Self-sticking rubber asphalt adhesive, preparation method thereof and ancient building-dedicated waterproof roll prepared therefrom

Abstract

The invention provides a self-sticking rubber asphalt adhesive, a preparation method thereof and an ancient building-dedicated waterproof roll prepared therefrom. The adhesive is prepared from the following components in parts by weight: 40 to 50 parts by weight of asphalt, 30 to 40 parts by weight of talcum powder, 8 to 14 parts by weight of naphthenic rubber filling oil, 3 to 7 parts by weight of styrene-butadiene-styrene block copolymer, 2 to 6 parts by weight of styrene-isoprene-styrene block copolymer, 3 to 6 parts by weight of self-sticking resin, 1 to 3 parts by weight of plastic modifier and 0.05 to 1 part by weight of stabilizer. The peel strength between the waterproof roll provided by the invention and various types of bases (such as sheathing tiles and fir sheathing boards) is1.0N / mm or more, and the peel strength between the rolls is 1.2N / mm or more.

Description

technical field [0001] The invention belongs to the field of asphalt, and relates to a self-adhesive rubber asphalt compound and a preparation method thereof and a waterproof coil obtained therefrom, in particular to a self-adhesive rubber asphalt compound and a preparation method thereof and a special waterproof coil for ancient buildings obtained therefrom material. Background technique [0002] The roofs of traditional Chinese ancient buildings are mostly covered with small green tiles or tube tiles, and the weight of the roofing materials is relatively large. Once the waterproof design or construction of the roofs of ancient buildings is improper, it is easy to peel off the waterproof membrane or the roof slides, which eventually leads to Damage to architectural heritage. The roof tiles of an ancient building in Shangyu, Zhejiang declined as a whole. The specific reasons were: the protective layer of the waterproof membrane was not stretched across the roof ridge, and t...

AI Technical Summary

Problems solved by technology

[0002] The roofs of traditional Chinese ancient buildings are mostly covered with small green tiles or tube tiles, and the weight of the roofing materials is relatively large. Once the waterproof design or construction of the roofs of ancient buildings is improper, it is easy to peel off the waterproof membrane or the roof slides, which eventually leads to damage to architectural heritage

The roof tiles of an ancient building in Shangyu, Zhejiang declined as a whole. The specific reasons were: the protective layer of the waterproof membrane was not stretched across the roof ridge, and the SBS waterproof membrane was sensitive to temperature, and the adhesive material softened when heated, which eventually caused the entire roof tile slide

[0003] At present, the commonly used waterproofing membrane is asphalt waterproofing membrane. The cost of asphalt waterproofing membrane is low, but there are disadvantages such as poor temperature stability, easy to flow at high temperature, easy to be brittle at low temperature, poor aging resistance, and short service life. Most of it can be attributed to the poor high and low temperature stability of the asphalt layer in the waterproof membrane, and the peel strength of the asphalt layer is small, and the shear strength is not enough.

CN101121874A discloses a high heat-resistant self-adhesive rubber asphalt waterproofing coiled material. The modified asphalt layer contains mineral powder and more than two kinds of tackifiers. Although the waterproofing coiled material still has bonding performance above 100°C, its The peel strength is not high enough, and the problem of low temperature flexibility is not considered, and the application range is narrow
