The invention discloses a
fiber-reinforced bituminous waterproof
sheet material which comprises the following raw materials in parts by weight: 81-90 parts of bitumen, 0.5-1 part of allylsulfocarbamide, 0.6-1 part of ethyl naphthol, 2-3 parts of
calcium aluminate, 2-3 parts of
polybenzimidazole fiber, 1-2 parts of coconut
charcoal fiber, 2-3 parts of
tetrahydrofurfuryl alcohol, 1-2 parts of
barium metaborate, 3-4 parts of
polystyrene, 25-30 parts of diatomite, 0.1-0.2 part of
dicumyl peroxide, 20-30 parts of hydroxyl
silicone oil, 30-40 parts of a 6% NaOH solution, 6-10 parts of alkali
lignin, 2-3 parts of
epoxy chloropropane and 6-8 parts of
petroleum ether. According to the
fiber-reinforced bituminous waterproof
sheet material, provided by the invention, alkali
lignin is subjected to epoxidation treatment, the crosslinking degree of
lignin molecules is increased, and then
polystyrene and fibers are subjected to
hybrid modification, therefore the
surface strength and the water-resisting property of the modified material are improved, and the insulativity, the
mechanical property, the
heat stability and the adhesiveness of finished products are further improved when the modified material is further mixed with epoxidized lignin.
