Abstract

The invention belongs to the technical field of building materials, and particularly relates to a polymer modified asphalt rubber material and a preparation method thereof as well as a waterproof coiled material. Aiming to solve the technical problems of poorer high temperature performance, low temperature performance and anti-aging performance of an existing modified asphalt rubber material, the polymer modified asphalt rubber material and the preparation method thereof are provided. A raw material formula the rubber material comprises petroleum asphalt, a polymer modifying agent, softening oil, a tackifier, tyre rubber powder, an organic additive and an inorganic nano-material. Meanwhile, the invention also discloses the preparation method of the polymer modified asphalt rubber material. The polymer modified asphalt rubber material provided by the invention has better high temperature performance and low temperature performance; moreover, according to the waterproof coiled material containing the polymer modified asphalt rubber material, the aging resistant performance is enhanced, and the service life of the waterproof coiled material is prolonged.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a polymer-modified asphalt rubber compound, a preparation method thereof, and a waterproof coiled material. Background technique [0002] Petroleum asphalt is the last residue in the process of crude oil processing. It is cheap and easy to get. Asphalt is a hydrophobic material. It is impermeable and almost insoluble in water. The aging performance is also very prominent, so it is widely used in the field of waterproofing. However, matrix asphalt is easy to soften and flow at high temperature, and brittle at low temperature, making it difficult to be directly applied to waterproof membranes. [0003] In recent years, researchers have gradually added high-polymer modified matrix asphalt to petroleum asphalt, which has greatly improved the high-temperature and low-temperature performance of asphalt, but the widely used styrene-butadiene-styrene embedded The...
