Embodiment 1

[0038] Add 5g of SBR to 40g of petroleum asphalt, add 6g of thermoplastic styrene-butadiene rubber and 2g of powdered styrene-butadiene rubber when the temperature rises to 120°C, and stir for 2 hours. After the temperature rises to 140°C, enter the colloid mill for grinding, and grind for three times Add 1g of coumarone resin, 0.2g of petroleum resin, 0.5g of terpene resin, 1g of small molecular weight polyisobutylene, stir at 140°C±5°C for 2 hours, add 9g of calcium carbonate, 0.05g of ultraviolet absorber UV-531, 0.03g Di-tert-butyl-p-cresol, stirred for 2 hours to make self-adhesive rubber asphalt.

Embodiment 2

[0040] Add 12g of three oils to 48g of petroleum asphalt, add 10.5g of thermoplastic styrene-butadiene rubber and 3g of powdered styrene-butadiene rubber when the temperature rises to 150°C, and stir for 1 hour. After the temperature rises to 175°C, enter the colloid mill for grinding, and circulate for three times , add 2g coumarone resin, 0.6g petroleum resin, 1.25g terpene resin, 1.25g small molecular weight polyisobutylene, stir at 180°C±5°C for 1 hour, add 13.5g calcium carbonate, 1g ultraviolet absorber UV-531, 0.5g di-tert-butyl-p-cresol, stirred for 1 hour to make self-adhesive rubber asphalt.

Embodiment 3

[0042] Add 15g of three oils to 60g of petroleum asphalt, when the temperature rises to 180°C, add 15g of thermoplastic styrene-butadiene rubber, 4g of powdered styrene-butadiene rubber, stir for 0.5 hours, after the temperature rises to 200°C, enter the colloid mill for grinding, and circulate for three times , add 3g coumarone resin, 1g petroleum resin, 2g terpene resin, 1.5g small molecular weight polyisobutene, stir at 200℃±5℃ for 0.5 hours, add 18g calcium carbonate, 2g ultraviolet absorber UV-531, 1g di-tert Butyl p-cresol, stirred for 0.5 hours to make self-adhesive rubber asphalt.

[0043] The temperature of the self-adhesive rubber asphalt prepared in Examples 1 to 3 is lowered to 150±5°C, and the low-temperature-resistant self-adhesive rubber asphalt waterproof roll is made through processes such as release paper unfolding, self-adhesive coating, cooling, film coating, and cooling and setting. material, and the peel strength is shown in Table 1 below.

Abstract

The invention provides a rubber bitumen waterproof roll with low temperature resistance and auto-cohesive performance. Modified bitumen layer contains calcium carbonate and more than two kinds of adhesive, which solves the problem that the prior auto-cohesive rubber bitumen waterproof roll can not work under temperature below 5 DEG C, while the invention has good cohesive performance and can work well even under the temperature 10 DEG C under zero, and the stripping intensity is as high as 1.0N/mm.

Description

technical field [0001] The invention relates to a low-temperature-resistant self-adhesive waterproof coiled material, in particular to a self-adhesive rubber asphalt waterproof coiled material capable of self-adhesive construction at low temperature (-10°C). Background technique [0002] At present, the known self-adhesive construction method self-adhesive rubber asphalt waterproofing membrane is based on elastomer modified asphalt such as SBS, and strong waterproof polyethylene film or aluminum foil is used as the upper surface material of the membrane or without membrane (double-sided self-adhesive). ), a tireless self-adhesive waterproof membrane made of peelable silicon-coated film or silicon-coated crepe paper as the material of the lower surface release layer. The product implements the national industry standard of JC840-1999 "self-adhesive rubber asphalt waterproof membrane". [0003] The above known self-adhesive rubber asphalt waterproofing membrane has the follow...
