Example Embodiment
[0012] Example 1:
[0013] A kind of asphalt phenolic waterproof material, the composition of which is expressed in parts by mass: 100 parts of petroleum pitch; 10 parts of pine tar; 15 parts of glycerin rosin ester; 1 part of calcium chloride; 12 parts of rosin modified phenolic resin; iron oxide 20 parts of yellow; 40 parts of solvent gasoline; 10 parts of aluminum-silver paste; 30 parts of benzene; 6 parts of silica; 8 parts of xylene; 1 part of butanol; 2 parts of ethylene diamine. Put the pitch into a reaction kettle and heat to 150 degrees Celsius to dissolve, add the remaining components at 160 degrees Celsius, and stir for 1 hour to obtain the product.
[0014] Product surface dry for 3.2h, hard-dry for 22h; resistant to low temperature of -50℃, no foaming and no flow at 100℃ for 4h; water impermeability 0.1MPa.
Example Embodiment
[0015] Example 2:
[0016] A kind of asphalt phenolic waterproof material, its composition is expressed in parts by mass: 100 parts of petroleum pitch; 25 parts of pine tar; 20 parts of glycerin rosin ester; 2 parts of calcium chloride; 18 parts of rosin modified phenolic resin; iron oxide 30 parts of yellow; 60 parts of solvent gasoline; 18 parts of aluminum silver paste; 40 parts of benzene; 8 parts of silica; 10 parts of xylene; 2 parts of butanol; 3 parts of ethylene diamine. Put the pitch into a reaction kettle and heat to 150 degrees Celsius to dissolve, add the remaining components at 160 degrees Celsius, and stir for 1 hour to obtain the product.
[0017] Product surface dry for 2.5h, hard-dry for 21h; resistance to low temperature of -50℃, no foaming or flow at 110℃ for 4h; impermeability of 0.15MPa.
Example Embodiment
[0018] Example 3:
[0019] A kind of asphalt phenolic waterproof material, its composition is expressed in parts by mass: 100 parts of petroleum pitch; 15 parts of pine tar; 17 parts of glycerin rosin ester; 1.5 parts of calcium chloride; 15 parts of rosin modified phenolic resin; iron oxide 25 parts of yellow; 50 parts of solvent gasoline; 14 parts of aluminum silver paste; 35 parts of benzene; 7 parts of silica; 9 parts of xylene; 1.5 parts of butanol; 2.5 parts of ethylenediamine. Put the pitch into a reaction kettle and heat to 150 degrees Celsius to dissolve, add the remaining components at 160 degrees Celsius, and stir for 1 hour to obtain the product.
[0020] The product is surface-dried for 2.2h, hard-drying for 20h; resistant to low temperature of -50℃, no foaming and no flow at 120℃ for 4h; water impermeability 0.2MPa.
[0021] All the components in the above examples are commercially available.
