Abstract

The invention relates to the technical field of asphalt, and provides modified asphalt and a preparation method thereof. The modified asphalt is prepared from the following components in parts by weight: 35-50 parts of matrix asphalt, 2-5 parts of tourmaline powder, 2-5 parts of a nano material, 0.1-0.5 parts of a nano particle surface modifier, 1-3 parts of a dispersion stabilizer, 3-8 parts of SBS (Styrene Butadiene Styrene), 2-6 parts of resin, 6-12 parts of softening oil, 5-15 parts of rubber powder, 25-40 parts of filler, 0.5-1 part of sodium stearoyl lactylate, and 1-1.5 parts of trimethylolpropane trimethacrylate. According to the technical scheme, the problem that the modified asphalt in the prior art is poor in high and low temperature resistance and easy to crack and deform is solved.

Description

technical field [0001] The invention relates to the technical field of asphalt, in particular to a modified asphalt and a preparation method thereof. Background technique [0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It is liquid and has a black surface. It is soluble in carbon disulfide. Organic gelling materials are widely used in building materials, coatings, plastics, rubber and other industries, as well as paving roads. [0003] Asphalt used in construction must have certain physical properties and adhesion, good elasticity and plasticity under low temperature conditions, sufficient strength and stability under high temperature conditions, and anti-aging ability under processing and use conditions . However, due to its own composition and structure, ordinary asphalt has poor temperature-sensing performance, poor elasticity and a...
