Description

technical field [0001] The invention relates to the technical field of modification of SBS composite materials, in particular to a high heat-resistant sisal fiber modified SBS composite material and a preparation method thereof. Background technique [0002] Sisal belongs to Agaveaceae and is a widely planted perennial hemp economic plant. The sisal fiber obtained from its leaves has white color, seawater corrosion resistance, tough texture, low density, high tensile strength and modulus, The source is wide and the price is low. Therefore, sisal fiber has obvious advantages in the preparation of high-strength, high-modulus and low-cost fiber-reinforced polymer matrix composites. [0003] Styrene-butadiene-styrene block copolymer (SBS) is a block copolymer of styrene as a monomer, which has the characteristics of plastic and rubber, has good chemical stability, excellent low temperature performance, low price and It is one of the important general-purpose plastics in the ind...
