Abstract

The invention discloses a cooling polymer modified asphalt material which is characterized by comprising the following components in parts by weight: 55-65 parts of asphalt, 20-30 parts of sulfonic modified asphalt, 5-7 parts of a functional copolymer, 3-5 parts of micron powder and 1-3 parts of a coupling agent, wherein the functional copolymer is prepared from 3-[N,N-dimethyl[2-(2-methylprop-2-enoyloxy)ethyl]ammonium]propan-1-sulfonic acid inner salt, 2-acrylamide-2-methylpropanesulfonic acid, polyethylene glycol monoallyl ether and N-(4-cyano-3-trifluoromethylphenyl)methacrylamide through a copolymerization reaction. The invention also provides a preparation method of the cooling polymer modified asphalt material. The cooling polymer modified asphalt material provided by the invention is better in thermal stability, stronger in durability and ageing resistance, lower in storage and transportation temperature and longer in service life.

Description

technical field [0001] The invention relates to the technical field of asphalt materials, in particular to a cooling polymer modified asphalt material and a preparation method thereof. Background technique [0002] Asphalt material has excellent waterproof and anti-corrosion properties, and is widely used in civil engineering, mainly used in waterproofing of roofs, grounds, and underground structures, and anti-corrosion of wood and steel. In addition, it is also a widely used pavement structure cementing material in road engineering. However, due to the significant temperature sensitivity of asphalt (easy to soften at high temperature and easy to crack at low temperature), low mechanical properties and elastic properties, it is easy to age and lead to cracking and loosening. Significant thermal sensitivity prevents asphalt mixtures from exhibiting good performance at high and low temperatures, and asphalt properties must be modified to enhance product performance.
