Abstract
The invention relates to the field of modified asphalt waterproof coiled materials, particularly a nano-carbon-fiber-blended maleic anhydride grafted polyethylene-SBS (styrene-butadiene-styrene) composite modified asphalt waterproof coiled material and a preparation method thereof. The maleic anhydride grafted polyethylene and SBS are compounded to modify the matrix asphalt to enhance the mechanical properties of the matrix asphalt, so that the matrix asphalt has better service performance. The blended modified blast-furnace cinder micropowder and high-polymer base material have favorable compatibility and assist in improving the mechanical properties of the material, thereby effectively lowering the production cost. The added nano carbon fiber and metal aluminum powder enhance the flexibility of the material, endow the material with heat dispersion effect and enhance the heat resistance of the material. The modified asphalt waterproof coiled material has the advantages of high durability, high toughness, cracking resistance, high heat stability, permanent waterproof effect and high water absorptivity. The production process has the advantages of environment friendliness, high efficiency and lower production cost, and thus, has high market competitiveness.
