PURPOSE: A modified asphalt waterproof material with a low melting point is provided to prevent the degradation of properties caused by sudden oxidation and aging according to high temperature melting due to a low melting point. CONSTITUTION: A modified asphalt waterproof material with a low melting point comprises 30-40 parts by weight of straight asphalt, 5-10 parts by weight of thermoplastic rubber, 30-40 parts by weight of process oil in which the aromatic component is not added, 5-10 parts by weight of wollastonite, 20-30 parts by weight of dolomite powder, 2-4 parts by weight of UV screen agent, 0.3-0.9 parts by weight of sodium rosinate, and 0.3-0.9 parts by weight of antifoaming agent. The process oil is white mineral oil with specific gravity of 0.83. The Thermoplastic rubber is a styrene-butadiene-styrene copolymer. |
