Embodiment 1

[0038] Add 5g minus three oil to 40g petroleum pitch, add 6g thermoplastic styrene butadiene rubber and 2g powder styrene butadiene rubber when the temperature is raised to 120℃, stir for 2 hours, after the temperature rises to 140℃, enter the colloid mill to grind, and grind it three times. Add 1g coumarone resin, 0.2g petroleum resin, 0.5g terpene resin, 1g low molecular weight polyisobutylene, stir at 140℃±5℃ for 2 hours, add 9g calcium carbonate, 0.05g ultraviolet absorber UV-531, 0.03g Di-tert-butyl-p-cresol is stirred for 2 hours to make self-adhesive rubber asphalt.

Embodiment 2

[0040] Add 12g minus three oil to 48g petroleum pitch, add 10.5g thermoplastic styrene butadiene rubber and 3g powder styrene butadiene rubber when the temperature is raised to 150℃, stir for 1 hour, after the temperature rises to 175℃, enter the colloid mill for grinding, and grind it three times , Add 2g coumarone resin, 0.6g petroleum resin, 1.25g terpene resin, 1.25g low molecular weight polyisobutylene, stir at 180℃±5℃ for 1 hour, add 13.5g calcium carbonate, 1g ultraviolet absorber UV-531, 0.5g of di-tert-butyl p-cresol is stirred for 1 hour to make self-adhesive rubber asphalt.

Embodiment 3

[0042] Add 15g minus three oil to 60g petroleum pitch, add 15g thermoplastic styrene butadiene rubber, 4g powder styrene butadiene rubber when the temperature is increased to 180℃, stir for 0.5 hours, after the temperature rises to 200℃, enter the colloid mill to grind, and grind it three times , Add 3g coumarone resin, 1g petroleum resin, 2g terpene resin, 1.5g small molecular weight polyisobutylene, 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 self-adhesive rubber asphalt prepared in Examples 1 to 3 was cooled to 150±5°C, and the low-temperature-resistant self-adhesive rubber asphalt waterproof roll was made through the processes of release paper unwinding, self-adhesive coating, cooling, film coating, and cooling setting. 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 workwell 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 well-known self-adhesive construction method self-adhesive rubber asphalt waterproofing membrane is based on SBS and other elastomer modified asphalt, and strong waterproof polyethylene film or aluminum foil is used as the upper surface material of the membrane or no film (double-sided self-adhesive ), a tyreless self-adhesive waterproof membrane made of peelable silicon-coated film or silicon-coated crepe paper as the lower surface anti-adhesive isolation layer material. The product complies with the national industry standard of JC 840-1999 "Self-adhesive rubber asphalt waterproof membrane". [0003] The above-known self-adhesive rubber-asphalt waterproofing membrane has the foll...
