Embodiment 1

[0071] Modified asphalt coating material

[0072] A modified asphalt coating material, comprising the following raw materials by weight: 90# asphalt, 100 parts; trioctyl phosphate, 1.5 parts; rubber oil, 45 parts; SBS, 8 parts; SBR, 7 parts; tire Rubber powder, 50 parts; heavy calcium, 50 parts.

[0073] (1) Mix 90# asphalt, trioctyl phosphate and rubber oil according to the ratio, stir the mixture at a speed of 1000rpm, raise the temperature to 140~145°C and keep it warm for 1.5h until the asphalt is completely melted;

[0074] (2) Add SBS and SBR to the mixture after step (1) in accordance with the ratio, raise the temperature to 170~180°C and keep it warm for 1.5h;

[0075] (3) Add tire rubber powder to the mixture after heat preservation in step (2) according to the ratio, raise the temperature to 170~180°C, and shear and disperse at this temperature at a speed of 1000rpm for 2.5h;

[0076] (4) Add heavy calcium powder to the mixture after shear dispersion in step (3), ...

Embodiment 2

[0081] The preparation of the modified asphalt coating material and the asphalt waterproofing membrane are the same as in Example 1, the difference is that the content of each component in the modified asphalt coating material is different from that of Example 1, and each component is in parts by weight: 90 #Asphalt, 100 parts; trioctyl phosphate, 0.5 parts; rubber oil, 40 parts; SBS, 5 parts; SBR, 5 parts; tire rubber powder, 40 parts; heavy calcium, 40 parts.

Embodiment 3

Abstract

The invention relates to the field of building waterproofing, and particularly discloses a modified asphalt coating material, a method for preparing the modified asphalt coating material and an asphalt waterproof coiled material. The modified asphalt coating material comprises the following raw materials by weight: 100 parts of matrix asphalt, 0.5 to 3 parts of an asphalt modifier, 40 to 50 parts of asphalt softening oil, 5 to 10 parts of SBS (styrene butadiene styrene); 5 to 10 parts of SBR (Styrene Butadiene Rubber); 40 to 60 parts of rubber powder, and 40 to 60 parts of a powder material. The asphalt modifier is selected from one or more of trioctyl phosphate, triphenyl phosphate, tributyl phosphate, tert-butyl perbenzoate and acetyl tributyl citrate. According to the modified asphalt coating material provided by the invention, by adding the asphalt modifier, the compatibility among the components in the coating material can be effectively improved, so that the durability and low-temperature flexibility of the prepared asphalt waterproof coiled material can be greatly improved, and the application requirements in the field of building waterproofing are met.

Description

technical field [0001] The application relates to the field of building waterproofing, in particular to a modified asphalt coating material, a method for preparing the modified asphalt coating material and an asphalt waterproof coiled material. Background technique [0002] Waterproof membrane is mainly used in building walls, building basements, floors, roofs, tunnels, roads, landfills, etc., to resist the penetration of external rainwater and groundwater. It is a flexible building material product that can be rolled into rolls. , as the non-leakage connection between the engineering foundation and the building, it is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. [0003] At present, the asphalt waterproofing membrane required by the domestic building waterproofing industry generally hopes that the product will still have ultra-high bonding strength and low-temperature flexibility after long-term storage or long-...
