Abstract

The invention discloses a self-glued asphalt adhesive material, a preparation method of the self-glued asphalt adhesive material, and a self-glued asphalt waterproof coiled material. A raw material formula of the self-glued asphalt adhesive material comprises the following ingredients of petroleum asphalt, naphthenic oil, tackifying resin, butadiene styrene rubber and/or modified butadiene styrene rubber, polyethylene wax, elastomer polymers and filing materials. By using the high-initial-viscosity and high-heat-resistance self-glued asphalt adhesive material as a bonding layer for bonding the self-glued waterproof coiled material and a base layer (such as a roof); the polyethylene wax in the bonding layer and the petroleum asphalt take a crosslinking reaction, so that the heat resistance performance of the self-glued asphalt adhesive material is improved. The self-glued asphalt adhesive material has good bonding performance, and is fully bonded with the base layer, so that the bonding is firm; in addition, the heat resistance being higher than 90 DEG C can be born; the low-temperature flexibility reaches -30 DEG C; the self-glued asphalt adhesive material has high heat-resistance performance, so that the requirements of facade construction using the waterproof coiled material as the waterproof layer can be met; in addition, the softening overflowing of the self-glued asphalt adhesive material can be prevented. The waterproof requirements of the base layer in various climates can be almost met; the hot melting construction is not needed.
