chemical stability, excellent low-temperature performance, and low price. It is one of the important general-purpose plastics in the industry due to its ...
