However, when building a garden on the roof, the first thing to encounter is the waterproof problem. The widely used modified asphalt waterproof material is easy to be penetrated by the roots of the plants during use, causing roof leakage. The copper that is currently on the market The anti-root waterproof material made of tire base and SBS modified asphalt is expensive and difficult to popularize and apply. People urgently need a kind of high-quality, low-cost self-adhesive compound anti-root and multi-channel waterproof fortification for roof gardens. s material

[0015] Preparation process of the present invention
[0016] 1. Preparation of self-adhesive chemical anti-root waterproof layer
[0017] The self-adhesive chemical anti-root waterproof layer is composed of self-adhesive polymer modified asphalt anti-root mixture made of the following raw materials by weight, asphalt 45-55, recycled styrene-butadiene rubber powder 20-30, base oil 5-15, Heavy calcium powder 15-20, chemical root inhibitor 0.8-1.2.
[0018] The asphalt in the self-adhesive polymer modified asphalt anti-root mixture of the present invention is road petroleum asphalt, the chemical anti-root agent adopts phenoxy fatty acid lipid chemical anti-root agent, and the physical anti-root waterproof layer is polyethylene, polyvinyl chloride, A kind of root puncture-resistant waterproof material such as high-density polyethylene geomembrane and polyethylene polypropylene fiber.
[0019] The polymer in the self-adhesive polymer modified asphalt root-resistant mixture of the...
Embodiment 1
[0021] Embodiment 1 (every part by weight is 100 kilograms)
[0022] Add 4,600 kg of No. 90 asphalt into the mixing tank, raise the temperature to 215°C under stirring, add 2,900 kg of regenerated styrene-butadiene rubber powder, and stir for 90 minutes at 215°C. At this time, add 900 kg of base oil, and then add heavy calcium Powder 1600 kg, lower the temperature to 130°C-150°C, finally add 100 kg of chemical root inhibitor, and stir for 30 minutes to obtain the finished self-adhesive polymer modified asphalt root-resistant waterproof mixture for later use.
Embodiment 2
[0024] Add 4,800 kg of No. 100 asphalt into the mixing tank, raise the temperature to 210°C under stirring, add 3,000 kg of recycled SBR powder, stir at 205°C for 90 minutes, add 700 kg of base oil, and add heavy calcium at this time Powder 1700 kg, lower the temperature to 130°C-150°C, finally add 80 kg of chemical anti-root agent, and stir for 30 minutes to obtain the finished self-adhesive polymer modified asphalt anti-root waterproof mixture for future use.

Abstract
The invention relates to a novel building waterproof material in a building roof engineering technology and a planting roof engineering technology and a preparation method, in particular to a self adhesive polymer and modified bitumen composite root resistance waterproof membrane and a preparation method thereof, wherein the membrane uses a self-adhibiting method for cold construction and has chemical root resistance and physical root resistance and two waterproof barriers. The membrane has a multi-layer laminar structure formed by a covering, a self-adhesive chemical root resistance waterproof layer, and a physical root resistance waterproof layer which are orderly combined; and the method for preparing the membrane comprises the following steps: firstly, a polymer and modified bitumen root resistance composite material of the self-adhesive chemical root resistance waterproof layer is produced, then heavy calcium carbonate powder is added, and finally a chemical root inhibitor is added to produce the polymer and modified bitumen root resistance composite material; then the polymer and modified bitumen root resistance composite material is coated on a polyethylene root penetration resistant waterproof material with thickness control, and is subjected surface coating, cooling, and winding packaging, and thus a finished product of the membrane is obtained. The popularization and application of the membrane on roof gardens play an active role in facilitating the improvement on the dwelling environment of people.
Description
technical field [0001] The invention relates to a new type of building waterproof material and its preparation method in building roofing engineering technology and planting roofing engineering technology. Self-adhesive polymer modified asphalt composite anti-root waterproof membrane with two waterproof fortifications and its preparation method. Background technique [0002] With the continuous expansion of urban construction, people's living standards continue to improve, land prices in big cities continue to rise, the area of green space in people's living environment is getting smaller and smaller, and the rational use of roof area is gradually put on the agenda, such as building gardens on the roof, planting Flowers, medicinal materials, vegetables, small shrubs and other green plants can beautify and improve the environment, purify the air, reduce the urban heat island effect, and provide people with roofs to rest and carry out entertainment activities. However, when...
